Calcium Dihydrogen Phosphate Raw Materials Powder
Product Overview:
Superphosphate is a loose and porous acidic chemical phosphate fertilizer, which is made by the reaction of phosphate rock powder with dilute sulfuric acid. The main component is monocalcium phosphate, with a phosphorus content of 16%-18%. The secondary component is calcium sulfate, which accounts for about 50% by weight. It has a low phosphorus content and more secondary components. It is an off-white to dark gray powder at room temperature. It is corrosive and hygroscopic. It is easy to absorb moisture and agglomerate when in contact with humid air. If it is stored for a long time, part of the water-soluble phosphorus will be converted into insoluble phosphorus. The higher the humidity and temperature, the faster the conversion rate.

Calcium Dihydrogen Phosphate Raw Materials Powder Details
Calcium Dihydrogen Phosphate Powder Usage and Synthesis.
Heavy superphosphate is considered a top-quality phosphate fertilizer. It is suitable for various food crops and cash crops such as rice, wheat, corn, sorghum, cotton, fruits, and vegetables. It is suitable for various soil types such as red soil, yellow soil, brown soil, yellow tidal soil, black soil, brown soil, purple soil, and white pulp soil. It is especially suitable for use in phosphorus-deficient areas such as North my country, Northeast China, and Northwest China.
However, the long-term application of heavy superphosphate will naturally lead to sulfur deficiency. Acidic soils in the south are prone to sulfur deficiency, and sulfur-loving plants such as onions and garlic vegetables are prone to sulfur deficiency. The symptoms of crop sulfur deficiency are similar to those of nitrogen deficiency, and the main feature is the loss of green and yellowing of leaves, but from a subtle performance point of view, there is a difference.
Uses and functions of Calcium Dihydrogen Phosphate.
It can be used as topdressing, basal fertilizer or seed fertilizer for crops, supplying plants with phosphorus, calcium, sulfur and other elements, and improving alkaline soil. It can be used as basal fertilizer, foliar topdressing, and foliar spraying. When mixed with nitrogen fertilizer, it has the effect of nitrogen fixation and reduces nitrogen loss. It can promote plant germination, root growth, branching, fruiting and maturity, and can be used as a raw material for the production of compound fertilizers.
Pharmacological effects of Calcium Dihydrogen Phosphate.
Product method of Bulk Calcium Dihydrogen Phosphate Powder.
Dissolve calcium hydrogen phosphate for feed in dry heat phosphoric acid, control the pH value at about 3.2 to generate calcium dihydrogen phosphate, add arsenic removal agent and heavy metal removal agent, filter, concentrate, cool and crystallize, centrifuge and dry to obtain calcium dihydrogen phosphate for feed.
