Ammonium polyphosphate (APP) inorganic compound inoshandiswa zvakanyanya mumoto retardants uye zvinodzima moto. Yayo kemikari formula ndeye (NH4PO3) n, apo n inomiririra dhigirii repolymerization. Iko kushandiswa kwe APP muzvidzimisa moto kunonyanya kuenderana neakanakisa kudzoreredza murazvo uye utsi hwekudzvinyirira zvivakwa.
Chekutanga, basa guru reAPP mune zvekudzimisa moto rakaita semurazvo wemoto. Inodzivisa kupararira kwemoto uye nzira yekupisa kuburikidza nemhando dzakasiyana-siyana. APP inoora pakupisa kwakanyanya kugadzira phosphoric acid uye ammonia. Phosphoric acid inoumba girazi rinodzivirira firimu panzvimbo inopisa, inoparadzanisa okisijeni uye kupisa, nokudaro kudzivirira kuenderera kwekupisa. Ammonia inobatsira kuderedza gasi rinopisa munzvimbo inopisa uye kuderedza kupisa kwemurazvo.
Chechipiri, APP ine yakanaka yekubvisa utsi zvivakwa. Mumoto, utsi haungodzikisi kuonekwa uye kunowedzera kuoma kwekupukunyuka, asiwo kune huwandu hwakawanda hwemagasi ane chepfu, zvichiita kutyisidzira kwakakomba kuhutano hwevanhu. APP inogona kunyatso kudzikisa chizvarwa cheutsi panguva yekupisa uye kuderedza kukuvadza kwemoto.
Ammonium polyphosphate inoshandiswa muzvokudzimisa moto nenzira dzakasiyana-siyana, iyo yakawanda kwazvo iyo inodzima moto yakaoma yehupfu uye yekudzimisa moto. Muzvinodzimisa moto zvehupfu hwakaoma, ammonium polyphosphate chimwe chezvinhu zvikuru zvinogadzirwa uye chinosanganiswa nemamwe makemikari kuita moto unoshanda unodzima upfu hwakaoma. Iyi poda yakaoma inogona kukurumidza kuvhara zvinhu zvinopisa, kubvisa okisijeni, uye nekukasira kudzima murazvo. Mumafuro emoto ekudzimisa moto, ammonium polyphosphate inosanganiswa neanoita furo kuti iite furo rakagadzikana rinovhara pamusoro pechinhu chinopisa, chichiita basa mukutonhodza uye kuparadzanisa okisijeni.
Mukuwedzera, ammonium polyphosphate zvakare ine zvakanakira kuchengetedza kwezvakatipoteredza uye yakaderera chepfu. Kana ichienzaniswa neyekare halogenated flame retardants, ammonium polyphosphate haiburitse halides inokuvadza panguva yekupisa, ichideredza kukuvadza kune zvakatipoteredza uye muviri wemunhu. Nokudaro, kushandiswa kweammonium polyphosphate mune zvekudzimisa moto kwemazuva ano kwakagamuchira kutariswa kwakawanda.
Kazhinji, kushandiswa kweammonium polyphosphate muzvokudzimisa moto kune zvakawanda zvakanakira, zvinosanganisira kushanda zvakanaka kwemurazvo wemoto, kunaka kwehutsi hwehutsi, uye kuchengetedza kwezvakatipoteredza uye kushomeka kwehuturu. Nekufambira mberi kwesainzi uye tekinoroji uye kuvandudzwa kwezvinodiwa zvevanhu zvekuchengetedza uye kuchengetedza kwezvakatipoteredza, tarisiro yekushandiswa kweammonium polyphosphate muzvidzimisa moto ichave yakakura.
