high temperature industrial 99% Alumina Ceramic Plate
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
The Alumina Ceramic firstly treats the outer diameter of the granulation screw first, and the surface is sprayed with tungsten carbide alloy, and then the granulation screw is smoothed and matched with the inner hole of the cylinder, and the bottom diameter of the granulation screw is treated by electroplating hard chrome. In response to the demand for various plastic products, most of the ultra-engineering plastics currently used contain additives such as fire retardant, glass fiber, stone powder, modifier, etc., resulting in rapid corrosion, wear and shortening of life of the barrel and screw. Now due to the increase of glass fiber in various engineering materials, as well as various fillers, the addition of modifiers. The production of plastics such as bakelite and iron powder is extremely easy to wear the material pipe and screw. After years of research and development, our company has successfully developed a new technology for repairing old screws and material tubes. After years of exploration and practice, the technology is basically mature. Whether it is the material tube, the screw concentricity, the gap, or the inner hole of the material tube, the smoothness of the outer diameter of the screw is almost the same as that of the new material tube and the screw. Professional refurbishment, so that the old screw and barrel of each enterprise turn waste into treasure to create benefits and business opportunities for customers is the purpose of honest people! Processing technology: the inner hole of the material tube is honed and polished, and then polished. The outer diameter of the screw is smoothed and roughened, and the carbonized alloy is sprayed on the surface, and then the outer diameter is further polished to match the inner hole of the material tube, and the rear screw is plated with hard chromium.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
