I-Ammonium polyphosphate (APP) yinxalenye esetyenziswa kakhulu kwi-inorganic compound, eyaziwa kakhulu ngendima yayo njengesithinteli-langatye kunye nesichumisi. Iimpawu zayo ezikhethekileyo zenza ukuba ibe yinxalenye ebalulekileyo kwizicelo ezahlukeneyo, kubandakanya iiplastiki, amalaphu, kunye neengubo. Ukuqonda ukuzinza kobushushu be-ammonium polyphosphate kubalulekile ekusetyenzisweni kwayo ngokufanelekileyo, ngakumbi kwiindawo ezinobushushu obuphezulu.
Ukuwohloka kwe-ammonium polyphosphate kudla ngokuqala kumaqondo obushushu aphezulu, ngokubanzi malunga nama-200 ukuya kuma-300 degrees Celsius (392 ukuya kuma-572 degrees Fahrenheit). Kula maqondo obushushu, i-compound idlula kuthotho lweenguqu zeekhemikhali ezinokukhokelela ekukhutshweni kwe-ammonia kunye ne-phosphoric acid. Njengoko amaqondo obushushu enyuka ngakumbi, ngakumbi ngaphaya kwama-300 degrees Celsius, inkqubo yokuwohloka iyakhawuleza, nto leyo ekhokelela ekuqhekekeni kwesakhiwo se-polymeric se-APP.
Ukuwohloka kobushushu be-ammonium polyphosphate kunokuchatshazelwa zizinto ezahlukeneyo, kubandakanya ubunzima bayo be-molecular, ubukho bezongezo, kunye nohlobo oluthile olusetyenzisiweyo. Umzekelo, ubunzima obuphantsi be-molecule APP budla ngokuwohloka kubushushu obuphantsi xa kuthelekiswa nobunzima obuphezulu be-molecular. Ukongeza, ubukho bezinye izinto kwi-composite formulation bunokuphucula okanye buthintele inkqubo yokuwohloka, kuxhomekeke kwiimpawu zazo zobushushu kunye nokusebenzisana ne-APP.
Enye yezinto ezibalulekileyo kwindlela esebenza ngayo i-ammonium polyphosphate kubushushu yindima yayo njenge-retardant yelangatye. Xa ibekwe kubushushu, i-APP inokukhupha iigesi ezingenakutsha, ezinciphisa umphunga ovuthayo kwaye zincede ekuthinteleni ukutsha. Le propati ibaluleke kakhulu kwiindawo apho ukhuseleko lomlilo luyinkxalabo. Nangona kunjalo, ukusebenza kakuhle kwe-APP njenge-retardant yelangatye kunxulunyaniswa ngokusondeleyo nokuzinza kwayo kubushushu. Ukuba i-APP yonakala ngokukhawuleza, isenokungaboneleli ngenqanaba lokhuseleko elifunekayo.
Ngaphezu koko, iimveliso zokubola kwe-ammonium polyphosphate zinokuba nefuthe kwindalo esingqongileyo nakwimpilo yabantu. Umzekelo, ukukhululwa kwe-ammonia kunokubangela ungcoliseko lomoya kwaye kunokubangela iingozi kwimpilo ukuba kuphefumlwa ngobuninzi. Ke ngoko, ukuqonda ubushushu bokonakala kunye nokukhululwa kweegesi okulandelayo kubalulekile ekuvavanyeni ukhuseleko kunye nempembelelo kwindalo kwiimveliso ezine-APP.
Kwizicelo ezisebenzayo, kubalulekile ukuqwalasela iimeko zokusebenza kunye namathuba okuwohloka kobushushu xa usebenzisa i-ammonium polyphosphate. Abavelisi badla ngokwenza uhlalutyo lobushushu, olufana nohlalutyo lwe-thermogravimetric (TGA), ukumisela amaqondo obushushu athile okuwohloka kunye nokuphucula iindlela zokwenziwa ukuze zihlale zizinzile kwaye zisebenze kakuhle.
Ukuqukumbela, i-ammonium polyphosphate iqala ukonakala kumaqondo obushushu amalunga nama-200 ukuya kuma-300 degrees Celsius, apho ukonakala okukhulu kwenzeka kumaqondo obushushu aphezulu. Uzinzo lwayo lobushushu luyinto ebalulekileyo ekusebenzeni kwayo njenge-anti-flame retardant kunye nokusetyenziswa kwayo ngokubanzi kwizicelo ezahlukeneyo. Ukuqonda ezi mpawu zobushushu akuncedi nje kuphela ekuphuhlisweni kweemveliso ezikhuselekileyo nezisebenzayo kodwa kuqinisekisa ukuthotyelwa kwemigaqo yokusingqongileyo kunye nempilo. Njengoko uphando luqhubeka, ukuqonda okungakumbi malunga nokuziphatha kobushushu kwe-ammonium polyphosphate kuya kuphucula ukusetyenziswa kwayo kunye neeprofayili zokhuseleko kushishino.
