Zipangizo zopangira malata apawiri-khoma molimba PVC chitoliro
Zipangizo zopangira malata apawiri-khoma molimba PVC chitoliro,
Zopangira kupanga malata wapawiri-khoma PVC chitoliro,
Polyvinyl Chloride (PVC) ndi mzere wa thermoplastic utomoni wopangidwa ndi polymerization wa vinyl chloride monomer.Chifukwa cha kusiyana kwa zipangizo, pali njira ziwiri za synthesizing vinilu kolorayidi monomer kashiamu carbide ndondomeko ndi mafuta ndondomeko.Sinopec PVC itengera njira ziwiri zoyimitsidwa, motsatana kuchokera ku Japan Shin-Etsu Chemical Company ndi American Oxy Vinyls Company.Chogulitsacho chili ndi kukana kwa dzimbiri kwamankhwala, katundu wabwino kwambiri wamagetsi wamagetsi komanso kukhazikika kwamankhwala abwino.Pokhala ndi klorini wambiri, zinthuzo zimakhala ndi mphamvu zochepetsera moto komanso zozimitsa zokha.PVC ndi yosavuta pokonza ndi extrusion, jekeseni akamaumba, calendering, kuwomba akamaumba, compressing, kuponya akamaumba ndi akamaumba matenthedwe, etc.
Kugwiritsa ntchito
PVC ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi thermoplastic resins.Itha kugwiritsidwa ntchito kupanga zinthu zolimba kwambiri komanso zolimba, monga mapaipi ndi zokokera, zitseko zojambulidwa, mazenera ndi mapepala onyamula.
Ikhozanso kupanga zinthu zofewa, monga mafilimu, mapepala, mawaya amagetsi ndi zingwe, mapepala apansi ndi zikopa zopangira, powonjezera mapulasitiki.

Zopangira zomwe zimagwiritsidwa ntchito popanga chitoliro cholimba cha PVC chakonzedwa kuchokera
PVC (100 pts.wt.),
trisalt (6.4-6.8 pts.wt.),
