Ammonium polyphosphate (APP)ndeimwe yezvinodzivisa moto zvinoshandiswa zvakanyanya nekuda kwehunhu hwayo hwakanaka hwezvinodzivisa moto. Inoshandiswa zvakanyanya mumabasa akasiyana-siyana, akadai sehuni, mapurasitiki, machirauyemachira ekuputira.
Hunhu hweAPP hunodzora moto hunonyanya kukonzerwa nekukwanisa kwayo kuburitsa magasi asingabatike kana yaiswa pakupisa kana pamoto. Kana APP yapiswa, inoora zvakanyanya. Pakutanga, ammonium polyphosphate inodonha mvura kuti igadzire polyphosphoric acid uye ammonia.
Kuparara kwakawanda kwepolyphosphoric acid kunotungamira pakuumbwa kwephosphoric acid, inova ndiyo chigadzirwa chekupedzisira chinodzivirira moto. Phosphoric acid inoshanda sechinhu chakasimba chinokonzera acid, ichikonzera kuparara kwezvinhu zvinobvira uye ichidzivisa maitiro ekupisa. Inogona kuita zvinoenderana nezvinhu zvinobvira, zvakaita sehydrocarbons, kugadzira char residues. Char residues iyi inoshanda sechikamu chinodzivirira chinotadzisa kuburitswa kwemagasi anobvira uye inodzivirira kupararira kwemoto.
Uyezve, kuvapo kwephosphoric acid kunotungamira pakuumbwa kwechimiro chechikamu chakamanikana. Ichi chimiro chinosanganisira kuumbwa kwechikamu chinodzivirira, chine ammonium phosphates, pamusoro pechinhu chacho. Chikamu ichi chinoshanda sechidziviriro chemuviri, chinodzivirira chinhu kubva pakupisa nemurazvo. Chinodzivisa kufamba kwekupisa uye chinodzivirira okisijeni kusvika kune chinhu, zvichinyatsodzivisa maitiro ekupisa.
Pamusoro pesimba rayo rinodzivirira moto, APP inoshandawo semushonga unodzivisa utsi. Kuburitswa kwemagasi asingabatike, akadai seammonia neutsi hwemvura, kunoderedza huwandu hwemagasi anobatika mumhepo yakapoteredza. Kuderedzwa uku kwehuwandu hwegasi rinobatika kunoderedza njodzi yekubatidzwa uye kunonotsa kupararira kwemoto.
Ammonium polyphosphate ine hunhu hwakanaka hunodzivirira moto mumhando dzakasiyana-siyana dzekushandiswa. Maitiro ayo anosanganisira kuburitsa magasi asingabatike, kuumbwa kwezvimedu zvechar, uye kugadzirwa kwechikamu chinodzivirira. Maitiro aya anoshanda pamwe chete kunonotsa nguva yekubatidza, kudzvinyirira maitiro ekutsva, kuderedza kuburitswa kweutsi, uye kudzivirira kupararira kwemoto.
Muchidimbu, ammonium polyphosphate (APP) inoshanda sechinhu chinodzivirira moto nekuda kwekukwanisa kwayo kuburitsa magasi asingabatike, kugadzira jira rinodzivirira pamusoro pechinhu chacho, uye kudzivirira kupisa. Maitiro ayo anovimbisa kuchengetedzeka nekuchengetedzwa kwezvinhu zvakasiyana-siyana kubva panjodzi dzemoto.
