Ammonium polyphosphate (APP) na mkpuchi intumescent

N'ịgbasa usoro sealant, ammonium polyphosphate (APP) na-arụ ọrụ dị oke mkpa n'ịkwalite nguzogide ọkụ.
A na-ejikarị APP dị ka ihe na-egbochi ire ọkụ n'ịgbasa usoro ihe mkpuchi. Mgbe etinyere ya na oke okpomọkụ n'oge ọkụ, APP na-enwe mgbanwe kemịkalụ dị mgbagwoju anya. Okpomọkụ na-eme ka ntọhapụ nke phosphoric acid, nke na-emeghachi omume na radicals free nke usoro combustion na-emepụta. Mmeghachi omume kemịkalụ a na-akwalite guzobe oyi akwa cha cha. Igwe cha cha a na-arụ ọrụ dị ka ihe mgbochi mkpuchi, na-egbochi nfefe ọkụ na ikuku oxygen na ihe ndị dị n'ime ya, si otú a na-egbochi mgbasa ọkụ.
Na mgbakwunye, APP na-arụ ọrụ dị ka ihe na-egbochi ire ọkụ n'ịgbasa usoro sealant. Mgbe ekpughere ya na ọkụ, ihe mgbakwunye intumescent, gụnyere APP, na-enweta usoro ọzịza, chaja, na imepụta oyi akwa mkpuchi mkpuchi. Igwe oyi akwa a na-enye aka n'ibelata nnyefe ọkụ na ntọhapụ nke gas na-adịghị ere ọkụ, si otú a na-ebelata mgbasa ọkụ nke ọma.
Ọzọkwa, ọnụnọ nke APP na ịgbasa sealants na-eme ka nguzogide ọkụ ha zuru oke ma na-ezute ụkpụrụ nchekwa ọkụ siri ike. Char e mere n'ihi mmeghachi omume APP nke ọma na-ekpuchi ihe ndị dị n'ime ya, na-enye oge ọzọ maka nzaghachi mberede na ịpụpụ n'ọnọdụ ọkụ.
N'ikpeazụ, n'ịgbasa usoro ihe mkpuchi mkpuchi, ntinye nke ammonium polyphosphate na-eme ka ọkụ na-eguzogide ọkụ site n'ịkwalite nhazi nke oyi akwa mkpuchi, na-ebelata okpomọkụ na ikuku oxygen, na-enye ihe mgbochi dị irè megide mgbasa ọkụ. Nke a na-enye aka na nchekwa ọkụ zuru oke na arụmọrụ nke ịgbasa ngwaahịa sealant na ngwa dị iche iche.
