I-Ammonium Polyphosphate (APP)
I-Ammonium Polyphosphate (i-APP) yinto eqhelekileyo esetyenziswa kwi-flame retardant, esetyenziswa ngokubanzi kwiingubo zokuvala umlilo ze-intumescent.I-intumescent i-retardant ye-coat retardant yi-coat ekhethekileyo yokuthintela umlilo.Umsebenzi wayo ophambili kukwenza umaleko wokugquma ubushushu ngokusebenzisa irhasi ye-flame retardant eveliswa kukwandiswa ukuthintela ukusasazeka komlilo nokuthintela umonakalo kwizakhiwo xa umlilo usenzeka.
Umgaqo
I-Ammonium polyphosphate isetyenziswa njengeyona nto ithintela idangatye kwiingubo ezikwaziyo ukumelana nomlilo.I-Ammonium polyphosphate ineempawu ezilungileyo zokunqanda umlilo.Xa iqondo lobushushu linyuka, liya kubola livelise i-asidi ye-phosphoric kunye negesi ye-ammonia.Ezi mveliso zinokukhupha amanzi kwi-organic matter zibe ngamalahle, ngaloo ndlela zigqume ioksijini kunye nobushushu, ngaloo ndlela zivelise isiphumo sokubuyiswa komlilo.Ngexesha elifanayo, i-ammonium polyphosphate nayo iyanda.Xa ishushu kwaye ibolile, iya kuvelisa isixa esikhulu segesi, ukwenzela ukuba i-intumescent ifake i-fireproof ifake i-carbon layer engenamlilo, eyahlula ngokufanelekileyo umthombo womlilo ekudibaneni kunye nokuthintela umlilo ukuba usasazeke.
Iingenelo
I-Ammonium polyphosphate ineenzuzo zokuzinza okuhle kwe-thermal, ukuxhathisa kwamanzi kunye nokufuma, okungeyona ityhefu kunye nokungangcolisi kwendalo, ngoko ke isetyenziswa ngokubanzi kwiingubo ze-intumescent ezingenamlilo.Inokongezwa kwisiseko sezinto zokugquma umlilo ukuze zenze inkqubo yokugquma i-fire retardant epheleleyo kunye nezinye i-flame retardants, i-binders kunye ne-fillers.Ngokubanzi, ukusetyenziswa kwe-ammonium polyphosphate kwi-intumescent i-retardant ye-retardant inokubonelela ngeempawu ezibalaseleyo zomlilo kunye neempawu zokwandisa, kunye nokukhusela ngokufanelekileyo ukhuseleko lwezakhiwo kunye nezakhiwo emlilweni.
Isicelo
Ngokwemathiriyeli eyahlukeneyo ifuna kwi-APP, Ukusetyenziswa kwe-ammonium polyphosphate ekugqumeni kubonakaliswa ikakhulu kwi:
1. Ukugquma kwe-Intumescent FR kwisakhiwo sensimbi yokwakhiwa kwangaphakathi.
2. I-Textile back coating in curtains, blackout coating.
3. Intambo yeFR.
4. Ubukhulu obusetyenziswa kulwakhiwo, ukubhabha, ukugquma komphezulu weenqanawa.
Umzekelo wefomula yokwaleka intumescent
