Rangahau mō te Ātete Mura o ngā Rauemi Waka me ngā Auahatanga Whakamahinga o ngā Muka Ātete Mura i roto i ngā Waka

I te tere o te whanaketanga o te umanga motuka, kua noho ngā motuka—e whakamahia ana mō te haereere, mō te kawe taonga rānei—hei taputapu tino nui i roto i te oranga o te tangata. Ahakoa he mea whakangāwari ngā motuka, he tūponotanga haumaru anō hoki, pērā i ngā aituā waka me te mura ohorere. Nā te iti o te wāhi me ngā rauemi mura o roto, ina puta he ahi i roto i te waka, he uaua ki te whakahaere, ka mōrearea te oranga me ngā taonga o ngā pāhihi. Nō reira, me tino aro atu ngā kaiwhakamahi ki te haumaru ahi i roto i ngā waka.

Ko ngā take o ngā ahi i roto i ngā waka ka taea te whakarōpū kia:
(1) Ngā āhuatanga e pā ana ki te waka, tae atu ki ngā hapa hiko, ngā turuturu wahie, me te waku miihini i puta mai i ngā whakarerekētanga, ngā tāutanga, ngā tiakitanga rānei kāore i te tika.
(2) Ngā āhuatanga o waho, pērā i ngā tukinga, ngā takahurihuri, te tahunga tinana, ngā pūtake mura rānei kāore i te tiakina.

Ko ngā waka pūngao hou, he pākahiko kaha-pūngao nui tō rātou, he tino ngāwari ki te mura nā ngā ara iahiko poto i puta mai i ngā tukinga, ngā poka, te rere wera mai i ngā pāmahana teitei, te nui rawa rānei o te iahiko i te wā e utu tere ana.

01 Rangahau mō te Ātete ki te Mura o ngā Rauemi Waka

I tīmata te rangahau i ngā rauemi ārai mura i te mutunga o te rautau 19 i te Hononga o Amerika. Nā te whanaketanga o te hangarau i ngā tau tata nei, kua puta he tono hou mō te rangahau mō te ārai mura o ngā rauemi o roto o te motuka, ko te nuinga i roto i ēnei wāhanga e whai ake nei:

Tuatahi, ko te rangahau ariā mō te ātete mura. I ngā tau tata nei, kua aro nui ngā kairangahau i Haina ki te ako i ngā tikanga mura o ngā momo muka me ngā kirihou, tae atu ki te whakamahinga o ngā ātete mura.

Tuarua, te whakawhanaketanga o ngā rauemi ātete mura. I tēnei wā, he maha ngā momo rauemi ātete mura kei te whakawhanakehia. I te ao whānui, kua whakamahia angitu ngā rauemi pēnei i te PPS, te muka waro, me te muka karāhe puta noa i ngā ahumahi rerekē.

Tuatoru, rangahau mō ngā papanga ātete mura. He ngāwari te hanga i ngā papanga ātete mura, ā, he tino whai hua. Ahakoa kua tino whanakehia ngā papanga miro ātete mura, he iti tonu te rangahau mō ētahi atu papanga ātete mura i Haina.

Tuawhā, ngā ture me ngā tikanga whakamātautau mō ngā rauemi ātete mura.

Ka taea te wehewehe whānui i ngā rauemi o roto o te motuka ki ngā wāhanga e toru:

1. Ngā rauemi kei roto i te muka (hei tauira, ngā nohoanga, ngā whāriki, ngā whitiki nohoanga)—koinei te mea e whakamahia whānuitia ana, ā, e pā tika ana ki ngā pāhihi.
2. Ngā rauemi kei runga i te kirihou.
3. Ngā rauemi kei runga i te rapa.

He tino mura ngā rauemi muka, ā, e tata ana ki ngā pāhihi, ā, he nui ngā mōrearea ina puta he ahi. Hei tāpiri, ko ētahi wāhanga o te waka, pērā i ngā pākahiko me ngā miihini, kei te taha o ngā rauemi kakahu, ka piki ake te tūponotanga o te horapa o te ahi. Nō reira, he mea nui te ako i te ātete mura o ngā rauemi o roto o te waka hei whakaroa i te mura me te whakarato i te wā mawhiti mō ngā pāhihi.

02 Te Whakarōpūtanga o ngā Muka Ārai Mura

I roto i ngā mahi kakahu ahumahi, he nui te wāhi e whakamahia ana e ngā kakahu motuka. Tata ki te 20–40 kg o ngā rauemi o roto o tētahi motuka pāhihi, ko te nuinga he kakahu, tae atu ki ngā taupoki nohoanga, ngā urunga, ngā whitiki nohoanga, me ngā okiokinga upoko. He hononga tata ēnei rauemi ki te haumaru o ngā taraiwa me ngā pāhihi, e hiahiatia ana he āhuatanga ātete mura hei whakaroa i te horapa o te mura me te whakanui ake i te wā mawhiti.

Ngā muka ārai murae tautuhia ana ko ngā muka kāore e mura, e kore rānei e tahuna katoa ina pā atu ki te pūtake ahi, he iti noa ngā mura e puta ana, ā, ka tere te tineia i a ia anō ina tangohia te pūtake ahi. Ko te Taupū Hāora Whakawhāiti (LOI) te mea e whakamahia whānuitia ana hei ine i te mura, ā, ko te LOI i runga ake i te 21% e tohu ana i te iti o te mura.

E rua ngā momo muka ārai mura:

1. Ngā muka ātete mura tūturu
   Kei roto i ēnei muka he rōpū ārai mura kua hangaia ki roto i ō rātou mekameka pūmua, e whakarei ake ana i te pumau o te wera, e whakanui ake ana i ngā pāmahana pirau, e pehi ana i te whakaputanga hau mura, ā, e whakatairanga ana i te hanganga waro. Ko ētahi tauira ko:

• Ngā muka aramid (hei tauira, para-aramid, meta-aramid)
• Ngā muka polyimide (hei tauira, Kermel, P84)
• Ngā muka Polyphenylene sulfide (PPS)
• Ngā muka Polybenzimidazole (PBI)
• Ngā muka melamine (hei tauira, Basofil)

Kua hangaia papatipu kētia ngā muka meta-aramid, polysulfonamide, polyimide, me te PPS i Haina.

1. Ngā muka ātete mura kua whakarerekētia
   Ka ātete ēnei muka ki te mura mā roto i ngā tāpiringa, i ngā maimoatanga mata rānei, tae atu ki:

• Polyester ātete mura
• Nairona ātete mura
• Viscose ātete mura
• Polypropylene ātete mura

Ko ngā tikanga whakarerekētanga ko te copolymerization, te whakaranu, te miro hiato, te tāpiri, me te whakaotinga-muri.

03 Ngā Whakamahinga o ngā Muka Ārai Ahi Mahi-Tiketike i roto i te Tiakitanga Waka

Me tutuki i ngā rauemi ārai mura o ngā motuka ngā whakaritenga motuhake nā te iti o te wāhi. Kāore i rite ki ētahi atu whakamahinga, me ātete ēnei rauemi ki te mura, me whakaatu rānei i ngā tere mura kua whakahaeretia (hei tauira, ≤70 mm/min mō ngā waka pāhihi).

Hei tāpiri, ko ngā whakaaro ko:

• He iti te matotoru o te paowa, he iti hoki ngā tukunga hau paitinihei whakarite i te haumaru o ngā pāhihi.
• Ngā āhuatanga ārai-pūmauhei ārai i ngā ahi e puta mai ana i te kohu wahie, i te puehu rānei e kohia ana.

E whakaatu ana ngā tatauranga e 20–42 m² te rahi o ngā rauemi kakahu e whakamahia ana e ia motuka, e tohu ana i te nui o te pūmanawa tipu o ngā kakahu motuka. Ka whakarōpūtia ēnei kakahu ki ngā momo mahi me ngā momo whakapaipai, me te aro nui ki te mahi - inā koa te ātete mura - nā runga i ngā āwangawanga haumaru.

E whakamahia ana ngā papanga ātete mura teitei i roto i:

• Ngā taupoki nohoanga
• Ngā panera tatau
• Ngā taura potae
• Ngā pēke hau
• Ngā arai tuanui
• Ngā rauemi ārai haruru me te whakamahana

Ko ngā papanga kore-whatu i hangaia mai i te polyester, te muka waro, te polypropylene, me te muka karāhe, e whakamahia whānuitia ana hoki i roto i ngā whakapaipai motuka.

Mā te whakatairanga i ngā roto o ngā waka ātete ahi, ehara i te mea ka whakarei ake i te haumaru o ngā pāhihi engari ka whai wāhi hoki ki te oranga o te hapori.
