Why does the friction plate become sticky?
After the friction plates have been left stationary for a long time, you will find that the friction plates stick together. You don’t need to worry at this time, because the friction material in the friction plates is a high-molecular polymer, which contains rubber components, especially when the weather is hot. There may even be stickiness, but this does not affect normal use at all.
If the friction plate in the brake is sticky, it is because the brake maintains static pressure for a long time, the surface is easily affected by moisture, or the internal air is squeezed out to form a negative pressure state, showing sticky characteristics. The principle is similar to plastic suction cups used for glass or wall hooks. This phenomenon is a normal phenomenon after being left for a long time. It may need to be manually released when installing the machine (generally it can be opened when the motor is started). Generally, it will fall off with a small twist. Secondly, this phenomenon will disappear after the motor is running and running in. Or tap lightly to make them fall off. In normal use of the motor, because the static pressure time is short, and the sticky components of the rubbed surface during use will react thermally to produce a more stable hardened layer, the friction plate will not stick.
