Thepa ea 'Mele le ea Lik'hemik'hale	Ammonium polyphosphate e ka aroloa ka mefuta e meraro ho latela boemo ba eona ba polymerization: polymer e tlase, polymer e mahareng le polymer e phahameng. Ha tekanyo ea polymerization e phahame, ho fokotseha ha metsi ho qhibiliha. Ho ea ka sebopeho sa eona, e ka aroloa ka mefuta ea crystalline le amorphous. Crystalline ammonium polyphosphate ke polyphosphate e sa keneng ka metsing le ketane e telele. Ho na le mefuta e mehlano ho tloha ho I ho ea ho mofuta oa V.
Sebelisa	Inorganic additive flame retardant, e sebelisoang ha ho etsoa liphahlo tse thibelang malakabe, lipolasetiki tse thibelang malakabe le lihlahisoa tsa rabara tse thibelang mollo, joalo-joalo. Haholo-holo e sebelisoa ka liphahlo tse thibelang mollo le li-resin tsa thermosetting (tse kang polyurethane rigid foam, UP resin, epoxy resin, joalo-joalo), hape e ka sebelisoa bakeng sa ho thibela lelakabe la fiber, lehong le lihlahisoa tsa rabara. Kaha APP e na le boima bo phahameng ba molek'hule (n> 1000) le botsitso bo phahameng, e ka boela ea sebelisoa e le motsoako o ka sehloohong o sebetsang oa intumescent flame retardant thermoplastics, haholo-holo ho PP ho fihlela ho UL 94-Vo bakeng sa ho etsa likarolo tsa elektroniki.

Ammonium polyphosphate (PAAP ka bokhuts'oane) ke polima e sa sebetseng e nang le thepa e thibelang mollo le thepa e sa cheng. Sebopeho sa eona sa limolek'hule se na le li-polymers tsa phosphate le ammonium ions.

Ammonium polyphosphate e sebelisoa haholo linthong tse thibelang lelakabe, lisebelisoa tse refractory le liphahlo tse thibelang mollo. E ka ntlafatsa ts'ebetso e thibelang malakabe ka katleho ea thepa, ea liehisa ts'ebetso ea ho tuka, ea thibela ho ata ha malakabe, 'me ea fokotsa ho lokolloa ha likhase tse kotsi le mosi.

Mokhoa oa ho lokisa ammonium polyphosphate hangata o kenyelletsa karabelo ea asiti ea phosphoric le letsoai la ammonium. Nakong ea karabelo, maqhama a lik'hemik'hale pakeng tsa phosphate le ammonium ions a thehoa, ho etsa li-polymers tse nang le lihlopha tse ngata tsa phosphate le ammonium ion.

Tlhahisoleseding ea Polokeho: Ammonium polyphosphate e batla e bolokehile tlas'a maemo a tloaelehileng a tšebeliso le polokelo. Qoba ho hema lerole la ammonium polyphosphate kaha le ka baka mathata a ho hema. Ha u sebetsana le ammonium polyphosphate, latela ka tieo mekhoa e sebetsang ea ts'ireletso 'me u boloke hantle le ho lahla motsoako.
