PFA Material Guide: Siab -Kev Ua Haujlwm Fluoropolymer Applications

Ib tug neeg los ntawm lub tuam txhab khoom semiconductor hu rau peb lub Kaum Hli kawg nug seb peb puas tuaj yeem extrude PFA tubing. Peb ua tsis tau. PFA yog lub ntiaj teb sib txawv kiag li los ntawm PVC, PC, thiab ABS profiles peb khiav txhua hnub. Tab sis kuv tau mus rau hauv xov tooj nrog nws li plaub caug feeb, vim nws ntxhov siab thiab xav tau ib tug neeg los tham txog cov khoom nrog. Nws tau sim muab cov khoom siv semiconductor-qib PFA fittings rau peb lub hlis. Peb lub hlis. Cov sij hawm ua ntej tau hais hauv peb lub hlis twg, tsis yog lub lis piam. Yam tsawg kawg nkaus txiav txim kom muaj nuj nqis uas ua rau tsis muaj kev nkag siab rau nws tus qauv ua haujlwm.

PFA Material Guide: High-Performance Fluoropolymer Applications

Qhov kev sib tham ntawd yog vim li cas kuv thiaj sau qhov no. Tsis yog vim peb muag PFA - peb tsis ua, thiab kuv yuav ua ntej txog qhov kawg - tab sis vim tias nyob rau lub hlis txij li ntawd, kuv tau nkag mus tob rau ntawm cov khoom no. Tham nrog fluoropolymer processors, nyeem los ntawm Solvay's thiab Daikin cov ntaub ntawv kev qhia, khawb rau hauv SEMI specifications, lurked hauv Eng-Cov lus qhia uas tib neeg tau tham txog cov teeb meem ua tiav tiag tiag. Qhov kuv pom yog cov khoom siv uas cov ntaub ntawv tsis raug nqi cov neeg yuav khoom loj thiab qhov sib txawv ntawm "Kuv nyeem cov ntaub ntawv" thiab "Kuv nkag siab cov ntaub ntawv" yog dav dua yuav luag txhua yam hauv plastics.

Yog tias koj yog tus thawj saib xyuas kev yuav khoom lossis tus kws tshaj lij ntsuas PFA, qhov no yog qhov kuv xav kom ib tus neeg tau hais rau tus txiv neej hauv xov tooj.

Yog vim li cas PFA tshwm sim (Thiab yog vim li cas nws raug nqi nws ua)

PFA yog fluoropolymer, tib tsev neeg li PTFE - cov khoom uas neeg hu ua Teflon. Ib tsev neeg zoo li FEP. Tag nrho peb tus tiv thaiv yuav luag txhua yam tshuaj hauv ntiaj teb, tswj qhov kub thiab txias, thiab muaj lub zog saum npoo qis uas yuav luag tsis muaj dab tsi lo rau lawv.

Qhov sib txawv uas ua kom pom tseeb ntawm PFA lub neej thiab nws cov nqi tag: koj tuaj yeem yaj- txheej txheem nws. Txhaj tshuaj molding, extrusion, vuam. PTFE tsis tuaj yeem ua ib qho ntawm qhov ntawd. PTFE yuav tsum tau compression- molded los ntawm hmoov thiab sintered, zoo li ceramics yuav luag. Yog hais tias koj xav tau ib tug yooj yim gasket los yog bushing, zoo. Yog hais tias koj xav tau ib tug complex manifold nrog sab hauv, koj nyob nraum machining nws los ntawm sintered billet Tshuag, thiab tus nqi ntawm ib tug -unit tau txais dab tuag sai sai.

Dab tuag li cas? Savillex, tus kws tshaj lij fluoropolymer molding tshwj xeeb, luam tawm cov lej qhia cov tshuab PTFE ntawm kwv yees li $ 300 piv rau tib qhov kev txhaj tshuaj geometry - molded hauv PFA ntawm ib ncig ntawm $ 50 (savillex.com). Qhov ntawd yog 83% txo nqi. Ntawm 10,000 units ib xyoos twg, koj tab tom saib $ 2.5 lab hauv kev txuag nyiaj. Cov cuab yeej txhaj tshuaj pwm - $ 15,000 txog $ 50,000 nyob ntawm qhov nyuaj - them rau nws tus kheej hauv thawj ob peb puas ntu.

Yog li PFA tsis kim. Nws kimyog koj muab piv rau qhov tsis ncaj ncees lawm. Piv rau PTFE rau qhov nyuaj, PFA yog qhov kev xaiv pheej yig.

MFR yuam kev uas raug nqi ntau dua li lwm yam

Kuv yuav tsum tau tham txog qhov no ua ntej lwm yam, vim qhov no yog qhov uas kuv pom cov nyiaj siv ntau tshaj plaws raws li kev sib tham nrog cov neeg hauv cov saw hlau fluoropolymer.

Cov qib PFA raug cais los ntawm cov dej ntws tawm - MFR, ntsuas hauv grams ib 10 feeb ntawm 372℃. MFR siab dua txhais tau tias cov khoom ntws yooj yim dua thaum ua. Cov pab pawg yuav khoom ib txwm ua rau siab dua MFR vim tias cov txheej txheem nyiam nws: yooj yim rau pwm, nrawm dua, tsis kam lees tsawg dua.

Nov yog qhov teeb meem tsis muaj leej twg hais txog kom txog thaum lig dhau lawm.

Solvay's Hyflon PFA daim ntawv qhia tsim suav nrog cov ntaub ntawv flex lub neej uas yuav tsum tau luam tawm ntawm txhua PFA kev yuav khoom: qib ntawm MFR 14 g / 10min tuaj yeem muaj sia nyob ntau dua 500,000 flex cycles. Thawb ntawd MFR mus txog rau 30+ thiab koj tab tom saib ntawm 18,000 txog 25,000 cycles (solvay.com). Qhov ntawd tsis yog ib qho kev lag luam me me - nws yog 20 × txo qis hauv lub neej qaug zog los ntawm qhov tshwj xeeb uas cov neeg yuav khoom feem ntau tsis tau kuaj xyuas thaum tuaj xyuas.

Xav txog tias koj tab tom nrhiav PFA tubing rau cov neeg hlau wafer tuav. Cov hlab flex txhua lub voj voog. Koj tus txheej txheem qhia txog qib siab -MFR vim nws ua haujlwm zoo dua ntawm lawv cov khoom siv. Tsis muaj leej twg tshawb xyuas flex lub neej vim MFR tsuas yog spec ntawm PO. Kaum yim lub hlis tom qab cov hlab no pib tawg, koj cov neeg siv khoom fab kab poob qis, thiab lub hauv paus ua rau cov kab rov qab mus rau qhov kev txiav txim siab yuav khoom uas ua ntej ua kom yooj yim dua li daim ntawv thov.

Kuv tsis speculating. Ntau tus kws tshaj lij fluoropolymer kuv tau hais nrog hais tias qhov no yog qhov feem ntau PFA specification yuam kev uas lawv pom. Nws tseem tshwm sim vim hais tias cov ntaub ntawv flex lub neej tau faus rau hauv cov chaw tsim khoom tsim cov lus qhia uas pawg neeg yuav khoom tsis tau nyeem - lawv tsuas saib ob - nplooj TDS.

Qhov kuv paub tiag tiag txog Fluoropolymer Properties (Thiab qhov kuv yuav tsum tau saib)

Kuv yuav ncaj ncees ntawm no. Kuv ua hauj lwm nrog cov pa engineering yas. PVC, ABS, PC - Kuv tuaj yeem qhia koj qhov kev ua haujlwm kub rau cov uas kuv pw tsaug zog. PFA yog thaj chaw tshiab rau kuv, thiab qee qhov kuv kawm tau ua rau kuv xav tsis thoob.

Lub thermal range yog insane. Kev pabcuam txuas ntxiv los ntawm -200℃mus rau +260℃. Peb tab tom khiav PVC ntawm 150-190℃tuag kub thiab txhawj txog degradation; PFA extrusion tuag kub ntaus 400 degree. Lub qhov rais ua haujlwm zaum nyob ib sab ntawm qhov chaw uas cov khoom pib decomposing rau hauv hydrogen fluoride gas - tiag tiag toxic, tiag corrosive, xav tau kev mob siab rau lub tshuab cua thiab tus neeg teb xov tooj kev cob qhia kev nyab xeeb uas mus dhau ib yam dab tsi nyob rau hauv cov pa yas ua. Ib tsab xov xwm Plastics Technology tau piav qhia txog qhov xwm txheej uas Hastelloy C-276 extrusion ntsia hlau - cov nqi no ntau dua li cov qauv steel screws - snapped thaum lub caij txias vim tias tus neeg teb xov tooj tsis suav nrog cov hlau tsis muaj zog (ptonline.com). Qhov ntawd yog hom kev ua yuam kev uas raug nqi tsib tus lej thiab ib lub lim tiam ntawm kev poob qis.

What I Actually Know About Fluoropolymer Properties (And What I Had to Look Up)

Lub zog dielectric ntes kuv lub siab vim qhov sib piv nrog PTFE. PFA hits 35 txog 100 kV / mm nyob ntawm thickness. PTFE? 20-25 kV / hli Peb mus rau plaub zaug ntawm qhov voltage breakdown resistance. Rau aerospace hlau rwb thaiv tsev, uas ncaj qha txhais mus rau thinner rwb thaiv tsev txheej thiab sib dua cable bundles ib 'meter'. Yog tias koj nyob hauv qhov kev lag luam ntawd, cov cuab yeej no ib leeg yuav tsim nyog rau cov khoom siv.

Cov ntaub ntawv permeation kuv pom qhov nthuav tshaj plaws - thiab feem ntau cuam tshuam rau txhua tus hauv kev ua tshuaj lom neeg - los ntawm Solvay's design guide and E9Inerte's published data. Tawm tsam concentrated sulfuric acid, PFA yog qhov tseem ceeb impermeable. Hydrochloric acid ntawm 37%, tus nqi permeation yog tswj tau ntawm 0.20 g·mm / m² / hnub. Tab sis hydrofluoric acid, uas yog ib qho tseem ceeb tshaj plaws tshuaj nyob rau hauv semiconductor ntub ua, permeates PFA ntawm 10 mus rau 100 npaug ntawm tus nqi ntawm HCl (e9inerte.com). Me me molecule, tau los ntawm cov polymer matrix ntau yooj yim dua. Qhov no yog vim li cas semiconductor fabs tsis tuaj yeem tsuas yog yuav ib qib PFA rau HF kev pabcuam - lawv xav tau cov resins tshwj xeeb, tswj crystallinity, thiab cov txheej txheem ua kom txias dua thaum lub sijhawm tsim khoom. Yog tias koj tus neeg muag khoom tsis paub qhov no, lawv tsis yog semiconductor-qib tus neeg muag khoom txawm hais tias lawv lub vev xaib hais li cas.

PTFE thiab FEP: Siv nrawm, Tsis yog Daim Ntawv Sau

Kuv yuav tsis ua qhov uas kuv muab txhua qhov chaw sib npaug thiab ua piv txwv tias lawv txhua tus zoo sib xws hauv ntau txoj kev. Los ntawm qhov kuv tau sau los tham nrog cov neeg ua haujlwm nrog peb:

PTFE tseem yog huab tais rau raw tshuaj tiv thaiv thiab flex lub neej. Siab melting point ntawm 327℃piv rau PFA's 290-315 degree. Yog tias koj daim ntawv thov yog ib qho yooj yim zoo nyob rau hauv ib puag ncig chemical hnyav thiab koj tsis mloog tus nqi machining, PTFE muaj pov thawj thiab pheej yig dua ib kilo. Feem ntau cov txheej txheem fluoropolymer kuv tau tham nrog tseem ua rau PTFE tshwj tsis yog tias cov geometry lossis purity yuav tsum yuam lawv mus rau PFA.

FEP kuv paub tsawg dua vim tias tsawg tus neeg kuv tham tau siv nws ntau heev. Qhov kev txwv loj txhua tus hais txog: 200℃max kev pabcuam txuas ntxiv, rau caum degrees hauv qab PFA thiab PTFE. Thiab lub neej flex yog kwv yees li ib -feem kaum ntawm PFA, uas txwv tsis pub nws tawm rau kev siv dynamic. Qhov twg nws tau teev tseg yog daim ntawv thov zoo li qub uas qhov pom kev pom tseeb tseem ceeb - nws yog qhov pob tshab tshaj plaws ntawm peb. Tab sis ncaj ncees, yog tias ib tug neeg xaiv ntawm FEP thiab PFA, qhov kev txiav txim siab feem ntau twb tau ua los ntawm qhov kub thiab txias.

PVDF tuaj txog hauv nqe lus sib tham vim tias nws yog li 30% pheej yig dua PFA. Kuv tau muaj cov kws tsim khoom siv qhia kuv tias PVDF tuav "feem ntau" tshuaj zoo. Technically muaj tseeb. Tab sis "feem ntau" tsis suav nrog cov hauv paus muaj zog, qee yam amines, lossis cov txheej txheem inertness semiconductor xav tau. Ib qho tshuaj ua cov nroj tsuag muab cov kav dej ntau yuav ntsuas PVDF tiag tiag. Semiconductor? Tshuaj? Tsis txhob thab.

Leej twg ua PFA thiab vim li cas nws tseem ceeb rau leej twg koj yuav los ntawm

Plaub lub tuam txhab tswj kev lag luam no. Kuv yuav hais ncaj qha ntxiv txog qhov kuv tau hnov txog txhua tus tshaj li cov lus qhia feem ntau, vim hais tias kev nom kev tswv qhov tseeb uas txhua tus tau txais kev qhuas vaj huam sib luag tsis muaj txiaj ntsig thaum koj tab tom sim ua qhov kev txiav txim.

Chemours(US) - Teflon PFA. Kev lag luam loj tshaj plaws, kwv yees li ib feem peb ntawm cov khoom siv thoob ntiaj teb. Lawv cov qib 400HP thiab 900HP Plus yog cov neeg ua haujlwm hauv kev lag luam semiconductor. Yog tias koj nyob hauv Asmeskas thiab koj qhov project kov CHIPS Txoj Cai nyiaj txiag, Chemours tau txais txiaj ntsig los ntawm kev nyiam hauv tsev - cov ntsiab lus. Tus nqi qhia txog kev ua lag luam - lawv tsis yog tus pheej yig tshaj, thiab lawv paub nws. Tab sis muab kev ntseeg siab zoo li zoo dua li lwm txoj hauv kev rau North American buyers.

Daikin(Nyiv) - Neoflon PFA. AP -231SH yog qhov feem ntau Asian semiconductor fabs qhia. Lub "SH" txhais tau tias ruaj khov hydrocarbon kawg pab pawg, uas yog ib qho tseem ceeb rau semiconductor purity - Kuv mam li piav qhia vim li cas ib pliag. Daikin lub zog yog Japanese thiab Korean fab mov saw. Lawv qhov tsis muaj zog, los ntawm qhov kuv tau hais los ntawm ob tus neeg yuav khoom sib txawv: US warehouse stock available can be inconsistent. Yog tias koj tab tom ua haujlwm tsuas yog- nyob rau hauv-lub sijhawm ua haujlwm ntawm East Coast, tsim nyob rau hauv tsis muaj.

Solvay(Belgium) - Hyflon PFA. Cov qib M-series qib (M620, M640) yog paub txog qhov tshwj xeeb ntawm cov npoo sab hauv, uas tseem ceeb rau cov ntawv thov ntws. European chemical processing tuam txhab uas muag yuav zoo li no. Cov txheej txheem kev qhia lawv tshaj tawm yog cov ntaub ntawv zoo tshaj plaws ntawm cov ntaub ntawv - feem ntau ntawm cov kev ua haujlwm uas kuv tau hais hauv tsab xov xwm no yog los ntawm nws. Ntawm kev lag luam, Kuv tau hnov cov lus tawm tswv yim sib xyaw txog lub sijhawm teb los ntawm lawv lub koom haum muag khoom European. Cov cheeb tsam lub sij hawm yog ib feem ntawm nws, tab sis ntau tus neeg tau hais tias tau txais cov lus teb rau cov lus nug txog kev lag luam muaj peev xwm nce mus txog lub lis piam.

AGC tshuaj(Nyiv) - Fluon PFA. Npog qhov ntau ntawm MFR- cov qib tshwj xeeb. Nyiam los ntawm qee cov Japanese thiab Korean OEMs. Kuv tsis muaj cov lus qhia ncaj qha txaus los ntawm cov neeg yuav khoom txog AGC kom muaj zog thov ib txoj kev lossis lwm qhov, yog li kuv yuav tso nws ntawm qhov ntawd.

Nov yog qhov kev pom kev xaiv qib uas cuam tshuam rau koj qhov kev txiav txim siab yuav khoom: MFR txiav txim siab txog koj txoj kev ua thiab kev thov kom haum. Qhov 0.8-3.0 g/10min ntau yog rau compression thiab hloov molding - tuab-walled fittings, hlab ntsha hauv ob sab phlu, siab ntxhov siab-tawg tsis kam qhov chaw. 3.0-18 g/10min npog daim ntaub ntawv extrusion. Tshaj li 16 los yog li ntawd, txhaj tshuaj molding ua tswv yim rau complex geometry.

Thiab qhov sib txawv tseem ceeb tshaj plaws: tus qauv piv rau SH (stabilized hydrocarbon) qib. Standard PFA muaj cov pab pawg tsis ruaj tsis khov ntawm cov khoom siv los ntawm polymerization uas tuaj yeem tso cov kab mob ionic mus rau hauv cov kua dej. Rau kev lag luam tshuaj tuav, tsis muaj leej twg saib xyuas. Rau cov txheej txheem ntub dej semiconductor qhov kev sib kis tau ntsuas nyob rau hauv ib feem ntawm trillion, cov pab pawg kawg yog kev sib cog lus -breaker. Cov qib SH tau txais kev ua haujlwm ntxiv kom tsis txhob ua rau lawv. Daikin's AP-231SH, piv txwv li, ua tiav tag nrho cov pa roj carbon monoxide ntawm 0.2% ntawm SEMI F57 txwv. Yog tias ib tus neeg muag khoom tau hais koj "PFA" rau daim ntawv thov semiconductor yam tsis tau qhia meej SH-qib purity, nug cov lus nug nyuaj txog qhov lawv tab tom muab.

Qhov xwm txheej PFAS: Kuv Coj

Txhua phau ntawv qhia ntawm fluoropolymer tam sim no suav nrog ib ntu hais txog PFAS kev tswj hwm thiab feem ntau ntawm lawv tau nyeem zoo li xov xwm tshaj tawm - ntawm no yog qhov EU tau hais, ntawm no yog qhov EPA tau hais, ntawm no yog qhov kev lag luam hais. Qhov ntawd tsis muaj txiaj ntsig. Nov yog qhov kuv xav tias tseem ceeb rau cov neeg yuav khoom.

PFA yog technically cais raws li PFAS raws li kev cai dav dav. Qhov no yog, frankly, ib qho teeb meem categorization. Zeus Industrial Products luam tawm ib qho kev soj ntsuam ua qhov sib txawv: PTFE chains muaj 10,000 txog 180,000 txuas carbons. Cov me me -molecule PFAS cov tebchaw uas paug cov dej haus - PFOA, PFOS - muaj 4 txog 12 carbons (zeusinc.com). Kev sib piv ob chav kawm ntawm cov tshuaj no zoo li muab piv rau lub hnab ntim khoom noj polyethylene rau cov roj ethylene vim tias lawv yog "hydrocarbons." Technically muaj tseeb, xyaum tsis muaj nuj nqis.

Tab sis cov txheej txheem tswj hwm tsis tas ua raws li kev xav tau.

EU PFAS txwv qhov kev thov yuav txav mus los ntawm ECHA nrog sector-los ntawm-sector kev ntsuam xyuas xav txog txog 2026, muaj peev xwm nkag mus rau hauv 2027-2028. Kev tsim khoom semiconductor yog dav xav kom tau txais derogation - tej zaum yuav txog ib ncig ntawm 2040 - vim tias tag nrho kev lag luam tau siv ob xyoos qhia cov neeg tswj hwm tias tsis muaj cov khoom siv hluav taws xob hauv ntiaj teb tuaj yeem ua haujlwm yam tsis muaj fluoropolymer Cheebtsam. Lub Semiconductor PFAS Consortium ntawm SIA tau tsim cov ntaub ntawv dav dav rau cov txiaj ntsig no.

Hauv Teb Chaws Asmeskas, TSCA tshaj tawm cov cai uas tau mus nyob hauv 2025 suav nrog cov ntsiab lus uas ntes tau ntau tus neeg xa khoom tawm ntawm tus neeg saib xyuas: yog tias koj xa cov khoom uas muaj PFAS, koj raug suav tias yog "PFAS cov chaw tsim khoom" rau kev tshaj tawm cov hom phiaj. Tsis muaj kev zam minimis. Yog tias koj lub tuam txhab nqa PFA fittings los ntawm txawv teb chaws, koj muaj peev xwm tshaj tawm cov luag num.

Qhov no txhais tau li cas rau kev xyaum:yuav tam sim no, npaj rau volatility.Tuam Tshoj tswj 55-60% ntawm lub ntiaj teb fluorspar - cov khoom noj ntxhia rau tag nrho cov fluoropolymer. Kwv yees li ib feem peb ntawm cov neeg tsim khoom tau tshaj tawm txog kev cuam tshuam cov khoom noj tsis ntev los no. Lub sijhawm ua haujlwm rau cov qib tshwj xeeb PFA tau nthuav tawm los ntawm keeb kwm 4-8 lub lis piam mus rau 12+ nyob rau lub sijhawm ncov. Thiab cov nqi tswj kev ua raws cai tau thawb cov nqi tsim khoom nce 20-30% txij li xyoo 2022.

Kuv tsis tau hais tias PFA yuav dhau los ua tsis muaj. Semiconductor fabs tseem ceeb heev, thiab txoj kev zam kom pom tseeb. Tab sis kev txwv nruj thiab tus nqi nce tau tshwm sim lawm, thiab kev tswj hwm tsis paub meej ua rau cov neeg xa khoom siv zog ntawm tus nqi uas lawv tsis muaj tsib xyoos dhau los. Yog tias PFA tseem ceeb rau koj qhov kev ua haujlwm, ob qho - kev muab khoom thiab cov khoom muag tsis yog kev coj ua zoo xwb - lawv yog qhov ceev.

Kev Ua Haujlwm: Yam Koj Yuav Tsum Nug Koj Fabricator

Kuv tsis yog fluoropolymer processor. Kuv extrude PVC thiab ABS. Tab sis kuv paub txaus txog extrusion los ntsuas qhov kuv tau nyeem, thiab muaj cov lus nug tshwj xeeb uas koj tuaj yeem nug tus neeg muag khoom PFA uas yuav qhia koj sai sai seb lawv puas paub tias lawv ua dab tsi.

Nug txog lawv cov ntsia hlau tsim.PFA xav tau ib qho - davhlau screws nkaus xwb. Barrier flight designs - standard in polyolefin extrusion - yuav tsum zam tag nrho vim PFA lub siab yaj viscosity thiab shear rhiab heev ua rau barrier screws ib tug guaranteed qhov chaw ntawm degraded khoom, dub specks, thiab gels. Yog tias koj tus neeg tsim khoom hais txog kev thaiv cov ntsia hlau, taug kev mus.

Nug txog ntsia hlau metallurgy.PFA yaj corrodes txheem cuab yeej steel. Cov thoob thiab cov ntsia hlau xav tau Hastelloy C-276 lossis Inconel 625. Cov hlau no muaj li ntawm ib nrab ntawm cov khoom siv hluav taws xob ntawm cov pa roj carbon monoxide. Qhov no yog vim li cas txias pib snap screws - lub cev muaj zog torque tshaj li qhov softer alloy yuav lis ua ntej lub polymer melts thiab lubricates lub chim. Tus neeg tsim khoom uas tau ua tiav fluoropolymer tiag tiag yuav paub qhov no los ntawm kev mob siab. Ib tug uas tsis muaj yuav muab rau koj ib tug dawb paug saib.

Nug txog kev tshawb nrhiav cov pob txha tawg.Hauv PFA tubing extrusion, yaj tawg (nto roughness hu ua "sharkskin") tshwm sim thawj zaug ntawm * sab hauv * nto. Kev kuaj pom sab nraud yuav tsis ntes nws. Ib tug zoo processor khiav endoscopic los yog seem - txiav QC checks. Ib qho tsis zoo ships tubing uas zoo nkaus li zoo rau sab nraud thiab tsis ua haujlwm.

Nug txog lawv qhov nrawm nrawm.PFA khiav ntawm 3 mus rau 50 RPM. Yog hais tias ib tug neeg qhia rau koj tias lawv khiav fluoropolymers ntawm speeds typical rau pa plastics - 60+ RPM - lawv yog dag los yog degrading cov khoom thiab tsis paub nws.

Ib yam los ntawm Solvay cov lus qhia ua haujlwm uas ua rau kuv zoo siab ua tus extruder: PFA pom tau tias muaj "super- thaj av extrusion" saum toj ntawm cov pob txha tawg, qhov chaw zoo * txhim kho dua * ntawm tus nqi siab heev. Cov txheej txheem kev paub siv qhov no kom ua tiav cov kab nrawm dua yam tsis muaj kev cuam tshuam qhov chaw tiav. Qhov ntawd yog hom kev coj cwj pwm tsis zoo uas koj tsuas yog kawm los ntawm kev khiav cov khoom siv rau xyoo, thiab nws yog qhov kev sim zoo litmus rau cov khoom lag luam.

Processing: What You Should Ask Your Fabricator

Tus nqi sib tham

PFA raw resin khiav $40-80/kg rau qib industrial. Cov qib semiconductor thawb dhau $ 100 / kg. Piv nrog rau $ 1.50-3.00 / kg rau PVC thiab ABS peb siv txhua hnub, daim nplaum nplaum yog tiag tiag.

Tab sis kuv tau siv sijhawm txaus hauv kev lag luam no kom paub tias kev sib piv cov nqi raw khoom thoob plaws cov ntawv thov sib txawv yuav luag ib txwm

yuam kev. Cia kuv muab tso rau hauv cov ntsiab lus uas ua rau muaj txiaj ntsig rau tus nqi - tsom rau cov neeg yuav khoom.

Kev ua tshuaj lom neeg: PFA-lined yeeb nkab tiv thaiv stainless hlau hauv HCl kev pabcuam.Stainless hlau corrodes los ntawm 6 mus rau 12 lub hlis. PFA hauv ob sab phlu kav 10 mus rau 15 xyoo. Txawm hais tias PFA hauv ob sab phlu raug nqi 3-5 × cov hlau nws hloov, koj tsis txhob 10 mus rau 20 hloov cycles dhau ib xyoo caum. Txhua lub voj voog muaj cov nqi khoom siv, kev ua haujlwm, kev poob qis, kev pov tseg pov tseg, thiab kev pheej hmoo ua haujlwm los ntawm kev khiav dej corrosive los ntawm cov kav dej degrading. Tshaj li 10 xyoo, PFA system tag nrho cov nqi feem ntau tuaj hauv 20-40% qis dua qhov "pheej yig dua" steel xaiv.

Semiconductor: tus lej lej.Entegris tau tshaj tawm tias 1% kev txhim kho kev txhim kho hauv cov khoom siv hluav taws xob niaj hnub no sib npaug li $ 150 lab toj ib xyoo. Thaum koj cov tshuaj xa mus tubing yog qhov chaw paug uas raug nqi koj txawm tias ib feem ntawm cov txiaj ntsig ntawd, $ 100 / kg PFA resin yog qhov tsis txaus ntseeg. Txhua mega-fab tau tshaj tawm tias siv li 300 metric tons ntawm semiconductor-qib PFA. Ntawm $100/kg, uas yog $30 lab nyob rau hauv resin - tawm tsam billions nyob rau hauv txhua xyoo nti tso zis. Cov khoom siv yog ib qho yuam kev nyob rau hauv kev lag luam.

Txoj kev tsim khoom:Yog tias koj tab tom sib piv cov khoom siv PTFE rau kev txhaj tshuaj-puab PFA tivthaiv rau tib daim ntawv thov, PFA yeej ntawm ib tus nqi ntawm ib qho nqi ntawm ib qho twg. Cov ntaub ntawv Savillex kuv tau hais ua ntej qhia zaj dab neeg. Yog tias ib tus neeg hauv koj lub koom haum tab tom thaiv kev hloov mus rau PFA vim tias "cov khoom siv kim dua," lawv tab tom saib cov kab tsis raug.

PFA encapsulation - txheej txheej hlau los yog qis dua- tus nqi polymer substrate nrog PFA txheej es tsis txhob siv cov khoom PFA - txiav cov khoom siv los ntawm 60-75% thaum sib piv cov tshuaj tiv thaiv ntawm qhov ntub dej. Rau cov hlab ntsha loj thiab lub tank hauv ob sab phlu, qhov no feem ntau yog qhov ua tau zoo tshaj plaws.

Failure Modes: Cov Uas Uas Ua Tau Mob

Kuv yuav tsis sau plaub pawg tsis ua haujlwm zoo thiab piav qhia txhua tus hauv cov lus sib luag. Kuv yuav qhia rau koj paub tias cov kws kho mob yws txog dab tsi, nyob rau hauv kev txiav txim siab npaum li cas nws ua rau.

Lub zais delamination.

Qhov no yog qhov ua rau neeg txaus ntshai. PFA-kab lub nkoj zoo li zoo meej rau sab nraud, dhau qhov kev kuaj pom, khiav mus rau ib xyoos lossis kaum yim hli. Ces batch zoo pib drifting. Tsis muaj leej twg txuas nws mus rau hauv liner kom txog rau thaum ib tug neeg thaum kawg ua qhov kev soj ntsuam puas tsuaj thiab pom blistering nyob rau hauv qhov chaw. Lub liner cais tawm ntawm lub substrate thiab cov txheej txheem kua yog wicking qab nws, khaws cov kab mob, cycling rov qab mus rau hauv lub batch. Lub hauv paus ua rau yuav luag ib txwm thermal cycling kev ntxhov siab - PFA nthuav dav thiab cog lus ntau dua li cov hlau substrate, thiab yog tias tus fabricator txoj kev ua kom txias tsis tau tswj xyuas kom zoo thaum lub sij hawm hauv ob sab phlu, qhov kev ntxhov siab nyob rau hauv nws thiaj li ua rau sib cais. Kuv twb tau hais tias hom kev ua tsis tiav no tau ua rau ntau- lub hlis kev tshawb nrhiav ntawm cov nroj tsuag tshuaj vim tias qhov chaw sib kis nyuaj heev los txheeb xyuas.

Qhia qhov qhab nia tsis raug thiab nrhiav tsis tau rau 18 lub hlis.

Rov qab mus rau MFR thiab flex lub neej teeb meem. Cov tubing ua haujlwm zoo thaum lub sij hawm commissioning, nplua thaum lub sij hawm thawj zaug ua haujlwm, nplua los ntawm kev tsim nyog. Tom qab ntawd cov voj voog flex cumulative ntes tau thiab tawg pib. Tom qab ntawd koj tau tsim nyog cov khoom, tsim nws rau hauv koj lub BOM, thiab hloov nws txhais tau tias tsim nyog. Kuv tau tham nrog ib tus kws tshaj lij uas tau piav qhia qhov no yog "qhov kev yuav khoom kim tshaj plaws uas kuv tau ua pov thawj tias tsis muaj cov cuab yeej siv peev."

Bonding uas tsis tuav.

PFA lub zog saum npoo yog tsawg heev uas cov nplaum nplaum tsis muaj kev kho saum npoo yog qhov kev twv txiaj. Sodium etching ua rau daim ntawv cog lus muaj zog 4-5 × siab dua li kev kho ntshav ntshav thiab muaj ib qho kev kuaj xyuas yooj yim - qhov etched nto yuav tsum tig xim av. Lub teeb xim txhais tau tias kev kho qhov tob tsis txaus. Qee cov neeg tsim khoom thawb plasma vim tias nws nrawm dua thiab zam kev siv tshuaj lom neeg, tab sis ntau qhov chaw kuv tau sab laj hais tias plasma daim ntawv cog lus hauv fluoropolymer tsis muaj kev ntseeg siab rau txhua yam qauv. Peb tus kheej kev paub txog kev sib txuas ntawm cov yas sib txawv (qhov xwm txheej sib txawv, tab sis cov ntsiab lus cuam tshuam): txhua yam fastening nplaum nplaum txhua zaus yog tias qhov geometry tso cai rau nws. Tib txoj cai siv ntawm no.

Cov lej lag luam, luv luv

PFA-cov lag luam tshwj xeeb thoob ntiaj teb nyob ib puag ncig $ 460-470 lab (2024 kwv yees), loj hlob ntawm kwv yees li 4-5% txhua xyoo mus rau $ 670-690 lab los ntawm 2030. Kev lag luam fluoropolymer dav dav yog kwv yees li $ 10.6 billion. PFA yog ib qho me me, muaj txiaj ntsig zoo tshaj plaws uas tau tsav los ntawm cov khoom siv hluav taws xob semiconductor fab, kev hloov kho cov tshuaj ntxuav tsev, thiab cov txheej txheem tshuaj niaj hnub.

Kev loj hlob yog tsom rau cov cheeb tsam tsim cov fab tshiab - US (CHIPS Act), EU (European Chips Act), Nyiv, Is Nrias teb. Cov no yog cov kev qhia tshwj xeeb-tsav kev lag luam uas cov neeg yuav khoom yog tus nqi pheej yig- tsis txaus ntseeg tab sis siab phem rau qhov zoo thiab kev ntseeg tau ntawm kev xa khoom. Yog tias koj yog PFA fabricator nrog lub peev xwm, qhov no yog lub voj voog zoo. Yog tias koj yog ib tus neeg yuav khoom sim kaw hauv cov khoom, nkag siab tias koj lub zog poob qis thaum qhov kev thov loj hlob.

Qhov twg peb sawv

Lub sij hawm yuav ncaj nraim.

Dachang Yas tshwj xeeb hauv kev cai engineering yas profile extrusion - PVC, PC, ABS, PMMA, PP, thiab cov ntaub ntawv zoo sib xws. Peb txheej txheem tsis muaj fluoropolymer tham hauv kab lus no. Peb lub chaw, peb cov cuab yeej siv, peb cov neeg ua haujlwm txawj ntse - txhua yam ua los ntawm cov khoom siv thermoplastics.

Kuv tau sau phau ntawv qhia no vim kuv ntseeg tias muab cov ntaub ntawv tseem ceeb, txawm hais txog cov khoom peb tsis muag, ua rau peb lub koob npe nrov dua li ua piv txwv cov ntaub ntawv tsis muaj nyob. Tus neeg saib xyuas kev yuav khoom uas hu rau peb txog PFA tubing? Peb tsis tuaj yeem pab nws ncaj qha, tab sis peb taw nws mus rau ob tus neeg tsim khoom uas tuaj yeem ua tau. Nws rov qab los rau peb rau lub hlis tom qab nrog rau qhov project cais tag nrho rau PC lub teeb diffuser profiles. Qhov project tam sim no nyob rau hauv nws qhov kev tsim khoom thib peb.
