rongo

Na te mea ko te pokey o te polyethylene taumaha (UHMW-PE) i roto i te ahua whakarewa he rite ki te 108Pa*s, he tino rawakore te rere, a he tata kore te taupae rewa, he uaua ki te tukatuka ma nga tikanga miihini whanui. .Kua tere whakawhanakehia te hangarau tukatuka polyethylene (UHMW-PE) ultrahigh molecular weight polyethylene (UHMW-PE), na roto i te whakarereketanga o nga taputapu tukatuka noa, kua hanga i te polyethylene taumaha molecular ultrahigh (UHMW-PE) mai i te pehi tuatahi - te whakahiatotanga whakahiato whanaketanga ki te tangohanga, te pupuhi pupuhi me te werohanga. niao me etahi atu tikanga motuhake o te niao.
Tikanga whānui
1. Te pehi me te waituhi
(1) Ko te pehi me te whakahiato ko te tikanga tukatuka taketake o te polyethylene molecular taumaha ultra-tiketike (UHMW-PE).He iti rawa te kaha o te whakaputanga o tenei tikanga, a he ngawari ki te puta te waikura me te paheketanga.Hei whakapai ake i te mahi whakaputa, ka taea te whakamahi whakamahana hiko tika
(2) Ultra-tiketike tere fusion tukatuka tikanga, te whakamahi i te momo momo matatahi, te tere mōrahi o te hurihanga mata taea tae 150m / s, kia taea te rauemi whakatika ki te pāmahana tukatuka i roto i te torutoru noa hēkona.
2. Tangohanga niao
Ko te nuinga o nga taputapu whakakikorua ko te kaihoroi piu, ko te kaihoroi wiri kotahi me te kaikiri wiri mahanga.Kei te whakamahia te nuinga o nga kaihoroi mahanga i roto i te huarahi kotahi e huri ana i te kaihoroi mahanga.
I te tekau tau atu i 1960, i whakamahia te nuinga o te plunger extruder.I waenganui o te tekau tau atu i 1970, ko Hapani, ko te United States me te Hauauru o Tiamana i whakawhanake i te tukanga tangohanga hiko kotahi.Ko te kamupene Mitsui Petrochemical o Japan i eke tuatahi ki te angitu o te hangarau tangohanga rakau porowhita i te tau 1974. I te mutunga o te tau 1994, i whakawhanakehia te φ45 momo ultra-high molecular weight polyethylene (UHMW-PE) motuhake mokowhiti extruder kotahi, me te angitu o te momo φ65 momo kotahi. i tutuki i te tau 1997 nga raina whakaputa pupa extruder pipe ahumahi.
(3) Hangaia te werohanga
I whakawhanakehia e Mitsui Petrochemicals te tukanga whakarewa werohanga i te tau 1974 me te hokohoko i te tau 1976, whai muri mai ko te whakanekehanga i te werohanga hurihanga.I te tau 1985, i mohio ano a Hoechst ki te mahi whakakikorua o UHMW-PE.I te tau 1983, i whakarereketia te miihini werohanga whare XS-ZY-125A.I werohia paitia te wira tautoko i te polyethylene (UHMW-PE) tino teitei molecular weight polyethylene (UHMW-PE) me te ringaringa toki mo te papu wai mo te raina whakangao karepe pia.I te tau 1985, i werohia ano te hononga horihori mo te rongoa.
(4) pupuhi pupuhi
Ultra-high molecular weight polyethylene (UHMW-PE) tukatuka, ka mate te tangohanga rauemi mai i te waha, na te whakaora elastic me te whakaheke, me te tata kaore he ahuatanga sagging, na nga ipu tuwhera, ina koa nga ipu nui, penei i te tank hinu, pupuhi pupuhi niao ki te hanga tikanga pai.Ultrahigh molecular weight polyethylene (UHMW-PE) pupuhi pupuhi ka taea hoki te arahi ki te kiriata mahi teitei me te kaha o te kaha i roto i te ahunga poutū me te whakapae, e whakaoti ana i te raruraru kaore i te rite te kaha o te kiriata HDPE i te ahunga poutū me te whakapae mo te he wa roa, he ngawari hoki ki te paheketanga roa.
