A: Cov Khoom Siv Polyvinyl chloride yog cov tshuaj molecular siab polymerized los ntawm vinyl chloride monomer (VCM) nrog cov txheej txheem raws li CH2-CHCLn, qib ntawm polymerization feem ntau yog 590-1500.In the process of re-polymerization, cuam tshuam los ntawm ntau yam xws li txheej txheem polymerization, tshuaj tiv thaiv kab mob, reactant muaj pes tsawg leeg, additives etc.it tuaj yeem tsim yim hom PVC resin kev ua tau zoo sib txawv.Raws li cov ntsiab lus seem ntawm vinyl chloride hauv polyvinyl chloride resin, tuaj yeem muab faib ua: qib kev lag luam, qib zaub mov huv thiab qib kev kho mob hauv qhov tsos, polyvinyl chloride resin yog hmoov dawb lossis pellet.
B: Daim ntawv thov Polyvinyl chloride resin yog dav siv hauv kev tsim cov polyvinyl chloride boardy leatheroid, xim thiab cov neeg ua haujlwm nplaum, tec.Xim thiab nplaum .Kev faib raws li daim ntawv thov:
1.Cov khoom siv hauv tsev: xws li UPVC tubing, UPVC kav, vaj huam sib luag thiab ntu tuav.
2. Cov khoom ntim khoom.
3. Cov khoom siv hluav taws xob: xws li cov xaim hluav taws xob, cables, cov nplaum nplaum thiab cov bolts.
4. Rooj tog thiab cov khoom siv kho kom zoo nkauj, thiab lwm yam.
5.Lwm yam: leatheroid, cov khoom siv kho mob pov tseg, tshuaj tua kab mob, thiab lwm yam.
