Ammonium polyphosphate (APP)ndi imodzi mwa zinthu zoletsa moto zomwe zimagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zake zabwino zoletsa moto. Imagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana, mongamatabwa, mapulasitiki, nsalundizokutira.
Mphamvu yoletsa moto ya APP makamaka imachokera ku mphamvu yake yotulutsa mpweya wosayaka ikakumana ndi kutentha kapena moto. APP ikatenthedwa, imawonongeka movutikira. Poyamba, ammonium polyphosphate imauma kuti ipange polyphosphoric acid ndi ammonia.
Kuwola kwina kwa polyphosphoric acid kumabweretsa kupangika kwa phosphoric acid, yomwe ndi chinthu choletsa moto kwambiri. Phosphoric acid imagwira ntchito ngati chothandizira champhamvu cha asidi, zomwe zimapangitsa kuti zinthu zomwe zimayaka ziwonongeke ndikuletsa kuyaka. Imatha kuchitapo kanthu ndi zinthu zomwe zimayaka, monga ma hydrocarbon, kuti ipange zotsalira za char. Zotsalira za char izi zimagwira ntchito ngati gawo loteteza lomwe limalepheretsa kutulutsa mpweya woyaka ndikuletsa kufalikira kwa moto.
Kuphatikiza apo, kukhalapo kwa phosphoric acid kumabweretsa kupangika kwa njira yolumikizirana. Njirayi imaphatikizapo kupangika kwa gawo loteteza, lopangidwa ndi ammonium phosphates, pamwamba pa chinthucho. Gawoli limagwira ntchito ngati chotchinga chakuthupi, choteteza chinthucho ku kutentha ndi malawi. Limalepheretsa kuyenda kwa kutentha ndipo limaletsa mpweya kufika pa chinthucho, ndikuletsa bwino kuyaka.
Kuwonjezera pa mphamvu zake zoletsa moto, APP imagwiranso ntchito ngati choletsa utsi. Kutulutsidwa kwa mpweya wosayaka, monga ammonia ndi nthunzi ya madzi, kumachepetsa kuchuluka kwa mpweya woyaka mumlengalenga wozungulira. Kuchepa kwa kuchuluka kwa mpweya woyaka kumeneku kumachepetsa chiopsezo cha kuyaka ndikuchepetsa kufalikira kwa moto.
Ammonium polyphosphate ili ndi mphamvu zabwino kwambiri zoletsa moto m'njira zosiyanasiyana. Njira yake imaphatikizapo kutulutsa mpweya wosayaka, kupanga zotsalira za char, komanso kupanga gawo loteteza. Njirazi zimagwira ntchito limodzi kuti zichedwetse nthawi yoyatsira moto, kuletsa kuyaka, kuchepetsa kupanga utsi, komanso kupewa kufalikira kwa moto.
Mwachidule, ammonium polyphosphate (APP) imagwira ntchito ngati choletsa moto chogwira ntchito bwino chifukwa cha mphamvu yake yotulutsa mpweya wosayaka, kupanga gawo loteteza pamwamba pa chinthucho, ndikuletsa kuyaka. Njira yake imaonetsetsa kuti zinthu zosiyanasiyana zitetezedwa ku zoopsa za moto.
Malingaliro a kampani Shifang Taifeng New Flame Retardant Co., Ltdndi fakitale yaukadaulo ya ammonium polyphosphate (APP) ku China yokhala ndi zaka 22 zogwira ntchito.
