Ngā Matāwhero Whakamahia i te Mahi Whakapuhua o ngā Kauhanga Tūmatawhero UL

Pūtango ahi UL, e whakatupu ana hei tae atu ki ngā paerewa tirotiro whenua nui ake a Underwriters Laboratories (UL), he mea nui mo te whakaiti ahi me te haumanu tonu i ngā nohoanga. E whai pānga ana enei pūtango ki te kauru rākau rānei, ki te kōpaki ahi, ki te whakapuakitanga tuhinga, me te whakaae ki ngā paerewa tirotiro o te UL. He pai rawa anō kia kitea he mea nui ko te UL kaore i whakaaetia i ngā rerekē hoki o ngā rākau hei hanga i ngā pūtango. Ko te tino whakaaro o ngā paerewa ANSI/UL 10B, ANSI/UL 10C me EN 1634-1 kei te whakamana i te mahi whanui o te pūtango ahi, ahakoa te momo rākau. Me whai mana ngā pūtango ahi ki ngā whakamātau ahi, ki ngā whakamātau whakarite, me ngā whakamātau whakataunga ahi.

Kei raro nei tētahi whakaaturanga mō ngā rākau matua e whai wāhi ana ki te hanga i ngā pūtango ahi UL rākau me te toto.

Pūtango Ahi Rākau

Nā ngā pūtango ahi rākau e whakawhanake ana i te āhua me te whakapuakitanga ahi, ka whai wāhi tonu ki ngā wāhi e pai ana ki te āhua. Pērā i te pūtango miharoiti, i te pūtango whare kura. Nā ngā rākau e whai wāhi ana:

Ngā kiriwhara: Ngā kiriwhara mēhake o ngā rākau whakatōpū, nō te mea he kiriwhara hanganga rākau, pērā ko te kauri, ko te tawai, ko te birikete, ka whakamahia ki roto i te mata o te wāhi hei whakapai i te āhuatanga. Ka tirotiro haere ngā kiriwhara nei hei whakaora i te whiu ahi, nā reira ka noho pai te taumanu.

rākau Whakapiki Kiriwhara (LVL): Ko tēnei te wāhanga rākau tuatahi o te wāhi ahi. Kei waho, kei roto hoki i tēnei ngā rerekētanga e whakarite ana i te ahi. He mea nui tēnei hei whakatū tonu i te mana moana o te wāhi rākau i te waahi.

Kōpu Minita: Hei whakahaere i ngā tohu ahi nui atu, ka whakamahi te kōpu minita e whai ana i ngā rerekētanga pērā ko te kālaisilikaete rānei ko te magineziu okside, hei whakatū tonu i te whiu ahi me te whakarite ā-rohe.

Ngā Pūngao: Ka whakamahi ngā pūngao kawe ahi, e ai ki te tikanga he pūngao fenoleti rānei he urea formalide resini, hei whakapai i ngā kauwhau o te wāhi. Ka noho pai ngā pūngao nei i runga i ngā waehu ahi nui, kia tutuki ai te wāhi i te wā o te ahi.

Te Whakawehenga Wero: Ka whakamahia ngā rauemi whakariterite rākau ki te whakawehenga wero hei tiaki i te tahitanga o te pūtahi me te whakatangataki i te whiuwhiutanga.

Papanui Mateahi: Ka hanga hoki ngā papanui mateahi i runga i ngā rauemi minera. Ka whakamahia hei kaihua i waenganui i te tinana o te pūtahi me ngā wāhanga rākau matua. Ka whakamahia anō hei rautaki maimoa mō te whiuahi o te paepae pūtahi.

Wāhi tūru ahi tangata rākau

Ka whakanuia ngā pūtahi ahi tangata hei tohu i te whiuwhiutanga me te whiuahi matika, e whai ana i ngā tuhituhinga ā-motu me ngā tuhituhinga ā-porihanga. E ai ki ngā rauemi:

Tāngata Ahi: Ko te tāngata ahi te raraunga nui mō ngā pūtahi ahi, e āhei ana ki waenganui i te 16 ki te 20 gauge. Ko te kawepeke hinu kōpana hei whakahē i te kōpūtanga, e tiakina ana te whiuwhiutanga moe roa, me te tāngata hei whakatū tonu i te mana ā-kaupapa me te whiuahi matika mō ngā ratonga e āhei ana ki te 3 rā.

Māteria ota: Nō te nuinga, he ota mineral, ota fiberglass rānei, he kaihanga honeycomb kraft paper i roto i ngā pūtango ahuwhenua. He pai tētahi ota mineral, e whai wāhi ana i te huringa ā-hua o te wera. He motu kei te maha rawa te ota fiberglass, nō reira ka motu kei te maha rawa hoki te whakatika i te mana moana, me te whakapakari i te whiu.

Pūtake whakamutunga: Tae atu ki ngā pūtango rakau, ka whakamahi ngā pūtango ahuwhenua ki ngā pu take whakamutunga i roto i ngā pūtake graphite rānei, na sodium silicate, hei whakamutunga i ngā waewae i runga i te ahi, hei tirotiro i te kinoitiiti o te ahi rānei.

Māteria o ngā taonga whakapakari: Ka whakamahi ngā whakapakari ahuwhenua, pērā i ngā whakapakari ahuwhenua rānei, hei whakarite i te whakawāhi. Ko ēnei ko ngā mea e whai ana i te galvanized steel i raro i te kiri pūtango.

Ko tātou ko XZIC (Shanghai Xunzhong Industry Co., Ltd.). Tātou ngā kaiwhakapuaki i te mahi ki ngā pūtango ahi. Kua whakaritea e tō mātau kāwanatanga 50,000 wāhi o ngā pūtango ahi inoi me 20,000 wāhi o ngā pūtango ahi rākau ia tau. Kei tātou ngā tohu UL tuatahi rawa i Aotearoa. Nga pūtango ahi matatika pai, ka whakauru hei whakamana i ngā ture o te Amerika me Kanata. Pūtango ahi inoi ā-3 rā kia noho ahi, pūtango ahi rākau he 90 meneti. Anō hoki ka hanga tātou i ētahi atu pūtango mō te nohohanga. Inā ka taea te whakatakoto.
