Lisebelisoa tse tala bakeng sa ho lokisa peipi ea PVC e thata ea marako a mabeli
Lisebelisoa tse tala bakeng sa ho lokisa peipi ea PVC e thata ea marako a mabeli,
Lintho tse tala bakeng sa ho hlahisa peipi ea PVC e entsoeng ka masenke a mabeli,
Polyvinyl Chloride (PVC) ke resin ea thermoplastic e melang e hlahisoang ke polymerization ea vinyl chloride monomer.Ka lebaka la phapang ea lisebelisoa tse tala, ho na le mekhoa e 'meli ea ho kopanya vinyl chloride monomer calcium carbide process le petroleum process.Sinopec PVC e amohela mekhoa e 'meli ea ho emisoa, ka ho latellana ho tsoa ho Japanese Shin-Etsu Chemical Company le American Oxy Vinyls Company.Sehlahisoa se na le khanyetso e ntle ea ho senya lik'hemik'hale, thepa e ntle ea ho kenya motlakase le botsitso bo botle ba lik'hemik'hale.Ka lintho tse ngata tsa chlorine, thepa e na le ts'ebetso e ntle ea ho thibela mollo le thepa ea ho itima.PVC e bonolo ho e sebetsa ka extrusion, ho bopa ka ente, calendering, ho bopa ho otla, ho hatella, ho bopa le ho bopa ka mocheso, joalo-joalo.
Kopo
PVC ke e 'ngoe ea li-resin tsa thermoplastic tse sebelisoang haholo.E ka sebelisoa ho etsa lihlahisoa tse nang le boima bo phahameng le matla, joalo ka liphaephe le li-fittings, mamati a profild, lifensetere le lipampiri tsa ho paka.
E ka boela ea etsa lihlahisoa tse bonolo, tse kang lifilimi, maqephe, lithapo tsa motlakase le lithapo, liboto tsa fatše le letlalo la maiketsetso, ka ho phaella ka li-plasticizers.
