Polyvinyl chloride (PVC) paste resin raws li lub npe qhia yog tias cov resin no feem ntau yog siv rau hauv daim ntawv muab tshuaj. Cov neeg feem ntau hu qhov muab tshuaj txhuam no plasticized paste. Nws yog ib hom kua tshwj xeeb ntawm PVC yas nyob rau hauv lub xeev unprocessed. Paste resins feem ntau tau los ntawm emulsion thiab micro suspension.
Vim nws qhov loj me me, PVC paste resin zoo li talc hmoov thiab tsis muaj fluidity. PVC paste resin yog tov nrog plasticizer thiab stirred los tsim ib tug ruaj khov ncua kev kawm ntawv, uas yog, PVC muab tshuaj txhuam, los yog PVC yas muab tshuaj txhuam thiab PVC sol, uas yog siv los ua txheej txheem rau hauv cov khoom zaum kawg. Nyob rau hauv cov txheej txheem muab tshuaj txhuam, ntau yam fillers, diluents, heat stabilizers, foaming agents thiab light stabilizers yog ntxiv raws li qhov xav tau ntawm cov khoom sib txawv.
Kev tsim kho ntawm PVC paste resin kev lag luam muab ib hom tshiab ntawm cov khoom ua kua uas tuaj yeem hloov mus rau hauv cov khoom siv PVC tsuas yog los ntawm cua sov. Cov khoom siv ua kua muaj qhov zoo ntawm kev teeb tsa yooj yim, kev ua haujlwm ruaj khov, tswj tau yooj yim, siv yooj yim, cov khoom lag luam zoo, kev ruaj ntseg tshuaj zoo, qee yam muaj zog, xim yooj yim, thiab lwm yam. Yog li ntawd, nws yog dav siv hauv kev tsim cov tawv tawv, enamel. cov khoom ua si, cov cim lag luam muag muag, cov ntawv ntsa, xim pleev xim, foamed plastics, thiab lwm yam.
