Polyvinyl Chloride (PVC) utomoni wa chitoliro
Polyvinyl Chloride (PVC) utomoni wa chitoliro,
PVC kwa chitoliro cha ngalande, PVC Pipe Raw Material, PVC utomoni kwa Hose, PVC utomoni wothirira,
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.

Polyvinyl Chloride (PVC) ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi thermoplastic zomwe zimapezeka m'mafakitale ambiri.Mapaipi a PVC amawonetsa mawonekedwe apadera komanso osasinthika okhala ndi zida zofanana zomwe zimapangitsa kuti ikhale chisankho chokondedwa cha opanga ndi nyumba zokhazikika.Imalimbana kwambiri ndi ma acid, alkalis, mowa, ndi zina zambiri zowononga.Makina a PVC ndi opepuka, osinthika komanso olimba, ndipo amapereka kukana kwa dzimbiri kwapadera.Chifukwa cha izi ndi zina zamtengo wapamwamba wopangidwa ndi thermoplastic, ndalama zomwe zitha kupezeka pakuyika koyambirira ndi kupitilizabe kukonzanso ndizokwera.PVC chitoliro ndi abwino ntchito zambiri kuphatikizapo kugawa mankhwala ndi ngalande, madzi ndi zinyalala mankhwala, mipope utumiki, kachitidwe ulimi wothirira, kusonkhanitsa zinyalala ndi ntchito zina zambiri mafakitale zokhudza kutengerapo dzimbiri madzimadzi.Kupanikizika kumasiyana malinga ndi ndandanda, kukula kwa mapaipi ndi kutentha.
