1.I-Diammonium phosphate, eyaziwa nangokuthi i-diammonium hydrogen phosphate (DAP), ingumanyolo oyinhlanganisela oqukethe i-nitrogen ne-phosphorus.I-Diammonium hydrogen phosphate iyinhlanganisela ephezulu yomanyolo osebenza ngokushesha.I-Chemicalbook incibilika kalula emanzini futhi inento eqinile kancane ngemva kokuhlakazeka.Ilungele zonke izinhlobo zezitshalo kanye nenhlabathi, ikakhulukazi izitshalo ezithanda i-nitrogen futhi ezidinga i-phosphorus.Ingasetshenziswa njengomanyolo oyisisekelo noma i-topdressing, futhi ifanele ukusetshenziswa okujulile.
I-2.I-Diammonium phosphate ibhekisela kumkhiqizo ojwayelekile, oqukethe i-N18% ne-p2o548%.I-crystal shape iyisicaba futhi i-oblique prism.Ukuncibilika emanzini ku-25 ℃ kungu-71%.I-pH yesisombululo sayo esigcwele ifinyelela ku-8, ephakeme kakhulu kunaleyo ye-monoammonium phosphate chemicalbook.Ngenxa yokuthi isixazululo esigcwele se-diammonium phosphate sine-alkaline, ukusisebenzisa enhlabathini ene-asidi kunganciphisa ukumiswa kwensimbi ne-aluminium ku-phosphorus, ukuze i-phosphorus ihlale isebenza kakhulu.Ngakho-ke, i-diammonium phosphate inconywa ukuthi isetshenziswe enhlabathini ene-asidi.
I-3.I-crystal esobala ye-monoclinic engenambala noma impushana emhlophe.Incibilika emanzini, ayincibiliki otshwaleni, i-acetone ne-ammonia.
I-4.Okwamanje, izindlela eziyinhloko zokukhiqiza izimboni zihlanganisa i-thermal phosphoric acid kanye ne-extraction phosphoric acid, esabela nge-ammonia ye-liquid ukukhiqiza i-diammonium hydrogen phosphate.Owokuqala unokuhlanzeka okuphezulu futhi okugcina kunezindleko eziphansi.I-Thermal phosphoric acid neutralization liquid ammonia indlela yokunciphisa i-phosphoric acid eshisayo ngamanzi acwecwe (amanzi: i-phosphoric acid =1.3:1) ibe yi-phosphoric acid ehlanjululwe, uyipompela esigabeni sokuqala se-tubular reactor ukuze unciphise nge-ammonia, futha isisombululo sokusabela kwesibili. i-reactor ye-tubular yesiteji ukuze iqhubeke isabele nge-ammonia, ukuze inani le-pH lesixazululo se-reverse chemicalbook reaction lifinyelele cishe ku-8.0, engeza i-arsenic ejenti yokususa kanye ne-ejenti yokususa insimbi esindayo ukuze kuhlanzwe ikhambi, isihlungi, futhi kususe ukungcola okunjenge-arsenic nezinsimbi ezisindayo, I-filtrate ithunyelwa ethangini elihle lokulungiswa ukuze kulungiswe inani le-pH libe ngu-7.8 ~ 8.0, ithunyelwe ku-evaporator ukuze ihwamuke futhi igxiliswe kubuningi obuhlobene obungu-1.3, ithunyelwe ku-crystallizer epholile, epholile futhi efakwe ikristalu, i-centrifuged ukuze ihlukanise uketshezi lukamama. , futhi omisiwe ukuze kutholwe umkhiqizo oqediwe we-diammonium hydrogen phosphate edliwayo.I-h3po4+2nh3 → (NH4) 2HPO4 yayo.
Isicelo
1.Isetshenziswa njengesengezo sokuphakelayo, iretardant flame kanye ne-ejenti yokucisha umlilo embonini
2.Njenge-reagent ne-buffer yokuhlaziya, iyisithambisi samanzi sikamanyolo esisebenza kahle kakhulu esisetshenziswa kakhulu emifino, izithelo, irayisi nokolweni;Ukudla kwemvubelo, njll.
3.Embonini yokudla, isetshenziswa njenge-ejenti yokugcwalisa ukudla, isilawuli senhlama, isifunzo semvubelo, kanye nensiza yokuvutshelwa ukuze kutshalwe.Ingasetshenziswa njenge-buffer.
4.Njengesengezo se-chemicalbook feed for ruminants.
I-5.Isetshenziselwa ukuphrinta amapuleti okwenza, imithi, ukuvimbela umlilo, ishubhu ye-electronic nezinye izinjongo.Ibanga likamanyolo lisetshenziswa kakhulu njengomanyolo ohlanganisa i-nitrogen ne-phosphorus.
Ibanga le-6.Industrial isetshenziselwa ukufaka ukhuni nezindwangu ukwandisa ukuqina kwazo;Ingasetshenziswa njenge-ejenti yokucima umlilo yempuphu eyomile kanye ne-phosphorus yezibani ze-fluorescent;Ibuye isetshenziselwe ukuphrinta nokwenza amapuleti, ukwakhiwa kwamashubhu kagesi, izitsha zobumba, okoqweqwe lwawo, njll., kanye nokwelashwa kwamanzi angcolile kwamakhemikhali ezinto eziphilayo;I-flame retardant esetshenziswa njengezinto ezishisayo zokufakwa kwe-rocket injini embonini yezempi.
