Ko te whakapiko i ngā kōtaha PVC (pērā i ngā anga tatau me ngā matapihi, ngā whakapaipai, me ētahi atu) i te wā whakaputa, rokiroki, tāutanga, whakamahinga rānei e pā ana ki te whānui me te whakaheke wera, te ātete ngoki, ngā kaha o waho, me ngā rerekētanga o te pāmahana me te haumākū o te taiao. Me whakatinana ngā mahi puta noa i te tukanga katoa—mai i te whakahaere whakaputa, te rokiroki me te kawe, te tāutanga me te hanga, ki te tiaki auau - ka taea te whakarōpū ki ngā wāhanga matua e whā e whai ake nei:
Wāhanga Whakaputa: Te Arotau i ngā Tukanga hei Whakapai ake i te Ātete ā-roto o te Kōtaha ki te Piko
Ko te kounga ā-roto oNgā kōtaha PVCkoinei te tūāpapa mō te ārai i te piko. Me whakarei ake ngā whakatikatika whakaputa i te pumau o te hanganga mā te:
1. Te arotau i ngā ōwehenga rauemi mata hei whakanui ake i te pakari me te ātete ki te ngoki
- Mō ngā rauemi matua, kia tika te whakahaere i te ōwehenga o te kapia PVC, ngā mea whakau, me ngā mea whakakirihou. Whakauruhia ngā whakakī me ngā whakarerekētanga pānga kia rawaka ai te modulus piko o te kōtaha i te pāmahana rūma ≥2500MPa.
- Āta karohia te whakamahi nui rawa i ngā rauemi hangarua, nā te mea ka iti haere te parakore me te nui haere o ngā poke ka hua ake ngā āhuatanga ā-pūkaha kāore i te ōrite, ka tūpono ai ngā wāhanga ki te piko ā-rohe.
2. Arotauhia ngā tukanga whakaputa me te whakamatao hei whakaiti i ngā ahotea o roto
- I te wā e whakaputa ana i te tīwiri, whakahaeretia te tere o te tīwiri me te pāmahana o te whakaputanga hei ārai i te rewa kore taurite i puta mai i te wera nui, te pēhanga nui rānei o te whakaputanga mai i te koretake o te pāmahana, ka puta ai ngā ahotea o roto ka piko.
- I te wā e whakamatao ana, e whakatakoto ana, whakamahia te 'whakamatao whakarara' hei whakarite kia noho tonu te rerekētanga pāmahana i waenga i te roto me te waho o te kōtaha ki te ≤5°C. Mā tēnei ka ārai i te tere whakamatao kāore i te ōrite, ka puta ai te whakahekenga wāhanga kāore i te ōrite, ka arahi pea ki te piko ki te taha angiangi o te pakitara. Me tino ōrite te mate whakatakoto ki te whakawhiti o te kōtaha hei ārai i te whakarerekētanga i te wā e whakaputa ana.
Te Rokiroki me te Kawe: Ārai i te Pēhanga o Waho me ngā Huringa Ohorere o te Pāmahana/Makuku o te Taiao
Ngā kōtaha PVCka ngāwari te piko wawe nā te ahotea, nā ngā āhuatanga taiao rānei mēnā ka rongoatia, ka haria rānei i waenga i te tukunga mai i te wheketere me te tāutanga. Ko ngā whakaaro matua ko:
1. Te whakarārangi paerewa: Āta karohia te 'pēhanga nui, te whakatakotoranga whakarara, te pānga tika rānei o te rā'
- Me papatahi, me maroke hoki ngā wāhi whakarārangi; kaua e waiho ki waho. Mena e tika ana kia waiho hei wāhi rokiroki rangitahi ki waho, taupokina ki te ārai rā me ngā tāpaera ārai ua hei ārai i te wera o roto.
- Me whakarārangi whakapae ngā kōtaha kia paparanga; kāore e whakaaetia te whakarārangi poutū, te matotoru rawa rānei.
- Wehea ngā kōtaha o ngā roa me ngā wāhanga whakawhiti rerekē; karohia te whakamahi i ngā kōtaha wāhanga-whaiti hei tautoko mō ngā mea whānui.
2. Te Tiakitanga o te Kawe: Whakaitihia te Wiri me te Pānga
- Whakapūmautia ngā kōtaha i te wā e kawe ana mā te whakamahi i ngā whata motuhake, i ngā pito takai rānei ki te takai mirumiru. Āraia te whakarārangi i ētahi atu taonga taumaha ki roto i te waka ka taea te pēhi i ngā kōtaha. Me whakarite kia hauhautanga i te wā e kawe ana i tawhiti; kia mau tonu te pāmahana o te kāpini i raro i te 40°C i te wā e tukuna ana i te raumati.
- Whakamahia te 'hikinga pito-rua' i te wā e utaina ana/e wete ana. Ko ngā kōtaha e neke atu ana i te 6m te roa me whakamahi i te forklift me ngā āpiti hiki motuhake hei whakarite i te tohatoha kaha taurite.
Te Tāutanga me te Hanganga: Te Whakatikatika Tika hei Whakakore i te Taumahatanga Tāutanga
He mea nui te tāutanga hei ārai i teKōtaha PVC(ina koa ko te piko o te kōtaha matapihi/tatau). Āraia te whakarerekētanga roa e puta mai ana i te ahotea nā te rerekētanga o te tāutanga:
1. Tirotiro i mua i te tāutanga: Tīpakohia ngā kōtaha whai mana, ā, tukua kia taunga ki te taiao
- Tirohia ia kōtaha i mua i te tāutanga: Manatokohia te tika mā te whakamahi i te taha tika me te peka e whakaaetia ana he ≤2mm/m. Whakakahoretia, ā, āraia te whakamahi i ngā kōtaha e nui ake ana i te manawanui. Tirohia ngā mata mō ngā karawarawa, ngā pakaru rānei.
- Whai muri i te tukunga ki te wāhi tāutanga, tukua ngā kōtaha kia 'whakamahia mō ngā hāora 24' i mua i te tāutanga. Mā tēnei ka taea te urutau ki te pāmahana me te haumākū o te taiao, ka ārai i ngā huringa āhuahanga nā te whānui/whakaiti wera, te mimiti makuku rānei i puta mai i ngā nekehanga ohorere mai i ngā āhuatanga makariri/maroke ki te wera/haumākū, ka taea ai te piko i muri i te tāutanga e te ahotea.
2. Tāutanga Paerewa: Me whakarite kia 'mau te pumau me te tohatoha kawenga taurite'
- I te wā e tāuta ana i ngā kōtaha tatau me ngā matapihi, tohua ngā rārangi tohutoro mō te tūnga. Me tutuki te mokowā o ngā pūwāhi whakapiri ki ngā whakaritenga. Me rite ngā whakapiri ki ngā rara whakakaha o te kōtaha, ina nui ake te matotoru o te pakitara, ā, ina kaha ake te kaha ki te pikau kawenga. Kāore e whakaaetia te whakapiri ki ngā wāhanga angiangi.
- Mō ngā kōtaha whānui, tāutahia ngā tautoko waenga i ngā wā ≤1.5m hei ārai i te piko nā te whānui, te taumaha-ake, ngā kaha o waho rānei.
- Āta karohia te 'tāutanga ā-pūmau': Mēnā he nui rawa ngā āputa i waenganui i ngā kōtaha me ngā pakitara/ētahi atu wāhanga, whakakīia ki te hiri pahuka polyurethane. Kāore e whakaaetia te patu ki te hama, te pēhi ā-pūmau rānei i ngā kōtaha.
Te Whakamahinga me te Tiaki i ia Rā: Te Whakaiti i te Kino o Waho me te Pirau o te Taiao
Whai muri i te tāutanga, mā te whakahaere hē i te wā e whakamahia ana i ia rā, mā te tawhito rānei o te taiao ka pāngia peaNgā kōtaha PVCkia piko. Kia mahara ki ēnei e whai ake nei:
1. Āraia te ahotea ā-rohe, te pānga roa rānei
- I te wā e whakamahi ana i ngā tatau me ngā matapihi, kaua e okioki ki aua tatau mō te wā roa, kaua hoki e whakairi i ngā mea taumaha ki runga i ngā kōtaha. Āraia ngā kawenga kukū mō te wā roa ka puta he āhua rerekē o te ngoki. Whakatuwheratia, ka kati mārire ngā tatau/matapihi, me te karo i ngā pānga kaha ki ngā taha o te anga.
- Me tirotirohia auau ngā kōtaha PVC o waho mō ngā paru kua kohia, ā, me tango wawe tonu ēnei.
2. Te tiaki auau hei whakaroa i te koroheketanga
- Horoia ngā kōtaha PVC o waho i ia 1-2 tau, kia tino maroke i muri mai. Mēnā ka memeha, ka ngatata rānei te mata, pania he paninga tiaki PVC motuhake.
- I te makariri o te takurua, ka pakarukaru ake ngā kōtaha PVC; karohia ngā pānga kaha. I te werawera o te raumati, kaua e horoia tika ngā kōtaha ki te wai matao.
Ko te kaupapa matua mō te ārai i te piko o te kōtaha PVC he rua ngā wāhanga: te whakapakari i te ātete ā-roto o ngā rauemi ki te piko, me te whakaiti i ngā pānga kino mai i ngā kaha o waho me ngā āhuatanga taiao puta noa i te rokiroki, te tāutanga, me te whakamahinga. Me mahi tahi tēnei puta noa i ngā wāhanga maha: te whakahaere i ngā tukanga whakaputa me ngā rauemi mata i te pito hanga; te ārai i te kuru me te piki me te heke o te pāmahana/haumākū i te wā rokiroki me te kawe; te whakarite kia tika te whakatika me te tohatoha ahotea taurite i te wā tāutanga; me te whakaiti i te kino me te koroheketanga i te wā e whakamahia ana i ia rā. Mā tēnei huarahi maha-āhua anake ka taea te karo i te piko o te kōtaha PVC, kia roa ake ai tōna ora mahi.
