Kua noho ngā panera hanawiti huruhuru toka taha PU hei wāhanga nui o te hanganga hou, hei whakataurite i te haumaru ahi, te whai huatanga o te pūngao, me te pakari. Ka whakakotahihia e ēnei panera te matua huruhuru toka me te hiri taha PU hei whakatika i ngā wero mahi noa e pā ana ki ngā panera hanawiti huruhuru toka tuku iho.
Te Mārama ki ngā Paewhiri Hanawiti Huruhuru Toka
Ko ngā panera hanawiti huruhuru toka he paparanga matua whakamarumaru huruhuru toka e piri ana i waenganui i ngā mata whakarewa e rua, he maitai kua pania ki te tae, he maitai kua pania ki te tae rānei. Ko te huruhuru toka tonu he mea hanga mai i ngā rauemi toka me ngā rauemi kohuke tūturu kua rewa, kua mirohia hei muka e whakarato ana i te ātete ahi me te mahi wera pai rawa atu. Ko te kawe wera o te matua huruhuru toka kei waenganui i te 0.035–0.043 W/m·K.
Ko tētahi o ngā painga nui o ngā panera huruhuru toka ko tōna kaha ki te ahi. Ko te huruhuru toka he rauemi kore-mura Akomanga A e tu atu ana i ngā pāmahana neke atu i te 1000°C me te kore e horapa te mura, he mea tino pai mō ngā hanganga he tino kaha ngā whakaritenga haumaru ahi.
Haunga te whakamarumaru wera, he pai ake te mahi oro o te huruhuru toka i ngā rauemi matua rerekē. Me te mahi whakamarumaru oro noa e eke ana ki te RW = 29–30 dB mō ngā panera me ngā matua kiato 120 kg/m³,ngā panera huruhuru tokaāwhina ki te waihanga i ngā whare marino ake i roto i ngā taiao ahumahi me ngā taiao arumoni.
Te Wero o ngā Paewhiri Hanawiti Huruhuru Toka
Ahakoa ēnei kaha, he uaua anō hoki ngā panera hanawiti huruhuru toka. Nā te hanganga muka me te porowhita tūturu ka ngoikore pea rātou ki te uruhanga makuku mena kāore i te hiritia tika ngā taha.
I te wā e pāngia ana e te haumākū, ka mimiti te huruhuru toka i te wai, ka whakaiti i te uara whakamarumaru, ā, ka arahi pea ki te tipu o te harore. Ka akiakihia e tēnei herenga ngā whakapainga pērā i te hiri taha me te hoahoa hononga pai ake.
Haunga tēnā, he ngoikoretanga anō hoki ō ngā panera hanawiti huruhuru toka. Hei tauira, he taumaha ake i ētahi o ngā matua pahuka, he nui ake ngā kawenga hanganga me ngā utu kawe.
Ko te kawe wera he nui ake i ngā pahuka pūtau-katia kounga teitei pērā i te polyurethane. Ko te tikanga he maha ngā wā e hiahiatia ana he panera matotoru ake hei whakatutuki i te mahi whakamarumaru ōrite.
Kāore ēnei ngoikoretanga e whakakore i te uara o ngā panera huruhuru toka, engari me aro atu ngā kaihoahoa me ngā kaihanga ki ēnei ngoikoretanga.
Ngā Otinga me te Tūranga o te Hangarau Hiri Tapa PU
Hei whakatika i ngā herenga o ngā panera hanawiti huruhuru toka paerewa, ka whakatinanahia e ngā kaihanga me ngā miihini he raupapa o ngā otinga whai hua:
Ngā whakapainga hoahoa hononga. Mā te tāuta i ngā ārai whakarewa ki ngā taha e rua o te panera hanawiti. Ka hangaia e ngā ārai me ngā panera he hanganga whakauru hanganga mā roto i ngā hononga arero-me-awa, ka whakapai ake i te ātete hau o te matua huruhuru toka.
Hirihia ngā taha ki te polyurethane. Mā te paninga PU i ngā taha o te panera ka hangaia he ārai tonu e whakaiti ana i te urunga o te makuku, te turuturu o te hau, me te urunga o te puehu. Ka whakaitihia hoki te hononga wera me te tiaki i te matua huruhuru toka mai i ngā kino o te taiao.
Ka taea e ēnei tikanga te whakaoti i ngā raruraru e pā ana ki ngā panera huruhuru toka tuku iho, engari he rerekētanga anō hoki. Nā ngā āhuatanga ā-tinana o te rauemi matua huruhuru toka, he maha tonu ngā āputa i roto i te panera hanawiti huruhuru toka me ngā ārai whakarewa. Ina koa mō ngā panera tuanui huruhuru toka, he mārama ake tēnei hapa.
Ko ngā raraunga ahumahi mō ngā panera taha PU e whakaatu ana i ngā whakapainga ka taea te ine i roto i ngā inenga mahi. Hei tauira, ko ngā panera huruhuru toka hiri-taha e pupuri ana i ngā uara whakamarumaru oro ≥30 dB me ngā whakatauranga ahi Akomanga A, ko te hiri taha e tiaki ana i te matua mai i te makuku i roto i ngā huringa ratonga roa.
He maha ngā wā ka whakakotahi ngā kaihanga i ēnei rautaki me ngā mahi tāutanga pakari, kia tika ai te tūnga o ngā panera, kia hiritia, kia whakauruhia hoki ki ngā rama me ngā ārai kohu hei whakanui ake i ngā putanga mahi mō ngā tekau tau o te whakamahinga.
Te Mahi a ngā Paewhiri Hanawiti PU Edge Rock Wool me ō rātou Painga
Ka wehewehea ngā panera hanawiti huruhuru toka taha PU mā te hangarau kua tohua ki ngā atanga matua o ngā panera. Ka whakauruhia e te hanganga matua te huruhuru toka ki te rauemi hiri taha polyurethane kua pania ki ngā taha katoa o ngā panera. Ko te polyurethane, e mōhiotia ana mō tōna piripono me tōna ngāwari, ka hanga he hononga pakari i waenga i ngā kiri whakarewa me te matua whakamarumaru, ka tiaki pai i ngā wāhi ngoikore.
He maha ngā mahi nui a te taha PU:
Ārai i te makuku. He hiri wai-kore te taha PU hei ārai i te urunga o te wai. Ko te huruhuru hipi anake ka ngāwari ki te mimiti i te makuku, nō reira ka tino whakaitihia tēnei mōrearea e te ārai polyurethane.
Te whakapai ake i te mahi wera. Mā te whakaiti i te urunga o te hau me te hononga wera i ngā hononga o te panera, ka whakarei ake te ātete wera whānui o te huihuinga ki ngā mea kē atu kāore i hiritia.
Whakakaha ā-mīhini. Mā te tukanga here taha ki te polyurethane, ehara i te mea ka whakapai ake i te ātete hau o te rauemi matua anake, engari ka whakakaha hoki i te poraka huruhuru toka i te taha, ka whakaiti i te marere o te taha. Ka whai wāhi te hiri taha ki te pakari o te panera, ka āwhina ki te ātete i te whakarerekētanga i raro i te kawenga, me te whakarei ake i te ātete hiki i te hau.
Ka tautokohia e ēnei āhuatanga ngā inenga mahi e whakahuatia ana e ngā kaihanga. Hei tauira, ko ngā panera he 100 mm te matotoru o te matua e whakaatu ana i ngā uara kawe wera tata ki te 0.41 W/m²·K, e whakataurite ana i te whakamarumaru me te taumaha hanganga.
Ki te whakaritea ki ngā panera huruhuru toka kāore he hiri taha, he roa ake te ora o ngā panera taha PU, neke atu i te 15 tau, he iti ake ngā take tiaki, ā, he pai ake te ātete ki te makuku i ngā taiao makuku, takutai rānei. Nā ēnei āhuatanga ka tino pai ngā panera hanawiti huruhuru toka taha PU mō ngā whare ahumahi, ngā whare mekameka makariri, ngā taunga rererangi, ngā wāhi hākinakina, me ngā whare arumoni kei reira ngā kaupapa matua ko te mahi roa me te haumaru.
