Wear-resistant ceramic coating high-strength wear-resistant refractory Gongyi Ming Xin

 巩义明 Xin wear-resistant ceramic coating materials Description: wear-resistant ceramic coating is a non-metallic gelling material, it is the use of synthetic materials acid and alkali ratio through strict process and advanced technology into an inorganic polymeric Species powdered ceramic material. At the construction site, the addition of such a special liquid inorganic adhesive material, the use of artificial or mechanical means applied in the liner or surface equipment, through a series of chemical reactions at room temperature the formation of high strength and hardness, to combine the strength of ceramics standard, therefore called wear-resistant ceramic coating. It has a convenient construction, easy maintenance and low cost characteristics have been widely used. Wear-resistant ceramic coating is mainly composed of aggregates and ultrafine powder combined two-phase composition, particle closely packed, bulk density, their strength at room temperature up to about 150MPa. General concrete and refractory castable can not match. The main raw materials is the use of ionic compounds and some synthetic covalent compounds, ionic bonding firm, and combined with the system due to the use of composite reinforced measures and special treatment to form a chemical combination of strength and stiffness so great that it can effectively resist the impact of the material and shear stress. Wear-resistant ceramic coating characteristics: 1) has a very high mechanical strength and rigidity, wear-resistant ceramic coating consists of wear-resistant aggregate and binding system components, the density is very large and there was no macroscopic defects, strength of up to 150Mpa, general concrete and refractory castable can not match, mainly using the ionic compounds and some synthetic covalent compounds, ionic bonding firm, so great strength and stiffness, which can effectively resist the impact and shear stress of the material. The combined system due to be taken to strengthen the measures and special treatment complexes to form chemical bonding, resulting in high strength. 2) has excellent toughness and shock resistance, abrasion resistance of the ceramic material using non-directional and directional rigid fiber mesh reinforced measures to further improve the toughness by coupling, so strong fracture toughness, can effectively prevent the damage caused by the impact and peeling. Other hand, because of its ionic and covalent bonds as strong, relatively high bond energy, it has little effect on low temperature, and its high frequency vibration, it is difficult to pose a threat to the normal temperature, no thermal shock damage. 3) overall good, because the wear-resistant ceramic coating double reinforcement measures taken, and some even take a variety of reinforcing measures to effectively improve the material properties. And ceramic materials such as low coefficient of expansion, and its volume stability, it is impossible to crack, which is good overall, in addition to the construction of an overall construction, no seams appear, thus further improving overall. 4) Environmental compatibility, the use of synthetic materials acid- and alkali-resistant, and will not react and slag, and because of this raw material, mostly high-temperature synthesis, crystal growth is good, structural integrity, the ambient temperature does not It caused a big impact, an environmental inert materials, thus poor sensitivity to the environment. 5) no environmental pollution, wear-resistant ceramic coating is an inorganic non-metallic materials, the main ingredients of the silicate, and the Earth's lithosphere similar ingredients, will not cause soil degradation and pollution of heavy metal ions, will not affect the environment, is a green environment-friendly products. Because of these characteristics, normal wear-resistant ceramic coating wear resistance is nine times 16Mn steel 65Mn steel 8 times, 45 times the refractory castable can suitable for cement, defense, oil, chemical industry and other high, corrosion resistant layer of low key processing equipment, is to replace the existing wear-resistant ceramic, wear-resistant steel an ideal material for the next generation to solve the various sectors due to winnowing abrasion, impact abrasion, member frequent downtime and other issues.
