Ammonium polyphosphate (APP) yog ib qho tshuaj inorganic uas siv dav dav, feem ntau paub txog nws lub luag haujlwm ua cov tshuaj tiv thaiv hluav taws thiab chiv. Nws cov yam ntxwv tshwj xeeb ua rau nws yog ib qho tseem ceeb hauv ntau yam kev siv, suav nrog cov yas, cov ntaub, thiab cov txheej txheej. Kev nkag siab txog kev ruaj khov ntawm ammonium polyphosphate yog qhov tseem ceeb rau nws siv tau zoo, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub siab.
Feem ntau qhov kev puas tsuaj ntawm ammonium polyphosphate pib ntawm qhov kub siab, feem ntau nyob ib puag ncig 200 txog 300 degrees Celsius (392 txog 572 degrees Fahrenheit). Ntawm cov kub no, cov tshuaj sib xyaw ua rau muaj kev hloov pauv tshuaj uas tuaj yeem ua rau muaj ammonia thiab phosphoric acid tso tawm. Thaum qhov kub nce ntxiv, tshwj xeeb tshaj yog tshaj 300 degrees Celsius, cov txheej txheem kev puas tsuaj nrawm dua, ua rau muaj kev tawg ntawm cov qauv polymeric ntawm APP.
Qhov kev puas tsuaj ntawm ammonium polyphosphate tuaj yeem cuam tshuam los ntawm ntau yam, suav nrog nws qhov hnyav molecular, qhov muaj cov khoom ntxiv, thiab cov qauv tshwj xeeb siv. Piv txwv li, qhov hnyav molecular qis dua APP feem ntau yuav puas tsuaj ntawm qhov kub qis dua piv rau cov qauv hnyav molecular siab dua. Tsis tas li ntawd, qhov muaj lwm cov ntaub ntawv hauv cov qauv sib xyaw tuaj yeem txhim kho lossis tiv thaiv cov txheej txheem puas tsuaj, nyob ntawm lawv cov khoom thermal thiab kev cuam tshuam nrog APP.
Ib qho tseem ceeb ntawm ammonium polyphosphate tus cwj pwm thermal yog nws lub luag haujlwm ua tus tiv thaiv hluav taws. Thaum raug cua sov, APP tuaj yeem tso tawm cov pa roj uas tsis yooj yim hlawv, uas ua rau cov pa roj yooj yim hlawv thiab pab tiv thaiv kev kub hnyiab. Cov khoom no muaj txiaj ntsig zoo rau cov ntawv thov uas muaj kev txhawj xeeb txog kev nyab xeeb hluav taws. Txawm li cas los xij, qhov ua tau zoo ntawm APP ua tus tiv thaiv hluav taws yog khi ze rau nws qhov kev ruaj khov thermal. Yog tias APP lwj sai dhau, nws yuav tsis muab qib kev tiv thaiv xav tau.
Ntxiv mus, cov khoom puas tsuaj ntawm ammonium polyphosphate kuj tseem tuaj yeem muaj feem cuam tshuam rau ib puag ncig thiab tib neeg kev noj qab haus huv. Piv txwv li, kev tso tawm ntawm ammonia tuaj yeem ua rau muaj kuab paug rau huab cua thiab yuav ua rau muaj kev pheej hmoo rau kev noj qab haus huv yog tias nqus tau ntau heev. Yog li ntawd, kev nkag siab txog qhov kub thiab txias ntawm kev puas tsuaj thiab kev tso tawm cov pa roj tom qab ntawd yog qhov tseem ceeb rau kev ntsuas kev nyab xeeb thiab kev cuam tshuam rau ib puag ncig ntawm cov khoom uas muaj APP.
Hauv kev siv ua haujlwm, nws yog ib qho tseem ceeb heev uas yuav tsum xav txog cov xwm txheej ua haujlwm thiab qhov muaj peev xwm ua rau muaj kev puas tsuaj los ntawm cua sov thaum siv ammonium polyphosphate. Cov chaw tsim khoom feem ntau ua qhov kev tshuaj xyuas thermal, xws li kev tshuaj xyuas thermogravimetric (TGA), los txiav txim siab qhov kub thiab txias ntawm kev puas tsuaj thiab los ua kom zoo dua cov qauv rau kev ruaj khov thiab kev ua tau zoo.
Xaus lus, ammonium polyphosphate pib lwj ntawm qhov kub li ntawm 200 txog 300 degrees Celsius, nrog rau kev lwj tseem ceeb tshwm sim ntawm qhov kub siab dua. Nws qhov kev ruaj khov thermal yog qhov tseem ceeb hauv nws qhov ua tau zoo ua ib qho tshuaj tua hluav taws thiab nws cov txiaj ntsig tag nrho hauv ntau yam kev siv. Kev nkag siab txog cov khoom thermal no tsis yog tsuas yog pab txhawb kev tsim cov khoom muaj kev nyab xeeb dua thiab zoo dua tab sis kuj ua kom ua raws li cov cai ib puag ncig thiab kev noj qab haus huv. Thaum kev tshawb fawb txuas ntxiv mus, kev nkag siab ntxiv txog tus cwj pwm thermal ntawm ammonium polyphosphate yuav txhim kho nws cov ntawv thov thiab cov qauv kev nyab xeeb hauv kev lag luam.
