superphosphate. superphosphate los yog superphosphate ntawm txiv qaub, Ca (H2PO4)2, yog ib qho chaw tsim los ntawm kev kho pob zeb phosphate nrog sulfuric acid los yog phosphoric acid , los yog sib tov ntawm ob. Nws yog lub luag haujlwm tseem ceeb ntawm phosphate, daim ntawv ntawm phosphorus siv tau los ntawm cov nroj tsuag, thiab yog ib qho ntawm cov chiv tseem ceeb tshaj plaws hauv ntiaj teb.
Ntawm no, dab tsi yog cov tshuaj formula ntawm superphosphate?
Triple Super Phosphate (TSP) chiv yog tsim los ntawm inorganic as-ham uas yog siv los kho cov av Cheebtsam tseem ceeb rau kev ua liaj ua teb. TSP yog lub ntsiab lus ntawm triple superphosphate nrog tshuaj formula Ca (H2PO4). Qhov concentration ntawm P2O5 (PHOSPHATE) yog nyob ib ncig ntawm 44-46%.
Thib ob, triple superphosphate ua li cas? Cov neeg tsim khoom ua rau TSP feem ntau los ntawm kev ua haujlwm zoo hauv av phosphate pob zeb nrog kua phosphoric acid nyob rau hauv ib lub khob-hom tov khoom. Granular TSP yog ua zoo sib xws, tab sis qhov tshwm sim slurry yog sprayed li ib txheej rau me me hais los tsim granules ntawm qhov xav tau loj.
Hauv qhov no, dab tsi yog superphosphate?
Superphosphate yog tsim los ntawm reacting insoluble phosphate pob zeb nrog sulfuric acid los tsim ib tug sib tov ntawm soluble mono-calcium phosphate thiab calcium sulphate (kwv yees li 9% phosphorous) uas yog siv tau los ntawm cov nroj tsuag.
Dab tsi yog qhov txawv ntawm ib qho superphosphate thiab triple superphosphate?
Muaj Ib qho superphosphate (SSP) uas yog 20% Phosphate (7 mus rau 9% P) thiab muaj qhov tsim nyog ntawm Calcium thiab Sulphur, Ob chav Superphosphate (DSP) (17.1% P) thiab muaj Triple Superphosphate (TSP) uas muaj 48% Phosphate (20.7% P) tab sis muaj tsawg dua Sulfur thiab Calcium muaj.
