I-Ammonium Polyphosphate (i-APP)
I-Ammonium Polyphosphate (APP) sisithinteli-mlilo esisetyenziswa kakhulu, sisetyenziswa kakhulu kwiingubo ezithintela umlilo ezingaphakathi. Isithinteli-mlilo esingaphakathi sisixhobo esikhethekileyo esithintela umlilo. Umsebenzi waso ophambili kukwenza umaleko wokukhusela ubushushu ngegesi ethintela umlilo eveliswa kukwanda ukuthintela ukusasazeka komlilo nokuthintela umonakalo kwizakhiwo xa kuvela umlilo.
Umgaqo
I-Ammonium polyphosphate isetyenziswa njengeyona nto iphambili ethintela umlilo kwiingubo ezithintela umlilo ezingaphakathi. I-Ammonium polyphosphate ineempawu ezilungileyo ezithintela umlilo. Xa ubushushu bunyuka, iya kubola ukuze ivelise i-phosphoric acid kunye negesi ye-ammonia. Ezi mveliso zinokunyibilikisa izinto eziphilayo zibe ngamalahle, ngaloo ndlela zigqume ioksijini kunye nobushushu, ngaloo ndlela zivelise isiphumo esithintela umlilo. Kwangaxeshanye, i-ammonium polyphosphate nayo iyanda. Xa ifudunyezwa kwaye ibolile, iya kuvelisa inani elikhulu legesi, ukuze ingubo ethintela umlilo engaphakathi yenze umaleko omkhulu wekhabhoni engatshiyo, ohlukanisa ngempumelelo umthombo womlilo ekudibaneni kwaye uthintele umlilo ukuba ungasasazeki.
Iingenelo
I-Ammonium polyphosphate ineengenelo zokuzinza kakuhle kobushushu, ukumelana namanzi nokufuma, ayinatyhefu kwaye ayingcolisi okusingqongileyo, ngoko ke isetyenziswa kakhulu kwiingubo ezingatshiyo ezingaphakathi. Ingongezwa kwizinto ezisisiseko zeengubo ezingatshiyo ukuze yenze inkqubo epheleleyo yengubo engatshiyo kunye nezinye izinto ezingatshiyo, izibopheleli kunye nezizalisi. Ngokubanzi, ukusetyenziswa kwe-ammonium polyphosphate kwiingubo ezingatshiyo ezingaphakathi kunokubonelela ngeempawu ezintle zokutsha komlilo kunye nokwandiswa, kwaye kukhuseleke ngokufanelekileyo ukhuseleko lwezakhiwo kunye nezakhiwo ezikumlilo.
Isicelo
Ngokweemfuno ezahlukeneyo zezixhobo kwi-APP, ukusetyenziswa kwe-ammonium polyphosphate ekugqumeni kubonakala kakhulu kwi:
1. I-Intumescent FR coating kwisakhiwo sentsimbi sokwakha ngaphakathi.
2. Ukwaleka ngasemva kwelaphu kumakhethini, ukwaleka okumnyama.
3. Intambo ye-FR.
4. Isetyenziswa kakhulu ekwakheni, kwiinqwelomoya, ekugqumeni umphezulu weenqanawa.
Umzekelo wefomyula yokugquma i-intumescent
