Physical thiab Chemical Properties Ammonium polyphosphate tuaj yeem muab faib ua peb hom raws li nws cov degree ntawm polymerization: tsawg polymer, nruab nrab polymer, thiab siab polymer. Qhov siab dua qhov degree ntawm polymerization, me dua cov dej solubility. Raws li nws cov qauv, nws tuaj yeem muab faib ua crystalline thiab amorphous hom. Crystalline ammonium polyphosphate yog dej insoluble thiab ntev-chain polyphosphate. Muaj tsib qhov txawv ntawm hom I mus rau V.
Siv Inorganic additive nplaim retardant, siv nyob rau hauv kev tsim cov nplaim retardant txheej, nplaim retardant yas thiab nplaim retardant roj hmab khoom, thiab lwm yam.
Nws yog tsuas yog siv nyob rau hauv intumescent hluav taws kub retardant coatings thiab thermosetting resins (xws li polyurethane rigid ua npuas ncauj, UP resin, epoxy resin, thiab lwm yam), thiab tseem yuav siv tau rau nplaim retardant ntawm fiber, ntoo thiab roj hmab khoom. Txij li thaum APP muaj qhov hnyav molecular (n> 1000) thiab ruaj khov siab, nws kuj tseem tuaj yeem siv los ua cov khoom siv tseem ceeb ntawm cov nplaim hluav taws kub retardant thermoplastics, tshwj xeeb tshaj yog nyob rau hauv PP mus txog UL 94-Vo rau kev tsim cov khoom siv hluav taws xob.

Taw qhia

Ammonium polyphosphate (PAAP luv luv) yog ib qho inorganic polymer nrog cov nplaim hluav taws kub thiab hluav taws kub. Nws cov qauv molecular muaj cov polymers ntawm phosphate thiab ammonium ions.

 

Ammonium polyphosphate yog dav siv hauv cov nplaim hluav taws, cov ntaub ntawv refractory thiab hluav taws-retardant txheej. Nws tuaj yeem txhim kho cov nplaim hluav taws xob ua haujlwm zoo ntawm cov khoom siv, ncua cov txheej txheem combustion, inhibit qhov kev sib kis ntawm cov nplaim taws, thiab txo qis cov pa phem thiab pa taws.

 

Cov txheej txheem ntawm kev npaj ammonium polyphosphate feem ntau cuam tshuam nrog cov tshuaj tiv thaiv ntawm phosphoric acid thiab ammonium ntsev. Thaum lub sij hawm cov tshuaj tiv thaiv, tshuaj bonds ntawm phosphate thiab ammonium ions yog tsim, tsim polymers nrog ntau phosphate thiab ammonium ion units.

 

Cov ntaub ntawv kev nyab xeeb: Ammonium polyphosphate muaj kev nyab xeeb nyob rau hauv ib txwm siv thiab khaws cia. Tsis txhob nqus cov plua plav ammonium polyphosphate vim nws tuaj yeem ua rau muaj teeb meem ua pa. Thaum tuav ammonium polyphosphate, nruj me ntsis ua raws li cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm thiab khaws cia thiab pov tseg cov khoom sib xyaw kom zoo.
