Ammonium polyphosphate (APP) ke ntho e thibelang lelakabe le manyolo e sebelisoang haholo, e tsejoang ka katleho ea eona ho matlafatsa khanyetso ea mollo linthong tse fapaneng. E 'ngoe ea mekhoa e hlokolosi ea tlhahlobo e sebelisitsoeng ho utloisisa thepa ea mocheso ea APP ke Thermogravimetric Analysis (TGA). TGA e lekanya phetoho ea boima ba ntho ha e futhumatsoa, e pholile, kapa e ts'oaroa ka mocheso o sa fetoheng, e fana ka leseli la bohlokoa mabapi le botsitso ba eona ba mocheso, boitšoaro ba ho bola, le ts'ebetso ka kakaretso lits'ebetsong.
Bohlokoa ba TGA thutong ea ammonium polyphosphate bo ke ke ba fetisoa. Pele ho tsohle, TGA e thusa ho fumana botsitso ba mocheso oa APP. Ho utloisisa mefuta e fapaneng ea mocheso eo APP e lulang e tsitsitse ho eona ke habohlokoa bakeng sa ts'ebeliso ea eona ho thibela mollo. Haeba APP e bola ka mocheso o tlase, e kanna ea se sebetse hantle ho sireletseng lisebelisoa mollong, kaha e ka lahleheloa ke thepa ea eona e thibelang malakabe pele thepa ka boyona e fihla mocheso o boima. TGA e lumella bafuputsi ho tseba ho qala ha ho bola, ho ba nolofalletsa ho ntlafatsa liforomo bakeng sa lits'ebetso tse ikhethileng.
Ho feta moo, TGA e fana ka leseli mabapi le lihlahisoa tsa ho bola tsa APP. Ho senyeha ha mocheso oa ammonium polyphosphate ho ka lebisa ho lokolloa ha likhase tse fapa-fapaneng, ho akarelletsa ammonia le phosphoric acid. Ka ho hlahloba tahlehelo ea boima ka mekhahlelo e fapaneng ea mocheso, bafuputsi ba ka tseba mefuta e itseng ea mocheso moo likhase tsena li lokolloang teng. Tlhahisoleseding ena ke ea bohlokoa bakeng sa ho utloisisa mochine oa ho lieha ha lelakabe, kaha ho lokolloa ha likhase tse sa cheng ho ka fokotsa mouoane o tukang le ho fokotsa ho chesa ka kakaretso ha thepa.
Karolo e 'ngoe ea bohlokoa ea TGA ke karolo ea eona ho thehoeng ha metsoako e thehiloeng ho APP. Lits'ebetsong tse ngata, APP e kopantsoe le lisebelisoa tse ling ho ntlafatsa ts'ebetso ea eona. TGA e ka sebelisoa ho lekola tšebelisano le botsitso ba li-composites tsena tlas'a khatello ea mocheso. Ka ho lekola boits'oaro ba mocheso oa lisebelisoa tse kopaneng, bafuputsi ba ka tseba litekanyo tse nepahetseng tsa APP ho likarolo tse ling, ho etsa bonnete ba hore sehlahisoa sa ho qetela se boloka thepa ea sona e thibelang malakabe ha se ntse se fihlela litšobotsi tse lakatsehang tsa mochini le mocheso.
Ho feta moo, TGA e ka thusa ho laola boleng nakong ea tlhahiso ea ammonium polyphosphate. Ka ho theha profil ea mocheso bakeng sa APP, bahlahisi ba ka lekola botsitso le boleng ba lihlahisoa tsa bona. Ho kheloha ho tloha boitšoarong bo behiloeng ba mocheso ho ka 'na ha bontša mathata a ts'ebetso ea tlhahiso, joalo ka ho se phethahale kapa tšilafalo, e ka senyang katleho ea sehlaseli sa mollo.
Qetellong, bohlokoa ba TGA thutong ea ammonium polyphosphate bo itšetlehile ka bokhoni ba eona ba ho fana ka tlhahisoleseding ea bohlokoa mabapi le botsitso ba mocheso, boitšoaro ba ho bola, le ho lumellana le lisebelisoa tse ling. Mokhoa ona oa ho sekaseka ha o ntlafatse kutloisiso ea rona ea tšebetso ea APP joalo ka ntho e thibelang lelakabe empa o boetse o bapala karolo ea bohlokoa ntlafatsong le taolong ea boleng ba lihlahisoa tse thehiloeng ho APP. Ha liindasteri li ntse li tsoela pele ho batla litharollo tse sebetsang tsa tšireletso ea mollo, lintlha tse fumanoeng ho tsoa ho TGA li tla lula li le bohlokoa ho ntšetseng pele tšebeliso ea ammonium polyphosphate masimong a fapaneng.
Sichuan Taifeng New Flame Retardant Co., Ltdke moetsi ea nang le boiphihlelo ba lilemo tse 22 ea sebetsanang le tlhahiso ea li-ammonium polyphosphate flame retardants, lihlahisoa tsa rona li romelloa ka bongata mose ho maoatle.
Moemeli oa rona oa mollo retardantTF-241e sebelisana hantle le tikoloho ebile e na le moruo, e na le ts'ebeliso e tsoetseng pele ho PP,PE, HEDP.
