He aha a Nomex? Te muka Aramid ātete ahi
E whakapono ana ngā kaipatu ahi me ngā taraiwa waka reihi ki tēnei mea, e whakawhirinaki ana ngā kairangi moana me ngā hōia ki tēnei mea—nō reira, he aha te mea ngaro kei muri i te papanga Nomex? He mea whatu mai i ngā unahi tarakona, he tino pai rānei ki te tākaro ki te ahi? Kia hurahia te pūtaiao kei muri i tēnei whetu rongonui e ātete ana ki te mura!
▶ Te Whakataki Taketake o te Kakahu Nomex
Kakahu Nomex
He muka aramid ātete-mura te Nomex Fabric, he mea hanga ki te muka aramid ātete-mura, he mea hanga ki te muka aramid i whakawhanakehia e DuPont (ināianei ko Chemours) i te Hononga o Amerika.
He tino ātete ki te wera, ki te ahi, ā, he pumau ki ngā matū—ka mura, kaua e tahuna ina pāngia e te mura—ā, ka taea te tu atu i ngā pāmahana tae atu ki te 370°C, me te mea he mama, he manawa hoki.
E whakamahia whānuitia ana te papanga Nomex i roto i ngā hūtu tinei ahi, ngā taputapu hōia, ngā kākahu tiaki ahumahi, me ngā hūtu reihi, ā, e mōhiotia ana ko ia te paerewa koura mō te haumaru nā tōna mahi whakaora ora pono i roto i ngā taiao tino kino.
▶ Tātaritanga Āhuatanga Rauemi o te Kakahu Nomex

He papanga Nomexmeta-aramidmuka hangai i whakawhanakehia eDuPont(ināianei ko Chemours). He mea hanga mai ite poly-meta-phenylene isophthalamide, he momo pūmua ātete wera, ātete mura hoki.
Kāore,NomexmeKevlarkāore i te rite, ahakoa he rite tonu rāuangā muka aramidi whakawhanakehia e DuPont, ā, he rite tonu ētahi āhuatanga.
Āe,He tino ātete a Nomex ki te wera, he mea tino pai mō ngā tono e tino nui ana te tiaki i a koe mai i ngā pāmahana tiketike me ngā mura.
He whānuitia te whakamahinga o Nomex nā tōnate ātete wera tino pai, te tiaki mura, me te roame te mea he mama, he whakamarie hoki.
1. Te Ātete ki te Mura me te Wera Kāore e Taea te Whakaōrite
Kāore e rewa, e maturuturu, e mura rāneingāwari—engari,whakapūmau waroina pāngia e te mura, ka hanga he ārai tiaki.
Ka ātete ki ngā pāmahana tae atu ki370°C (700°F), he mea tino pai mō ngā taiao e pāngia ana e te ahi.
2. Te Whakatio-ā-Whaiaro, ā, e Tutuki ana i ngā Paerewa Haumaru
E tutuki ana kiNFPA 1971(ngā taputapu tinei ahi),EN ISO 11612(te tiaki wera ā-umanga), meTAU 25.853(te mura o te rererangi).
Whakamahia i roto i ngā tono kei reirangā ahi mura, ngā pewa hiko, ngā tauhiuhi whakarewa rewa rāneihe mōrearea.
3. Māmā, ā, he whakamarie mō te mau roa
He rerekē a Nomex i te asbestos matotoru, i te fiberglass rānei.manawa, ngāwari hoki, e āhei ai te nekeneke haere i roto i ngā mahi mōrearea nui.
He maha ngā wā ka konatunatua kiKevlarmō te kaha tāpiri, mō tengā whakaoti ātete-parumō te whaihua.
