Uma sikhuluma "ngezinto eziqine kakhulu eMhlabeni," abantu abaningi basacabanga ngamadayimane noma insimbi eqinisiwe. Kodwa emkhakheni wesayensi yezinto zanamuhla, kukhona i-polymer eye yachaza kabusha imingcele yefiziksi ngokuthula. I-Ultra-High Molecular Weight Polyethylene (UHMWPE) akuyona nje ipulasitiki; iyinto yobuciko yama-molecule. Inamandla ngokuphindwe kayi-15 kunensimbi, kodwa ilula ngokwanele ukuntanta emanzini.
Kwa-Huidun UHMWPE, umgomo wethu ukusebenzisa leli khono lama-molecule ezindleleni zokusetshenziswa kwezimboni, olwandle, kanye nokuvikela. Ukuze siqonde ngempela ukuthi kungani imicu yethu isebenza ngendlela esebenza ngayo, sidinga ukubheka ngale kobuso bese singena ekwakhiweni okungabonakali kwe-polymer uqobo.
Isici "sesisindo sama-molecule"
Imfihlo ye-UHMWPE isegameni layo: "Isisindo Sama-Molecular Esiphezulu Kakhulu." Ngenkathi i-polyethylene ejwayelekile (uhlobo olusetshenziswa ezikhwameni zepulasitiki noma emabhodleleni) inesisindo sama-molecule esiphakathi kuka-20,000 no-300,000 g/mol, i-UHMWPE inesisindo sama-molecule esiphakathi kuka-3.5 no-7.5 million g/mol.
Cabanga ngesitsha sezingcezu ezimfushane zentambo uma kuqhathaniswa nesitsha sezingcezu ezinde ngamamayela. Uma uzama ukuzihlukanisa, izintambo ezimfushane ziyashelelana kalula. Kodwa-ke, izintambo ezinde kakhulu ku-UHMWPE ziyathandeka futhi zihlangane kangangokuthi zidala inani elikhulu lendawo ephakathi kwama-molecule. Lobu bude obukhulu bezintambo yisona sizathu esiyinhloko sokuthi izinto zikwazi ukumelana nokucindezeleka okukhulu ngaphandle kokuphuka.
Ukuphotha Ngejeli: Ukuguqula Uketshezi Lube Amandla
Ukuba nezintambo ezinde zama-molecule kuyingxenye yempi kuphela. Ukuze iguqule le polymer eluhlaza ibe yi-fiber esebenza kahle kakhulu, kumele idlule enkambisweni ekhethekile ebizwa ngokuthi i-Gel Spinning. Ezikhungweni zethu zokukhiqiza zaseHuidun, lesi yisigaba esibalulekile lapho isayensi ihlangana khona nokukhiqiza.
Indlela I-Gel Spinning Esebenza Ngayo: I-polymer ye-UHMWPE incibilikiswa ku-solvent ukuze yakhe isimo esifana ne-gel. Kulesi simo, amaketanga e-polymer ahlukaniswa kancane. Njengoba i-gel ikhishwa nge-spinneret, amaketanga ayadonswa futhi aqondiswe ohlangothini olulodwa. Phakathi nezigaba ezilandelayo zokupholisa nokwelula, la maketanga azivumelanisa kahle ne-fiber axis.
Lesi sakhiwo "esigxile kakhulu" yisona esihlukanisa i-UHMWPE kwamanye amapulasitiki. Ngenxa yokuthi cishe wonke amaketanga ama-molecule aqondaniswe ohlangothini lwe-fiber, umthwalo usatshalaliswa ngokulinganayo kuwo wonke umgogodla wama-molecule we-polymer. Uma udonsa i-fiber ye-Huidun UHMWPE, udonsa ngempumelelo ngokumelene nezibopho ze-carbon-carbon ngokwazo.
I-Crystallinity kanye ne-Van der Waals Forces
Ngaphandle kokuqondanisa okulula, i-UHMWPE i-crystalline kakhulu. Kumapulasitiki amaningi, ama-molecule angcolile futhi "a-amorphous." Kuma-fiber e-UHMWPE, ngaphezu kuka-80% wesakhiwo uhlelwe nge-lattice ehlanganisiwe kahle ye-crystalline. Lokhu kuxinana kuvumela amandla aphezulu e-Van der Waals - ukukhanga okungabonakali kwe-electromagnetic phakathi kwama-molecule - ukuthi kubambe. Ngenkathi isibopho esisodwa se-Van der Waals sibuthakathaka, izigidi zazo ezisebenza kuchungechunge lwama-molecule oluyi-unit eziyizigidi ezingu-7 zakha isibopho okunzima kakhulu ukusigqabula.
Ukumuncwa Kwamandla: Umkhawulo We-Ballistic
Esinye sezimpawu eziphawuleka kakhulu ze-UHMWPE yikhono layo lokumunca nokusabalalisa amandla. Ngenxa yokuthi ijubane lomsindo ngale polymer eqondiswe kakhulu liphezulu kakhulu, amandla avela ekushayweni (njengenhlamvu noma inkemba ebukhali) adluliselwa kunethiwekhi yefayibha ngokushesha kunokuba izinto zingangena.
Yingakho i-UHMWPE iyinto ekhethwayo yezivikelo zomzimba zesimanje kanye namagilavu anganqunyiwe. Ayigcini nje ngokuyivimba into; iyibamba ngokusabalalisa amandla endaweni ebanzi, inciphise "ukuguquguquka kobuso bangemuva" futhi ikhulise izinga lokusinda komuntu oyigqokile. KwaHuidun, sithuthukisa ukuqina kwefayibha yethu ukuqinisekisa ukuthi lokhu kusakazeka kwamandla kuyafana kuwo wonke amaqoqo.
Ukungavikeleki Kwemvelo
Isakhiwo samakhemikhali se-UHMWPE asisebenzi ngokuphelele. Njengoba sakhiwe yi-carbon ne-hydrogen ngokuphelele ochungechungeni olugcwele, azikho "izindawo ezibuthakathaka" zamakhemikhali noma umswakama ezingahlasela. Asithandi amanzi, okusho ukuthi asimunci amanzi nhlobo, futhi asikwazi ukuwohloka kwezinto eziphilayo ezihlupha imicu yemvelo. Kungakhathaliseki ukuthi ivezwa imisebe ye-UV enamandla ehlane noma i-salt spray phakathi nolwandle, ubuqotho bama-molecule e-Huidun fiber abushintshi.
