| high concentration of water-soluble phosphate fertilizer | heavy superphosphate, also known as three phosphorus fertilizer, heavy calcium, is a high concentration of water-soluble phosphate, the content of effective phosphorus P2O5 is between 36% and 50%, and the appearance is light gray particles or powder. The main component is water-soluble Monocalcium phosphate as calcium superphosphate, without calcium sulfate, containing 4%~ 8% of free phosphoric acid, acidic, powder is easy to absorb moisture, easy to knot block, corrosive, the industry will be made into granular, in order to improve the physical properties, it is not easy to absorb moisture and not easy to agglomerate after being made into granules, which is convenient for storage and transportation. heavy superphosphate is obtained by decomposing phosphate rock with phosphoric acid. The phosphoric acid can be derived from both wet and thermal processes. When the impurities such as iron, aluminum, magnesium and manganese contained in phosphate rock and phosphoric acid raw materials are too high, The product will bond; The concentration of iron and aluminum ions in wet-process phosphoric acid is too high, it will reduce the activity of hydrogen ions in phosphoric acid, thus reducing the ability of phosphoric acid to decompose phosphate rock. Therefore, In general, phosphate rock is required to produce heavy superphosphate more than superphosphate. Should not be mixed with alkaline, otherwise it will reduce the effectiveness of phosphorus. |
| calcium superphosphate | calcium superphosphate is a porous acidic chemical phosphate fertilizer, which is prepared by the reaction of phosphate rock with dilute sulfuric acid, the main component is Monocalcium phosphate, phosphorus content is 16%- 18%, secondary component is calcium sulfate, its weight is about 50%, low phosphorus content, more secondary components. At room temperature for gray-white to dark gray powder, corrosive and moisture absorption , often contact with humid air easy to moisture absorption and caking, such as long storage time, part of the water-soluble phosphorus will change into poorly soluble phosphorus, and the higher the humidity and temperature, the faster the species transformation rate. superphosphate is a water-soluble phosphate fertilizer, which can be used as basal fertilizer, early topdressing or root-external topdressing, and contains a large amount of calcium sulfate, Application in sulfur-deficient soil has the role of supplementary sulfur nutrition, suitable for all kinds of crops, more suitable for alkaline soil, slightly alkaline soil and neutral soil, not with lime, straw ash and other alkali fertilizer mixed application. Not only can promote the growth and development of crops, but also can make plants enhance disease resistance, drought resistance, early maturity, not easy to lodging, cotton, sugar beet, sugar cane, wheat has a significant effect on increasing yield. |
| thermal method and wet process for phosphoric acid production | thermal method yellow phosphorus is prepared by reacting phosphate rock with Coke in an electric furnace, phosphorus pentoxide gas is produced by melting and combustion of yellow phosphorus, and then phosphoric acid is obtained by absorption with water. The phosphate rock powder is decomposed with excess sulfuric acid, and the slurry containing phosphoric acid and gypsum is obtained in the reaction tank, and the solid phosphogypsum is removed by vacuum filtration, the filtered liquid is the dilute phosphorus acid. The thermal process consumes more electricity in the production of yellow phosphorus, so the production cost of phosphoric acid is higher. Most domestic heavy superphosphate manufacturers use wet process to produce phosphoric acid. |
| application method | heavy superphosphate is suitable for various soils and crops, and can be used as basal fertilizer, topdressing and compound (mixed) fertilizer raw materials. Widely used in rice, wheat, corn, sorghum, cotton flowers, fruits, vegetables and other food crops and cash crops; Widely used in red soil, yellow soil, brown soil, yellow soil, black soil, cinnamon soil, purple soil, albic soil and other all kinds of soil, especially suitable for China's northwest, north China, Northeast and other arid areas with little rain. The application method was the same as that of superphosphate. Since the phosphorus content of the heavy calcium is relatively high, the application amount is less than that of the superphosphate. Because the heavy superphosphate does not contain gypsum with sulfur component, the application effect on sulfur-like crops, such as potato, leguminous and ten flower family crops, is under the condition of equal phosphorus, not as much as superphosphate. Should not be used to dip the root, should not be used for seed dressing. For acidic soil, lime is best applied once a few days before application. |
| Use | for economic crops, vegetables, base fertilizer and topdressing of fruit trees and ornamental plants |
