It is usually used as a standard nitrogen fertilizer, nitrogen content is between 20% to 30%. In the 1960s, Ammonium sulfate is the main variety of nitrogen fertilizer, but also is a major source to provide crop nutrients sulfur. Firstly ammonia and sulfuric acid was neutralized to obtain, but later increasing proportion of by-product ammonium sulfate, and now basically all domestic-product is from byproduct of other industries, such as coking industry, caprolactam, sulfuric acid tail gas desulfurization, desulfurization of power plant, acrylonitrile and methyl methacrylate, zinc oxide. By-product ammonium sulfate followed the principle of " waste control by waste ", to achieve the comprehensive utilization of waste, to achieve energy saving purposes. Especially with the breakthrough technology of ammonia desulfurization project, by-product ammonium sulfate production of power plant desulfurization will increase substantially in the future. Pure product of ammonium sulfate is white crystals, heated to 100 ℃ , began to be decomposed into ammonia and ammonium bisulfate, a by-product with a yellowish or gray, small moisture absorption, easy to agglomerate, it is easier to save and easily soluble in water, insoluble ethanol and acetone. Usage: 1. Mainly used as fertilizer, for various soil and crop. 2. For the analysis reagents, also for protein precipitation. 3. Used as a flux, fabric fire agent, etc. 4. Used as a fertilizer, also can be used as flux, fire retardant fabric, as the salting-out agent, osmotic pressure regulating agents in medicine. 5. Used as raw materials of hydrogen peroxide , ammonium chloride, ammonium alum and production in chemical industry, as a flux in the welding industry. As a fire retardant in textile fabric industry. As a plating bath additives in electroplating industry. As a nitrogen fertilizer in agriculture, for general soil and crops. As a dough modifier, yeast nutrients in food grade product. 6. Dough modifier; yeast nutrients. Used as nitrogen source of yeast culture in fresh yeast used production, the dosage is not specified. As yeast nutrients in bread, the amount is about 10% (approximately 0.25% of the amount of wheat flour). As a processing aid listed in GB 2760-90. Application methods: (1) as base fertilizer. When ammonium sulfate as base fertilizer should be deep application and earthing to facilitate crop uptake. (2) as a topdressing. This is the most appropriate method of application. The amount of ammonium sulfate fertilizer is determined according to the different soil types. For poor performance of retaining water and fertilizer of soil, topdressing by stage, the amount of each time should not be excessive; For good performance of retaining water and fertilizer of soil, the amount of each time may be suitable to be more. How much soil moisture has a greater impact on fertilizer, especially in dry land, when applied ammonium sulfate must pay attention to timely watering. As for as topdressing in paddy fields, it should first drain off to dry, and pay attention to combine with used reciprocating simultaneously. In addition, there are also obvious differences when applied ammonium sulfate on different crops, such as for fruit trees, can be ditching for drill fertilization, circulating fertilization or hole fertilization. (3) more suitable as seed fertilizer. Because ammonium sulfate has no adverse effects on seed germination. |
