  Ceramic Grinding Abrasive is materials with relatively stable chemical properties. They are high in hardness, easy to use, and energy-saving and environmentally friendly. They are mainly used as abrasives. In the production process, due to some operational problems, the layering will cause the abrasives to become brittle. Influencing the use, let's analyzes the cause of the layering.

  1. When the Ceramic Grinding Abrasive is processed, the mold sleeve becomes large when subjected to high pressure, and shrinks when not pressurized, so that the intermediate layer is cracked and bulged up and down;

  2. The gas in the abrasive does not run out, the two sides have been compacted and concentrated on the middle to form an air layer. After the external pressure is removed, the gas expands on an intermediate layer;

  3. The water moves downward from the pressure side, and the double-side pressure causes the middle and lower parts to concentrate and the strength is reduced. Therefore, the layered waste is also caused. Even if there is no crack after molding, cracks may occur to fir, so when drying, It is more reasonable to be able to dry the plate;

  4. When the pressure is high, the blank has a high elastic expansion and contraction. The finer the particle size of the Ceramic Grinding Abrasive is, the closer the contact between the particles is, and the smaller the stress transmission changed are. Also, the abrasive are pressed on both sides in the pressing, the middle layer of the product is weakly combined, the friction is upper and lower, and the elasticity is different, so that the layer crack is generated under the action of elastic stress.

  This article gives you a detailed explanation of the causes of the Ceramic Grinding Abrasive layer. We can see that the main cause of this problem are because the pressure is not applied properly, so pay attention to the pressure control during operation. Maintain a reasonable range to prevent damage to abrasive particles of handling.
