I-Ammonium polyphosphate (i-APP) yikhompawundi esetyenziswa kakhulu kwi-inorganic, eqondwa kuqala ngendima yayo njengento ebuyisela amadangatye kunye nesichumiso. Iimpawu zayo ezizodwa ziyenza ibe yinxalenye ebalulekileyo kwizicelo ezahlukeneyo, kubandakanya iiplastiki, amalaphu, kunye neengubo. Ukuqonda ukuzinza kwe-thermal ye-ammonium polyphosphate kubalulekile ekusebenziseni kwayo ngokufanelekileyo, ngakumbi kwiindawo ezinobushushu obuphezulu.
Ukuthotywa kwe-ammonium polyphosphate ngokuqhelekileyo kuqala kumaqondo obushushu aphakamileyo, ngokuqhelekileyo malunga nama-200 ukuya kuma-300 degrees Celsius (392 ukuya kuma-572 degrees Fahrenheit). Kula maqondo obushushu, i-compound ifumana uthotho lweenguqulelo zeekhemikhali ezinokukhokelela ekukhululweni kwe-ammonia kunye ne-phosphoric acid. Njengoko iqondo lokushisa linyuka ngakumbi, ngakumbi ngaphaya kwe-300 degrees Celsius, inkqubo yokuthotywa ikhawuleza, okubangelwa ukuchithwa kwesakhiwo sepolymeric ye-APP.
Ukuthotywa kwe-thermal ye-ammonium polyphosphate inokuphenjelelwa zizinto ezininzi, kubandakanywa ubunzima bayo bemolekyuli, ubukho bezongezo, kunye nokwakheka okuthe ngqo okusetyenzisiweyo. Umzekelo, ubunzima obuphantsi bemolekyuli ye-APP ithande ukuthotywa kumaqondo obushushu asezantsi xa kuthelekiswa nokwahluka okuphezulu kobunzima bemolekyuli. Ukongezelela, ubukho bezinye izinto kuqulunqo oludibeneyo lunokuphucula okanye luthintele inkqubo yokuthotywa, ngokuxhomekeke kwiipropati zabo ze-thermal kunye nokusebenzisana ne-APP.
Omnye wemiba ebalulekileyo ye-ammonium polyphosphate's thermal behaviour yindima yayo njengesithinteli somlilo. Xa ibonakaliswe kubushushu, i-APP inokukhulula iigesi ezingatshayo, ezinciphisa umphunga ovuthayo kwaye zincede ukucinezela ukutsha. Le propati ibaluleke kakhulu kwizicelo apho ukhuseleko lomlilo luyinkxalabo. Nangona kunjalo, ukusebenza kwe-APP njengesithinteli somlilo sibotshelelwe ngokusondeleyo kuzinzo lwayo lwe-thermal. Ukuba i-APP ithotywa ngokukhawuleza kakhulu, isenokunganikeli umgangatho ofunekayo wokhuseleko.
Ngaphezu koko, iimveliso zokuthotywa kwe-ammonium polyphosphate nazo zinokuchaphazela okusingqongileyo kunye nempilo yabantu. Ukukhutshwa kwe-ammonia, umzekelo, kunokufaka isandla kungcoliseko lomoya kwaye kunokubeka imingcipheko yempilo ukuba iphefumle kakhulu. Ngoko ke, ukuqonda iqondo lokushisa lokuthotywa kunye nokukhululwa okulandelayo kweegesi kubalulekile ekuhloleni ukhuseleko kunye nefuthe lokusingqongileyo kweemveliso eziqukethe i-APP.
Kwizicelo ezisebenzayo, kubalulekile ukuqwalasela iimeko zokusebenza kunye nokwenzeka kokuthotywa kwe-thermal xa usebenzisa i-ammonium polyphosphate. Abavelisi bahlala beqhuba uhlalutyo lwe-thermal, olufana nohlalutyo lwe-thermogravimetric (TGA), ukumisela amaqondo okushisa athile kunye nokwandisa ukwakhiwa kozinzo kunye nokusebenza.
Ukuqukumbela, i-ammonium polyphosphate iqala ukuthotywa kumaqondo obushushu amalunga nama-200 ukuya kuma-300 ngokukaCelsius, kunye nokuthotywa okubalulekileyo okwenzeka kumaqondo obushushu aphezulu. Uzinzo lwayo lwe-thermal luyinto ebalulekileyo ekusebenzeni kwayo njengento yokulahla ilangatye kunye nokusebenza kwayo ngokubanzi kwizicelo ezahlukeneyo. Ukuqonda ezi zakhiwo ze-thermal azincedi kuphela ekuphuhliseni iimveliso ezikhuselekileyo nezisebenzayo kodwa ziqinisekisa ukuthotyelwa kwemimiselo yokusingqongileyo kunye nempilo. Njengoko uphando luqhubeka, ulwazi olongezelelweyo malunga nokuziphatha kwe-thermal ye-ammonium polyphosphate iya kuphucula ukusetyenziswa kwayo kunye neeprofayili zokhuseleko kwishishini.
