PVC resin bakeng sa phala ea nosetso
PVC resin bakeng sa phala ea nosetso,
phala ea nosetso thepa e tala, pvc bakeng sa phala ea nosetso,
Pipe ea ho nosetsa ea PVC:
(1) Pipe ea nosetso ea PVC e na le khanyetso e ntle ea asiti, ho hanyetsa alkali le ho hanyetsa kutu, e loketseng indasteri ea lik'hemik'hale.Bokaholimo ba phala ea nosetso ea PVC bo boreleli.Ho hanyetsa mokelikeli ho nyane, 'me coefficient ea eona e thata ke 0.009 feela, e leng ka tlaase ho liphaephe tse ling.Tlas'a sekhahla se tšoanang sa phallo, bophara ba phala bo ka fokotsoa.Ho hanyetsa khatello ea metsi, ho hanyetsa khatello ea ka ntle le ho hanyetsa tšusumetso ea liphaephe tsa nosetso tsa PVC li phahame haholo, tse loketseng boenjiniere ba liphaephe tlas'a maemo a sa tšoaneng.E theko e tlase ebile e sebelisoa haholo.
(2) Peipi ea nosetso ea PVC e ka latela mokhoa oa kholo ea lijalo ho hlokomela nosetso ea sejoale-joale.Tšebeliso ea metsi ea ho nosetsa e ka khethoa ho ea ka mongobo o khethehileng oa lijalo le mobu.
(3) PVC nosetso phala ke ka ho fetisisa ka ho feletseng e ka thehiloeng litšobotsi tsa hona joale kwether ho finyella phepelo e nepahetseng ea metsi le manyolo ho motso oa lijalo mekhoa nosetso.Sena se ka fokotsa mosebetsi oa matsoho.
(4) Pipe ea nosetso ea PVC e ka tsamaisa tšebeliso e loketseng ea metsi a nosetso ho latela litlhoko tsa kholo ea lijalo, e ka netefatsang nosetso e nakong le e loketseng ea lijalo le ho rala motheo o tiileng oa ho ntlafatsa chai ea lijalo.
(5) Lipeipi tsa nosetso li sebelisoa haholo phepelong ea metsi ea litoropong le mahaeng le kantle, ntlafatsong ea metsi a mahaeng, nosetso ea masimong, lipeipi tsa phetisetso ea letsoai le lik'hemik'hale, phepelo ea metsi ea indasteri ea temo ea metsi, moea oa merafo, phepelo ea metsi le drainage, sefafatsi sa ho lokisa mobu. nosetso le diporojeke tse ding tse kgolo le tse nyane.
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.
