light pink monoclinic fine crystals. The relative density was 2. 95. Soluble in water, insoluble in ethanol. When heated above 200 ° C., the crystal water begins to be lost, and most of the crystal water is lost at about 280 ° C. At 700 ° C, an anhydrous salt melt is formed. 850 degrees began to decompose, due to different conditions and the release of sulfur trioxide, sulfur dioxide or oxygen, the residual black insoluble manganese tetroxide is completely decomposed at about 1150.

is one of the important trace element fertilizer, which can be used as base fertilizer, seed soaking, seed dressing, topdressing and foliar spraying, which can promote crop growth and increase yield. In animal husbandry and feed industry, used as feed additives, can make livestock and poultry develop well, and has the effect of fattening. It is also a raw material for processing paint and ink drying agent manganese naphthalate solution. It is used as a catalyst in the synthesis of fatty acids. In addition, it can also be used as raw materials for paper making, ceramics, printing and dyeing, ore flotation, electrolytic manganese production and other manganese salt production.
packed in woven bags lined with polyethylene plastic bags, each with a net weight of 50kg. Store in a ventilated, dry warehouse. Prevent weathering and moisture. Protection against rain and sun exposure during transport. When loading and unloading should be light to prevent packaging damage. The stacking height should be 5 packs. In case of fire, it can be suppressed by water, sand and all kinds of fire extinguishing. Toxicity and protection: see manganese metal.

Product description | Manganese sulfate (English: Manganese sulfate) is a light pink monoclinic fine crystal at room temperature. Soluble in water, insoluble in ethanol, heated to more than 200 ° C began to lose crystal water, about 280 ° C lost most of the crystal water, 700 ° C into anhydrous salt melt, 850 ° C began to decompose, sulfur trioxide, sulfur dioxide, or oxygen is released. manganese is an element of group VII of the periodic table of the elements, manganese is not found in the Free State in nature, and is generally present in animals and plants in the form of compounds. I have found that manganese is an essential trace element for animals, and a large number of studies have shown that manganese has an important nutritional role in the animal body. It is an important component of arginine kinase, proline peptidase, pyruvate, manganese ion and the role of activation of a variety of enzymes, is part of the hydrolase, de-slope enzyme. Activator of phosphorylase, ribozyme, etc. Manganese can promote growth, enhance immunity and improve animal reproductive performance. manganese sulfate is one of the important trace element fertilizers, which can be used as base fertilizer, seed soaking, seed dressing, topdressing and foliar spraying, which can promote the growth and increase the yield of crops. In animal husbandry and feed industry, used as feed additives, can make livestock and poultry develop well, and has the effect of fattening. Also processing paint, ink drying agent; Manganese acid solution of raw materials; Synthesis of fatty acids used as catalysts; In addition, can also be used for paper, ceramics, printing and dyeing, ore flotation; raw materials for the production of electrolytic manganese and other manganese salts.
