He aha nā pono o ke kaula pale ahi?

Nā kaula pale ahi Hoʻohana pinepine lākou i kahi ʻano pālua a multi-layer paha, me nā mea kūikawā e like me nā lipine mica pale ahi i loko. Ke puka mai ke ahi, hiki i ka lipine mica ke hana i kahi ʻili pale paʻa i nā mahana kiʻekiʻe, e hoʻokaʻawale ana i ka lapalapa a me ka wela, a pale i nā alakaʻi kūloko a me nā papa insulation mai ka hōʻino ʻia, no laila e mālama ana i ka hana maʻamau o ke kaapuni. ʻAʻohe ʻano hoʻolālā pale ahi i hoʻolaʻa ʻia o nā kaula maʻamau a maʻalahi ke puhi ʻia i ke ahi, e alakaʻi ana i ka hoʻopau ʻana o ke kaapuni.

ʻO nā alakaʻi o nā kaula pale ahi ma ke ʻano laulā, hoʻohana lākou i nā mea hao keleawe a i ʻole nā ​​mea hao keleawe me kahi kiko heheʻe kiʻekiʻe, a he kiʻekiʻe hoʻi ke kūpaʻa ahi o nā mea insulation a me ka sheath, hiki ke kū i nā mahana kiʻekiʻe. No ka laʻana, hiki i nā mea insulation o kekahi mau kaula pale ahi ke noho paʻa i ka mahana kiʻekiʻe o 950 - 1000°C, e hōʻoiaʻiʻo ana e hiki i nā kaula ke hana maʻamau no kekahi manawa i loko o kahi ahi. I ka hoʻohālikelike ʻana, e heheʻe a hōʻino koke ʻia paha nā mea o nā kaula maʻamau i ia mau mahana kiʻekiʻe.

ʻO nā mea insulation i hoʻohana ʻia ma nā kaula pale ahi ʻaʻole wale ke kūpaʻa ahi akā ʻoi aku ka maikaʻi o ka hana insulation. ʻOi aku ka kiʻekiʻe o ke kūpaʻa insulation o kēia mau mea a me ka ikaika dielectric, hiki ke pale maikaʻi i ka leakage o kēia manawa a me nā hanana pōkole. Hiki i nā mea insulation o nā kaula maʻamau ke ʻike i ka emi ʻana o ka hana insulation i ka wā o ka hoʻohana lōʻihi a i ʻole i kahi mahana kiʻekiʻe, a he maʻalahi hoʻi i nā pōʻino palekana e like me ka leakage uila.

ʻO ka papa insulation o nā kaula pale ahi ʻO ka maʻamau he hana pale makū maikaʻi, hiki ke pale pono i ka makū mai ke komo ʻana i loko o nā kaula a pale i ka emi ʻana o ka hana insulation ma muli o ka makū. Ke hoʻohana ʻia nā kaula maʻamau i kahi ʻano pulu, hiki ke hoʻopilikia nui ʻia kā lākou hana insulation, a hiki ke hana ʻia nā hana hewa.

I mea e mālama ai i ka hana paʻa i nā wahi ʻino e like me ke ahi, nā kaula pale ahi ʻO ka maʻamau he ʻano palekana ikaika aʻe, e like me ka hoʻohui ʻana i ka pale kila kila a i ʻole ka pale uea kila, a pēlā aku. Hiki i kēia mau papa pale ke hoʻomaikaʻi i ke kūpaʻa compressive, tensile, a me ka hopena o nā kaula, e hōʻemi ana iā lākou i ka hōʻino ʻia ke kau ʻia i nā mana o waho. ʻAʻole like ka nui o nā kaula maʻamau me ia ʻano i hoʻoikaika ʻia, a he haʻahaʻa ko lākou ikaika mechanical.

ʻOiai e hōʻoiaʻiʻo ana i ka ikaika mechanical, nā kaula pale ahi ʻoi aku ka maikaʻi o ka maʻalahi o nā kaula, kahi kūpono no ke kau ʻana a me ke kau ʻana. ʻOiai i nā wahi uea paʻakikī, hiki ke kulou a kau ʻia me ka maʻalahi me ka ʻole o ka hōʻino ʻana i ke ʻano o loko o nā kaula ma muli o ke kulou nui ʻana. ʻOi aku ka maikaʻi ʻole o ka maʻalahi o nā kaula maʻamau, ʻoi aku hoʻi no kekahi mau kaula nui, a ʻoi aku ka nui o nā pilikia e loaʻa i ka wā o ke kau ʻana.

Ma muli o ka hoʻohana ʻana i nā mea hana kiʻekiʻe a me nā kaʻina hana hana holomua, nā kaula pale ahi ʻOi aku ka maikaʻi o ka pale ʻana i ka wā ʻelemakule ma mua o nā kaula maʻamau. I ka wā e hoʻohana lōʻihi ai, hiki iā lākou ke pale aku i ka mana o nā mea pili i ke kaiapuni (e like me nā kukuna ultraviolet, ka oxidation, nā loli o ka mahana, a pēlā aku), e hoʻolohi i ka wikiwiki o ka ʻelemakule ʻana o nā mea, a pēlā e hoʻolōʻihi ai i ke ola lawelawe o nā kaula. Ke hōʻike ʻia nā kaula maʻamau i nā wahi ʻino no ka manawa lōʻihi, hiki ke loaʻa nā pilikia e like me ka ʻelemakule ʻana o ka insulation a me ka haki ʻana o ka sheath, e hoʻopilikia ana i kā lākou hoʻohana maʻamau.

Nā kaula pale ahi hiki ke kū i nā mahana kiʻekiʻe, a ʻaʻole loli iki kā lākou hana ma lalo o nā mahana hana maʻamau a me nā mahana overload pōkole. ʻAe kēia iā lākou e hoʻohana ʻia i kekahi mau wahi wela kiʻekiʻe me ka ʻole o ka hoʻopōkole ʻana i ko lākou ola lawelawe ma muli o nā mahana kiʻekiʻe loa. I loko o kahi kaiapuni wela kiʻekiʻe, e hōʻemi koke ka hana o nā mea o nā kaula maʻamau, e hopena ana i ka pōkole nui o ke ola lawelawe o nā kaula.
