Kohinga o ngā rae whai kaihanga puhi rākau

Apr 17, 2025

Te whakawhanakei i te urupa o ngā pūtōru mea rākau e tukua ana ki te paearu UL (whakaae hia e te tohu UL) me mātau tonu ki ngā tikanga mō te kaha hei whakatetonga i te ahi (UL 10C/UL 10B), te rohu, te pai noa iho mō te taiao (EPA/LEED), ā, me te pai mea. Ki runga i ngā ture pērā i te NFPA 80 me te ASTM E84, ko ngā mahi nui hei whakawhanake i te urupa o ngā pūtōru mea rākau ko te whakapai i te mea kia kino te ahi, te kawe i te kahikatoa hei whakatetonga i te ahi, me te tirotiro mō te tiaki. Ko tēnei hei whai wā ka kitea te pai o te whakatetonga i te ahi, ā, ka tiakina hoki te whakaheke o te whare i roto i te ahi.

Te hunga whakangungu matua

1. Te whakamutunga i te papa whakamua

Te kawe rākau:

Me whakamahi i te rākau tuatahi (pērā i te tawa, te kauri) rānei, i te papa rākau whakatetonga i te ahi (e whai whakaaetanga ana i te ture ANSI/HPVA HP-1).

Kāore e mohiotia te waehu wai ki waenganui i te 8% ki te 12% (hei whakamutunga i te whakarerekē me te whakapakaru).

Whanaketanga here kauhere (pūtake matua):

Paerewa hiko here tangata

Momo here kauhere: Ammonium phosphate, borate rānei ko te amino resin tipa (e taurite ana ki te ASTM E84 Rōpū A).

Ko te aukaha o te whanaketanga ≥ 5mm (ki te whai wāhi i te āhua here kauhere o te pūtake).

Te whakawāhi herehere i roto i te kōhure (kia whai ake te whiuwhiutanga o te rēitini).

I muri i te tīmata whakarērea, me whai ake i te whakamātau wāhi tuhituhi moemoeā (kia kaua e whakarerekē i muri iho).

Kōpaki kaiponuhi

Pūponuhi ponuhi whakapiri

Ko te pūnui o te kōpaki he 0.5 ki te 1.2mm (ki te nui rawa atu, e āheinga ana ki te waehae i waenganui i ngā pūtaka).

Ka whairopi ia 5 ki te 10 wa i te wa e whakamahia ana ki te ahi, e hanga nei etahi rākau karbona hei rapa whē (tirohia e te whakamataki UL 10C).

Puti kei roto i te whiuwhiu

Ka whakamahia hei tae i ngā pōro o te miro me te whakapai i te whakaheke kākāriki (me whai ngā taumata moe ahi ki te tinana o te maru huihui).

3. Te mahi whakakī rākau

Lameketā huarere whiuwhiu (HPL)

Kei te waewae 0.8-1.5mm te rahau. Kei te whakatū tonu ia ki te wāhi hāpori nui me ngā kōpanga (whakaae ana e te whakamātau UL 72).

Nga wāhi e taea ana: ngā wāhi i te nui rawa o ngā huarere, pērā i ngā whare rongoā me ngā kura.

Rakau tuatahi + uwhi matekai

Ko te rahau he 0.6 ki te 1.0mm, āpiti matekai kua whakauru ki runga i te rārangi i raro.

Ko te top coat he uwhi UV matekai māori (VOC < 100g/L, e pai ana ki ngā ture EPA).

Whakaputu takotoora teka huka

Tōmua mō te rautaki pakihi, i whakaputuia ki te taiao huka kawepepea (mahere tahuri-āhuarangi).

Nga Kīwahanatanga Matatika

Matatika o te kawepepea:

I whai wāhanga i te whakamātau kawepepea UL 10C (nuinga 20/45/90 min).

Te mohiotanga o te kohu i te wā e hua ana (ASTM E662) ≤450, ā, e whakarite ana te tokihi me te ture o te NFPA 286.

Whakaaro moemoea rāpoi taiao

Kāore te whakamahana ahi i te formalokī hei whakarite ki ngā pūtake TSCA Title VI, ā, kāore hoki i ngā mete nui.

Ko te waehanga VOC o te kaiwhakatōrangi he iti i te 250g/L (EPA 40 CFR Part 59).

Tohu matihiko

Whakamātau whakarite i te rereke wai (ASTM D4585): Kore hākari i muri i te 500 waehora.

Whakahē i te pāpaku (Taber Abrasion) ≥500 raupapa (HPL finish).

Iv. Tirohanga ki te Whanaketanga me te Tirohanga

Whakamātau kua oti nei te whakatūhia i te tae huka: Nawe ā-wheako, me tatau i te roa o te kuhu iho.

Te kīreki ake o te kōwhiri ahi: Te whakamahi i te whakaaturanga huaki (ASTM D3359) ≥4B rauemi.

I muri i te whakamatau whakarite huihuinga, kua tirotirohua: kāore i whakatūtū ngā rāngai, ā, kua pūmau tonu te lāpā karboni.

V. Whakahaere me te Tiaki

Ka whai wā koe i te whakapai, whakamahia tōnati whakapai tuhituhinga (pH 6~8) kia kaua e whakakēkeke te kaweārangi.

Whakahokiwhakaatuhia ngā totohu tahataha i runga i te waahi e kore ana kia poroiti (nā ngā waehanga i roto i te pouaka huihuinga e whakaaroaro ana i te paihikanga huihuinga).

Me whakatika i ngā whakatekoteko whenu ki te kaweārangi matekai i te wā e taea ana te whakawhiti i te paihikanga.

Vi. Whakarāpopototanga

Te whanonga taumataiti o ngā kōpu kiwahi Ametia rā neke atu ki te tirohanga i te māuiuitanga, whakamahia ai ngā āhuatanga nui ake me te tirotiro hoki i te taiao. E pai ana te kawe i te whiringa i runga i te wāhi whakamahi (pērā i ngā whare hanga porihitanga, ngā whare hanga mahi pakihi rānei rānei ko ngā whakapai matua), me whakaae tino ki ngā paerewa UL, NFPA me te ASTM hei whakamana i te kaitiakitanga haumanu i te wā o te ahi.
