Cov yeeb yaj kiab PVC siv dav hauv kev ntim khoom, kev lag luam thiab cov neeg siv khoom, vim lawv pheej yig, yooj yim plasticity, tiv taus acid/alkali thiab yooj yim ua tiav theem ob. Txawm li cas los xij, lawv qhov tsis zoo ntawm huab cua yog qhov tsis zoo, uas txwv tsis pub siv ntev hauv sab nraum zoov lossis chaw nyob hnyav thiab ua rau cov yeeb yaj kiab PVC tiv taus huab cua tseem ceeb rau cov tuam txhab tsim khoom.
Cov yeeb yaj kiab PVC raug faib ua ntau pawg los ntawm ntau yam kev ntsuas kom ua tau raws li ntau yam kev xav tau ntawm kev lag luam, kom ntseeg tau tias siv tau raws li qhov xav tau. Los ntawm cov ntsiab lus ntawm cov khoom siv yas, muaj cov yeeb yaj kiab ywj pheej (30% -50% cov khoom siv yas, khoov tau) thiab cov yeeb yaj kiab nruj (<5% cov khoom siv yas, tawv). Los ntawm txoj kev ua tiav, lawv suav nrog cov yeeb yaj kiab cua (tuab sib xws) thiab cov yeeb yaj kiab calendered (qhov chaw du). Los ntawm kev ua haujlwm, muaj cov pob tshab, xim thiab cov hom phiaj tshwj xeeb xws li cov yeeb yaj kiab tiv taus hluav taws thiab cov yeeb yaj kiab tiv thaiv hluav taws xob, txhua tus hloov kho rau cov xwm txheej siv tshwj xeeb.
Lawv daim ntawv thov siv tau rau ntau qhov chaw uas muaj kev xav tau sib txawv: cov zaj duab xis yooj ywm rau kev ntim khoom noj (xav tau cov zaj duab xis PVC qib khoom noj khoom haus ruaj khov), cov tsho tiv nag thiab cov khoom ua si; cov zaj duab xis ruaj khov rau kev kho kom zoo nkauj rooj tog thiab kev tiv thaiv hluav taws xob; cov zaj duab xis tshwj xeeb rau kev cog qoob loo ua liaj ua teb (xav tau kev tiv thaiv UV ntev) thiab kev rwb thaiv tsev hauv kev lag luam. Txhua qhov xwm txheej ntawm daim ntawv thov muaj cov kev xav tau kev ua tau zoo tshwj xeeb, tshwj xeeb tshaj yog rau kev tiv taus cua sov thiab huab cua ntawm cov zaj duab xis PVC.
Cov khoom siv PVC zoo tshaj plawsyog qhov tseem ceeb heev rau kev daws cov teeb meem no, vim tias PVC ntshiab yooj yim lwj thaum kub ua haujlwm (piv txwv li, extrusion, blown film). Kev lwj no ua rau muaj kev hloov pauv, brittleness, lossis txawm tias zaj duab xis tawg thaum lub sijhawm tsim khoom, uas tsis tsuas yog cuam tshuam rau cov khoom zoo xwb tab sis kuj ua rau cov nqi tsim khoom nce ntxiv thiab cuam tshuam rau cov txheej txheem tsim khoom. Qhov no ua rau kev ruaj khov ntawm kev ua zaj duab xis PVC yog qhov kev txhawj xeeb tseem ceeb rau cov tuam txhab.
Cov stabilizers TopJoymuab cov kev daws teeb meem rau cov teeb meem no, ua kom cov yeeb yaj kiab PVC tiv taus cua sov thiab huab cua thiab txo cov kev pheej hmoo ntawm kev lwj. Lawv tiv thaiv kev lwj ntawm PVC, ua kom cov txheej txheem du, thiab ua tau raws li cov kev xav tau tshwj xeeb ntawm ntau hom yeeb yaj kiab. Rau cov chaw tsim khoom uas nrhiav kev txhim khu kev qhaPVC zaj duab xis stabilizercov kev daws teeb meem, TopJoy txoj kev txhawb nqa kev tshaj lij pab xa cov khoom zoo rau ntau yam kev siv, txhim kho kev sib tw ua lag luam.
