Ammonium Polyphosphate (APP)
Ammonium Polyphosphate (APP) yog ib yam khoom siv uas feem ntau siv los tiv thaiv hluav taws, siv dav hauv cov txheej txheej tiv thaiv hluav taws kub. Cov txheej txheej tiv thaiv hluav taws kub yog ib txheej txheej tiv thaiv hluav taws tshwj xeeb. Nws lub luag haujlwm tseem ceeb yog los tsim ib txheej rwb thaiv tsev kub los ntawm cov pa roj uas tsim los ntawm kev nthuav dav kom tiv thaiv hluav taws tsis txhob kis mus rau lwm qhov thiab tiv thaiv kev puas tsuaj rau cov qauv thaum muaj hluav taws kub.
Lub Ntsiab Cai
Ammonium polyphosphate yog siv ua cov tshuaj tiv thaiv hluav taws tseem ceeb hauv cov txheej txheej tiv thaiv hluav taws kub intumescent. Ammonium polyphosphate muaj cov yam ntxwv tiv thaiv hluav taws kub zoo. Thaum qhov kub nce siab, nws yuav lwj mus ua cov phosphoric acid thiab ammonia gas. Cov khoom no tuaj yeem ua rau cov organic matter qhuav mus ua cov thee, yog li ntawd nws thiaj li rwb thaiv cov pa oxygen thiab cua sov, yog li ua rau muaj cov nyhuv tiv thaiv hluav taws kub. Tib lub sijhawm, ammonium polyphosphate kuj tseem dav heev. Thaum nws raug cua sov thiab lwj, nws yuav tsim cov roj ntau heev, yog li ntawd cov txheej txheej tiv thaiv hluav taws kub intumescent tsim cov txheej carbon tuab uas tiv thaiv hluav taws kub, uas ua rau cov qhov chaw hluav taws kub tsis txhob sib cuag thiab tiv thaiv hluav taws kub kom tsis txhob kis mus.
Cov txiaj ntsig
Ammonium polyphosphate muaj qhov zoo ntawm kev ruaj khov zoo thermal, tiv taus dej thiab noo noo, tsis muaj tshuaj lom thiab tsis ua rau ib puag ncig puas tsuaj, yog li nws siv dav hauv cov txheej txheem tiv thaiv hluav taws kub intumescent. Nws tuaj yeem ntxiv rau cov khoom siv hauv paus ntawm cov txheej txheem tiv thaiv hluav taws kom tsim tau cov txheej txheem tiv thaiv hluav taws kub tiav nrog rau lwm cov tshuaj tiv thaiv hluav taws, cov khoom khi thiab cov khoom sau. Feem ntau, kev siv ammonium polyphosphate hauv cov txheej txheem tiv thaiv hluav taws kub intumescent tuaj yeem muab cov yam ntxwv zoo heev rau kev tiv thaiv hluav taws thiab kev nthuav dav, thiab tiv thaiv kev nyab xeeb ntawm cov tsev thiab cov qauv hauv hluav taws.
Daim Ntawv Thov
Raws li cov ntaub ntawv sib txawv xav tau ntawm APP, Daim ntawv thov ntawm ammonium polyphosphate hauv txheej yog feem ntau pom hauv:
1. Txheej txheej FR Intumescent rau ntawm cov qauv hlau hauv tsev.
2. Cov ntaub thaiv qhov rai, cov xim dub.
3. FR cable.
4. Siv loj heev hauv kev tsim kho, kev tsav dav hlau, cov txheej txheem saum npoo ntawm nkoj.
Cov qauv piv txwv ntawm cov txheej txheem intumescent
