I roto i ngā āhuatanga pēnei i te hanga miihini, te huihuinga taputapu, me te whakahaere taonga, he rite tonu ngā wira ki ngā wāhanga iti, engari he pānga tika ki te ngāwari o te nekehanga, te pumau o ngā taputapu, me te marino o te papa. Ko te take e whakamahia pinepine ai ngā wira polyurethane (PU) whānui i roto i ngā taputapu ahumahi me ngā kaata, he mea ka taea e rātou te whakatutuki i te mahi taurite i waenga i te "kaha kawe kawenga, te ātete kakahu, me te mimiti ru wahangu". Kei raro nei, ka whakamāramahia e mātou tōna mātāpono mahi i roto i te huarahi māmā ake mai i ngā tirohanga rauemi me te hanganga, me te tuku whakaaro kōwhiringa.
1. He aha te take e whakamahia whānuitia ai te polyurethane (PU) i roto i ngā wira ahumahi?
Ko ngā painga o te mata o te wira polyurethane e ahu mai ana i ngā āhuatanga e rua: ko te kaha me te ngāwari o te rauemi i te wā kotahi.
Āhua ngāwari: Ina pāngia e te kaha, ka rerekē te āhua, ka marara te pēhanga pa, ka whakaiti i te tūponotanga o te kino ā-rohe ki te mata o te wira.
Kaha rawa: Ki te whakaritea ki te rapa noa, he ātete ake te PU kounga teitei ki te kakahu me te haehae, he pai mō te hurihuri auau teitei me te hurihanga auau.
Te hurihuri maeneene: I te nuinga o ngā mata papatahi, he iti ake te ātete hurihuri o ngā wira PU, ā, he māmā ake te pana.
He ātete pai ki te koroheketanga me ngā pāpāho: I roto i ngā taiao ahumahi pēnei i ngā paru hinu me te haumākū, kāore te PU me ngā hanganga e tika ana e ngāwari te whakangawari, te pakaru rānei (e taunakitia tonutia ana kia whakaūhia kia rite ki te pāpāho tuturu).
2. He aha i mārie ake ai ngā wira PU whānui? Nā te pānga whakakotahi o te "rauemi+hanganga" te nuinga
Ehara i te mea ko te "ngawari" anake te kaupapa o te whakangā, engari ko te whakahaere i te pānga me te wiri me te kore e pā ki te kaha ki te pikau kawenga.
Ka mimiti te rauemi i te wiri: He ngāwari te PU, ā, ina whiti ngā wira i roto i ngā hononga whenua, i ngā paepae iti rānei, ka mimitihia te pānga e te mata o te wira, ā, he iti ake te haruru i te nuinga o te wā i te haruru o ngā wira nairona me te maitai.
He pumau ake te pānga: He pumau ake te pānga i waenga i te mata o te wira me te whenua, ā, he iti ake te tūponotanga kia rangona he oro "pakaru".
Te ōrite o te rahi me te whānui o te wira: Ina nui ake te whānui o te wira, ā, he pai ake te whānui o te wira, ka maeneene ake te hurihuri, ā, ka iti ake te haruru.
3. He aha ngā take ka taea ai e ngā wira PU whānui te pikau i te taumaha? Kei te "uho wira, te whānui o te wira, te whāriki, me te peera"
Ko te kaha o te wira ki te kawe i te kawenga ehara i te mea ko te rauemi anake o te mata o te wira e whakatauhia ana, engari ko te hanganga katoa. Arotahi ki:
Hanganga matua wira: e whakamahia whānuitia ana hei matua nairona, matua konumohe, matua rino rānei. Ko te matua wira te tautoko matua, e whakatau ana mēnā ka ngāwari te whakapē i raro i ngā kawenga taumaha.
Te whānui me te whānui o te wira: Ko te whānui o te wira, ko te iti o te pēhanga o te waeine, ā, ko te pumau ake; he nui ake te rahi o te wira, ā, he pai ake mō te whiti i ngā kapiti whenua me ngā arai iti.
Whirihoranga o te peera: He mea nui ake ngā peera pono me te pai o te taunga miihini mō ngā kawenga taumaha, ki te kore ka ngāwari te pakarukaru haere i te whakamahinga. He mea pai kia whiriwhiria ngā peera hiri mō ngā taiao puehu, wai rānei.
Te kaha o te whāriki me te hanganga o te tēpu hurihuri: Ko te āheinga o te wira whānui ki te hurihuri maeneene i raro i ngā kawenga taumaha e pā tata ana ki te pīrere tēpu hurihuri, te matotoru o te pereti maitai, me te kounga o te whakapūmau/whakapiri.
4. Te uara o te hanganga whānui: he aha i taea ai te huri i te 360°?
Kei roto i te wira whānui he wira me te tēpu hurihuri ka taea te hurihuri. Ka hurihia e te tēpu hurihuri te whāriki huri noa i te ahunga poutū mā roto i te hanganga whāriki, kia taea ai e te taputapu te whakarerekē tere i te ahunga ina panaia, he pai mō ngā teihana mahi me ngā kāreti he whaiti ngā awaawa, he maha ngā hurihanga, me ngā hiahia hurihanga auau.
5. Ngā āhuatanga tono noa (ko ēhea taputapu e pai ake ana mō te whakamahi i ngā wira PU whānui)
Te nekehanga me te tiaki i ngā taputapu: ngā taputapu taputapu mīhini, ngā tēpu taputapu, me ngā turanga taputapu nekeneke (e hiahia ana kia pumau te kawe kawenga me te whakahaere maeneene).
Ngā kāreti kawe me ngā kāreti hurihanga: te whakahaere auau teitei, ngā huarahi roa (he nui ake te aro ki te ātete ki te kakahu me te penapena mahi).
Ko ngā raina aunoa me ngā raina whakaputa e hiahia ana kia ngāwari te urungi, kia iti ake hoki te pānga o te haruru ki te papa mahi (me te aro nui ki te pumau me te iti o te haruru).
6. Whakaaro whiriwhiri: Tirohia ēnei mōhiohio e whitu, ā, kāore pea koe e hē te whiriwhiri.
1). Te kaha kawenga: Taumaha taputapu + kawenga nui ÷ te maha o ngā wira, me te 20% -30% te toenga kawenga hihiri e rahuitia ana (me whakamārama motuhake te āhuatanga o te kawenga kore taurite).
2). Whenua: epoxy/taera uku/sima/pereti maitai/uku uku; He paepae, he pakaru whenua, he paru, he arawhata rānei.
3). Auautanga whakamahinga: auau/tawhiti whakatairanga o ia rā; Ahakoa he maha ngā tahuritanga, he hiahia rānei ki te whakarerekē i te ahunga i te wāhi.
4). Te whānui me te whānui o te wira: E taunakihia ana kia nui ake te whānui o te wira i te mea ka kino haere te whenua; Me whānui ake te mata o te wira mō te taumaha rawa.
5). Ngā matua wira me ngā whāriki: Mō ngā kawenga taumaha, he mea pai kia whiriwhiria ngā matua wira kaha ake me ngā whāriki pono ake; Me matua hoatu te hiri i ngā whāriki i roto i ngā taiao puehu/horoi.
6). Te pūmau me te pērai: E taunakihia ana kia whakamahia ngā pērai takirua (raka hurihuri +raka urungi) hei whakanoho; Kia aro ki te matotoru o te pūmau me te hanganga o te tēpu hurihuri.
7). Ngā pāpāho taiao me te pāmahana: Me whakaū te hanganga rauemi me te taumata ārai-waikura i ngā paru hinu, ngā kai horoi, te ngoikore o te waikawa me te kawakore, ngā taiao makariri me te wera, me ētahi atu.
Whakamutunga
Ko te take e whakamahia whānuitia ai ngā wira polyurethane whānui i roto i te umanga mīhini, he mea ka taea e rātou te whakataurite i te ātete ki te kakahu, te penapena mahi, te mimiti ru, me te pumau o te pikaunga. Engari i te wā e whiriwhiri ana, kaua e titiro noa ki te "ingoa rauemi" me te "tau pikaunga" rānei, engari whakaarohia hoki te kaha pikaunga, te whenua, te taiao, me te hanganga pikaunga/tautoko. Whakamāramahia ngā āhuatanga mahi, kātahi ka whakataurite i te whānui o te wira, te whānui o te wira, te hanganga matua o te wira, me te whirihoranga parai. Ka tino pumau ake te roa o te ora me te wheako kaiwhakamahi o ngā wira.
