Ammonium polyphosphate, zoro aka dị kaAPP, bụ phosphate nwere nitrogen nwere ọdịdị ntụ ntụ ọcha. Dị ka ogo nke polymerization si dị, enwere ike kewaa ya n'ime ụdị atọ: obere polymerization, ọkara polymerization na nnukwu polymerization. Ka ogo nke polymerization dị ukwuu, otú ahụ ka mmiri na-esiwanye ike. Crystalline ammonium polyphosphate bụ mmiri na-adịghị edozi na ogologo yinye polyphosphate. Enwere ọdịiche ise site na I ruo V.

Ụdị dị elu nke polymerization crystalline ụdị II ammonium polyphosphate nwere uru dị ịrịba ama n'ọhịa nke ihe ndị polymer n'ihi na mmiri dị mma na-adịghị edozi ya, okpomọkụ dị elu nke decomposition, na ezigbo ndakọrịta na ihe polymer. Tụnyere ihe ndị na-egbochi ire ọkụ nwere halogen, ụdị kristal II ammonium polyphosphate nwere njirimara nke nsi dị ala, obere anwụrụ ọkụ, na inorganic. Ọ bụ ụdị ọhụrụ nke nrụpụta ọkụ inorganic dị elu nke na-egbochi ire ọkụ.

Akụkọ mmepe ngwa
Na 1857, a na-amụ ammonium polyphosphate nke mbụ.
N'afọ 1961, a na-eji ya mee ihe dị ka fatịlaịza na-etinye uche dị elu.
N'afọ 1969, ntinye nke teknụzụ ọhụrụ gbasaara ngwa ya na ndị na-ere ọkụ.
N'afọ 1970, United States malitere imepụta ammonium polyphosphate na-ere ọkụ.
Na 1972, Japan malitere imepụta ammonium polyphosphate na-ere ọkụ.
N'afọ ndị 1980, China mụrụ ammonium polyphosphate na-ere ọkụ.

Ngwa gbara akwụkwọ
A na-eji ammonium polyphosphate eme ihe n'ọtụtụ ebe dị ka onye na-ahụ maka ọgwụgwọ ọkụ maka plastik, roba, na eriri;
A pụkwara iji ya kwadebe mkpuchi mkpuchi ọkụ intumescent maka ọgwụgwọ ọkụ ọkụ nke ụgbọ mmiri, ụgbọ oloko, eriri na ụlọ elu dị elu, yana ọkụ na-ekpuchi ọkụ na akwụkwọ.
A na-ejikwa ya na-emepụta ihe ọkụ ọkụ na-ekpo ọkụ na-ekpo ọkụ maka nnukwu ọkụ na-ekpochapụ n'ubi coal, olulu mmanụ na ọhịa;
Tụkwasị na nke ahụ, a pụkwara iji ya mee ihe dị ka fatịlaịza.

Ahịa zuru ụwa ọnụ
Site na mmepe nke ọkụ ọkụ zuru ụwa ọnụ n'ụzọ nke halogen-free, intumescent ọkụ retardants na-eji ammonium polyphosphate dị ka isi akụrụngwa aghọwo ebe na-ekpo ọkụ na ụlọ ọrụ, karịsịa na-achọ ụdị II-ammonium polyphosphate na elu ogo nke polymerization.

N'ihe gbasara nkesa mpaghara, North America, Western Europe, Japan na Asia-Pacific mpaghara (ewezuga Japan) bụ isi ahịa anọ maka ammonium polyphosphate. Ọchịchọ maka ammonium polyphosphate n'ahịa Eshia-Pacific etoola nke ukwuu ma bụrụkwa ahịa ahịa ahịa kacha ukwuu n'ụwa maka ammonium polyphosphate, na-aza 55.0% na 2018.

N'ihe gbasara mmepụta, ndị na-emepụta APP zuru ụwa ọnụ na-elekwasị anya na North America, Europe na China. Ndị isi ụdị gụnyere Clariant, ICL, Monsanto si USA (PhoschekP/30), Hoechst si Germany (Exolit263), Montedison si Italy (SpinflamMF8), Sumitomo na Nissan si Japan, wdg.
N'ime ammonium polyphosphate na mmiri mmiri fatịlaịza, ICL, Simplot, na PCS bụ ụlọ ọrụ ndị bụ isi, ndị ọzọ bụ obere ụlọ ọrụ dị obere na ọkara.
