Ma ke ʻano he mea pale ahi maikaʻi loa a pili i ke kaiapuni, ua hoʻohana nui ʻia ka wai-soluble ammonium polyphosphate (APP) i nā kula he nui i nā makahiki i hala. ʻO kāna ʻano kemika kūʻokoʻa e hiki ai iā ia ke decompose i loko o ka polyphosphoric acid a me ka amonia i nā wela kiʻekiʻe, e hana ana i kahi papa carbonized paʻa, hoʻokaʻawale maikaʻi i ka wela a me ka oxygen, a laila e pale ai i ka hopena o ka puhi ʻana. I ka manawa like, loaʻa iā APP nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa, halogen-free, a me ka uahi haʻahaʻa, e hoʻokō ana i nā koi hoʻomalu kaiapuni hou.
Ma ke kahua o ke kūkulu ʻana, hoʻohana nui ʻia ka APP hoʻoheheʻe wai i ka intumescent ahi-retardant coatings a me ka lapalapa ahi-retardant panels, me ka hoʻomaikaʻi nui ʻana i ka pale ahi o nā mea. Ma ka ʻoihana textile, hāʻawi ʻo APP i nā lole maikaʻi loa i nā waiwai pale ahi ma o ka impregnation a i ʻole nā kaʻina hana uhi, a kūpono i nā huahana e like me nā lole ahi a me nā pale. Eia kekahi, hiki ke hoʻohana ʻia ka APP i nā lako uila, nā huahana plastik a me nā māla ʻē aʻe e hāʻawi i ka pale ahi hilinaʻi no nā mea like ʻole.
Me ka hoʻopaʻa ʻana i nā lula palekana kaiapuni, ke hoʻomau nei ka ulu ʻana o ka mākeke no ka wai-soluble ammonium polyphosphate. I ka wā e hiki mai ana, me ka hoʻonui hou ʻana i ka ʻenehana, e pāʻani ka APP i kahi kuleana koʻikoʻi i nā kula hou aʻe a paipai i ka hoʻomohala ʻana i nā mea pale ahi i nā kuhikuhi ʻōmaʻomaʻo a maikaʻi.
Ka manawa hoʻouna: Mar-10-2025
