Iyo UHMWPE ndiro inotora Ziegler mhando yepamusoro-inoshanda catalyst yakaderera-pressure synthesis nzira uye inodzorwa pamusoro pe1.5 kusvika 3 miriyoni sezvinodiwa.Tichifunga nezvekushatiswa kwekupisa kwemamorekuru panguva yekugadziriswa, high-density polyethylene ine viscosity avhareji yemamorekuru anopfuura miriyoni 1.7 inogona kugadziriswa kuita zvigadzirwa zvakasiyana kuti ive nekuita kwepamusoro.

1. High kupfeka kuramba: UHMWPE ndiro ine nani kupfeka kuramba pakati ose azvino einjiniya mapurasitiki uye inonyanya kubata maziso.Kukwirisa kwemamorekuru, ndiko kunowedzera kusapfeka zvinhu, kutopfuura zvinhu zvakawanda zvesimbi (senge kabhoni simbi, simbi isina tsvina, bhuronzi, nezvimwewo).Semuenzaniso, mapaipi eUHMW-PE ane hupenyu hwebasa hwe4-6 nguva dzemapombi esimbi pasi pemamiriro ekuora kwakasimba uye kupfeka kwakanyanya, uye kuwedzera kufambisa kwekufambisa ne20%.Inonyatsoratidza hukuru hwe "kuchengetedza simba, kuchengetedza kwezvakatipoteredza, hupfumi uye kushanda kwepamusoro".
2. Corrosion resistance: Haina corrosion mulye uye inogona kushandiswa muconcentrated hydrochloric acid pa80°C.Iine kushanda kwakadzikama mu75% yakanyanyisa sulfuric acid uye 20% nitric acid.Iyo zvakare yakagadzikana kumvura yegungwa uye mvura yekugezesa.
3. Yakanyanya kuderera coefficient of friction: The coefficient of static friction is 0.07, uye ine yakanaka self-lubricating properties.Iyo yakanaka kubereka, bushing, sliding block uye lining material.Kushandisa UHMWPE ndiro sechikamu chekukwesha chemidziyo haigone kungowedzera hupenyu hwekupfeka, asi zvakare kugamuchira mhedzisiro inochengetedza simba.
4. Impact resistance: The impact resistance inomira pekutanga pakati pemapurasitiki.Ingave iri simba rekunze rakasimba kana kushanduka kwemukati, zvakaoma kutsemuka.Simba rekuita rayo rakapetwa ka10 pane renylon 66, 20 nguva yepolyvinyl chloride, uye ka8 kupfuura yepolytetrafluoroethylene.Kunyanya munzvimbo dzakaderera tembiricha, simba rayo rekuita rinosvika pakukosha kwepamusoro, uye kuchinjika kwayo kunogona kupa masisitimu ekufambisa akachengeteka, vimbiso yakavimbika.
