Ho sebetsa le ho Etsa Lipolasetiki,Ts'ebetso ea ho Extrusion ea Plastiki

Plastic extrusion ke mokhoa oo ho oona polasetiki e qhibilihang ebe e etsoa ka mokhoa o tsoelang pele.Ts'ebetso ena e sebelisetsoa ho hlahisa lintho tse kang phala, terata, li-tubing, terata, liforeimi tsa lifensetere le railing…

Ho sebetsa le ho Etsa Lipolasetiki

Plastiki ke li-polymers tse nang le boima bo phahameng ba limolek'hule.Lipolasetiki li tloaelehile lihlahisoa tse ngata, ho tloha ka hare ho likoloi ho ea ho liphaephe.Ho sebetsa le ho hlahisa lipolasetiki ho kenyelletsa mehato e meraro ea motheo: 1) ho fana ka litšobotsi tse itseng ho li-resin tsa polasetiki tse nang le lisebelisoa tsa lik'hemik'hale, ho akarelletsa le lisebelisoa, li-flame retardant agents, colorants le plasticizers;2) ho fetola lisebelisoa tse tala (li-granules tsa polasetiki, li-pellets, lishiti, maro kapa li-plastiki tse entsoeng esale pele) hore e be libopeho tse bohareng kapa tsa ho qetela;le 3) ho qeta sehlahisoa ka mekhoa ea ho bopa / ho etsa, joalo ka ho bopa ente kapa extrusion.Ho etsa ente ho kenyelletsa ho futhumatsa li-granules kapa li-pellets sebakeng sa mokelikeli le khatello ea ho kenya polasetiki ea mokelikeli ka har'a hlobo e batang bakeng sa ho e beha.Extrusion e kenyelletsa ho sututsa thepa ea polasetiki ea mokelikeli ka lesela ho etsa mefuta e telele, e tsoelang pele, joalo ka liphaephe kapa li-tubes.

The Basic Process of Plastic Extrusion

Mokhoa ona o sebelisa resin ea polasetiki, e leng lifaha tse nyenyane tsa polasetiki, tse tšeloang ka sekoti ka har'a moqomo o futhumetseng oa extruder.Ho na le sekoti se potolohang, seo hangata se fetohang ho 120 rpm, se sututsa resin ka har'a moqomo kaha hangata e qhibiliha kae kapa kae ho tloha ho likhato tse 392 ho isa ho likhato tse 527 tsa Fahrenheit, ho latela polima eo resin e entsoeng ka eona.Ho thusa ho fokotsa kotsi ea ho chesa resin e feteletseng, mocheso o eketseha butle-butle ho tloha lehlakoreng le leng la moqomo ho ea ho le leng.

Ka pele ho barrel, ho na le skrine seo resin e qhibilihisitsoeng e phunyeletsoang ho sona ho thusa ho sefa ntho leha e le efe e ka 'nang ea silafatsa resin.Hang ha resin ea thermoplastic e qhibilihisitsoeng e feta skrineng, pompo ea phepelo e romela resin ka lesela le nang le sebopeho, ebe le fa sehlahisoa boemo ba sona.

Sebopeho sena kapa boemo bona, bo ka etsoa ka ho tsoelang pele, ka bolelele leha e le bofe.

Qetellong, sehlahisoa se tlameha ho pholile.Hangata sena se etsoa ka ho hlapa ka metsi.Plastiki e boloka mocheso hantle, kahoo ho pholile ho nka nako.Ka lebaka la sena, hangata metsi a hlapa a koaletsoe 'me ho sebelisoa vacuum ho thibela sehlahisoa ho lahleheloa ke sebōpeho sa sona ha se ntse se pholile.
