UHMWPE ndi chidule cha Ultra High Molecular Weight PolyEthylene
UHMWPE ndi mzere, wotsika, chothandizira cha Ziegler, polyethylene resin.
Ndemanga
UHMWPE ili ndi kulemera kwambiri-avareji ya molekyulu yolemera, pafupifupi kuwirikiza kakhumi kuposa kulemera kwa maselo, High density polyethylene (HDPE) resins.
Chifukwa chakuchulukira kwambiri kwa mamolekyulu, UHMWPE ili ndi kukana kwambiri kwa ma abrasion komanso mphamvu yayikulu kwambiri ya pulasitiki iliyonse.
M'malo mwake, mbama yokhuthala ya 25mm (1 ″) imatha kuyimitsa pistol ya 0.38 caliber pa 150 mm (6 ″).
UHMWPE ndiye ma polima osavuta (PE) okhala ndi mawonekedwe apadera.
UHMWPE ili ndi mphamvu zogwira mtima kwambiri pakati pa ma polima ena a uinjiniya komanso kukwapula komanso kukana kuvala, kusagwirizana kwachilengedwe, kukana phokoso, kusamvana kochepa kwambiri, kukana kwamankhwala abwino komanso kukana kwamagetsi.
Kuphatikizidwa ndi kukana abrasion ndi kulimba, kutsika kocheperako kwa UHMWPE kumapereka malo odzitchinjiriza okha, osagwira ndodo.
Ma coefficients osasunthika komanso osinthika amakhala otsika kwambiri kuposa chitsulo komanso zida zambiri zamapulasitiki.
UHMWPE imatha kugwira ntchito ngati biomaterial, makamaka ngati zonse zolowa m'malo mwake monga mwachitsanzo prosthesis ya m'chiuno kapena opaleshoni ina iliyonse.
Zida zopangidwa kuchokera ku UHMWPE zimatha kutsitsa kwakanthawi kwakanthawi.
UHMWPE ili ndi kukhuthala kwakukulu ngakhale pamwamba pa kutentha kosungunuka.
Chifukwa chake, ndizovuta kupanga UHMWPE yoyera popanga jekeseni, kuumba nkhonya, kapena kutulutsa kokhazikika kwa screw.
Komabe, kuchepetsa mamasukidwe akayendedwe ndi kuwonjezera unyolo oligomers yochepa zingakhudze katundu wa mankhwala.
Kusakwanira bwino kumalepheretsa kugwiritsa ntchito UHMWPE.
Kuti atsogolere processing ake ntchito, UHMWPE pamodzi polyethylene (PE), polypropylene (PP), polyacrylate (PA), polycarbonate (PC), polyaniline (PANI), ndi zipangizo zina kusintha katundu wa ma polima amenewa.
High density polyethylene (HDPE) yakhala ikugwiritsidwa ntchito kwambiri m'makampani chifukwa cha kusinthika kwabwino, katundu wofunidwa komanso kutsika mtengo.
Kuphatikizika kwa UHMWPE/HDPE kwakopa chidwi kwambiri ngati chinthu chothandizira kukonza zolumikizana zamunthu chifukwa kuphatikiza koteroko kumalimbana bwino ndi kukwapula kuposa UHMWPE yabwino.
Kuphatikiza apo, HDPE ndi polymer yogwirizana ndi bio ndipo kupezeka kwa HDPE kumatha kupititsa patsogolo kusinthika kwa kuphatikiza kwa UHMWPE.
Zinthu zambiri za kuphatikiza kwa UHMWPE/HDPE zaphunziridwa, monga kukonza magwiridwe antchito, rheological properties, matenthedwe oxidative properties ndi machitidwe okhudzidwa.
Ngati UHMWPE sichidziwika kwambiri kunja kwa akatswiri, ntchito zake ndizodziwika bwino mumakampani, zamankhwala ndi chitetezo.
