Ammonium polyphosphate (APP) yog ib qho inorganic compound dav siv hauv cov nplaim hluav taws thiab tua hluav taws. Nws cov tshuaj formula yog (NH4PO3)n, qhov twg n sawv cev rau qib ntawm polymerization. Daim ntawv thov ntawm APP nyob rau hauv cov hluav taws tua hluav taws yog tsuas yog raws li nws cov nplaim taws retardant zoo heev thiab cov pa taws tua hluav taws.
Ua ntej, lub luag haujlwm tseem ceeb ntawm APP hauv cov hluav taws tua hluav taws yog cov nplaim hluav taws. Nws inhibits kev sib kis ntawm cov nplaim taws thiab cov txheej txheem combustion los ntawm ntau yam txheej txheem. APP decomposes ntawm qhov kub thiab txias los tsim phosphoric acid thiab ammonia. Phosphoric acid tsim cov iav tiv thaiv zaj duab xis ntawm qhov chaw combustion, cais cov pa oxygen thiab cua sov, yog li tiv thaiv kev txuas ntxiv ntawm combustion. Ammonia pab dilute cov roj combustible nyob rau hauv combustion cheeb tsam thiab txo qhov kub ntawm cov nplaim taws.
Qhov thib ob, APP muaj cov pa luam yeeb zoo. Hauv qhov hluav taws kub, cov pa luam yeeb tsis yog tsuas yog txo qhov pom thiab ua rau muaj kev nyuaj ntawm kev khiav, tab sis kuj muaj cov pa roj ntau ntau, ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv. APP tuaj yeem txo qhov tsim ntawm cov pa luam yeeb thaum lub sij hawm combustion txheej txheem thiab txo qhov teeb meem ntawm hluav taws.
Ammonium polyphosphate yog siv nyob rau hauv cov hluav taws tua hluav taws nyob rau hauv ntau yam ntaub ntawv, feem ntau yog cov qhuav hmoov hluav taws tua hluav taws thiab ua npuas ncauj extinguishers. Hauv cov hmoov qhuav hluav taws tua hluav taws, ammonium polyphosphate yog ib qho ntawm cov khoom xyaw tseem ceeb thiab sib xyaw nrog lwm cov tshuaj los ua kom muaj hluav taws tua hluav taws kom zoo. Cov hmoov qhuav no tuaj yeem npog cov khoom siv hluav taws xob sai, cais cov pa oxygen, thiab tua hluav taws sai sai. Hauv cov hluav taws kub hnyiab, ammonium polyphosphate yog tov nrog ib tug foaming tus neeg sawv cev los tsim ib tug ruaj khov ua npuas ncauj uas npog cov nplaim ntawm cov khoom siv hluav taws kub, ua lub luag haujlwm hauv kev ua kom txias thiab cais cov pa oxygen.
Tsis tas li ntawd, ammonium polyphosphate kuj muaj qhov zoo ntawm kev tiv thaiv ib puag ncig thiab tsis muaj tshuaj lom. Piv nrog rau cov tsoos halogenated nplaim retardants, ammonium polyphosphate tsis tso cov teeb meem halides thaum combustion, txo cov kev puas tsuaj rau ib puag ncig thiab tib neeg lub cev. Yog li ntawd, daim ntawv thov ntawm ammonium polyphosphate nyob rau hauv niaj hnub tua hluav taws tau txais ntau thiab ntau xim.
Feem ntau, daim ntawv thov ntawm ammonium polyphosphate hauv cov hluav taws tua hluav taws muaj ntau yam zoo, nrog rau kev ua tau zoo ntawm cov nplaim hluav taws, kev ua kom muaj pa taws zoo, thiab kev tiv thaiv ib puag ncig thiab tsis muaj tshuaj lom. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm tib neeg cov kev cai rau kev nyab xeeb thiab kev tiv thaiv ib puag ncig, daim ntawv thov kev cia siab ntawm ammonium polyphosphate hauv cov tua hluav taws yuav dav dua.
