Kupenga UHMWPEKo te kupenga polyethylene taumaha ngota tino teitei, he rauemi mata i hangaia mai i te polyethylene taumaha ngota tino teitei (UHMWPE) mā te tukanga raranga motuhake. Ko tōna taumaha ngota i te nuinga o te wā kei waenga i te 1 miriona ki te 5 miriona, he nui ake i te polyethylene noa (PE), e homai ana ki a ia ngā āhuatanga ā-tinana me ngā āhuatanga ā-pūkaha ahurei.
I te tīmatanga, i rongonuihia mō tōna mahi tino pai i roto i ngā tono porotiti me te tiaki, kua āta whakamahia te kupenga UHMWPE ki ngā hua mata. Ko te rahi o te mata oKupenga UHMWPE ka taea te whakarite (mai i te maikorona ki te henimita) ā, e wātea ana i roto i ngā tae mā, mangu, mārama rānei. Kei roto i ētahi hua ngā hihi UV me ngā matū ārai-pakeketanga hei whakarite kia pai mō ngā taiao o waho.
Neke atu i te 10 ngā wā o tōna kaha kume i te maitai he ōrite te taumaha, ā, tata ki te 40% teitei ake i te muka aramid (Kevlar). Heoi, ko tōna matotoru he 0.93-0.96 karamu/cm anake.³, he iti iho i te konganuku me te nuinga o ngā muka mahi-teitei. Nō reira, i te mea he tino pai te tiakitanga, ka tino whakaitihia te taumaha katoa, ka māmā ake te tāutanga me te whakahaere.
Ko tōna mata maeneene me te hanganga mekameka ngota pumau e whakarato ana i te ātete tino pai ki te kakahu me te ātete pānga e rima ngā wā i te polyethylene noa. Ka taea e ia te tu atu i te waku me te pānga maha me te kore e whati, ā, ko tōna roa mahi he nui ake i te kupenga nairona, polyester rānei tuku iho.
He tino ātete ki te waikura ki ngā waikawa, ki ngā kawakore, ki ngā tote, me ngā whakarewa rauropi. Ka ātete ki te koroheketanga me te pirau i roto i ngā taiao makuku, nui te tote (pēnei i ngā taiao moana) me ngā taiao poke ahumahi, ā, he pai mō te whānuitanga o ngā tono.
Ahakoa i roto i ngā pāmahana tino iti tae atu ki te -196°C, ka mau tonu te ngāwari me te ātete pānga, ka whakakore i te mōrearea o te pakarukaru. Ka mahi pūmau hoki i roto i ngā taiao pāmahana teitei (i raro i te 80°C). Ko te mea i hangaia motuhakeKupenga UHMWPE ka taea te whakarei ake mā te whakamahi i ngā whakau UV hei pupuri i te mahi pumau ahakoa i raro i te rā tika mō te wā roa, hei whakaroa i te koroheketanga me te whakaroa i tōna roanga mahi o waho.
Kāore te rauemi tonu i te paitini, kāore hoki he kino, ā, ka taea te hangarua (ētahi tauira) i muri i te maka atu, kia iti ai te pānga ki te taiao. Kāore hoki e mimiti, e ātete ana ki te harore, ā, he ngāwari ki te tipu o ngā huakita, kia pai ai te whakamahi i roto i ngā taiao e pā ana ki te kai me ngā hua wai.
Mā te whakamahi i tōna kaha teitei me te ātete ki te pakū, ka whakamahia i roto i ngā kupenga hī ika me ngā kupenga putea. Ka taea e ia te tu atu i ngā pānga mai i ngā mea ora o te moana me te waikura mai i te wai moana, ka whakapai ake i te whai huatanga o te hī ika me te whakapai ake i te roanga o te ora o ngā kupenga. Ngā Kete Whakatipu Ika: Ka whakamahia i roto i ngā mahi whakatupu ika moana hohonu, wai māori rānei, ka tiaki i te hau me ngā ngaru, i ngā kaipahua (pērā i ngā mango me ngā manu moana), ā, ka whakarite i te rere o te wai me te kore e pā ki te tipu o ngā mea ora o te wai.
Kupenga ārai hinga/kupenga haumaru: Whakamahia hei kupenga haumaru i te wā hanga me ngā mahi rererangi, hei ārai rānei i te hinganga o ngā toka i roto i ngā piriti, ngā kauhanga, me ētahi atu kaupapa.
Kupenga tiaki kararehe mohoao: Ka whakamahia i roto i ngā whare kararehe me ngā rahui taiao, hei wehe i ngā kararehe me te ārai i te kino.
Ki te whakaritea ki ngā kupenga polyethylene noa, he ātete ake ēnei ki ngā patunga a ngā manu, ki te hau me te ua, ā, he pai mō te tiakitanga mō te wā roa i roto i ngā māra hua rākau, i ngā whare kati kōtuhi, me ētahi atu wāhi.
Hei tautoko piki mō ngā waina (pērā i te karepe me te kiwi), he kaha te kawe kawenga, ā, he ātete hoki ki te koroheketanga.
Pērā i ngā taiapa o te papa korowha me ngā kupenga wehe o te kooti tēnehi, ka taea e rātou te tu atu i te pānga o ngā pōro tere-nui, ā, ka noho ātete tonu ki te whakarerekētanga.
Pērā i ngā kupenga piki me ngā kupenga haumaru mahi rererangi, he māmā te hoahoa, he māmā hoki te kawe me te tāuta. Ngā Whakamahinga Ahumahi me ngā Whakamahinga Motuhake
Mā te ātete ki te waikura me te mata tino tika, e whakamahia ana mō te tātari i ngā wai, i ngā totoka rānei i roto i ngā ahumahi matū me te keri.
Hei ārai tiaki rangitahi, ka whakakotahihia e rātou te ātete huna me te ātete pānga.
Kupenga UHMWPE, me ōna painga o te kaha teitei, te mama, me te ātete ki te taiao, kei te whakakapi haere i ngā rauemi tuku iho pēnei i te mata whakarewa me te mata nairona, ā, ka noho hei whiringa mahi teitei i roto i ngā momo tono, inā koa i roto i ngā tono he tino kaha ngā whakaritenga mahi rauemi.
