Pokulitsa ma sealant formulations, ammonium polyphosphate (APP) imagwira ntchito yofunika kwambiri pakukulitsa kukana moto.
APP imagwiritsidwa ntchito nthawi zambiri ngati cholepheretsa lawi pokulitsa mapangidwe azitsulo.Ikatenthedwa kwambiri pamoto, APP imakhala ndi kusintha kwakukulu kwamankhwala.Kutentha kumayambitsa kutulutsa kwa phosphoric acid, komwe kumayenderana ndi ma free radicals opangidwa ndi kuyaka.Izi mankhwala amachita amalimbikitsa mapangidwe wandiweyani Charl wosanjikiza.Char layer iyi imakhala ngati chotchinga chotchinga, chomwe chimalepheretsa kutentha ndi mpweya kupita kuzinthu zomwe zili pansi, motero zimalepheretsa kufalikira kwa malawi.
Kuphatikiza apo, APP imagwira ntchito ngati choletsa moto wamoto pakukulitsa zosindikizira.Akayatsidwa ndi moto, zowonjezera zowonjezera, kuphatikizapo APP, zimakhala ndi kutupa, kuphulika, ndikupanga wosanjikiza wotetezera.Chigawochi chimathandizira kuchepetsa kutentha kwa kutentha ndi kutulutsa mpweya wosayaka, motero kumachepetsa kufalikira kwa moto.
Kuphatikiza apo, kupezeka kwa APP pakukulitsa zosindikizira kumawonjezera kukana kwawo moto ndikukwaniritsa miyezo yolimba yachitetezo chamoto.Char yomwe idapangidwa chifukwa cha machitidwe a APP imateteza bwino zida zomwe zili pansi, kupereka nthawi yowonjezereka yoyankha mwadzidzidzi ndi kuthamangitsidwa pakayaka moto.
Pomaliza, pakukulitsa mapangidwe a sealant, kuphatikizika kwa ammonium polyphosphate kumathandizira kwambiri kukana moto mwa kulimbikitsa mapangidwe a chiwombankhanga choteteza, kuchepetsa kutentha ndi kutengera mpweya wa okosijeni, ndikupereka chotchinga chogwira ntchito motsutsana ndi kufalikira kwa malawi.Izi zimathandiza kuti chitetezo cha moto chikhale chokwanira komanso ntchito zowonjezera zowonjezera zosindikizira muzinthu zosiyanasiyana.
