Bright and healthy titanium consumer products
In 1795, the Austrian scientist M.A. Klaproth discovered a new element while studying rutile and named it after the Greek mythological figure Titans. This is where the name "titanium" comes from. In 1910, American chemist M.A. Hunter used sodium to reduce titanium tetrachloride to obtain relatively pure titanium; in 1932, Luxembourg scientist W.J. Kroll used tungsten to reduce titanium tetrachloride to obtain titanium; in 1940 , Kroll then used magnesium to reduce titanium tetrachloride under argon protection to obtain titanium, which laid the foundation for industrial titanium production since the 1970s.
Titanium easily reacts chemically with oxygen, nitrogen, hydrogen, water vapor, helium, carbon monoxide, carbon dioxide and other substances at high temperatures. Therefore, titanium can be used as a good getter. The surface of titanium can form a dense oxide film, which has a protective effect. Therefore, titanium has strong corrosion resistance in seawater, alkaline solutions, nitric acid, and aqueous chlorine. In dilute hydrochloric acid and dilute sulfuric acid with a concentration of less than 5%, titanium has a strong corrosion resistance. It also has certain corrosion resistance. Titanium hydride is very brittle and can be easily ground into powder. Titanium absorbs hydrogen within a certain temperature range and releases it when the temperature rises, making it a good hydrogen storage material.
The physical properties of titanium are closely related to its impurity content and types. Containing impurities oxygen, nitrogen, and carbon will increase its hardness, and iron will also reduce its corrosion resistance. Therefore, industrial titanium has strict requirements on its impurity content.
Advantages of titanium as a consumer product
Titanium is a biophilic metal and an excellent material for manufacturing civilian daily necessities. Although silver can also be used to make civilian daily necessities, the price of silver is higher than that of titanium, and its comprehensive performance is far inferior to titanium.
Titanium has many advantages in manufacturing civilian products:
Biophilia. Titanium is close to human bones, has good biocompatibility with human tissues, and has no toxic or side effects. At present, the annual growth rate of titanium alloy implants in global surgery is as high as approximately 15%.
No heavy metal pollution. The titanium content of industrial pure titanium is greater than 99%, containing only trace amounts of Fe, C, etc., and does not contain heavy metals such as Hg, Cr, As, Cd, etc. that are harmful to the human body. The content of other heavy metals is as low as 1/3 of the national standard. Even 1/10. Therefore, titanium has become an excellent material for manufacturing pots, water heaters, pots, cups and other household products, and is also an excellent material for preparing children's household products.
The antibacterial function is obvious. The oxide film on the surface of titanium can inhibit bacterial reproduction and growth, making it difficult for harmful bacteria to survive in titanium containers. Some titanium industry companies in China and Japan have developed titanium chopsticks, water cups, sports bottles, tea cups, wine glasses and other consumer products, which are deeply loved by consumers.
Lightweight and easy to carry. The density of titanium is 4.51g/cm3, which is smaller than that of stainless steel (7.8g/cm3). Therefore, the same volume of titanium is much lighter than stainless steel. Titanium kettles and other supplies are favored by outdoor sports enthusiasts due to their light weight and small size. favor.
Not easily deformed. The melting point of titanium is as high as 1667°C, and it can be used for a long time at high temperatures of 600°C without deformation, fatigue damage, or oxidation and shedding.
Excellent corrosion resistance and comprehensive performance. Titanium has good corrosion resistance, mechanical properties and process performance. In the production of chemicals, pharmaceuticals, alkali production, etc., titanium, as a corrosion-resistant material, can be used to replace stainless steel, nickel alloys and other rare metals. The use of titanium industrial equipment is of great significance to increase output, improve product quality, extend equipment service life, reduce production costs, prevent pollution, protect the environment, improve working conditions and increase productivity.
In 2021, there will be about 10 million titanium pots in China, each of which uses about 1kg of titanium material, that is, the amount of cold-rolled titanium strips will reach 10,000 tons; there will be about 11 million titanium water sets (cups, pots). If each water If the titanium material consumption is 0.3kg, the total titanium material consumption is about 3300 tons. Other titanium products such as tableware, cutlery, sports and outdoor products cannot be estimated.
