I-1.I-Diammonium phosphate, eyaziwa ngokuba yi-diammonium hydrogen phosphate (DAP), isichumisi esine-nitrogen kunye ne-phosphorus.I-Diammonium hydrogen phosphate luxinaniso oluphezulu lwesichumiso esisebenza ngokukhawuleza.I-Chemicalbook inyibilika ngokulula emanzini kwaye inombandela omncinci oqinileyo emva kokuchithwa.Ilungele zonke iintlobo zezityalo kunye nemihlaba, ngakumbi kwizityalo ezithanda initrogen nedinga iphosphorus.Ingasetyenziswa njengesichumiso esisisiseko okanye i-topdressing, kwaye ifanelekile kwisicelo esinzulu.

I-2.I-Diammonium phosphate ibhekisela kwimveliso eqhelekileyo, equkethe i-N18% kunye ne-p2o548%.Ubume bekristale buthe tyaba kunye ne-oblique prism.Ukunyibilika emanzini kwi-25 ℃ yi-71%.I-pH yesisombululo sayo esigcweleyo ifikelela kwi-8, ephezulu kakhulu kunaleyo ye-monoammonium phosphate chemicalbook.Ngenxa yokuba isisombululo esigcweleyo se-diammonium phosphate si-alkaline, ukusisebenzisa kumhlaba omuncu kunokunciphisa ukulungiswa kwentsimbi kunye ne-aluminium kwi-phosphorus, ukuze i-phosphorus ihlale isebenza kakhulu.Ke ngoko, i-diammonium phosphate ikhuthazwa ukuba isetyenziswe kumhlaba oneasidi.

I-3.I-crystal monoclinic engabonakaliyo okanye i-powder emhlophe engenambala.Inyibilika emanzini, ayinyibiliki etywaleni, iacetone kunye neammonia.

I-4.Okwangoku, iindlela eziphambili zokuvelisa i-industrial zibandakanya i-thermal phosphoric acid kunye ne-extraction phosphoric acid, esabela nge-ammonia engamanzi ukuvelisa i-diammonium hydrogen phosphate.Owokuqala unobunyulu obuphezulu kwaye umva uneendleko eziphantsi.I-Thermal phosphoric acid neutralization liquid ammonia method dilute thermal phosphoric acid ngamanzi distilled (amanzi: phosphoric acid =1.3:1) kwi-dilute phosphoric acid, yimpompe kwinqanaba lokuqala lereactor ye-tubular ukuze ingathathi hlangothi nge-ammonia, ukumpompa isisombululo sokuphendula kwisibini. I-reactor ye-tubular yesiteji ukuze iqhubeke isabela nge-ammonia, ukwenzela ukuba ixabiso le-pH lesisombululo se-reverse chemicalbook reaction lifikelela malunga ne-8.0, yongeza i-agent yokususa i-arsenic kunye ne-ejenti yokususa isinyithi esinzima ukuhlambulula isisombululo, ukucoca, kunye nokususa ukungcola okufana ne-arsenic kunye neentsimbi ezinzima, Ifiltrate ithunyelwa kwitanki yohlengahlengiso ecolekileyo ukulungisa ixabiso le-pH ukuya kwi-7.8 ~ 8.0, ithunyelwe kwi-evaporator ukuze ibe ngumphunga kwaye igxininise kubuninzi be-1.3, ithunyelwe kwikristali yokupholisa, epholileyo kunye ne-crystallized, i-centrifuged ukwahlula ulwelo lukamama. , kwaye yomiswe ukufumana imveliso egqityiweyo ye-diammonium hydrogen phosphate etyiwayo.I-h3po4+2nh3 yayo → (NH4) 2HPO4.

Isicelo

I-1.Isetyenziswa njengezongezo zokutya, i-retardant yomlilo kunye ne-arhente yokucima umlilo kwishishini.
I-2.Njenge-reagent yokuhlalutya kunye ne-buffer, yinto ephezulu yokuthambisa amanzi yesichumisi esetyenziswa kakhulu kwimifuno, iziqhamo, irayisi kunye nengqolowa;Ukutya kwegwele, njl.
3.Kwishishini lokutya, isetyenziswa njenge-ejenti yokutya eninzi, isilawuli sentlama, i-yeast feed, kunye ne-fermentation encedisayo xa kusenziwa utywala.Ingasetyenziswa njengesithinteli.
4.Njengokongezwa kwencwadi yekhemikhali kwizetyisa.
I-5.Isetyenziselwa ukuprinta ukwenza ipleyiti, iyeza, ukuthintela umlilo, ityhubhu ye-elektroniki kunye nezinye iinjongo.Ibakala lesichumisi lisetyenziswa ikakhulu njengesichumiso esinenitrogen ephezulu kunye nephosphorus compound.
Ibakala 6.Industrial isetyenziselwa ukumilisela iinkuni kunye namalaphu ukwandisa ukuqina kwazo;Ingasetyenziswa njengomgubo owomileyo wokucima umlilo kunye ne-phosphorus kwizibane ze-fluorescent;Ikwasetyenziselwa ukuprinta kunye nokwenza iipleyiti, ukwenziwa kweetyhubhu ze-elektroniki, iiseramikhi, ii-enamels, njl., kunye nokunyangwa kwe-biochemical yamanzi amdaka;Iretardant yomlilo esetyenziswa njengesixhobo sokufakelwa kwe-thermal ye-rocket injini kwishishini lomkhosi.
