Ultrahigh molecular weight polyethylene (UHMW-PE) ke mofuta oa polasetiki ea boenjiniere ea thermoplastic e nang le sebopeho sa mela le thepa e phethahetseng e felletseng.
Pele ho lilemo tsa bo-1980, karolelano ea selemo le selemo ea khōlo ea lefatše e ne e le 8,5%.Kamora lilemo tsa bo-1980, sekhahla sa kholo se fihlile ho 15% ~ 20%.Karolelano ea sekhahla sa kholo ea selemo le selemo Chaena e ka holimo ho 30%.Ka 1978, tšebeliso ea lefats'e e ne e le lithane tse 12,000 ~ 12,500, 'me ka 1990, tlhoko ea lefats'e e ne e ka ba lithane tse 50,000, tseo United States e neng e le karolo ea 70 lekholong.Ho tloha 2007 ho isa 2009, China butle-butle e ile ea fetoha feme ea lefats'e ea boenjiniere ba polasetiki, 'me indasteri ea polyethylene ea boima ba limolek'hule e ile ea hōla ka potlako haholo.Nalane ea nts'etsopele e tjena:
Khopolo ea mantlha ea ultrahigh molecular weight polyethylene fiber e ile ea hlahisoa ka lekhetlo la pele ka bo-1930.
Ho hlaha ha gel le ho ohia ka polasetiki ho entse tsoelo-pele e kholo ho thekenoloji ea polyethylene ea boima bo phahameng ba molek'hule.
Lilemong tsa bo-1970, Capaccio le Ward ea Univesithi ea Leeds United Kingdom ba ile ba qala ho hlahisa fiber e phahameng ea molek'hule ea polyethylene e boima ba molek'hule ea 100,000.
Ka 1964, e ile ea ntlafatsoa ka katleho 'me ea kenngoa tlhahisong ea indasteri Chaena.
Ka 1975, Netherlands e ile ea qapa Gelspinning e sebelisang decalin e le solvent, e lokiselitsoeng ka katleho UHMWPE fiber, 'me ea kenya kopo bakeng sa patent ka 1979. Ka mor'a lilemo tse leshome tsa lipatlisiso, ho pakoa hore mokhoa oa ho ohla gel ke mokhoa o atlehang oa ho hlahisa fiber e matla ea polyethylene, e nang le bokamoso bo tšepisang ba indasteri.
Ka 1983, ultra-high molecular weight polyethylene (UHMWPE) fiber e ile ea hlahisoa Japane ka gel extrusion le mokhoa o motle oa ho otlolla ka parafine e le solvent.

Khetholla mekhoa
Polyethylene ea boima bo phahameng ba molek'hule ke mofuta oa motsoako oa polymer, ho thata ho sebetsa, 'me o na le khanyetso ea superwear, ho itlotsa, matla a phahameng, thepa ea lik'hemik'hale e tsitsitseng, ts'ebetso e matla ea ho thibela botsofali, kahoo ho khethollo ea 'nete le ea bohata. polymer polyethylene, re tlameha ho ela hloko litšobotsi tsa eona, mokhoa o ikhethileng oa khethollo ke o latelang:
1. Molao oa ho lekanya: karolo ea lihlahisoa tse entsoeng ka polyethylene e hloekileng ea ultra-high molecular boima e pakeng tsa 0.93 le 0.95, boima bo nyenyane, 'me bo ka phaphamala holim'a metsi.Haeba e se polyethylene e hloekileng, e tla teba ho ea tlaase.
2. Mokhoa o bonahalang: holim'a polyethylene ea 'nete ea ultra-high molek'hule e bataletse, e ts'oanang, e boreleli, 'me boima ba karolo bo tšoana haholo, haeba bo sa hloeka polyethylene 'mala oa lintho tse bonahalang o fokola' me boima ha bo tšoane.
3 mokhoa oa teko ea bohale: polyethylene flanging qetellong ea boima ba limolek'hule sefahleho se pota-potile, se ts'oanang, se boreleli, haeba e se lintho tse hloekileng tsa polyethylene tse senyang sefahleho, 'me ka mor'a ho futhumatsa ho tla hlaha ntho e makatsang.
