UHMWPE phaj thiab PTFE phaj yog tam sim no ob feem ntau siv cov yas uas tsis yog xim hlau ntawm lub khw.Cov yam ntxwv ntawm ob qho tib si yog engineering yas daim hlau nrog corrosion kuj, nws tus kheej lubrication thiab tsis tshua muaj kev sib txhuam coefficient.Cov yam ntxwv sib txawv qhia tau tias UHMWPE phaj yog hnav-tiv taus ntau dua li PTFE phaj, tab sis qhov kub thiab txias tsis zoo li PTFE phaj.Tom ntej no, kuv yuav xaus qhov sib txawv tseem ceeb ntawm ob qhov kev nthuav dav:
UHMWPE phaj thiabPTFE phajTam sim no yog ob qho khoom siv uas tsis yog hlau siv ntau tshaj plaws ntawm kev ua lag luam.Cov yam ntxwv ntawm ob qho tib si yog engineering yas daim hlau nrog corrosion kuj, nws tus kheej lubrication thiab tsis tshua muaj kev sib txhuam coefficient.Cov yam ntxwv sib txawv qhia tau tias UHMWPE phaj yog hnav-tiv taus ntau dua li PTFE phaj, tab sis qhov kub thiab txias tsis zoo li PTFE phaj.Tom ntej no, kuv yuav xaus qhov sib txawv tseem ceeb ntawm ob qhov kev nthuav dav:
1. Hnav tsis kam: UHMWPE phaj muaj kev hnav zoo heev, qhov hnyav dua molecular, qhov zoo dua hnav tsis kam ntawm cov khoom.2. Kev sib txhuam coefficient: vim UHMWPE muaj nws tus kheej lubricating zog.Yog li ntawd, nws muaj peev xwm ua hauj lwm nyob rau hauv zawv zawg los yog rotating hom yam tsis muaj lubricating roj, uas yog zoo dua li hlau thiab tooj liab nyob rau hauv lubricating tej yam kev mob.
3. Kev nqus dej ntawm cov khoom siv: UHMWPE phaj muaj qhov nqus dej tsawg heev.Nws tsis nqus dej, tsis o hauv dej, thiab me dua li nylon.4. Tshuaj tiv thaiv: UHMWPE phaj muaj cov tshuaj lom neeg ruaj khov, thiab tuaj yeem tiv taus qhov kev ua ntawm ntau yam corrosive media (acid, alkali, ntsev) thiab cov kuab tshuaj organic xws li kua qaub, alkali, ntsev, thiab lwm yam nyob rau hauv qhov kub thiab txias ntau yam.
5. Tsis muaj tshuaj lom: UHMWPE phaj tsis muaj ntxhiab tsw, tsis muaj tshuaj lom, tsis muaj ntxhiab tsw, tsis muaj corrosive, thiab muaj lub cev muaj zog thiab kev hloov pauv ntawm lub cev.Lub US Food and Drug Administration (FDA) thiab United States Department of Agriculture (USDA) tso cai rau nws siv Nws yog siv nyob rau hauv lub sij hawm uas nws yog nyob rau hauv kev sib cuag nrog cov zaub mov thiab tshuaj, yog li nws yog tsim nyog rau kev lag luam uas yuav tsum tau muaj siab huv si. tej yam kev mob xws li zaub mov thiab tshuaj.
