I-plate ye-UHMWPE ithatha uhlobo lwe-Ziegler oluphezulu lwe-catalyst low-pressure synthesis method kwaye ilawulwa ngaphezu kwe-1.5 ukuya kwi-3 yezigidi njengoko kufuneka.Ukuthathela ingqalelo ukuthotywa thermal iimolekyuli ngexesha processing, polyethylene high-uxinaniso kunye viscosity avareji molecular ngaphezu 1.7 yezigidi inokucutshungulwa kwiimveliso ezahlukeneyo ukuba ukusebenza eliphezulu ngakumbi.

1. Ukumelana nokunxiba okuphezulu: Ipleyiti ye-UHMWPE inokumelana nokunxiba ngcono phakathi kwazo zonke iiplastiki zobunjineli zangoku kwaye ijonge ngakumbi.Xa iphezulu imolekyuli, kokukhona ingagugi kakhulu imveliso, nangaphezulu kunezixhobo ezininzi zetsimbi (ezifana nentsimbi yekhabhoni, intsimbi engatyiwa, ubhedu, njl. njl.).Ngokomzekelo, iipayipi ze-UHMW-PE zinobomi benkonzo ye-4-6 ngamaxesha eemibhobho zetsimbi phantsi kweemeko ze-corrosion enamandla kunye nokugqoka okuphezulu, kunye nokwandisa ukusebenza kakuhle kokuhanjiswa ngama-20%.Ibonisa ngokupheleleyo ukuphakama "kokugcina amandla, ukukhuselwa kwendalo, uqoqosho kunye nokusebenza kakuhle".
2. Ukumelana nokubola: Ayidlanga kwilye kwaye ingasetyenziswa kwi-concentrated hydrochloric acid kwi-80 ° C.Inomsebenzi ozinzileyo kwi-75% egxininisiweyo ye-sulfuric acid kunye ne-20% ye-nitric acid.Ikwazinzile nakumanzi olwandle nakwizicoci zolwelo.
3. I-coefficient ephantsi kakhulu ye-friction: I-coefficient of friction static yi-0.07, kwaye ineempawu ezilungileyo zokuzithambisa.Yinto efanelekileyo yokuthwala, i-bushing, ibhloko ye-sliding kunye ne-lining material.Ukusebenzisa ipleyiti ye-UHMWPE njengenxalenye ye-friction yesixhobo ayinako ukunyusa kuphela ubomi obungagugiyo, kodwa nokufumana iziphumo zokonga amandla.
4. Ukuchasana kwempembelelo: Ukuxhatshazwa kwempembelelo kuqala phakathi kweeplastiki.Ingaba amandla angaphandle anamandla okanye ukuguquguquka koxinzelelo lwangaphakathi, kunzima ukuqhekeza.Amandla ayo empembelelo ngamaxesha e-nylon angama-66, amaxesha angama-20 e-polyvinyl chloride, kunye namaxesha angama-8 e-polytetrafluoroethylene.Ngokukodwa kwiindawo eziphantsi kweqondo lokushisa, amandla ayo empembelelo afikelela kwixabiso eliphezulu, kwaye ukuguquguquka kwayo kunokubonelela ngeenkqubo zokuthutha ezikhuselekileyo, isiqinisekiso esithembekileyo.
