iindaba

I-Ultrahigh molecular weight polyethylene (UHMW-PE) luhlobo lweplastiki yobunjineli be-thermoplastic enesakhiwo somgca kunye neempawu ezigqwesileyo ezibanzi.
Phambi kweminyaka yee-1980, umndilili wokukhula ngonyaka wehlabathi wawusisi-8.5%.Emva kweminyaka yoo-1980, izinga lokukhula lafikelela kwi-15% ~ 20%.Umyinge wokukhula ngonyaka e-China ungaphezulu kwama-30%.Ngo-1978, ukusetyenziswa kwehlabathi kwakuyi-12,000 ~ 12,500 yeetoni, kwaye ngo-1990, imfuno yehlabathi yayimalunga neetoni ezingama-50,000, apho i-United States yayibalelwa kwi-70%.Ukususela ngo-2007 ukuya ku-2009, i-China ngokuthe ngcembe yaba yimveliso yeplastiki yobunjineli behlabathi, kwaye imboni ye-polyethylene ye-ultra-molecular yaphuhliswa ngokukhawuleza.Imbali yophuhliso imi ngolu hlobo lulandelayo:
Ithiyori esisiseko ye-ultrahigh molecular weight polyethylene fiber yacetywa kuqala kwi-1930s.
Ukuvela kwejel ejikelezayo kunye neplastiki ejikelezayo yenze impumelelo enkulu kwitekhnoloji ye-ultra-high molecular weight polyethylene.
Ngama-1970, iCapaccio kunye neWadi yeYunivesithi yaseLeeds e-United Kingdom yaqala ukuphuhlisa i-molecular weight polyethylene fiber kunye ne-molecular weight ye-100,000.
Ngo-1964, yaphuhliswa ngempumelelo kwaye yafakwa kwimveliso yemizi-mveliso e-China.
Ngo-1975, i-Netherlands yasungula i-Gelspinning isebenzisa i-decalin njenge-solvent, yalungiselela ngempumelelo i-UHMWPE ifayibha, kwaye yafaka isicelo se-patent ngo-1979. Emva kweminyaka elishumi yophando, kubonakaliswe ukuba indlela yokujikeleza ijeli yindlela esebenzayo yokuvelisa i-polyethylene fiber enamandla kakhulu, enekamva loshishino elithembisayo.
Ngo-1983, i-ultra-high molecular weight polyethylene (UHMWPE) ifayibha yaveliswa eJapan ngejel extrusion kunye nendlela yokwelula kakhulu ngeparafini njengesinyibilikisi.
E-China, umbhobho we-polyethylene wobunzima bemolekyuli ephezulu wadweliswa njengesicwangciso esingundoqo sokukhuthaza impumelelo yesizwe yenzululwazi nethekhnoloji ngo-2001 nguMphathiswa wezeNzululwazi kunye neTekhnoloji (2000)056 uxwebhu, eyemathiriyeli emitsha yeekhemikhali kunye neemveliso ezintsha.UMphathiswa wezeNzululwazi kunye neThekhnoloji yeKomishoni yoCwangciso lukaRhulumente idwelise i-ultra-high molecular weight polyethylene pipe njengeprojekthi ephambili kwintsimi ephambili ye-high-tech industry.
Chonga iindlela
I-Ultra-high molecular weight polyethylene luhlobo lwepolymer compound, kunzima ukuyiqhuba, kwaye inokumelana nokunxiba okuphezulu, ukuzithambisa, amandla aphezulu, iipropathi zekhemikhali ezizinzileyo, ukusebenza okuqinileyo kokuchasana nokuguga, ngoko ke kucalucalulo lwenyani kunye nobuxoki. i-polymer polyethylene, kufuneka sinikele ingqalelo kwiimpawu zayo, indlela yocalucalulo ethile ngolu hlobo lulandelayo:
1. Umgaqo wokulinganisa: umlinganiselo weemveliso ezenziwe nge-polyethylene ecocekileyo ye-ultra-high molecular weight iphakathi kwe-0.93 kunye ne-0.95, ubuninzi buncinci, kwaye buyakwazi ukudada phezu kwamanzi.Ukuba ayiyo polyethylene ecocekileyo, iya kutshona ukuya ezantsi.
2. Indlela Visual: umphezulu yokwenene ultra-high molekyuli ubunzima polyethylene sicaba, iyunifomu, agudileyo kunye noxinaniso lwecandelo iyunifomu kakhulu, ukuba akukho polyethylene ecocekileyo impahla umbala imfiliba kunye noxinaniso ayifani.
3 edge test indlela: esulungekileyo ultra-high molecular ubunzima polyethylene flanging ekupheleni ubuso bungqukuva, iyunifomu, agudileyo, ukuba ayiyonto esulungekileyo polyethylene imathiriyeli flanging ekupheleni ubuso ukuqhekeka, kwaye emva kokufudumeza flanging iya kuvela slag isenzeko.
