Mēnā kei te whakamahi mātou i ngā mīhini he turanga ara rino, hei tiaki i te mata o te rori me te pupuri tonu i te kaha o ngā ara rino ki te kawe i ngā kawenga, ko te tikanga ka whiriwhiri mātou ki te tāuta i ngā hū rapa, i ngā papa rapa rānei ki runga i ngā ara. I ēnei rā, ka whiriwhiria e mātou i runga i te rauemi o ngā papa rapa anake.
I tēnei wā, ko ngā rauemi o ngā papa rapa e whakamahia ana mō ngā turanga ara i te mākete ko te rapa me te polyurethane. Nō reira, ko te kaupapa matua o te whiriwhiri i waenga i ēnei e rua he tino māmā: i roto i ngā āhuatanga mahi uaua, ko te polyurethane te mea e whai ana mātou kia roa te ora o te mahi, ā, ko te polyurethane te mea e pai ake ana ki a mātou; i runga i ngā whenua pahekeheke mō ngā mahi, me kaha te kukume, kātahi ka whiriwhiria te rapa i te tuatahi.
※ Mena kei te rapu koe i te roa o te ora mahi me te ātete kaha ki te kakahu: whiriwhiria te polyurethane (PU)
· Ko te ātete kakahu o te polyurethane he 3 ki te 10 ngā wā i tō te rapa, ā, ko tōna roa mahi he 2 ki te 3 ngā wā i tō te rapa.
· He ātete ki te haehae me te tapahi, he kaha te pupuri i te taumaha, ā, e rua ngā wā e kaha ake ana i te rapa. He pai mō ngā mīhini mira rori me ngā taputapu keri i roto i ngā āhuatanga mahi taumaha.
· He ātete ki te hinu me te waikura, kāore e tawhito, e ngatata rānei, ā, he whānui ake te awhe pāmahana mahi (-30°C ki te 80°C).
※Mena he pahekeheke te taiao mahi, he mea rānei e hiahiatia ana he parenga ki te papa rori: whiriwhiria te rapa
· He ngawari ake te kakano, ā, ka kaha ake te pupuri i ngā pari mākū, i ngā pari wai rānei.
· He pai ake tōna ngāwari, ā, ka taea e ia te mimiti i ngā ru hei tiaki i te pūnaha anga.
· He iti ake te kino o te papa rori, ā, he pai hoki mō ngā kaihanga papa e mahi ana i runga i ngā mata rori uku, sima, pereki rānei.
※Ngā whakaaro mō te utu
· Te utu hoko tuatahi: He iti ake te utu o te rapa i te polyurethane i te 25%.
· Te utu whakamahinga whānui: Ahakoa he nui ake te haumitanga tuatahi o te polyurethane (30% - 50%), ka taea e tōna roa rawa te mahi te whakaiti i te auau o te whakakapinga me te wā kore mahi, ā, i te wā roa, tera pea he nui ake te whai huatanga o te utu.
Anei tētahi kōwhiringa hei tango i te ara poto: Ka taea e koe te aromatawai i te taiao mahi o te taputapu i te tuatahi.
· Mō ngā āhuatanga mahi uaua pērā i ngā maina, ngā kauhanga, ngā pari, ngā mīhini taumaha rānei, ko te polyurethane (PU) te mea pai rawa atu.
· Mō ngā taputapu e tika ana kia tū ki ngā mata pahekeheke pērā i ngā rori mākū, i ngā pari pari rānei, mō ngā mīhini whakahaere papa uku pērā i ngā papa whakarewa, ko te rapa te kōwhiringa pai.
Hei whakarāpopototanga, mā te whakatau mēnā ko te roa o te ora (te whiriwhiri i te polyurethane) te pupuri rānei (te whiriwhiri i te rapa), me te whakaaro ki te kōwhiringa rauemi o ngā wāhanga katoa o te anga katoa, ka kitea e koe te otinga e tino tika ana mō ō hiahia whakahaere!
