Advantages And Disadvantages Of SMD Ceramics And Welded Ceramic Liners

The two commonly used methods for installing ceramic linings in wear-resistant ceramic pipes are direct paste type and stud welding type, both of which can improve the service life of the pipe and protect the inner wall of the pipe steel from the impact wear and corrosion of the material. , but the two are different in cost, process, and use effect. Let's take a look at the advantages and disadvantages of pasted ceramic linings and welded ceramic linings in wear-resistant ceramic pipes.

The advantages of the paste-type wear-resistant ceramic lining are that the construction cost is relatively low, the process is relatively simple, and it can be installed in small pipes with a diameter of about 80mm. Even equipment with a slightly more complex internal structure can also install paste-type wear-resistant ceramics; The disadvantage of the paste-type wear-resistant ceramic lining is that the connection between the ceramic and the equipment mainly depends on the ceramic adhesive. The temperature exceeds 200°C, and the ceramic may fall off when the material is impacted. Therefore, the process of directly pasting the ceramic sheet is not suitable for application at high temperatures. and impacted areas.

The advantage of the welded wear-resistant ceramic lining is that it is fixed by a combination of stud welding studs and inorganic adhesives, which can run at a high temperature of 600 ° C for a long time. Because the fixing is more firm, it can be used in high-speed machines and other moving parts. The wear resistance and impact resistance are better when used in equipment or parts that are subjected to greater impact; the disadvantage of welded wear-resistant ceramic linings is that the construction cost is relatively high, the process is more complicated, the labor cost is higher, and welding is required. equipment, cannot be used in small pipes.

The adhesive type wear-resistant ceramic and the welding type wear-resistant ceramic lining have their advantages and disadvantages, which need to be selected according to the actual situation, but the wear-resistant ceramic adhesive used needs to be carefully selected, because the ceramic is difficult to combine with other materials, if the ceramic is bonded If the agent is not selected properly, the ceramic may fall off because the connection is not tight, resulting in bad influence.
