Ammonium polyphosphate (APP)ndi imodzi mwazozimitsa moto zomwe zimagwiritsidwa ntchito kwambiri chifukwa champhamvu zake zoletsa moto.Amagwiritsidwa ntchito kwambiri m'machitidwe osiyanasiyana, mongankhuni, mapulasitiki, nsalu,ndizokutira.
Zomwe zimalepheretsa lawi la APP makamaka zimatheka chifukwa chakutha kwake kutulutsa mpweya wosayaka ukakhala ndi kutentha kapena moto.APP ikatenthedwa, imakhala ndi zovuta zowonongeka.Poyamba, ammonium polyphosphate dehydrates kupanga polyphosphoric acid ndi ammonia.
Komanso kuwonongeka kwa asidi polyphosphoric kumabweretsa mapangidwe asidi phosphoric, amene mtheradi lawi retardant product.Phosphoric asidi amphamvu asidi chothandizira, kuchititsa kuwonongeka kwa zipangizo kuyaka ndi kuletsa kuyaka ndondomeko.Imatha kuchitapo kanthu ndi zinthu zoyaka, monga ma hydrocarbon, kuti ipange zotsalira zamoto.Zotsalira zamotozi zimakhala ngati chitetezo chomwe chimalepheretsa kutuluka kwa mpweya woyaka komanso kuteteza kufalikira kwa moto.
Kuphatikiza apo, kukhalapo kwa phosphoric acid kumapangitsa kuti pakhale njira yolumikizira gawo.Njirayi imaphatikizapo kupanga malo otetezera, opangidwa ndi ammonium phosphates, pamwamba pa zinthuzo.Chosanjikizachi chimagwira ntchito ngati chotchinga chakuthupi, kuteteza zinthuzo ku kutentha ndi moto.Zimalepheretsa kuyenda kwa kutentha ndipo zimalepheretsa mpweya kufika pazinthuzo, ndikulepheretsa kuyaka.
Kuphatikiza pa zomwe zimawotcha moto, APP imagwiranso ntchito ngati chopondereza utsi.Kutuluka kwa mpweya wosayaka, monga ammonia ndi nthunzi wamadzi, kumachepetsa kuchuluka kwa mpweya woyaka mumlengalenga wozungulira.Kuchepetsa kuchuluka kwa gasi woyaka uku kumachepetsa chiopsezo choyatsira ndikuchepetsa kufalikira kwa moto.
Ammonium polyphosphate imakhala ndi mawonekedwe abwino kwambiri oletsa moto pamagwiritsidwe osiyanasiyana.Njira yake imaphatikizapo kutulutsa mpweya wosayaka, kupanga zotsalira zamoto, ndi kupanga chinsalu choteteza.Njirazi zimagwira ntchito limodzi kuti zichedwetse nthawi yoyatsira, kupondereza kuyaka, kuchepetsa kutulutsa utsi, ndikuletsa kufalikira kwa moto.
Mwachidule, ammonium polyphosphate (APP) imagwira ntchito ngati yoletsa moto chifukwa cha mphamvu yake yotulutsa mpweya wosayaka, kupanga chitetezero pamwamba pa zinthuzo, ndikulepheretsa kuyaka.Njira yake imatsimikizira chitetezo ndi chitetezo cha zipangizo zosiyanasiyana ku zoopsa za moto.
Malingaliro a kampani Shifang Taifeng New Flame Retardant Co., Ltdndi katswiri wa ammonium polyphospahte (APP) facotry ku China yemwe ali ndi zaka 22 zakubadwa.
