Ko ngā āhuatanga o te mowhiti hiri polyurethane he ātete ki te kakahu, te hinu, te waikawa me te kawakore, te ozone, te koroheketanga, te pāmahana iti, te haehae, te pānga, me ētahi atu. He nui te kaha tautoko kawenga o te mowhiti hiri polyurethane, ā, he whānuitia te whakamahinga i roto i ngā mara maha. Hei tāpiri, he ātete te mowhiti hiri whakarewa ki te hinu, ki te waikura, ki te kakahu, ā, he kaha teitei, e tika ana mō ngā taputapu hinu pēhanga teitei, ngā taputapu hiki, ngā taputapu mīhini hanga, ngā taputapu waipēhi nui, me ētahi atu.
Mowhiti hiri polyurethane: he tino pai ngā āhuatanga miihini o te polyurethane, ā, he pai ake tōna ātete ki te kakahu me te pēhanga teitei i ētahi atu rapa. He tino pai hoki tōna ātete ki te koroheketanga, ki te ātete ki te ozone me te ātete ki te hinu, engari he ngāwari ki te waikura i te pāmahana teitei. He mea whakamahi whānuitia mō ngā hononga hiri ātete ki te pēhanga teitei me te ātete ki te kakahu, pērā i ngā rango waipēhi. Ko te whānuitanga pāmahana he – 45~90 ℃.
Haunga te whakatutuki i ngā whakaritenga whānui mō ngā rauemi mowhiti hiri, me aro hoki ngā mowhiti hiri polyurethane ki ngā āhuatanga e whai ake nei:
(1) Ki tonu i te ngāwari me te manawanui;
(2) Te kaha ā-ringa e tika ana, tae atu ki te kaha whakawhanui, te roa me te ātete haehae.
(3) He pumau te mahi, he uaua ki te pupuhi i roto i te reo, ā, he iti te pānga whakaheke wera (pānga Joule).
(4) He māmā te tukatuka me te hanga, ā, ka taea te pupuri i te rahi tika.
(5) Kāore e waikura te mata pa, kāore hoki e poke i te rauemi.
Ko te arotahi a Ningbo Yokey Automotive Parts Co., Ltd ki te whakaoti rapanga rauemi rapa a ngā kiritaki me te hoahoa i ngā whakatakotoranga rauemi rerekē i runga i ngā ahuatanga tono rerekē.
