Tuam Tshoj PVC cob
Tuam Tshoj PVC cob,
Khoom nthuav dav
Polyvinyl chloride yog siab molecular compounds 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, cov tshuaj tiv thaiv kab mob, muaj pes tsawg leeg reactant, 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.
Tuam Tshoj PVC resin Hom: JUNZHENG, LG BOHAI, BEIYUAN, SINOPEC, ERDOS, ELION, TIANYE, YOUNGLIGHT, DAGU CHEMICAL
