Paewhiri Hanawiti Polyurethane

Hei rauemi whakamarumaru whare e penapena ana i te kaha, kua noho te panera hanawiti polyurethane hei wāhanga nui o ngā whare ahumahi hou, ngā whare putunga ratonga, me ngā whare rokiroki makariri. Ko tēnei momo panera whare, e whakakotahi ana i ngā paparanga mata whakarewa me te rauemi polyurethane, e matapaetia ana ka nui haere te hiranga a meake nei.

Mahi Tino Pai
Ko te painga matua o te panera hanawiti polyurethane kei roto i tōna mahi whakamahana tino pai. He pai ngā āhuatanga whakamahana o ngā rauemi pahuka polyurethane, me te kawe wera iti iho i te 0.017-0.025 W/(m·K). Ko te tikanga o tēnei ka taea e te panera he 5 henimita te matotoru te whakatutuki i te pānga whakamahana rite ki te pakitara raima kotahi mita te matotoru. Nā tōna mahi whakamahana tino pai, kua noho ngā panera hanawiti polyurethane hei rauemi pai mō te hanga whare rokiroki makariri.

Ko te ārai wai, te ātete makuku, me te pumau teitei ētahi atu painga o ngā panera hanawiti polyurethane. Neke atu i te 95% te tere pūtau-kati o te matua pahuka polyurethane, e ārai ana i te urunga makuku. Ko te tere mimiti wai o ngā panera hanawiti polyurethane he iti iho i te 3%. I taua wā anō, i raro i ngā rerekētanga pāmahana o te 30°C, he iti iho i te 1% te huringa āhua o ngā panera, e whakarite ana i te whakamahinga roa me te kore e whakarerekē.

Ka taea e ngā panera hanawiti polyurethane te ātete ahi ki te Akomanga B1. He mura ngā panera hanawiti polyurethane, engari ka mutu te mura i roto i te 3 hēkona i muri i te tangohia mai i te mura. Ahakoa he iti iho te kaha o te mura i ngā panera hanawiti wūru toka i tēnei āhuatanga, ka tutuki tonu i a rātou ngā whakaritenga haumaru ahi taketake.

I runga i te hanganga, nā ngā paparanga e rua o ngā panera whakarewa i te tihi me te raro, he kaha te hanganga o ngā panera hanawiti polyurethane. Ko te kaha pēhi o ngā panera hanawiti polyurethane he nui ake i te 150 kPa. Heoi, ko te rauemi matua ko te pahuka polyurethane, e 30-60% te mama ake o ngā panera i ngā hua tuku iho. Nā tēnei ka waiho ngā panera hanawiti polyurethane hei rauemi pai mō te hanganga mama.

Te Hiahia Whakaputa Nui
I tēnei wā, he tino aunoa te tukanga whakaputa o ngā panera hanawiti polyurethane. Ko ngā kaihanga matua, pērā i a Harbin Dong'an Building Sheets Co., Ltd., e whakamahi ana i ngā raina whakaputa tonu hei whakauru i te tukanga katoa o te pahuka, te whakamaroke, me te hanga i ngā panera.

Ko te whakapūpū me te hanga i te pehanga teitei he taahiraa matua i roto i te hanga o ngā panera hanawiti polyurethane. Ko te kounga o te whakapūpū te mea e whakatau tika ana i te mahi a ngā panera. I te wā e hanga ana, me whakahaere tika e ngā kaihanga te pāmahana o te papa mekameka me ngā rauemi whakapūpū. He mea nui anō hoki te tere o te raina whakaputa, nā te mea ka pā ki te ōritetanga o te tukanga whakapūpū matua.
