Ammonium polyphosphate (APP) bụ ihe mejupụtara inorganic nke a na-ejikarị eme ihe nke ukwuu, nke a maara nke ọma maka ọrụ ya dị ka ihe na-egbochi ire ọkụ na fatịlaịza. Ihe pụrụ iche ya na-eme ka ọ bụrụ ihe dị mkpa n'ọtụtụ ọrụ, gụnyere plastik, ákwà, na mkpuchi. Ịghọta nkwụsi ike okpomọkụ nke ammonium polyphosphate dị oke mkpa maka ojiji ya nke ọma, karịsịa na gburugburu ebe okpomọkụ dị elu.
Mmebi nke ammonium polyphosphate na-amalitekarị n'oge okpomọkụ dị elu, nke na-abụkarị ihe dị ka ogo 200 ruo 300 Celsius (ogo 392 ruo 572 Fahrenheit). N'oge okpomọkụ ndị a, ihe mejupụtara ya na-agbanwe usoro kemịkalụ nke nwere ike ibute ntọhapụ nke ammonia na phosphoric acid. Ka okpomọkụ na-abawanye elu, karịsịa karịa ogo 300 Celsius, usoro mmebi ahụ na-agba ọsọ, na-ebute mmebi nke usoro polymeric nke APP.
Enwere ike imetụta mmebi okpomọkụ nke ammonium polyphosphate site na ọtụtụ ihe, gụnyere ibu molekul ya, ọnụnọ nke ihe mgbakwunye, na usoro akọwapụtara ejiri. Dịka ọmụmaatụ, obere ibu molekul APP na-adịkarị ala na okpomọkụ dị ala ma e jiri ya tụnyere ụdị ibu molekul dị elu. Na mgbakwunye, ọnụnọ nke ihe ndị ọzọ na usoro mejupụtara nwere ike ime ka usoro mmebi ahụ ka mma ma ọ bụ gbochie ya, dabere na njirimara okpomọkụ ha na mmekọrịta ha na APP.
Otu n'ime ihe dị mkpa gbasara omume okpomọkụ nke ammonium polyphosphate bụ ọrụ ya dị ka ihe na-egbochi ire ọkụ. Mgbe a na-ekpughe ya na okpomọkụ, APP nwere ike iwepụta gas ndị na-anaghị ere ọkụ, nke na-ebelata uzuoku ndị na-ere ọkụ ma na-enyere aka igbochi ire ọkụ. Ihe onwunwe a bara uru karịsịa n'ọrụ ebe nchekwa ọkụ bụ ihe na-echegbu onwe ya. Agbanyeghị, irè nke APP dị ka ihe na-egbochi ire ọkụ nwere njikọ chiri anya na nkwụsi ike okpomọkụ ya. Ọ bụrụ na APP emebie ngwa ngwa, ọ nwere ike ọ gaghị enye ọkwa nchebe achọrọ.
Ọzọkwa, ngwaahịa mmebi nke ammonium polyphosphate nwekwara ike inwe mmetụta maka gburugburu ebe obibi na ahụike mmadụ. Dịka ọmụmaatụ, mwepụta nke ammonia nwere ike itinye aka na mmetọ ikuku ma nwee ike ibute ihe egwu ahụike ma ọ bụrụ na e kuo ya n'ọtụtụ buru ibu. Ya mere, ịghọta okpomọkụ mmebi na mwepụta gas na-esote dị mkpa maka inyocha nchekwa na mmetụta gburugburu ebe obibi nke ngwaahịa nwere APP.
N'ọrụ bara uru, ọ dị oke mkpa ịtụle ọnọdụ ọrụ na ike nke mmebi okpomọkụ mgbe ejiri ammonium polyphosphate. Ndị nrụpụta na-eme nyocha okpomọkụ, dịka nyocha thermogravimetric (TGA), iji chọpụta okpomọkụ mmebi kpọmkwem na iji melite usoro maka nkwụsi ike na arụmọrụ.
Na mmechi, ammonium polyphosphate na-amalite ịda n'ọnọdụ okpomọkụ dị ihe dị ka ogo 200 ruo 300 Celsius, ebe mbibi dị ukwuu na-eme na okpomọkụ dị elu. Nkwụsi ike okpomọkụ ya bụ ihe dị oke mkpa n'ịdị irè ya dị ka ihe na-egbochi ire ọkụ na uru ya n'ọtụtụ ngwa dị iche iche. Ịghọta ihe ndị a na-eme na okpomọkụ anaghị enyere aka na mmepe nke ngwaahịa dị nchebe ma dị irè karị kamakwa ọ na-eme ka e nwee nrubeisi na iwu gburugburu ebe obibi na ahụike. Ka nnyocha na-aga n'ihu, nghọta ndị ọzọ gbasara omume okpomọkụ nke ammonium polyphosphate ga-eme ka ngwa ya na profaịlụ nchekwa ya ka mma na ụlọ ọrụ.
