General knowledge of coating: properties and application of rutile

Core tip: rutile is a pure titanium dioxide, titanium dioxide content in general is more than 95% The reserves of natural rutile are much less than that of ilmenite, accounting for 2.5% of the total ilmenite Rutile, as an important non-metallic mineral, has a wide range of uses Its main deep processing directions are as follows: (1) Rutile is an important raw material for refining titanium and titanium alloy Titanium and titanium alloy have the characteristics of high temperature, low temperature, corrosion resistance, high strength and small proportion, which are widely used in military aviation, aerospace, navigation, machinery, chemical industry, desalination, etc (2) Jin Hongshi Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings news: rutile is a relatively pure titanium dioxide, titanium dioxide content in general is more than 95% The reserves of natural rutile are much less than that of ilmenite, accounting for 2.5% of the total ilmenite As an important non-metallic ore, rutile has a wide range of uses Its main deep processing directions are as follows: (1) rutile is an important raw material for refining titanium and titanium alloy Titanium and titanium alloy have the characteristics of high temperature, low temperature, corrosion resistance, high strength and small proportion, which are widely used in military aviation, aerospace, navigation, machinery, chemical industry, desalination, etc (2) Rutile is also the best raw material for producing rutile titanium dioxide Titanium dioxide is used in coating, papermaking, plastics, ink, chemical industry and other industrial sectors (3) Rutile itself is one of the necessary raw materials for high-grade welding electrodes It is widely used as slag making agent for welding electrodes, flux cored wires, fluxes and other welding materials, which can stabilize the arc and regulate the physical properties of the slag With the rapid development of science and technology, it has been found that rutile titanium dioxide has higher covering power, anti loss of light and anti pulverization than anatase titanium dioxide, and the research on rutile titanium dioxide has aroused an upsurge At present, the main methods of titanium dioxide production at home and abroad are sulfuric acid method and chlorination method Sulfuric acid method is the most mature technology for titanium dioxide preparation, which is also the most widely used method at home and abroad However, the titanium dioxide products prepared by sulfuric acid method are mostly general-purpose, which is difficult to meet the market demand of high-end products The chlorination process uses titanium containing raw materials to react with chlorine gas to produce titanium tetrachloride, such as chlorinated high titanium slag or artificial rutile or natural rutile, etc after rectification and purification, gas-phase oxidation, gas-solid separation, dechlorination and other processes, the finished product can be obtained Compared with sulfuric acid method, chlorination method is more difficult to produce titanium dioxide, with special raw materials and high cost However, chlorination method is a continuous process with simple process, less process control points and easy to achieve optimal product quality control Titanium dioxide has a wide range of uses in modern industry, especially in recent years, with the increasing demand for high-end titanium dioxide, rutile is also rising Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
