Kodi Ultra-High Molecular-Weight Polyethylene (UHMWPE) ndi chiyani?

Polyethylene ndiye pulasitiki yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi, koma mungadziwe bwanji ngati ndi ulusi woyenera kugwiritsa ntchito?Ganizirani za ultra-high-molecular-weight polyethylene (UHMWPE) - gawo laling'ono lolimba kwambiri la polyethylene lomwe lili ndi mphamvu zolemera 8-15 kuposa zitsulo.

Odziwika bwino ndi mayina amalonda a Spectra® ndi Dyneema®, mapulasitiki a UHMWPE ndi ulusi amagwiritsidwa ntchito makamaka pa:

· Kugwiritsa ntchito Ballistic (Zida Zankhondo, Zida Zankhondo)

· Masewera ndi zosangalatsa (kuuluka mumlengalenga, kusefukira, kukwera mabwato, kusodza)

· Zingwe ndi zingwe

· Kusamalira zinthu zambiri

· Porous mbali ndi fyuluta

· Makampani opanga magalimoto

· Makampani opanga mankhwala

· Makina opangira chakudya ndi zakumwa

· Zida zopangira migodi ndi mchere

· Zida zopangira

· Zida za zomangamanga ndi zosunthika

· Ntchito zokhudzana ndi mayendedwe, kuphatikiza ma tray amagalimoto, ma bin ndi ma hopper.

Monga mukuonera, UHMWPE ili ndi ntchito zosiyanasiyana kuyambira pakupanga kupita kuchipatala komanso pawaya ndi chingwe.Izi ndichifukwa cha mndandanda wautali wamapindu omwe amakwaniritsa zofunikira pazantchito zosiyanasiyana.

Ubwino wa UHMWPE ukuphatikiza, koma osalekezera ku:

· Kukana kwabwino kupsinjika komanso kusamva bwino pakusweka

· Kukana kuvala kwa abrasion - kugonjetsedwa ndi abrasion nthawi 15 kuposa carbon steel

· Ndi 40% Yamphamvu kuposa ulusi wa Aramid

· Imakana kwambiri ndi mankhwala - imatha kupirira kwambiri ma alkalis ndi asidi ambiri, zosungunulira organic, zochotsera mafuta komanso kuwononga ma electrolytic

· Si poizoni

· Zida zabwino kwambiri za dielectric

Kudzitchinjiriza pawekha - kokwana kocheperako (kofanana ndi PTFE)

· Kusadetsa

· FDA idavomerezedwa kuti igwiritsidwe ntchito pazakudya ndi zamankhwala

· Mphamvu yokoka yotsika - idzayandama m'madzi

Ngakhale izi zitha kumveka ngati chinthu choyenera, palinso zovuta zina zomwe muyenera kuzidziwa.UHMWPE ili ndi malo osungunuka otsika (297 ° mpaka 305 ° F) kuposa ma polima ambiri wamba, chifukwa chake siyoyenera kugwiritsa ntchito kutentha kwakukulu.Ilinso ndi coefficient otsika ya mikangano yomwe ingakhale drawback malinga ndi ntchito.UHMWPE ulusi ukhozanso kupanga "kukwawa" pansi pa katundu wokhazikika, womwe ndi njira yotalikitsa pang'onopang'ono ulusi.Anthu ena atha kuona mtengo wake kukhala woipa, komabe zikafika pa UHMWPE, zochepa ndizochulukirapo.Chifukwa cha mphamvu ya zinthuzi simudzafunika kugula monga momwe mungagule ndi zipangizo zina.
