Ultrahigh molecular uremu polyethylene (UHMW-PE) imhando ye thermoplastic engineering purasitiki ine mutsara chimiro uye yakanakisa yakazara zvivakwa.
Ma1980 asati asvika, avhareji yekukura kwepasirese pagore yaive 8,5%.Mushure memakore ekuma1980, chiyero chekukura chakasvika 15% ~ 20%.Avhareji yegore rekukura mwero muChina iri pamusoro pe30%.Muna 1978, kushandiswa kwenyika kwaiva 12,000 ~ 12,500 matani, uye muna 1990, chido chepasi chakanga chiri pamusoro pe50,000 matani, iyo United States yakaverengera 70%.Kubva muna 2007 kusvika 2009, China zvishoma nezvishoma yakava fekitori yepasi rose yeinjiniya yemapurasitiki, uye iyo indasitiri yehuremu hwe polyethylene yakakura nekukurumidza.Nhoroondo yebudiriro yakaita seizvi:
Dzidziso yekutanga yeultrahigh molecular weight polyethylene fiber yakatanga kutaurwa muma1930s.
Kubuda kwegel kutenderera uye kutenderera kwepurasitiki kwaita budiriro huru muhunyanzvi hwe Ultra-yakakwirira molecular uremu polyethylene.
Mumakore ekuma1970, Capaccio neWard yeYunivhesiti yeLeeds kuUnited Kingdom yakatanga kugadzira high molecular weight polyethylene fiber ine huremu hwe100,000.
Muna 1964, yakabudirira kugadzirwa uye kuiswa mukugadzirwa kwemaindasitiri muChina.
Muna 1975, Netherlands yakagadzira Gelspinning ichishandisa decalin se solvent, yakabudirira kugadzirira UHMWPE fiber, uye yakanyorera patent muna 1979. Mushure memakore gumi ekutsvakurudza, zvinoratidzwa kuti gel kuruka nzira inzira inobatsira yekubudisa simba guru re polyethylene fiber, iyo ine ramangwana reindasitiri rinovimbisa.
Muna 1983, ultra-high molecular weight polyethylene (UHMWPE) faibha yakagadzirwa muJapan negel extrusion uye super stretching method ine parafini se solvent.
MuChina, yakakwira molecular uremu polyethylene pombi yakanyorwa seyakakosha kukurudzira chirongwa chenyika yesainzi uye tekinoroji kubudirira muna 2001 nebazi reSainzi neTekinoroji (2000)056 gwaro, rinova remakemikari matsva uye zvigadzirwa zvitsva.Bazi reSainzi neTekinoroji reState Planning Commission rakanyora Ultra-yakakwirira molecular uremu polyethylene pombi sepurojekiti yakakosha mundima yakakosha yeindasitiri yepamusoro-soro.
Ziva nzira
Ultra-yakakwirira molecular weight polyethylene imhando yepolymer compound, inonetsa kugadzirisa, uye ine super kupfeka resistance, self-lubricating, high simba, stable chemical properties, yakasimba anti-aging performance, saka mukusarura kwechokwadi nenhema. polymer polyethylene, isu tinofanirwa kutarisisa kune hunhu hwayo, iyo chaiyo yekusarura nzira ndeyekutevera:
1. Kuyera mutemo: chikamu chezvigadzirwa zvakagadzirwa ne pure ultra-high molecular weight polyethylene iri pakati pe 0.93 ne 0.95, iyo density idiki, uye inogona kuyangarara pamusoro pemvura.Kana isiri polyethylene yakachena, inonyura pasi.
2. Nzira yekuona: pamusoro peiyo chaiyo-yakakwirira molecular uremu polyethylene yakapfava, yunifomu, yakatsetseka uye density yechikamu yakanyatso yunifomu, kana isina kuchena polyethylene zvinhu ruvara yakasviba uye density haina yunifomu.
3 kumucheto bvunzo nzira: yakachena Ultra-yakakwirira molecular uremu polyethylene flanging kupera chiso chakatenderera, yunifomu, yakatsetseka, kana isiri yakachena polyethylene zvinhu zvinoputika kupera kwechiso kutsemuka, uye mushure mekupisa kupenya kuchaonekwa slag chiitiko.
