Ammonium polyphosphate (APP) thiab APP raws li cov txheej txheem yog cov khoom siv hluav taws xob ntau heev uas siv polyolefins (PE, PP), thermoset resins xws li epoxy resins, polyurethane, unsaturated polyester phenolic resins thiab lwm tus. APP yog ib yam khoom uas tsis muaj teeb meem, khoom noj khoom haus tsis zoo, thiab nws tsis tsim cov pa luam yeeb ntxiv vim muaj cov cuab yeej tshwj xeeb ntawm "Mob Ntseg".
Piv rau lwm lub halogen dawb systems, APP yuav tsum tau txo qis dua. Nyob rau hauv thermoplastic formulations APP exhibits ib tug zoo processability, zoo tuav ntawm mechanical zog thiab zoo hluav taws xob zog.
Nyob hauv cov thermoset, APP siv tau nrog ATH, uas tso cai rau kev txo ntawm tag nrho cov nyiaj ntsuab FR. Cov kev sib txuas ua ke no yog siv los tsim kho thiab siv hluav taws xob. Txoj kev ua tau zoo tuaj yeem kho tau zoo dua thaum qib tas nrho cov qib pib.
Budenheim tau tsim cov ntawv kawm tshiab ntawm APP, uas niaj hnub siv lawv cov ntaub ntawv vim lawv muaj peev xwm los muab ntau yam khoom siv nrog kev tsim kho kev ua haujlwm zoo dua, kev ua kom muaj zog dua FR thiab kev ua kom ntev zog.
Crystalline theem II ammonium polyphosphate yog ib hom kev tiv thaiv ib puag ncig tiv thaiv nonhalogen nplaim hluav taws xob-Nau thiab P. Nws muaj high polymerization degree zoo kub-stability thiab me me hydroscopic. Nws deiffers los ntawm halogen nplaim-retardant, cov kab ua kom cov kab dej ua kom pom thaum lub sijhawm kub nyhiab pom tias cov hluav taws kub thiab cua tsis muaj cua sov Cov cua daj cua dub, tsis muaj tshuaj lom thiab tsis tuaj yeem poob. Li ntawd, nws yog ib yam zoo ntawm kev tiv thaiv ib puag ncig ntawm cov hluav taws xob tsis muaj zog.
Crystalling theem II ammonium polyphosphate muaj ntau yam kev siv. Nws yog tsim rau yas (PP, PE, PVC thiab lwm yam.), Polyester, roj hmab, ntau yam ntxiv hluav taws kub-retardant xim.
