Prevention and gray removal of graphite production and processing workshop

The anti -pollution -proof of graphite production and processing workshop is stable in the physical properties of ash graphite and no organic chemical corrosion. Therefore, the removal of the ash in the workshop does not need to consider anti -virus and corrosion resistance, mainly to reduce the concentration value of smoke and dust in the air and collect tiny smoke.First, to ensure the sealing of graphite production and processing workshop, and prevent environmental pollution from smoke and dust. Graphite production and processing workshop air has graphite smoke dust. Graphite smoke should be collected and purified according to the dust removal equipment before removing the workshop.In the secondary, graphite production and processing should be based on the concentration value of the smoke and dust caused by the system. Different CNC lathes, different concentrations of production and processing processes are different. For example, the concentration value of the smoke and dust concen

What are the key features of graphite blocks?

1. Heat transfer and conductivity: Graphite has excellent heat transfer and conductivity. It is compared with general raw materials, and its heat transfer conductivity is moderate. It is 100 times higher than ordinary non -metal materials.2. Organic chemistry reliability: The gas -graphite has excellent organic chemical reliability, which can resist acidity, alkaline resistance, and organic solution.3. heat resistance: graphite block is one of the most heat -resistant raw materials that are already known to today. Its dissolution point is 3850 ℃ ± 50 ℃, and the melting point is 4250 ℃. Discard the least, and discard 0.8%according to weight graphite. It is not difficult to see that the heat -resistant function of graphite is excellent.4. Wetness: The moisturizing function of the graphite is similar to sulfide, and the friction resistance is lower than 0.1. Its moisturizing function changes with the size of the fish scales. The larger the fish scales, the smaller the friction resistance

Popular Science Knowledge of Graphite Crucibles

Crucibles can be divided into three categories: graphite crucibles, clay crucibles, and metal material crucibles. In graphite crucibles, there are three types: regular graphite crucibles, irregular graphite crucibles, and high-purity graphite crucibles. Various types of graphite crucibles differ in performance, main uses, and application standards, resulting in differences in commonly used raw materials, production methods, production processes, and product specifications and models.The main raw material of graphite crucible is pure natural graphite in crystalline form. Therefore, it maintains the various physical and chemical characteristics of pure natural ink.Namely, it has excellent thermal conductivity and heat resistance, and has a small coefficient of linear expansion throughout the high-temperature application process.

Graphite special nature

Due to its special structure, graphite has the following special nature:1. High temperature resistance: The melting point of graphite is 3850 ± 50 ° C, and the boiling point is 4250 ° C. Even if it is burned by ultra -high temperature arc, the loss of weight is small and the thermal expansion coefficient is small. Graphite strength is strengthened with the temperature, and at 2000 ° C, the graphite strength doubles.2. Conductive and thermal conductivity: The conductivity of graphite is 100 times higher than that of ordinary non -metal ore. Thermal conductivity exceeds metal materials such as steel, iron, and lead. The thermal conductivity decreases with the temperature increase, and even at a very high temperature, the graphite becomes the heating body. Graphite can conduct electricity because each carbon atom and other carbon atoms in the graphite only form three co -price bonds, and each carbon atom still retains a free electron to transmit charge.3. Lubrication: The lubrication per
