1. Hnav tsis kam
Kev hnav tsis kam ntawm UHMWPE qib siab dua li ntawm cov yas, thiab tshaj li ntawm qee cov hlau. Kev hnav tsis kam ntawm UHMWPE yog piv nrog lwm cov ntaub ntawv. Nws tuaj yeem pom tau tias piv nrog lwm cov yas yas, cov tshuaj khib nyiab ntawm UHMWPE tsuas yog 1/5 ntawm PA66, 1/10 ntawm HEPE thiab PVC; piv nrog hlau, nws yog 1/7 ntawm carbon steel thiab 1/ ntawm tooj dag. 27. Qhov kev hnav zoo li no ua rau nws nyuaj rau kev sim nws qhov hnav tsis kam los ntawm cov qauv yas hnav, yog li cov khoom siv tshuaj khib nyiab yog tsim tshwj xeeb. Kev puas tsuaj ntawm UHMWPE yog proportional rau qhov hnyav molecular. Qhov siab dua qhov hnyav molecular, qhov zoo dua qhov kev puas tsuaj.
2. Tus kheej -lubricating
UHMWPE muaj cov coefficient tsawg heev ntawm kev sib txhuam ({{0}}.05 txog 0.11), yog li nws muaj tus kheej zoo heev -lubricating zog. Table 1 yog qhov sib piv ntawm kev sib txhuam ntawm UHMWPE thiab lwm yam khoom siv yas. Raws li pom tau los ntawm Table 1, qhov kev sib txhuam tsis zoo ntawm UHMWPE yog 1/2 ntawm PA66 thiab POM nyob rau hauv cov dej lubrication, thiab nws tsuas yog thib ob rau polytetrafluoroethylene (PTFE) nrog tus kheej zoo tshaj plaws{10}}lubrication hauv yas nyob rau hauv uas tsis yog{11}}lubricated tej yam kev mob. ; Thaum nws ua haujlwm hauv zawv zawg lossis tig daim ntawv, lubricity zoo dua li cov hlau thiab tooj dag nrog cov roj lubricating. Yog li ntawd, nyob rau hauv lub teb ntawm tribology, UHMWPE yog lub npe hu ua ib tug zoo tagnrho kev sib txhuam khoom nyob rau hauv cov nqe lus ntawm tus nqi / kev ua tau zoo.
3. Tshuaj tiv thaiv
UHMWPE muaj cov tshuaj tiv thaiv zoo heev, ntxiv rau qhov muaj zog oxidizing acid, nws tuaj yeem tiv taus ntau yam corrosive media (acid, alkali, ntsev) thiab cov organic media (tshwj tsis yog tshuaj yej hnyav) nyob rau hauv qhov kub thiab txias ntau yam. Nws tau muab tso rau hauv 80 hom organic solvents ntawm 20 degree thiab 80 degree rau 30 hnub, thiab tsis muaj qhov tshwm sim txawv txav ntawm qhov chaw, thiab lwm yam khoom ntawm lub cev yuav luag tsis hloov.
4. cuam tshuam lub zog nqus
UHMWPE muaj qhov cuam tshuam zoo ntawm lub zog nqus, qhov cuam tshuam lub zog nqus tus nqi yog qhov siab tshaj plaws ntawm tag nrho cov yas, yog li lub suab nrov damping kev ua tau zoo heev, thiab nws muaj lub suab zoo heev.
5. Tsawg kub tsis kam
UHMWPE muaj qhov ua tau zoo ntawm qhov kub thiab txias thiab tseem ua rau cov kua helium kub (-269 degree), yog li nws tuaj yeem siv los ua cov khoom siv hluav taws xob qis hauv kev lag luam nuclear.
6. Hygienic thiab tsis yog - lom
UHMWPE yog huv si thiab tsis yog - lom, ua raws li cov qauv ntawm Nyiv Hygiene Association, thiab tau pom zoo los ntawm US Food Administration thiab US Department of Agriculture rau kev sib cuag nrog zaub mov.
7. Tsis nplaum
Lub peev xwm adsorption ntawm UHMWPE yog qhov tsis muaj zog heev, thiab nws txoj kev tiv thaiv -adhesion muaj peev xwm yog thib ob tsuas yog PTFE, uas yog qhov zoo tshaj plaws uas tsis yog - lo rau hauv cov yas, yog li qhov saum npoo ntawm cov khoom tsis yooj yim rau lo rau lwm yam ntaub ntawv.
8. Kev nqus dej tsawg
Tus nqi nqus dej ntawm UHMWPE tsawg heev; feem ntau tsawg dua 0.01 feem pua , tsuas yog 1 feem pua ntawm PA66, yog li nws feem ntau tsis tas yuav qhuav ua ntej molding.
9. Ceev ceev
Table 2 yog qhov sib piv ntom ntom ntawm UHMWPE thiab lwm yam yas yas. Nws tuaj yeem pom los ntawm Table 2 tias qhov ceev ntawm UHMWPE yog qis dua li ntawm tag nrho lwm yam khoom siv yas, feem ntau 56 feem pua qis dua PTFE, 33 feem pua qis dua POM, thiab 30 feem pua qis dua PBTP, yog li nws cov khoom yog hnyav heev.
10. Tensile zog
Vim tias UHMWPE muaj cov yam ntxwv tsim nyog ntawm kev taw qhia tensile, nws muaj qhov tsis sib xws ultra- siab tensile lub zog, yog li ultra{{1} siab elastic modulus thiab lub zog fibers tuaj yeem tau los ntawm txoj kev gel spinning, thiab nws lub zog tensile yog siab li 3-3.5GPa, tensile elastic modulus siab li 100-125GPa; qhov tshwj xeeb fiber ntau lub zog yog qhov siab tshaj plaws ntawm tag nrho cov fibers uas tau ua lag luam kom deb li deb, 4 zaug loj dua carbon fiber, 10 npaug loj dua steel hlau, thiab 50 feem pua loj dua aramid fiber.
11. Lwm yam khoom
UHMWPE kuj muaj cov khoom siv hluav taws xob zoo tshaj plaws, kev tiv thaiv ib puag ncig kev ntxhov siab dua li HDPE, kev qaug zog zoo dua thiab r-ray resistance dua HDPE.
