Graphite has a lot of different high -quality characteristics. It is widely used in the metallurgical industry forging, the setting glass of mezzanine, and the industrialization of semiconductor materials. What are the high -quality characteristics of graphite mold? Let's take a look with graphite products manufacturers.
1. High -quality heat transfer and conductivity. The conductivity of graphite molds is 100 times higher than that of ordinary mining companies. The heat transfer is beyond metal composite materials such as steel, iron, and lead. The heat transfer coefficient decreases with the temperature, and even at a very high temperature, the graphite becomes anrmal insulation.
2. Very good thermal resistance. The solution point of graphite is 385050 ° C, and the melting point is 4250 ° C. Even if it is burned by high temperature, high voltage and electricity, the net damage is not large, and the line expansion coefficient is not large.
3. Excellent thermal shock -resistant characteristics. Graphite molds should bear the strong change of temperature when applying at room temperature without destroying. When the temperature gene mutations are mutated, the volume of the graphite is not large, which is not easy to cause cracks.
4. Very good organic chemical reliability performance. Graphite has excellent organic chemical reliability in normal temperature. It is not easy to reflect with most metal materials, which can be etching the acidity, alkali resistance and organic solution.
5. Excellent anti -heating destruction. At high temperature (above the temperature of most copper -based embryo bodies), the pressure resistance of the pressure is expanded as the temperature increases. At 2000 ° C, the graphite mold shells are doubled.
6. Have excellent moisturizing and wear resistance. The wetness performance of graphite shells lies in the size of graphite scales. The larger the fish scales, the smaller the friction resistance, and the higher the moisture performance.
7, high -quality ductility. Graphite has good ductility and can become very thin years.
8. Excellent processing characteristics. It is convenient for processing, has good processing characteristics of machinery and equipment, and can be made into a complicated and high -precision graphite shell.
