Ammonium Polyphosphate Flame Retardant Mechanism na Uru

Ammonium polyphosphate (APP) ọkụ retardant nwere ike kewaa n'ime atọ ụdị dabere ogo ya polymerization: obere, ọkara, na elu polymerization. Nke dị elu nke ogo polymerization, na-ebelata mmiri solubility, na nke ọzọ. N'usoro, enwere ike kewaa ya n'ime ụdị kristal na amorphous, na APP crystal bụ nnu ogologo nke mmiri na-adịghị edozi. Usoro molekụla izugbe nke APP bụ (NH₄)ₙ₊₂PₙOₙ₊₁. Mgbe n sitere na 10 ruo 20, ọ na-agbaze mmiri; mgbe n gafere 20, ọ na-aghọ ihe na-adịghị edozi. APP anaghị egbu egbu, enweghị isi, anaghị emebi emebi, na-egosipụtakwa hygroscopicity dị ala, nkwụsi ike dị elu, yana arụmọrụ dị mma dị ka ọkụ na-enweghị halogen.

Usoro APP na-egbochi ire ọkụ:
Mgbe a na-ekpo ọkụ, APP na-agbaze ka ọ bụrụ poly-/metaphosphoric acid, nke na-akwalite akpịrị ịkpọ nkụ na carbonization n'elu ihe ndị dị ndụ. Ọ na-agbasa n'elu ikpo ọkụ, na-etolite oyi akwa nke na-ekewapụta ihe na ikuku oxygen, si otú ahụ na-enweta ọkụ ọkụ. Na mgbakwunye, ire ere ọkụ nke APP na-ewepụta ikuku na-anaghị agba ọkụ dị ka CO₂ na NH₃, nke na-ebelata mkpokọta oxygen na ikuku, na-ebelata ikuku oxygen. Àgwà ndị a na-ebute obere anwụrụ ọkụ, enweghị mmepụta gas na-egbu egbu, na ihe na-ekpochapụ onwe ya. N'ụzọ dị ịrịba ama, enweghị gas na-egbu egbu abụghị nanị enyi na gburugburu ebe obibi kamakwa ọ dị oke mkpa maka nchekwa ndụ - ọnụ ọgụgụ na-egosi na ihe karịrị 80% nke ndị na-egbu egbu na nnukwu ọkụ ọkụ na-akpata site na uzu ọkụ na-egbu egbu sitere na plastik na-ere ọkụ, ngwa eletriki, na ihe ndị ọzọ, kama ọkụ n'onwe ya.

Onye nrụpụta APP Flame Retardant:
Taifeng Flame Retardant na-eji teknụzụ microencapsulation multi-layer dị elu nke mba ụwa iji mepụta APP dị elu-polymerization nwere nnukwu phosphorus na ọdịnaya nitrogen. Ngwaahịa a na-egosipụta nkwụsi ike ọkụ dị mma, obere mmiri solubility, pH na-anọpụ iche, yana nnukwu ọkụ na-egbochi ọkụ. Ọ bụ ntụ ntụ na-acha ọcha siri ike, nke na-abụghị hygroscopic, enweghị ọkụ, ma gosipụta ịdị arọ molekụla dị elu (n> 1200), nkwụsi ike, na nguzogide ihu igwe. A na-eji ya eme ihe n'ọtụtụ ebe na mkpuchi ọkụ na-ekpuchi mmiri, akwa akwa akwa, yana dịka ihe dị mkpa na ọkụ ọkụ ọkụ ọkụ ọkụ. Ngwaahịa a kpuchiri ekpuchi na-enweta ọgwụgwọ elu maka ndakọrịta ka mma, nkwalite mmiri na-eguzogide mmiri, pH alkaline, na ọbụna ala mmiri solubility.
