1. kukana kwambiri kuvala
Kulemera kwa machubu apamwamba kwambiri mpaka kupitilira 2 miliyoni, index yovala ndiyocheperako, zomwe zimapangitsa kuti izi zitheke kwambiri kukana kutsetsereka.Kukana kuvala ndi nthawi 6.6 kuposa zitsulo wamba aloyi ndi 27.3 nthawi kuposa zitsulo zosapanga dzimbiri.Ndi 17.9 nthawi za phenolic resin, 6 nthawi za nayiloni, 4 nthawi za polyethylene, kuwongolera kwambiri moyo wautumiki wa payipi.
2. kukana kwakukulu
Mphamvu yamphamvu yapaipi ya uHMW ndiyokwera kwambiri pakati pa mapulasitiki a engineering omwe alipo.Zida zambiri zimasweka, kusweka, kusweka kapena kutopa kwapamtunda pansi pa kuphulika kwakukulu kapena mobwerezabwereza.Mankhwalawa molingana ndi muyezo wa GB1843, kuyesa kwa mtengo wa cantilever kuti asawonongeke, kumatha kupirira kukhudzidwa kwamphamvu kwakunja, kulemetsa kwamkati, kusinthasintha kwamphamvu.
3. kukana dzimbiri
Uhmw-pe ndi mtundu wamagulu odzaza maselo amagulu, kotero kukhazikika kwake kwamankhwala ndikokwera kwambiri, chinthucho chimatha kukana kukokoloka kwa zinthu zamphamvu zamankhwala, kuwonjezera pa asidi ena amphamvu pa kutentha kwakukulu kumakhala dzimbiri pang'ono, mu zina zamchere, asidi ndi osati dzimbiri.Itha kugwiritsidwa ntchito mu hydrochloric acid yokhala ndi ndende zosakwana 80%.Ndiwokhazikika mu sulfuric acid ndi ndende zosakwana 75% ndi nitric acid ndi ndende zosakwana 20%.
4. bwino kudzipaka mafuta
Chifukwa chubu la UHMWPE lili ndi zinthu za waxy, ndipo mafuta ake ndiabwino kwambiri.Mkangano wapakati (196N, 2 hours) ndi 0.219MN/m (GB3960).Kuthamanga kwake kumakhala kopambana kuposa chitsulo chopaka mafuta kapena mkuwa.Makamaka m'malo ovuta, fumbi, silt ndi malo ambiri, ntchito yake yamafuta owuma imawonetsedwa bwino.Sikuti amatha kuyenda momasuka, ndikuteteza chogwirira ntchito kuti zisavale kapena kupsinjika.
5. wapadera otsika kutentha kukana
Chitoliro chokwera kwambiri cha polyethylene chimakhala ndi kukana kwa kutentha kochepa kwambiri, ndipo kukana kwake komanso kukana kuvala sikunasinthe pa madigiri 269 Celsius.Pakali pano ndi pulasitiki yokhayo yauinjiniya yomwe imatha kugwira ntchito pakatentha pafupifupi ziro.Pa nthawi yomweyo, uHMWPE chitoliro ali lonse kutentha kulolerana, amene angathe kugwira ntchito mu kutentha kwa -269 ℃ 80 ℃ kwa nthawi yaitali.
6. Sikophweka kukulitsa
Chitoliro cha Uhmwpe chili ndi malo abwino osamata komanso kutha kwa chitoliro chapamwamba chifukwa cha kugunda kwake kocheperako komanso kusakhala ndi polarity.Zida zomwe zilipo nthawi zambiri zimakhala pakati pamtengo wa PH pamwamba pa 9, koma chitoliro cha uHMWPE sichimakula, chomwe chili chofunikira kwambiri pamakina otulutsa phulusa la malasha m'mafakitale opangira magetsi.M'mafuta opanda mafuta, matope ndi mapaipi ena oyendetsa nawonso ndi abwino kwambiri.
7. moyo wautali wa alumali
Uhmwpe ali ndi ma jini opanda unsaturated ochepa m'maselo ake, ndipo kutopa kwake kumaposa nthawi 500,000.Ili ndi kukana kwabwino kwambiri kwapang'onopang'ono komanso kukana kupsinjika kwa chilengedwe.4000H, kuposa 2 nthawi PE100, m'manda kwa zaka 50 kapena apo, akhoza kukhalabe oposa 70% ya katundu makina.
8. Easy unsembe
Koposa mkulu maselo kulemera polyethylene (UHMW—-PE) chitoliro chitoliro wagawo kutalika gawo limodzi mwa magawo asanu ndi atatu a kulemera chitoliro zitsulo, kuti Mumakonda ndi katundu, mayendedwe, unsembe ndi yabwino, ndipo akhoza kuchepetsa ntchito mphamvu ya ogwira ntchito, UHMW-PE chitoliro ali amphamvu odana ndi ukalamba, zaka 50 si kophweka kukalamba.Kaya erection pansi, kapena kukwiriridwa mobisa kungakhale.Kaya kuwotcherera kapena kulumikizidwa kwa flange kutha kukhazikitsidwa, kotetezeka, kodalirika, mwachangu komanso kosavuta, kopanda dzimbiri, ntchito ndi kupulumutsa ntchito, kumawonetseratu kugwiritsa ntchito payipi ya uHMWPE "kupulumutsa mphamvu, kuteteza chilengedwe, chuma ndi kothandiza" kupambana.
9. Zina
Ultra mkulu maselo kulemera polyethylene chitoliro ndi mphamvu mayamwidwe, mayamwidwe phokoso, odana malo amodzi, pakompyuta kutchinga luso, osati mayamwidwe madzi, kuwala yokoka, Machining zosavuta, mitundu ndi makhalidwe ena otchuka.
