1.Diammonium phosphate, kuma aka sani da diammonium hydrogen phosphate (DAP), wani fili ne taki dauke da nitrogen da phosphorus.Diammonium hydrogen phosphate shine babban taro na taki mai saurin aiki.Littafin sinadarai yana da sauƙin narkewa a cikin ruwa kuma yana da ƙarancin ƙarfi bayan rushewa.Ya dace da kowane nau'in amfanin gona da ƙasa, musamman ga amfanin gona masu son nitrogen kuma suna buƙatar phosphorus.Ana iya amfani da shi azaman taki mai tushe ko sutura, kuma ya dace da aikace-aikacen zurfi.
2.Diammonium phosphate yana nufin samfurin daidaitaccen samfurin, wanda ya ƙunshi N18% da p2o548%.Siffar crystal ɗin lebur ce kuma baƙar fata.Solubility a cikin ruwa a 25 ℃ shine 71%.PH na cikakken maganin sa ya kai 8, wanda ya fi na littafin sinadarai na monoammonium phosphate yawa.Saboda cikakken bayani na diammonium phosphate shine alkaline, yin amfani da shi a cikin ƙasa mai acidic zai iya rage gyare-gyaren ƙarfe da aluminum akan phosphorus, don haka phosphorus ya kasance mai tasiri sosai.Don haka, ana ba da shawarar yin amfani da diammonium phosphate a cikin ƙasa mai acidic.
3.Colorless m monoclinic crystal ko farin foda.Mai narkewa a cikin ruwa, mai narkewa a cikin barasa, acetone da ammonia.
4.A halin yanzu, manyan hanyoyin samar da masana'antu sun hada da thermal phosphoric acid da kuma cire phosphoric acid, wanda ke amsawa tare da ammonia na ruwa don samar da diammonium hydrogen phosphate.Na farko yana da babban tsarki kuma na baya yana da ƙananan farashi.Thermal phosphoric acid neutralization ruwa ammonia Hanyar tsarma thermal phosphoric acid da distilled ruwa (ruwa: phosphoric acid = 1.3: 1) a cikin dilute phosphoric acid, zuba shi a cikin mataki na farko tubular reactor don neutralize da ammonia, famfo da dauki bayani a cikin na biyu. matakin tubular reactor don ƙara amsawa tare da ammonia, don haka ƙimar pH na juyawar maganin maganin sinadarai ya kai kusan 8.0, ƙara wakili mai cire arsenic da wakili mai cire ƙarfe mai nauyi don tsarkake maganin, tace, da cire ƙazanta kamar arsenic da ƙarfe masu nauyi, Ana aika filtrate zuwa tankin daidaitawa mai kyau don daidaita ƙimar pH zuwa 7.8 ~ 8.0, aika zuwa evaporator don evaporation da maida hankali ga ƙarancin dangi na 1.3, aika zuwa crystallizer mai sanyaya, sanyaya da crystallized, centrifuged don raba uwar ruwa. , da kuma bushe don samun ƙãre samfurin dimmonium hydrogen phosphate ci.H3po4+2nh3 → (NH4) 2HPO4 .
Aikace-aikace
1.An yi amfani da matsayin abinci ƙari, harshen wuta retardant da wuta extinguishing wakili a masana'antu
2.As an analytical reagent da buffer, shi ne wani high-inganci taki ruwa softener yadu amfani da kayan lambu, 'ya'yan itatuwa, shinkafa da alkama;Abincin yisti, da sauransu.
3.A cikin masana'antar abinci, ana amfani da shi azaman wakili na bulking abinci, mai sarrafa kullu, abinci mai yisti, da ƙari na fermentation don shayarwa.Ana iya amfani da shi azaman buffer.
4.A matsayin abincin sinadarai ƙari ga naman dabbobi.
5.An yi amfani da shi don buga farantin karfe, magani, rigakafin wuta, bututun lantarki da sauran dalilai.Ana amfani da darajar taki a matsayin babban taro nitrogen da takin mai magani na phosphorus.
6.Industrial sa ake amfani da su impregnate itace da yadudduka don ƙara su karko;Ana iya amfani da shi azaman busassun foda mai kashe wuta da phosphorus don fitilu masu kyalli;Ana kuma amfani da ita wajen bugu da yin faranti, kera bututun lantarki, yumbu, enamels, da dai sauransu, da kuma sarrafa kwayoyin halitta na ruwa;An yi amfani da mai ɗaukar harshen wuta azaman kayan kariyar zafi na injin roka a masana'antar soji.
