ʻO nā hiʻohiʻona e koho ai i nā mea e hoʻopaʻa ʻia ai nā mea hoʻonaninani

Mea kākau: DG Master- hale hōʻikeʻike i nā mea hana

ʻO nā mea pale ahi ma ka hōʻike mea hoʻonani i haku ʻia me nā kumu kumu, decentralized medium, flame retardant, auxiliary agent, filling, solvent, etc. He aha ke ʻano o nā mea pale ahi e koho ʻia i nā hale hōʻikeʻike nani e hoʻokō i nā koi o ka hale kūʻai? ʻO ka mea kumu ka mea hoʻokumu kiʻiʻoniʻoni nui, e komo pū ana nā mea hoʻopili inorganic (silicate, phosphate, etc.) a me nā mea hoʻopili organik (organic synthetic resin).

ʻO ka pale ahi kahi mea nui o nā uhi pale ahi. ʻElua ʻano o nā uhi pale ahi: hoʻokahi ka pena i hoʻopaʻa ʻia. He polymer kēia me ka pale ahi ikaika.

Hoʻokumu ia i kahi ʻāpana pale hoʻopaʻa ma ka ʻili o ka lāʻau. Hoʻopili pololei ka lāʻau ʻoki i ka lapalapa, akā ʻaʻole hiki ke pale i ka piʻi ʻana o ka wela o ka lāʻau. Ke hoʻomāhana a hoʻonui ʻia ka ea i loko o ka ʻāpana lāʻau, e luku ʻia ke kiʻi pena, a e nalowale ka hopena o ka lapalapa ahi.

ʻO ka ʻaʻahu keʻena hōʻike nani a i ʻole ke kāpī ʻana i ka mea pale ahi ma ka ʻili o ke keʻena hōʻike nani. ʻAʻole pono e mālama ʻia kēia ʻano hana me ka pale ahi. Ma muli o ka mānoanoa o ka mea, hiki i ka palaki ʻana a i ʻole ke kāpīpī ke hana i kahi ʻāpana pale ahi liʻiliʻi ma luna o ka ʻili o ka lāʻau, ʻaʻole hiki ke hoʻokō i ka hopena pale ahi.

Inā mālama ʻoe i ka papa hoʻokahi, ma o ka hōʻiliʻili ʻana, hiki i ka hoʻonui ʻana i ka nui o ka lāʻau lapaʻau ke hōʻoia i ka loaʻa ʻana o kahi hopena ahi. No ka laʻana, hoʻomaʻamaʻa mua ʻia ka mālama ʻana i ka lapalapa ahi o ka plywood a me ka veneer. I nā makahiki i hala iho nei, ua hui pū ʻia me nā adhesives e hoʻokō i ke kumu pale ahi.

ʻO ke ʻano o ka mālama ʻana i ka ʻili o nā hale hōʻikeʻike nani i hoʻohana mau ʻia i nā hale hōʻikeʻike nani, ʻo ia nā uhi pale ahi. Eia kekahi, e ʻelemakule ana ke kiʻi pena ma lalo o ka hana a nā mea kaiapuni no ka manawa lōʻihi, a pono e mālama mau i ka kiʻi pena ma mua o ka hana ʻana. ʻO ka mea ʻē aʻe he uhi hoʻonui.

ʻAʻa koke kēia ʻano uhi ma mua o ke ahi, e hana ana i ke kinoea hiki ʻole ke puhi, a ua hoʻonui koke ke kinoea. ʻO ke keʻena hōʻike nani e hana i kahi papa pale ma luna o ka ʻili o ka lāʻau, e paʻakikī ai i nā kinoea puhi i hana ʻia e ka hoʻoheheʻe wela o ka lāʻau. ʻAʻole hiki ke hana i ka lapalapa ahi, maikaʻi ka hopena o ka lapalapa ahi.

Eia nō naʻe, ʻaʻohe hiʻohiʻona maikaʻi o kēia uhi a pono e mālama pinepine ʻia no ka mālama ʻana i nā hopena pale ahi. Hoʻokumu ʻia kekahi mau uhi hoʻonui ʻia me nā polymer polymer kūlohelohe a i ʻole i hoʻohui ʻia, hoʻohui i ka huʻihuʻi, ka mea hoʻohāhā, ke kumu kalapona a me nā mea ʻē aʻe e pale ai i ke ahi. Hiki iā ia ke hana i ka ʻaʻahu a me ka mānoanoa o ka honeycomb a i ʻole ke ʻano o ka sponge-shaped charcoal layer ma lalo o ka hana o ke ahi.

ʻAʻole i loaʻa wale i kēia ʻāpana pua ka pale oxygen maikaʻi, akā loaʻa pū kekahi hopena insulation thermal maikaʻi. He palupalu a palupalu kēia ʻōhū, me ka plasticity nui, a ʻaʻole maʻalahi ka haki ʻana o ka wela wela. He kiʻekiʻe kēia ʻano o ka pale ahi, akā liʻiliʻi ka nui.
