Mēnā kei te rapu koe i tētahi rauemi pono, pakari hoki mō ngā mahi e pāngia ana e te kakahu me te pānga nui, kaua e titiro atu ki tua atu i te pepa UHMWPE. Ko te UHMWPE he whakarāpopototanga mō te Ultra High Molecular Weight Polyethylene, ā, he pepa kirihou e tuku ana i te mahi tino pai i roto i ngā āhuatanga tino kino. Nā tōna huinga ahurei o ngā āhuatanga, kei te piki haere te rongonui o tēnei rauemi i roto i ngā momo ahumahi.
Ko tētahi o ngā āhuatanga matua o te pepa UHMWPE ko tōna ātete nui ki te pakū me te pānga. Ahakoa he kakahu reti tonu, he kakahu waku rānei nā ngā wāhanga whakarewa, ka taea e tēnei rauemi te tu atu. Mai i ngā arai o te hāpara me te hopper ki ngā kaikawe, ki ngā wāhanga rānei, ki ngā papa kakahu, ki ngā reera mīhini, ki ngā mata pānga me ngā reera, ko ngā pepa UHMWPE te whiringa tuatahi.
Engari ehara i te mea koinā anake! He maha atu ngā painga o te pepa UHMWPE e waiho ana hei rauemi tino pai mō ngā mahi hangarau. Tuatahi, he ātete ki te UV, arā, ka taea e ia te tu atu ki te hihi o te rā mō te wā roa, me te kore e pirau. Nā tēnei ka pai mō te whakamahi i waho, kia roa ai te ora me te pono i ngā āhuatanga huarere katoa.
Ko tētahi atu āhuatanga rongonui oRau UHMWPEhe tino pai te mahi miihini. Nā te iti o te tauwehenga waku me te ngāwari o te tukatuka ka waiho hei rauemi maha mō ngā kaupapa hangarau. Ahakoa te tapahi, te keri, te hanga rānei, ka taea te tukatuka ngāwari i ngā rau UHMWPE kia tutuki ai ngā whakaritenga motuhake, ka penapena i te wā me te kaha.
Hei tāpiritanga, tata kore rawa ngā rau UHMWPE e pāngia e ngā whakaekenga matū. He tino ātete ki te whānuitanga o ngā matū, ngā waikawa me ngā kawakore, e whakapūmau ana i tōna kounga ahakoa i roto i ngā taiao kino. Nā tēnei ka tino pai mō ngā tono e pāngia ana e ngā matū waikura.
Haunga te ātete matū,Rau UHMWPEKāore hoki ngā rau e ārai, e piri hoki. Ko te tikanga o tēnei, he iti ake te tūponotanga o te piri o ngā rauemi me ngā paru ki tōna mata, ā, ka maeneene ake te mahi me te whakaiti i ngā whakaritenga tiaki. Ahakoa he witi, he waro, he rauemi kē atu rānei, ka whakarite ngā rau UHMWPE i te rere pai rawa atu, ā, ka ārai hoki i te aukati.
Hei tāpiritanga, he tino pai hoki ngā āhuatanga hiko o te pepa UHMWPE. He kaha teitei tōna ki te ārai i te hiko, ā, he mea tino pai hei ārai i ngā mahi hiko me ngā mahi hiko. Nā te iti o te mimiti makuku me ōna āhuatanga ārai hiko pai, he mea pono hei whiringa mō ngā momo taiao wero.
Ko tētahi atu painga o te pepa UHMWPE ko tōna kaha ki te mahi pai i ngā pāmahana makariri. Kāore i rite ki ētahi rauemi ka pakarukaru i te makariri rawa, ka mau tonu te pakari me te ngāwari o te pepa UHMWPE ahakoa i raro i te kore. Nā tēnei ka pai mō ngā tono e hiahia ana ki te mahi pai ake i ngā taiao makariri.
Mō te ātete ki te pāmahana,Rau UHMWPEko te pāmahana whakahaere mōrahi he 80°F. Ko te tikanga ka taea e ia te tu atu i ngā pāmahana teitei me te kore e kitea he rerekētanga, he rerekētanga rāneite pirau. Heoi anō, me whai whakaaro ki ngā whakaritenga tono motuhake me ngā here pāmahana kia pai ai te mahi.
Hei whakamutunga, he tino iti te mimiti wai o te pepa UHMWPE, iti iho i te 0.01%. Nā tēnei āhuatanga ka ātete ki te makuku, ahakoa i roto i ngā taiao makuku, ā, ka whakaitihia te mōrearea o te pupuhi, o ngā huringa rānei o te rahi. Ka whai wāhi atu tēnei ki tōna mahi roa me te pakari.
Ka whakamahia te pereti UHMWPE kirihou ki ngā wāhi e paheke ana te haki, e tūtaki ai ngā wāhanga whakarewa, ka puta ai te waku, te pakaru rānei. He tino pai mō ngā arai o te hāpara me te hopper, ngā waka kawe, ngā wāhanga rānei, ngā papa pakaru, ngā arataki mīhini, te mata pānga me ngā arataki.
Hei whakamutunga,Rau UHMWPEKo te otinga tino pai mō ngā tono e hiahia ana kia nui te ātete ki te pakū me te pānga. Nā ōna āhuatanga maha e hiahiatia ana pērā i te ātete ki te UV, te ngāwari ki te tukatuka, te kore e taea te whakamahi i ngā matū, te iti o te waku, te kore e piri, ngā āhuatanga hiko pai, te ātete ki te makariri, me te iti o te mimiti wai, kua noho hei rauemi e pai ana ki ngā momo ahumahi. Nō reira, ahakoa kei te rapu koe i te ātete kakahu pai ake, i ngā wāhanga hangarau pono rānei, ko te pepa UHMWPE tāu whakautu!
