Ka whakawhirinaki te umanga panera hanawiti ki ngā rauemi whakakī mahi-teitei e whakarato ana i te whakamarumaru, te ātete ahi me te pumau hanganga. Ngā whakakorikori polyurethane (hei tauiraMXC-5, MXC-8, MXC-41) he mahi nui tā rātou i roto i te hanga o ēnei rauemi, e āwhina ana ki te whakatutuki i ngā tauhohenga matū tere ake, whai hua ake hoki i roto i te tukanga hanga pahuka. Ko ngā rauemi e whakamahia whānuitia ana i roto i te matua hanawiti ko ngā rauemi kore-waro pērā i te polyurethane (PUR), te polyisocyanurate (PIR), te polystyrene, te pahuka phenolic (PF) me te huruhuru toka. Ka whakaratohia e tēnei pepa he tirohanga whānui mō ēnei rauemi me te pēhea e taea ai e ngā whakakorikori polyurethane te āwhina i tō rātou whanaketanga me te tono i roto i ngā panera hanawiti.
Ngā Rauemi Whakakī Noa mō ngā Paewhiri Hanawiti
Ka taea te wehewehe i ngā rauemi e whakamahia ana i roto i ngā matua o te papa hanawiti ki ngā wāhanga matua e rua: ngā rauemi pahuka me ngā rauemi muka kore-ora. He āhuatanga ahurei tō ia momo rauemi e pai ai mō ngā tono motuhake, i runga i ngā whakaritenga ā-wera, ā-hanganga, me te ātete ahi o te papa.
Ngā Rauemi Pahuka
1. Polyurethane (PUR) me te Polyisocyanurate (PIR):
Ko te Polyurethane (PUR) me te polyisocyanurate (PIR) ngā rauemi e rua e whakamahia whānuitia ana i roto i te hanga o ngā panera hanawiti. Ka puta ēnei rauemi mā te tauhohenga o ngā polyol me ngā isocyanate i whakakorikoria e ngā matū pēnei i te MXC-5,MXC-8, me MXC-41. Mā te mahi whakatere ka whakawhanui, ka whakamaroke, ka piri pai te pahuka ki roto i te hanganga pereti hanawiti.
- Te Piritanga me te Pūmautanga Hanganga:Ko tētahi o ngā take matua mō te whakamahi i te PUR/PIR i roto i ngā panera hanawiti ko ōna āhuatanga pai mō te here. I te wā e whakapūpū ana, ka piri pai te PUR me te PIR ki ngā rauemi mata pērā i te maitai, te konumohe rānei, ā, ka whakarei ake i te hanganga o te panera. Nā tēnei āhuatanga ka waiho ēnei pahuka hei whiringa whānui mō ngā raina whakarārangi, nā te mea he mea nui te here kaha mō te pumau.
- Te Ātete Ahi Whakapai Ake:Kua pai ake te hanganga matū o te pahuka PUR/PIR i ngā tau kua pahure ake nei, me tōna ātete ahi hoki, he āhuatanga nui mō ngā tono hanga whare e tika ana kia tutukihia ngā ture haumaru ahi tino pakari. He pai ake te ātete ahi o te PIR i te PUR, ā, he whānuitia te kōwhiringa mō ngā tono mōrearea nui.
2. Porohitarene (EPS/XPS):
Ko te polystyrene, tae atu ki te polystyrene whānui (EPS) me te polystyrene extruded (XPS), he rauemi pahuka anō e whakamahia ana i roto i ngā panera hanawiti. Ahakoa kāore i te whakamahia whānuitia pērā i te PUR/PIR, he tino pai ngā āhuatanga whakamahana o te polystyrene. Heoi, kāore ōna āhuatanga piri i te kaha pērā i te PUR/PIR, nō reira kāore pea i te pai mō ngā tono e hiahia ana ki te kaha hanganga teitei.
- Ārai Wera:He pai rawa te ārai wera o te polystyrene i te utu iti iho i ērā atu rauemi, ā, he mea rongonui mō ngā kaupapa utu iti. Heoi, kāore i te rite te ātete ahi me te kaha piri ki te PUR me te PIR.
3. Pahuka Phenolic (PF):
He mea hou te pahuka phenolic ki te whakatauritea ki ētahi atu rauemi pahuka, ā, he onge te whakamahinga i roto i te hanga papa hanawiti. Heoi, kotahi te painga nui: he ātete ahi pai rawa atu. Ko te pahuka phenolic te ātete ahi pai rawa atu i roto i ngā rauemi pahuka, ā, he pai mō ngā tono e matua ana te haumaru ahi.
- Ātete Ahi:Nā te hanganga matū ahurei o te pahuka phenolic ka taea e ia te tu atu i ngā pāmahana teitei ake me te kore e whakararu i te hanganga. Ahakoa tōna kaha ahi pai rawa atu, kāore i te whakamahia whānuitia te pahuka phenolic nā te mea he nui ake te utu me te iti o te wātea.
Ngā Rauemi Muka Kore-Paraoa
1. Huruhuru toka:
Ko te Rockwool, he rauemi muka kore-waro, e whakamahia ana i roto i ngā matua o te papa hanawiti nā tōna ātete ahi me ōna āhuatanga whakamarumaru haruru. Kāore i rite ki ngā rauemi pahuka, kāore te Rockwool e mura, ā, he mea pai mō ngā mahi ahi-kore.
- Ārai Wera me te Oro:He pai te whakamarumaru wera o te Rockwool, ahakoa kāore i te rite te teitei ki ētahi rauemi pahuka. Hei tāpiri, ka āwhina tōna hanganga muka ki te whakaiti i te oro, kia pai ai mō ngā mahi e hiahia ana kia whakaitihia te haruru.
- Ātete Ahi:Ko te painga matua o Rockwool ko tōna kore e mura. Ka taea e ia te tu atu i ngā pāmahana tino tiketike, ā, he mea pai mō ngā whare e hiahia ana kia whakapakarihia te ārai ahi.
Te Tūranga o ngā Whakakōkī Polyurethane i roto i te Hanganga o ngā Paewhiri Hanawiti
He mea nui ngā whakakorikori polyurethane pēnei i te MXC-5, MXC-8, me te MXC-41 mō te whakaputanga pai o ngā rauemi pahuka e whakamahia ana i roto i ngā panera hanawiti. Ka whakaterehia e ēnei whakakorikori ngā tauhohenga matū i waenga i ngā polyol me ngā isocyanates, kia pai ai te horapa o te pahuka, kia pakari ai hoki. Ki te kore he whakakorikori, ka puhoi, ka kore e oti te tauhohenga, ka hua ake he pahuka kounga iti me ngā āhuatanga here me te whakamarumaru kāore i te tika.
- Mana Tauhohenga:Ka whakahaerehia e ngā matū whakakorikori te tere o te hanganga o te pahuka, kia tino whānui ai te pahuka kia whakakīia te pūtake katoa o te papa hanawiti. Ka whai pānga anō hoki rātou ki te taurite i waenga i ngā tauhohenga pupuhi me te whakakī, kia pai ake ai te kiato me te hanganga pūtau o te pahuka.
- Ngā Whakaaroaro Taiao:He maha ngā whakakōkī polyurethane hou kua hangaia hei whakaiti i ngā tukunga matū waro mimiti (VOC) me te whakapai ake i te haumaru taiao. Ko ngā whakakōkī iti-kakara, kore-tukunga, pērā i te MXC-41, ka whai wāhi ki te hanga panera hanawiti e pai ana ki te taiao.
Whakamutunga
I roto i te hanga o ngā panera hanawiti, he mea nui te whiriwhiri i te rauemi whakakī tika hei whakatutuki i ngā whakaritenga haumaru wera, hanganga, me te ahi. He painga motuhake kei ngā rauemi pahuka pēnei i te PUR, PIR, polystyrene, me te pahuka phenolic, me ngā rauemi kore-ora pēnei i te rockwool. He mahi nui tā ngā whakakorikori polyurethane pēnei i te MXC-5, MXC-8, me te MXC-41 ki te whakarite i te hanga pai o ngā rauemi pahuka mahi-teitei. Ka tere ake ēnei whakakorikori i ngā tauhohenga matū e hanga ana i te pahuka, ka whakarato i te hononga pai ake, te whakamarumaru wera, me te ātete ahi e tika ana mō ngā tono hanga hou.
