UHMWPE yog hais txog ultra-siab molecular hnyav polyethylene, HDPE hais txog high-density polyethylene, ob qho tib si cov ntaub ntawv yog rau engineering plastics, thiab lawv qhov zoo
1. Cov hnav tsis kam yog qhov siab tshaj plaws ntawm cov yas, thiab qhov loj dua qhov hnyav molecular, siab dua hnav tsis kam thiab cuam tshuam ntawm cov khoom;
2. Qhov cuam tshuam lub zog yog qhov muaj txiaj ntsig zoo tshaj plaws ntawm cov yas uas twb muaj lawm, txawm tias nws tau muab pov rau ntawm 70 degrees nrog rau lub zog muaj zog;
3. Lubricating tus kheej;
4. Cov dej nqus dej tsawg kawg nkaus. Yog li ntawd, nws lub cev thiab txhua yam khoom muaj kev ywj pheej ntawm cov av noo nyob rau hauv kev ua haujlwm siv;
5. Chemically ruaj khov, nyob rau hauv ib tug tej yam kub thiab concentration ntau yam, nws muaj peev xwm tiv taus corrosion ntawm ntau yam corrosive media xws li acid, alkali, ntsev thiab organic solvents 6. Tasteless, non-toxic, tsw, non-corrosive, nrog yeej lub voj voog thiab physiological adaptability.
7. Tsis-adhesion;
8. Thaum qhov hnyav molecular tshaj 500, 000, embrittlement kub poob mus rau 140 degrees. Ultra-siab molecular hnyav polyethylene tuaj yeem siv tau raws li kev ua haujlwm ntawm cov kua nitrogen, thiab nws qhov kev siv kub tuaj yeem ncav cuag tsawg dua -269 degrees, thiab nws tseem muaj qee yam kev siv zog.
