Qhov sib txawv tseem ceeb ntawm MAP thiab DAP chiv yog tias MAP chiv muaj txog 10% nitrogen, hos DAP chiv muaj txog 18% nitrogen.
MAP thiab DAP chiv yog hom ammonium chiv. Cov chiv no tau siv dav rau kev ua liaj ua teb raws li qhov chaw ntawm nitrogen thiab phosphorus. Phosphorous muaj nyob rau hauv daim ntawv ntawm P2O5, thaum nitrogen tshwm sim nyob rau hauv daim ntawv ntawm ammonium.
MAP Fertilizer yog dab tsi?
MAP chiv yog monoammonium phosphate chiv. Nws yog ib qho tseem ceeb hauv cov hom phiaj ua liaj ua teb raws li qhov chaw ntawm nitrogen thiab phosphorous. Cov tshuaj formula ntawm no compound yog NH4H2PO4. Nws muaj phosphorus nyob rau hauv daim ntawv ntawm P2O5. Qhov feem pua ntawm P2O2 hauv MAP chiv yog li 50% (feem ntau yog li ntawm 48 txog 61%). Tus nqi ntawm nitrogen tam sim no hauv MAP chiv yog li 10%. Cov chiv no muaj cov phosphorous ntau tshaj plaws piv rau lwm cov chiv muaj.
Kev tsim cov chiv MAP yog qhov yooj yim thaum piv rau lwm cov txheej txheem tsim cov chiv. Hauv cov txheej txheem tsim khoom no, ammonia thiab phosphoric acid yog reacted nrog ib leeg hauv qhov piv ntawm 1: 1. Cov tshuaj tiv thaiv no ua rau muaj slurry ntawm MAP chiv. Raws li cov kauj ruam tom ntej no, MAP slurry yog solidified nyob rau hauv ib tug granulator. Hauv lwm txoj hauv kev, MAP chiv yog tsim los siv ob qho khoom pib uas tau tsim los ua kom muaj kev sib haum xeeb hauv cov yeeb nkab-cross reactor. Cov tshuaj tiv thaiv no ua rau cov cua sov uas tso cai rau cov dej vaporizing tam sim no hauv cov tshuaj tiv thaiv sib tov, thiab tib lub sijhawm, cov khoom tsim tawm MAP yog solidified. Tseem muaj lwm txoj hauv kev uas tsis tshua muaj, thiab.
MAP chiv yog hom chiv. Nws yog cov khoom siv dej-soluble, thiab nws tuaj yeem yaj sai sai hauv cov av noo. Thaum dissolving hauv av dej, ob lub Cheebtsam nyob rau hauv cov chiv cais ntawm ib leeg, tso ammonium ions thiab phosphate ions. Ob qho ions no tseem ceeb hauv kev noj qab haus huv hauv av. Lub pH ntawm cov av yog 4-4.5 pH. Yog li, MAP fertilizer granules yog acidic, thiab nws ua rau cov chiv no zoo heev rau alkaline thiab nruab nrab pH av hom.
DAP Fertilizer yog dab tsi?
DAP chiv yog diammonium phosphate chiv. Qhov no yog hom chiv siv thoob plaws ntiaj teb. Piv nrog rau lwm hom chiv, DAP muaj cov ntsiab lus zoo heev. Cov tshuaj formula ntawm DAP fertilizer yog (NH4) 2HPO4. Cov chiv no muaj txog 18% nitrogen thiab 46% P2O5.
Thaum xav txog kev tsim cov chiv DAP, nws yog tsim nyob rau hauv cov tshuaj tiv thaiv ntawm ammonia thiab phosphoric acid. Nws tsim ib tug kub slurry uas yog ces txias rau granulation thiab sieving. DAP chiv yog cov dej-soluble heev thiab tsim cov tshuaj uas muaj li ntawm 7.5-8 pH tov thaum so.
Qhov txawv ntawm MAP thiab DAP Fertilizer yog dab tsi?
MAP thiab DAP chiv yog hom ammonium chiv. Cov chiv no tau siv dav rau kev ua liaj ua teb raws li qhov chaw ntawm nitrogen thiab phosphorus. Qhov sib txawv tseem ceeb ntawm MAP thiab DAP chiv yog MAP chiv muaj txog 10% nitrogen, thaum DAP chiv muaj txog 18% nitrogen. Ntxiv mus, MAP chiv muaj txog 50% phosphorus, whereas DAP chiv muaj txog 46% phosphorus.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm MAP thiab DAP chiv.
Summary – MAP vs DAP Fertilizer
MAP thiab DAP chiv yog hom ammonium chiv. Cov chiv no tau siv dav rau kev ua liaj ua teb raws li qhov chaw ntawm nitrogen thiab phosphorus. Qhov sib txawv tseem ceeb ntawm MAP thiab DAP chiv yog tias MAP chiv muaj txog 10% nitrogen, hos DAP chiv muaj txog 18% nitrogen.
