mos PVC thiab tawv PVC
mos PVC thiab tawv PVC,
ntim, vaj huam sib luag, PVC cob rau cov khoom siv hauv tsev,
PVC yog lub ntsiab lus rau polyvinyl chloride.Resin yog ib yam khoom siv feem ntau siv hauv kev tsim cov yas thiab roj hmab.PVC resin yog cov hmoov dawb feem ntau siv los tsim cov thermoplastics.Nws yog cov khoom siv hluavtaws dav siv hauv ntiaj teb niaj hnub no.Polyvinyl chloride resin muaj cov yam ntxwv zoo xws li cov khoom siv ntau, kev tsim khoom siv technology, tus nqi qis, thiab ntau yam kev siv.Nws yog ib qho yooj yim rau txheej txheem thiab tuaj yeem ua tiav los ntawm molding, laminating, txhaj tshuaj molding, extrusion, calendering, tshuab moulding thiab lwm yam.Nrog rau lub cev zoo thiab tshuaj lom neeg, nws yog dav siv hauv kev lag luam, kev tsim kho, kev ua liaj ua teb, lub neej txhua hnub,ntim, hluav taws xob, kev siv hluav taws xob, thiab lwm yam.PVC resins feem ntau muaj tshuaj tiv thaiv siab.Nws muaj zog heev thiab tiv taus dej thiab puas.Polyvinyl chloride resin (PVC) tuaj yeem ua tiav rau hauv ntau yam khoom yas.PVC yog lub teeb yuag, pheej yig, thiab ib puag ncig tus phooj ywg plastics.Pvc Resin tuaj yeem siv rau hauv cov kav dej, qhov rais thav duab, hoses, tawv, xaim cables, khau thiab lwm yam khoom muag muag, profiles, fittings,vaj huam sib luags, txhaj tshuaj molding, khau khiab, lub raj tawv thiab cov ntaub ntawv zoo nkauj, lub raj mis, ntawv, daim ntawv teev npe, kev txhaj tshuaj nruj thiab moldings, thiab lwm yam.
Nta
PVC yog ib qho ntawm cov khoom siv thermoplastic feem ntau siv.Nws tuaj yeem siv los ua cov khoom lag luam nrog lub siab tawv thiab lub zog, xws li cov kav dej thiab fittings, profiled qhov rooj, qhov rais thiab cov ntawv ntim.Nws tseem tuaj yeem ua cov khoom muag muag, xws li cov yeeb yaj kiab, cov ntawv txheeb, cov xaim hluav taws xob thiab cov cables, cov ntaub pua tsev thiab cov tawv hluavtaws, los ntawm kev ntxiv cov yas yas
