ʻO ka ʻōnaehana pale ahi Ammonium Polyphosphate a me ka pono

Hiki ke hoʻokaʻawale ʻia ka mea pale ahi Ammonium polyphosphate (APP) i ʻekolu ʻano ma muli o kona kekelē o ka polymerization: haʻahaʻa, waena, a me ke kiʻekiʻe o ka polymerization. ʻO ke kiʻekiʻe o ke kekelē polymerization, ʻoi aku ka haʻahaʻa o ka solubility wai, a ʻo ka hope. Ma ke ʻano kūkulu, hiki ke hoʻokaʻawale ʻia i nā ʻano crystalline a me amorphous, me ka crystalline APP he paʻakai wai-hoʻoheheʻe ʻole lōʻihi. ʻO ke ʻano molekala maʻamau o APP ʻo (NH₄)ₙ₊₂PₙO₃ₙ₊₁. Ke pae ʻo n mai 10 a 20, hiki ke hoʻoheheʻe ʻia i ka wai; ke ʻoi aku ʻo n ma mua o 20, lilo ia i mea hiki ʻole ke hoʻoheheʻe ʻia. ʻAʻohe ʻawaʻawa o APP, ʻaʻohe ʻala, ʻaʻole e corrosive, a hōʻike i ka hygroscopicity haʻahaʻa, kūpaʻa wela kiʻekiʻe, a me ka hana maikaʻi loa ma ke ʻano he mea pale ahi halogen-free.

ʻAno hana pale lapalapa o ka APP:
Ke hoʻomehana ʻia, palaho ka APP e hana i ka poly-/metaphosphoric acid, kahi e hoʻoulu ai i ka dehydration a me ke carbonization ma luna o ka ʻili o nā mea organik. Hoʻonui ia i ka hoʻomehana ʻana, e hana ana i kahi papa pale e hoʻokaʻawale i ka mea mai ka oxygen, a laila e loaʻa ai ka pale ahi. Eia kekahi, hoʻokuʻu ka decomposition thermal o APP i nā kinoea ʻaʻole hiki ke puhi ʻia e like me CO₂ a me NH₃, kahi e hoʻoheheʻe ai i ka nui o ka oxygen i ka lewa, e ʻoki hou ana i ka lako oxygen. ʻO kēia mau ʻano ka hopena i ka hoʻokuʻu ʻana o ka uahi haʻahaʻa, ʻaʻohe hana kinoea ʻawahia, a me nā waiwai kinai ponoʻī. ʻO ka mea nui, ʻo ka nele o nā kinoea ʻawahia ʻaʻole wale ia he mea aloha i ke kaiapuni akā he mea koʻikoʻi hoʻi no ka palekana o ke ola—hōʻike nā helu helu ma mua o 80% o nā make i nā hanana ahi nui i hana ʻia e nā uahi ʻawahia mai nā plastics e puhi ana, nā ʻāpana uila, a me nā mea ʻē aʻe, ma mua o nā lapalapa ponoʻī.

Mea Hana o APP Flame Retardant:
Hoʻohana ʻo Taifeng Flame Retardant i ka ʻenehana microencapsulation multi-layer holomua honua e hana i ka APP polymerization-degree kiʻekiʻe me ka nui o ka phosphorus a me ka nitrogen. Loaʻa i ka huahana ke kūpaʻa wela maikaʻi loa, ka solubility wai haʻahaʻa, ka pH kokoke i ka neutral, a me ka pono flame-retardant kiʻekiʻe. He pauka keʻokeʻo paʻa, ʻaʻole hygroscopic, ʻaʻole hiki ke lapalapa, a hōʻike i ke kaumaha molekala kiʻekiʻe (n > 1200), kūpaʻa, a me ke kūpaʻa i ka wā. Hoʻohana nui ʻia ia i nā uhi pale ahi wai, nā uhi lole, a ma ke ʻano he mea nui i nā thermoplastics flame-retardant intumescent. Hoʻomaʻamaʻa ʻia ka huahana i hoʻopuni ʻia no ka hoʻomaikaʻi ʻana i ka hoʻohālikelike, hoʻonui i ke kūpaʻa makū, pH alkaline, a me ka solubility wai haʻahaʻa.
