Nowadays, due to the continuous development and progress of social production level, the application of sulfur powder products in daily life is very extensive, and the prominent effect in the process of use is also very significant. The chemical properties of sulfur powder are more vivid, and it can form new compounds with various chemical substances, so it is widely used in agriculture, chemistry and other industries, which can reflect the value of sulfur powder.
The elemental sulfur in sulfur powder has oxidation and reduction properties, can react with iron to form ferrous sulfide, and can form sulfur hexafluoride with fluorine, and can form carbon dioxide with carbon at high temperature, except for the application in agriculture and chemical operations. In addition, sulfur powder has some value. The reaction of sulfur powder with chloral hydrate and ethanol can significantly affect the sleep of mice, and it has an effect on the control effect of chlorpromazine and thiopental sodium, and sulfur has a control effect on the brain stem.
At the same time, it can also be known that the sulfur powder can have a significant effect on the testicles of experimental mice in a suitable dose. Low-concentration sulfur can kill bacteria when it touches the skin, and combines with the microorganisms on the skin to form oxidized pentasulfuric acid. Sulfide can dissolve keratin and hair removal, and can be used as an adjuvant medicinal material for skin diseases. The use of sulfur soap can significantly reflect this application.
Sulfur powder is an important variety of inorganic pesticides. The product is light yellow solid or powder with obvious odor and can be volatile. Sulfur aqueous suspension is slightly acidic, insoluble in water, and reacts with alkali to form polysulfides.
When industrial sulfur is burned, it emits a cyan flame, and sulfur dioxide gas is produced along with the combustion. In production, sulfur is often processed into a colloidal suspension for pests and diseases, which is not easy to cause phytotoxicity to humans and animals. The industrial sulfur concrete is a thermoplastic material, and the construction method is completely different from that of ordinary concrete. It mainly adopts the heating pouring molding process. Sulfur should first be melted and dehydrated at a temperature of 130-150t, and then added to the powder; the aggregate should also be heated, generally not exceeding 60°C. The thickness of each layer of stones shall not exceed 40cm and pouring holes shall be reserved. The pouring process cannot be interrupted, and the horizontal construction joints of each layer should be exposed to stones so as to be joined with the previous layer.
