Polyvinyl chloride (PVC) nplaum Resin, raws li lub npe qhia, yog tias cov resin no feem ntau yog siv rau hauv daim ntawv nplaum. Cov neeg feem ntau siv hom nplaum no ua plastisol, uas yog ib daim ntawv kua tshwj xeeb ntawm PVC yas hauv nws lub xeev tsis tau ua tiav. . Cov nplaum resins feem ntau yog npaj los ntawm emulsion thiab micro-suspension txoj kev.
Cov tshuaj nplaum polyvinyl chloride muaj qhov loj me me, thiab nws cov qauv zoo li talc, nrog rau kev tsis txav chaw. Cov tshuaj nplaum polyvinyl chloride yog sib xyaw nrog Plasticizer thiab tom qab ntawd do kom tsim tau ib qho kev ncua ruaj khov, uas tom qab ntawd ua rau PVC paste, lossis PVC plastisol, PVC sol, thiab nws yog nyob rau hauv daim ntawv no uas tib neeg siv los ua cov khoom kawg. Hauv cov txheej txheem ntawm kev ua cov tshuaj nplaum, 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 ua kom sov los ua cov khoom polyvinyl chloride. Hom khoom siv kua no yooj yim teeb tsa, ruaj khov hauv kev ua tau zoo, yooj yim tswj, yooj yim siv, zoo heev hauv kev ua tau zoo ntawm cov khoom, zoo hauv kev ruaj khov tshuaj lom neeg, muaj qee lub zog kho tshuab, yooj yim rau xim, thiab lwm yam, yog li nws yog siv dav hauv tawv dag, cov khoom ua si vinyl, cov cim lag luam mos, Kev tsim cov ntawv ntsa, xim thiab txheej, cov yas ua npuas dej, thiab lwm yam.

PVC paste resin (PVC) yog ib pawg loj ntawm polyvinyl chloride resins. Piv nrog rau cov suspension resins, nws yog cov hmoov uas yooj yim disperse. Qhov loj me ntawm cov khoom me me feem ntau yog 0.1 ~ 2.0 μm (qhov loj me ntawm cov khoom me me ntawm cov suspension resins feem ntau yog 20 ~ 200 μm). PVC paste resin tau tshawb fawb ntawm IG Farben lub Hoobkas hauv lub teb chaws Yelemees xyoo 1931, thiab kev tsim khoom lag luam tau ua tiav xyoo 1937.
Nyob rau ib nrab xyoo dhau los no, kev lag luam thoob ntiaj teb ntawm cov tshuaj pleev PVC tau tsim kho sai heev. Tshwj xeeb tshaj yog nyob rau kaum xyoo dhau los no, lub peev xwm tsim khoom thiab cov zis tau pom tias muaj kev loj hlob sai, tshwj xeeb tshaj yog nyob rau hauv Asia. Xyoo 2008, tag nrho lub peev xwm tsim khoom ntawm cov tshuaj pleev PVC yog kwv yees li 3.742 lab tons hauv ib xyoos, thiab tag nrho lub peev xwm tsim khoom hauv Asia yog kwv yees li 918,000 tons, suav txog 24.5% ntawm tag nrho lub peev xwm tsim khoom. Tuam Tshoj yog thaj chaw loj hlob sai tshaj plaws hauv kev lag luam tshuaj pleev PVC, nrog rau lub peev xwm tsim khoom suav txog li 13.4% ntawm tag nrho lub peev xwm tsim khoom thoob ntiaj teb thiab kwv yees li 57.6% ntawm tag nrho lub peev xwm tsim khoom hauv Asia. Nws yog tus tsim khoom loj tshaj plaws hauv Asia. Xyoo 2008, tag nrho cov zis ntawm cov tshuaj pleev PVC yog kwv yees li 3.09 lab tons, thiab Tuam Tshoj cov zis yog 380,000 tons, suav txog li 12.3% ntawm tag nrho cov zis hauv ntiaj teb. Lub peev xwm tsim khoom thiab cov zis yog qib thib peb hauv ntiaj teb.
