Characteristics of Sodium Fluoride Titanium Oxide Sulfate

Titanium oxysulfate is a colorless cubic or tetragonal crystal. Sensitive to moisture. Solubility in water (g/100ml): 4 at 15 ℃, 4.3 at 25 ℃, 5 at 100 ℃, insoluble in ethanol. Partial hydrolysis of aqueous solution results in alkaline reaction. The pH of the newly prepared saturated solution is 7.4. Its aqueous solution can make glass fuzz, but its dried crystals or powder can be stored in glass bottles. The relative density is 2.78. Melting point 993 ℃. Boiling point is 1695 ℃. Moderate toxicity, median lethal dose (rat, oral) 0.18g/kg. Has strong irritability.

A typical chemical plant is a sulfuric acid plant established in England in the 1840s. It first uses sulfur as raw material, and then uses pyrite as raw material. The products are mainly used to produce nitric acid, hydrochloric acid, and drugs, but the output was not large at that time. During the Industrial Revolution, the textile industry developed rapidly. It, along with industries such as glass and soap, used a large amount of alkali. Under the bounty of the College of Plant Alkali and Natural Alkali Science, it obtained salt as raw material to build a factory and produce sulfuric acid, which also drove the development of the sulfuric acid (one of the raw materials) industry; The hydrogen chloride generated during production is used to produce hydrochloric acid, chlorine gas, bleaching powder, and other urgently needed substances in the industry. Soda ash can also be causticized to fully utilize both raw materials and by-products; The filling device for absorbing hydrogen chloride, the rotary furnace for calcining raw materials and semi-finished products, as well as equipment for concentration, crystallization, filtration, etc., have gradually been applied to other chemical enterprises, laying the foundation for chemical unit operations

1. When feeding, the lower the moisture content of the product, the better. If the moisture content is more than 9%, it will cause poor feeding.

2. The hydrochloric acid in the product must be cleaned thoroughly, otherwise it will corrode the equipment and cause the dried product to turn yellow.

3. The dust collection device needs to be equipped with a cooling device. Only after cooling can the moisture content of the product be reduced to less than 0.5%, which can improve the quality of the product.

In the coating industry, it is used as a phosphating accelerator to stabilize the phosphating solution, refine the phosphating process, and improve the performance of the phosphating film. The sealing of Al3+, which has a highly harmful negative catalytic effect, in the phosphating of aluminum and its alloys enables the smooth progress of phosphating as a wood preservative, agricultural insecticide, brewing fungicide, pharmaceutical preservative, soldering flux, alkaline zinc salt zinc plating additive, enamel, paper industry, etc.
