I-Ammonium polyphosphate, okubizwa ngokuthiAPP, i-phosphate equkethe i-nitrogen ebukeka njengempushana emhlophe. Ngokwezinga layo le-polymerization, ingahlukaniswa ngezinhlobo ezintathu: i-polymerization ephansi, i-polymerization ephakathi kanye ne-polymerization ephezulu. Uma izinga le-polymerization likhulu, kuncane ukuncibilika kwamanzi. I-Crystalline ammonium polyphosphate iyi-polyphosphate engancibiliki emanzini futhi enochungechunge olude. Kunezinhlobonhlobo ezinhlanu ukusuka ku-I kuye ku-V.

Izinga eliphakeme le-polymerization crystalline uhlobo lwe-II i-ammonium polyphosphate inezinzuzo ezibalulekile emkhakheni wezinto ze-polymer ngenxa yokungancibiliki kahle kwamanzi, izinga lokushisa eliphezulu lokubola, nokuhambisana okuhle nezinto ze-polymer. Uma kuqhathaniswa nezinqamuli zomlilo ezine-halogen, uhlobo lwecrystalline lwe-ammonium polyphosphate lunezici zobuthi obuphansi, intuthu ephansi, kanye ne-inorganic. Iwuhlobo olusha lwe-inorganic flame retardant esebenza kahle kakhulu.

Umlando wokuthuthukiswa kohlelo lokusebenza
Ngo-1857, i-ammonium polyphosphate yafundwa okokuqala.
Ngo-1961, yasetshenziswa njengomanyolo wokugxila okuphezulu.
Ngo-1969, ukusetshenziswa kobuchwepheshe obusha kwanweba ukusetshenziswa kwayo kuma-flame retardants.
Ngo-1970, i-United States yaqala ukukhiqiza i-flame retardant ammonium polyphosphate.
Ngo-1972, eJapane yaqala ukukhiqiza flame retardant ammonium polyphosphate.
Ngawo-1980, iShayina yafunda i-ammonium polyphosphate ene-flame retardant.

Amafayela ohlelo
I-Ammonium polyphosphate isetshenziswa kabanzi njenge-ejenti yokwelapha ebambezela ilangabi kumapulasitiki, irabha, nemicu;
Ingase futhi isetshenziselwe ukulungisa i-intumescent ye-retardant ye-retardant yokwelashwa komlilo wemikhumbi, izitimela, izintambo kanye nezakhiwo eziphakeme kakhulu, kanye nezinkuni ezivimbela umlilo kanye nephepha.
Ibuye isetshenziselwe ukukhiqiza izinto zokucima umlilo eziyimpuphu ezomile zokucima umlilo ezinkulu ezindaweni zamalahle, imithombo kawoyela kanye nasemahlathini;
Ngaphezu kwalokho, ingasetshenziswa futhi njengomanyolo.

Imakethe yomhlaba wonke
Ngokuthuthukiswa kwama-flame retardants omhlaba wonke ekuqondeni kwe-halogen-free, i-intumescent flame retardants esebenzisa i-ammonium polyphosphate njengempahla eluhlaza eyinhloko isiphenduke indawo eshisayo embonini, ikakhulukazi isidingo sohlobo lwe-II-ammonium polyphosphate enezinga eliphezulu le-polymerization.

Ngokusatshalaliswa kwesifunda, iNyakatho Melika, iNtshonalanga Yurophu, iJapan kanye nesifunda sase-Asia-Pacific (ngaphandle kweJapan) izimakethe ezine ezinkulu ze-ammonium polyphosphate. Isidingo se-ammonium polyphosphate emakethe yase-Asia-Pacific sikhule kakhulu futhi manje sesiyimakethe yabathengi enkulu kunazo zonke emhlabeni ye-ammonium polyphosphate, ebalelwa ku-55.0% ngo-2018.

Mayelana nokukhiqizwa, abakhiqizi be-APP bomhlaba wonke bagxile kakhulu eNyakatho Melika, eYurophu naseChina. Imikhiqizo eyinhloko ihlanganisa i-Clariant, i-ICL, i-Monsanto yase-USA (i-PhoschekP/30), i-Hoechst yaseJalimane (i-Exolit263), i-Montedison yase-Italy (i-SpinflamMF8), i-Sumitomo ne-Nissan yase-Japan, njll.
Engxenyeni ye-ammonium polyphosphate kanye ne-liquid fertilizer segment, i-ICL, i-Simplot, ne-PCS yizinkampani eziphambili, kanti ezinye ngamabhizinisi amancane naphakathi.
