Common blackening problems of Vientiane shaft

In people's daily work and production, machinery and equipment are indispensable good helpers. However, slowly, with the prolonged use of mechanical equipment, we will find that the equipment slowly begins to have some problems. Such as wear and tear of mechanical surfaces, damage to parts, etc. Today, let's take a look at the problem of "common blackening of the Vientiane axis".

In fact, there is a common sense that we need to understand first, that is: the Vientiane axis is more prone to blackening after a period of work, although this "blackening phenomenon" has a certain impact on its appearance, it does not look so beautiful. But in fact, blackening means that a protective film has been produced. And this protective film is the key to determining the quality of the Vientiane axis.

Therefore, in the process of use, we found that the Vientiane axis has blackened signs, so don't worry too much. In use, the universal joint shaft should be naturally blackened, and a good blackening speed should be maintained. Some people may ask "why is the blackening speed of the Vientiane axis slow"? That is because there are many factors affecting it. In order to avoid this situation, we have sorted out the following three factors:

1) Copper sulfate will also increase the blackening speed of the cardan shaft, but the content of copper sulfate should not be too much, too much copper sulfate will cause the quality of the blackening layer to be loose.

2) The content of the complexing agent is not easy to be too much, because too much will affect the blackening speed of the cardan shaft. In order to change this situation, the amount of the complexing agent should be controlled as much as possible. Of course, the existence of the complexing agent is also important. Indispensable.

3) The speed of blackening should not be too fast, it is best to control it within 3-8 minutes, so that it can not only achieve a good blackening depth, but also better in corrosion resistance.

To sum up, the phenomenon of blackening of the universal joint shaft is actually very normal, as long as we pay more attention to it in normal use.
