Siv lub nas ncoo ua piv txwv:
Piv nrog Teflon (polytetrafluoroethylene PTFE), cov khoom siv hauv cov nas ncoo ib txwm muaj, cov zaj duab xis polyethylene UPE uas muaj qhov hnyav molecular siab heev yog hnav-resistant dua. Cov khoom siv lubricating tus kheej ntawm UPE yog ze rau cov khoom siv Teflon. Tib lub sijhawm, los ntawm qhov pom ntawm tus nqi, qhov ceev ntawm cov zaj duab xis polyethylene UPE uas muaj qhov hnyav molecular siab heev yog qhov me me, thiab cov polyethylene polyethylene (UPE) uas muaj qhov hnyav molecular siab heev yog 50% qis dua Teflon hauv kev hloov pauv square. Yog li ntawd, cov zaj duab xis polyethylene (UPE) uas muaj qhov hnyav molecular siab heev tau maj mam hloov ferroazol ua thawj qhov kev xaiv rau cov ntaub ntawv raw ntawm ko taw rau cov chaw tsim khoom.
Daim ntawv thov hauv thaj teb ntawm daim kab xev:
Daim kab xev nplaum uas rhiab siab ua los ntawm zaj duab xis UHMWPE thiab muaj daim kab xev tso tawm. Piv nrog rau lwm cov kab xev nplaum uas siv zaj duab xis resin, nws qhov kev tiv taus kev cuam tshuam siab dua, kev tiv taus kev sib txhuam thiab kev ua kom lubrication zoo dua.

Kev Taw Qhia Txog UHMWPE:
Polyethylene hnyav molecular siab heev (UHMW-PE) yog hais txog polyethylene linear nrog qhov nruab nrab molecular hnyav ntau dua 1.5 lab. Vim nws qhov hnyav molecular siab heev (polyethylene ib txwm muaj 20,000 txog 300,000), UHMW-PE muaj kev ua tau zoo tsis sib xws piv rau polyethylene ib txwm thiab lwm yam yas engineering:
1) Kev tiv thaiv kev hnav siab heev, siab dua nylon 66 thiab PTFE 4 npaug, siab dua carbon hlau 6 npaug, qhov zoo tshaj plaws ntawm txhua cov khoom siv hluavtaws tam sim no.
2) Lub zog cuam tshuam siab heev, uas yog 2 npaug ntawm polycarbonate thiab 5 npaug ntawm ABS, thiab tuaj yeem tswj tau qhov muaj zog siab ntawm qhov kub ntawm cov kua nitrogen (-196 ℃).
3) Cov khoom siv zoo rau tus kheej, nws cov khoom siv lubricating zoo ib yam li PTFE, thiab qhov sib txhuam coefficient tsuas yog 0.07-0.11; nws tsuas yog 1/4-1/3 ntawm qhov sib txhuam coefficient ntawm hlau.
4) Tus nqi nqus hluav taws xob poob siab yog qhov siab tshaj plaws ntawm txhua yam yas, thiab qhov cuam tshuam txo suab nrov zoo heev.
5) Nws muaj kev ruaj khov tshuaj lom neeg siab thiab tuaj yeem tiv taus ntau yam corrosive media thiab organic media hauv qee qhov kub thiab txias thiab concentration.
6) Muaj peev xwm tiv thaiv kev nplaum, thib ob tsuas yog "Yas Vaj Ntxwv" PTFE.
7) Huv si thiab tsis muaj tshuaj lom, nws tuaj yeem siv rau hauv kev sib cuag nrog zaub mov thiab tshuaj.
8) Qhov ceev yog qhov tsawg tshaj plaws ntawm txhua yam yas engineering, 56% sib dua li PTFE thiab 22% sib dua li polycarbonate; qhov ceev yog 1/8 ntawm cov hlau, thiab lwm yam.
Vim yog qhov kev ua tau zoo tshaj plaws saum toj no, UHMW-PE raug hu ua "yas zoo kawg nkaus" los ntawm cov tebchaws European thiab Asmeskas thiab tau txais txiaj ntsig thiab siv dav hauv ntau yam lag luam.
