I roto i ngā mahi hanga ahumahi hou, te hanga whakarewa, te huihuinga motuka, me te tukatuka karāhe taumaha, ko ngā whara ringa kei roto tonu i ngā tūponotanga mahi e tino kitea ana, e tino utu nui ana hoki. Mō ngā tekau tau, i whakawhirinaki ngā kaiwhakahaere haumaru ki te hiako taumaha, ki ngā ranunga miro matotoru, ki ngā aramid hangai o te whakatupuranga o mua rānei hei whakarato i te tiaki taketake mai i ngā taha koi, ngā kohao whakarewa, me ngā mīhini kutikuti. Ahakoa i tukuna e ēnei rauemi he turanga parepare, i whakaatuhia e rātou he taupatupatu nui i roto i te taumaha, te rahi tinana, me te pūkenga ā-ringa.
I ēnei rā, kei te hurihia te umanga taputapu tiaki whaiaro (PPE) e te panonitanga hanganga. Ko te whānui o te whakamahinga o te muka Ultra-High Molecular Weight Polyethylene (UHMWPE) kei te huri i ngā paerewa tiaki ringa ahumahi. Mā te whakakotahi i te kaha kume tino nui me te taumaha iti, ka taea e te muka UHMWPE ngā kaihanga karapu te whakaputa i te PPE māmā, ngāwari e tutuki ai te ātete tapahi pai rawa atu me te kore e whakararu i te whakamarie o te kaimau, te mana whakahaere motuka rānei.
E tūhuratia ana e tēnei tātari hangarau te pūtaiao rauemi kei muri i te muka UHMWPE, me pēhea e tautuhia ai e ia ngā paerewa ātete-tapahi o te ao, me te take i noho ai hei rauemi whiriwhiri mō ngā karapu haumaru taumata-tiketike.
Te Mahere Irahiko: He aha te mea e ātete ai te muka UHMWPE ki te tapahi?
Hei mārama he aha te ātete tapahi teitei o te muka UHMWPE, me tirotiro tātou i tōna hanganga ngota. He rerekē ki te polyethylene tikanga, he hononga polymer peka, he mekameka poto, ko te UHMWPE he mekameka ethylene kua whakapūhuitia, he tino roa, kāore he peka. Ko te papatipu ngota o ēnei mekameka ngota kei waenga i te 3.5 me te 7.5 miriona waeine papatipu ngota.
I roto i te tukanga hanga miro motuhake, ka whakarārangihia ēnei mekameka polymer nunui i te tuaka roa o te muka. Mā tēnei taumata teitei o te whakatakotoranga me te tioata ka hangaia he whakatakotoranga whakarara pai, ka taea ai te tohatoha ōrite i te ahotea ā-tinana o waho puta noa i te hanganga ngota katoa. I runga i te taumaha-mō-te-taimaha, mā tēnei whakatakotoranga ngota ka kaha ake te muka UHMWPE ki te 15 ngā wā i te maitai hanganga, ā, he nui ake te ātete ki te pakaru me te pānga i ngā muka aramid paerewa.
Ngā Tikanga o te Mōrearea Tapahi:Ina pā te mata koi, te mata whakarewa rānei ki te karapu i whatuhia mai i te muka UHMWPE, ka ārai te kaha kume roa teitei i te mata ki te hopu me te tapahi i roto i ngā miro takitahi. Engari, mā te mata pahekeheke, iti te waku o te polymer ka taea e te mata koi te reti i te raranga, ka marara te kaha miihini puta noa i te mata whānui, kaua ki te arotahi ki te pūwāhi kotahi o te rahunga.
Te Whakahou i ngā Paerewa o te Ao: Ngā Kōtaha Mahi ANSI me EN388
Ka aromatawaihia e te rāngai haumaru ahumahi te mahi karapu i runga i ngā pūnaha whakamātautau matua e rua o te ao: te paerewa ANSI/ISEA 105 o Amerika Te Raki me te anga EN 388 o Ūropi. Ka inehia e ngā paerewa e rua te nui o te kaha e hiahiatia ana e te mata miihini hei tapahi i te papanga tauira i raro i ngā āhuatanga whakahaeretia.
I ngā wā o mua, ko te whakatutuki i ngā whakatauranga teitei (pēnei i te ANSI Cut Level A4 ki te A6, ngā EN388 Levels D me E rānei) me whai paparanga matotoru, matotoru o te papanga whatu, he maha ngā wā ka whakapakarihia ki te muka karāhe pakarukaru, ki ngā matua maitai taumaha rānei. He maha ngā wā ka whakapataritari i te kiri ēnei hanganga hiato, ka ngenge hoki te ringa, ka ārahi i ngā kaimahi ki te tango i ā rātou karapu, ka whakanui ake i te tūponotanga o te whara.
Kua hurihia tēnei tauira e te muka UHMWPE. Mā te whakamahi i ngā miro UHMWPE whakahāngai-teitei, ka taea e ngā kaihanga te whakatutuki i ngā whakatauranga tapahi ANSI teitei me ngā whatu paparanga-kotahi, ine-teitei (pērā i ngā anga 15-ine, 18-ine rānei). Ka puta mai i tēnei ētahi painga mahi matua:
Te Tairongo Paa Whakarei Ake:Ka taea e ngā kaimahi te whakamahi i ngā here iti, i ngā hikohiko moroiti, me ngā taputapu tino tika me te kore e tangohia ō rātou karapu haumaru.
Te ngenge o te ringa o raro:Mā te ngāwari o te UHMWPE ka taea e te karapu te hangai ki te hanganga o te ringa, ka whakaiti i te ātete i ngā nekehanga hopu auau.
Te Whakamarie Wera Whakapai Ake:He nui te kawe wera o te UHMWPE, e āhei ai te tere o te memeha o te wera o te ringa. Mā tēnei ka noho mātao ake ngā ringa, ka noho whakamarie ake hoki i ngā wā roa o te mahi, ki te whakaritea ki ngā mea hangai e pupuri ana i te wera.

Te Roa o te Mahi me te Whai Hua o te Utu
Haunga ngā painga haumaru tonu, e pai ana ngā kaiwhakahaere haumaru ahumahi ki te muka UHMWPE mō tōna whai huatanga utu mō te wā roa. I roto i ngā taiao ahumahi taumaha, ka pāngia ngā karapu mahi e ngā hinu, ngā hinu whakangao, ngā whakarewa, me ngā huringa horoi pinepine.
He maha ngā karapu aramid ka pirau ina pāngia e te makuku me ngā hopi horoi ahumahi, ka ngaro te ōrau o ō rātou āhuatanga ātete-tapa i ia huringa horoi. He rerekē, he koretake te muka UHMWPE i ngā matū, ā, he tino ātete-wai. Kāore e mimiti i te wai, i te hinu, i ngā otinga horoi matū rānei. Ka taea te horoi i ngā karapu i hangaia mai i te muka UHMWPE kounga teitei i ngā wā katoa me te kore e mimiti, e ngaro te kaha kume, e whakararu rānei i ō rātou whakatauranga tapahi ANSI/EN388. Mā tēnei roanga o te oranga mahi ka whakaitihia te auau o ngā whakakapinga, ka whakaitihia te utu hoko PPE whānui mō ngā umanga ahumahi nui.
