sulfur, chemical formula S, is a light yellow brittle crystal or powder, has a special odor, insoluble in water, slightly soluble in ethanol, ether, soluble in carbon disulfide. It is an important chemical raw material and pesticide raw materials, widely used in rubber, pesticides, matches, fireworks, fertilizers and paper and other industries. In the rubber industry, sulfur is used as a vulcanizing agent, which can form cross-linking bonds between rubber molecular chains and improve the strength and wear resistance of rubber; in the pesticide industry, sulfur is an important raw material for the manufacture of pesticides and fungicides; in addition, Sulfur is also used to make matches and fireworks, as a fertilizer additive to increase the sulfur content of the soil, and used in the bleaching and deinking processes of the paper industry. As a multifunctional chemical raw material, sulfur is widely used in industrial production.
(1) Sulfur has a wide range of applications in the chemical industry. It is an important raw material for the manufacture of sulfur dyes, matches, sulfuric acid, pesticides and chemical fibers. At the same time, sulfur is also a vulcanizing agent in the rubber industry, which can enhance the elasticity and wear resistance of rubber, and improve the hardness and high temperature resistance of rubber.
(2) Sulfur also plays an important role in the field of agriculture. It can be used as a raw material for pesticides to control crop diseases and insect pests. Sulfur has the characteristics of sterilization and insecticidal, which can effectively control the bacteria and insect pests on crops and protect the healthy growth of crops. In addition, sulfur can also be used as a soil conditioner to change the pH and fertility of the soil.
(3) Sulfur also has unique value in the field of medicine. It is a commonly used antibacterial agent and can be used to treat various skin diseases, such as eczema, acne and ringworm. The antibacterial and antifungal properties of sulfur make it an ideal pharmaceutical ingredient for killing germs and fungi. In addition, sulfur can also be used as a preservative in some medical procedures to protect instruments from bacterial contamination.
(4) Sulfur is also widely used in other fields. For example, in the metallurgical industry, sulfur can be used to extract useful elements in metal ores; it also plays an important role in battery manufacturing, pigment production and gunpowder preparation. In addition, sulfur is also a raw material for riveting railway cement sleepers and insulating electrical appliances, and is a good insulator for heat and electricity.

is yellow or light yellow solid. It is easy to burn, the combustion temperature is generally 248~261 ℃, and sulfur dioxide is produced during combustion. Soluble in carbon disulfide, carbon tetrachloride and benzene, slightly soluble in ethanol and ethers, insoluble in water. Electrical and thermal conductivity are poor. Liquid sulfur can dissolve hydrogen sulfide, and its solubility increases with the increase of temperature, and hydrogen sulfide can be precipitated when the temperature decreases.
Industrial sulfur is heated, added to remove arsenic and heavy metal agent for refining, grinding and sieving to obtain food grade sulfur.
The sulfur content (S) of this product shall not be less than 98.0%.
is used in the food industry for preservation, insecticide, bleaching, etc. Our regulations are limited to fumigation products.
GRAS (FDA,§ 184. 3826,2000). Long-term inhalation of sulfur dust, prone to fatigue, headache, dizziness, indigestion and other symptoms. The staff should be well protected. Sulfur dust is explosive, 850tim sulfur dust will explode when the concentration is greater than 2. 3g/m3. The powdered sulfur shall be stored in a ventilated and dry warehouse. Bulk, granular and flaky sulfur can be stored in open or indoor warehouses. Keep away from heat sources and kindling seeds, and do not store and mix with charcoal, acids and oxidants. Due to the precipitation of hydrogen sulfide in liquid sulfur, the vent above the storage tank must be kept unblocked during storage and transportation to avoid the accumulation of hydrogen sulfide and explosion. Sulfur powder should not be affected with damp. When loading and unloading, handle with ease to prevent moisture due to damaged packaging. In case of fire, fog water, sand and carbon dioxide can be used to put out the fire. Powder in the air or when mixed with oxidant prone to combustion, and even explosion. Non-toxic.
