Cov hloov pauv hloov chaw feem ntau yog siv hauv kev ua cov khoom coj los ua cov khoom siv PVC. Raws li lub hauv paus ntsiab lus ntawm elastomer toughening, qhov hloov kho feem ntau muaj xws li chlorinated polyethylene (CPE), acrylate polymer (ACR), Methyl Methacrylate Butadiene Styrene Copolymer (MBS), acrylonitrile butadiene styrene copolymer (ABS), ethylene vinyl acetate copolymer (EVA) thiab lwm yam CPE yog ib hom kev hloov kho thoob ntiaj teb, uas pheej yig thiab muaj tau.
ACR qhov hloov kho qhov hloov tau zoo heev rau kev hloov kho thiab huab cua tsis kam, thiab muaj qee yam ua haujlwm hloov kho, yog li nws muaj txoj haujlwm tseem ceeb hauv thaj tsam ntawm kev hloov kho kev hloov kho, thiab tseem yog lub ntsiab kev loj hlob ntawm PVC qhov kev hloov kho hauv ntiaj teb.
ACR zoo dua li CPE nyob rau hauv huab cua tiv thaiv thiab luster, thiab muaj cov txheej txheem ua cov khoom kub ntau dua thiab muaj kev cuam tshuam ntau dua CPE, yog li nws tau npaj hloov CPE ua cov hloov pauv PVC.
MBS yog ib qho tseem ceeb uas hloov kho rau PVC Elastomer. MBS siv feem ntau txhawm rau txhim kho qhov kev cuam tshuam ntawm cov pob tshab PVC cov khoom vim nws zoo sib xws nrog PVC thiab ze optical refractive index. Tau kawg, nws kuj tseem tuaj yeem siv hauv cov khoom lag luam PVC pob tshab.
Muaj ntau yam thiab ntau hom ntawm ABS. Tab sis nws tsuas yog ib feem ntawm PVC hloov kev cuam tshuam. ABS nrog cov roj hmab siab thiab cov qes taws feem ntau siv los ua kev hloov pauv rau PVC. ABS hloov PVC cov khoom lag luam tsis haum rau siv sab nraum zoov. Nws mas muaj cov ntaub ntawv kho kom zoo nkauj sab hauv thiab credit card cov ntaub ntawv. Kev ua tau ntawm ntau hom ntawm ABS yog qhov sib txawv, thiab qhov ntau npaum li cas kuj ua tau, feem ntau ntawm 5 ~ 15 phr.
Ib qho ntxiv, tseem muaj cov kev hloov kho xws li AMB thiab ACM hauv xyoo tsis ntev los no. Nrog kev muaj zog ntawm kev ua lag luam sib tw, kev tswj tus nqi tau dhau los thiab loj dua. Vim tias tus nqi zoo dua, cov txheej txheem paub tab thiab cov txiaj ntsig zoo dua, CPE tam sim no yog qhov kev cuam tshuam sab saum toj tshaj plaws nyob rau hauv Suav teb, uas nyuaj rau co hauv lub sijhawm luv.
