New application of titanium alloy products such as titanium rod and titanium plate in industry

The notable feature of GR1 GR2 GR3 GR4 titanium sheet is its strong corrosion resistance. This is because it has a particularly high affinity for oxygen and can form a dense oxide film on its surface to protect titanium from medium corrosion. Metal titanium can form a passive oxide film on the surface in most aqueous solutions. Therefore, titanium has good stability in acidic, alkaline, neutral salt solution and oxidative medium, and its corrosion resistance is better than that of existing stainless steel and other non-ferrous metals, even comparable to platinum.

1. Chemical industry

Titanium is an excellent anti-corrosion material in the chemical industry, and it has been used more and more widely as it gets older. For example, the use of titanium metal anodes and titanium wet chlorine coolers in the chlor-alkali industry has received good economic results and is known as a revolution in the chlor-alkali industry.

2. Petroleum industry

Titanium has very good stability in organic compounds, except for the five organic acids (formic acid, acetic acid, oxalic acid, trichloroacetic acid and triacetic acid) at relatively high temperatures. Therefore, titanium is an excellent structural material in petroleum refining and petrochemical industry, and can be used to make various heat exchangers, reactors, high-pressure vessels and distillation towers.

3. Metallurgical industry

Titanium is an active metal with good gas absorption performance. It is an excellent paint remover in the steelmaking industry. It can combine oxygen and nitrogen precipitated by steel during cooling. Adding small amounts of titanium to steel makes it tough and resilient. Titanium is an important alloy additive in steelmaking, aluminum smelting and other industries. Titanium is widely used in the wet metallurgy industry, such as the electrolytic production of non-ferrous metals such as copper, nickel-cobalt, and manganese.

4. Chemical fertilizer industry

Urea is a very important chemical fertilizer, which is highly corrosive under high temperature and high pressure conditions in the production process. After replacing stainless steel with titanium, the service life of the equipment is greatly increased, and the maintenance time is greatly reduced. Therefore, the main equipment in urea production currently uses titanium.

5. Seawater desalination and shipbuilding industry

Titanium is highly resistant to seawater and ocean air corrosion, and has great strength and light weight. It is an ideal structural material for the shipbuilding industry and has been widely used in many parts of various ships.

1. Due to the high tensile strength and specific strength of titanium, the weight of the ship can be reduced. For example, according to design requirements, if it is a pure aluminum bottom plate, the thickness must reach 5mm. 1. The hull is light. The density of titanium is 4.5g/cm3, which is smaller than Fe7.9g/cm3. However, 2.5mm Ti is enough for a ship of the same size. The mass of the titanium hull is 30% FRP, which is 10% lighter than aluminum alloy. Since the surface of the titanium boat does not need to be sprayed with anti-rust paint, the quality of the paint is also saved. The shipboard engine may be miniaturized.

2. Speed increase. Due to the lightness of the ship. For a boat of the same shape, the engine of a titanium boat is 15% smaller than that of an aluminum alloy boat. With the same engine, the speed can be increased by 15%. In addition, there is no paint on the surface of the boat in direct contact with water, which also reduces the coefficient of friction with water, thereby increasing the speed of the boat. It also reduces the amount of CO2 produced.

3. Fuel costs and CO2 production are reduced. The light weight and high speed of the titanium ship greatly reduces the fuel cost per unit mass and unit voyage distance. It's not just a reduction in navigation costs. It is very effective in preventing global warming, which has become an international problem, but marine organisms are easy to attach to it.

4. Corrosion resistance. Titanium plates are as corrosion-resistant as stainless steel in seawater. Therefore, there is no need to spray anti-corrosion paint. FRP doesn't rust though. Difficult to remove. Aluminum alloy boats are easy to corrode, and they are also easy to adhere to marine organisms, which are difficult to remove. Therefore, the hull and bottom of FRP ships and Al alloy ships must be coated with anti-corrosion and anti-adhesion coatings for marine microorganisms. Compared with metals such as CuZn, Ti is not toxic, and marine organisms such as shellfish and seaweed are more likely to attach to titanium. When the boat is stationary, shellfish and seagrass grow very fast, but it does not corrode the titanium metal, and the surface is smooth and easy to peel off. Aquatic plants and shellfish attached to the propellers of the ship when the ship is stationary will fall off when the propellers rotate and rub against the water. Although titanium hardly requires anti-corrosion coatings, research on marine coatings for decoration and marking purposes should be carried out.

5. Recycling of waste ships. FRP ship waste is difficult to recycle. Waste products can be recycled and reused, which is beneficial to environmental protection.

6. Excellent stability. Titanium boats seldom roll longitudinally and laterally even in bad weather. Titanium boats seldom heel when navigating tight turns; oiling either side of the ship keeps balance without heeling. This is due to the titanium boat's light weight and low center of gravity. Titanium boats can sail stably even at high speeds.

6. Power industry

Titanium has good stability in many highly corrosive hot water containing chlorine compounds, sulfides, etc. Therefore, titanium has been widely used as cooling pipes for heat exchangers in thermal power plants, which greatly reduces maintenance time and is economical. The effect is very significant.

7. Paper and textile industry

Titanium has special corrosion resistance to chlorine dioxide, chlorous acid, chlorite and other bleaching agents. Therefore, titanium has an important application in the bleaching equipment of the textile printing and dyeing industry and the paper industry.

8. Medical and other aspects

Titanium products have good affinity and are harmless to the human body. Therefore, it can be widely used in various sectors of the medical and pharmaceutical industries. Grade 5 Titanium Sheet has good air absorption performance, and is also widely used in electronic vacuum technology and high vacuum technology.
