I-Ammonium Polyphosphate' esetyenziswa kwizixhobo zokucima umlilo zomgubo owomileyo

I-Ammonium polyphosphate (APP) yikhompawundi engaphiliyo esetyenziswa kakhulu kwizixhobo zokucima umlilo kunye nezicima-mlilo. Ifomyula yayo yekhemikhali yi (NH4PO3)n, apho i-n imele inqanaba le-polymerization. Ukusetyenziswa kwe-APP kwizixhobo zokucima umlilo kusekelwe kakhulu kwiimpawu zayo ezibalaseleyo zezixhobo zokucima umlilo kunye nokunciphisa umsi.

Okokuqala, indima ephambili ye-APP kwizicimi-mlilo kukuba yinto ethintela ukusasazeka kwamalangatye kunye nenkqubo yokutsha ngeendlela ezahlukeneyo. I-APP iyabola kumaqondo obushushu aphezulu ukuze ivelise i-phosphoric acid kunye ne-ammonia. I-phosphoric acid yenza ifilimu ekhuselayo efana neglasi kumphezulu wokutsha, yahlula ioksijini kunye nobushushu, ngaloo ndlela ithintela ukuqhubeka kokutsha. I-Ammonia inceda ekunciphiseni igesi evuthayo kwindawo yokutsha kwaye inciphise ubushushu belangatye.

Okwesibini, i-APP ineempawu ezilungileyo zokuthintela umsi. Emlilweni, umsi awunciphisi nje kuphela ukubonakala kwaye wonyusa ubunzima bokuphuma, kodwa ukwanazo neegesi ezininzi ezinobuthi, nto leyo ebeka umngcipheko omkhulu kwimpilo yabantu. I-APP inokunciphisa ngempumelelo ukuveliswa komsi ngexesha lenkqubo yokutsha kwaye inciphise ubungozi bomlilo.

I-Ammonium polyphosphate isetyenziswa kwizixhobo zokucima umlilo ngeendlela ezahlukeneyo, ezona zixhaphakileyo kuzo zizicimi-mlilo zomgubo owomileyo kunye nezicimi-mlilo zefoam. Kwizixhobo zokucima umlilo zomgubo owomileyo, i-ammonium polyphosphate yenye yezona zithako ziphambili kwaye ixutywa nezinye iikhemikhali ukwenza umgubo owomileyo ocima umlilo osebenzayo. Lo mgubo owomileyo unokugquma ngokukhawuleza izinto ezitshayo, wahlukanise ioksijini, kwaye ucime ilangatye ngokukhawuleza. Kwizixhobo zokucima umlilo zefoam, i-ammonium polyphosphate ixutywa nearhente yefoam ukwenza ifoam ezinzileyo egubungela umphezulu wezinto ezitshayo, idlala indima ekupholiseni nasekuhlukaniseni ioksijini.

Ukongeza, i-ammonium polyphosphate ikwanazo neengenelo zokukhusela okusingqongileyo kunye nokuba netyhefu ephantsi. Xa kuthelekiswa ne-halogenated flame retardants zemveli, i-ammonium polyphosphate ayikhuphi i-halides eyingozi ngexesha lokutsha, nto leyo enciphisa umonakalo owenzeka kwindalo nakwimizimba yabantu. Ke ngoko, ukusetyenziswa kwe-ammonium polyphosphate kwizixhobo zokucima umlilo zanamhlanje kuye kwafumana ingqwalasela engakumbi.

Ngokubanzi, ukusetyenziswa kwe-ammonium polyphosphate kwizixhobo zokucima umlilo kuneengenelo ezininzi, kubandakanya ukusebenza kakuhle kokurhoxisa umlilo, isiphumo esihle sokuthintela umsi, kunye nokukhuselwa kwendalo kunye nokungabi natyhefu. Ngokuphucuka kwesayensi netekhnoloji kunye nokuphuculwa kweemfuno zabantu zokhuseleko kunye nokukhuselwa kwendalo, amathuba okusetyenziswa kwe-ammonium polyphosphate kwizixhobo zokucima umlilo aya kuba banzi.
