Hauv kev ua haujlwm ntawm cov ntaub ntawv zoo, UHMWPE thiab nylon yog ob qho kev sib xws plastics siv hauv kev tsim tshuab, cov tshuab luam ntawv, thiab lwm yam kev lag luam kho mob, thiab lwm yam kev lag luam kho mob, thiab lwm yam kev lag luam kho mob, thiab lwm yam kev lag luam. Txawm li cas los xij, lawv cov yam ntxwv ua tau txawv txawv. UHMWPE muaj qhov tshwj xeeb hnav tsis kam thiab muaj zog cuam tshuam vim nws cov roj ultra siab, thaum nylon yog kev nyiam rau nws cov kev sib zog heev, thiab cov txheej txheem. Yog li, cov khoom twg yog qhov kev xaiv zoo hauv kev siv cov ntawv thov? Khaws kev nyeem ntawv raws li tsab xov xwm no muab kev tsom xam ua qhov tob tob ntawm UHMWPE vs nylon.
Dab tsi yog Uhmwpe?
UHMWPE (ultra-siab molecular hnyav polyethylene)yog ib daim ntawv siab tshaj ntawm polyethylene nrog qhov nruab nrab molecular hnyav xws li 1 {{{{}} lab thiab ib qho crystallinity ntawm txog li 85%. Nws nruj ntho entangled ntev-saw qauv grants nws tshwj xeeb hnav lub zog tiv taus thiab cuam tshuam muaj zog. Nrog lub ntom ntawm 0. 93-0.94 g \/ cm³, nws tau faib ua ib qho kev faib khoom.
Cov yam ntxwv tseem ceeb:
- Tsis tshua muaj coefficient ntawm kev sib txhuam
- Pom kev cuam tshuam tsis kam
- Superior tshuaj colrosion txawv heev (resistions acids zoo nkauj, alkalis, thiab ntsev)
- Ultra-tsawg dej nqus (<0.01%) and excellent dimensional stability
- Biocompe rau cov ntawv thov kho mob
Dab tsi yog nylon?
Nylon, ib qho ntawm qhov ntxov tshaj plaws enastics, suav nrog cov hom nylon 6, nylon 66, thiab nylon 6. Nws cov molecular muaj cov pab pawg sab nrauv, ua rau muaj kev kub ntxhov thiab kub ua hauj lwm. Txawm li cas los xij, nws yog hygroscopic, uas cuam tshuam rau qhov tseeb ntawm qhov tseeb. Crystallinity feem ntau yog li ntau ntawm 40-60%.
Cov yam ntxwv tseem ceeb:
- Siab txhua yam muaj zog thiab kev nruj
- Zoo nkees ua kom tsis kam thiab nkag tsis tau
- Siab tshav kub deflection kub
- Ntau yam kev ua txoj hauv kev (kev txhaj tshuaj molding, extrusion, tshuab moulding)
- Nqi Them Nqi Rau Pawg Ntau Lawm
