Ammonium Polyphosphate (APP)
ʻO ka Ammonium Polyphosphate (APP) he mea hoʻohana maʻamau i ka lapalapa ahi, hoʻohana nui ʻia i nā uhi pale ahi intumescent.ʻO ka uhi hoʻopaʻa ahi intumescent he mea pale ahi kūikawā.ʻO kāna hana nui, ʻo ia ka hana ʻana i kahi papa insulation wela ma o ke kinoea pale ahi i hana ʻia e ka hoʻonui ʻana i mea e pale ai i ka laha ʻana o ke ahi a pale i ka pōʻino i nā hale i ke ahi.
Kumukānāwai
Hoʻohana ʻia ʻo Ammonium polyphosphate ma ke ʻano he pale ahi nui i loko o nā uhi pale ahi intumescent.ʻO ka ammonium polyphosphate he mau mea pale ahi maikaʻi.Ke piʻi ka mahana, e decompose ia e hana i ka waikawa phosphoric a me ke kinoea amonia.Hiki i kēia mau huahana ke hoʻoheheʻe i ka mea ola i loko o ka lanahu, a laila e hoʻokaʻawale i ka oxygen a me ka wela, a pēlā e hana ai i kahi hopena ahi.I ka manawa like, nui ka ammonium polyphosphate.I ka wā e wela ai a hoʻoheheʻe ʻia, e hoʻohua mai ia i ka nui o ke kinoea, i mea e hoʻokumu ai ka uhi ahi intumescent i kahi ʻāpana kalapona pale ahi ahi, e hoʻokaʻawale pono i ke kumu ahi mai ka hoʻopili ʻana a pale i ke ahi mai ka laha ʻana.
Nā pono
ʻO ka Ammonium polyphosphate ka maikaʻi o ke kūpaʻa wela maikaʻi, ka wai a me ka pale ʻana i ka wai, ʻaʻohe mea ʻawaʻawa a me ka haumia ʻole i ke kaiapuni, no laila ua hoʻohana nui ʻia i nā uhi ahi intumescent.Hiki ke hoʻohui ʻia i ka mea kumu o nā pale pale ahi e hana i kahi ʻōnaehana pale ahi holoʻokoʻa me nā mea pale ahi ʻē aʻe, nā mea hoʻopili a me nā mea hoʻopihapiha.Ma keʻano laulā, hiki i ka hoʻohana ʻana i ka ammonium polyphosphate i loko o nā uhi pale ahi intumescent hiki ke hāʻawi i ka retardancy ahi maikaʻi loa a me nā hiʻohiʻona hoʻonui, a mālama pono i ka palekana o nā hale a me nā hale i ke ahi.
Palapala noi
E like me nā mea like ʻole e koi ʻia ma APP, ʻO ka noi ʻana o ka ammonium polyphosphate i ka uhi ʻana i ʻike nui ʻia i:
1. Intumescent FR uhi ma ka hale kūkulu hale kila.
2. Ka lole lole hope i nā pale, ka uhi ʻeleʻele.
3. Uea FR.
4. Hoʻohana nui ʻia i ke kūkulu ʻana, ka mokulele, ka uhi ʻana o nā moku.
ʻO ke kumu hoʻohālike o ka uhi intumescent
