Ammonium polyphosphate (APP) chinhu chinoshandiswa zvakanyanya muzvidzimisi zvemoto uye zvinodzima moto. Fomura yayo yemakemikari ndeye (NH4PO3)n, apo n inomiririra mwero wepolymerization. Kushandiswa kweAPP muzvidzimisi zvemoto kunonyanya kuenderana nehunyanzvi hwayo hwakanaka hwekudzivirira moto uye kudzvinyirira utsi.
Chekutanga, basa guru reAPP muzvidzimisi zvemoto nderekudzivirira moto. Inodzivirira kupararira kwemoto uye maitiro ekutsva kuburikidza nenzira dzakasiyana-siyana. APP inoora pakupisa kwakanyanya kuti ibudise phosphoric acid neammonia. Phosphoric acid inogadzira firimu rekudzivirira rakaita segirazi pamusoro pemoto, ichiparadzanisa okisijeni nekupisa, nokudaro ichidzivirira kuenderera mberi kwekutsva. Amoniya inobatsira kuderedza gasi rinobvira munzvimbo yekutsva uye kuderedza kupisa kwemoto.
Chechipiri, APP ine hunhu hwakanaka hwekudzora utsi. Mumoto, utsi haungoderedzi kuona chete uye hunowedzera kuoma kwekubuda, asiwo hune huwandu hwakawanda hwemagasi ane chepfu, zvichikonzera njodzi huru kuhutano hwevanhu. APP inogona kuderedza kugadzirwa kweutsi panguva yekutsva uye kuderedza kukuvadza kwemoto.
Ammonium polyphosphate inoshandiswa muzvidzimisi zvemoto mumhando dzakasiyana-siyana, zvinonyanya kushandiswa muzvidzimisi zvemoto zvine hupfu hwakaoma uye zvidzimisi zvemoto zvine furo. Muzvidzimisi zvemoto zvine hupfu hwakaoma, ammonium polyphosphate ndeimwe yezvinhu zvikuru uye inosanganiswa nemamwe makemikari kuti igadzire hupfu hwakaoma hunodzima moto hunoshanda. Hupfu uhwu hunogona kufukidza zvinhu zvinotsva nekukurumidza, kuparadzanisa okisijeni, uye kudzima moto nekukurumidza. Muzvidzimisi zvemoto zvine furo, ammonium polyphosphate inosanganiswa nechinofumisa furo kuti igadzire furo rakagadzikana rinofukidza pamusoro pechinhu chinotsva, zvichiita basa rekutonhodza nekuparadzanisa okisijeni.
Pamusoro pezvo, ammonium polyphosphate inewo zvakanakira zvekuchengetedza nharaunda uye ine chepfu shoma. Kana ichienzaniswa nezvinodzora moto zvechinyakare zvine halogenated, ammonium polyphosphate haiburitse halides inokuvadza panguva yekutsva, zvichideredza kukuvadzwa kwenharaunda nemuviri wemunhu. Saka, kushandiswa kweammonium polyphosphate muzvidzimisi zvemoto zvemazuva ano kwave kuchiwedzera kutariswa.
Kazhinji, kushandiswa kweammonium polyphosphate muzvidzimisi zvemoto kune zvakanakira zvakawanda, zvinosanganisira kushanda zvakanaka kwekudzivirira moto, simba rakanaka rekudzora utsi, uye kuchengetedzwa kwezvakatipoteredza uye chepfu shoma. Nekufambira mberi kwesainzi netekinoroji uye kuvandudzwa kwezvinodiwa nevanhu zvekuchengetedza nekuchengetedza nharaunda, mikana yekushandiswa kweammonium polyphosphate muzvidzimisi zvemoto ichave yakakura.
