The alumina content of corundum raschig ring packing is generally 90%-95%, and the high-aluminum corundum raschig ring reaches more than 90% by increasing the aluminum oxide content. Corundum raschig ring contains a large number of corundum crystals, the strength is much higher than the ordinary raschig ring, and the high temperature resistance is also higher (using more than 1430 ℃ . Generally, the use temperature of ordinary raschig ring is 1000 ° C), which can withstand rapid temperature changes when used above 1200 ° C, and has excellent thermal shock resistance, which is not easy to break and cause blocking bed. Corundum raschig ring packing has high mechanical strength, high temperature resistance, wear resistance, acid and alkali chemical corrosion resistance. It solves the problems that common ceramics are brittle and easy to crack in case of high temperature and temperature change. And because there is a straight round hole in the middle of the raschig ring, it has large and u...

In the field of industrial wear resistance, traditional single-material solutions are no longer sufficient to meet the complex requirements of high wear and strong impact in various working conditions. The rubber-ceramic three-in-one composite plate , as a revolutionary solution, has achieved a breakthrough in material performance through a three-layer composite structure design: the ceramic layer resists wear, the rubber layer absorbs impact, and the steel plate provides support. This composite wear-resistant material is now widely used in heavy industries such as power, mining, and metallurgy, and has become one of the core technologies for extending equipment lifespan and reducing maintenance costs. The rubber-ceramic three-in-one composite plate is composed of wear-resistant ceramics, rubber and metal steel plates. The ceramic layer mainly uses high-purity (92%, 95%) alumina powder as the raw material, which is formed by dry pressing or isostatic pressing. After being sintered at a...

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 reduce energy ...

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 contac...

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...
