2. Lub Zog Cuam Tshuam Zoo Kawg Nkaus - Daim ntawv UHMWPE qhia txog lub zog cuam tshuam zoo kawg nkaus, rau npaug ntau dua li ABS (Acrylonitrile Butadiene Styrene) - ib qho yas engineering uas siv ntau. Cov khoom no muaj txiaj ntsig tshwj xeeb hauv qhov chaw kub qis uas lwm cov ntaub ntawv feem ntau yuav tawg yooj yim. Nrog daim ntawv UHMWPE, koj tuaj yeem paub tseeb tias koj cov khoom siv yuav tiv taus kev cuam tshuam hnyav thiab tswj nws cov qauv kom ruaj khov.
3. Muaj zog tiv taus corrosion - Lwm yam khoom tseem ceeb ntawmDaim ntawv UHMWPEyog nws txoj kev tiv taus corrosion zoo heev. Tsis zoo li cov hlau uas tuaj yeem xeb lossis corrode, UHMWPE daim ntawv tseem tsis cuam tshuam los ntawm ntau yam tshuaj lom neeg, kua qaub, thiab alkalis. Qhov no ua rau nws yog qhov kev xaiv zoo heev rau cov ntawv thov uas raug rau cov tshuaj corrosive yog qhov tsis zam, xws li kev ua tshuaj lom neeg, kev kho dej khib nyiab, thiab cov chaw nyob hauv hiav txwv.
4. Kev Siv Lubricating Tus Kheej - Daim ntawv UHMWPE muaj cov khoom siv lubricating tus kheej tshwj xeeb, ua rau nws ua haujlwm tau zoo thiab txo qhov kev sib txhuam yam tsis tas yuav siv cov roj nplua nyeem ntxiv. Qhov no tsis yog tsuas yog txhim kho kev ua haujlwm zoo xwb tab sis kuj txo qhov yuav tsum tau saib xyuas, vim tias tsis tas yuav tsum siv cov roj nplua nyeem dua tas li. Cov khoom siv lubricating tus kheej ntawm daim ntawv UHMWPE ua kom ntseeg tau tias muaj kev ua haujlwm zoo thiab ua kom lub neej ntawm koj cov khoom siv ntev dua.
5. Kev Tiv Thaiv Kub Qis - Daim ntawv UHMWPE muaj kev tiv thaiv zoo rau qhov kub qis. Nws tuaj yeem tiv taus qhov chaw txias heev, nrog rau qhov kub qis tshaj plaws mus txog -170 degrees Celsius. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv cov xwm txheej khov, xws li kev ua zaub mov, kev khaws cia txias, thiab kev tshawb nrhiav polar.
6. Tiv thaiv kev laus -Daim ntawv UHMWPEqhia tau tias nws tiv taus kev laus zoo heev. Txawm tias nyob rau hauv lub hnub ci ib txwm muaj, nws tuaj yeem tswj nws txoj kev ncaj ncees thiab kev ua tau zoo txog li 50 xyoo yam tsis muaj cov cim qhia txog kev laus lossis kev puas tsuaj. Qhov kev ruaj khov tshwj xeeb no ua rau daim ntawv UHMWPE ua qhov kev daws teeb meem ntev uas tsim nyog thiab txhim khu kev qha rau ntau yam kev siv.
7. Muaj Kev Nyab Xeeb, Tsis Muaj Qab, Tsis Muaj Tshuaj Lom - Daim ntawv UHMWPE yog cov khoom siv muaj kev nyab xeeb thiab tsis muaj tshuaj lom. Nws siv dav hauv kev lag luam uas xav tau kev huv huv thiab kev nyab xeeb, xws li kev ua zaub mov, tshuaj, thiab cov khoom siv kho mob. Ntxiv mus, daim ntawv UHMWPE tsis muaj qab, ua kom ntseeg tau tias nws tsis cuam tshuam rau qhov zoo lossis saj ntawm cov khoom noj.
Xaus lus,Daim ntawv UHMWPEmuaj ntau yam khoom zoo heev uas ua rau nws yog qhov kev daws teeb meem yas zoo tshaj plaws rau ntau yam kev siv. Nws tiv taus kev hnav, lub zog cuam tshuam zoo heev, tiv taus corrosion muaj zog, muaj peev xwm ua kom nws tus kheej lubricating, tiv taus kub tsawg, tiv taus kev laus, thiab cov yam ntxwv kev nyab xeeb ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov engineers thiab cov chaw tsim khoom. Txawm tias koj xav tau cov khoom siv rau cov tshuab hnyav, cov khoom sib xyaw ua ke, lossis cov chaw huv si,Daim ntawv UHMWPEyuav tshaj qhov koj xav tau. Nqis peev rau hauv daim ntawv UHMWPE hnub no thiab paub txog cov txiaj ntsig tsis muaj qhov sib piv uas nws muab.
