PVC SG-8
PVC SG-8,
chingwe ducts zopangira, PVC SG-8 ntchito kupanga mapanelo khoma,
Thermoplastic mkulu-maselo polima wopangidwa ndi kuyimitsidwa polymerization wa vinilu kolorayidi monoma.The molecular formula :- (CH2 – CHCl) n – (N: digiri ya polymerization, N= 590 ~ 1500).Ndizinthu zomwe zimagwiritsidwa ntchito kwambiri popanga pulasitiki.Ili ndi kukhazikika kwamankhwala abwino, kukana dzimbiri komanso kukana madzi.

Mapulogalamu
Polyvinyl kolorayidi utomoni ali osiyanasiyana ntchito, monga zamkati galimoto, zipangizo zokongoletsera banja, malonda kuwala bokosi, nsapato nsapato, mapaipi PVC ndi zovekera, PVC mbiri ndi payipi, PVC pepala ndi mbale, anagudubuzika filimu, zoseweretsa inflatable, mankhwala panja, PVC waya ndi chingwe, PVC yokumba zikopa, matabwa ndi pulasitiki pansi, corrugated bolodi, etc.
Kupaka
25kg thumba thumba liner ndi PE
Kufotokozera:
Maonekedwe PVC SG-8 ndi homogeneous woyera ufa, popanda kukoma ndi fungo.
Kugwiritsa ntchito PVC utomoni mtundu SG-8:
Mtundu wa resin SG-8 umagwiritsidwa ntchito popanga zomangira zokhala ndi mipanda yopyapyala, mapanelo apakhoma, ma ducts a chingwe, zinthu zolimba zomwe zimagwiritsidwa ntchito pazambiri (linoleum, zikopa zopangira, mafilimu apulasitiki, ma CD a polymer atatu-dimensional).
Njira yopangira:
Amapezeka ndi polymerization ya vinilu kolorayidi.The polymerization ikuchitika kuyimitsidwa (m'madzi chilengedwe).
Pali njira zambiri zopangira vinyl chloride kuchokera ku acetylene, ethylene dichloride, ethylene ndi ethane.Zogulitsa zathu zimangotengera kugwiritsa ntchito ethylene.
