I-Ammonium Polyphosphate' esetshenziswa ezicimeni zomlilo zempuphu eyomile

I-Ammonium polyphosphate (APP) iyinhlanganisela engeyona into ephilayo esetshenziswa kakhulu ezithintini zomlilo kanye nezicishamlilo. Ifomula yayo yamakhemikhali ingu-(NH4PO3)n, lapho u-n emele izinga lokwenziwa kwe-polymer. Ukusetshenziswa kwe-APP ezicishamlilo kusekelwe kakhulu ezimpahleni zayo ezinhle kakhulu ezithintini zomlilo kanye nezimpawu zokucindezela intuthu.

Okokuqala, indima eyinhloko ye-APP ezicimeni zomlilo iwukuba yinto evimbela ilangabi. Ivimbela ukusabalala kwamalangabi kanye nenqubo yokushisa ngezindlela ezahlukene. I-APP iyabola emazingeni okushisa aphezulu ukuze ikhiqize i-phosphoric acid kanye ne-ammonia. I-phosphoric acid yakha ifilimu evikelayo efana nengilazi ebusweni bokushisa, ihlukanise umoya-mpilo nokushisa, ngaleyo ndlela ivimbele ukuqhubeka kokushisa. I-Amoniya isiza ekunciphiseni igesi evuthayo endaweni yokushisa futhi yehlise izinga lokushisa kwelangabi.

Okwesibili, i-APP inezakhiwo ezinhle zokuvimbela intuthu. Emlilweni, intuthu ayigcini nje ngokunciphisa ukubonakala futhi yandisa ubunzima bokubaleka, kodwa futhi iqukethe inani elikhulu lamagesi anobuthi, okubangela usongo olukhulu empilweni yabantu. I-APP inganciphisa ngempumelelo ukukhiqizwa kwentuthu ngesikhathi senqubo yokusha futhi inciphise ubungozi bomlilo.

I-Ammonium polyphosphate isetshenziswa ezicimeni zomlilo ngezindlela ezahlukene, ezivame kakhulu kuzo izicimeni zomlilo zempuphu eyomile kanye nezicimeni zomlilo ze-foam. Ezicimeni zomlilo zempuphu eyomile, i-ammonium polyphosphate ingenye yezithako eziyinhloko futhi ixutshwa namanye amakhemikhali ukuze kwakheke impuphu eyomile eqeda umlilo esebenza kahle. Le mpuphu eyomile ingasibekela ngokushesha izinto ezivuthayo, ihlukanise umoya-mpilo, futhi icime ilangabi ngokushesha. Ezicimeni zomlilo ze-foam, i-ammonium polyphosphate ixutshwa ne-ejenti ekhipha amagwebu ukuze kwakheke igwebu eliqinile elimboza ubuso bezinto ezivuthayo, idlala indima ekupholiseni nasekuhlukaniseni umoya-mpilo.

Ngaphezu kwalokho, i-ammonium polyphosphate nayo inezinzuzo zokuvikelwa kwemvelo kanye nobuthi obuphansi. Uma kuqhathaniswa ne-halogenated flame retardants yendabuko, i-ammonium polyphosphate ayikhiphi ama-halide ayingozi ngesikhathi sokusha, okunciphisa umonakalo emvelweni nasemzimbeni womuntu. Ngakho-ke, ukusetshenziswa kwe-ammonium polyphosphate ezicimeni zomlilo zanamuhla kuye kwaqashelwa kakhulu.

Ngokuvamile, ukusetshenziswa kwe-ammonium polyphosphate ezicimeni zomlilo kunezinzuzo eziningi, okuhlanganisa ukusebenza kahle kokuvimbela umlilo, umphumela omuhle wokucindezela intuthu, kanye nokuvikelwa kwemvelo kanye nobuthi obuphansi. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuthuthukiswa kwezidingo zabantu zokuphepha kanye nokuvikelwa kwemvelo, amathuba okusetshenziswa kwe-ammonium polyphosphate ezicimeni zomlilo azoba maningi.
