China Zhongtai PVC utomoni katundu
China Zhongtai PVC utomoni katundu,
pvc utomoni kwa chitoliro, PVC utomoni kwa mbiri,
Polyvinyl chloride (PVC) ndiye woyambitsa wa peroxides ndi azo compounds mu vinyl chloride monomer (VCM).Kapena pansi pa zochita za kuwala ndi kutentha malinga ndi limagwirira ufulu kwakukulu polymerization polymerization polima.Vinyl chloride homopolymer ndi vinyl chloride copolymer amatchedwa vinyl chloride resin.
PVC inali pulasitiki yayikulu kwambiri padziko lonse lapansi ndipo imagwiritsidwa ntchito kwambiri.Amagwiritsidwa ntchito kwambiri muzomangamanga, zinthu zamafakitale, zofunikira zatsiku ndi tsiku, zikopa zapansi, njerwa zapansi, zikopa zopanga, chitoliro, waya ndi chingwe, filimu yonyamula, botolo, thovu, zinthu zosindikizira, CHIKWANGWANI ndi zina zotero.ntchito zake zazikulu ndi PVC mbiri, PVC chitoliro, PVC filimu, PVCPVC zolimba ndi mbale, PVC ambiri zofewa mankhwala, PVC ma CD zipangizo, PVC wallboard ndi pansi, PVC ogula katundu, PVC ❖ kuyanika mankhwala, PVC thovu mankhwala, PVC mandala pepala, etc. .
PVC yokhala ndi zida zabwino kwambiri zamakina, mankhwala monga kukana kwa asidi ndi dzimbiri zamchere, zachilengedwe kuchokera kuzimitsa moto wozimitsa moto, otsika kutentha kutengera koyenefi, kuteteza kutentha kumachepetsa phokoso, zinthu zoteteza chilengedwe, zitha kukhala zabwino kwambiri, monga kusinthidwa kwa thupi ndi mankhwala kwakhala chinthu chofunikira panyumba yobiriwira, msika womanga uinjiniya, mpaka masauzande ambiri, monga momwe anthu ochulukira amadziwira ndikuzindikiridwa.Pakali pano, gulu la zhongtai monga loyamba, atatu apamwamba kwambiri padziko lonse lapansi ogulitsa PVC zoweta, apanga kukula kwa matani 2.3 miliyoni a polyvinyl kolorayidi (PVC) utomoni, kulimbikitsa mwamphamvu kugwiritsa ntchito mankhwala a PVC apamwamba mu zonse. moyo, ndi dziko wobiriwira chitukuko ndi katundu mbali kukhazikitsa ndi kuchita kukonzanso, ndi yaitali thanzi chitukuko cha udindo makampani ndi chimbalangondo.Pepalali makamaka limayambitsa PVC kuchokera kuzinthu zisanu, monga mawu oyamba, magulu, kaphatikizidwe, kusinthidwa ndi kugwiritsa ntchito.
