Distinguishing txoj kev ntawm cov xim ntawv polyvinyl chloride ua los ntawm blister tshuab

Raws li txoj kev tau txais vinyl chloride monomer, nws tuaj yeem muab faib ua calcium carbide method, ethylene method thiab imported (EDC, VCM) monomer method (ethylene method and the imported monomer method is commonly referred to as the ethylene method). Raws li cov txheej txheem polymerization, PVC tuaj yeem muab faib ua plaub pawg: txoj kev tshem tawm PVC, emulsion method PVC, bulk method PVC, tov method PVC. Suspension-processed polyvinyl chloride yog ib qho kev tso zis ntau tshaj plaws, suav txog li 80 feem pua ​​​​ntawm tag nrho cov zis ntawm PVC. Suspension PVC muab faib ua rau tus qauv raws li qhov tseeb viscosity: XS-1, XS-2...XS-6; XJ-1, XJ-2..., XJ-6. Lub ntsiab lus ntawm txhua tsab ntawv hauv tus qauv: X-txheej txheem txheej txheem; S-loj hom; J-tight hom.
