Pakukulitsa njira zotsekera, ammonium polyphosphate (APP) imagwira ntchito yofunika kwambiri pakulimbitsa kukana moto.
APP imagwiritsidwa ntchito kwambiri ngati choletsa moto pokulitsa ma sealant. Ikatenthedwa kwambiri pamoto, APP imasinthidwa ndi mankhwala ovuta. Kutenthako kumayambitsa kutulutsidwa kwa phosphoric acid, yomwe imagwirizana ndi ma free radicals omwe amapangidwa ndi kuyaka. Kuchita kwa mankhwala kumeneku kumalimbikitsa kupangidwa kwa char layer yolimba. Char layer iyi imagwira ntchito ngati chotchinga choteteza, zomwe zimachepetsa kusamutsa kutentha ndi mpweya kuzinthu zomwe zili pansi pake, motero zimalepheretsa kufalikira kwa malawi.
Kuphatikiza apo, APP imagwira ntchito ngati choletsa moto chotuluka m'thupi pokulitsa ma sealant. Zikawotchedwa, zowonjezera zotuluka m'thupi, kuphatikizapo APP, zimatupa, zimayaka, ndipo zimakhala ngati choteteza kutentha. Chotsalirachi chimathandiza kuchepetsa kutentha komanso kutulutsa mpweya wosayaka, motero zimachedwetsa kufalikira kwa moto.
Kuphatikiza apo, kupezeka kwa APP mu zotsekera zomwe zikukula kumawonjezera kukana kwawo moto ndipo kumakwaniritsa miyezo yokhwima yotetezera moto. Kutentha komwe kumachitika chifukwa cha APP kumateteza bwino zinthu zomwe zili pansi pake, zomwe zimapatsa nthawi yowonjezera yoti zichitike mwadzidzidzi komanso kuti zituluke pakagwa moto.
Pomaliza, pakukulitsa mapangidwe a sealant, kuphatikiza kwa ammonium polyphosphate kumawonjezera kwambiri kukana moto mwa kulimbikitsa mapangidwe a char yoteteza, kuchepetsa kutentha ndi kusamutsa mpweya, komanso kupereka chotchinga chothandiza kufalikira kwa malawi. Izi zimathandiza kuti moto ukhale wotetezeka komanso magwiridwe antchito a zinthu zokulitsa sealant m'njira zosiyanasiyana.
