I-Ammonium polyphosphate (APP) sisichumisi esithintela ilangatye esisetyenziswa kakhulu, esaziwa ngokusebenza kwayo kakuhle ekuphuculeni ukumelana nomlilo kwizinto ezahlukeneyo. Enye yeendlela ezibalulekileyo zohlalutyo ezisetyenziswa ukuqonda iipropati zobushushu ze-APP yiThermogravimetric Analysis (TGA). I-TGA ilinganisa utshintsho kubunzima bento njengoko ishushu, ipholiswa, okanye igcinwe kubushushu obungaguqukiyo, inika ulwazi oluxabisekileyo malunga nokuzinza kwayo kubushushu, indlela yokubola, kunye nokusebenza ngokubanzi kwizicelo.
Ukubaluleka kwe-TGA kuphononongo lwe-ammonium polyphosphate akunakugxininiswa kakhulu. Okokuqala, i-TGA inceda ekumiseleni uzinzo lobushushu lwe-APP. Ukuqonda uluhlu lobushushu apho i-APP ihlala izinzile kubalulekile ekusetyenzisweni kwayo xa kuncitshiswa umlilo. Ukuba i-APP iyabola kumaqondo obushushu aphantsi, isenokungasebenzi ekukhuseleni izinto emlilweni, njengoko ingalahlekelwa ziimpawu zayo ezithintela umlilo ngaphambi kokuba izinto ngokwazo zifikelele kubushushu obubalulekileyo. I-TGA ivumela abaphandi ukuba bachonge ukuqala kokubola, nto leyo ebenza bakwazi ukwenza ngcono iifomyula kwizicelo ezithile.
Ngaphezu koko, i-TGA inika ulwazi ngeemveliso zokubola kwe-APP. Ukuwohloka kobushushu be-ammonium polyphosphate kunokukhokelela ekukhutshweni kweegesi ezahlukeneyo, kuquka i-ammonia kunye ne-phosphoric acid. Ngokuhlalutya ukulahleka kobunzima kumanqanaba obushushu ahlukeneyo, abaphandi banokuchonga uluhlu oluthile lobushushu apho ezi gesi zikhutshwa khona. Olu lwazi lubalulekile ekuqondeni indlela yokuthintela ilangatye, njengoko ukukhutshwa kweegesi ezingatshiyo kunokunciphisa umphunga otshayo kwaye kunciphise ukutsha ngokubanzi kwezinto.
Enye into ebalulekileyo ye-TGA yindima yayo ekwakhiweni kwezinto ezidityanisiweyo ezisekelwe kwi-APP. Kwizicelo ezininzi, i-APP idityaniswe nezinye izinto ukuphucula ukusebenza kwayo. I-TGA ingasetyenziselwa ukuvavanya ukuhambelana kunye nokuzinza kwezi zinto zidityanisiweyo phantsi koxinzelelo lobushushu. Ngokuvavanya ukuziphatha kobushushu bezinto ezidityanisiweyo, abaphandi banokumisela umlinganiselo ofanelekileyo we-APP kwezinye izinto, ukuqinisekisa ukuba imveliso yokugqibela igcina iimpawu zayo ezithintela umlilo ngelixa ifezekisa iimpawu ezifunwayo zoomatshini kunye nobushushu.
Ngaphezu koko, i-TGA inokunceda ekulawuleni umgangatho ngexesha lokuveliswa kwe-ammonium polyphosphate. Ngokuseka iprofayili yobushushu ye-APP, abavelisi banokujonga ukuhambelana kunye nomgangatho weemveliso zabo. Ukuphambuka kwindlela yokuziphatha kobushushu esele imiselwe kunokubonisa iingxaki kwinkqubo yemveliso, ezifana neempendulo ezingaphelelanga okanye ungcoliseko, olunokuphazamisa ukusebenza kwe-flame retardant.
Ukuqukumbela, ukubaluleka kwe-TGA kuphononongo lwe-ammonium polyphosphate kukwikhono layo lokubonelela ngolwazi olubalulekileyo malunga nokuzinza kobushushu, indlela yokubola, kunye nokuhambelana nezinye izinto. Le ndlela yokuhlalutya ayiphuculi nje kuphela ukuqonda kwethu ukusebenza kwe-APP njengento ethintela ilangatye kodwa ikwadlala indima ebalulekileyo ekuphuhlisweni nasekulawulweni komgangatho weemveliso ezisekelwe kwi-APP. Njengoko amashishini eqhubeka nokufuna izisombululo ezisebenzayo zokhuseleko lomlilo, ulwazi olufunyenwe kwi-TGA luya kuhlala lubaluleke kakhulu ekuphuculeni ukusetyenziswa kwe-ammonium polyphosphate kwiinkalo ezahlukeneyo.
ISichuan Taifeng New Flame Retardant Co., LtdNgumvelisi onamava angama-22 eminyaka egxile ekuveliseni izinto ezithintela ilangatye ze-ammonium polyphosphate, kwaye iimveliso zethu zithunyelwa kwamanye amazwe.
ummeli wethu ilangatye retardantTF-241ilungele indalo kwaye iyabiza, inokusetyenziswa ngokuvuthiweyo kwi-PP, PE, HEDP.
