Filimu ya UHMW Polyethylene ili ndi kukana kwambiri kwa abrasion, kupitilira kukana kwachitsulo.Kuphatikizidwa ndi kukana kwamphamvu kwamankhwala komanso kukangana kochepa kumapangitsa UHMW kukhala chida chauinjiniya chosunthika kwambiri pamagwiritsidwe ntchito ambiri ovuta.Kuterera ngati polymer® Fluoropolymer, koma kupsa mtima kwambiri & kusamva kuvala.Ma polima a UHMW ali ndi kulemera kwa ma molekyulu pafupifupi nthawi 10 kuposa ma utomoni wamba wa polyethylene.Kulemera kwa mamolekyulu apamwamba kumapatsa UHMW Polymers kuphatikiza kwake kwapadera kwa mawonekedwe Ntchito: Malo amkati ndi akunja amadzi amchere, mankhwala, mafuta ndi ma hydraulic hoses, pansi pa skis ndi matabwa a chipale chofewa, zomangira za chute kuti achepetse kugundana ndi kuvala.
Kanema wamalonda wamalonda wa polyethylene (UHMWPE) wokhala ndi mawonekedwe apamwamba a uniaxial1 adaphunziridwa panthawi yosungunuka ndi crystallisation ndikutha kwanthawi kwa 30s kuti azindikire njira zamakristali.
Zinapezeka kuti isotropic crystallization imachitika nthawi iliyonse pamene kusungunuka kwatenthedwa kufika 140◦C kapena pamwamba.Kuwala kokhazikika kumachitika, ngati kusungunuka kumasungidwa pa 138◦C kapena pansi.Kutentha koyenera kusungunuka kumawoneka ngati 136◦C.Pa kutentha kumeneku mawonekedwe a semicrystalline nanostructure a filimu yoyambirira amafufutika, pamene kukumbukira kukumbukira kwa kusungunuka kumasungidwa.Komanso, crystallization ya isothermal singayambike pa kutentha kwa 110◦C ndi kupitirira apo.Pa kutentha kwa 105◦C crystallization yokhazikika imayamba pambuyo pa 2.5 min.Lamellae yokhala ndi makulidwe ocheperako pang'onopang'ono amakula munthawi yotentha ya mphindi 20.
Panthawi ya crystallization yosagwirizana ndi isothermal (kuzizira: 20◦C / min) tinthu tating'ono ta crystalline tokhala ndi mgwirizano woyandikana nawo timapangidwa.Chifukwa chake njira zopangira kristalo ndizofanana ndi zomwe zimapezeka ndi zida zina za polyethylene zokhala ndi unyolo wokwanira wotsekeka womwe udaphunziridwa kale, kupatula kuzizira kwambiri komwe kumafunikira kuyambitsa kutenthetsa kwa isothermal.
Kusanthula deta mu malo enieni pogwiritsa ntchito multidimensional CDF kwachitika.Pakusungunuka kwa zinthuzo pafupifupi makulidwe a zigawo za crystalline amakhalabe (27 nm), pamene nthawi yayitali ikuwonjezeka kwambiri kuchokera ku 60 nm kufika ku 140 nm.Chifukwa kusanthula kumasonyeza kuti ngakhale choyambirira nanostructure imayang'aniridwa ndi malumikizano oyandikana nawo okha izi zikutanthauza kuti kukhazikika kwa lamella kumawonjezeka monyanyira monga ntchito ya mtunda kwa oyandikana nawo.Ngakhale mawonekedwe oyambilira akuwonetsa lamellae yokulirapo, madera omwe adasinthidwanso siatali kuposa mtunda wapakati pawo mumayendedwe a fiber s3.
Mapulogalamuwa akuphatikizanso ma conveyor, njanji zowongolera, ma chute liner, maupangiri a maunyolo, ma drawer glide ndi kuchepetsa phokoso.Wabwino abrasion ndi kuvala kukana.
