Na Waiwai Kino a Kimia Hiki ke hoʻokaʻawale ʻia ka Ammonium polyphosphate i ʻekolu mau ʻano ma muli o kona degere o ka polymerization: polymer haʻahaʻa, polymer medium, a me ka polymer kiʻekiʻe. ʻO ke kiʻekiʻe o ka polymerization, ʻoi aku ka liʻiliʻi o ka wai. Wahi a kona ʻano, hiki ke hoʻokaʻawale ʻia i nā ʻano crystalline a me amorphous. ʻO Crystalline ammonium polyphosphate he wai hiki ʻole ke hoʻoheheʻe ʻia a he polyphosphate kaulahao lōʻihi. ʻElima mau ʻano like ʻole mai I a i V ʻano.
Hoʻohana Hoʻohana ʻia i ka hana ʻana i nā mea hoʻopaʻa ahi, nā plastics flame retardant a me nā huahana pale ahi, etc.
Hoʻohana nui ʻia ia i nā uhi pale ahi intumescent a me nā resins thermosetting (e like me ka polyurethane rigid foam, UP resin, epoxy resin, a me nā mea ʻē aʻe), a hiki ke hoʻohana ʻia no ka pale ahi o ka fiber, lāʻau a me nā huahana. No ka loaʻa ʻana o ke kaumaha molecular kiʻekiʻe o ka APP (n> 1000) a me ke kūpaʻa kiʻekiʻe, hiki ke hoʻohana ʻia ma ke ʻano he mea hana nui o ka thermoplastics flame retardant intumescent, ʻoi aku hoʻi ma PP a hiki i UL 94-Vo no ka hana ʻana i nā ʻāpana uila.

Hoʻolauna

ʻO ka Ammonium polyphosphate (PAAP no ka pōkole) he polymer inorganic me ka pale ahi a me nā waiwai pale ahi. ʻO kona ʻano molekala he mau polymers o ka phosphate a me ka ammonium ion.

 

Hoʻohana nui ʻia ka Ammonium polyphosphate i nā mea pale ahi, nā mea refractory a me nā uhi pale ahi. Hiki iā ia ke hoʻomaikaʻi maikaʻi i ka hana pale ahi o ka mea, hoʻopaneʻe i ke kaʻina puhi ahi, pale i ka laha ʻana o ke ahi, a hoʻemi i ka hoʻokuʻu ʻana i nā kinoea ʻino a me ka uahi.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana i ka ammonium polyphosphate e pili pinepine i ka hopena o ka waikawa phosphoric a me nā paʻakai ammonium. I ka wā o ka hopena, hoʻokumu ʻia nā paʻa kemika ma waena o ka phosphate a me nā ion ammonium, e hana ana i nā polymers me nā ʻāpana phosphate a me ka ammonium.

 

ʻIke palekana: He palekana ka Ammonium polyphosphate ma lalo o ka hoʻohana maʻamau a me nā kūlana mālama. Hōʻalo i ka hoʻohu ʻana i ka lepo ammonium polyphosphate no ka mea hiki ke hoʻopilikia i ka hanu. I ka lawelawe ʻana i ka ammonium polyphosphate, e hahai pono i nā kaʻina hana palekana kūpono a mālama pono a hoʻolei i ka pūhui.
