Tsis tas li ntawd xwb, pebDaim ntawv UHMWPEs muaj qhov sib txhuam tsawg heev, uas ua rau kev ua haujlwm du thiab ua haujlwm tau zoo. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov ntawv thov uas muaj kev txav mus los lossis kev sib hloov. Nws txo kev siv hluav taws xob, ua kom lub neej ntawm cov khoom ntev dua thiab txo qhov xav tau kev saib xyuas ntau zaus.
Hygroscopicity tuaj yeem yog teeb meem loj rau cov ntaub ntawv hauv cov ntawv thov uas raug rau ntau yam xwm txheej ib puag ncig. Nrog peb cov ntawv UHMWPE, kev nqus dej noo yog ib yam ntawm yav dhau los. Nws xoom hygroscopicity ua kom muaj kev ruaj khov txawm tias nyob rau hauv qhov chaw noo noo. Cov cuab yeej no kuj tiv thaiv kev loj hlob ntawm cov kab mob, ua rau pebDaim ntawv UHMWPEs tsim nyog rau ntau yam kev siv nyuaj xws li kev ua zaub mov.
Kev tiv thaiv xeb yog lwm yam tseem ceeb uas yuav tsum xav txog hauv kev lag luam uas muaj tshuaj lom neeg lossis cov tshuaj phem. Peb cov ntawv UHMWPE muaj kev tiv thaiv zoo rau ntau yam tshuaj lom neeg, cov kuab tshuaj thiab cov tshuaj corrosive. Qhov no ua kom muaj kev ruaj khov thiab kev ntseeg siab txawm tias nyob hauv qhov chaw nyuaj.
Tsis tas li ntawd xwb, cov vaj huam sib luag no muaj cov yam ntxwv zoo heev uas nqus suab. Hauv cov ntawv thov uas txo suab nrov yog qhov tseem ceeb, xws li cov tshuab conveyor lossis tshuab, peb cov ntawv UHMWPE zoo heev ntawm kev muab ib puag ncig ua haujlwm ntsiag to. Kev txo cov suab nrov tsis yog tsuas yog txhim kho cov xwm txheej ua haujlwm xwb tab sis kuj ua rau muaj kev tsim khoom ntau ntxiv.
Lub zog cuam tshuam ntawm peb cov ntawv UHMWPE yog qhov thib ob rau tsis muaj leej twg. Lawv tswj hwm kev ruaj khov txawm tias nyob hauv qab cov khoom hnyav lossis kev cuam tshuam, tiv thaiv kev puas tsuaj rau cov vaj huam sib luag lawv tus kheej lossis cov tshuab / khoom cuam tshuam. PebCov ntawv UHMWPEmuaj kev cuam tshuam zoo heev thiab kev tiv taus kev puas tsuaj rau kev ua tau zoo tshaj plaws thiab lub neej ntev.
Tsis tas li ntawd xwb, peb cov ntawv UHMWPE tseem khaws lawv cov khoom tseem ceeb txawm tias nyob hauv qhov kub thiab txias heev. Qhov kub ua haujlwm yog -200 ° C, tsim nyog rau kev siv qhov kub qis thiab siab. Qhov kev ruaj khov zoo no ua kom muaj kev ua haujlwm tas mus li thiab kev thaj yeeb nyab xeeb hauv txhua qhov chaw.
Ntawm peb lub tuam txhab, peb nkag siab txog qhov tseem ceeb ntawm kev hloov kho kom haum. Yog vim li ntawd peb thiaj muab cov ntawv UHMWPE ntau yam xim, qhov loj me thiab tuab. Txawm hais tias koj xav tau xim tshwj xeeb rau kev txheeb xyuas lossis qhov tuab tshwj xeeb kom ua tau raws li qhov yuav tsum tau ua, peb tau npog koj.
Rau cov ntawv UHMWPE, peb lub tuam txhab yog koj qhov kev daws teeb meem ib qho. Nrog peb txoj kev cog lus rau qhov zoo, kev xaiv kho kom haum, thiab kev pabcuam zoo rau cov neeg siv khoom, peb lav qhov kev txaus siab ntawm cov neeg siv khoom. Tiv tauj peb hnub no los tham txog koj cov kev xav tau tshwj xeeb thiab nrhiav qhov zoo tshaj plawsDaim ntawv UHMWPEkev daws teeb meem rau koj txoj kev lag luam.
