Ko te rapa nitrile butadiene (NBR) me te polyvinyl chloride (PVC) he rauemi e rua e whakamahia whānuitia ana i roto i te umanga whakamahana, inā koa i roto i ngā tono hiko me te wera. Nā ō rāua āhuatanga ahurei ka pai ai mō ngā momo taiao, engari ka rerekē te mahi a ēnei rauemi whakamahana i runga i te tukanga hanga. He mea nui te mārama ki te pānga o ngā tikanga hanga rerekē ki te mahi whakamahana o ngā rauemi NBR/PVC mō ngā kaihanga me ngā kaiwhakamahi mutunga.
Ko ngā āhuatanga whakamarumaru o ngā rauemi NBR/PVC e whakawhirinaki ana ki tōna kawe wera, te kaha dielectric, me te manawanui ki ngā āhuatanga taiao pēnei i te haumākū me ngā piki me ngā heke o te pāmahana. Ka pāngia ēnei āhuatanga e te hanganga rauemi, ngā tāpiringa, me ngā tukanga motuhake e whakamahia ana i roto i te hanga.
Ko tētahi o ngā tukanga hanga matua e pā ana ki te mahi whakamahana ko te tikanga whakakotahi. I tēnei wāhanga, ka whakaranua ngā pūmua turanga (rapa nitrile me te polyvinyl chloride) ki ngā momo tāpiringa, tae atu ki ngā mea whakapūmau kirihou, ngā mea whakau, me ngā mea whakakī. Ko te kōwhiringa o ngā tāpiringa me tō rātou kukū ka tino whakarerekē i ngā āhuatanga wera me te hiko o te hua whakamutunga. Hei tauira, mā te tāpiri i ētahi mea whakapūmau kirihou ka taea te whakapai ake i te ngāwari me te whakaiti i te kawe wera, i te mea ka taea e ngā mea whakakī motuhake te whakapai ake i te kaha miihini me te pumau wera.
Ko tētahi atu tukanga hanga matua ko te tikanga whakaputa, te tikanga whakapūkara rānei e whakamahia ana hei hanga i ngā rauemi ārai. Ko te whakaputa ko te pēhi i te ranunga o ngā rauemi mā roto i te mata hei hanga i tētahi āhua tonu, ko te whakapūkara ia ko te riringi i ngā rauemi ki roto i tētahi kōhao kua oti te hanga. Ka puta he rerekētanga i roto i te mātotoru, te ōritetanga, me te hanganga whānui o te rauemi ārai i ia tikanga. Hei tauira, ko ngā rauemi ārai NBR/PVC kua whakaputahia, tera pea he ōritetanga pai ake, he iti ake te poretanga ki ngā hua kua whakapūkarahia, ā, ka pai ake te mahi ārai.
He mea nui te mahi a te tukanga whakamaroke i roto i ngā āhuatanga whakamahana o ngā rauemi rapa nitrile/polyvinyl chloride (NBR/PVC). Ko te whakamahana, e mōhiotia ana ko te whakamomona, e pā ana ki te tukanga honohono-whiti i ngā mekameka polymer mā te whakamahi i te wera me te pēhanga, ka hua ake he rauemi pumau ake, he pakari ake hoki. Ka pā te roa me te pāmahana o te tukanga whakamahana ki ngā āhuatanga whakamutunga o te rauemi whakamahana. Ki te kore e ranea te whakamahana ka kore e oti te honohono-whiti, ka whakaiti i te ātete wera me te kaha dielectric. I tetahi atu taha, ka pakarukaru, ka ngatata te rauemi i te wā e whakamahana ana.
Hei tāpiri atu, ka pā te tere whakamatao i muri i te hanga ki te āhua tioata me te āhua o ngā rauemi NBR/PVC. Mā te whakamatao tere ka piki ake ngā hanganga kore-āhua, ka taea te whakapai ake i te ngāwari engari ka whakaiti i te pumau o te wera. I tētahi atu taha, mā te tere whakamatao puhoi ka taea te whakatairanga i te tioata, ka whakapai ake i te ātete wera engari ka iti ake te ngāwari.
I roto i te poto, he nui te pānga o ngā tukanga hanga ki ngā āhuatanga whakamahana o ngā rauemi NBR/PVC. Mai i te whakaranu me te whakakoi ki te whakamaroke me te whakamatao, ka whakarerekēhia e ia taahiraa o te tukanga whakaputa ngā āhuatanga wera me te hiko o te hua whakamutunga. Me āta whakaaro ngā kaihanga ki ēnei āhuatanga hei whakapai ake i te mahi whakamahana o ngā rauemi NBR/PVC mō ngā tono motuhake. I te mea kei te tipu haere tonu te hiahia mō ngā rauemi whakamahana mahi-teitei, he mea nui te rangahau me te whakawhanake tonu i ngā hangarau whakaputa hei whakapai ake i te mahi o ngā otinga whakamahana NBR/PVC i roto i ngā taiao rerekē.
