Dab tsi yog qhov kev txhaj tshuaj kub ntawm cov nplaim-retardant PC yas? Nws puas tuaj yeem txhaj tshuaj molded?
Lub ntiajteb txawj nqus tshwj xeeb ntawm nplaim taws retardant PC: 1. 110-120 degree rau 8 teev, nws tuaj yeem siv tau ntev hauv qab -60 ~ 120 degree . Cov khoom muaj kev cuam tshuam lub zog, zoo seem stability, tsis muaj xim thiab pob tshab, xim zoo, zoo hluav taws xob rwb thaiv tsev, corrosion kuj thiab hnav tsis kam, tab sis nws muaj tsis zoo nws tus kheej lubrication, kev nyuaj siab tawg nyiam, yooj yim hydrolysis ntawm kub, thiab tsis zoo compatibility nrog rau lwm yam. resins. Haum rau kev ua cov cuab yeej me me, insulating pob tshab qhov chaw thiab qhov cuam tshuam resistant.
Kev ua tau zoo ntawm PC yas raw khoom ntawm kev txhaj tshuaj kub:
1. Cov khoom siv amorphous, zoo thermal stability, dav molding kub ntau yam thiab tsis zoo fluidity. Kev nqus dej yog me me, tab sis nws yog rhiab rau dej thiab yuav tsum tau qhuav. Lub molding shrinkage yog me me, uas yog yooj yim rau melting cracking thiab kev nyuaj siab concentration. Yog li ntawd, molding tej yam kev mob yuav tsum nruj me ntsis tswj, thiab cov yas qhov chaw yuav tsum tau annealed.
2. Heated extension nozzle yuav tsum tau siv rau cov yas qhov chaw uas muaj melting kub thiab siab viscosity, uas yog ntau tshaj 200g.
3. Qhov txias txias yog ceev ceev, thiab pwm pouring system yog raws li lub hauv paus ntsiab lus ntawm tuab thiab luv. Nws yog qhov tsim nyog los teeb lub txias txias kom zoo, lub rooj vag yuav tsum loj dua, thiab cov pwm yuav tsum tau rhuab.
4. Yog tias cov khoom siv kub qis dhau, nws yuav ua rau cov khoom tsis txaus, cov khoom yas yog Matt, thiab yog tias cov khoom kub siab dhau lawm, nws yooj yim kom dhau thiab cov khoom yas blister. Thaum cov pwm kub tsis tshua muaj, qhov shrinkage, elongation thiab cuam tshuam lub zog yog siab, thiab khoov, compression thiab tensile zog yog tsawg. Thaum cov pwm kub siab tshaj 120 degree, cov khoom yas txias maj mam thiab yooj yim rau deform thiab lo rau pwm.
1, Txheej txheem yam ntxwv I
1. Lub fluidity ntawm cov tshuaj yog rhiab rau kub thiab insensitive rau siab. Nws nyob ze rau Newtonian kua thiab belongs rau viscosity kub rhiab hom.
2. Nws tuaj yeem suav tau tias yog amorphous polymer, tsis muaj qhov pom tseeb melting point, siab yaj viscosity thiab nyuaj txaus. Nws yog qhov yuav tsum tau ua kom cov pwm khiav lub rooj vag luv luv thiab tuab kom txo qis kev poob siab, thiab tib lub sijhawm, yuav tsum tau txhaj tshuaj ntau dua.
3. Nyob rau hauv qhov kub thiab txias, cov resin yog ib qho yooj yim rau hydrolyze, thiab nyiaj hlau yog tsim nyob rau hauv cov khoom. Cov resin yuav tsum tau qhuav ua ntej ua, kom cov dej ntsiab lus qis dua 0.02 feem pua . Thaum lub sij hawm ua cov txheej txheem, yuav tsum tau them nyiaj mloog mus rau lub rwb thaiv tsev ntawm cov resin los tiv thaiv cov resin los ntawm absorbing noo noo dua.
4. Cov khoom lag luam yooj yim tawg, yog li ua tib zoo tshem tawm cov kev ntxhov siab sab hauv ntawm cov khoom thaum lub sij hawm ua, xws li nce pwm kub thiab tom qab kho cov khoom.
Txheej txheem yam ntxwv II
1. Lub molding shrinkage ntawm cov khoom yog 0.5-0.7 feem pua , thiab cov kev taw qhia ntws yog ib txwm ua raws li txoj cai ntsug.
Lub fluidity ntawm cov tshuaj muaj feem xyuam rau cov phab ntsa thickness ntawm cov khoom. Qhov sib piv ntev ntawm cov tshuaj PC yog 80-100: 1, thiab qhov tuab ntawm cov khoom feem ntau tsis tsawg dua 1 hli, feem ntau ntawm 1.5-5mm;
2. Rau cov khoom uas muaj phab ntsa thickness tsawg dua 3 hli thiab ntws ntev tsawg dua 250mm, nws raug tso cai txais yuav taw tes qhov rooj txoj kab uas hla ntawm 0.8-1mm;
3. Qhov tob ntawm qhov tso pa tawm yog tsawg dua 0.03mm;
4. Txhawm rau pab cov pwm ua kom zoo, cov pwm tuaj yeem xaiv tau ntawm 120-0 degree ;
2, Yuav tsum tau ua cov khoom siv
1. Cov cuab yeej muaj peev xwm: nws yuav tsum tau txhaj tshuaj ntim ntawm cov khoom yuav tsum tsis pub tshaj 60-70 feem pua ntawm nominal ntim ntawm lub tshuab txhaj tshuaj molding
2. Ntsia hlau: qhov ntev txoj kab uas hla piv l/d ntawm cov ntsia hlau yog 15-20, thiab compression piv yog 2-3.
3. Lub ntsuas kub tswj: qhov ntsuas kub tswj yuav tsum tau hloov kho dawb ntawm 400 degree -0 degree .
4. Nozzle: vim qhov dej tsis zoo ntawm PC, lub qhov taub ntawm lub nozzle yog 3-6mm, qhov ntev yog 12-25mm, thiab yog nruab nrog lub tshuab cua sov cais.
