He maha ngā kaihoko e pātai ana i te pātai kotahi i te wā e whiriwhiri ana i ngā wira: ko tēhea te mea pai ake, ngā wira polyurethane, ngā wira rapa rānei?
Kāore he whakautu kotahi mō tēnei pātai. He painga anō ō ngā rauemi e rua, ehara ko wai te mea "tino matatau", engari ko wai te mea e tika ana mō te taiao whakamahinga tūturu. I te wā e whiriwhiri ana, me arotahi ki ngā whakaritenga amo kawenga, ngā āhuatanga o te whenua, te auau o te whakamahinga, ngā whakaritenga haruru, me te tahua.
Ki te kī ngāwari, mēnā he nui te kawenga o te taputapu, he maha ngā whakamahinga, he roa te tawhiti pana, he uaua rānei ngā āhuatanga mahi pērā i ngā paru hinu me ngā matū i te papaanga, he pai ake ngā wira polyurethane; mēnā he nui ake te aro ki te mimiti ru, te whakaiti haruru, me te tiaki whenua, ā, kāore i te nui te kawenga o te taputapu, he pai ake te whiriwhiri i ngā wira rapa.
1. Ngā āhuatanga matua o ngā wira polyurethane
Ka whakakotahi ngā wira polyurethane i te kaha ki te pikau kawenga, te ātete ki te kakahu, me te mama o te nekeneke, ka waiho hei momo wira noa i roto i te mahi ahumahi me te whare putunga.
Tuatahi, he tino ātete ngā wira polyurethane ki te pakaru, ā, he roa ake te mau i ngā wira rapa noa i roto i te whakamahinga auau teitei, te pana tawhiti, me ngā taiao whenua taratara. Ina koa i ngā wāhi kei reira te wai, te hinu, te matū rānei i runga i te whenua, ka kitea tōna pumau.
Tuarua, he pakari pai ngā wira polyurethane, ā, kāore e ngāwari te whakapēhanga i te pēhanga, he pai ake mō te whakamahi i ngā taputapu taumaha me ngā taputapu reo-rahi. I taua wā anō, he iti te ātete hurihuri, he māmā ake te pana, ā, he pai mō ngā waka kawe taonga, ngā kaata taputapu, ngā taputapu rokiroki, me ētahi taputapu aunoa.
Hei tāpiritanga, ko ngā wira polyurethane he iti ake te tūponotanga ki te waiho i ngā tohu pango ki te whenua, ā, he pai ake mō ngā wāhi he nui ngā whakaritenga mō te horoi pēnei i ngā papa rakau, ngā papa epoxy, ngā hōhipera, me ngā awheawhe kai.
Heoi anō, he ngoikoretanga anō hoki ō ngā wira polyurethane. Nā te mea he pakari te rauemi, kāore i te rite te pai o tana mimiti ru me tana mahi ārai ki ngā wira rapa. Ina tūtaki ki te whenua kāore i te ōrite, he iti noa iho tōna kaha ki te mimiti i ngā wiri; i ētahi taiao, tera pea ka paku teitei ake te haruru mahi. Hei tāpiri, he nui ake ngā utu rauemi me te hanga i ngā utu o ngā wira rapa, nō reira he nui ake te utu.
2. Ngā āhuatanga matua o ngā wira rapa
Ko te painga o ngā wira rapa nui kei roto i tōna ngāwari pai, tōna pānga mimiti ru mārama, me te ngāwari ake o te whakamahinga.
I te wā e kawe ana i ngā taputapu tika, ngā taputapu hiko, ngā hua karāhe, me ētahi atu taonga e pāngia ana e te wiri, ka taea e ngā wira rapa te ārai pai ake i ngā pānga o te whenua me te whakaiti i te pānga o ngā tukinga. I taua wā anō, he ngawari ake tōna pā ki te whenua, ā, he pai ake te wheako kaiwhakamahi i roto i ngā taiao pēnei i ngā wāhanga hōhipera, ngā tari, me ngā whare pukapuka e hiahia ana kia nui te whakahaere haruru.
Hei tāpiritanga, he pai ake te mahi ā-kore paheke o ngā wira rapa, ā, he kaha ake te pupuri i ngā mata haukū, maeneene rānei. Hei tāpiritanga, me ngā tukanga whakaputa kua pakeke me ngā rauemi mata noa, he pai ngā painga utu o ngā wira rapa i roto i ngā tono mama maha.
Heoi, mō te ātete ki te kakahu me te kaha ki te pikau i ngā kawenga, kāore i te rite te pai o ngā wira rapa ki ngā wira polyurethane. Ina roa te wā e pāngia ana e ngā kawenga taumaha, e te whakamahinga auau teitei, e te whenua taratara rānei, ka ngāwari ake te kakahu me te whakarerekē i ngā wira rapa nā te nui rawa o te pēhanga, ā, ka pā tēnei ki te roa o te wā e whakamahia ana.
Hei tāpiritanga, he nui ake te ātete hurihuri o ngā wira rapa, ā, he uaua ake te pana; ka waiho pea ētahi wira rapa pango i ngā tohu ki te whenua. Mēnā ka roa te wā e pāngia ana e te ultraviolet, te ozone, te hinu rānei, ka ngāwari ake te koroheketanga, te pakaru, me ētahi atu raruraru o ngā rauemi rapa.
3. Me pēhea te whiriwhiri i waenga i ngā wira polyurethane me ngā wira rapa
Mena he mea whakamahi tō taputapu mō ngā mahi taumaha, me neke haere rānei i ia rā, he pai ake te whakamahi i ngā wira polyurethane. He ātete ki te kakahu, he kaha ake te kawe kawenga, ā, he māmā ake te whakamahi. I te nuinga, he pai ake mō ngā taputapu ahumahi, ngā waka whakawhiti mahi, ngā waka putunga me te whakahaere, me ētahi atu āhuatanga.
Mena he paru hinu, he kai horoi, he matū rānei, he nui rānei ngā whakaritenga mō te horoi o te whenua i runga i te papa, he pai ake te whakamahi i ngā wira polyurethane.
Mena ko te arotahi ki te mimiti ru, te whakaiti haruru, me te tiaki utanga, he pai ake te whakaaro ki ngā wira rapa. Hei tauira, i roto i te kawe i ngā taputapu tika, ngā taputapu hauora, ngā taputapu whakaatu, me ētahi atu, he nui ake ngā painga o ngā wira rapa ki te ārai me te whakaiti haruru.
Mena kāore i te nui te kawenga taputapu, he toharite te auau whakamahi, ā, he iti noa te tahua, he pai te whakamahi i ngā wira rapa hei kōwhiringa utu iti.
4. He mea pai kia arotahi ki ēnei āhuatanga ina whiriwhiri ana i ngā tauira tuturu
Tirohia te kaha o te kawenga. Ka taumaha ake te taputapu, ka teitei ake ngā whakaritenga mō te ātete ki te pikau kawenga me te ātete ki te hurihanga o ngā wira.
Tuarua, tirohia te whenua. Ko ngā whakamātautau whenua taratara he nui ake te ātete ki te pakaru, ko te whenua maeneene ia he nui ake te aro ki te marino, te ātete ki te paheke, me te tiaki i te whenua.
Tuatoru, tirohia te taiao. Ahakoa e pā ana ki te hinu, ki te wai, ki ngā matū rānei, ahakoa e whakamahia ana i waho mō te wā roa, e whakamahia pinepine ana rānei, ka pā katoa ēnei ki te kōwhiringa rauemi.
Tuawhā, tirohia te whāinga whakamahinga. Ahakoa he ātete ki te kakahu me te penapena mahi, he marino ake rānei, he mimiti ake i te ru, he rerekē te kaupapa matua e pā ana ki ngā whāinga rerekē.
Tuarima, tirohia te tahua. Mō ngā taputapu roa, auau-rahi, me te mahi-taumaha, he mea nui ake te whiriwhiri i ngā rauemi e tika ana i te whakaiti noa i ngā utu hoko.
Whakarāpopototanga
Kāore he rerekētanga tino whānui i waenga i ngā wira polyurethane me ngā wira rapa, ko te mea anake e mōhiotia ana ko te pai mō ngā āhuatanga mahi o nāianei.
He pai ake ngā wira polyurethane mō ngā mahi taumaha, te ātete ki te kakahu, te taraiwa tawhiti, me te whakamahinga taiao uaua; he pai ake ngā wira rapa mō ngā āhuatanga e hiahia ana kia mimiti te ru, kia whakaiti i te haruru, kia ātete ki te paheke, me te whakahaere utu.
I roto i ngā mahi hokohoko tūturu, me whakatau whānui i runga i te taumaha o ngā taputapu, te auau o te whakamahinga, te āhua o te whenua, me te tahua. Mā te whiriwhiri i ngā rauemi tika ka pai ake te wheako o te kaiwhakamahi, ka whakaitihia hoki ngā utu tiaki me te whakakapinga i ngā wāhanga o muri mai.
