PVC rhiab heev rau cua sov. Thaum qhov kub txog 90 ℃, qhov kev ua kom sov me ntsis pib. Thaum qhov kub nce mus txog 120 ℃, qhov kev ua kom sov yuav nce ntxiv. Tom qab cua sov ntawm 150 ℃ rau 10 feeb, cov PVC resin maj mam hloov ntawm nws cov xim dawb qub mus rau daj, liab, xim av, thiab dub. Qhov kub ua kom PVC mus txog qhov viscous flow xeev yuav tsum siab dua qhov kub no. Yog li ntawd, txhawm rau ua kom PVC ua tau zoo, ntau yam khoom ntxiv thiab cov khoom sau xws li plasticizers, stabilizers, lubricants, thiab lwm yam yuav tsum tau ntxiv thaum lub sijhawm ua. ACR cov khoom pab ua yog ib qho ntawm cov khoom pab ua tseem ceeb. Nws yog ib feem ntawm cov khoom pab ua acrylic thiab yog ib qho copolymer ntawm methacrylate thiab acrylic ester. ACR cov khoom pab ua txhawb kev yaj ntawm PVC cov txheej txheem ua, txhim kho cov khoom rheological ntawm cov yaj, thiab cov khoom tsis sib xws nrog PVC tuaj yeem tsiv mus rau sab nraud ntawm cov roj hmab molten, yog li txhim kho nws cov kev ua haujlwm demolding yam tsis ua rau kev siv hluav taws xob ntau ntxiv ntawm cov khoom siv ua. Nws tuaj yeem pom tias ACR cov khoom pab ua lub luag haujlwm tseem ceeb hauv PVC cov txheej txheem ua.
Cov txiaj ntsig ntawm kev siv ACR cov khoom pab ua haujlwm:
1. Nws muaj kev sib raug zoo nrog PVC resin, yooj yim rau disperse hauv PVC resin, thiab yooj yim rau kev khiav lag luam.
2. Nws muaj cov yas sab hauv thiab siv tau rau hauv cov ntaub ntawv khau, cov ntaub ntawv hlau thiab cable, thiab cov ntaub ntawv pob tshab mos kom txo tau cov yas siv thiab daws qhov teeb meem ntawm kev tsiv teb tsaws chaw ntawm cov yas.
3. Nws tuaj yeem txhim kho qhov yooj ywm thiab lub zog cuam tshuam ntawm cov khoom.
4. Ua kom qhov ci ntsa iab ntawm cov khoom zoo dua li ACR.
5. Kev ruaj khov zoo thiab huab cua tsis kam.
6. Txo qhov viscosity ntawm cov yaj, ua kom lub sijhawm ua kom yas luv dua, thiab ua kom cov khoom tsim tau ntau dua. Txhim kho lub zog cuam tshuam thiab kev hloov pauv ntawm cov khoom hauv qhov kub qis.
Kev hloov ACR hauv qhov sib npaug zos tuaj yeem txo qhov kev siv roj nplua nyeem lossis nce kev siv cov khoom siv thaum tseem tswj cov khoom siv, qhib txoj hauv kev tshiab rau kev ua kom zoo dua cov khoom zoo thiab txo cov nqi.
