Ammonium polyphosphate (APP) yog siv dav siv cov nplaim hluav taws thiab cov chiv, paub txog nws cov txiaj ntsig hauv kev txhim kho hluav taws kub hauv ntau yam ntaub ntawv. Ib qho ntawm cov txheej txheem tshuaj ntsuam xyuas tseem ceeb ua haujlwm kom nkag siab txog cov khoom siv thermal ntawm APP yog Thermogravimetric Analysis (TGA). TGA ntsuas qhov kev hloov pauv hauv huab hwm coj raws li nws tau ua kom sov, txias, lossis tuav ntawm qhov kub thiab txias, muab kev pom zoo rau nws cov thermal stability, decomposition tus cwj pwm, thiab tag nrho cov kev ua tau zoo nyob rau hauv daim ntawv thov.
Qhov tseem ceeb ntawm TGA hauv kev tshawb fawb ntawm ammonium polyphosphate tsis tuaj yeem hais ntau dhau. Ua ntej thiab qhov tseem ceeb, TGA pab txiav txim siab thermal stability ntawm APP. Nkag siab txog qhov kub thiab txias uas APP tseem nyob ruaj khov yog qhov tseem ceeb rau nws daim ntawv thov hauv hluav taws kub retardancy. Yog tias APP decomposes ntawm qhov kub qis dua, nws yuav tsis ua haujlwm zoo hauv kev tiv thaiv cov ntaub ntawv los ntawm hluav taws, vim nws yuav plam nws cov nplaim hluav taws ua ntej cov khoom nws tus kheej mus txog qhov kub thiab txias. TGA tso cai rau cov kws tshawb fawb los txheeb xyuas qhov pib ntawm decomposition, ua rau lawv ua kom zoo tshaj plaws rau cov ntawv thov tshwj xeeb.
Ntxiv mus, TGA muab kev nkag siab rau hauv cov khoom decomposition ntawm APP. Lub thermal degradation ntawm ammonium polyphosphate tuaj yeem ua rau tso tawm ntau yam roj, suav nrog ammonia thiab phosphoric acid. Los ntawm kev txheeb xyuas qhov poob ntawm qhov sib txawv ntawm qhov kub thiab txias, cov kws tshawb fawb tuaj yeem txheeb xyuas qhov kub thiab txias qhov twg cov roj no tawm. Cov ntaub ntawv no yog qhov tseem ceeb rau kev nkag siab txog cov txheej txheem ntawm cov nplaim hluav taws xob, vim tias qhov tso tawm ntawm cov roj uas tsis yog nplaim hluav taws tuaj yeem ua rau cov nplaim hluav taws kub hnyiab tau thiab txo cov nplaim taws tag nrho ntawm cov khoom.
Lwm qhov tseem ceeb ntawm TGA yog nws lub luag haujlwm hauv kev tsim cov APP-based composites. Hauv ntau daim ntawv thov, APP ua ke nrog lwm cov ntaub ntawv los txhim kho nws cov kev ua tau zoo. TGA tuaj yeem siv los ntsuas qhov kev sib raug zoo thiab kev ruaj ntseg ntawm cov khoom sib xyaw hauv qab thermal stress. Los ntawm kev ntsuam xyuas tus cwj pwm thermal ntawm cov ntaub ntawv sib xyaw, cov kws tshawb fawb tuaj yeem txiav txim siab qhov zoo tshaj plaws ntawm APP rau lwm cov khoom, kom ntseeg tau tias cov khoom kawg tswj nws cov nplaim hluav taws xob thaum ua tiav cov yam ntxwv xav tau thiab cov yam ntxwv thermal.
Tsis tas li ntawd, TGA tuaj yeem pab tswj tau zoo thaum lub sijhawm tsim cov ammonium polyphosphate. Los ntawm kev tsim cov thermal profile rau APP, manufacturers tuaj yeem saib xyuas qhov sib xws thiab zoo ntawm lawv cov khoom. Kev sib txawv los ntawm kev tsim thermal tus cwj pwm yuav qhia tau hais tias muaj teeb meem hauv cov txheej txheem tsim khoom, xws li kev ua tsis tiav lossis kev sib kis, uas tuaj yeem cuam tshuam qhov ua tau zoo ntawm cov nplaim hluav taws.
Hauv kev xaus, qhov tseem ceeb ntawm TGA hauv kev kawm ntawm ammonium polyphosphate yog nyob rau hauv nws lub peev xwm los muab cov ntaub ntawv tseem ceeb ntawm thermal stability, decomposition cwj pwm, thiab compatibility nrog rau lwm yam ntaub ntawv. Cov txheej txheem kev tshuaj xyuas no tsis yog tsuas yog txhim kho peb txoj kev nkag siab ntawm APP kev ua tau zoo raws li cov nplaim hluav taws kub hnyiab tab sis kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txhim kho thiab kev tswj xyuas zoo ntawm APP-based khoom. Raws li kev lag luam txuas ntxiv mus nrhiav kev daws teeb meem kev nyab xeeb hluav taws zoo, qhov kev nkag siab tau txais los ntawm TGA yuav tseem muaj txiaj ntsig rau kev nce qib ntawm ammonium polyphosphate hauv ntau qhov chaw.
