Ngenxa yokuba i-viscosity ye-ultra-high molecular weight polyethylene (UHMW-PE) kwindawo etyhidiweyo iphezulu njenge-108Pa*s, ulwelo lubi kakhulu, kwaye isalathisi sayo sokunyibilika siphantse sibe ngu-zero, kunzima ukusetyenzwa ngeendlela zomatshini jikelele. .I-Ultrahigh molecular weight polyethylene (UHMW-PE) iteknoloji yokucubungula iye yaphuhliswa ngokukhawuleza, ngokuguqulwa kwezixhobo eziqhelekileyo zokucwangcisa, yenze i-ultrahigh molecular weight polyethylene (UHMW-PE) ukusuka ekucinezeleni kokuqala - ukuphuhliswa kwe-sintering yokubumba ukuya kwi-extrusion, ukuvuthela ukubumba kunye nokutofa. ukubumba kunye nezinye iindlela ezikhethekileyo zokubumba.
Indlela ngokubanzi
1. Ukucofa kunye nokuntywila
(1) Ukucinezela kunye ne-sintering yeyona ndlela yokuqala yokucubungula i-ultra-high molecular weight polyethylene (UHMW-PE).Ukusebenza kwemveliso yale ndlela kuphantsi kakhulu, kwaye i-oxidation kunye nokuthotywa kulula ukwenzeka.Ukuze kuphuculwe ukusebenza kakuhle kwemveliso, ukufudumeza kombane ngokuthe ngqo kungasetyenziswa
(2) I-Ultra-high speed fusion processing method, usebenzisa i-blade type mixer, isantya esiphezulu sokujikeleza kwe-blade sinokufikelela kwi-150m / s, ukwenzela ukuba izinto eziphathekayo zinokunyuka kwiqondo lokushisa kwimizuzwana embalwa kuphela.
2. Ukubunjwa kwe-Extrusion
Isixhobo sokubumba i-Extrusion ibandakanya i-plunger extruder, i-extruder screw enye kunye ne-twin screw extruder.I-Twin-screw extruder isetyenziswa kakhulu kwicala elinye elijikelezayo i-twin-screw extruder.
Ngeminyaka yee-1960, uninzi lwe-plunger extruder yasetyenziswa.Embindini weminyaka yoo-1970, iJapan, iUnited States kunye neWest Germany ziphuhlise ngokulandelelana inkqubo yokukhupha isikrufu esinye.I-Mitsui Petrochemical Company yaseJapan yaqala ukuphumelela impumelelo ye-extrusion ye-extrusion ye-extrusion technology ngo-1974. Ekupheleni kuka-1994, uhlobo lwe-ultra-high molecular weight polyethylene (UHMW-PE) olukhethekileyo lwe-screw extruder luphuhlisiwe, kunye nempumelelo ye-φ65 uhlobo olulodwa. umbhobho we-screw extruder umgca wemveliso wezoshishino waphunyezwa ngo-1997.
(3) Isitofu sokubumba
IMitsui Petrochemicals iphuhlise inkqubo yokubumba inaliti ngo-1974 yaze yarhweba ngayo ngo-1976, ilandelwa kukubuyiselana ukubunjwa kwesitofu se-screw.Ngo-1985, u-Hoechst waqaphela inkqubo yokubumba inaliti yesikrufu se-UHMW-PE.Ngo-1983, umatshini wasekhaya we-XS-ZY-125A watshintshwa.I-ultra-high molecular weight polyethylene (UHMW-PE) ivili elixhasayo kunye nomkhono we-axle wempompo yamanzi kumgca wokuvelisa i-beer caning yatofwa ngempumelelo.Ngo-1985, ijoyinti eyenziweyo yokusetyenziswa kwezonyango nayo yatofwa ngempumelelo.
(4) ukubumba ukuvuthela
Ultra-high molekyuli ubunzima polyethylene (UHMW-PE) processing, xa extrusion impahla evela emlonyeni kufa, ngenxa recovery elastic kunye nokushwabana ethile, kwaye phantse akukho nto sagging, ngoko ke izikhongozeli ezingenanto, ingakumbi izitya ezinkulu, ezifana itanki yeoli, ukubumba ukuvuthela kwegubu ukudala iimeko ezifanelekileyo.I-Ultrahigh molekyuli yobunzima be-polyethylene (UHMW-PE) ivuthela i-molding ingakhokelela kwifilimu yokusebenza ephezulu kunye namandla alinganayo kwicala elithe nkqo nelithe tye, elisombulula ingxaki yokuba amandla efilimu ye-HDPE ayihambelani kwicala elithe nkqo nelithe tye kwi-a. ixesha elide kwaye kulula ukwenza umonakalo longitudinal.
