Viscosity and temperature of vacuum impregnating equipment

The control of viscosity and temperature plays a vital role in the control of vacuum impregnating equipment.

Next, let me know how to control the viscosity and temperature of vacuum impregnation equipment.

1. The viscosity of the paint should be suitable. When the first vacuum dip is set, the paint is expected to penetrate into the winding, so the fluidity of the conditional paint is better. Therefore, the viscosity of the paint should be lower, usually 22-26s (20 C, No. 4 viscometer) can be obtained. When the second vacuum dip is set, the first expectation is that the winding will become a better layer orally. The viscosity of the paint film should be poor, usually 30-38 s. Since the temperature of the paint has a poor effect on the viscosity, it is usually designated as the base temperature of 20 C, so the temperature of the paint should be used as a suitable adjustment when measuring the viscosity.

2. Vacuum dipping setting dipping temperature If the workpiece temperature is too high, the solvent in the paint quickly volatilized, so that the winding oral premature into film, and difficult to penetrate into the inside of the winding, also turned into a gimmick throw; If the temperature is too low, lost the pre-baking use, so that the viscosity of the paint is poor, poor fluidity and permeability, but also the vacuum dipping setting dipping effect is not good. Practice has proved that when the workpiece temperature is 60~80, the vacuum dip paint is suitable.

This is our machine for you to set up the vacuum dipping paint viscosity and temperature control steps.
