Ko ngā pūnaha hiko o ēnei rā e whakawhirinaki ana ki ngā hononga i waenga i ngā taputapu rerekē, ngā papa hiko, me ngā taputapu tāpiri. Ahakoa te tuku hiko, te tuku tohu hiko rānei, ko ngā taura te pou tuarā o ngā hononga waea, ā, he wāhanga nui ēnei o ngā pūnaha katoa.
Heoi, he maha ngā wā ka whakaitihia te hiranga o ngā koti taura (te paparanga o waho e karapoti ana, e tiaki ana hoki i ngā ara iahiko o roto). He whakatau nui te whiriwhiri i te rauemi tika o te koti taura i roto i te hoahoa me te hanga taura, inā koa ka whakamahia i roto i ngā taiao uaua. Ko te mārama ki te taurite i waenga i te mahi miihini, te ātete taiao, te ngāwari, te utu, me te tutuki i ngā ture te mea nui ki te whakatau whakaaro nui.
Kei te ngākau o te koti taura he whakangungu rakau hei tiaki, hei whakarite hoki i te roa me te pono o te taura o roto. Ka tiakina e tēnei parenga mai i te makuku, ngā matū, ngā hihi UV, me ngā ahotea ā-tinana pērā i te pakaru me te pānga.
Ko ngā rauemi mō ngā koti taura mai i ngā kirihou māmā ki ngā pūmua matatau, he āhuatanga ahurei tō ia mea hei whakatutuki i ngā whakaritenga taiao me ngā whakaritenga miihini. He mea nui te tukanga whiriwhiri nā te mea ko te rauemi tika ka whakarite i te mahi tino pai me te tiaki i raro i ngā tikanga whakamahinga e tumanakohia ana.
Kāore he otinga "kotahi te rahi e pai ana mō te katoa" mō ngā koti taura. Ka rerekē pea te rauemi i whiriwhiria i runga i ngā āhuatanga motuhake o te tono.
He maha ngā āhuatanga hei whakaaroaro māu i te wā e whiriwhiri ana i te rauemi tika mō te koti taura.
1. Ngā Āhuatanga Taiao
He mea nui te ātete matū i te wā e whiriwhiri ana i ngā uhi taura, nā te mea ka tūtaki pea ngā taura ki ngā hinu, ki ngā whakarewa, ki ngā waikawa, ki ngā turanga rānei, i runga i tā rātou whakamahinga. Ka taea e te uhi taura kua whiriwhiria pai te ārai i te pirau, te waikura rānei o ōna wāhanga o raro, ā, ka mau tonu te kounga o te taura i roto i tōna roanga mahi. Hei tauira, i roto i ngā taiao ahumahi e kitea whānuitia ana te pānga o ngā matū, he mea nui kia whiriwhiria ngā rauemi ka taea te tu atu ki ēnei āhuatanga kino. I konei, me aromatawai ngā matū motuhake ka pāngia te taura, nā te mea ka whakatau i te hiahia mō ngā rauemi motuhake pēnei i ngā fluoropolymers kia eke ki te ātete matū tino nui.
Ko te ātete ki te huarere me te rā tētahi atu whakaaro nui, inā koa mō ngā taura e whakamahia ana i waho. Ka taea e te roa o te pānga ki te rā te ngoikore o ngā rauemi tuku iho, ka pakarukaru, ka pakaru hoki. Mā ngā rauemi i hangaia hei ātete i te hihi UV ka noho tonu te taura me te pakari ahakoa te kaha o te rā. Mō ēnei tono, ko ngā rauemi tino pai ko ngā kirihou wera CPE, ngā whakamahana CPE, ngā whakamahana EPR rānei. Ko ētahi atu rauemi matatau, pērā i te polyethylene hono-whiti (XLPE), kua whakawhanakehia hei whakarato i te ātete UV whakarei ake, kia roa ai te ora o te taura i ngā mahi o waho.
Hei tāpiritanga, i ngā taiao e āwangawanga ana mō te mōrearea o te ahi, ko te whiriwhiri i tētahi koti taura he ātete mura, he tineia-ā-ia-anō rānei, he kōwhiringa whakaora ora pea. Kua hangaia ēnei rauemi hei aukati i te horapa o te mura, hei tāpiri i tētahi paparanga nui o te haumaru i roto i ngā tono nui. Mō te ātete mura, ko ngā kōwhiringa pai koPVCngā kirihou wera me ngā kirihou wera CPE. Ka taea e ēnei rauemi te whakaroa i te horapa o te mura me te whakaiti i te tukunga o ngā hau paitini i te wā e tahuna ana.
2. Ngā Āhuatanga Mīhini
Ko te ātete ki te pakū, te kaha pānga, me te kaha kuru o te koti taura ka pā tika ki te roa o te polyurethane. He mea nui tēnei i roto i ngā tono e whiti ana te taura i ngā whenua uaua, e hiahia ana rānei kia maha te whakahaere. I roto i ngā tono tino nekeneke, pērā i roto i te karetao, i ngā mīhini hihiri rānei, mā te whiriwhiri i tētahi koti taura he pai ake ōna āhuatanga miihini ka āwhina i te karo i te whakakapinga me te tiaki pinepine. Ko ngā rauemi pai rawa atu mō ngā uhi koti ko ngā kirihou polyurethane me ngā kirihou CPE.
3. Ngā Whakaaroaro mō te Pāmahana
Ko te awhe pāmahana whakahaere o te rauemi koti taura te mea hei rerekētanga i waenga i te angitu, te kore rānei mō tētahi pūnaha. Ko ngā rauemi kāore e taea te tu atu i te awhe pāmahana whakahaere o tō rātou taiao e hiahiatia ana, ka pakarukaru pea i ngā āhuatanga makariri, ka pirau rānei ina pāngia e ngā pāmahana teitei. Ka taea e tēnei pirau te whakararu i te kounga o te taura, ka puta ai te korenga o te whakamarumaru hiko, ka hua ake he whakararuraru mahi, he tūponotanga haumaru rānei.
Ahakoa he maha ngā taura paerewa ka taea te whakatauranga mō te pāmahana tae atu ki te 105°C, me tū atu pea ngā tono PVC motuhake ki ngā pāmahana teitei ake. Mō ngā ahumahi pēnei i te hinu me te hau, me whakamahi rauemi ngā tono motuhake, pēnei i ngā rauemi raupapa SJS a ITT Cannon, ka taea te tū atu ki ngā pāmahana tae atu ki te 200°C. Mō ēnei pāmahana teitei, me whai whakaaro pea ki ngā momo rauemi, tae atu ki te PVC i te taha thermoplastic me te CPE, EPR rānei, CPR rānei i te taha thermostat. Ka taea e ngā rauemi ka taea te mahi i roto i ēnei taiao te tū atu ki ngā pāmahana teitei me te ātete i te koroheketanga wera, kia pai ai te mahi a te taura i roto i te wā.
Whakaarohia ngā taiao pāmahana teitei, pērā i ngā taputapu keri i uta. I roto i ēnei taiao pēhanga teitei, pāmahana teitei, me whiriwhiri he rauemi uhi taura ka taea te tu atu i ngā pāmahana tino nui me te kore e pirau, e hē rānei. Hei whakamutunga, mā te whiriwhiri i te rauemi uhi taura tika ka taea te whakarite kia haumaru, kia pono hoki ngā mahi, me te whakaroa i te roa o te ora o ngā taputapu.
4. Te Hiahia mō te Ngāwari
Ko ētahi tono e hiahia ana kia noho ngāwari tonu ngā taura i raro i ngā nekehanga piko me te takahuri. Kāore tēnei hiahia mō te ngāwari e whakaiti i te hiahia mō te pakari; nō reira, me āta whiriwhiri ngā rauemi kia taurite ai ēnei whakaritenga e rua. I ēnei wā, ko ngā rauemi pēnei i te elastomers thermoplastic (TPE) te polyurethane rānei (PUR) e pai ana mō tō rātou ngāwari me te manawanui.
Hei tauira, me tino ngāwari ngā taura e whakamahia ana i roto i te aunoatanga ahumahi kia taea ai te nekeneke o ngā mīhini pēnei i ngā karetao. Ko ngā karetao mata e whakamahia ana mō ngā mahi pēnei i te kohi me te whakatakoto i ngā wāhanga he tauira pai o tēnei hiahia. Mā te hoahoa e taea ai te whānuitanga o te nekehanga, e whakanoho ana i te taumahatanga tonu ki runga i ngā taura, e hiahiatia ana te whakamahi i ngā rauemi ka taea te tu atu ki te piko me te takai me te kore e whakararu i te mahi.
Whai muri i te whakaaro ki ngā āhuatanga taiao, ngā āhuatanga miihini, te pāmahana, me ngā hiahia ngāwari, he mea nui hoki kia mōhio ka rerekē te diameter o waho o te taura i ia rauemi. Kia noho pai ai te taiao, me noho tonu te diameter o te taura ki roto i ngā rohe hiri o te anga o muri, o te hononga rānei.
