1.Diammonium phosphate, yomwe imadziwikanso kuti diammonium hydrogen phosphate (DAP), ndi feteleza wapawiri wokhala ndi nayitrogeni ndi phosphorous.Diammonium hydrogen phosphate ndi feteleza wochuluka wachangu.Chemicalbook imasungunuka mosavuta m'madzi ndipo imakhala ndi zinthu zochepa zolimba ikatha.Ndi yabwino kwa mitundu yonse ya mbewu ndi dothi, makamaka ku mbewu zomwe zimakonda nayitrogeni ndipo zimafuna phosphorous.Itha kugwiritsidwa ntchito ngati feteleza wapansi kapena ngati feteleza, ndipo ndiyoyenera kugwiritsa ntchito mozama.
2.Diammonium phosphate imatanthawuza chinthu chokhazikika, chomwe chili ndi N18% ndi p2o548%.Mawonekedwe a kristalo ndi osalala komanso oblique prism.Kusungunuka m'madzi pa 25 ℃ ndi 71%.PH ya yankho lake lodzaza imafika pa 8, yomwe ndi yokwera kwambiri kuposa ya monoammonium phosphate chemicalbook.Chifukwa yankho lodzaza la diammonium phosphate ndi lamchere, kuliyika ku dothi la acidic kumatha kuchepetsa kukhazikika kwa chitsulo ndi aluminiyamu pa phosphorous, kuti phosphorous ikhalebe yothandiza kwambiri.Chifukwa chake, diammonium phosphate imalimbikitsidwa kuti igwiritsidwe ntchito m'nthaka ya acidic.
3.Colorless transparent monoclinic crystal kapena ufa woyera.Kusungunuka m'madzi, osasungunuka mu mowa, acetone ndi ammonia.
4.Pakali pano, njira zazikulu zopangira mafakitale zimaphatikizapo kutentha kwa phosphoric acid ndi kutulutsa phosphoric acid, zomwe zimachita ndi ammonia yamadzimadzi kuti apange diammonium hydrogen phosphate.Yoyamba ili ndi chiyero chapamwamba ndipo yotsirizira ili ndi mtengo wotsika.Kutentha kwa phosphoric acid neutralization madzi ammonia njira kuchepetsa matenthedwe asidi phosphoric ndi madzi osungunuka (madzi: phosphoric acid = 1.3: 1) mu kuchepetsa phosphoric acid, kupopera mu gawo loyamba tubular riyakitala kuti neutralize ndi ammonia, mpope yankho anachita mu chachiwiri. siteji tubular riyakitala kuti achitenso ndi ammonia, kuti pH mtengo wa n'zosiyana chemicalbook anachita njira kufika pafupifupi 8.0, kuwonjezera arsenic kuchotsa wothandizila ndi heavy metal kuchotsa wothandizira kuyeretsa yankho, fyuluta, ndi kuchotsa zosafunika monga arsenic ndi zitsulo zolemera, Zosefera zimatumizidwa ku thanki yabwino yosinthira kusintha pH mtengo kukhala 7.8 ~ 8.0, kutumizidwa kwa evaporator kwa evaporator ndi ndende ku kachulukidwe wachibale wa 1.3, kutumizidwa ku crystallizer yozizira, utakhazikika ndi crystallized, centrifuged kupatutsa mayi wamadzimadzi. , ndi zouma kuti apeze chotsirizidwa cha edible diammonium hydrogen phosphate.h3po4+2nh3 yake → (NH4) 2HPO4 .
Kugwiritsa ntchito
1.Imagwiritsidwa ntchito ngati chowonjezera chakudya, choletsa moto komanso chozimitsa moto m'makampani.
2.Monga reagent analytical ndi buffer, ndizomwe zimafewetsa madzi a feteleza zomwe zimagwiritsidwa ntchito kwambiri mumasamba, zipatso, mpunga ndi tirigu;Chakudya cha yisiti, etc.
3.M'makampani azakudya, amagwiritsidwa ntchito ngati chowonjezera chakudya, chowongolera mtanda, chakudya cha yisiti, ndi chothandizira cha fermentation popanga moŵa.Itha kugwiritsidwa ntchito ngati buffer.
4.Monga chakudya cha chemicalbook chowonjezera cha zoweta.
5.Amagwiritsidwa ntchito posindikiza kupanga mbale, mankhwala, kupewa moto, chubu chamagetsi ndi zina.Feteleza kalasi zimagwiritsa ntchito monga mkulu ndende nayitrogeni ndi phosphorous pawiri fetereza.
6.Industrial giredi imagwiritsidwa ntchito kuyika matabwa ndi nsalu kuti ziwonjezere kukhazikika kwawo;Itha kugwiritsidwa ntchito ngati ufa wowuma wozimitsa moto ndi phosphorous wa nyali za fulorosenti;Amagwiritsidwanso ntchito posindikiza ndi kupanga mbale, kupanga machubu amagetsi, zoumba, ma enamel, etc., ndi mankhwala achilengedwe amadzi onyansa;Flame retardant yomwe imagwiritsidwa ntchito ngati zida zotenthetsera zamakina a roketi mumakampani ankhondo.
