How to identify the quality of graphite board

The graphite board is not rusty for some manufacturers, but in fact many manufacturers have applied for more than ten years, and they are unclear how to distinguish the quality of graphite boards. This is only a kind of summary of the product, which is very vague.Speaking of how to distinguish the advantages and disadvantages of graphite boards, there is only one key, which is the relative density. The following discusses the necessity of using the Moore quality formula from many levels.The battery electrolyte is very prone to infiltration, resulting in the oxidation of the graphite board air, which is greatly shortened by the use period. The density is high, and the cost of application is increased, so it is important to choose a suitable graphite board manufacturer.2. In the field of resistance, the key to the graphite board is used to pad the method, which has a moisturizing effect. The relative density of the graphite board here is greatly displayed. Very easy to fall, the surface

How to use expansion graphite

1. Protective useExpansion graphite can be used as protective materials, which can be used to protect metal and other damaged objects, such as circuit boards and steel. Because expansion graphite can expand 10 times, it can effectively block the flames and make these objects from burning with flames.2. InsulationExpansion graphite can also be used as insulation materials, because it has good thermal resistance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing the loss of heat, thereby playing the role of heat preservation.3. Filtering useExpansion graphite can also be used as filtering materials, because it has adsorption and can be used to adsorb toxic substances, such as pollutants used in water treatment, which can effectively remove pollutants in water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement useExpansion graphite can also be used as r
