Sulfur is an important chemical raw material, and the fertilizer industry is the largest user of sulfur. Other uses of sulfur include explosives, steel pickling, pharmaceutical and food industry, safety stripping, water treatment, rubber, electrolysis industry, catalyst, pigment, paper, chemical industry Products, sulfur cement, sulfur concrete, alcohols, adhesives, pesticides, rail anchors, black gunpowder, firecrackers, etc.
Sulfur powder, with a content of 99.5%-99.95%, has industrial grade, refined grade, rubber grade and insoluble sulfur, etc. The general product fineness has different specifications such as 200 mesh, 325 mesh, 400 mesh and 500 mesh. Light yellow powder, packaged in a net weight of 25KG or 40KG per bag, the outer layer is a plastic-coated woven bag and the inner layer is a plastic bag.
Sulfur powder has many uses, and is mostly used in rubber tires, chemical fibers, pesticides, dyes, paper, medicine, sugar, pesticides and chemical industries. In the electronics industry, various phosphors are used in the manufacture of TV picture tubes and other cathode ray tubes, and the vulcanizing agent in rubber is also a high-level chemical reagent. Sulfur can be used to make industrial sulfuric acid. In the production of insecticides and fungicides, it can be used in the pharmaceutical industry to produce sulfonamide and other drugs, in the military, it can be used in the production of conventional explosives, and in the food industry, it can be used in the production of sucrose decolorizers, etc. It also has a certain role in the semiconductor industry. It is selectively toxic to fungal spores of the powdery mildew family and has been used for many years as a protective fungicide against this family of diseases. Sulfur is also selectively toxic to mites, so it is also commonly used to kill mites. As a flammable solid, sulfur is mainly used in the manufacture of sulfuric acid, dyes and rubber products, as well as in pharmaceuticals, pesticides, matches, gunpowder and industrial ceramics, auxiliary materials for building materials and other industrial sectors. It must be used with caution in horticultural soil improvement, paying attention to pollution and safety issues.
The main use of sulfur is the manufacture of sulfuric acid. With the rapid development of acid-consuming industries such as fluorine chemicals, citric acid, and titanium dioxide, in addition to the manufacture of phosphate fertilizer products, the proportion of sulfur that is converted into sulfuric acid and used in the production of other chemical and industrial products is increasing. high. For example, it is used in the leaching of rocks containing metals, in the production of agrochemicals, in the production of plastics and synthetic rubber, in the production of pulp and paper, and in the production of general chemicals.
