Xa sithetha "ngezinto ezinamandla kakhulu eMhlabeni," abantu abaninzi basacinga ngeedayimani okanye intsimbi eqinisiweyo. Kodwa kwicandelo lesayensi yezinto zanamhlanje, kukho ipolymer echaze ngokutsha imida yefiziksi ngokuzolileyo. I-Ultra-High Molecular Weight Polyethylene (UHMWPE) ayisiyoplastiki nje kuphela; yi-molecular masterpiece. Inamandla ngokuphindwe kalishumi elinesihlanu kunentsimbi, kodwa ilula ngokwaneleyo ukuba ingadada emanzini.
Apha eHuidun UHMWPE, umsebenzi wethu kukusebenzisa la mandla eemolekyuli kwimizi-mveliso, elwandle, nakwimisebenzi yokukhusela. Ukuze siqonde ngokwenene ukuba kutheni iifayibha zethu zisebenza ngendlela ezisebenza ngayo, kufuneka sijonge ngaphaya komphezulu size singene kwisakhiwo se-microscopic se-polymer ngokwayo.
I-"Molecular Weight" Factor
Imfihlo ye-UHMWPE ikwigama layo elithi: "Ubunzima beMolekyuli obuphezulu kakhulu." Nangona i-polyethylene esemgangathweni (uhlobo olusetyenziswa kwiingxowa zeplastiki okanye kwiibhotile) inobunzima bemolekyuli obuphakathi kwama-20,000 nama-300,000 g/mol, i-UHMWPE inobunzima bemolekyuli obuphakathi kwe-3.5 kunye ne-7.5 yezigidi zee-g/mol.
Khawucinge ngesitya seentambo ezimfutshane xa kuthelekiswa nesitya seentambo ezinde ngamamayela. Ukuba uzama ukuzidibanisa, iintambo ezimfutshane ziyatyibilika ngokulula. Nangona kunjalo, iintambo ezinde kakhulu kwi-UHMWPE ziyabhijelana kwaye zidibana kangangokuba zenza indawo enkulu yomphezulu we-intermolecular. Olu bude be-chain obugqithisileyo sesona sizathu sokuba izinto zikwazi ukumelana noxinzelelo olukhulu ngaphandle kokuqhekeka.
Ukujikelezisa iGel: Ukuguqula ulwelo lube ngamandla
Ukuba neetsheyini ezinde zemolekyuli sisiqingatha nje semfazwe. Ukuguqula le polymer iluhlaza ibe yifayibha esebenza kakhulu, kufuneka idlule kwinkqubo ekhethekileyo ebizwa ngokuba yiGel Spinning. Kwiziko lethu lemveliso laseHuidun, eli linqanaba elibalulekileyo apho isayensi idibana khona nemveliso.
Indlela Esebenza Ngayo Ukujikelezisa Ijeli: I-polymer ye-UHMWPE inyibilika kwisinyibilikisi ukuze yenze imeko efana nejeli. Kule meko, imixokelelwane ye-polymer iyakhululeka kancinci. Njengoko ijeli ikhutshwa nge-spinneret, imixokelelwane iyatsalwa kwaye ijoliswe kwicala elinye. Ngexesha lezigaba ezilandelayo zokuphola nezolula, ezi mixokelelwane zizilungelelanisa ngokugqibeleleyo ne-fiber axis.
Olu lwakhiwo "olujolise kakhulu" yilo oluyahlula i-UHMWPE kwezinye iiplastiki. Ngenxa yokuba phantse zonke iitsheyini zemolekyuli zilungelelaniswe kwicala lefayibha, umthwalo usasazwa ngokulinganayo kuyo yonke i-molekyuli yomqolo wepolymer. Xa utsala ifayibha yeHuidun UHMWPE, utsala ngempumelelo ngokuchasene neebhondi zekhabhoni-khabhoni ngokwazo.
Crystallinity kunye neVan der Waals Forces
Ngaphaya kokulungelelaniswa okulula, i-UHMWPE ifana kakhulu nekristale. Kwiiplastiki ezininzi, iimolekyuli zingcolile kwaye "azinawo umfuziselo." Kwiifayibha ze-UHMWPE, ngaphezulu kwe-80% yesakhiwo ibekwe kwi-lattice exineneyo yekristale. Olu xinano luvumela amandla aphezulu eVan der Waals—iindawo ezinomtsalane we-electromagnetic phakathi kweemolekyuli—ukuba zibambe. Nangona ikhonkco elinye leVan der Waals libuthathaka, izigidi zazo ezisebenza kwikhonkco le-molecular yeeyunithi ezisi-7 yezigidi zenza ikhonkco elinzima kakhulu ukuliqhawula.
Ukufunxwa kwamandla: Umda weBallistic
Enye yezona mpawu zibalaseleyo ze-UHMWPE kukukwazi kwayo ukufunxa nokusasaza amandla. Ngenxa yokuba isantya sesandi kule polymer ejolise kakhulu siphezulu kakhulu, amandla avela kwimpembelelo (njengembumbulu okanye incakuba ebukhali) adluliselwa kwinethiwekhi yefayibha ngokukhawuleza kunokuba izinto zinokungena.
Yingakho i-UHMWPE iyinto ekhethwayo kwiiglavu zanamhlanje zokuzikhusela emzimbeni kunye neeglavu ezinqanda ukunqunyulwa. Ayimisi nje into; iyibamba ngokusasaza amandla kwindawo ebanzi, inciphisa "ukuguqulwa kobuso bangasemva" kwaye yonyusa izinga lokusinda komntu oyinxibileyo. KwaHuidun, siphucula ukuhambelana kwefayibha yethu ukuqinisekisa ukuba olu sasazo lwamandla lufana kulo lonke iqela.
Ukuzikhusela Kwindalo Esingqongileyo
Ulwakhiwo lweekhemikhali lwe-UHMWPE alunampembelelo ngokupheleleyo. Ekubeni yenziwe yikhabhoni nehydrogen ngokupheleleyo kwikhonkco eligcweleyo, akukho "ndawo zibuthathaka" zeekhemikhali okanye umswakama onokuzihlasela. Ayinamanzi, oko kuthetha ukuba ayifunxi manzi, kwaye ayichaphazeleki kukonakala kwezinto eziphilayo okubangela imicu yendalo. Nokuba ivezwe kwimitha ye-UV eqatha entlango okanye itshizwa ngetyuwa embindini wolwandle, ukuthembeka kweemolekyuli zefayibha yeHuidun akutshintshi.
