Method of inspecting porcelain surface of glass lined reactor

The inner surface of the glass lined reactor is a layer of silica glass, which has good corrosion resistance to most chemical raw materials. Through the above description, everyone must also understand the important influence of the enamel layer on the performance of the reactor. Therefore, the inspection of the enamel layer is also important. The quality inspection method of the enamel layer is as follows:

　　a. At a distance of 250mm from the surface of the enamel layer, use a 36V, 60W hand lamp to visually inspect the surface of the enamel layer. There should be no following defects:

　　 1. Cracks, scales, and local peeling;

　　 2. Dark bubbles, powder tumors;

　　 3. Obvious scratches;

　　4. Local deformation that hinders the use of equipment caused by the firing bracket;

　　 5. Affect the hairline used in the glass lined reactor.

　　b. The number of foreign particles on the enamel layer per square meter should not exceed 3, and the area of each spot should not be less than 4mm.

　　c. Color difference is allowed on the surface of the enamel layer, but it should be ensured that the performance of the color difference part does not affect the use of the equipment.

　　d. The thickness of the enamel layer is 0.8-2.0mm, and the thickness of the enamel layer of the mechanical seal section of the enamel stirrer can be allowed to be reduced to 0.6mm. The thickness of the enamel layer should be huge, and the thickness area should be smoothly transitioned.

　　 The enamel layer quality inspection methods and standards of the glass lined reactor, we have a more detailed introduction in the above content. During the acceptance process of this type of product, you can check according to the above methods to ensure that the selected product can have sufficient service life.
