Lub mechanism ntawm flame retardantAPP muaj peev xwm muab faib ua cov txheej txheem condensed-phase flame-retardant thiab cov txheej txheem roj-phase flame-retardant. Cov txheej txheem condensed-phase flame-retardant: APP decomposes thaum cua sov rau hauv phosphoric acid derivatives xws li polyphosphoric acid thiab metaphosphoric acid. Cov phosphoric acid derivatives no catalyze qhov kev sib txuas ntawm cov polymers mus rau hauv char, ua rau dehydration thiab carbonization ntawm qhov chaw matrix, tsim ib txheej char uas tsis kub hnyiab. Cov txheej txheem char uas tsis kub hnyiab no txheej lub matrix nto, ua haujlwm ua lub cev thaiv, ncua kev sib pauv ntawm cov khoom kub hnyiab thiab kev coj cua sov, thiab txo qhov nrawm ntawm kev lwj ntawm lub matrix sab hauv.
Txoj kev tiv thaiv hluav taws kub theem roj: APP lwj thaum cua sov los tsim cov pa roj uas tsis kub hnyiab xws li NH3, NO, thiab cov pa dej. Cov pa roj no tsis yog tsuas yog txo qhov concentration ntawm cov pa roj uas kub hnyiab hauv huab cua xwb tab sis kuj ua rau cov txheej char hauv theem condensed nthuav dav, txo qhov kub thiab hloov pauv loj. Ntxiv mus, cov phosphoric acid derivatives tau txais thaum lub sijhawm APP combustion dhau los ntawm cov tshuaj tiv thaiv tsis sib npaug los tsim HPO·, PO2·, thiab PO· cov free radicals. Cov free radicals no tuaj yeem ntes H· thiab OH· cov free radicals tsim los ntawm polymer chain reactions, ua rau muaj kev kub ntxhov thiab txo qhov tso tawm cua sov.
Feem ntau, kev tiv thaiv hluav taws kub theem condensed thiab kev tiv thaiv hluav taws kub theem roj ntawm APP ua haujlwm ua ke. Txawm li cas los xij, kev tiv thaiv hluav taws kub theem roj ntawm APP xav tau kev siv phosphoric acid los tsim cov free radicals. Thaum cov ntsiab lus phosphoric acid txo qis, tag nrho cov txheej char porous kuj txo qis, thiab cov txheej char uas tsim los yuav lwj, txo qhov ua tau zoo ntawm kev tiv thaiv hluav taws kub theem condensed. Yog li ntawd, qee zaum, APP tsuas yog qhia txog kev tiv thaiv hluav taws kub theem condensed, thiab cov nyhuv tiv thaiv hluav taws kub yuav raug txhim kho.
Sichuan Taifeng New Flame Retardant Co., Ltd tau tsim muaj xyoo 2001, feem ntau yog ua cov khoom siv tshuaj phosphate. Xyoo 2011, txhawm rau kom ua raws li kev lag luam hauv tebchaws thiab nrhiav cov cib fim tshiab, lub tuam txhab tau tsom mus rau ammonium polyphosphate thiab teeb tsa chav haujlwm R&D tshwj xeeb rau cov tshuaj halogen-free flame retardant.
Ammonium polyphosphate (APP)thiab hloov kho thiab sib xyaw ua ke raws li APP yog peb cov khoom tseem ceeb. Lawv siv thoob plaws ntau yam lag luam, xws li cov txheej txheem tiv thaiv hluav taws, ntaub, ntawv, masterbatch thiab lwm yam. Peb muaj lub network muag khoom hauv tebchaws thiab thoob ntiaj teb rau thoob ntiaj teb.
Tiv tauj peb rau cov tshuaj tiv thaiv hluav taws.
