Kev siv tshuab ntawm UHMWPE txhaj tshuaj molding khoom

Ultra-high molecular hnyav polyethylene (UHMW-PE) feem ntau yog hais txog linear polyethylene nrog viscosity-qhov nruab nrab molecular hnyav ntawm 1.5 lab thiab qhov hnyav-qhov nruab nrab molecular hnyav ntau dua 3 lab (qhov hnyav molecular ntawm cov polyethylene zoo tib yam tsuas yog hais txog {{ 7}} lab). Nws cov qauv molecular yog tib yam li cov polyethylene zoo tib yam, tab sis nws lub cev thiab cov khoom siv kho tshuab yog qhov zoo dua li cov polyethylene zoo tib yam, xws li tsis muaj tshuaj lom, lub teeb, pheej yig, tsis tshua muaj dej nqus, thiab kev ua haujlwm zoo ultra-low kub, tshwj xeeb tshaj yog nws. cuam ​​tshuam tsis kam, tsib yam ntxwv ntawm kev puas tsuaj, tshuaj tiv thaiv corrosion, nws tus kheej lubrication thiab cuam tshuam lub zog nqus yog qhov zoo tshaj plaws ntawm tag nrho cov yas tam sim no.
UHMW-PE yeeb nkab muaj qhov zoo tshaj plaws hnav tsis kam, corrosion kuj, nws tus kheej lubrication, adhesion tsis kam, tsis-scaling thiab lwm yam ntxwv, uas yog unmatched los ntawm lwm yam yas yeeb nkab, thiab cov yeeb nkab muaj qhov zoo tshaj plaws kev ua tau zoo / nqi piv. Nws tuaj yeem hloov cov kav hlau, cam khwb cia hlau kav, cov kav hlau tsis muaj steel, cov kav dej nylon, cov kav dej polytetrafluoroethylene, cov kav dej asbestos cement thiab lwm cov kav dej rau kev thauj mus los ntawm cov khoom, hmoov cov ntaub ntawv thiab slurry, cov khoom sib xyaw ua kua (feem ntau nruab nrab thiab loj txoj kab uas hla), thiab tuaj yeem siv dav hauv metallurgy, mining, fais fab, thee, kev tsim kho thiab lwm yam lag luam.
Txawm hais tias UHMWPE muaj cov khoom zoo heev, nws yog qhov nyuaj tshwj xeeb los ua nws cov khoom vim nws cov viscosity siab thiab tsis tshua muaj siab shear npaum li cas. Rau lub sijhawm ntev, vim tias cov khoom siv hauv tsev UHMW-PE molding tshuab thiab cov cuab yeej siv tau rov qab, thiab qhov sib txawv nrog cov teb chaws siab heev, txog tam sim no, UHMW-PE cov khoom tsis tau muab tso rau hauv kev lag luam loj, thiab tsuas yog txwv. mus rau me me batch ntau lawm raws li compression-sintering los yog plunger extrusion molding txoj kev. Cov khoom lag luam feem ntau yog cov khoom sib txawv yooj yim xws li cov phaj, tuav, thiab lwm yam. Cov khoom siv tau zoo thiab cov khoom tsim tawm tsawg, thiab cov khoom lag luam tsis yooj yim los lav, Cov khoom siv hluav taws xob ntau thiab cov nqi khoom tsis tsuas yog txwv kev lag luam xav tau. thiab daim ntawv thov ntawm UHMW-PE resin hauv Suav teb, tab sis kuj ua rau 80-90 feem pua ​​​​ntawm cov khoom siv raw ntawm UHMW-PE resin nyob rau hauv Suav teb yuav tsum tau muag rau txawv teb chaws ntawm tus nqi qis.
