Ko te paninga parewai Polyurethane he ahua o te prepolymer kei roto Isocyanate kua rite ma te taapiri polymerization o Isocyanate, polyether me etahi atu, me te whakakorikori, te taapiri anhydrous, te kaihoko whakakī anhydrous, te whakarewa, me etahi atu, kotahi-waahanga polyurethane paninga parewai i hangaia ma te whakaranu me etahi atu nga tukanga.Ko tenei ahua o te paninga he tauhohenga-whakaoranga (moisture-curing) paninga ki te kaha nui, elongation tiketike, pai te ātete wai me te pera i runga i.He kaha te urutau ki te paheketanga o nga pakiaka tarutaru.Polyurethane paninga parewai ko te ahua o te kotahi-wahanga tiaki taiao paninga parewai tono i roto i te āhua wai.Kei runga i te polyurethane prepolymer kawemai kaore he ta me te uku.Ko te makuku i roto i te rangi i muri i te rongoa whakapā, i roto i te mata o te turanga ki te hanga i te apa o te kaha, me te uaua tuitui anti-kiriata.
āhuatanga hua
(1) ka taea te tono tika ki runga i nga momo papanga makuku maroke ranei.
(2) ki te adhesion kaha ki te mata turanga, kiriata i roto i te rauemi polymer e taea te kuhu ki te mata turanga moroiti-kapiti, kaha whai-ake.
(3) he pai te ngawari o te kiriata, he pai te urutau ki te roha turanga, ka pakaru ranei, me te kaha o te kaha.
(4) tiaki taiao, kore-paitini reka, kore-pollute taiao, kahore he kino ki te tangata.
(5) te pai o te rangi, te teitei o te pāmahana kaore e rere, te iti o te pāmahana e kore e pakaru, te pai o te mahi anti-hoholo, te aukati hinu, te mau kakahu, te atete ki te ozone, te waikawa me te waikawa alkali.
(6) he kiato te kiriata paninga, kua oti te paparanga parewai, kahore he kapiti, kahore he Pinhole, kahore he mirumiru, a he iti te whakareatanga kohu wai.(7) he ngawari te hanga, he poto te waa hanga, he watea te tiaki (8) kia rite ki te hiahia, ka taea te tuku i ia tae (9) he maamaa te kounga, kaore e nui ake te utaina o te whare..
