Talk about the application of titanium materials in various fields!

更新时间  2023-01-07 11:42:08

Titanium is widely used in many fields because of its good corrosion resistance, mechanical properties and technological properties. In chemical production, titanium is used to replace stainless steel, nickel base alloy and other rare metals as corrosion resistant materials, which is significant for improving quality, prolonging service life of equipment, reducing consumption, reducing energy consumption, reducing cost, avoiding pollution, improving working conditions and increasing productivity. In recent years, the range of titanium materials used in chemical industry has been expanding, and the consumption has increased year by year, which is one of the main anti-corrosion materials in equipment. As a corrosion resistant structural material used in chemical plants, titanium has established its position, and as a material in chemical equipment, titanium has attracted more and more attention of engineers and technicians.

(1) Chlor alkali industry

Chlor alkali industry is an important basic raw material industry, and its production and development have a great impact on the national economy. This is because the titanium material has good corrosion resistance to chloride ions. At present, titanium is widely used in chlor alkali industry to manufacture metal anode electrolyzer, separator, refined brine preheater, etc. In the past, the main components of these equipment were mostly made of non-metallic materials, which were inferior to the mechanical properties, thermal stability and processing technology of non-metallic materials, resulting in bulky equipment, large energy consumption, short service life and environmental pollution.

(2) Soda industry

Soda ash is one of the basic chemical raw materials, which is directly related to the economic development. In the production process of soda ash, the gas medium is mostly NH3 and CO2, and the liquid medium is mainly NaC1, NH4C1, NH4HCO3 and solutions with high C1 concentration. The main equipment such as carbonization tower tubes, hot mother liquor coolers, coolers, and crystallization external coolers used for carbonation reaction are not corrosion resistant, with serious corrosion leakage, and their service life should not exceed three years.
