Me whakamahi ngā whare hou i ngā rauemi e whakakotahi ana i te haumaru, te kaha, te whakamarumaru, me te huruhuru kohatu.ngā panera hanawitihe kōwhiringa pai. He ātete ahi, he ārai haruru hoki. Heoi, he maha ngā ngoikoretanga o ngā panera huruhuru toka tuku iho, pērā i te mimiti wai me te kaha iti o ngā taha. Hei whakaoti i ēnei raruraru, kua puta mai he panera hanawiti huruhuru toka momo hou.
Ngā Painga
huruhuru tokangā panera hanawitikua roa e whakanuia ana mō ō rātou āhuatanga ātete ahi me te oro. He mea hanga mai i te toka basalt i rewa i te pāmahana neke atu i te 1,450°C, he pūtake kore-mura te huruhuru toka me te whakatauranga ahi o te Akomanga A1. Nā tēnei he mea tino pai mō ngā pakitara me ngā tuanui ātete ahi i roto i ngā whare ahumahi. I roto i ngā whakamātautau ahi, ka taea e te panera huruhuru toka 100 mm te tu atu i te mura tika mō te neke atu i te 2 hāora me te kore e pakaru te hanganga.
Ko tētahi atu painga nui ko te mimiti oro. Mā te hanganga muka o te huruhuru toka ka whakaitihia te haruru. Ka taea e te papa matotoru 50 mm te whakaiti i te tuku oro mā te 25–30 tekipere, ā, he pai mō ngā awheawhe whakaputa, mō ngā teihana hiko rānei.
He pono hoki te whakamarumaru wera. Ahakoa kāore i te rite te whai huatanga ki te pahuka PU, ka mau tonu te pāmahana o roto i ngā panera huruhuru toka. Ka tukuna e te panera 100 mm te kawe wera o te 0.042 W/m·K, he nui hei whakaiti i te whakamahinga pūngao i te nuinga o ngā āhuarangi.
He kaha anō hoki te ātete pēhanga o ngā panera huruhuru toka. Ko te matotoru toharite he 100–150 kg/m³, e homai ana he pumau hanganga teitei. He pai te ātete ki ngā kawenga hau me ngā pānga miihini.
Hei tāpiritanga, he pai mō te taiao. He nui te rauemi mata, arā, te pātarati, ā, ka taea te hangarua. Ka taea e ngā wheketere te whakamahi anō i ngā para huruhuru toka i te wā e hangaia ana, ka whakaiti i te pānga ki te whenua ururua.
Ngā ngoikoretanga
Ahakoa ngā kaha maha, he ngoikore tonu ngā panera huruhuru toka e whakawhāiti ana i tā rātou mahi. Ko te raru tino kitea ko te mimiti wai. Ka mimiti ngāwari ngā muka huruhuru toka i te makuku mai i te hau, ka piki ake te taumaha, ka whakaiti hoki i te uara whakamarumaru. I roto i ngā taiao makuku, ka piki ake te kawe wera mai i te 0.042 ki te 0.060 W/m·K, ka mate te pūngao tae atu ki te 30%.
Ka waikura anō hoki ngā mata whakarewa mēnā ka puta te haukū tata ki ngā taha i te mimiti wai. I roto i te wā, ka whakapotohia pea te roa o te ora o te panera.
Ko tētahi atu raruraru ko te pakarukaru o ngā taha. Kāore te matua huruhuru toka e piri pai ki ngā kiri maitai i ngā taha. I te wā e kawe ana, e tāuta ana rānei, ka pakaru, ka pakaru rānei ngā taha. Ehara i te mea ka pā noa tēnei ki te āhua engari ka whakaiti hoki i te ātete hau me te kaha.
Ko te hiri tētahi atu ngoikoretanga. Ki te kore e tika te tiaki, ka taea e ngā taha o ngā panera te turuturu i te makuku me te hau. Ka taea e tēnei te ngaronga o te wera, te tipu rānei o te harore.
Hei tāpiritanga, he nui ake te taumaha o ngā panera huruhuru toka i ētahi atu momo. Ko te taumaha o te panera huruhuru toka 100 mm te matotoru he 17–20 kg/m², ko te taumaha o te panera PU he rite te matotoru he 12–14 kg/m² anake. Ka nui ake te taumaha o ngā panera taumaha ki ngā anga hanga whare, ā, ka piki ake hoki ngā utu tāutanga.
Hei whakamutunga, me tapahi me te huihui tika te tukanga whakaputa. Nā te kore e pai te hononga i waenga i ngā rau maitai me te uho ka pakaru te wāhanga i raro i te wiri, i te pēhanga rānei.
Nā ēnei raruraru ka uaua ki ngā panera huruhuru toka te whakatutuki i ngā hiahia o ēnei rā mō te whai huatanga o te pūngao me te ātete ki te makuku, inā koa i roto i ngā rūma ma, i ngā rūma makariri, i ngā whare takutai makuku rānei.
Paewhiri Hanawiti Huruhuru Toka Momo Hou
I hangaia te panera hanawiti huruhuru toka taha PU hei whakakotahi i te ātete ahi o te huruhuru toka me te kaha hiri o te polyurethane. I roto i tēnei hoahoa, kua whakakīia ngā taha roa e rua o te panera ki te pahuka PU, ko te uho o waenganui ka noho tonu hei huruhuru toka.
Mā tēnei hanganga ranu ka ea ngā ngoikoretanga matua o ngā panera huruhuru toka tuku iho. Ka hangaia he hiri piri e ngā taha PU, ka ārai i te urunga o te wai me te hau. E whakaatu ana ngā whakamātautau he 60% te iti o te mimiti wai o ngā panera he taha PU ki te whakataurite ki ngā panera huruhuru toka noa. Ka pai ake te whai huatanga o te whakamahana ahakoa i ngā wāhi makuku nui.
Mā te hononga i waenganui i te taha PU me te pereti maitai ka kaha ake te kaha o te taha. He pai ake te ātete o ngā panera ki te pānga i te wā e whakahaeretia ana, e tāutahia ana hoki. Hei tauira, i roto i ngā whakamātautau wheketere, kāore he kino o te taha i roto i ngā panera taha PU i te hekenga 1 mita, engari i kitea ngā pakaru i roto i ngā panera huruhuru toka paerewa.
Ka whakarei ake hoki te taha PU i te ātete hau o te pūnaha panera. Ka piri te taha pahuka ki ngā panera tata, ka whakaiti i te turuturu wera. Mā tēnei ka pai ake te mahi i roto i te rokiroki makariri, i ngā awheawhe ma, me ngā whare tari.
Ko tētahi atu painga ko te pai ake o te tāutanga. Ko ngā taha PU he hononga hiri taiao, e whakaiti ana i te hiahia mō ngā rīpene silicone, rapa rānei. Ka taea e ngā kaiwhakauru te whakauru tere ake i ngā panera, ka penapena i ngā utu mahi mā te 10–15%.
Mā te whakakotahi i ngā kaha o ngā rauemi e rua, ka tutuki i te panera hanawiti huruhuru toka taha PU te ātete ahi teitei, te tiaki makuku pai ake, me te pakari ake—katoa i roto i te hanganga kotahi.
Ngā Āhuatanga Hangarau
Ka tukuna e ngā panera huruhuru hipi taha PU ngā whakapainga ka taea te ine puta noa i ētahi tohu mahi matua.
Te mahi wera. Ka whakaitihia e te taha PU te hononga wera. Ko te kawe wera toharite o te panera 100 mm he 0.037 W/m·K, tata ki te 12% te iti iho i ngā panera huruhuru toka tuku iho. Ka puta he penapena pūngao kitea i roto i ngā whare hauhautanga, whare pouaka whakamātao rānei.
Ātete ahi. Ahakoa ngā taha PU, kei te mau tonu te uho i te huruhuru toka, e whakarato ana i te tiaki kore-mura. E whakaū ana ngā whakamātautau ahi kei te mau tonu te whakatauranga ahi Akomanga A mō ngā pakitara me te Akomanga B mō ngā tuanui. I roto i te whakamātautau 120-meneti i te 1,000°C, i mau tonu te āhua o te panera me te kore e horapa te mura.
Mahi ā-wai. He nui ake i te 95% te tere o te pūtau-kati o ngā taha PU. Ka ārai pai tēnei hanganga i te urunga o te makuku. I muri i te 24 hāora o te rumaki wai, he iti iho i te 1% o te taumaha i mimitihia e ngā panera taha PU, ko ngā panera huruhuru toka paerewa ia i mimitihia tae atu ki te 6%.
Te kaha o te hanganga. Ka piki ake te kaha o te here i waenga i ngā kiri maitai me te matua mai i te 0.09 MPa ki te 0.13 MPa me te hoahoa taha PU. He pai ake te ātete o ngā panera ki te piko me te pēhi, kia mau ai te mahi i roto i ngā hanganga whānui.
Te pakari me te āhua. Mā te taha PU ka ātaahua te āhua o ngā hononga o te panera, ka ārai i te kohikohinga puehu me te waikura. He mea nui tēnei i roto i ngā wheketere kai me ngā rūma ma.
Ngā Taupānga me ngā Auahatanga o te Mākete
Kua rongonui haere ngā panera hanawiti huruhuru hipi taha PU i roto i ngā kaupapa hanga hou. Nā te ātete ki te ahi me te tiaki i te makuku, he pai mō ngā wheketere, ngā whare putunga, me ngā whare tūmatanui.
I ngā wāhi e pāngia ana e ngā aituā ahi pērā i ngā whare ahumahi me ngā whare putunga mahi, kua noho te panera huruhuru toka hei taurangi nui mō te haumaru ahi. E 120 meneti te roa o te tiaki ahi me te haumākū pumau o roto i ngā panera, ā, ka whakaitihia te tere hapa o ngā wāhanga tairongo mā te 8%.
Ka whai hua anō hoki ngā rūma makariri me ngā pokapū rokiroki kai i tēnei hangarau. Mā ngā taha PU ka hiritia pai, ka whakaitihia hoki te piki me te heke o te pāmahana. Nā te putanga mai o ngā panera hanawiti huruhuru hipi PU kua whakaratohia he kōwhiringa hou mō te hoahoa me te hanganga o te rokiroki makariri. Me te kore e whakararu i ngā āhuatanga whakamarumaru o te tinana rokiroki makariri, ka tino whakarei ake te mahi haumaru o te rokiroki makariri.
He mea nui te akuaku i roto i ngā rūma ma me ngā hōhipera. Ka āraihia e ngā panera taha PU te puehu me te huakita kei uru mā roto i ngā āputa. Ka māmā ake, ka tere ake hoki te horoi i ngā taha maeneene.
I te mea ka kaha haere ngā paerewa hanga whare o te ao, ka nui ake ngā kaiwhakawhanake e whiriwhiri ana i ngā rauemi ranu pēnei i ngā panera huruhuru hipi taha PU. Ka tautokohia e te ia o ngā mahi ngā tiwhikete hanga whare matomato me ngā whāinga penapena pūngao. He maha ngā kaihanga e tuku ana i ngā panera o ngā matotoru maha (50–150 mm) me ngā tae hei whakatutuki i ngā hiahia hoahoanga.
Ka whakaoti paitia ēnei raruraru e te panera hanawiti huruhuru toka taha PU. Mā te tāpiri i ngā taha polyurethane, ka whakapakari i te hiri, ka whakapai ake i te whakamarumaru, ka roa ake hoki te roa o te ora. I te tipu haere o te tono mō ngā rauemi hanga kounga teitei, ka whai wāhi nui ngā panera huruhuru toka taha PU ki te whakatupuranga e whai ake nei o te hanganga haumaru, whai hua, me te pumau.
