ʻAmonium Polyphosphate (APP)
ʻO ka Ammonium Polyphosphate (APP) kahi mea pale ahi i hoʻohana nui ʻia, hoʻohana nui ʻia i nā uhi pale ahi intumescent. ʻO ka uhi pale ahi intumescent kahi uhi pale ahi kūikawā. ʻO kāna hana nui ka hana ʻana i kahi papa pale wela ma o ke kinoea pale ahi i hana ʻia e ka hoʻonui ʻana e pale i ka laha ʻana o ke ahi a pale i ka hōʻino ʻana i nā hale ke hiki mai ke ahi.
Kumumanaʻo
Hoʻohana ʻia ka Ammonium polyphosphate ma ke ʻano he mea pale ahi nui i nā uhi pale ahi intumescent. He mau waiwai pale ahi maikaʻi ko Ammonium polyphosphate. Ke piʻi ka mahana, e palaho ia e hana i ka waikawa phosphoric a me ke kinoea ammonia. Hiki i kēia mau huahana ke hoʻomaloʻo i nā mea olaola i loko o ke kalapona, a laila e hoʻokaʻawale i ka oxygen a me ka wela, a laila e hana ana i ka hopena pale ahi. I ka manawa like, he ākea hoʻi ka ammonium polyphosphate. Ke hoʻomehana ʻia a palaho ʻia, e hana ia i ka nui o ke kinoea, i mea e hana ai ka uhi pale ahi intumescent i kahi papa kalapona mānoanoa pale ahi, kahi e hoʻokaʻawale pono ai i ke kumu ahi mai ka hoʻopili ʻana a pale i ke ahi mai ka laha ʻana.
Nā Pōmaikaʻi
Loaʻa i ka Ammonium polyphosphate nā pono o ke kūpaʻa wela maikaʻi, ke kūpaʻa i ka wai a me ka makū, ʻaʻohe ʻawahia a ʻaʻole hoʻohaumia i ke kaiapuni, no laila ua hoʻohana nui ʻia i nā uhi pale ahi intumescent. Hiki ke hoʻohui ʻia i ka mea kumu o nā uhi pale ahi e hana i kahi ʻōnaehana uhi pale ahi piha me nā mea pale ahi ʻē aʻe, nā mea hoʻopaʻa a me nā mea hoʻopiha. Ma keʻano laulā, ʻo ka hoʻopili ʻana o ka ammonium polyphosphate i nā uhi pale ahi intumescent hiki ke hāʻawi i nā ʻano pale ahi maikaʻi loa a me ka hoʻonui ʻana, a pale pono i ka palekana o nā hale a me nā hale i ke ahi.
Noi
Wahi a nā mea like ʻole e pono ai ma APP, ʻo ka hoʻohana ʻana o ka ammonium polyphosphate i ka uhi ʻana e hōʻike nui ʻia i loko o:
1. ʻO ka uhi FR Intumescent ma luna o ke kūkulu kila o loko.
2. Uhi hope lole i loko o nā pale, uhi blackout.
3. Uea FR.
4. Hoʻohana nui ʻia i ke kūkulu ʻana, ka mokulele, ka uhi ʻana i ka ʻili o nā moku.
ʻO ke ʻano hoʻohālike o ka uhi intumescent
