Graphite electrode
1. Working conditions: The sintering process requirements for hot-pressed diamond geological drill bits are as follows: The temperature should reach 1000℃±20℃, the forming pressure should be between 16 and 18 mpa, the holding time should be 4 to 7 minutes, and the environment should be in a non-vacuum state. Under this working condition, the graphite mold used for forming and heating functions is required to have a high density, sufficient mechanical strength, high resistivity, high purity, strong oxidation resistance and low porosity, so as to ensure the excellent performance, dimensional accuracy and long service life of the hot-pressed diamond geological drill bit.
2. The current situation of graphite molds for domestic hot-pressed diamond geological drill bits Since the 1970s, domestic graphite molds for hot-pressed diamond geological drill bits have generally been processed with high-purity graphite bricks. Through continuous selection, research and development, and improvement, their main technical performance parameters can basically meet the requirements of the hot-pressing sintering process. However, compared with the current international advanced level, there is still a considerable gap. This requires the continuous efforts of our technical professionals. We hope that our hot-pressed diamond geological drill bits will get better and better. In fact, graphite powder has many handy uses in our daily life. Let’s have the editor tell you about them today
Graphite powder
Graphite powder is commonly used in industrial production, but it also has uses in daily life. Here is a brief introduction to some useful uses of graphite powder in daily life. Graphite powder is a natural lubricant. It has good self-lubricating properties by itself, and when processed into very fine graphite powder, its lubricating properties are even better. Thus, it can be made into graphite powder lubricants for lubrication and so on.
Where are graphite powder lubricants used in daily life nowadays? It is the most common door lock.
Graphite electrode
The car lock has been activated. As the door lock and other components have been used for a long time, the lock core will react with the air and other factors, causing rust. This can lead to difficulties in turning the key, plugging and unplugging, and unlocking. I believe many people have encountered such situations. Nowadays, many lock-picking institutions and lock maintenance personnel recommend lock core graphite lubricant. This lock core graphite lubricant is designed to address issues such as difficulty in turning the lock core, preventing it from being forcefully twisted during the key’s rotation, which would eventually lead to the need to disassemble or replace the lock, causing great hassle. Nowadays, many households have lock core graphite lubricants at home to maintain the lock core, but many people do not. This is the so-called practical use of graphite powder in daily life.
The lock core graphite lubricant contains special graphite powder for lubrication. But it doesn’t matter if you don’t have it. You can find a pencil and use a small knife to scrape some very fine pencil lead powder. Because nowadays pencil leads all contain graphite powder, and graphite powder is all lubricating. The disadvantage is that it is time-consuming and troublesome, and the purity of the graphite powder is not pure and it contains other components. The lubrication effect is not as good as that of the lock core graphite powder lubricant, and it is also very troublesome to operate. It is not as simple as the lock core graphite powder lubricant.
