I-Ammonium polyphosphate (APP) yinto esetyenziswa ngokubanzi i-flame retardant kunye nesichumisi, eyaziwayo ngokusebenza kwayo ekwandiseni ukumelana nomlilo kwizinto ezahlukeneyo. Enye yeendlela ezibalulekileyo zohlalutyo ezisetyenzisiweyo ukuqonda iimpawu ze-thermal ze-APP yi-Thermogravimetric Analysis (TGA). I-TGA ilinganisa utshintsho kubunzima bento njengoko ifudunyezwa, ipholiswa, okanye igcinwa kwiqondo lobushushu elingaguqukiyo, ibonelela ngezimvo ezixabisekileyo kuzinzo lwayo lwe-thermal, ukuziphatha kokubola, kunye nokusebenza ngokubanzi kwizicelo.
Ukubaluleka kwe-TGA kuphononongo lwe-ammonium polyphosphate ayinakugqithiswa. Okokuqala nokuphambili, i-TGA inceda ekumiseleni ukuzinza kwe-thermal ye-APP. Ukuqonda uluhlu lobushushu apho i-APP ihlala izinzile kubalulekile kwisicelo sayo ekubambeni komlilo. Ukuba i-APP ibola kumaqondo obushushu asezantsi, isenokungasebenzi ekukhuseleni imathiriyeli emlilweni, njengoko ingaphulukana neempawu zayo zokukwazi ukumelana namadangatye phambi kokuba imathiriyeli ngokwayo ifikelele kubushushu obubalulekileyo. I-TGA ivumela abaphandi ukuba bachonge ukuqala kokubola, ukubavumela ukuba basebenzise imixube yezicelo ezithile.
Ngaphezu koko, i-TGA ibonelela ngemibono kwiimveliso zokubola ze-APP. Ukutshatyalaliswa kwe-thermal ye-ammonium polyphosphate kunokukhokelela ekukhululweni kweegesi ezahlukeneyo, kuquka i-ammonia kunye ne-phosphoric acid. Ngokuhlalutya ilahleko enkulu kwizigaba ezahlukeneyo zeqondo lokushisa, abaphandi banokuchonga uluhlu oluthile lweqondo lokushisa apho ezi gesi zikhutshwa khona. Olu lwazi lubalulekile ekuqondeni indlela yokunqandwa komlilo, njengoko ukukhutshwa kweegesi ezingatshayo kunokunciphisa umphunga ovuthayo kunye nokunciphisa ukutsha ngokubanzi kwezinto.
Omnye umba obalulekileyo we-TGA yindima yayo ekuqulunqweni kwe-APP-based composite. Kwizicelo ezininzi, i-APP idityaniswa nezinye izixhobo zokuphucula ukusebenza kwayo. I-TGA ingasetyenziselwa ukuvavanya ukuhambelana kunye nokuzinza kwezi zixhobo phantsi koxinzelelo lwe-thermal. Ngokuphonononga ukuziphatha kwe-thermal yemathiriyeli edibeneyo, abaphandi banokumisela umlinganiselo ofanelekileyo we-APP kwamanye amacandelo, ukuqinisekisa ukuba imveliso yokugqibela igcina iipropati zayo zokunqanda amadangatya ngelixa ifezekisa iimpawu ezifunekayo zoomatshini kunye ne-thermal.
Ngaphaya koko, i-TGA inokunceda ekulawuleni umgangatho ngexesha lemveliso ye-ammonium polyphosphate. Ngokuseka iphrofayili ye-thermal ye-APP, abavelisi banokubeka iliso ukuhambelana kunye nomgangatho weemveliso zabo. Ukuphambuka kwindlela yokuziphatha ye-thermal emiselweyo kunokubonisa imiba kwinkqubo yokuvelisa, njengokuphendula okungaphelelanga okanye ukungcoliswa, okunokuthi kuphazamise ukusebenza kwe-flame retardant.
Ukuqukumbela, ukubaluleka kwe-TGA kuphononongo lwe-ammonium polyphosphate kumandla ayo okubonelela ngolwazi olubalulekileyo malunga nokuzinza kwe-thermal, ukuziphatha kokubola, kunye nokuhambelana nezinye izinto. Obu buchule bokuhlalutya abuphuculi nje ukuqonda kwethu ukusebenza kwe-APP njengento ethintela amadangatya kodwa ikwadlala indima ebalulekileyo kuphuhliso nolawulo lomgangatho weemveliso ezisekwe kwi-APP. Njengoko amashishini aqhubeka efuna izisombululo ezisebenzayo zokhuseleko lomlilo, ulwazi olufunyenwe kwi-TGA luya kuhlala luxabiseke kakhulu ekuqhubeleni phambili ukusetyenziswa kwe-ammonium polyphosphate kwiinkalo ezahlukeneyo.
