He mea nui te whiriwhiri i ngā rauemi tika hei whakarite i te pumau me te mahi roa o ngā taura whatu. He rerekē te whanonga o ngā rauemi rerekē i raro i ngā āhuatanga taiao tino kino — ka pakarukaru pea ngā rauemi noa, ka ngatata i ngā pāmahana iti, engari i ngā pāmahana tiketike ka ngohengohe, ka piro rānei.
Kei raro nei ētahi rauemi e whakamahia whānuitia ana i roto i te hoahoa taura whatu, he rerekē ngā painga o ia rauemi, me ngā tono e tika ana.
1. PBT (Polybutylene Terephthalate)
Ko te PBT te rauemi e whakamahia whānuitia ana mō ngā ngongo taura whatu.
Mā te whakarerekētanga — pērā i te tāpiri i ngā wāhanga mekameka ngāwari — ka tino whakapaitia tōna pakarukaru i te pāmahana iti, kia ngāwari ai te tutuki i te whakaritenga -40 °C.
Ka mau tonu hoki tōna pakari me te pumau o ngā āhuatanga ahakoa ngā pāmahana tiketike.
Ngā Painga: te mahi taurite, te whai huatanga o te utu, me te whānuitanga o te whakamahinga.
2. PP (Poroporoperene)
He tino pakari te PP i te pāmahana iti, ā, ka ārai i te pakaru ahakoa i roto i ngā taiao tino makariri.
He pai ake hoki te ātete ki te waikura i te PBT. Heoi, he iti ake te modulus, ā, he ngoikore ake te pakari.
Ko te kōwhiringa i waenga i te PBT me te PP e whakawhirinaki ana ki te hoahoa hanganga me ngā hiahia mahi o te taura.
3. LSZH (Paowa Kore-Harogen Pūhui)
Ko te LSZH tētahi o ngā rauemi pūtu rongonui e whakamahia ana i ēnei rā.
Mā ngā whakatakotoranga pūmua matatau me ngā tāpiringa mahi tahi, ka taea e ngā pūhui LSZH kounga teitei te tutuki i te whakamātautau pānga pāmahana iti -40 °C me te whakarite kia pumau mō te wā roa i te 85 °C.
He tino ātete ki te mura (he iti te paoa e puta ana, kāore hoki he hau halogen i te wā e tahuna ana), ā, he kaha anō hoki te ātete ki te pakaru ahotea me te waikura matū.
He kōwhiringa pai tēnei mō ngā taura ātete ahi, ā, he hoa hoki ki te taiao.
4. TPU (Polyurethane Thermoplastic)
E mōhiotia ana ko te "kīngi o te ātete makariri me te kakahu," ka noho ngāwari tonu te rauemi hipoki TPU ahakoa i ngā pāmahana tino iti, me te ātete pai ki te karawarawa, te hinu, me te haehae.
He mea tino pai mō ngā taura mekameka tōia, ngā taura keri maina, me ngā taura motuka e hiahia ana kia nekehia pinepine, me tu atu rānei ki ngā taiao makariri rawa.
Heoi, me aro nui ki te ātete ki te pāmahana teitei me te waikura, ā, me whakamahi i ngā momo kounga teitei.
5. PVC (Polyvinyl Chloride)
He kōwhiringa ōhanga te PVC mō ngā hipoki taura whatu.
Ka whakapakeke, ka pakarukaru hoki te PVC paerewa i raro i te -10 °C, ā, kāore e pai mō ngā āhuatanga pāmahana tino iti.
Ka whakapai ake ngā hanganga PVC ātete-mātao, ātete-pāmahana rānei i te ngāwari mā te tāpiri i te nui o ngā mea whakakoi kirihou, engari ka taea e tēnei te whakaiti i te kaha ā-ringa me te ātete ki te koroheketanga.
Ka taea te whakaaro ki te PVC ina he mea nui te whai huatanga o te utu, ā, kāore i te nui ngā whakaritenga mō te pono mō te wā roa.
Whakarāpopototanga
He rerekē ngā painga o ia o ēnei rauemi taura whatu i runga i te whakamahinga.
I te wā e hoahoa ana, e hanga ana rānei i ngā taura, he mea nui kia whai whakaaro ki ngā āhuatanga taiao, ki te mahi miihini, me ngā whakaritenga roa o te whakamahinga hei whiriwhiri i te rauemi tino tika.
