1.Diammonium phosphate, inozivikanwawo sediammonium hydrogen phosphate (DAP), icompound fertilizer ine nitrogen ne phosphorus.Diammonium hydrogen phosphate ine huwandu hwakanyanya hwekukurumidza kuita fetiraiza.Chemicalbook inonyungudika zviri nyore mumvura uye ine nyaya isina kusimba mushure mekupera.Inokodzera marudzi ese embesa nevhu, kunyanya mbesa dzinoda nitrogen uye dzinoda phosphorus.Inogona kushandiswa se base fetireza kana topdressing, uye inokodzera kudzika kunyorera.
2.Diammonium phosphate inoreva chigadzirwa chemazuva ose, chine N18% uye p2o548%.Chimiro chekristaro chakati sandara uye oblique prism.Kunyungudika mumvura pa25 ℃ ndiyo 71%.Iyo pH yemhinduro yayo yakazara inosvika 8, iyo yakanyanya kukwirira kupfuura iyo ye monoammonium phosphate chemicalbook.Nekuda kwekuti iyo saturated solution yediammonium phosphate is alkaline, kuiisa kune ivhu rine acidic kunogona kuderedza kugadzika kwesimbi nealuminium paphosphorus, kuitira kuti phosphorus irambe ichishanda zvakanyanya.Saka, diammonium phosphate inokurudzirwa kuti ishandiswe muvhu rine acidic.
3.Colorless transparent monoclinic crystal kana white powder.Soluble mumvura, isinganyunguriki mudoro, acetone uye ammonia.
4.Parizvino, nzira huru dzekugadzirwa kwemaindasitiri dzinosanganisira thermal phosphoric acid uye extraction phosphoric acid, iyo inopindirana nemvura ammonia kuti ibudise diammonium hydrogen phosphate.Iyo yekare ine kuchena kwepamusoro uye iyo yekupedzisira ine mutengo wakaderera.Thermal phosphoric acid neutralization liquid ammonia nzira inonatsa iyo inopisa phosphoric acid nemvura yakanyungudutswa (mvura: phosphoric acid = 1.3:1) mu dilute phosphoric acid, pombi iyo muchikamu chekutanga tubular reactor kuti isaite neammonia, pomba mhinduro yemhinduro mune yechipiri. nhanho tubular reactor kuti uwedzere kuita neammonia, kuitira kuti pH kukosha kweiyo reverse chemicalbook reaction solution isvike pa8.0, wedzera arsenic kubvisa arsenic uye heavy metal inobvisa mumiriri kuchenesa mhinduro, sefa, uye kubvisa kusvibiswa senge arsenic nesimbi inorema, Iyo filtrate inotumirwa kune yakanaka gadziriso tank kuti igadzirise iyo pH kukosha kusvika 7.8 ~ 8.0, inotumirwa kune evaporator kuti ipfuure uye kutarisisa kune yakaenzana density ye1.3, inotumirwa kune inotonhorera crystallizer, yakatonhodzwa uye crystallized, centrifuged kuparadzanisa amai mvura. , uye yakaomeswa kuwana chigadzirwa chakapedzwa chediammonium hydrogen phosphate inodyiwa.Its h3po4+2nh3 → (NH4) 2HPO4 .
Application
1.Inoshandiswa sekuwedzera kwekudya, inodzoreredza murazvo uye mumiriri wekudzimisa moto muindasitiri.
2.Seye analytical reagent uye buffer, ndeyepamusoro-inoshanda fetiraiza yekunyorovesa mvura inoshandiswa zvakanyanya mumiriwo, michero, mupunga uye gorosi;Yeast food, etc.
3.Muindasitiri yechikafu, inoshandiswa sechikafu chinowedzera mumiririri, dovi regulator, yeast feed, uye yekuvirisa yekubatsira pakubika.Inogona kushandiswa sebhafa.
4.Sechikafu chemakemikaribook chinowedzera kune vanodya.
5.Inoshandiswa pakudhinda kweplate kugadzira, mushonga, kudzivirira moto, electronic tube nezvimwe zvinangwa.Fetereza giredhi rinonyanya kushandiswa seyakakwira nitrogen uye phosphorus compound fetereza.
6.Industrial giredhi rinoshandiswa impregnate huni uye machira kuwedzera kusimba kwavo;Inogona kushandiswa seyakaoma poda yekudzima moto mumiriri uye phosphorus yemarambi efluorescent;Inoshandiswawo mukudhinda nekugadzira ndiro, kugadzirwa kwemagetsi machubhu, ceramics, enamels, nezvimwewo, uye biochemical kurapwa kwetsvina;Flame retardant inoshandiswa semafuta ekudzivirira zvinhu zveroketi injini mota muindasitiri yemauto.
