Tortoiseshell net wear-resistant castables and tortoise shell net ceramic wear-resistant materials are actually amorphous refractory materials combined with tortoiseshell nets for wear-resistant construction of industrial equipment. Tortoiseshell net ceramic wear-resistant material is a kind of wear-resistant coating commonly used in industry. The coating has the advantages of high hardness and wear resistance. It can improve the efficiency of enterprises, prolong the service life of equipment, and reduce the operating costs of enterprises, so it is very popular in the industry.
Tortoiseshell Net Castable, Flue Anti-Abrasive Material
Tortoiseshell net castable, tortoiseshell net wear-resistant clay. It is mainly composed of wear-resistant aggregates such as brown corundum and silicon carbide and fine powder. At the same time, add sintering agents, ultrafine powder, coating additives, ceramic powder, composite material powder, composite adhesive, etc. The particles are closely packed, forming quickly and having high strength. It can reach the design strength in three days, so there are no major defects in use. The bulk density is high, and its strength at room temperature can reach more than 200Mpa.
Application of ceramic wear-resistant castables. Ceramic wear-resistant castables are mainly suitable for pipes and flues with high dust concentrations and serious acid and alkali erosion and wear in cement plants, power plants, metallurgy, and other industries. Dust collector, vertical mill equipment, feeding hopper, feeding chute, powder classifier, and other equipment and conveying pipelines. This product has been applied in more than 400 cement plants, power plants, and mining enterprises. In the cement industry, this product has been supplied to Loesche vertical mill, vertical mill, Ube vertical mill, raw material mill, clinker mill, coal mill outlet air duct, grate cooler to electric dust collector duct. And the conveying pipelines such as the upper shell of the powder classifier. It is a new generation of wear-resistant materials that replace traditional ceramic sheets, wear-resistant steel plates, and cast stone plates.
The Characteristics of Wear-Resistant High-Strength Tortoiseshell Mesh Wear-Resistant Castables
Wear-resistant ceramic coating is a new type of artificial material, which is a non-metallic cementitious material. It is a powdered ceramic coating produced by using acid and alkali-resistant artificial synthetic raw materials through strict process ratio and advanced synthesis technology. It can be used to form a coating on the surface of other metals or non-metals to improve its performance.
The performance of wear-resistant mortar has high mechanical strength and rigidity, which is difficult for ordinary reinforced concrete to achieve. The main reason is that the combination of the internal atoms is mainly by the combination of ionic bonds, and the force between the ions is relatively large, so the macroscopic performance is high strength and rigidity. At the same time, the wear-resistant mortar also has good toughness and shock resistance, which ensures the stability of its work, and the temperature has little influence on it. But what is also important is that the environmental compatibility of wear-resistant cement is very good, because its main component is silicate, which does not pollute the environment and does not produce harmful substances such as metal ions. It is a new material.
Wear-resistant cement refers to the general term for ceramic coatings with high-temperature resistance for various purposes. There are many kinds of wear-resistant mortar and a wide range of uses, which are all derived from its performance characteristics.
High-temperature resistance. Ceramic anti-corrosion coatings have high-temperature resistance, and composite ceramic high-temperature anti-corrosion coatings can withstand temperatures up to 1200°C. The temperature resistance of general anti-corrosion coatings is only about 400 ℃.
High hardness. The coating can form a dense ceramic structure after high temperatures, and the hardness can reach 5-6H. Wear-resistant and impact-resistant, twice as hard as traditional anti-corrosion coatings.
Wide range of acid and alkali resistance. It can withstand the corrosion of weak acids and alkali and can withstand the corrosion of alkalis. It is waterproof and moisture-proof, and can also prevent the corrosion of acid and alkali gases. The range of PH resistance is wide, and the application range is wider than traditional anti-corrosion coatings. Strong corrosion resistance and long service life.
Application Advantages of High-Strength Tortoiseshell Mesh Wear-Resistant Castables
Wear-resistant clay belongs to the field of functional coatings and is a new type of water-based inorganic coatings. It is mainly composed of nano-inorganic compounds and water as a dispersant. After coating, it is usually cured by low-temperature heating to form an insulating coating film with properties similar to ceramics. After years of joint research and experiments, the company has successfully developed high-temperature-resistant ceramic insulating coatings, whose performance has surpassed that of insulating coatings. High-temperature and wear-resistant cement have excellent properties such as insulation, temperature resistance, wear resistance, high hardness and thermal shock resistance, and medium thermal expansion coefficient.
High temperature-resistant and wear-resistant cement, using the high-temperature solution, the long-term temperature resistance can reach 1800 ℃. Water-based inorganic ceramic materials, the coating is made of pure inorganic polymer high-temperature solution, and the pigment is made of high-resistance inorganic crystal materials. Insulating coatings can work at 1700°C for a long time. The volume resistivity is greater than 1016Ωm, and the dielectric strength (breakdown strength) is greater than 104KV/m. Good chemical stability, aging resistance, and corrosion resistance. No flash point, ignition point, high hardness, hardness greater than 7H.
High temperature resistant ceramic insulating coating, temperature resistant to 1700°C. A layer with high volume resistivity can be formed on the surface of the coated object, which can withstand a strong electric field without being broken down. The coating has high mechanical strength and good chemical stability and is resistant to aging, water, and chemical corrosion. It is also resistant to mechanical and thermal shocks. The insulating coating can work continuously at the corresponding working temperature. The high-temperature-resistant ceramic insulating coating is a water-based inorganic high-temperature coating. It adopts a proprietary pure inorganic polymer high-temperature solution and is composed of high-resistance inorganic crystal materials. As α-alumina, silicon nitride, mica flakes, etc. are used as fillers. The coating has high volume resistivity (greater than 1012Ωm) and high dielectric strength (higher than 104KV/mm). It is suitable for painting high-temperature insulation on various fire-resistant cables. The paint is fired to form the insulating layer of the hard ceramic-like shell. The insulating layer of this hard ceramic-like shell can prevent the flame from spreading and protect the normal state of the substrate from damage.
