Iyo tuvuze ku "bintu bikomeye cyane ku Isi," abantu benshi baracyatekereza kuri diyama cyangwa icyuma gishyushye. Ariko mu rwego rwa siyansi y'ibikoresho bya none, hari polymer yahinduye bucece imipaka ya fiziki. Polyethylene ifite uburemere bwa molekile nyinshi (UHMWPE) si pulasitiki gusa; ni igikoresho cy'ubuhanga cya molekile. Irusha icyuma uburemere inshuro 15, nyamara ni yoroshye bihagije ku buryo ishobora kureremba hejuru y'amazi.
Muri Huidun UHMWPE, intego yacu ni ugukoresha ubwo bushobozi bwa molekile mu bikorwa by’inganda, ibyo mu mazi no mu kurinda. Kugira ngo dusobanukirwe neza impamvu imigozi yacu ikora nk’uko ikora, tugomba kureba inyuma y’ubuso hanyuma tukinjira mu miterere mito cyane ya polima ubwayo.
Ikintu "cy'uburemere bwa molekile"
Ibanga rya UHMWPE riri mu izina ryayo: "Uburemere bwa Molekyuli Buhanitse." Nubwo polyethylene isanzwe (ubwoko bukoreshwa mu masashe ya pulasitiki cyangwa mu macupa) ifite uburemere bwa molekyuli buri hagati ya g 20.000 na 300.000/mol, UHMWPE ifite uburemere bwa molekyuli buri hagati ya g 3.5 na miliyoni 7.5/mol.
Tekereza ku gikombe cy'uduce duto tw'imigozi ugereranije n'igikombe cy'imigozi ifite uburebure bwa kilometero. Iyo ugerageje kubitandukanya, imigozi migufi iragenda inyuranaho byoroshye. Ariko, imigozi miremire cyane muri UHMWPE irahambiranywa cyane ku buryo ikora ubuso bunini bw'ingirabuzimafatizo. Ubu burebure bukabije bw'umugozi ni yo mpamvu nyamukuru ituma ibikoresho bishobora kwihanganira guhangayika cyane bidacitse.
Guhindura amazi mu buryo bwa Gel: Guhindura amazi mu buryo bw'imbaraga
Kugira iminyururu miremire ya molekile ni kimwe cya kabiri cy'intambara. Kugira ngo iyi polima mbisi ihinduke fibre ikora neza, igomba kunyura mu buryo bwihariye bwitwa Gel Spinning. Mu nganda zacu zikora Huidun, iki ni icyiciro cy'ingenzi aho siyansi ihura n'inganda.
Uko Gel Spinning Ikora: Polima ya UHMWPE ishongeshwa mu cyuma gishongesha kugira ngo igire imiterere isa na gel. Muri iki gihe, iminyururu ya polymer iba ifunguye igice. Uko gel isohoka inyuze muri spinneret, iminyururu irakururwa ikanagana mu cyerekezo kimwe. Mu gihe cyo gukonjesha no kwaguka, iyi minyururu yihuza neza neza n'umurongo wa fibre.
Iyi miterere "ishingiye cyane" ni yo itandukanya UHMWPE n'izindi pulasitiki. Kubera ko hafi ya miyoboro yose ya molekile ifatanye mu cyerekezo cya fibre, umutwaro ukwirakwira ku buryo bungana mu gice cyose cy'umugongo wa molekile ya polymer. Iyo ukuye fibre ya Huidun UHMWPE, uba ukurura neza imigozi ya karubone na karubone ubwayo.
Crystallinity na Van der Waals Force
Uretse guhuza byoroshye, UHMWPE iragaragara cyane muri kristu. Muri pulasitiki nyinshi, molecules zirahindagurika kandi "zidafite ishusho." Muri fibres za UHMWPE, hejuru ya 80% by'imiterere ishyizwe mu mwanya ufatanye cyane wa kristu. Ubu bucucike bwemerera imbaraga nyinshi za Van der Waals -- imbaraga zidasanzwe za electromagnetic hagati ya molecules - gufata. Nubwo umugozi umwe wa Van der Waals udakomeye, miliyoni nyinshi zikora ku mugozi wa molecules wa miliyoni 7 zikora umugozi ugoye cyane gucika.
Gufata Ingufu: Inkombe y'Umupira
Imwe mu miterere itangaje ya UHMWPE ni ubushobozi bwayo bwo kwinjiza no gukwirakwiza ingufu. Kubera ko umuvuduko w'amajwi unyura muri iyi polymeri ifite imiterere ikomeye ari munini cyane, ingufu ziva mu gutera (nk'isasu cyangwa icyuma gityaye) zinyuzwa mu muyoboro wa fibre vuba kurusha uko ibikoresho bishobora kwinjira.
Niyo mpamvu UHMWPE ari yo ikoreshwa cyane mu bikoresho bigezweho byo kurinda umubiri n'uturindantoki tudacika. Ntibihagarika ikintu gusa; biragifata binyuze mu gukwirakwiza imbaraga mu gace kanini, bigagabanya "impinduka mu maso" kandi byongera umuvuduko wo kubaho k'uwambaye. Muri Huidun, twongerera ubushobozi fibre yacu kugira ngo dukore neza ko iyi mashini ikwirakwira neza muri buri gice.
Ubudahangarwa bw'ibidukikije
Imiterere ya shimi ya UHMWPE ntabwo ikora cyane. Kubera ko igizwe na karuboni na hydrogen gusa mu muyoboro wuzuye, nta "bintu bike" bishobora gutera imiti cyangwa ubushuhe. Iracanga amazi, bivuze ko ifata amazi nta n'umwe, kandi ntishobora kwangirika kw'ibinyabuzima bitera imirasire karemano. Yaba ihura n'imirasire ikomeye ya UV mu butayu cyangwa iterwa n'umunyu rwagati mu nyanja, imiterere ya molekile ya fibre ya Huidun ntihinduka.
