Tuam Tshoj Zhongtai PVC resin tsum
Tuam Tshoj Zhongtai PVC Resin tsum,
pvc cob rau cov kav dej, PVC cob rau profile,
Polyvinyl chloride (PVC) yog tus pib ntawm peroxides thiab azo tebchaw hauv vinyl chloride monomer (VCM).Los yog nyob rau hauv qhov kev txiav txim ntawm lub teeb thiab cua sov raws li lub mechanism ntawm dawb radical polymerization polymerization polymer.Vinyl chloride homopolymer thiab vinyl chloride copolymer yog hu ua vinyl chloride resin.
PVC siv los ua cov yas loj tshaj plaws hauv ntiaj teb thiab tau siv dav.Nws yog dav siv hauv cov khoom siv hauv tsev, cov khoom lag luam, cov khoom siv niaj hnub, cov tawv tawv hauv pem teb, hauv pem teb cib, tawv tawv, yeeb nkab, hlau thiab cable, ntim zaj duab xis, lub raj mis, cov khoom siv foaming, sealing khoom, fiber ntau thiab lwm yam.Nws cov khoom siv tseem ceeb yog PVC profile, PVC yeeb nkab, PVC zaj duab xis, PVCPVC nyuaj khoom thiab phaj, PVC cov khoom muag muag, PVC ntim cov ntaub ntawv, PVC phab ntsa thiab pem teb, PVC cov khoom siv, PVC txheej khoom, PVC ua npuas ncauj khoom, PVC pob tshab ntawv, thiab lwm yam. .
PVC nrog cov khoom siv zoo heev, cov khoom siv tshuaj lom neeg xws li tiv thaiv cov kua qaub thiab alkali corrosion, ntuj tsim los ntawm tus kheej tua hluav taws retardant kev ua tau zoo, tsis tshua muaj hluav taws kub hloov coefficient, txuag hluav taws xob suab rwb thaiv tsev suab nrov txo, cov khoom ntawm kev tiv thaiv ib puag ncig, tuaj yeem ua haujlwm zoo, xws li Kev hloov kho lub cev thiab tshuaj lom neeg tau dhau los ua cov khoom tseem ceeb ntawm lub tsev ntsuab, kev tsim kho vaj tse, kev lag luam hauv ntau txhiab tus neeg, raws li ntau thiab ntau tus neeg paub thiab lees paub.Tam sim no, zhongtai pab pawg yog thawj, lub ntiaj teb no sab saum toj peb nyob rau hauv lub domestic PVC ntau lawm cov neeg muag khoom, tau tsim lub teev ntawm txhua xyoo tso zis ntawm 2.3 lab tons ntawm polyvinyl chloride (PVC) resin, vigorously txhawb daim ntawv thov ntawm PVC cov khoom ua tau zoo nyob rau hauv tag nrho cov. taug kev ntawm lub neej, yog lub teb chaws txoj kev loj hlob ntsuab thiab muab sab rau siv thiab ua cov kev hloov kho, kuj yog ib tug ntev lub sij hawm noj qab haus huv txoj kev loj hlob ntawm kev lag luam lub luag hauj lwm thiab dais.Daim ntawv no tsuas yog qhia txog PVC los ntawm tsib yam, xws li kev taw qhia, kev faib tawm, txheej txheem synthesis, hloov kho thiab daim ntawv thov.
