PU me te PIR polyurethanerokiroki makaririE mōhiotia whānuitia ana ngā panera hei rauemi whakamarumaru tino whai hua mō ngā hanganga rokiroki makariri o ēnei rā. Nā te iti rawa o te kawe wera me te pumau o te hanganga, koinei te otinga pai mō ngā whare rokiroki makariri reo me te nui.
Nā te whakamahinga whānui o ngā panera polyurethane, kua tino pai ake te kounga tiaki i ngā pūnaha whakahaere mekameka makariri hou, me te whakaiti hoki i ngā utu whakahaere whānui. He mahi nui tā ēnei panera i roto i ngā hanganga mekameka makariri e penapena ana i te pūngao puta noa i ngā rāngai kai, rongoā, me te ahumahi.
Te Mahi Ārai Tino Pai o ngā Paewhiri Rokiroki Matao Polyurethane
Ko te painga whakataetae matua o ngā panera rokiroki makariri polyurethane kei roto i tōna hanganga moroiti pūtau-katia o roto. E hiahiatia ana e ngā paerewa ahumahi kia eke ngā panera polyurethane kounga teitei ki te tere o te pūtau-katia neke atu i te 95 ōrau. Ka hangaia e te kaihoko pahuka he pūwero moroiti hiri i roto i te rauemi matua, ā, ka ārai pai ēnei pūwero i ngā ara whakawhiti wera. Nō reira, he tino iti tonu te whakawhiti wera i waenga i roto me waho o te taiao rokiroki makariri.
Nā te nui o te ōwehenga pūtau-kati, ka eke ngā panera polyurethane ki te taumata kawe wera i waenga i te 0.018 me te 0.024 W/m·K. Ko ngā rauemi whakamahana tuku iho pērā i ngā papa huruhuru toka, ngā panera polystyrene EPS rānei, ka whakaatu i ngā uara kawe wera i waenga i te 0.035 me te 0.045 W/m·K. I raro i ngā whakaritenga whakamahana ōrite, ka taea e ngā panera polyurethane te whakatutuki i te mahi whainga me te tata ki te haurua o te matotoru o ngā rauemi tuku iho. Mā tēnei painga ka whakaiti tika i te whakamahinga wāhi o te whare, ā, ka whakapai ake i te rahinga rokiroki ka taea te whakamahi.
Ka whakatauritehia hoki e ngā panera rokiroki makariri polyurethane te mahi whakamahana me te kaha ā-ringa mā te whakahaere i te kiato rauemi. Ko te tikanga ka mau tonu te kiato pahuka o ngā panera kounga teitei i waenga i te 38 me te 40 kg/m³. Ko tēnei awhe he taurite pai i waenga i te pakari o te hanganga me te whai huatanga o te wera. Ka ngoikore te kaha pēhi i te kiato iti, ka nui ake te tūponotanga o te whakarerekētanga. Ka piki ake te kawe wera me te utu rauemi i te kiato teitei, engari kāore e whakarato i ngā painga ōrite.
Ngā Whakatakotoranga Hangarau me ngā Horopaki Taupānga
Ko te tikanga, ka hangaia e ngā kaihanga ngā panera rokiroki makariri polyurethane mā te here i te pahuka polyurethane mārō i waenganui i ngā paparanga e rua o ngā rau maitai kua peitahia. Mā tēnei hanganga hiato ka whakaratohia he whakamarumaru me te pakari o te mata. Ko te whiriwhiri matotoru o te panera e whai ana i ngā aratohu tino pakari e ahu mai ana i te pāmahana.
Ko ngā panera he matotoru 50 ki te 100 mm te pai mō ngā taiao rokiroki hou i runga ake i te 0°C. Ko ngā rūma rokiroki matao e mahi ana i te taha o te -18°C, me whai panera i waenga i te 100 me te 150 mm te matotoru. Mō ngā whare putunga huka tere, ngā whare pāmahana tino iti rānei i raro i te -25°C, he maha ngā wā ka tohua e ngā miihini he panera matotoru mai i te 150 ki te 200 mm. Mā ēnei whirihoranga ka mau tonu te pāmahana o roto, ā, ka ārai i te ngaronga nui o te pūngao.
Ko te kaha pēhi tonu tētahi atu tawhā nui i roto i te hoahoa rokiroki makariri. Me tautoko e ngā panera ngā kawenga mai i ngā pūnaha whata, ngā mīhini whakapūngao, me ētahi atu taputapu kua tāutahia. Ko ngā panera rokiroki makariri polyurethane kounga teitei ka eke ki ngā uara kaha pēhi neke atu i te 150 kPa. Mā tēnei taumata ka whakarite i te pono o te hanganga mō te wā roa i te wā e mahi tonu ana.
Ka pāngia hoki te kōwhiringa rauemi e te haumaru ahi. Ko te nuinga o ngā panera rokiroki makariri polyurethane rongonui e tutuki ana i ngā paerewa ātete ahi B1, B2 rānei. Ka tineia aunoatia ngā rauemi taumata B1 i roto i ngā hēkona e toru i muri i te tangohanga o te mura. Ka tineia aunoatia ngā rauemi taumata B2 i roto i ngā hēkona e toru ki te ono. Ka whakaitihia e ēnei āhuatanga te mōrearea o te horapa o te ahi, ā, ka whakapai ake i te haumaru whānui o te whare.
Ko te pumau o ngā rauemi te mea e wehewehe ana i ngā panera kounga teitei. Ko te pumau o ngā panera rokiroki makariri polyurethane te tikanga ka pupuri i ngā reiti mimiti wai i raro i te 1 ōrau. Ka mahi pono hoki rātou i roto i te whānuitanga o te pāmahana mai i te -60°C ki te +120°C. Mā tēnei pumau ka mau tonu te mahi whakamahana i raro i ngā āhuatanga mahi uaua me te huringa pāmahana auau.
Ngā Painga Hanganga: Hangarau Hononga Arero-me-Awaawa Kua Whakamātauhia
Ko ngā piriti makariri tētahi o ngā tūmomo mōrearea nui ki te whai huatanga o te rokiroki makariri. Ka arohia tēnei take e ngā panera rokiroki makariri polyurethane mā roto i ngā pūnaha hononga arero-me-rua kua oti te whakakotahi me ngā tikanga raka rerekē kua hangaia ki roto. Mā ēnei pūnaha ka taea e ngā panera te piri tahi me te hanga i tētahi paparanga whakamarumaru tonu.
Mā tēnei hoahoa hanganga ka tino pai te mahi hiri hononga. Ina tāpirihia e ngā kaiwhakauru ngā rīpene hiri ngaio me ngā whakakī pahuka, ka heke te turuturu o te hau me te ngaronga makariri i ngā hononga ki ngā taumata iti rawa. Mō tētahi whare rokiroki makariri e kapi ana i te 1,000 mita pūrua, ka taea e ngā panera polyurethane kounga teitei te whakaiti i te whakapaunga hiko ā-tau mā te 20 ki te 30 ōrau ki te whakataurite ki ngā rauemi whakamahana noa. Ko te tikanga o tēnei whakaiti he painga ōhanga nui mō te wā roa me te hokinga tere o te haumi.
