Ultra-siab molecular hnyav polyethylene (UHMWPE)yog ib qho kev kawm siab thermoplastic khoom siv engineering khoom. Nws cov khoom tseem ceeb yog sau tau raws li hauv qab no:
UHMWPE cov ntawv txheeb: Txheej txheem cej luam ntawm cov yam ntxwv
Tsawg-kub nyuaj:
UHMWPE khaws nws cov tawv txawm nyob hauv ib puag ncig tsawg. Nws tuaj yeem tiv taus kev cuam tshuam sab nraud tsis muaj kev nyiag lossis tawg yooj yim.
Kev Cuam Tshuam:
Ntawm qhov kub uas muaj tsawg li -40 degree, UHMWPE cov khoom pov thawj zoo tsis kam. Nws tuaj yeem ua kom muaj kev cuam tshuam tseem ceeb hauv qab tsis muaj mob uas tsis muaj kev puas tsuaj.
Neeg kho tshuab zog:
UHMWPE kav tswj kav ib theem ntawm cov tshuab muaj zog txawm tias nyob rau hauv ultra-tsawg kub, ua rau lawv haum rau kev thov nitrogen thauj mus los pipelines.
Tsawg coefficient ntawm kev sib txhuam:
UHMWPE cov ntawv muaj cov coefficient ntawm kev sib txhuam, tso cai rau lawv ua haujlwm raws li kev ua kom qhuav lossis tsis zoo lubricated zoo.
Zoo heev tshuaj muaj peev xwm:
UHMWPE ua rau pom kev zoo rau cov tshuaj feem ntau. Nws tsis yooj yim corroded los yog degraded, ua rau nws ua haujlwm ncaj qha rau ntau yam ntawm ib puag ncig tshuaj tsis muaj kev ua tiav vim yog tshuaj lom neeg cov tshuaj tiv thaiv.
