Ultrahigh ya molekuline yuburemere polyethylene (UHMW-PE) nubwoko bwa plastiki yubuhanga bwa termoplastique ifite imiterere yumurongo hamwe nibintu byiza byuzuye.
Mbere ya za 1980, ikigereranyo cy'ubwiyongere bw'umwaka ku isi cyari 8.5%.Nyuma ya za 1980, umuvuduko witerambere wageze kuri 15% ~ 20%.Ikigereranyo cy'ubwiyongere bw'umwaka mu Bushinwa kiri hejuru ya 30%.Mu 1978, isi yakoresheje toni 12,000 ~ 12.500, naho mu 1990, isi ikenera hafi toni 50.000, muri zo Amerika ikaba yari 70%.Kuva mu 2007 kugeza 2009, Ubushinwa bwabaye buhoro buhoro uruganda rukora inganda za plastiki ku isi, kandi inganda za polyethylene zifite uburemere bukabije cyane.Amateka yiterambere ni aya akurikira:
Igitekerezo cyibanze cya ultrahigh molekulari ya polyethylene fibre cyatanzwe bwa mbere muri 1930.
Kugaragara kwa gel kuzunguruka hamwe no kuzunguruka bya pulasitike byateye intambwe nini mu ikoranabuhanga rya ultra-high molecular polyethylene.
Mu myaka ya za 70, Capaccio na Ward bo muri kaminuza ya Leeds mu Bwongereza babanje gukora fibre ifite uburemere buke bwa polyethylene ifite uburemere bwa 100.000.
Mu 1964, yateye imbere neza ishyirwa mubikorwa byinganda mubushinwa.
Mu 1975, Ubuholandi bwavumbuye Gelspinning ikoresheje decalin nk'umuti, itegura neza fibre UHMWPE, kandi isaba ipatanti mu 1979. Nyuma y’imyaka icumi y’ubushakashatsi, byagaragaye ko uburyo bwo kuzunguruka gel ari uburyo bwiza bwo gukora fibre polyethylene ikomeye, ikaba ifite ejo hazaza h'inganda.
Mu 1983, fibre yuburemere bwa polyethylene (UHMWPE) yakozwe cyane mubuyapani hakoreshejwe gel hamwe nuburyo bwo kurambura hamwe na paraffine nka solvent.
Mu Bushinwa, umuyoboro mwinshi wa polyethylene ufite uburemere buke washyizwe ku rutonde rwa gahunda nyamukuru yo guteza imbere ubumenyi n’ikoranabuhanga mu rwego rw’igihugu mu 2001 na Minisiteri y’ubumenyi n’ikoranabuhanga (2000) 056, ikaba ari ibikoresho bishya bya shimi n’ibicuruzwa bishya.Minisiteri y’ubumenyi n’ikoranabuhanga ya komisiyo ishinzwe igenamigambi rya Leta yashyize ku rutonde umuyoboro wa polyethylene ufite uburemere buke cyane bwa molekile nk’umushinga w’ibanze mu rwego rw’inganda z’ikoranabuhanga rikomeye.
Menya uburyo
Uburemere bukabije bwa molekuline polyethylene ni ubwoko bwa polymer, biragoye kuyitunganya, kandi ifite imbaraga zo kwihanganira kwambara, kwisiga, imbaraga nyinshi, imiti ihamye, imikorere irwanya gusaza, bityo mukuvangura ukuri nibinyoma polymer polyethylene, tugomba kwitondera ibiranga, uburyo bwihariye bwo kuvangura nuburyo bukurikira:
1. Itegeko ryo gupima: igipimo cyibicuruzwa bikozwe muri ultra-high-molekulari yuburemere bwa polyethylene iri hagati ya 0,93 na 0,95, ubucucike ni buto, kandi burashobora kureremba hejuru y’amazi.Niba atari polyethylene yuzuye, izarohama.
2. Uburyo bugaragara: ubuso bwa ultra-high-molekulari yuburemere bwa polyethylene burasa, buringaniye, buringaniye kandi ubucucike bwigice burasa cyane, niba atari ibara rya polyethylene yuzuye ibara ryijimye kandi ubucucike ntabwo ari bumwe.
Uburyo 3 bwo gupima: ultra-high-molekulari yuburemere bwa polyethylene flanging isura yanyuma irazengurutse, iringaniye, iroroshye, niba atari ibikoresho bya polyethylene byuzuye flanging end face crack, kandi nyuma yo gushyushya flanging bizagaragara nkibintu bya slag.
