PC yas molding rau cov neeg mob
PC tuaj yeem txhaj tshuaj, extrusion, molding, tshuab moulding, kub sib sau, luam ntawv, tsevneeg, txheej thiab ua haujlwm. Txoj kev ua tseem ceeb tshaj plaws yog kev txhaj tshuaj molding.Qhov khoom yuav tsum yog pre-dried ua ntej kev sib sau, thiab cov dej noo noo yuav tsum tsawg dua 0.02%. Kev ua cov dej tsawg tsawg ntawm qhov kub siab yuav ua kom cov khoom tsim ua xim dawb, nyiaj hlau thiab npuas. PC muaj ib qho kev muaj peev xwm yuam kev siab yeem deformation ntawm chav tsev kub. Qhov teeb meem toughness yog siab, txias txias, txias txias, txias yob siab thiab lwm cov txheej txheem txias tuaj yeem nqa tawm.Tus molecular nyhav ntawm PC rau extrusion yuav tsum ntau tshaj li ntawm 30,000, yuav tsum tau siv lub taub me me, qhov sib npaug ntawm qhov sib npaug yog 1:18 txog 24, qhov sib txuam yuam yog 1: 2.5, extrusion tshuab molding yuav siv tau, txhaj tshuaj - tshuab, txhaj tshuaj - rub tawm tshuab moulding zoo siab , pob tshab npog siab heev.Yuav muaj ntau hom poom poom, xws li high viscosity ntawm PC yaj (machinability) thiab kev nyuab siab tawg ntawm cov khoom. Cov ntaub ntawv hauv PC los sis cov qauv sib txawv los ua kom cov khoom siv zoo dua qub kom zoo dua qub.Yuav muaj PC / ABS alloy, PC / ASA alloy, PC / PBT alloy, PC / PET alloy, PC / PET / elastomer blend, PC, PC / MBS blend / PTFE alloy, PC / PA alloy, etc., muaj ob hom kev kawm zoo, thiab nqi qis dua, xws li PC / ABS alloy, lub hauv paus loj rau lub siab kub hnyiab, zoo toughness thiab feem zog, siab zog, nplaim hluavtaws , TSIS tuaj yeem txhim kho qhov kev txiav txim siab thiab pom kev zoo, txo qhov ceev.Properties ntawm polycarbonate thiab molding tsis qhia nyob rau hauv lub rooj: (rau kev siv xwb) qhov sib txawv ntawm 1.18 ~ 1.20 pwm kub 50 ~ 80 shrinkage ratio ntawm 0.5 ~ 0.8 txhaj tshuaj tiv thaiv kom txias ntawm 80 ~ 130 ° C / 110 ~ 120 tsis muaj sij hawm txhaj tshuaj ntawm 20 ~ 90 zaug / h 8 ~ 10 0 ~ 5 khoom kub thawm / kub siab tom qab lub sijhawm 210 ~ 240 ° C cua txias sijhawm 20 ~ 40 ~ 190 90 sab hnub poob ntawm 230 ~ 280 tag nrho cov voj voog hauv 240 ~ 285 kev sib tw hauv kaujruam 28Qhov no zle kub yog 240 ~ 250 siv lub ntswg hom ntaus kis las
