Raws li lub npe qhia, cov tshuaj nplaum polyvinyl chloride (PVC) yog siv rau hauv daim ntawv ntawm cov tshuaj nplaum. Cov neeg feem ntau hu cov tshuaj nplaum no ua cov tshuaj nplaum yas. Nws yog cov kua tshwj xeeb ntawm PVC yas hauv lub xeev tsis tau ua tiav. Cov tshuaj nplaum feem ntau tau los ntawm emulsion thiab micro suspension.
Vim nws qhov me me, PVC paste resin zoo li hmoov talc thiab tsis muaj fluidity. PVC paste resin yog sib xyaw nrog plasticizer thiab do kom ua ib qho kev ncua ruaj khov, uas yog, PVC paste, lossis PVC plasticized paste thiab PVC sol, uas yog siv los ua cov khoom kawg. Hauv cov txheej txheem ua paste, ntau yam fillers, diluents, heat stabilizers, foaming agents thiab lub teeb stabilizers raug ntxiv raws li qhov xav tau ntawm cov khoom sib txawv.
Kev txhim kho ntawm kev lag luam PVC paste resin muab ib hom khoom siv kua tshiab uas tsuas yog cua sov xwb thiaj li hloov mus ua cov khoom PVC. Cov khoom siv kua muaj qhov zoo ntawm kev teeb tsa yooj yim, kev ua haujlwm ruaj khov, kev tswj yooj yim, kev siv yooj yim, kev ua haujlwm zoo heev, kev ruaj khov tshuaj lom neeg zoo, lub zog kho tshuab, xim yooj yim, thiab lwm yam. Yog li ntawd, nws yog siv dav hauv kev tsim cov tawv nqaij cuav, cov khoom ua si enamel, cov cim lag luam mos, cov ntawv ntsa, cov xim pleev xim, cov yas ua npuas dej, thiab lwm yam.
