Wide application of titanium in various industries
Because of its high affinity for oxygen, titanium can form a dense oxide film on the surface, which can make the titanium element free from the medium, so it is particularly resistant to corrosion. Dititanium can form a passive oxide film on the surface in most aqueous solutions. Titanium can generate passive oxide film in acidic, alkaline, and salt solutions, so it has good stability, and has better corrosion resistance than stainless steel and other non-ferrous metals. Due to its excellent corrosion resistance and affinity, titanium , It is widely used in many industries.
1. Chemical Industry
Titanium materials have good stability in various acid, alkali, and salt media. For example, the use of titanium anodes and titanium wet chlorine coolers in the chlor-alkali industry has good economic effects.
2. Petroleum industry
Titanium has very strong stability among organic compounds. Therefore, titanium is an excellent structural material in petroleum refining and chemical industry, and can be used to make various titanium heat exchangers, titanium reactors, titanium high-pressure vessels and titanium distillation towers.
3. Metallurgical industry
(1) Titanium is an active metal with good gas absorption properties. It is an excellent degassing agent in the steelmaking industry. The oxygen and nitrogen that titanium can precipitate when the compound steel is cooled can make the steel tough and elastic. (2) Titanium has good corrosion resistance and stability in acidic solutions containing metal ions. Therefore, titanium electrolytic plates are used in the hydrometallurgical industry, such as the electrolytic production of non-ferrous metals such as copper, nickel, cobalt, and manganese. Has a very wide range of applications.
4. Chemical fertilizer industry
Urea is an important fertilizer. It is very corrosive under high temperature conditions. The use of titanium equipment can greatly increase the life of the equipment and greatly reduce the maintenance time. Therefore, the equipment in urea production uses titanium equipment.
5. Desalination and shipbuilding industry
Titanium has very good resistance to seawater corrosion, whether it is in static or high-speed flowing seawater, titanium has special stability. Therefore, titanium is an ideal material for seawater desalination equipment. Titanium is very resistant to corrosion by sea water and ocean air, and has high strength and light weight. It is an ideal structural material for the shipbuilding industry.
6. Power industry
Titanium has good stability in many corrosive hot water containing chlorides, sulfides, etc. After replacing copper-nickel alloy pipes with titanium pipes, the service life can be greatly increased, the maintenance time is reduced, and the economic effect is very significant.
7. Medical industry
Medical titanium materials can resist the corrosion of the human body, are harmless to the human body, have good biocompatibility and good comprehensive mechanical properties. So it is widely used in medical equipment and pharmaceutical industries, as well as human implants.
