Ko te polyethylene molecular weight ultrahigh (UHMW-PE) he momo kirihou hangarau thermoplastic me te hanganga raina me nga taonga matawhānui pai.
I mua i te tekau tau atu i 1980, e 8.5% te pikinga toharite o te tau o te ao.I muri i nga tau 1980, ka eke te tere o te tipu ki te 15% ~ 20%.Ko te toharite tipu o ia tau i Haina kei runga ake i te 30%.I te tau 1978, ko te kai o te ao ko te 12,000 ~ 12,500 tone, a, i te tau 1990, ko te hiahia o te ao mo te 50,000 tone, ko te United States e 70%.Mai i te tau 2007 ki te 2009, ka huri haere a Haina hei wheketere kirihou miihini o te ao, a, i tino tere te tipu o te umanga polyethylene taumaha ultra-rota.Ko te hitori o te whanaketanga e whai ake nei:
Ko te ariā taketake o te ultrahigh molecular weight polyethylene fiber i whakaarohia tuatahitia i nga tau 1930.
Ko te putanga o te miro miro me te miro kirihou kua tino pakaru i roto i te hangarau o te polyethylene taumaha-nui-nui.
I te tekau tau atu i 1970, ko Capaccio raua ko Ward o te Whare Wananga o Leeds i te United Kingdom te tuatahi i whakawhanake i te muka polyethylene taumaha teitei me te taumaha ngota o te 100,000.
I te tau 1964, i pai te whakawhanake me te whakauru ki nga mahi ahumahi i Haina.
I roto i te 1975, i hangaia e te Netherlands a Gelspinning ma te whakamahi i te decalin hei whakarewa, i pai te whakarite i te muka UHMWPE, me te tono mo te patent i te 1979. I muri i nga tau tekau o te rangahau, ka whakamatauhia ko te tikanga hurihuri gel he tikanga whai hua mo te whakaputa i te muka polyethylene kaha teitei, e whai hua ana te ahumahi a meake nei.
I te tau 1983, i hangaia te muka polyethylene (UHMWPE) ultra-high molecular weight polyethylene (UHMWPE) i Hapani ma te tango i te kiri me te tikanga totoro nui me te paraffin hei whakarewa.
I Haina, i whakaingoatia te putorino polyethylene molecular ultra teitei hei kaupapa whakatairanga matua mo nga whakatutukitanga putaiao me te hangarau o te motu i te tau 2001 e te tuhinga a te Manatu o te Putaiao me te Hangarau (2000)056, no nga rawa matū hou me nga hua hou.Kua whakarārangitia e te Manatū Pūtaiao me te Hangarau o te Kāhui Whakamaherehere Kāwanatanga he putorino polyethylene taumaha mole tino teitei hei kaupapa matua i roto i te mara matua o te ahumahi hangarau tiketike.
Tautuhia nga tikanga
Ko te polyethylene molecular taumaha ultra-tiketike he momo polymer, he uaua ki te tukatuka, me te kaha ki te whakakakahu i te kakahu, te whakahinuhinu whaiaro, te kaha nui, te mau o nga matū, te kaha o te mahi anti-tahekeheke, na reira i roto i te whakahawea o te pono me te teka. polymer polyethylene, me aro tatou ki nga ahuatanga o taua mea, ko te tikanga whakawehe motuhake e whai ake nei:
1. Ture pauna: ko te rahinga o nga hua i hangaia mai i te polyethylene taumaha teitei ultra-tiketike i waenga i te 0.93 me te 0.95, he iti te kiato, a ka rewa i runga i te mata wai.Mena ehara i te polyethylene parakore, ka totohu ki raro.
2. Tikanga Ataata: he papatahi te mata o te polyethylene taumaha tino ultra-tiketike, he rite, he maeneene me te kiato o te waahanga he tino rite, ki te kore he parakore te tae o te rauemi polyethylene he atarua, kaore i te rite te kiato.
3 tikanga whakamātautau mata: parakore ultra-tiketike rāpoi taimaha polyethylene flanging pito mata he porotaka, kākahu, maheni, ki te kore parakore rauemi polyethylene flanging pito kapiti mata, a i muri i whakawera flanging ka puta te āhuatanga para.
