Wear-resistant ceramics, also known as modern ceramics, mainly comprise high-purity alumina. Because their toughness and hardness are much higher than ordinary daily-use ceramics, they can be used as wear-resistant materials in industrial equipment.   As an industrial wear-resistant material, wear-resistant ceramics have good wear and corrosion resistance. Still, because of their relatively high hardness, which is close to the hardness of diamonds, it isn't easy to reprocess wear-resistant ceramics. Let's get to know the processing technology of wear-resistant ceramics.    The processing technology of wear-resistant ceramics has the following three categories according to the processing method: 1. Surface treatment: Use diamond grinding discs to grind wear-resistant ceramics or use sandpaper to polish the surface of wear-resistant ceramics; 2. Cutting treatment: Because the hardness of wear-resistant ceramics is relatively high, ordinary cutting machines cannot cut ceramics, and special equipment such as diamond cutting discs or ultrasonic waves, lasers, and water jets are required for cutting treatment; 3. Surface marking: using photolithography technology or etching technology through chemical or physical means to make wear-resistant ceramics form concave-convex or hollow-out molding effects; 4. Wear-resistant ceramics are difficult-to-process materials, which cannot be processed in general machining workshops. The processing of wear-resistant ceramics generally requires special processing tools and processing techniques, so it is a better choice for professionals to operate and process.    

The scientific name of zirconia is zirconia, and its molecular formula is ZrO2. It is the main oxide of zirconium. The minerals containing zirconium in nature mainly include baddeleyite and zircon. Zirconia is usually a white odorless and tasteless crystal, insoluble in water, hydrochloric acid, and dilute sulfuric acid, chemically stable, and has the characteristics of high hardness, high melting point, high resistivity, high refractive index, and low thermal expansion coefficient. Wear-resistant ceramics, refractory materials, machinery, electronics, optics, aerospace, biology, chemistry, etc. have been widely used in various fields. Our common artificial drills and dental implants also use zirconia as the main material.    Properties of Zirconia 1. High hardness: The hardness of zirconia products can usually reach more than 7.5 on the Mohs scale, and the hardness of some products such as zirconia ceramics can exceed 9, second only to diamond. High hardness means that it has strong wear resistance, so zirconia ceramics are good wear-resistant materials. 2. High melting point: The melting point of zirconia is as high as 2715°C, and its chemical properties are stable. It is an excellent refractory material. 3. Low thermal conductivity and low expansion coefficient: The thermal conductivity of zirconia is relatively low among common materials (1.6-2.03W/(m.k)), and the thermal expansion coefficient is close to that of metal. Therefore, zirconia ceramics are suitable for official ceramic materials, such as zirconia ceramic mobile phone exterior structural parts. 4. Special conductivity: Zirconia does not conduct electricity at room temperature, and its resistivity is extremely high. However, in a high-temperature environment, zirconia has a certain conductivity. Using this principle, zirconia is also used in many electronic devices.  

Construction process 1. Grind and dust and degrease the metal surface where ceramics need to be pasted (if there is an oil stain, it should be cleaned with 99% acetone; if the bonding surface is non-metallic, the surface should be polished and roughened). 2. Stir the glue evenly, mix, and mix thoroughly according to A: B=2:1 (weight ratio), apply it on the metal surface, then paste the wear-resistant sheet, hit it with a rubber hammer, and cure it at room temperature for 2 hours. 3. After curing at room temperature for 8 hours, use a small hammer to gently tap to check, and listen to the sound to judge whether there is any phenomenon that the adhesive is not fully coated. If so, it needs to be partially re-pasted.    Precautions 1. When the humidity is high in the rainy season, in order to prevent rust, glue should be applied immediately after grinding to prevent rust. 2. The proportion of glue should be accurate to avoid construction quality problems caused by inaccurate glue mix. 3. When the temperature is lower than 10°C, heating and curing should be adopted, and an iodine-tungsten lamp can heat the surface to be bonded to about 30°C, apply glue and glue bond, and heat until cured. If heating measures are not taken, especially when the temperature is lower than 0°C, the adhesive will freeze and the surface looks cured, but there is no bonding strength. The user will experience ceramic peeling off during use. The heating temperature should not exceed 50°C, otherwise, it will cause the glue to react violently and cause foaming, affecting the bonding strength.

Today we will talk about the application of abrasion-resistant ceramic lining in the wear-resistant feeding chute of the powder concentrator. First of all, what is the powder concentrator? The powder concentrator is an important component of the closed-circuit circulating grinding system. It is widely used in the production systems of cement plants and other powder concentrators and plays the role of regulating the size of finished products. Its reliability affects the normal operation of the entire production line. Due to the high abrasiveness and humidity of slag, the cleaning and replacement of worn parts of the powder concentrator have seriously affected the normal production of the powder concentrator.    Abrasion-resistant ceramic lining can solve this problem well as a solution for wear-resisting and anti-blocking of the feeding chute of the powder concentrator. The alumina ceramic lining is made of microcrystalline wear-resistant aluminum oxide, sintered at 1700 ° C and high temperature. It has high hardness and wear-resistant properties and can be widely used in powder concentrators of grinding systems in thermal power, cement, chemical industry, metallurgy, port, mining, and other industries.   The ceramic lining brick is fixed by pasting, which facilitates installation and replacement, reduces the specification and quantity of spare parts, and saves user costs. Secondly, the alumina lining has wear resistance, a smooth surface, no scraping, and no material, which can effectively prevent material blocking and is convenient for cleaning.   High alumina ceramic lining bricks have been applied in many industries because their characteristics can be targeted at different types of materials. Its wear-resistant and anti-clogging effect is noticeable, which greatly reduces the probability of material clogging, prolongs the equipment cleaning cycle, reduces the user's downtime and maintenance time, and creates additional economic benefits for the user, and the response is quite good.  

Alumina precision ceramics is a high-tech ceramic product made of alumina materials. Different from ordinary alumina ceramics, alumina precision ceramics are mainly reflected in "precision", which is specifically reflected in the more complex structure of the finished product after production. In terms of relatively small size and less secondary processing, the performance characteristics of alumina precision ceramics are similar to those of alumina ceramics, such as high-temperature resistance, wear resistance, corrosion resistance, and high hardness. Therefore, alumina precision ceramics are widely used in electronics, information, and communications. , aerospace, military, and other fields have also been widely used.   Due to its good physical and chemical properties, alumina fine ceramics occupy a significant position in many fields. First of all, in the electronic field, alumina precision ceramics are mainly used in the production of capacitors, electronic potentiometers, voltage regulators, and other electrical components. Because of its high-temperature resistance, vibration resistance, corrosion resistance, and mechanical strength, it can ensure the efficient and stable operation of electrical components.   In the industrial sector, fine alumina ceramics also occupy an important position. It has very high hardness and wear resistance. It can be made into wear-resistant parts such as wear-resistant pipes, used in industrial machinery, and used in the production of mechanical precision parts. In medical equipment and other fields, alumina precision ceramics can be used to make human body substitutes such as artificial arms and artificial knees and they have good biocompatibility and mechanical properties.   To sum up, alumina precision ceramics have good performance and wide application, and its manufacturing process is relatively strict, but it has high added value and economic benefits. Therefore, the future market prospect of alumina fine ceramics is very broad and has great development potential. http://www.ybnceramic.com/wear-resistant-ceramic-pipe/alumina-toughened-zirconia.html

The wear-resistant ceramic lining board solves the wear problem for heavy wear industries such as cement, steel, mining, lithium battery, and metallurgy. The main material of the wear-resistant ceramic lining board is alumina, and its fracture toughness KΙC≥4.8MPa•m1/2, bending strength ≥290MPa, compared with metal materials such as steel, the impact resistance is not very strong, but through some special processes, the impact resistance of wear-resistant ceramic linings can be greatly improved, so what is the impact resistance of wear-resistant ceramics? Woolen cloth? How to improve the impact resistance of wear-resistant ceramic liners?    Surface design with spherical protrusions The unique mechanical properties of spherical protrusions can evenly disperse the impact force on the liner, reducing the possibility of the liner being broken by the impact. It is a relatively common method to improve the impact resistance of wear-resistant ceramic liners.   Increase the rubber area on the surface of the liner The wear-resistant ceramic liner is mainly used in combination with rubber. We can make full use of the characteristics of the weak impact resistance of ceramics and the strong impact resistance of rubber, and give full play to the advantages of both. Ceramics are used for wear resistance and rubber for impact resistance. During the process, some rubber is exposed on the surface of the liner (round ceramic sheets can be used). It should be noted that as the rubber area on the surface of the liner increases, the ceramic area will decrease accordingly. While the impact resistance is improved, the wear resistance will be reduced. When using it, it needs to be considered comprehensively according to the actual working conditions.   Alumina for toughening treatment The impact resistance of alumina wear-resistant ceramics is indeed weak, but this problem can be solved by spherical design, vulcanized rubber, and adding zirconia, so that wear-resistant ceramic linings can adapt to most heavy wear and strong impact conditions.

The wear-resistant elbow is a pipeline connection part commonly used in industrial engineering. It is widely used in thermal power, metallurgy, steel and cement, and other fields. Common materials for wear-resistant elbows Special high-temperature glue is often used to paste wear-resistant ceramic sheets inside the steel pipe elbow when producing wear-resistant elbows. Therefore, we also call the elbow a ceramic-lined pipe, also known as a wear-resistant ceramic elbow. With the development of science and technology, the materials for making wear-resistant elbows are also constantly improving. Common materials include cast stone, cast steel, alloy, and centrifugal-casting composite ceramics.      Production of wear-resistant backpack elbow In some environments where the on-site working conditions are very harsh, in order to protect the elbow from wear and tear due to material wear, on the basis of the existing wear-resistant elbow, a wear-resistant backpack is added to the arc of the back. The wear-resistant elbow of the backpack is a wear-resistant elbow backpack made of steel pipe, which is filled with uniform wear-resistant materials so that the filler is not easy to fall off. In addition, wear-resistant ceramic materials need to be installed inside the wear-resistant elbow as a lining, which can achieve a double-layer wear-resistant effect, thereby further prolonging the service life of the wear-resistant elbow. Application of wear-resistant elbow The wear-resistant elbow made of high-hardness material has the characteristics of high wear resistance, which can maintain high transmission efficiency and wear resistance at high temperatures. Wear resistance mainly depends on materials and working conditions. Common wear-resistant materials include forged wear-resistant steel, martensitic manganese steel, moderately heat-treated low-alloy steel, and graphite steel. Wear-resistant elbows are widely used in wear-resistant pipes in power plants, steel mills, and coal preparation plants. The wear-resistant elbow is an important component in engineering, which is used to solve the problem that the elbow is easily damaged. Wear-resistant elbows are made of various materials and have the characteristics of high wear resistance. When selecting a wear-resistant elbow manufacturer, you can judge by understanding its technical standards and production strength. I hope the above information can be helpful to everyone.

The elbows of the pulverized coal transportation pipelines of thermal power plants are particularly worn and have long been the key parts of power plant maintenance. The service life of the pipelines is directly related to the operating costs and economic benefits of the entire power plant. From the wear resistance, high temperature resistance and corrosion resistance of the pipeline Considering the convenience of function and construction, the application of wear-resistant ceramics in pipes can fundamentally solve this problem.   The wear-resistant ceramic sheet uses AL2O3 as the main raw material and is a special corundum ceramic produced by calcining at a high temperature of 1700 Baidu. Its Rockwell hardness is HRA80-90, the hardness is second only to diamond, which can greatly extend the service life of the elbow of the pulverized coal pipe.   The wear-resistant ceramic commonly used in the wear-resistant elbow of the pulverized coal pipeline adopts the welding process with a hole in the middle, and is equipped with a steel bowl and a porcelain cap. The construction of this wear-resistant ceramic sheet is also more convenient. The ceramic sheet is directly welded to the steel body, and the overall appearance is all ceramic surfaces. This further strengthens the firmness of the ceramic sheet pasted on the pulverized coal pipe. The advantage of this type of ceramic patch is that it is easy to repair and maintain. Even if the pipeline is worn during operation, it can be directly repaired, saving manpower and material resources.   Wear-resistant ceramic sheets are used in various industrial wear environments, such as wear-resistant and anti-corrosion of fan impellers and casings. Wear-resistant ceramic sheets are also often used to compound wear-resistant pipe elbows with various metal materials. The wear-resistant ceramic sheet can also be used in the wear-resistant and wear-resistant of various types of water pumps, slurry pumps, circulating water pumps, impellers and various overcurrent components.
