I roto i te hoahoa taura muka whatu (OFC), he mea nui te whiriwhiri i ngā rauemi mata tika. Ko ngā taiao mahi rerekē—pērā i te tino makariri, te pāmahana teitei, te haumākū, te tāutanga o waho, te piko tonu, te nekehanga pinepine rānei—ka whakatakoto i ngā whakaritenga rerekē mō ngā rauemi taura whatu. I konei, ka whakarāpopotohia e mātou ētahi rauemi matua e whakamahia whānuitia ana i roto i te umanga, me te tātari i ō rātou āhuatanga mahi me ngā tono mahi hei āwhina i te arotau i tō hoahoa taura muka whatu me te whiriwhiri rauemi.
1. PBT (Polybutylene Terephthalate) — Te Rauemi Tino Noa mō ngā Ngongo Wetekina
PBTKo te rauemi tino whānuitia te whakamahi mō ngā ngongo wetewete i roto i ngā taura muka whatu. Ka pakarukaru ngā kirihou taura noa i ngā pāmahana iti, ā, ka ngawari i ngā pāmahana tiketike. Ko te PBT kua whakarerekētia, hei tauira me ngā wāhanga mekameka ngāwari, ka whakapai ake i te ātete pānga pāmahana iti, ā, ka taea te whakatutuki i ngā whakaritenga tae atu ki te -40°C. Hei tāpiri, he tino pakari te PBT me te pumau o ngā āhuatanga i ngā pāmahana tiketike, e whakarite ana i te tiaki pono mō ngā muka i raro i te ahotea wera. Nā tōna mahi taurite, te utu whaitake, me te maha o ngā whakamahinga ka waiho hei whiringa noa mō ngā taura whakawhitiwhiti kōrero o waho, ngā taura tawhiti, me ngā hanganga taura ADSS.
2. PP (Polypropylene) — He pakari rawa atu i te pāmahana iti me te ātete ki te waikura
Kua arohia te PP i roto i ngā rauemi taura whatu nā tōna pakari pai ki te pāmahana iti, ā, ka ārai i te pakaru i ngā āhuatanga tino makariri. He pai ake hoki tōna ātete ki te waikura i te PBT, ā, he pai mō ngā taiao makuku, wai-nui rānei. Heoi, he iti ake te modulus me te pakari o te PP i te PBT, nō reira me whai whakaaro ki te hanganga taura motuhake. Hei tauira, ko ngā taura māmā, ko ngā taura ranu o roto-waho, ko ngā hanganga ngongo wetewete rānei e hiahia ana ki te ngāwari ake, ka taea te whiriwhiri i te PP hei huarahi kē.
3. LSZH (Low Smoke Zero Halogen) — Te Rauemi Matua mō te Koti Taura Hoa-taiao
LSZHKo te rauemi koti taura e whakamahia whānuitia ana, e hoa ana ki te taiao. Ko ngā hanganga LSZH kounga teitei, i tutukihia mā roto i ngā pūnaha polymer motuhake me ngā hangarau whakakī, ka taea te whakatutuki i ngā whakaritenga pānga pāmahana iti -40°C me te pupuri i te whakamahinga roa i te 85°C. Mēnā ka puta he ahi, ka tukuna e te LSZH he iti te paoa, ā, kāore he hau halogen, ka nui ake te haumaru mō ngā taura o roto, ngā taura pokapū raraunga, me ngā waea whare tūmatanui. He ātete pai hoki ki te pakaru o te ahotea taiao me te waikura matū, ka waiho hei whiringa maha mō ngā koti taura o roto, o waho hoki.
4. TPU (Thermoplastic Polyurethane) — Te "Kīngi" o te Ngāwari o te Pāmahana Iti me te Ātete ki te Waro
He rongonui te TPU mō tōna ngāwari me tōna pakari i raro i ngā pāmahana tino iti. Kāore i rite ki te PVC, he tino ngāwari tonu te TPU, ā, kāore e pakaru. He tino pai hoki tōna ātete ki te pakū, ki te hinu, me te haehae, he mea tino pai mō te neke taura, tae atu ki ngā taura mekameka tōia, ngā taura waka, ngā taura keri, ngā taura karetao, me ngā tono aunoatanga ahumahi. Kia mahara ko te ātete pāmahana teitei me te ātete waikura o te TPU e whakawhirinaki ana ki te momo motuhake, nō reira he mea nui te whiriwhiri i ngā whakatakotoranga kounga teitei.
5. PVC (Polyvinyl Chloride) — Kōwhiringa Utu-Pai mō te Koti Taura me ngā Herenga Pāmahana-Iti
Kei te whakamahia tonutia te PVC mō ētahi taura whatu nā te mea he iti te utu me te ngāwari o te tukatuka. Heoi, ka whakapakeke te PVC paerewa, ā, ka pakaru pea i raro i te -10°C, ka kore e pai mō ngā āhuatanga tino makariri. Ka taea e te PVC pāmahana iti, ātete makariri rānei te whakaheke i te pāmahana whakawhiti karāhe mā roto i ngā kirihou, engari ka pā kino pea tēnei ki te kaha miihini me te ātete tawhito. Nō reira, he pai ake te PVC mō ngā kaupapa utu iti i roto i ngā taiao pumau, pērā i ngā whakaurunga o roto paerewa, ngā whakaritenga taura rangitahi rānei.
6. TPV (Thermoplastic Vulcanizate) — Te Whakakotahi i te Āhua o te Rapa me te Āhua o te Tukatuka Kirihou
Ka whakakotahi a TPV i te ngāwari o te rapa me te ngāwari tukatuka o te kirihou. He tino pai te ātete ki te pāmahana teitei me te pāmahana iti, me te ātete tino pai ki te huarere me te ātete ki te ozone. Nā te ngāwari me te roa o te TPV e pai ai mō ngā taura whatu o waho, ngā waea motuka, me ngā taura ngāwari. Hei rauemi, ka whakataurite a TPV i ngā āhuatanga o te TPU me te PVC, ka whakarato i te ngāwari hanganga me te pakari taiao.
7. XLPE (Polyethylene Hononga-Whārite) — Rauemi Ārai Mahana-Teitei mō ngā Taura Whatu me ngā Taura Hiko
XLPE, mā te hononga whakawhiti, ka whakarei ake i te ātete wera, ā, ka taea te mahi tonu i runga ake i te 90°C. Ka whakarato hoki i te kaha miihini me te ātete ahotea tino pai. Ahakoa he nui ake te whakamahinga o te XLPE mō te whakamarumaru taura hiko (hei tauira, 1kV–35kV), i ētahi wā ka whakamahia i roto i ngā taura whatu mō te whakapakari, ngā tono pāmahana teitei rānei. Nā ōna āhuatanga wera me te miihini e pai ai mō ngā taura whatu motuhake i roto i ngā taiao uaua.
Te Kōwhiri i ngā Rauemi mō te Koti Taura Whatu — He Mea Matua ngā Horopaki Taupānga
Ko te whiriwhiri i ngā rauemi taura whatu tika e hiahia ana kia nui atu i te arotake noa i ngā raraunga hangarau; me whai whakaaro hoki ki ngā horopaki tono tuturu:
Tāutanga Pūmau (waho, paipa hiko, pūaha hiko): LSZH, TPV, XLPE
Ngā tono neke (mekameka tōia, karetao, waka, keri maina): TPU
Te Mātao Tino Nui (-40°C, iti iho rānei): PBT, PP, TPU kua Whakarerekētia
Taura o roto, Whakamahinga Paerewa, Kaupapa Tairongo-Utu: PVC (e taunakitia ana i raro i ngā tikanga motuhake anake)
Kāore he otinga "kotahi te rahi e pai ana mō te katoa" mō ngā rauemi taura whatu. Me ahu mai te kōwhiringa i tētahi aromatawai whānui o te hanganga taura, ngā āhuatanga tāutanga, te tahua, me te pono mō te wā roa.
