Njirimara anụ ahụ na kemịkalụ	Enwere ike kewaa ammonium polyphosphate n'ime ụdị atọ dabere na ogo polymerization ya: obere polymer, polymer polymer, na nnukwu polymer. Ọganihu nke polymerization dị elu, obere mmiri solubility dị ntakịrị. Dị ka usoro ya si dị, enwere ike kewaa ya n'ime ụdị kristal na amorphous. Crystalline ammonium polyphosphate bụ mmiri na-adịghị edozi na ogologo yinye polyphosphate. Enwere ọdịiche ise site na ụdị I ruo V.

Ammonium polyphosphate (PAAP maka mkpụmkpụ) bụ polymer inorganic nwere ihe na-egbochi ire ọkụ yana ihe na-egbochi ọkụ. Ọdịdị ya mejupụtara polymers nke phosphate na ammonium ion.

A na-eji ammonium polyphosphate eme ihe n'ọtụtụ ebe na ihe ndị na-ere ọkụ, ihe ndị na-emegharị ihe na ihe mkpuchi ọkụ. Ọ nwere ike imeziwanye arụmọrụ ọkụ na-ere ọkụ nke ihe ahụ nke ọma, na-egbu oge usoro combustion, gbochie mgbasa ọkụ, ma belata ntọhapụ nke gas na anwụrụ ọkụ.

Usoro nke ịkwadebe ammonium polyphosphate na-agụnye mmeghachi omume nke phosphoric acid na ammonium salts. N'oge mmeghachi omume ahụ, a na-emepụta njikọ kemịkalụ n'etiti phosphate na ammonium ion, na-eme polymers nwere otutu phosphate na ammonium ion nkeji.

Ozi nchekwa: Ammonium polyphosphate adịghị mma n'okpuru ojiji nkịtị yana ọnọdụ nchekwa. Zere ikuru uzuzu ammonium polyphosphate n'ihi na ọ nwere ike ịkpata nsogbu iku ume. Mgbe ị na-eji ammonium polyphosphate eme ihe, soro usoro ọrụ nchekwa dị mkpa ma chekwaa ma tụfuo ogige ahụ nke ọma.
