Te Tikanga Ārai Ahi me te Painga o te Ammonium Polyphosphate
E toru ngā momo o te aukati mura o te ammonium polyphosphate (APP) i runga i te nui o te polymerization: te polymerization iti, te polymerization waenga, me te polymerization teitei. Ko te teitei ake o te polymerization, ko te iti ake o te wairewatanga wai, me te ritenga kē. I roto i te hanganga, ka taea te wehewehe ki ngā āhua tioata me ngā āhua kore-ahua, ko te tioata APP he tote mekameka roa e kore e wairewatia ki te wai. Ko te tātai ngota whānui o te APP ko (NH₄)ₙ₊₂PₙO₃ₙ₊₁. Ina kei waenganui i te 10 ki te 20 te n, ka wairewatia ki te wai; ina neke atu te n i te 20, ka kore e wairewatia. Kāore he paitini o te APP, kāore he kakara, kāore e waikura, ā, he iti te hygroscopicity, he pumau wera teitei, ā, he pai te mahi hei aukati mura kore-halogen.
Tikanga Ārai Mura o te APP:
Ina wera, ka pirau te APP hei hanga waikawa poly-/metaphosphoric, e whakatairanga ana i te maroke me te waro i runga i te mata o ngā rauemi rauropi. Ka whānui ake i te wera, ka hanga he paparanga tiaki e wehe ana i te rauemi mai i te hāora, ā, ka tutuki ai te ātete mura. Hei tāpiri, ka tukuna e te pirau wera o te APP ngā hau kore-mura pērā i te CO₂ me te NH₃, e whakaiti ana i te kukū hāora i te rangi, ka tapahia atu te tuku hāora. Ko te hua o ēnei āhuatanga he iti te tukunga paowa, kāore he hau paitini e puta, me ngā āhuatanga tineia-ake. He mea nui, ko te kore o ngā hau paitini ehara i te mea he pai mō te taiao engari he mea nui hoki mō te haumaru o te ora—e whakaatu ana ngā tatauranga neke atu i te 80% o ngā matenga i roto i ngā aituā ahi nui i puta mai i ngā paowa paitini mai i te wera o ngā kirihou, ngā wāhanga hiko, me ētahi atu rauemi, kaua ko ngā mura tonu.
Kaihanga o te Ārai Mumura APP:
Ka whakamahia e te Taifeng Flame Retardant te hangarau microencapsulation maha-paparanga matatau o te ao hei whakaputa i te APP teitei-polymerization me te nui o te phosphorus me te hauota. He pai te pumau o te hua i te wera, he iti te wairewatanga wai, he tata-kore te pH, me te kaha teitei o te ātete mura. He paura totoka ma, kāore e waikura, kāore e mura, ā, he taumaha ngota teitei (n > 1200), he pumau, he ātete huarere. He whānuitia te whakamahinga i roto i ngā paninga ātete ahi e hangai ana ki te wai, ngā paninga kakahu, me te mea he wāhanga matua i roto i ngā thermoplastics ātete mura intumescent. Ka tukuna te hua kua kapi ki te maimoatanga mata hei whakapai ake i te hototahitanga, te ātete makuku, te pH kawakore, me te iti ake o te wairewatanga wai.
