Ngā Painga o te Whakakī Pahuka Polyurethane
1. He tino whai hua, he penapena pūngao hoki, kāore he āputa i muri i te whakakī, ā, he kaha te hononga i muri i te whakamaroke.
2. He ātete ki ngā ru, ā, he kaha ki te pēhi, ā, e kore e pakaru, e waikura, e taka rānei i muri i te whakamaroke.
3. He iti rawa te kawe wera o te pāmahana, he ātete ki te huarere me te tiaki wera.
4. He tino pai te ārai i te haruru, he ātete wai, he ātete makuku hoki i muri i te whakamaroke.
He aha ngā mea me aro atu ki te wā hanga?
Ko te pāmahana whakamahinga noa o te pahuka polyurethane ko +5~+40℃, ā, ko te pāmahana whakamahinga pai ko +18~+25℃. Mēnā he iti te pāmahana, me whakanoho ki te pāmahana pumau mai i te +25 ki te +30 °C mō te 30 meneti i mua i te whakamahinga kia pai ai te mahi. Ko te awhe ātete pāmahana o te pahuka kua whakamarokehia ko -35℃～+80℃.
He pahuka whakaora-makuku te pahuka polyurethane, ā, me rehu ki ngā mata mākū ina whakamahia. Ka tere ake te whakamakuku o te pahuka, ka taea te horoi i te pahuka kāore anō kia whakamakuku ki ngā kai horoi, engari ka tangohia te pahuka whakaora mā ngā tikanga ā-ringa (te kirikiri, te tapahi rānei). Ka huri te pahuka whakaora ki te kōwhai ina pāngia e te hihi ultraviolet. E taunakihia ana kia pania te mata o te pahuka whakaora ki ētahi atu rauemi (te moata sima, te peita, me ētahi atu). I muri i te whakamahinga o te pū rehu, horoia tonutia ki te kai horoi motuhake. Ina whakakapia te tāke rauemi, rūrūtia te tāke hou kia pai (kia 20 ngā wā), tangohia te tāke kau, ka tere te whakakapi i te tāke rauemi hou kia kore ai e whakamakuku te hononga pū.
Mā te takirere whakahaere rere me te keu o te pū rehu e whakahaere te nui o te rere o te pahuka. Katia te takirere rere ki te taha matau ina mutu te rehu.
