1. Kev sib txhuam kev ua haujlwm
UHMWPE muaj kev hnav zoo heev, yog li UHMWPE fiber ntau kuj muaj kev hnav zoo heev. Abrasion kuj tseem ceeb heev rau daim ntawv thov ntawm UHMWPE fiber nyob rau hauv cov hlua thiab cov hnab looj tes txiav-resistant, uas txiav txim siab lub durability thiab kua muag kuj ntawm cov khoom thiab yog ib qho tseem ceeb cuam tshuam rau lub neej kev pab cuam ntawm cov khoom. Ob qho tib si static thiab dynamic kev sib txhuam coefficients ntawm UHMWPE fibers yog qis dua cov aramid fibers. Vim tias qhov siab ntawm crystallinity thiab kev taw qhia ntawm UHMWPE fibers thiab thaj tsam me me ntawm cov saw hlau molecular, nws nthuav tawm me me coefficient ntawm kev sib txhuam. Ntxiv nrog rau kev coj tus cwj pwm ntawm cov fibers tiv thaiv kev sib cuag, kev sib txhuam ntawm cov fibers nyob rau hauv cov ntaub fibers kuj tseem ceeb rau daim ntawv thov.
2. Tshuaj stability
UHMWPE yog cov polymer nrog cov qauv molecular yooj yim tshaj plaws. Muaj tsuas yog covalent ib daim ntawv cog lus hauv cov saw hlau molecular thiab tsis muaj pawg polar. Yog li, UHMWPE fibers tsis rhiab rau hydrolysis. Tib lub sijhawm, UHWMPE fiber ntau muaj crystallinity siab thiab qib siab ntawm molecular saw orientation, thiab muaj tshuaj lom neeg ruaj khov. Tom qab ua yeeb yam hauv acid, alkali thiab ntsev tov rau ib lub hlis, lub zog tuav tus nqi ntawm high-strength polyethylene fiber ntau yog siab heev.
3. Ceev ceev
Qhov ceev ntawm UHNVPE fiber ntau ntawm 293K yog hais txog 960-980kg / ㎡, thiab nws qhov ceev tus nqi yog cuam tshuam nrog crystallinity, uas nce me ntsis nrog qhov nce ntawm crystallinity. Qhov ceev ntawm UHMWPE fiber ntau yog 2/3 ntawm cov aramid fiber (aramid fiber) thiab 1/2 ntawm cov high-strength thiab high-modulus carbon fiber. UHMWPE fibers muaj kev vibration damping zoo heev.
