He whānuitia te whakamahinga o te panera Puf i roto i ngā mahi hanga, i ngā whare rokiroki makariri, i ngā whare ahumahi, me ngā hanganga modular, nā te mea he teitei te mahi whakamahana me te tere o te tāutanga. Ahakoa e whakanuia ana e ngā kaihoahoa me ngā kaihanga whare ā rātou mahi, he rerekē ngā utu i runga i ngā āhuatanga maha ka taea te ine.
Te Matotoru o te Paewhiri me te Mahi Ārai
E pā ana te matotoru o te matua o te panera hanawiti PU ki tōna utu. Ko te matotoru paerewa kei waenga i te 40 mm ki te 250 mm, ā, ko ngā panera matotoru ake ka whakarato i te whakamarumaru wera pai ake (he iti ake te uara-U) engari me nui ake ngā rauemi mata.
Ko te utu mō te panera Puf 100 mm he 20–30% te nui ake i te 50 mm te rahi, nā te mea kua nui ake te rōrahi pahuka polyurethane me te uara-R kua pai ake, ka taea te whakaiti i ngā kawenga whakamahana me te whakamatao puta noa i te huringa ora o te whare.
Ka pā te pai o te wera ki te utu nā te mea ko te whakatutuki i te kawe wera iti (tata ki te 0.022 W/m·K mō te PU) me whai hanganga pahuka tika me te whakahaere kounga.
Rauemi Matua me te Matotoru
Ko te polyurethane tonu tētahi o ngā tino take utu. He pai rawa te whakamarumaru o te hanganga pūmau o te pahuka PU ki ērā atu momo rauemi pēnei i te EPS (polystyrene whānui), engari ko ōna rauemi mata—ngā polyol me ngā isocyanate—he matū matū e rerekē ana ngā utu. E whakaatu ana ngā raraunga ahumahi ko ngā utu rauemi mata he 60–70% o ngā whakapaunga hanga panera katoa.
Hei tāpiri, ka pā te matotoru o te pahuka ki te mahi me te utu. Ka pai ake te kaha ā-ringa o te PU matotoru ake, ka iti ake te koroheketanga wera, engari ka piki ake te utu nā te nui ake o te whakamahinga rauemi me te uaua o te tukatuka. Ko te utu o te panera Puf me te matotoru matua teitei ake he 15–25% te nui ake i ngā putanga matotoru iti ake.
Ngā Rauemi Mata
Ko ngā panera hanawiti he matua PU e honoa ana i waenganui i ngā mata whakarewa e rua. Ka taea ēnei te hanga i te maitai piauau, te maitai kua peitahia, te konumohe rānei. Ko ētahi kaihanga matua, pērā i a Harbin Dongan Building Sheets Company, e whakarato ana i te panera puf me ngā panera mata Al-Mg-Mn, ka taea ai e tēnei te hanga i te panera hanawiti kia māmā ake, kia ātete ki te waikura, kia kaha ake hoki.
Ko te maitai pīataata taketake te rauemi mata tino iti te utu, ā, he ātete ki te waikura, ko te maitai kua oti te peita me te paninga PVDF, polyester rānei ka tāpiri i te pakari me te ataahua. Heoi anō, ka piki ake te utu hanga. He māmā ake ngā mata konumohe, ā, he ātete ki te waikura, engari he nui ake te utu i te maitai.
He mea nui anō hoki te matotoru o ngā kiri whakarewa. I te nuinga o te wā, ko te matotoru o te kiri maitai he 0.4-0.6 mm. Ka taea e te Kamupene Dongan te whakarato i ngā panera me ngā kiri whakarewa he 0.8mm te matotoru. Mā te kiri matotoru ka pai ake te pakari o te panera puf me te mahi kawe kawenga, ko te tikanga hoki he utu nui ake.
Ngā Whakatauranga Ahi me ngā Paerewa Haumaru
He maha ngā wā ka eke te panera Puf Paerewa ki ngā whakatauranga ahi ngawari pērā i te akomanga Euro E. Heoi, ko ngā kaupapa, pērā i ngā whare tūmatanui, ngā kura, ngā hōhipera, e hiahia ana ki ngā taumata haumaru teitei ake. Ko ngā panera e tutuki ana i te mahi ahi teitei e hiahia ana ki ngā hanganga ārai ahi motuhake, ki ngā matua rerekē rānei, pērā i te PIR, ka piki ake te uaua o te whakaputa me te utu.
Ngā Taputapu mō te Hanga i ngā Paewhiri Hanawiti
He nui te pānga o ngā taputapu whakaputa ki te kounga o ngā panera hanawiti. Mā te raina whakaputa matatau me te whakauru ka pai ake te whakarite i te huka ōrite o te rauemi matua polyurethane me te whakakotahitanga o te pereti whakarewa o te rauemi matua.
Whakaritenga me ngā Āhuatanga Motuhake
He iti ake te utu o ngā panera PU paerewa nā te hanga aunoa. Ka tāpirihia te utu ki ngā rahi ritenga, ngā āhua ahurei, ngā kōtaha taha motuhake, ngā paninga matatau rānei mō te UV, te ārai-haukū, ngā whakaotinga hoahoa rānei.
Hei tauira, hei tāpiri atu ki ngā tikanga tuku ihongā panera hanawiti, Ka taea hoki e te Kamupene Dongan te whakarato i ngā panera hanawiti whakapaipai. Ka taea e ngā kiritaki te whiriwhiri, te whakarite rānei i te tauira o te kiri whakarewa kia rite ki ō rātou ake hiahia me te momo whare. Ko te hanga i ngā tauira ritenga ko te tikanga me hanga he pokepoke whakarewa motuhake, ā, ka whakaatuhia hoki te utu o te pokepoke ki te utu o te hua kua oti.
