Kenyelletso ea mokhoa oa ho etsa li-hollow blowing:
Ka lebaka la phapang ea lisebelisoa tse tala, litlhoko tsa ts'ebetso, tlhahiso le litšenyehelo, mekhoa e fapaneng ea ho bopa e na le melemo e fapaneng ea ho sebetsana le lihlahisoa tse fapaneng.
Ho bopa ha lihlahisoa tse se nang letho ho kenyelletsa mekhoa e meraro ea mantlha:
1, extrusion blow molding: haholo-holo e sebelisetsoang ts'ebetso ea billet e sa tšehetsoeng;
2, ho bōptjoa ha ente: haholo-holo e sebelisetsoang ho sebetsana le billet e tšehetsoeng ke motheo oa tšepe;
3, ho otlolla ho bopa: ho kenyelletsa extrusion e otlolohileng ho bopa, ente e otlolohileng e bopa mekhoa e 'meli, e ka sebetsana le lihlahisoa tse shebaneng le biaxial, ea fokotsa litšenyehelo tsa tlhahiso haholo le ho ntlafatsa ts'ebetso ea sehlahisoa.
Ho phaella moo, ho na le mefuta e mengata ea lera, ho bōptjoa ho phunya, ho bōptjoa ha li-dip coating, foaming blow blowing, ho bōptjoa ka mahlakoreng a mararo, joalo-joalo Leha ho le joalo, 75% ea lihlahisoa tsa ho bopa ke extrusion blowing, 24% ke ente. ho bopa le 1% ke tse ling tsa ho bopa.Har'a lihlahisoa tsohle tsa ho bopa, 75% ke ea lihlahisoa tse otlolohileng ka bobeli.Melemo ea ho bopa ha extrusion blowing ke ts'ebetso e phahameng ea tlhahiso, theko e tlase ea lisebelisoa, mefuta e mengata ea hlobo le khetho ea mochini, likotsi ke sekhahla se phahameng sa maralla, ts'ebeliso ea litšila, ts'ebeliso e mpe, taolo ea botenya ba sehlahisoa, ho arohana ha thepa e tala ho na le moeli, kamora hore ho bopeha ho tlameha. ho lokisa ts'ebetso ea mantlha.Melemo ea ho bopa ha ente ke hore ha ho na litšila nakong ea ts'ebetso, botenya ba lerako la lihlahisoa le ho hasana ha thepa li ka laoloa hantle, ho nepahala ha lihlahisoa tsa molala o mosesaane ho phahame, bokaholimo ba lihlahisoa bo boreleli, tlhahiso e nyane ea batch e ka etsoa ka moruo.Bothata ke litšenyehelo tse phahameng tsa thepa ea ho bōpa, 'me ho isa tekanyong e itseng e loketse feela lihlahisoa tse nyenyane tsa ho bopa.
Maemo a ts'ebetso ea ho bopeha ha sekoti a hloka hore moea o hatelitsoeng oa hlobo e mahareng o tlameha ho hloeka.Khatello ea moea e entsoeng ka ente ke 0.55 ~ 1MPa;Khatello ea ho bopa ha extrusion ke 0.2L ~ 0.62mpa, ha khatello ea ho bopa ha tensile hangata e hlokahala ho feta 4MPa.Ka ho tiisa polasetiki, khatello e tlaase e etsa hore khatello ea ka hare ea lihlahisoa e fokotsehe, khatello ea kelello e qhalakane e tšoana le ho feta, 'me khatello e tlaase e ka ntlafatsa ho tsitsisa, tšusumetso, ho khumama le thepa e meng ea lihlahisoa.
