Ammonium polyphosphate, kunonziAPP, iphosphate ine nitrogen ine hupfu huchena hunoonekwa. Zvinoenderana nedhigirii rayo repolymerization, inogona kukamurwa kuita mhando nhatu: yakaderera polymerization, yepakati polymerization uye yakakwirira polymerization. Iyo yakakura dhigirii yepolymerization, iyo idiki yekunyungudika kwemvura. Crystalline ammonium polyphosphate is water-insoluble uye refu-cheni polyphosphate. Pane misiyano mishanu kubva kuI kusvika kuV.

High degree yepolymerization crystalline type II ammonium polyphosphate ine mabhenefiti akakosha mumunda wezvinhu zvepolymer nekuda kwekusanyungudika kwayo kwemvura, tembiricha yekuora yakanyanya, uye kuenderana zvakanaka nezvinhu zvepolymer. Kuenzaniswa nehalogen-ine murazvo retardants, crystalline type II ammonium polyphosphate ine hunhu hwekuderera muchetura, hutsi hushoma, uye inorganic. Irwo rudzi rutsva rwepamusoro-kushanda inorganic flame retardant.

Nhoroondo yekuvandudza kwekushandisa
Muna 1857, ammonium polyphosphate yakatanga kudzidzwa.
Muna 1961, yakashandiswa sefotereza yepamusoro.
Muna 1969, kushandiswa kwetekinoroji nyowani kwakawedzera kushanda kwayo kune zvinodzosa moto.
Muna 1970, United States yakatanga kugadzira murazvo unodzosera ammonium polyphosphate.
Muna 1972, Japan yakatanga kugadzira flame retardant ammonium polyphosphate.
Mumakore ekuma1980, China yakadzidza moto unodzoreredza ammonium polyphosphate.

Application mafaira
Ammonium polyphosphate inoshandiswa zvakanyanya semurazvo unodzoreredza kurapwa mumiriri wemapurasitiki, rabha, uye fiber;
Inogonawo kushandiswa kugadzirira intumescent fire retardant coatings yekudzivirira moto kurapwa kwezvikepe, zvitima, tambo uye zvivako zvepamusoro-soro, pamwe chete nehuni dzinopisa moto uye mapepa.
Inoshandiswawo kugadzira poda yakaoma yekudzima moto inodzima moto yakakura-yakakura muminda yemarasha, matsime emafuta uye masango;
Mukuwedzera, inogonawo kushandiswa sefetireza.

Global market
Nekuvandudzwa kwezvinodzoreredza murazvo wepasi rose mugwara rehalogen-isina, intumescent flame retardants uchishandisa ammonium polyphosphate seyakanyanya mbishi yave nzvimbo inopisa muindasitiri, kunyanya kudiwa kwemhando II-ammonium polyphosphate ine dhigirii repolymerization.

Panyaya yekugoverwa kwedunhu, North America, Western Europe, Japan neAsia-Pacific dunhu (kunze kweJapan) ndiyo misika mina mikuru yeammonium polyphosphate. Iko kudiwa kweammonium polyphosphate mumusika weAsia-Pacific kwakura zvakanyanya uye yave musika mukuru wevatengi pasi rose weammonium polyphosphate, inoverengera 55.0% muna 2018.

Panyaya yekugadzirwa, vagadziri vepasi rose APP vanonyanya kutariswa muNorth America, Europe neChina. Mhando huru dzinosanganisira Clariant, ICL, Monsanto kubva kuUSA (PhoschekP/30), Hoechst kubva kuGermany (Exolit263), Montedison kubva kuItari (SpinflamMF8), Sumitomo neNissan kubva kuJapan, nezvimwe.
Muchikamu cheammonium polyphosphate uye fetiraiza yemvura, ICL, Simplot, uye PCS ndiwo makambani makuru, uye mamwe mabhizinesi madiki uye epakati.
