Rigid Polycarbonate Profiles: Khoom thiab Kev Siv Vaj Tsev, Nyeem Los Ntawm Tuag

Nug ob tus neeg nyob hauv ib lub tsev- cov khoom lag luam cov khoom lag luam yog cov khoom siv polycarbonate nruj, thiab feem ntau koj yuav tau txais ob lo lus teb sib txawv. Lub glazier duab cov tawv polycarbonate U-, H-, thiab R-channel profiles uas kaw cov nplooj ntawv ntau phab ntsa ua ke. Tus kws tsim hluav taws xob teeb pom kev zoo duab qhov pom tseeb lossis opal channel uas snaps hla lub LED sawb. Ob leeg yog lawm, thiab qhov sib tshooj yog raws nraim qhov kev qhia yuam kev pib. Ntawm txoj kab extrusion, lub sij hawm npog ib qho txuas txuas ntxiv -section raug thawb los ntawm qhov tuag thiab txiav kom ntev: glazing caps, diffuser npog, optical lo ntsiab muag, structural edge banding, snap- haum connectors. Nws tsis yog daim ntawv tiaj tus, thiab nws tsis yog ib qho muag muag. Khaws cia ciam teb kom meej yog thawj qhov kev txiav txim siab uas tus neeg tau txais los ntawm pebpolycarbonate profile kabyuav tsum tau ua, vim tias daim ntawv thiab qhov profile uas nqa nws tau teev tawm tsam tus lej sib txawv thiab ua tsis tiav rau qhov sib txawv.

Qhov twg cov khoom khwv tau nws qhov chaw ntawm ib lub tsev

Polycarbonate tseem tshwm sim ntawm facades, canopies, taug kev, thiab teeb pom kev zoo rau cov laj thawj uas yog ib nrab kev lag luam thiab ib nrab ntawm lub cev. Nws kis tau lub teeb ze rau qib iav, hnyav li ib nrab li ntau, thiab shrugs tawm cuam tshuam uas yuav tawg iav los yog tawg acrylic. Cov nuj nqis ntawm kev lag luam glazing ib txwm muab tso rau nws qhov kev tiv thaiv nyob ze 250 npaug ntawm iav thiab txog 30 npaug ntawm cov cam khwb cia acrylic. Rau ib tus kws tsim vaj tsev chasing nruab hnub nrig yam tsis muaj qhov tuag load thiab tawg kev pheej hmoo ntawm glazing, extruded polycarbonate glazing profiles daws ob peb teeb meem ib zaug.

 

Qhov ntsuas ntawm qhov kev thov no tseem ceeb rau tus kws qhia txog qhov nqaim. Cov khoom siv hauv ntau lab tons hauv ib xyoos, nrog kev tsim kho thiab kev tsim kho kom muaj txiaj ntsig ntawm lub ntiaj teb polycarbonate kev lag luam tseem loj hlob mus txog qhov kawg ntawm kaum xyoo (Mordor txawj ntse), tuaj txog nrog kev txiav txim siab, zoo-cov qib kev tsim vaj tsev zoo nkauj thiab cov khoom siv ruaj khov tom qab nws tsis yog qhov tsis paub tseeb ntawm cov khoom siv hauv tsev. Rau cov polycarbonate lub tsev tsis nruj, qhov kev loj hlob yog qhov sib txawv ntawm kev qhia nrog kev ntseeg siab thiab kev qhia txog kev ntseeg.

Cov Naj Npawb Ua Tau Ua Tau Zoo Tshaj Plaws

Ib daim ntawv teev cov ntaub ntawv rau polycarbonate zoo li rov hais dua kom txog thaum koj yuav tsum tiv thaiv kev xaiv rau tus neeg saib xyuas cov qauv. Cov txiaj ntsig hauv qab no yog lub hnab ntawv ua haujlwm rau cov qib PC nruj peb extrude, tsis yog cov ntawv xov xwm. Kho lawv raws li qhov seem yuav tsum tau nyob hauv, thiab nco ntsoov tias ob txoj kab txiav txim siab ntau dua li qhov seem.

Qhov cuam tshuam, flexural{0}}modulus thiab kam rau ua tus lej yog los ntawm peb tus kheej qhov kev ntsuas qib; Thaum tshav kub kub deflection, kev pab cuam ntau yam thiab thermal expansion khiav tawm qhov tseem ceeb rau bisphenol-A polycarbonate.

Thawj kab tsim nyog ncua rau yog cua sov deflection. Ib qho polycarbonate profile tsis tau tuav nws cov duab nyob ib puag ncig 130 degree, uas suab zoo siab kom txog thaum koj tso nws ncaj qha rau lub siab - tso tawm LED lub rooj tsavxwm lossis sab hauv lub kaw lus sab qab teb -fab qhov kab noj hniav uas muaj cua nkag mus deb dua li qhov kev nyeem ntawv pom zoo. Qhov thib ob yog qhov coefficient ntawm thermal expansion, ib tus lej feem ntau tsis quav ntsej thaum nruj polycarbonate architectural profiles yog cov ncauj lus kom ntxaws. Cov khoom siv uas txav 65 mus rau 70 microns ib 'meter' ib℃tsis kam rau pinned nyob rau hauv qhov chaw, thiab lub thav duab, tsis yog lub polymer, feem ntau yog dab tsi ua ntej.

Cov qauv siv tau tsim nyog rau npe hauv ib qho kev xa tawm yog ASTM D256 rau cov duab cuam tshuam, ASTM D638 rau tensile cwj pwm, thiab UL 94 series rau flammability. Hais txog txoj kev sim es tsis yog tus lej ib puag ncig yog dab tsi cais qhov kev ntseeg siab rau extruded rigid polycarbonate profiles los ntawm daim ntawv thov.

Nyeem Ntawv Hla -Section: Los ntawm Kev Txuas Txuas mus rau Cov Npog Kho qhov muag

Daim ntawv thov drives geometry, thiab geometry drives li cas cov profile yog ua. Hauv cov txheej txheem glazing, cov H- channels tuaj yeem koom nrog cov vaj huam sib luag uas nyob ib sab thaum U-channels kaw tawm cov npoo tawm tsam dej thiab cov khib nyiab; ob leeg yog cov txheej txheem polycarbonate txuas profiles thawj zaug thiab cov khoom siv tshuaj pleev ib ce thib ob. Nyob rau hauv lub ru tsev thiab canopies, corrugated thiab sawv- seam seem nqa lawv tus kheej loads thiab tso dej, thaum cov khoom tiaj tus thiab embossed seem yog xaiv qhov twg cua, lawg, thiab daus xav kom muaj zog, tsawg cellular cross-section. Cov ntaub ntawv kawg ntawd yog thaj chaw pebtsim polycarbonate profilesraug txiav rau.

Teeb pom kev zoo yog lwm qhov siab - tus nqi hauv tsev rau cov khoom siv, thiab nws nug txog qhov sib txawv ntawm qhov profile nkaus. Ntawm no cov extruded polycarbonate teeb pom kev zoo profile yog ib qho khoom siv kho qhov muag: lub diffuser uas yuav tsum tau nthuav tawm ib qho LED sawb mus rau hauv ib txoj kab ntawm lub teeb uas tsis pom qhov kub thiab txias, los yog lub lens tuned rau ib lub kaum ntse ntse. Tau txais txoj cai diffuser yog nyob ntawm phab ntsa- thickness uniformity thiab deg tiav los ntawm qhov tuag, tsis yog ntawm cov khoom loj, uas yog qhov pebteeb pom kev zoo polycarbonate profiles rau LED sawbyog tuned xa.

Co-extrusion yog qhov kev hloov pauv ntawm kev lag luam. Ib qho co-extruded polycarbonate profile tuaj yeem sib txuas cov txheej txheej sab nraud nrog cov ntsiab lus meej lossis cov qauv, thiab nce ntxiv nws hloov cov vaj tsev nyob sab nraud. Swapping ib tug txhuas puag rau ib tug yas ib yuag poob, tso cai ntau intricate snap geometry, thiab txo tus nqi tiav ntawm lub luminaire, uas yog vim li cas linear - teeb pom kev zoo OEMs tau tsiv mus rauco-extruded LED teeb pom kev zoo profilessai sai.

Khoom, Multiwall, los yog Acrylic: Tsis txhob muab lawv cov nqi

Cov cwj pwm phem tshaj plaws hauv kev qhia tshwj xeeb yog kho cov khoom siv polycarbonate, multiwall polycarbonate, thiab acrylic ua tib yam khoom ntawm peb nqe lus. Lawv tsis hloov pauv tau, thiab xaiv qhov pheej yig tshaj plaws uas "zoo meej txaus" yog li cas cov phiaj xwm xaus nrog lub teeb daj, cov kab tawg, lossis lub rooj sib tham glazing uas tsis tau muaj qhov kev ntsuam xyuas cuam tshuam pib nrog. Txhua yam khoom raug tsim los daws cov teeb meem sib txawv, yog li cov lus teb ncaj ncees rau cov lus nug ntawm polycarbonate vs acrylic profiles yog tias nws nyob ntawm cov ntaub ntawv thauj khoom, txawm tias tsis nyob hauv tes -waving txoj kev uas kab lus feem ntau yog siv. Ntawm no yog qhov sib cais uas tseem ceeb.

Qhov scenario cais yog qhov uas qhov no yuav ua tau. Rau kev ua phem phem -cov chaw tiv thaiv kev thauj mus los lossis lub vijtsam kev nyab xeeb, cov khoom siv polycarbonate profile rau glazing yog qhov kev xaiv tiv thaiv, thiab acrylic yuav tsum tau txiav txim siab rau qhov kev xav tau ntawm ib leeg. Rau lub tsev cog khoom uas muaj cua sov los yog lub ru tsev warehouse hnub ci, lub insulating multiwall polycarbonate profile khwv tau nws qhov chaw vim yog dais - cua hlwb txiav cov cua sov hauv ib txoj kev ntawm ib daim tawv nqaij ua tsis tau. Thiab rau ib qho backlit kos npe uas tsis muaj kev cuam tshuam, acrylic lub superior nto thiab tus nqi qis yuav yeej yeej, ib rooj plaub uas ncav cuag polycarbonate yog dhau - engineering. Lub ntsiab lus yog tias qhov kev txiav txim siab sib txawv yog cov ntaub ntawv thauj khoom, tsis yog kab - tus nqi khoom, thiab txhua tus neeg muag khoom uas coj tus nqi ua ntej nug txog cov ntaub ntawv thauj khoom yog kwv yees rau koj.

Xaiv cov qeb yog qhov yooj yim. Lub thickness, tav pitch, thiab ncua uas ua tau tshem koj cov daus, cua, los yog taw tes loads nyob ntawm tus lej xwb koj qhov project muaj. Xa peb cov ntaub ntawv load tiv thaiv lubtag nrho cov ntaub ntawv thiab kam rau ua sivthiab qhov kev xaiv qeb yuav tsum tsis ua haujlwm.

Qhov Kev Ua Phem Ua Tsis Tau Ua Rau Ib Daim Ntawv Qhia

Polycarbonate tsis tshua muaj ua tsis tau vim tias cov polymer tsis muaj zog. Nws ua tsis tau vim nws tau teeb tsa zoo li yog iav, thiab cov tsos mob hauv cheeb tsam tau kwv yees txaus los txheeb los ntawm qhov ua rau.

Thermal txav yog lub taub hau ua txhaum cai. Vim tias cov khoom nthuav dav thiab sib cog lus thoob plaws nws cov kev pabcuam dav dav, cov khoom siv polycarbonate tsis ruaj khov uas ruaj khov heev tsis tuaj yeem txav mus los, thiab cov kev ntxhov siab uas raug cuam tshuam tshwm sim li hneev nti, waving, lossis tawg tawg los ntawm qhov fastener qhov. Feem ntau siv nyiaj pub dawb yog nyob ntawm qhov kev txiav txim ntawm peb mus rau tsib millimeters ntawm kev txav mus rau ib lub 'meter' ntawm qhov ntev, thiab kev khiav ntev yog txhais tau tias ntab. H-cov ntaub ntawv muaj tseeb yog li cov vaj huam sib luag tuaj yeem xaub thaum lawv nthuav dav ntau dua li sib ntaus lawv cov ncej. Ib qho ob- ' meter ' seem tuaj yeem loj hlob li ntawm 7 hli nrog tsib caug-degree kub viav vias, mus los ntawm daim duab qhia chaw installers, uas yog ntau tshaj li txaus rau buckle lub vaj huam sib luag uas tau pinned ntawm ob qho kawg. Tus lej ntawd yog txoj cai ntawm tus ntiv tes xoo, txawm li cas los xij, thiab ntawm no yog qhov sib txawv feem ntau hla: qhov nyiaj pub dawb uas koj xav tau yog nyob ntawm cov xim tsaus tshaj plaws thiab qhov kub siab tshaj plaws ntawm qhov kev khiav yuav pom, tsis yog nyob rau hnub nws tau teeb tsa, yog li qhov profile dub nyob rau sab hnub poob -fab phab ntsa xav tau kev tshem tawm ntau dua li daim duab generic implies.

Fastening yog ob tsev neeg ua tsis tiav. Kev kho qhov loj loj, hloov pauv EPDM cov tshuab ntxhua khaub ncaws, thiab txhob txwm tsis kam ua kom dhau -torque yog dab tsi ua kom cov ntaub ntawv polycarbonate extruded zoo; tsav cov screws hauv tsev zoo li cov ntawv hlau thiab cov kab nrib pleb tshwm nyob ib ncig ntawm txhua lub fastener hauv lub lis piam. Qhov thib peb yog tshuaj lom neeg: ntau cov tshuaj ntxuav txhua hnub, cov kuab tshuaj, thiab cov khoom ua kom txias ua rau ib puag ncig kev ntxhov siab tawg, ncua kev puas tsuaj uas tshwm sim hnub tom qab hauv cov chaw thauj khoom thiab yuav luag txhua zaus kuaj pom tias tsis zoo. Kev tshuaj xyuas cov neeg ua haujlwm tu thiab cov roj nplua nyeem nyob ze tiv thaiv cov polymer ua ntej kev xa khoom yog kev pov hwm pheej yig. Tsis muaj ib qho ntawm cov no yog cov tsis xws luag polymer. Lawv nthuav dav thiab tuav cov kev txiav txim siab, thiab lawv yog qhov sib txawv ntawm kaum - xyoo kev teeb tsa thiab kev hu rov qab.

Dab tsi Peb Tswj ntawm Kab Extrusion

Txhua yam saum toj no xav tias qhov profile tawm hauv lub Hoobkas rau spec, thiab qhov ntawd tsis siv neeg. Cov khoom uas tus tsim qauv tso siab rau yog teem ntau npaum li cas los ntawm cov txheej txheem extrusion raws li qib resin, uas yog vim li cas qhov tuag thiab kab teeb meem ntau npaum li cov ntaub ntawv pov thawj. Uniform phab ntsa tuab ua kom txias txawm thiab kev ntxhov siab sab hauv; radiused fab ntau dua li cov ntse ntse yooj yim cov khoom ntws thiab tshem tawm cov kev ntxhov siab; tsim nyog cov qauv thiab symmetry nres qhov seem warping thaum nws txias. Ib qho kev cai -extruded polycarbonate profile uas tau txais cov ntsiab lus tsis ncaj ncees lawm yuav ua tau raws li nws cov ntaub ntawv cov ntaub ntawv thiab tseem ua tsis tau lub rooj zaum hauv thaj teb.

 

Kev kam rau siab yog qhov uas tus extruder loj cais nws tus kheej los ntawm tus tub luam. Peb cov kab tuav lub polycarbonate extrusion profile rau kwv yees li ± 0.08 txog ± 0.20 hli, thiab peb mus txog qhov ntawd los ntawm kev qhuab qhia yaj- kub thiab txias tswj. Cov qhab ntawd yog vim li cas snaps - haum clicks tsev es tsis txhob rattling los yog splitting, thiab nws tsis yog ib yam dab tsi uas txhua txhua extruder tuav tsis tu ncua.

Huab cua yog lwm lub zog uas peb khaws cia hauv - tsev: es tsis lees txais cov xim daj, peb tsim lub UV- tiv thaiv polycarbonate profile nyob ib ncig ntawm lub hom phiaj -tsim huab cua masterbatch. Peb tus kheej LS-141 qib tau tawm los ntawm kev rov ua dua qhov kev sim sib piv nrog cov neeg siv khoom, tshwj xeeb los txhawb nqa UV thiab huab cua kev ua haujlwm ntawm kev ua haujlwm raug.

 

Ntawm tus nqi thiab lub sijhawm ua haujlwm, cov lus nug txog kev yuav khoom tiag tiag nug ua ntej, qhov kev txiav txim siab ncaj ncees yog qhov no. Cov tuag yog ib qho - lub sij hawm cov cuab yeej cuab tam uas amortises tshaj qhov khiav, yog li tus nqi ib - meter ntog raws li ntim nce, thaum seem complexity, phab ntsa thickness, thiab seb ib feem yog ib zaug - los yog co-extruded txav tus naj npawb ntau tshaj li cov resin ua. Vim tias peb txiav cov kev cai tuag nyob rau hauv li 72 teev, cov hlau lead -lub sij hawm hwm cov neeg tuav rau ntawm kev cai ua haujlwm feem ntau ploj mus. Yog hais tias lub mechanics ntawm yuav ua li cas cov seem yog tsis paub,cov txheej txheem yas extrusiontsim nyog nyeem nrog rau qhov no.

Tig ib tug Hla-Nqe mus ua ib feem

Qhov dhau los ntawm -kab ntawm txhua yam ntawm no yog tias cov khoom siv polycarbonate tsis yog cov khoom koj xaj los ntawm 'meter'. Nws yog qhov kev txiav txim siab tshwj xeeb qhov twg cov ntaub ntawv thauj khoom xaiv cov qib, kev nthuav dav tiv thaiv qhov tsis ua haujlwm, thiab lub extruder tuav lub siab ntev uas ua rau tag nrho cov khoom sib dhos. Tau txais peb txoj cai thiab cov khoom siv ua raws li nws tau cog lus rau ib xyoo caum lossis ntau dua. Yog tias koj twb muaj daim duab kos lossis txawm tias cov duab kos duab ntxhib ntawm ntu koj xav tau, txoj kev nrawm tshaj plaws rau cov lus teb tiag tiag yogxa tus ntoo khaub lig-section rau kev cai extrusion quotethiab kom nws tshuaj xyuas cov ntaub ntawv thauj khoom ntau dua li daim ntawv teev nqi.
