Ammonium polyphosphate (APP) i roto i ngā hiri intumescent

I roto i te whakawhānui ake i ngā hanganga hiri, he mea nui te ammonium polyphosphate (APP) ki te whakapakari i te ātete ahi.
He mea noa te whakamahi i te APP hei ārai mura i roto i ngā whakatakotoranga hiri whakawhanui. Ina tukuna ki ngā pāmahana teitei i te wā o te ahi, ka pāngia te APP e tētahi huringa matū matatini. Ka whakaoho te wera i te tukunga o te waikawa phosphoric, ka tauhohe ki ngā rauropi kore utu i puta mai i te tukanga tahunga. Ka whakatairangahia e tēnei tauhohenga matū te hanganga o tētahi paparanga waro matotoru. Ka mahi tēnei paparanga waro hei ārai ārai, ka whakawhāiti i te whakawhiti o te wera me te hāora ki ngā rauemi o raro, ā, ka ārai i te horapa o ngā mura.
Hei tāpiritanga, ka mahi te APP hei ārai mura intumescent i roto i ngā whakatakotoranga hiri whakawhanui. Ina pāngia e te ahi, ka pupuhi, ka wera, ka hanga he paparanga ārai tiaki ngā tāpiringa intumescent, tae atu ki te APP. Ka whai wāhi tēnei paparanga ki te whakaiti i te whakawhiti wera me te tukunga o ngā hau kore e mura, ā, ka whakaroa i te horapa o te ahi.
Hei tāpiritanga, ko te noho mai o te APP i roto i ngā hiri e whakawhanui ana ka whakarei ake i tō rātou ātete ahi whānui, ā, ka tutuki hoki i ngā paerewa haumaru ahi tino pakari. Ko te waro i hangaia hei hua o te tauhohenga APP ka ārai pai i ngā rauemi o raro, ka whakarato i te wā tāpiri mō te urupare ohorere me te whakawātea i te wāhi ka puta he ahi.
Hei whakamutunga, i roto i ngā hanganga hiri whakawhanui, ko te whakaurunga o te ammonium polyphosphate ka tino whakarei ake i te ātete ahi mā te whakatairanga i te hanganga o tētahi paparanga waro tiaki, te whakaiti i te whakawhiti wera me te hāora, me te whakarato i tētahi ārai whai hua ki te horapa o ngā mura. Ka whai wāhi tēnei ki te haumaru ahi whānui me te mahi a ngā hua hiri whakawhanui i roto i ngā tono maha.
