In today's more and more attention to health, titanium as a normal metal has entered thousands of households, closely related to people's lives, but do you truly understand titanium?
Titanium is a relatively recent discovery. In 1791, an Englishman named Gregor discovered titanium while studying ilmenite and rutile, but he didn't name the metal. In 1795, the German chemist Kraprote, in his research, rediscovered and named the new element Titanium, referring to the Titans of Greek mythology. It was not until 1910 that American chemist Hunter used sodium reduction to produce titanium with a purity of 99.9%.
Seamless titanium tube manufacturer say The industrial application of titanium metal was after World War II. Industrial production of titanium began in 1947 in the United States using the magnesium reduction process. Our country has long recognized the importance of titanium in the strategic field. In 1954, we began titanium research and development. In 1959, the first batch of titanium ingot was produced at Fushun Aluminum Plant. Our country has established a complete industrial chain of titanium, and has become the first country in the world in titanium production. Fang Yi, former Vice Premier of The State Council, wrote an inscription for the titanium industry, "Rare metals are the most valuable and have a more brilliant strategic future."
Titanium is not scarce on Earth. It ranks fourth in reserves after aluminum, iron and magnesium, but it is so difficult to extract and process that it is called a rare metal. At present, only four countries in the world have the whole industrial chain of titanium metal production, namely China, the United States, Russia and Japan. It can be seen that the amount of titanium consumption and the development level of titanium industry of a country are critical indicators to measure a country's comprehensive national strength. Titanium metal has corrosion resistance, elevated melting point, great strength and additional characteristics, is widely used in aviation, aerospace, medical, electronic and other fields, known as the "third metal", "ocean metal" and "space metal".
China is extremely wealthy in titanium resources with the world's top reserves, and the Panxi region is the region with the most abundant titanium resources, accounting for 93% of the country's total reserves. Known as the "vanadium titanium city" of Panzhihua local titanium ore resources mainly used in the production of titanium dioxide, this is an essential basic raw material of the chemical industry, mainly used in the production of coatings, paint, textile, etc., we brush the wall of huge white powder is the main component of titanium dioxide, so titanium is not strange in our life, but why there are still the vast majority of people only heard of titanium, Without knowing its close connection to our healthy life?
In the medical field, titanium metal has excellent affinity and biocompatibility, so it can grow together with the human body without rejection. It is the best implant material. At present, 90% of implant materials in the medical field are made of titanium. For example, titanium bone plates, bone nails, spine nails, etc., with them, patients do not need to take out a second operation, so that patients do not have to suffer a second time. At the same time, titanium 3D printing has transformed the field of traditional medicine, reducing the cost of manufacturing tiny batches of orthopedic implants and saving more patients. Titanium also plays an irreplaceable role in dental implants, hip joints, heart bypass, cranial reconstruction and more.
In the industrial field, titanium metal has excellent corrosion resistance and can play an irreplaceable role in the fields of chlor-alkali, salt chemical industry, nitric acid production, electrolytic copper and so on. Before in some chemical field anticorrosive equipment is made of stainless steel, and in the strong corrosion environment, the general ordinary steel equipment will be damaged in about half a year, stainless steel equipment will leak in about 2-3 years, and the design life of the equipment made of titanium metal can reach more than 30 years, in today's stage of environmental protection and equipment safety more and more attention, Titanium equipment has been widely used in petroleum, chemical and environmental protection equipment, and the titanium used in such equipment has accounted for more than 60% of the domestic titanium production.
In the military field, titanium is the first to be applied in the military field, especially in the aviation and aerospace field. Titanium has become one of the most influential materials in the military and national defense field by making full use of its advantages of light weight, great strength and corrosion resistance. To measure the advanced nature of an aircraft, the amount of titanium is used in the field of materials. For example, the amount of titanium used in international civil airliners typically exceeds 10%, and the amount of titanium used in military fighter jets typically exceeds 15%. For example, the amount of titanium used in F35 fighter jets in the United States reaches 30%, and the amount of titanium used in F22 stealth fighter jets exceeds 40%. Our C919 jumbo jet uses 6 tons of titanium and J-20 uses 25% of titanium.
In the field of architecture, the entire shell of China National Grand Theater is made of titanium metal, which shines brightly on the sun. In addition, Jiangsu Grand Theater, Hangzhou Grand Theater and other well-known buildings at home and abroad have begun to use titanium metal. The advantages of titanium metal as a building decoration material one is corrosion resistance. Titanium metal in the natural environment, is not a corrosion resistance phenomenon, especially in the coastal and Marine environment. Titanium metal ten thousand years is not rotten, especially suitable for replacing ordinary steel and stainless steel building exterior walls, gates, guardrail and so on. The second is light weight, the third is not easy to scale. These have advantages over different materials. However, the titanium materials used for external walls of domestic buildings are mostly imported from foreign countries (Japan), because the domestic titanium plates appear colorful in the sun. Baoji Titanium Industry Research Institute uses vacuum titanium plating to alter the appearance color of titanium materials to solve this problem. Independently developed by Baoji Titanium Industry Research Institute, titanium bamboo section architectural ornaments have installed more than 60,000 square meters of building exterior walls in Fujian Min-Taiwan Cultural Square. It has become the first choice of international design masters to design buildings with titanium metal. It is also hoped that additional independently developed building decorations can be put into use in China in the future.
In daily life, titanium metal has non-corrosion, light weight, great strength, bacteriostatic, easy to wash and other excellent characteristics, made of titanium tableware, kitchenware, ornaments, sports equipment, etc., can be seen everywhere in our lives.
Metals have been a part of our lives since the Bronze Age, but did you ever think that numerous of the metals and materials around you could have an adverse effect on your health?
First of all, let's take a look at our most commonly used stainless steel products. Stainless steel is made of iron chromium alloy into nickel, molybdenum, cadmium, manganese and other trace metal elements. These trace metal elements are harmful to the human body. Long time use will cause cancer! In addition, some bad businesses use garbage iron to manufacture. Its harm to people will be greater. Following iron, iron is easy to rust, the human body absorbs too much iron oxide, namely rust, will be harmful to the liver! With iron pot to the dish of iron, is trivalent iron, the human body is not able to absorb, the human body can only absorb bivalent iron. And then there's aluminum, which can cause aluminum poisoning and is unsafe for long-term use. In life, the most common non-stick pan, is the use of "Teflon" paint, can not be used at elevated temperature, if the non-stick pan sticky phenomenon is because "Teflon" paint off by you eat into the stomach. And clay POTS, casseroles, numerous are added with heavy metal dyes, rather than natural. Finally, there is glass, numerous of which are added with heavy metals such as lead, hence the name "lead-free glass". Thus, titanium metal is the safest, harmless metal to the human body, therefore the price of pure titanium products is not overly low.
Titanium jewelry has non-toxic sterilization, never corrosion, never changes color, no allergies and other characteristics, and now a large number of frames are using titanium manufacturing, titanium memory alloy frames also have memory, how to bend can be restored to the original shape.
The development of titanium metal has just started and is still on the rise. Many people do not understand it. I hope this article can arouse everyone's interest in understanding titanium, so that titanium can penetrate into all aspects of your life and bring benefits to your life, but also promote the development of the titanium industry and make China's titanium industry bigger and stronger!
