Ma ke ʻano he mea pale ahi kūpono loa a aloha i ke kaiapuni, ua hoʻohana nui ʻia ka ammonium polyphosphate (APP) wai-soluble ma nā ʻano he nui i nā makahiki i hala iho nei. ʻO kona ʻano kemika kū hoʻokahi e hiki ai iā ia ke hoʻokahe i loko o ka waikawa polyphosphoric a me ka ammonia i nā mahana kiʻekiʻe, e hana ana i kahi papa carbonized mānoanoa, e hoʻokaʻawale pono ana i ka wela a me ka oxygen, a laila e pale ana i ka hopena puhi. I ka manawa like, loaʻa iā APP nā ʻano o ka haʻahaʻa haʻahaʻa, ʻaʻohe halogen, a me ka uahi haʻahaʻa, e hoʻokō ana i nā koi palekana kaiapuni o kēia wā.
Ma ke kahua o ke kūkulu ʻana, hoʻohana nui ʻia ka APP wai-hoʻoheheʻe ʻia i nā uhi pale ahi intumescent a me nā panela pale ahi, e hoʻomaikaʻi nui ana i ke kūpaʻa ahi o nā mea. Ma ka ʻoihana lole, hāʻawi ʻo APP i nā lole i nā waiwai pale ahi maikaʻi loa ma o ka impregnation a i ʻole nā kaʻina hana uhi, a kūpono no nā huahana e like me nā lole ahi a me nā pale. Eia kekahi, hiki ke hoʻohana ʻia ʻo APP i nā mīkini uila, nā huahana plastik a me nā kahua ʻē aʻe e hāʻawi i ka pale ahi hilinaʻi no nā mea like ʻole.
Me nā lula palekana kaiapuni e paʻa mau ana, ke hoʻomau nei ka ulu ʻana o ke koi mākeke no ka ammonium polyphosphate hiki ke hoʻoheheʻe ʻia i ka wai. I ka wā e hiki mai ana, me ka hoʻonui hou ʻana o ka ʻenehana, e pāʻani ʻo APP i kahi kuleana koʻikoʻi ma nā kahua hou aʻe a paipai i ka hoʻomohala ʻana i nā mea pale ahi i nā kuhikuhi ʻōmaʻomaʻo a me ka pono.
