Ammonium Polyphosphate (APP)
Ammonium Polyphosphate (APP) bụ ihe na-egbochi ire ọkụ nke a na-ejikarị eme ihe, nke a na-ejikarị eme ihe n'ime mkpuchi intumescent retardant. Mkpuchi intumescent retardant bụ ihe mkpuchi pụrụ iche nke na-egbochi ọkụ. Isi ọrụ ya bụ ịmepụta oyi akwa mkpuchi okpomọkụ site na gas retardant nke mgbasa na-emepụta iji gbochie mgbasa nke ọkụ ma gbochie mmebi nke ihe owuwu mgbe ọkụ mere.
Ụkpụrụ
A na-eji Ammonium polyphosphate eme ihe dị ka ihe na-egbochi ọkụ bụ isi na mkpuchi ihe na-egbochi ọkụ. Ammonium polyphosphate nwere ezigbo ihe na-egbochi ọkụ. Mgbe okpomọkụ rịrị elu, ọ ga-ere ere iji mepụta phosphoric acid na gas ammonia. Ngwaahịa ndị a nwere ike iwepụ ihe ndị dị ndụ n'ime ka ọ bụrụ unyi, si otú a na-egbochi oxygen na okpomọkụ, si otú a na-emepụta mmetụta na-egbochi ọkụ. N'otu oge ahụ, ammonium polyphosphate na-agbasakwa. Mgbe a na-ekpo ọkụ ma na-ere ọkụ, ọ ga-emepụta nnukwu gas, nke mere na mkpuchi ihe na-egbochi ọkụ na-emepụta oyi akwa carbon dị arọ, nke na-ekewapụ isi iyi ọkụ ahụ na kọntaktị ma na-egbochi ọkụ ịgbasa.
Uru
Ammonium polyphosphate nwere uru dị na ezigbo nkwụsi ike okpomọkụ, iguzogide mmiri na mmiri, ọ naghị egbu egbu ma ọ bụ na-emetọ gburugburu ebe obibi, yabụ a na-eji ya eme ihe nke ukwuu na mkpuchi na-egbochi ọkụ. Enwere ike itinye ya na ihe ndabere nke mkpuchi na-egbochi ọkụ iji mepụta sistemụ mkpuchi na-egbochi ọkụ zuru oke yana ihe ndị ọzọ na-egbochi ọkụ, ihe njikọta na ihe njupụta. N'ozuzu, itinye ammonium polyphosphate na mkpuchi na-egbochi ọkụ nwere ike inye ezigbo njirimara mgbochi ọkụ na mmụba, ma chebe nchekwa nke ụlọ na ihe owuwu n'ọkụ nke ọma.
Ngwa
Dịka ihe dị iche iche si dị, ngwa ammonium polyphosphate na mkpuchi na-egosipụtakarị na:
1. Mkpuchi FR nke na-egbuke egbuke na nhazi ígwè nke ụlọ.
2. Mkpuchi ákwà dị n'azụ ákwà mgbochi, mkpuchi mkpuchi ojii.
3. Eriri FR.
4. Oke eji arụ ụlọ, ụgbọelu, na mkpuchi elu ụgbọ mmiri.
