What is a dovetail wear-resistant ceramic lining?

图片
Chemshun Dovetail wear-resistant ceramic lining is a wear-resistant lining fixed to the surface of the equipment through a dovetail structure. It is mainly used to prevent internal wear of the equipment. Its design achieves firm mechanical fixation through the clamping of the dovetail guide rail and the ceramic lining 1) Structural features Dovetail design: stable installation through clamping, fits the surface contour of the equipment, reduces stress concentration, and adapts to complex working conditions such as high temperature vibration Ceramic material: mainly alumina ceramic, high hardness (HRA ≥ 82), strong wear resistance, high temperature resistance (about 750 ° C), corrosion resistance 2) Advantages High wear resistance: Made of high-purity aluminum oxide silicon nitride and other raw materials, it has high hardness and strong wear resistance Corrosion resistance: It can resist the erosion of chemical substances such as acids, alkalis and salts, and is suitable for corrosive ...

How to reduce the production cost of alumina wear-resistant ceramics?

图片
The production cost of alumina wear-resistant ceramics is high. In order to reduce the production cost, the following aspects can be considered:   I. Raw material selection 1. Select cost-effective raw materials: Under the premise of ensuring product quality, select alumina powder with relatively low price but satisfactory performance, such as industrial alumina or calcined alumina instead of high-purity alumina powder. At the same time, we can explore the use of a mixture of alumina and other ceramic materials to reduce costs through reasonable proportions. 2. Joint procurement of raw materials: Cooperate with multiple companies for joint procurement and use economies of scale to reduce procurement costs. II. Process optimization   1. Optimize the preparation process: Improve production efficiency, reduce energy consumption and waste generation by improving the preparation process. For example, use advanced sintering technology and mold design to shorten sintering time and r...

Reasons for grinding flanges and pipe ends during the installation of wear-resistant ceramic pipes

图片
The main reasons for grinding flanges and pipe ends during the installation of wear-resistant ceramic pipes are as follows: 1. Ensure sealing Flange grinding: Flanges are key components that connect pipes, equipment, valves and other components in the pipeline system, and their sealing performance is crucial. Grinding the flange surface can remove burrs, dirt and oxide layers on its surface, thereby ensuring that the flange surface and gasket can fit tightly to form an effective seal. This helps prevent medium leakage and ensures the safe and stable operation of the pipeline system.   Pipe end grinding: Similarly, grinding the pipe end can remove unevenness and impurities on its end face, ensuring a tight fit between the pipe end and the flange or other pipe connectors. This helps reduce the risk of leakage and improve the overall sealing performance of the pipeline system.   2. Improve connection strength   Flange connection strength: By grinding the flange surface, the...

what’s polyhedral hollow ball

图片
C hemshun Polyhedral hollow ball filler is made of polypropylene (PP). It is mainly used in cooling towers and purification towers to remove oxygen, chlorine, carbon dioxide and other gases. It has a spherical appearance and the main specifications are φ25mm, φ38mm, φ50mm, and φ76mm. When polyhedral hollow balls are used for sewage treatment, they can purify water quality and meet national standards. It mainly plays the role of gas-liquid contact to achieve heat and mass transfer. It increases the area of ​​gas-liquid contact in the tower and is an important component that affects the heat and mass transfer of the tower.   The polyhedral hollow ball is a spherical filler made of plastic. It is composed of two hemispheres, each hemisphere has 12 blades, and the blades are semi-fan-shaped. The upper and lower blades of the two hemispheres are staggered. This structure of filler has the advantages of high gas velocity, low resistance, large specific surface area, and high operating f...

The role of pall rings in packing towers

Due to the openings in the ring wall, the p all ring greatly improves the utilization rate of the inner space and ring surface of the ring, with low air flow resistance and uniform liquid distribution. It has the advantages of large flux, low resistance, high separation efficiency, and large operating flexibility. Under the same pressure reduction, the processing capacity is more than 50% larger than that of the Raschig ring. Compared with the Raschig ring, this packing has the characteristics of large production capacity, large resistance, and large operating flexibility.   Plastic p all rings   packing is particularly suitable for low-temperature (60-150 degrees) extraction, absorption and washing towers in the petroleum, chemical, chlor-alkali, coal gas, environmental protection and other industries, as contact fillers for carbon dioxide degassing towers, ozone contact reaction towers and other reaction towers.   p all rings ceramics can reduce the shrinkage, dimension...

Chemshun Production process of wear-resistant ceramic tubes

图片
Wear Resistant ceramic tubes is widely used for bulk material handling system , like coal or slurry material conveying , pneumati transport etc. Chemshun ceramics company share how to alumina ceramic tubes produced . 1. Powder calcination: Calcine the alumina ore powder according to different formulas to obtain calcined α -alumina powder suitable for production; 2. Powder grinding: Grind the calcined α-alumina powder according to the formula to prepare for the ceramic powder suitable for molding. Generally, wet ball milling is used; 3. Powder preparation: High-quality powder suitable for green body molding is obtained by spray granulation; 4. Molding: According to the requirements of product design, the high-quality powder after spray granulation is pressed by dry pressing or isostatic pressing to obtain qualified ceramic blocks or ceramic ring green bodies; 5. Sintering: The process of densification of the pressed green body, generally using electric kilns; 6. Installation: After the...

Differences between 92% aluminum content and 95% alumina ceramic sheets

图片
There are differences in performance between chemshun wear resistant ceramic liner tile  with 92% aluminum content and 95% aluminum content, as follows: * Hardness. Wear-resistant ceramic sheets with 95% aluminum content have higher hardness than 92%, which improves their wear resistance to a certain extent. Therefore, the degree of hardness may affect the durability of wear-resistant ceramic sheets. , * Brittleness and degree of dome. In addition, wear-resistant ceramic sheets with 92% aluminum content are relatively tough, while wear-resistant ceramic sheets with 95% aluminum content may be more brittle and may crack during bending or use. This may affect its performance in practical applications. * Price. Wear-resistant ceramic sheets with 95% aluminum content usually have higher production costs due to their higher aluminum content and hardness, which affects their market prices. In general, these two types of chemshun wear-resistant ceramic sheets have their own unique charact...
