PVC yog rhiab heev rau cua sov. Thaum qhov kub nce mus txog 90 ℃, me ntsis thermal decomposition tshwm sim pib. Thaum qhov kub nce mus txog 120 ℃, cov tshuaj tiv thaiv decomposition intensifies. Tom qab cua sov ntawm 150 ℃ rau 10 feeb, PVC resin maj mam hloov los ntawm nws thawj xim dawb mus rau daj, liab, xim av, thiab dub. Kev ua haujlwm kub rau PVC kom ncav cuag lub viscous flow xeev yuav tsum siab tshaj qhov kub no. Yog li ntawd, txhawm rau ua kom PVC siv tau, ntau yam khoom siv ntxiv thiab cov khoom ntim xws li cov yas yas, cov stabilizers, lubricants, thiab lwm yam yuav tsum tau ntxiv thaum nws ua. ACR processing aids yog ib qho ntawm cov kev pabcuam tseem ceeb. Nws belongs rau qeb ntawm acrylic ua pab thiab yog ib tug copolymer ntawm methacrylate thiab acrylic ester. ACR kev pab txhawb nqa lub melting ntawm PVC ua tshuab, txhim kho lub rheological zog ntawm cov yaj, thiab cov incompatible qhov chaw nrog PVC tuaj yeem tsiv mus nyob sab nraum lub molten resin system, yog li txhim kho nws demolding kev ua tau zoo yam tsis tau nce lub zog noj ntawm cov khoom siv. Nws tuaj yeem pom tau tias ACR kev pab cuam ua haujlwm tseem ceeb hauv PVC ua tshuab.
Qhov zoo ntawm kev siv ACR kev pab cuam:
1. Nws muaj kev sib raug zoo nrog PVC cob, yog ib qho yooj yim rau disperse nyob rau hauv PVC resin, thiab yog ib qho yooj yim rau kev khiav lag luam.
2. Nws muaj cov yas yas sab hauv thiab tuaj yeem siv rau hauv cov khau ib leeg cov ntaub ntawv, cov ntaub ntawv hlau thiab cable, thiab cov ntaub ntawv mos pob tshab kom txo tau cov plasticizer siv thiab daws qhov teeb meem ntawm kev tsiv teb tsaws ntawm plasticizers.
3. Nws tuaj yeem txhim kho qhov ntsuas kub qis thiab cuam tshuam lub zog ntawm cov khoom.
4. Txhim kho qhov glossiness saum npoo ntawm cov khoom, superior rau ACR.
5. Zoo thermal stability thiab huab cua tsis kam.
6. Txo cov viscosity yaj, txo lub sij hawm plasticization, thiab nce tsev tawm los. Txhim kho qhov cuam tshuam lub zog thiab qis-kub yooj yooj yim ntawm cov khoom.
Hloov ACR hauv qhov sib npaug tuaj yeem txo qis kev siv roj nplua nyeem lossis nce kev siv cov khoom siv thaum tuav cov khoom siv, qhib txoj hauv kev tshiab rau kev txhim kho cov khoom zoo thiab txo cov nqi.
