PU pahuka i te Rangatū Poari Waihanga
Whakaahuatanga
Ko te papa whakahiato polyurethane polyurethane maataki he papa whakamaarama me nga mea whakamaarama polyurethane polyurethane maamaa hei mea matua me te paparanga whakamarumaru sima i nga taha e rua.Ka tangohia e ia nga taputapu hanga-tuarua-tuarua, kaore i te tutuki i nga paerewa teitei o te hanga i te whakamaarama-whakaora, engari ka whakarei ake i te pumau o te punaha;he rua nga atanga o te poari ina wehe atu ia i te wheketere, ka taea te karo i te ahi i puta mai i nga reke hikareti me te whakapiri hiko i te wa o te kawe waka, te whakatuu waahi hanga me te hanga pakitara;Ko te polyurethane pahuka i te whakamaroke i te werawera, ka kore e pa ki te ahi.Te rewa, karekau he pupuhi wera, kaore he mura ahi i muri i te hanga o te punaha, ka tino pai ake te aukati ahi i te wa e whakamahia ana.Ka taea e te paparanga mata rua-taha te whakanui ake i te kaha o te hononga o te papa whakamarumaru, te whakapiri me te raima raima, na reira ka whakarite i te pono me te pumau o te punaha.

Nga ahuatanga o te mahi hua
01|Weariki whakawera
Ko te pahuka polyurethane mārō he hanganga hono-whakawhitinga, te tikanga kati-pūtau (te reiti whakatuwhera 5%), me te iti rawa o te kawe werawera, 0.021W/(mK anake).
02|Ohanga
He wa roa te whakamahi me te pai o te mahi whakawera waiariki.Ko tona matotoru he 2/3 te angiangi atu i te slurry waiariki me te 1/3 te angiangi atu i te papa polystyrene.He pai rawa atu te mahinga utu whanui mo ia waahanga tapawha.
03|pumau
Ko te pahuka polyurethane te nuinga o te tango i te polyether polyether-free-halogen-free flame-retardant polyol, me te taapiri i te ūkuikui-i runga i te mura o te ahi me te whai hua whakakotahi ki te whakatutuki i te hanganga mura-kore-halogen i roto i nga ngota ngota me te kore e piki ake te nui o te isocyanate.Kua tae te mahi mura-muri ki te paerewa B1;kua paahitia e te polyurethane te punaha whakamatao pakitara o waho i nga kaupapa maha me nga whakaaturanga maha-pūnaha, a karekau he ahuatanga o te takahanga o nga mea whakamatao i muri i te tono miihini.
04|Tiaki Taiao
Ma te whakamahi i te hangarau hukahuka kore-fluorine me nga hua kore-aldehyde, no nga rawa whare kaakaariki.
05|Te mauroa
He pai te aukati matū, ka taea te whakamahi mo te wa roa i te pāmahana -180°C ~150C.He tino pai te parenga huarere me te whakatio-rewa ka taea te whakamahi mo te 50 tau.
06|Hanga
He maamaa, he haumaru, he pono hoki te mahi hangahanga, ka taea te kowhiri i nga momo hangahanga mo nga kaupapa rereke.
