He pumau te mahi a te pahuka, he māmā, he whakamarie, ā, he ma ake te mahi a ngā rauemi.

I te mea kei te piki haere tonu te hiahia o te ao mō ngā rauemi pahuka māmā, pakari, me te roa, kei te arotakehia anō ngā pūnaha EVA (ethylene-vinyl acetate) tuku iho mō ō rātou herenga mahi mō te wā roa. Ko ngā wero noa—pērā i te whakaiti i te pūmautanga, te whakahekenga wera, te whakarerekētanga o te pēhanga, me te hekenga tāpiri—ka pā ki te ōritetanga o te hua, te roa, me te wheako kaiwhakamahi puta noa i ngā hu, ngā hākinakina, me ngā tono ahumahi.

I runga i tēnei horopaki,Si-TPV 2250-75A, he elastomer thermoplastic e ahu mai ana i te silicone i whakawhanakehia mō te whakarerekētanga pahuka EVA, kei te tūhuratia hei huarahi rauemi rerekē. I hangaia me te wāhanga silicone kua whakamomonahia kia marara i roto i te matrix thermoplastic, ka whakauruhia e te rauemi he ara rerekē mō te aro ki ngā here hanganga me te tukatuka i roto i ngā pūnaha pahuka EVA.

Te Whakaaro Anō i ngā Wero o te Hanga Pahu EVA

Ko te hanga pahuka EVA he tikanga he taunekeneke matatini i waenga i ngā matū pupuhi, ngā tauhohenga hononga whakawhiti, me te rheology rewa. Ko ngā rerekētanga o ngā matapihi pāmahana me te taurite hanganga ka arahi pea ki te āhua pūtau koretake, te kore pumau o ngā āhuatanga, me ngā huringa o te mahi miihini. Hei tāpiri, ko ngā whakarerekētanga tuku iho—pērā i te SEBS, ngā kirihou, ngā tāpiringa hinu rānei—ka whai wāhi pea ki ngā take roa tae atu ki te piri o te mata, te hekenga, me te heke haere o te mahi.

Kua whakanohohia te Si-TPV 2250-75A hei rauemi e taunekeneke ana ki tēnei pūnaha i roto i ngā momo rerekē. Ko tōna hanganga iti, he mea hanga mai i ngā rohe rapa silicone kua marara pai (tata ki te 1–3 μm), ka mahi pea hei wāhi whakapūtanga rerekē i te wā e pupuhi ana. E hono ana tēnei āhuatanga hanganga ki te hanganga o ngā tohatoha pūtau ōrite ake me te pai ake o te ōritetanga o te pupuhi i raro i ngā tikanga tukatuka whakahaeretia.

Te Āhua o te Huka me te Whēkau Ahu

He mea nui te ōritetanga o te hanganga pahuka ki te whakatau i te pumau ā-pūkaha me te kounga o te mata. Ko te whakaurunga o te Si-TPV 2250-75A ki roto i ngā hanganga EVA kua honoa ki ngā hanganga pūtau pai ake me ngā āhuatanga o te mata maeneene ake.
