Zirconia ceramic grinding and cooling method

Zirconia ceramic grinding method Zirconia ceramics have high structural strength at high temperature and have a negative temperature coefficient of resistance. Therefore, under certain circumstances, the material of the product needs to be ground to a certain extent. The specific methods are as follows:

• (1) Mechanical grinding of zirconia ceramics: When constructing zirconia ceramics on a large area, in order to improve work efficiency, mechanical grinding methods, such as electric grinders (disc type, vibration type), can be used.
• (2) Dry grinding of zirconia ceramics: use sandpaper for grinding. It is suitable for grinding hard and brittle paints. The disadvantage of grinding zirconia ceramic materials is that a lot of dust will be generated during the operation, which will affect environmental hygiene.
• (3) Wet sanding of zirconia ceramics: sanding with sandpaper dipped in water or soapy water. Water grinding can reduce wear marks, improve the smoothness of the coating, and save sandpaper and labor. However, after water grinding, you should pay attention to spraying the lower layer of paint. First, you must wait for the water-grinding layer to completely dry before applying the lower layer of paint, otherwise the paint layer will easily whiten. In addition, the substrate with strong water absorption should not be water milled.

Cooling and Setting of Zirconia Ceramic Structural Parts

• (1) Zirconia ceramic vacuum cooling and shaping: the method of vacuumizing the outside of the tube to make the outer surface of the tube adsorb on the inner wall of the shaping sleeve to cool and determine the outer diameter. The method is especially suitable for extrusion of ultra-high molecular weight polyethylene ceramic needle gauge structural parts.
• (2) Cooling and shaping by internal pressure method of zirconia ceramics: it is a method of using pressurized compressed air in the zirconia ceramic structure, and adding a cooling and shaping sleeve to the tube, so that the outer surface of the tube is attached to the shaping sleeve and rapidly cooled and hardened to determine the outer size. , the pipe is evenly drawn out by the traction device.
• (3) Cooling and shaping of the zirconia ceramic sizing port (ejection method): This method directly ejects the zirconia ceramic structural parts without a traction device. The head structure of the ejection method is characterized by: the core die is straight The part is about 10-50mm longer than the die. The screw thrust pushes the pipe out of the machine head and directly into the cooling water tank. The outer surface of the pipe is cooled and hardened, and the inner surface is sleeved on the mandrel and cannot shrink inward to form a shape.
