Hobane viscosity ea ultra-high molecular weight polyethylene (UHMW-PE) e boemong ba ho qhibiliha e holimo ho 108Pa*s, metsi a fokola haholo, 'me melt index ea eona e batla e le zero, ho thata ho sebetsanoa ka mekhoa e tloaelehileng ea machining. .Theknoloji ea ho sebetsa ea polyethylene (UHMW-PE) ea Ultrahigh molek'hule (UHMW-PE) e 'nile ea ntlafatsoa ka potlako, ka phetoho ea lisebelisoa tse tloaelehileng tsa ho sebetsa, e entse polyethylene ea ultrahigh molecular weight polyethylene (UHMW-PE) ho tloha ts'ebetsong ea pele ea ho hatisa - sintering molding ho ea extrusion, blowing le ente. ho bopa le mekhoa e meng e ikgethang ya ho bopa.
Mokhoa o akaretsang
1. Ho tobetsa le ho sintering
(1) Ho hatisa le ho sintering ke mokhoa oa pele oa ho sebetsa oa polyethylene ea boima bo phahameng ba molek'hule (UHMW-PE).Ts'ebetso ea tlhahiso ea mokhoa ona e tlase haholo, 'me oxidation le ho senyeha ho bonolo ho etsahala.E le ho ntlafatsa katleho ea tlhahiso, ho futhumatsa motlakase o tobileng ho ka sebelisoa
(2) Ultra-high speed fusion mokhoa oa ho sebetsa, o sebelisa motsoako oa mofuta oa lehare, lebelo le leholo la ho potoloha ha lehare le ka fihla ho 150m / s, e le hore thepa e ka nyolohela mocheso oa ho sebetsa ka metsotsoana e seng mekae feela.
2. Extrusion bōpa
Thepa ea ho bopa ea Extrusion haholo-holo e kenyelletsa plunger extruder, single screw extruder le twin screw extruder.Twin-screw extruder e sebelisoa haholo ntlheng e le 'ngoe e potolohang mafahla-screw extruder.
Lilemong tsa bo-1960, boholo ba li-plunger extruder li ne li sebelisoa.Bohareng ba lilemo tsa bo-1970, Japane, United States le Jeremane Bophirima ka tatellano li ile tsa qapa mokhoa oa ho ntša sekoti se le seng.Mitsui Petrochemical Company of Japan e ile ea qala ho finyella katleho ea thekenoloji ea "round rod extrusion" ka 1974. Qetellong ea 1994, mofuta oa φ45 mofuta oa ultra-high molecular weight polyethylene (UHMW-PE) special single screw extruder e ile ea ntlafatsoa, ​​'me katleho ea φ65 mofuta oa single Mohala oa tlhahiso ea liindasteri tsa screw extruder pipe o fihletsoe ka 1997.
(3) Ho bopa ka ente
Mitsui Petrochemicals e ntlafalitse mokhoa oa ho bopa ente ka 1974 mme ea e rekisa ka 1976, ea lateloa ke ho bopa ente ea screw.Ka 1985, Hoechst o ile a boela a hlokomela mokhoa oa ho bopa ente ea screw ea UHMW-PE.Ka 1983, mochine oa ente oa malapeng oa XS-ZY-125A o ile oa fetoloa.Lebili la polyethylene (UHMW-PE) ea boima bo phahameng ba molek'hule (UHMW-PE) le letsoho la axle bakeng sa pompo ea metsi bakeng sa mohala oa tlhahiso ea biri li ile tsa kenngoa ka katleho.Ka 1985, lenonyeletso la maiketsetso bakeng sa tšebeliso ea bongaka le lona le ile la kenngoa ka katleho.
(4) ho bopa ha moea
Ultra-high molek'hule boima polyethylene (UHMW-PE) sebetsa, ha lintho tse bonahalang extrusion e tsoang molomong shoa, ka lebaka la ho hlaphoheloa rekere le shrinkage e itseng, 'me hoo e ka bang ha ho sagging ketsahalo, kahoo lijana sekoti, haholo-holo lijana tse khōlō, tse kang tanka ea oli, ho etsa moropa ho etsa maemo a matle.Ultrahigh molecular weight polyethylene (UHMW-PE) blow molding e ka boela ea lebisa filiming e phahameng ea ts'ebetso e nang le matla a leka-lekaneng ka tsela e otlolohileng le e holimo, e rarollang bothata ba hore matla a filimi ea HDPE ha a tsitsane ka tsela e otlolohileng le e otlolohileng bakeng sa nako e telele ebile e bonolo ho baka tšenyo ea longitudinal.
