Ammonium polyphosphate, nke a kpọrọAPP, bụ phosphate nwere nitrogen nke nwere ọdịdị ntụ ntụ ọcha. Dịka ọkwa polymerization ya si dị, enwere ike kewaa ya n'ụdị atọ: obere polymerization, ọkara polymerization na nnukwu polymerization. Ka ogo polymerization na-abawanye, otú ahụ ka mmiri na-agbaze obere. Crystalline ammonium polyphosphate bụ polyphosphate nke a na-anaghị agbaze na mmiri ma dị ogologo. E nwere ụdị ise site na I ruo V.

Oke ogo nke polymerization kristal nke ụdị II ammonium polyphosphate nwere uru dị ukwuu n'ọhịa nke ihe polymer n'ihi na ọ naghị agbaze nke ọma na mmiri, okpomọkụ ya dị elu, yana ezigbo ndakọrịta na ihe polymer. Ma e jiri ya tụnyere ihe ndị na-egbochi ọkụ nke nwere halogen, kristal nke ụdị II ammonium polyphosphate nwere njirimara nke obere nsí, obere anwụrụ ọkụ, na inorganic. Ọ bụ ụdị ọhụrụ nke inorganic na-egbochi ọkụ na-adịghị arụ ọrụ nke ọma.

Akụkọ mmepe ngwa
Na 1857, e bu ụzọ mụọ ammonium polyphosphate.
Na 1961, e ji ya mee fatịlaịza nwere ọtụtụ ihe dị mkpa.
Na 1969, ojiji nke teknụzụ ọhụrụ gbasaara ojiji ya na ihe ndị na-egbochi ire ọkụ.
Na 1970, mba Amerịka malitere imepụta ammonium polyphosphate nke na-egbochi ire ọkụ.
Na 1972, Japan malitere imepụta ammonium polyphosphate nke na-egbochi ire ọkụ.
N'afọ 1980, China mụrụ ihe gbasara ammonium polyphosphate nke na-egbochi ire ọkụ.

E tinyere akwụkwọ anamachọihe
A na-eji ammonium polyphosphate eme ihe dị ka ihe na-egbochi ire ọkụ maka plastik, roba, na eriri;
A pụkwara iji ya kwadebe ihe mkpuchi ihe mgbochi ọkụ na-egbuke egbuke maka ọgwụgwọ nchekwa ọkụ nke ụgbọ mmiri, ụgbọ okporo ígwè, eriri na ụlọ ndị dị elu, yana osisi na akwụkwọ na-egbochi ọkụ.
A na-ejikwa ya emepụta ihe ndị na-eme ka ọkụ gbanyụọ ntụ ntụ kpọrọ nkụ maka nnukwu ọkụ na-agba n'ọhịa kol, olulu mmanụ na oke ọhịa;
Tinyere nke ahụ, enwere ike iji ya dị ka fatịlaịza.

Ahịa zuru ụwa ọnụ
Site na mmepe nke ihe ndị na-egbochi ire ọkụ zuru ụwa ọnụ n'akụkụ nke enweghị halogen, ihe ndị na-egbochi ire ọkụ intumescent na-eji ammonium polyphosphate dị ka ihe bụ isi ihe eji emepụta ihe aghọwo ebe a na-ewu ewu n'ụlọ ọrụ ahụ, karịsịa ọchịchọ maka ụdị II-ammonium polyphosphate nwere nnukwu polymerization.

Maka nkesa mpaghara, North America, Western Europe, Japan na mpaghara Asia-Pacific (ewezuga Japan) bụ ahịa anọ kachasị mkpa maka ammonium polyphosphate. Ọchịchọ maka ammonium polyphosphate na ahịa Asia-Pacific amụbaala nke ukwuu ma ugbu a aghọọla ahịa ndị ahịa kachasị ukwuu n'ụwa maka ammonium polyphosphate, nke ruru 55.0% na 2018.

Maka mmepụta, ndị na-emepụta APP zuru ụwa ọnụ na-elekwasị anya na North America, Europe na China. Ndị isi ụlọ ọrụ gụnyere Clariant, ICL, Monsanto si USA (PhoschekP/30), Hoechst si Germany (Exolit263), Montedison si Italy (SpinflammMF8), Sumitomo na Nissan si Japan, wdg.
N'ime ngalaba fatịlaịza ammonium polyphosphate na mmiri mmiri, ICL, Simplot, na PCS bụ ụlọ ọrụ ndị bụ isi, ndị ọzọ bụkwa obere na ọkara ụlọ ọrụ.
