Identification of the Quality and Chemical Properties of Graphite Plates
Ⅰ. How to distinguish the quality of graphite plate?
Graphite plates are no strangers to some manufacturers, but in fact, many manufacturers have used them for more than ten years, but they don't know how to distinguish the quality of graphite plates, some manufacturers say it is particles, and some say it is formula.
In fact, this is just a generalization of the product, very general. When it comes to how to distinguish the quality of graphite plates, there is only one key point, that is density. The importance of density in the application of graphite plates is explained from the following aspects.
1. In the electroplating and electrolysis industries, many manufacturers only value the conductivity and price of graphite plates, but sometimes ignore the important density.
Because if the density is low, pores are prone to appear on the surface, and penetration in the electrolyte is prone to occur, which will cause the graphite plate to oxidize and fall off, resulting in a greatly shortened service life. If the density is high, the cost of use will increase, so it is very important to choose a suitable graphite plate manufacturer.
2. In the wear-resistant industry, graphite plates are mainly used in the form of backing plates to play a lubricating role, where the density of graphite plates is greatly revealed.
The physical structure of the graphite sheet with low density is not tight, it is easy to fall off during use, and the surface is consumed too quickly. The service life of the graphite sheet with 1.56 and the graphite sheet with density 1.7 can be separated by 3 months.
In short, the quality of the graphite plate depends on the density, and only the graphite plate with the right density is a good graphite plate.
Ⅱ. Is the chemical stability of the graphite plate good?
Is the chemical stability of the graphite plate good? Compared with other materials, graphite plate has better chemical stability. Therefore, it can be widely used as an anti-corrosion structural material to replace ferrous or non-ferrous metal materials, especially stainless steel, and its effect is more significant.
The graphite plate is not subject to oxidation in the air below 400T. The graphite plate is very good in all chemical media except for strong oxidizing acids, such as nitric acid, oleum, chromic acid, aqua regia, carbon and other chemical media. Stablize.
Artificial graphite plate has unique corrosion resistance in chloride ion medium, and it has broad development prospects compared with expensive austenitic stainless steel, non-ferrous metals, and precious metals.
