Ammonium Polyphosphate (APP)
Ammonium Polyphosphate (APP) yog cov nplaim hluav taws kub nyhiab, siv dav hauv cov hluav taws kub retardant txheej.Intumescent hluav taws retardant txheej yog tshwj xeeb hluav taws kub retardant txheej.Nws lub luag haujlwm tseem ceeb yog tsim cov txheej txheem hluav taws xob los ntawm cov nplaim hluav taws xob uas tsim los ntawm kev nthuav dav los tiv thaiv kev sib kis ntawm hluav taws thiab tiv thaiv kev puas tsuaj rau cov qauv thaum muaj hluav taws kub.
Txoj Cai
Ammonium polyphosphate yog siv los ua cov nplaim hluav taws kub retardant hauv intumescent hluav taws kub retardant txheej.Ammonium polyphosphate muaj cov nplaim hluav taws zoo.Thaum kub nce, nws yuav decompose los tsim phosphoric acid thiab ammonia gas.Cov khoom no muaj peev xwm dehydrate organic teeb meem rau hauv charcoal, yog li insulating oxygen thiab tshav kub, yog li ua ib tug nplaim retardant nyhuv.Nyob rau tib lub sijhawm, ammonium polyphosphate kuj nthuav dav.Thaum nws yog rhuab thiab decomposed, nws yuav tsim ib tug loj npaum li cas ntawm cov roj, thiaj li hais tias cov intumescent fireproof txheej tsim ib tug tuab fireproof carbon txheej, uas zoo cais qhov hluav taws kub los ntawm kev sib cuag thiab tiv thaiv hluav taws los ntawm kev sib kis.
Qhov zoo
Ammonium polyphosphate muaj qhov zoo ntawm qhov zoo thermal stability, dej thiab noo noo tsis kam, tsis muaj tshuaj lom thiab tsis muaj kuab paug rau ib puag ncig, yog li nws yog dav siv hauv intumescent fireproof coatings.Nws tuaj yeem muab ntxiv rau hauv cov khoom siv hluav taws kub retardant coatings los ua kom tiav cov hluav taws kub retardant txheej ua ke nrog rau lwm cov nplaim hluav taws kub hnyiab, binders thiab fillers.Feem ntau, daim ntawv thov ntawm ammonium polyphosphate nyob rau hauv intumescent hluav taws retardant txheej yuav muab tau zoo heev nplaim retardancy thiab nthuav cov yam ntxwv, thiab zoo tiv thaiv kev ruaj ntseg ntawm lub tsev thiab cov qauv nyob rau 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 cuam tshuam hauv:
1. Intumescent FR txheej rau sab hauv tsev siv steel qauv.
2. Textile rov qab txheej nyob rau hauv cov ntaub, blackout txheej.
3. FR cable.
4. Loj heev siv nyob rau hauv kev tsim kho, aviation, ships nto txheej.
