Ka hoʻopili ʻana o ka Ammonium Polyphosphate i nā mea kinai ahi pauka maloʻo

ʻO Ammonium polyphosphate (APP) kahi hui inorganic i hoʻohana nui ʻia i nā mea pale ahi a me nā mea kinai ahi. ʻO kona ʻano kemika ʻo (NH4PO3)n, kahi e hōʻike ai ʻo n i ke kekelē o ka polymerization. ʻO ka hoʻohana ʻana o APP i nā mea kinai ahi e pili nui ana i kona mau waiwai pale ahi a me ka hoʻopau ʻana i ka uahi.

ʻO ka mea mua, ʻo ke kuleana nui o APP i nā mea kinai ahi he mea pale lapalapa. Kāohi ia i ka laha ʻana o nā lapalapa a me ke kaʻina hana puhi ʻana ma o nā ʻano hana like ʻole. Hoʻopau ʻo APP i nā mahana kiʻekiʻe e hana i ka waikawa phosphoric a me ka ammonia. Hoʻokumu ka waikawa phosphoric i kahi ʻili pale aniani ma luna o ka ʻili puhi, e hoʻokaʻawale ana i ka oxygen a me ka wela, a laila e pale ana i ka hoʻomau ʻana o ka puhi ʻana. Kōkua ʻo Ammonia i ka hoʻoheheʻe ʻana i ke kinoea hiki ke puhi ʻia ma kahi puhi a hoʻemi i ka mahana o ka lapalapa.

ʻO ka lua, he mau waiwai maikaʻi ko APP no ka hoʻopau ʻana i ka uahi. I loko o ke ahi, ʻaʻole wale ka uahi e hōʻemi i ka ʻike maka a hoʻonui i ka paʻakikī o ka pakele ʻana, akā aia pū kekahi i loko o ia mea he nui nā kinoea ʻawahia, e hoʻoweliweli nui ana i ke olakino kanaka. Hiki i ka APP ke hōʻemi pono i ka hana ʻana o ka uahi i ka wā o ke kaʻina hana puhi a hoʻemi i ka pōʻino o ke ahi.

Hoʻohana ʻia ka Ammonium polyphosphate i nā mea kinai ahi ma nā ʻano like ʻole, ʻo ka mea maʻamau o ia mau mea he mau mea kinai ahi pauka maloʻo a me nā mea kinai ahi huʻa. I loko o nā mea kinai ahi pauka maloʻo, ʻo ka ammonium polyphosphate kekahi o nā mea nui a ua hui pū ʻia me nā kemika ʻē aʻe e hana i kahi pauka maloʻo kinai ahi maikaʻi. Hiki i kēia pauka maloʻo ke uhi koke i ka mea e ʻā ana, hoʻokaʻawale i ka oxygen, a kinai koke i ka lapalapa. I loko o nā mea kinai ahi huʻa, ua hui pū ʻia ka ammonium polyphosphate me kahi mea hoʻohua e hana i kahi huʻa paʻa e uhi ana i ka ʻili o ka mea e ʻā ana, e pāʻani ana i kahi hana i ka hoʻoluʻolu a me ka hoʻokaʻawale ʻana i ka oxygen.

Eia kekahi, loaʻa i ka ammonium polyphosphate nā pono o ka palekana o ke kaiapuni a me ka haʻahaʻa o ka ʻawahia. Ke hoʻohālikelike ʻia me nā mea pale ahi halogenated kuʻuna, ʻaʻole hoʻokuʻu ka ammonium polyphosphate i nā halides ʻino i ka wā o ke ahi ʻana, e hōʻemi ana i ka pōʻino i ke kaiapuni a me ke kino kanaka. No laila, ua loaʻa i ka hoʻohana ʻana o ka ammonium polyphosphate i nā mea kinai ahi hou ka nānā nui ʻia.

Ma keʻano laulā, he nui nā pono o ka hoʻohana ʻana o ka ammonium polyphosphate i nā mea kinai ahi, me ka hana pale ahi kūpono, ka hopena hoʻopau uahi maikaʻi, a me ka palekana o ke kaiapuni a me ka haʻahaʻa o ka ʻawahia. Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻomaikaʻi ʻana i nā koi o ka poʻe no ka palekana a me ka palekana o ke kaiapuni, e ʻoi aku ka laulā o nā manaʻolana noi o ka ammonium polyphosphate i nā mea kinai ahi.
