Nyob ntawm seb lub Scope ntawm daim ntawv thov, PVC yuav tau muab faib mus rau hauv: general-lub hom phiaj PVC cob, siab polymerization degree ntawm PVC cob, tus ntoo khaub lig-txuas PVC cob. Cov kev hom PVC cob yog tsim los ntawm polymerization ntawm yas chloride monomer nyob rau hauv qhov kev txiav txim ntawm initiator; Lub siab polymerization degree PVC cob yog tus cob uas yog polymerized los ntawm kev ntxiv lub saw txoj kev loj hlob neeg sawv cev nyob rau hauv lub yas chloride monomer polymerization system. Lub crosslinking PVC cob yog ib tug cob uas yog polymerized los ntawm cov crosslinking neeg sawv cev uas muaj diene thiab alkene nyob rau hauv lub yas chloride monomer polymerization system.
Raws li cov qauv ntawm cov muab yas chloride monomer, nws yuav tsum tau muab faib mus rau hauv calcium carbide txoj kev, ethylene txoj kev thiab ntshuam (EDC, VCM) monomer qauv (nws yog txoj kev cai uas rau xa mus rau ethylene txoj kev thiab ntshuam monomer txoj kev collectively li Ethylene txujci).
Raws li polymerization txoj kev, polyvinyl tshuaj dawb yuav tsum tau muab faib ua plaub pawg: ncua kev kawm ntawv txoj kev polyvinyl tshuaj dawb, emulsion txoj kev polyvinyl tshuaj dawb, tej polyvinyl tshuaj dawb, tov txoj kev polyvinyl tshuaj dawb. Raug tshem tawm polyvinyl tshuaj dawb yog cov coob lawm ntawm ib tug tsiaj, ris rau txog 80% ntawm PVC ntau lawm. Raug tshem tawm ntawm PVC Raws li tsis viscosity ntawm rau qauv: XS-1, XS-2 ... XS-6, XJ-1, XJ-2, XJ-6. Lub ntsiab ntawm cov tsiaj ntawv nyob rau hauv tus qauv: X-ncua kev kawm ntawv txoj kev; s-lax hom; J Compact hom.
Raws li tus nqi ntawm cov plasticizer, PVC yas yog feem ntau muab faib mus rau hauv: tsis muaj plasticized PVC, Plasticizer cov ntsiab lus ntawm 0, PVC txhav, plasticizer cov ntsiab lus yog tsawg tshaj li 10%, semi-txhav PVC, plasticizer cov ntsiab lus yog $ tooj, mos PVC, plasticizer cov ntsiab lus yog $ tooj, pvc muab tshuaj txhuam yas, plasticizer cov ntsiab lus ntawm ntau tshaj 80%.
