1.Diammonium phosphate, tseem hu ua diammonium hydrogen phosphate (DAP), yog cov chiv chiv uas muaj nitrogen thiab phosphorus.Diammonium hydrogen phosphate yog ib qho muaj zog ntawm cov chiv ua kom nrawm.Chemicalbook yog yooj yim soluble nyob rau hauv dej thiab muaj tsawg dua cov khoom tom qab dissolution.Nws yog qhov tsim nyog rau txhua hom qoob loo thiab av, tshwj xeeb tshaj yog rau cov qoob loo uas nyiam nitrogen thiab xav tau phosphorus.Nws tuaj yeem siv los ua cov chiv hauv paus lossis topdressing, thiab nws yog qhov tsim nyog rau daim ntawv thov sib sib zog nqus.
2.Diammonium phosphate yog hais txog cov khoom txheem, uas muaj N18% thiab p2o548%.Cov khoom siv lead ua yog tiaj tus thiab oblique prism.Solubility hauv dej ntawm 25 ℃ yog 71%.Cov pH ntawm nws cov tshuaj saturated ncav cuag 8, uas yog ntau dua li ntawm monoammonium phosphate chemicalbook.Vim hais tias cov tshuaj saturated diammonium phosphate yog alkaline, thov nws rau acidic av yuav txo tau cov fixation ntawm hlau thiab txhuas ntawm phosphorus, yog li ntawd phosphorus tseem zoo heev.Yog li ntawd, diammonium phosphate tau tawm tswv yim los siv rau hauv cov av acidic.
3.Colorless pob tshab monoclinic siv lead ua los yog hmoov dawb.Soluble hauv dej, insoluble hauv cawv, acetone thiab ammonia.
4.Tam sim no, cov txheej txheem tseem ceeb ntawm kev tsim khoom muaj xws li thermal phosphoric acid thiab extraction phosphoric acid, uas ua rau cov kua ammonia los tsim diammonium hydrogen phosphate.Cov qub muaj siab purity thiab tom kawg muaj tus nqi qis.Thermal phosphoric acid neutralization kua ammonia txoj kev dilute lub thermal phosphoric acid nrog dej distilled (dej: phosphoric acid = 1.3: 1) rau hauv dilute phosphoric acid, tso nws mus rau hauv thawj theem tubular reactor rau neutralize nrog ammonia, tso cov tshuaj tiv thaiv rau hauv qhov thib ob. theem tubular reactor ntxiv reactor nrog ammonia, yog li ntawd tus nqi pH ntawm cov ntaub ntawv rov qab cov tshuaj tiv thaiv cov tshuaj tiv thaiv mus txog 8.0, ntxiv arsenic tshem tawm tus neeg saib xyuas thiab hnyav hlau tshem tawm tus neeg saib xyuas kom huv si, lim, thiab tshem tawm impurities xws li arsenic thiab hnyav hlau, Cov lim dej xa mus rau lub tank hloov kho kom zoo los kho tus nqi pH mus rau 7.8 ~ 8.0, xa mus rau lub evaporator rau evaporation thiab concentration mus rau qhov txheeb ze ntom ntom ntawm 1.3, xa mus rau lub txias crystallizer, txias thiab crystallized, centrifuged cais niam kua. , thiab qhuav kom tau cov khoom tiav ntawm diammonium hydrogen phosphate edible.H3po4+2nh3 → (NH4) 2HPO4 .
Daim ntawv thov
1.Nws yog siv los ua khoom noj additive, nplaim hluav taws thiab tua hluav taws hauv kev lag luam
2.As ib qho tshuaj reagent thiab tsis, nws yog ib tug high-efficiency fertilizer dej softener lug siv nyob rau hauv zaub, txiv hmab txiv ntoo, mov thiab nplej;Cov khoom noj poov xab, thiab lwm yam.
3.Hauv kev lag luam khoom noj khoom haus, nws yog siv los ua zaub mov bulking tus neeg saib xyuas, ua khob noom cookie regulator, poov xab pub, thiab fermentation pab rau brewing.Nws tuaj yeem siv los ua qhov tsis muaj.
4.Raws li pub chemicalbook additive rau ruminants.
5.Nws yog siv rau kev luam ntawv phaj, tshuaj, tiv thaiv hluav taws, hluav taws xob raj thiab lwm yam.Cov qib chiv feem ntau yog siv los ua siab concentration nitrogen thiab phosphorus compound fertilizer.
6.Industrial qib yog siv los impregnate ntoo thiab fabrics kom lawv durability;Nws tuaj yeem siv ua hmoov qhuav tua hluav taws thiab phosphorus rau cov teeb fluorescent;Nws kuj yog siv rau hauv kev luam ntawv thiab phaj ua, kev tsim cov raj hluav taws xob, ceramics, enamels, thiab lwm yam, thiab kev kho biochemical ntawm cov dej khib nyiab;Cov nplaim hluav taws kub hnyiab tau siv los ua cov khoom siv thermal rwb thaiv tsev ntawm lub foob pob hluav taws lub cev muaj zog hauv kev lag luam tub rog.
