Mō te hanganga o te papa hanawiti, he mea nui te whiriwhiri i te rauemi matua tika hei whakarite i te mahi e hiahiatia ana e pā ana ki te ārai wera, te ārai haruru, te ārai ahi, me te kaha. He rerekē te hanganga o ngā rauemi matua, he rerekē ngā painga o ia rauemi i runga i ngā whakaritenga motuhake o te tono.
Ngā Paewhiri Matua Huka
Ngā matua pahuka, inā koapolyurethane(PUR) me te polyisocyanurate (PIR), kei roto i ngā kōwhiringa rongonui mō ngā panera hanawiti.PolyurethaneHe tino pai ngā āhuatanga whakamahana tuatahi o ngā panera matua, ā, he mea tino pai mō ngā tono e matua ana te whai huatanga o te pūngao. Heoi, he iti noa iho te ātete ahi ki ērā atu rauemi. Hei whakatika i tēnei, i whakawhanakehia ngā panera PIR hei putanga whakapai ake o te PUR, e tuku ana i te ātete ahi, te whakamahana wera, me te pumau. He pai ngā panera PIR mō ngā tono ahumahi me ngā tono kāinga e hiahia ana ki te haumaru ahi pai ake.
Ahakoa he nui ake te utu o ngā rauemi matua o te pahuka phenolic (PF) i te PUR me te PIR, he pai ake te ātete ahi me te whakamarumaru wera ake. He maha ngā wā ka whiriwhiria ēnei panera ina he mea nui te tiaki ahi, ahakoa he mea whakaaro pea te utu teitei i roto i ngā kaupapa e aro nui ana ki te tahua.
He huarahi ōhanga ngā panera matua pahuka polystyrene, inā koa ko te polystyrene whānui (EPS) me te polystyrene extruded (XPS). He whānuitia te whakamahinga o ngā panera EPS i roto i ngā kaupapa utu iti engari he iti ake te ātete ki te wera me te ahi i te PUR, i te PIR rānei. I tētahi atu taha, he nui ake te mātotoru o te XPS, he pai ake te ātete ki te wera, te makuku, me te mamaoa i te EPS, ā, he pai ake te kōwhiringa mō ngā taiao e pāngia ana e te makuku.
Ngā Paewhiri Matua Kore-Huka
Mō ngā tono e aro nui ana ki te ātete ahi me te whakamarumaru oro, ka tū motuhake ngā panera matua huruhuru kohuke. He rauemi kore-mura te huruhuru kohuke, he pai te tiaki ahi me te ārai oro. Heoi, he taumaha ake i te PIR, ā, he iti ake te whakamarumaru wera, he pai ake mō ngā kaupapa e aro nui ana ki te ātete ahi i te pai o te wera.
Ngā Paewhiri Matua o te Honikoma
Ko ngā hanganga honikoma, he mea hanga noa mai i te konumohe, te polypropylene, te kāri rānei, e mōhiotia ana mō te ōwehenga kaha-taumaha teitei, he mea pai mō ngā tono e tino hira ana te kaha ā-ringa. Heoi, kāore e rite te taumata o te whakamarumaru wera ki ngā panera pahuka, ā, kāore e tino pai mō ngā kaupapa e matua ana te whakamarumaru wera.
Hei whakarāpopototanga, ko te whiriwhiri i te rauemi matua e whakawhirinaki ana ki ngā whakaritenga motuhake o te kaupapa. He tino pai ngā matua PUR me PIR mō te whakamahana wera, ko te huruhuru kohuke ia he tino pai ki te ātete ahi me te whakamahana haruru. Mō ngā tono e aro ana ki te kaha, he pai ake pea ngā matua honikoma, ahakoa kāore i te pai te whakamahinga wera. He huinga painga motuhake kei ia rauemi matua, ā, ko te kōwhiringa pai rawa atu e whakawhirinaki ana ki te taurite o ngā hiahia mahi pēnei i te whakamahana, te haumaru ahi, me te hanganga.
