Graphite electrode 1. Working conditions The sintering process requirements of the hot-pressed diamond geological drill bit: temperature reaches 1000℃±20℃, molding pressure is between 16～18MPa, heat preservation time is 4～7min, the environment is non-vacuum. Under this working condition, the graphite mold used for forming heating function is required to have greater density, sufficient mechanical strength, higher electrical resistivity higher purity, strong oxidation resistance, low porosity. This ensures the excellent performance, dimensional accuracy long service life of the hot-pressed diamond geological drill bit.
2. The current status of graphite molds for hot-pressed diamond geological drills in China Since the 1970s, domestic graphite molds for hot-pressed diamond geological drills have generally selected high-purity graphite bricks for processing. After continuous selection, development improvement, the The main technical performance parameters can basically meet the requirements of its hot pressing sintering process. However, compared with the current international advanced level, there is still a big gap. This requires the continuous efforts of our technical professionals, we hope that our hot-pressed diamond geological drill bit will get better better. In fact, graphite powder has many magical uses in our lives. Let me tell you the specifics today.
Graphite powder is often used in industrial production, but in life, graphite powder is also useful. Here is a brief introduction. The life of graphite powder is very useful. Graphite powder is a natural lubricant. The self-lubricating property of graphite powder itself is very good. Good, but processed into very fine graphite powder, its lubricity is better, so that it can be made into graphite powder lubricant for lubrication.
are graphite powder lubricants used in daily life? Is the most common door lock,
The car is locked, because the door lock waits for a long time, the lock cylinder will react with air, etc., rust will occur, then the key will be difficult to turn, insert remove, unlock. I believe this situation, many people You will have encountered it. Now many unlocking mechanisms lock maintenance personnel will recommend lock core graphite lubricant. This lock core graphite lubricant is to solve the problem of difficult rotation of the lock core avoid the occurrence of strong twisting of the key during the turning process. It is very troublesome to be able to remove change the lock. Now many people have lock cylinder graphite lubricants in their families to maintain the lock cylinder, but many people do have it. This is the magical use of graphite powder.
The lock core graphite lubricant contains special graphite powder for lubrication, but it does matter if there is no one. You can find a pencil scrape some very fine pencil lead powder with a knife, because the current pencil lead contains graphite powder. Graphite powder is lubricating. The disadvantage is that it takes time effort. The purity of the graphite powder is pure contains other ingredients. The lubrication effect is as good as the lock core graphite powder lubricant, the operation is also very troublesome. It is as good as the lock core graphite powder lubrication. Agent is as simple as that.
