Usoro na Uru nke Ammonium Polyphosphate Flame Retardant

Enwere ike kewaa ihe na-egbochi ire ọkụ nke Ammonium polyphosphate (APP) n'ụdị atọ dabere na ọkwa polymerization ya: obere, ọkara, na elu polymerization. Ka ogo polymerization dị elu, otú ahụ ka mmiri na-agbaze nke ọma, na nke ọzọ. N'usoro, enwere ike kewaa ya n'ụdị kristal na amorphous, ebe kristal APP bụ nnu mmiri na-anaghị agbaze ogologo. Usoro molekul izugbe nke APP bụ (NH₄)ₙ₊₂PₙO₃ₙ₊₁. Mgbe n sitere na 10 ruo 20, ọ na-agbaze mmiri; mgbe n gafere 20, ọ na-aghọ ihe na-anaghị agbaze. APP anaghị egbu egbu, enweghị isi, anaghị emebi emebi, ma na-egosipụta obere hygroscopicity, nkwụsi ike okpomọkụ dị elu, yana arụmọrụ dị mma dị ka ihe na-egbochi ire ọkụ na-enweghị halogen.

Usoro Mgbochi Ọkụ nke APP:
Mgbe a na-ekpo ọkụ, APP na-agbaze wee mepụta poly-/metaphosphoric acid, nke na-akwalite mmiri ịkpọ nkụ na carbonation n'elu ihe ndị dị ndụ. Ọ na-agbasa mgbe a na-ekpo ọkụ, na-emepụta oyi akwa nchebe nke na-ekewapụ ihe ahụ na oxygen, si otú a na-eme ka ọkụ ghara ịdị. Na mgbakwunye, mmebi okpomọkụ nke APP na-ewepụta gas ndị na-anaghị ere ọkụ dịka CO₂ na NH₃, nke na-ebelata mkpokọta oxygen na ikuku, na-ebelatakwa ọkọnọ oxygen. Àgwà ndị a na-eme ka obere ikuku anwụrụ ọkụ, enweghị mmepụta gas na-egbu egbu, na ihe ndị na-eme ka onwe ya gbanyụọ. Ihe pụrụ iche bụ na enweghị gas na-egbu egbu abụghị naanị ihe dị mma maka gburugburu ebe obibi kamakwa ọ dị mkpa maka nchekwa ndụ - ọnụ ọgụgụ na-egosi na ihe karịrị 80% nke ọnwụ na nnukwu ihe mberede ọkụ na-akpata site na anwụrụ ọkụ na-egbu egbu sitere na plastik na-ere ọkụ, ihe ndị dị na eletrọnịkị, na ihe ndị ọzọ, kama ọkụ ahụ n'onwe ya.

Onye Mmepụta APP Flame Retardant:
Taifeng Flame Retardant na-eji teknụzụ microencapsulation dị elu nke mba ụwa iji mepụta APP dị elu nke nwere phosphorus na nitrogen dị elu. Ngwaahịa a nwere nkwụsi ike okpomọkụ dị mma, obere mmiri na-agbaze, pH dị nso na-anọpụ iche, yana arụmọrụ dị elu nke na-egbochi ire ọkụ. Ọ bụ ntụ ntụ ọcha siri ike, enweghị hygroscopic, anaghị ere ọkụ, ma na-egosipụta oke ibu molekul (n > 1200), nkwụsi ike, na iguzogide ihu igwe. A na-ejikarị ya eme ihe n'ọtụtụ ebe na mkpuchi ọkụ nke dabere na mmiri, mkpuchi ákwà, yana dị ka ihe dị mkpa na thermoplastics na-egbochi ire ọkụ. Ngwaahịa a na-ekpuchi na-eme ọgwụgwọ elu maka mmezi ka mma, mmụba nke iguzogide mmiri, mmụba nke pH alkaline, na ọbụna obere mmiri na-agbaze.
