UHMWPE ndiro uyePTFE ndiropari zvino ndiwo maviri anonyanya kushandiswa asiri esimbi mapurasitiki pamusika.Izvo zvinojairwa zvese zviri zviviri engineering epurasitiki mahwendefa ane corrosion resistance, self-lubrication uye low friction coefficient.Iwo akasiyana maitiro anoratidza kuti UHMWPE ndiro inonyanya kupfeka-inomira pane PTFE ndiro, asi yakakwirira tembiricha kuramba haina kunaka sePTFE ndiro.Tevere, ini ndichapfupikisa misiyano mikuru pakati pezviviri zvakadzama:
1. Pfeka kuramba: UHMWPE ndiro ine yakanakisa kupfeka kuramba, iyo yakakwira huremu hwemamorekuru, zviri nani kupfekedzwa kwekusagadzikana kwezvinhu.2. Friction coefficient: nekuti UHMWPE ine self-lubricating properties.Naizvozvo, inogona kushanda mukutsvedza kana kutenderera modhi isina mafuta ekuzora, ari nani pane simbi nemhangura mumamiriro ekuzora.
3. Mwero wekunyudzwa kwemvura yezvinhu: Ndiro yeUHMWPE ine mwero wakaderera wekutora mvura.Hainyatso kusveta mvura, haina kuzvimba mumvura, uye idiki pane naironi.4. Kemikari inopikisa: UHMWPE ndiro ine kugadzikana kwemakemikari yakakwirira, uye inogona kumira kushanda kwezvakasiyana-siyana zvinopisa media (asidhi, alkali, munyu) uye organic solvents yakadai seasidhi, alkali, munyu, nezvimwewo mukati meimwe tembiricha uye huwandu hwehuwandu.
5. Haina chepfu: UHMWPE ndiro haina kunhuhwirira, haina chepfu, haina kunhuwa, haipedzi, uye ine physiological cycling uye physiological adaptability.Iyo US Food and Drug Administration (FDA) uye United States Dhipatimendi rekurima (USDA) inobvumira kuti ishandiswe Iyo inoshandiswa panguva iyo inenge inosangana nechikafu nemishonga, saka yakakodzera maindasitiri anoda hutsanana hwepamusoro. mamiriro ezvinhu akadai sezvokudya nemishonga.
