Vacuum impregnation machine requirements for viscosity of dipping paint

Vacuum impregnation machine requirements for viscosity of dipping paint

The vacuum impregnation machine is for immersion paint of electronic product transformer. The electronic transformer impregnated with insulating varnish can improve the electric strength and insulation resistance of the transformer insulation system to improve its electrical insulation performance and meet the electrical insulation performance requirements of the transformer. However, the viscosity of the immersion paint using vacuum impregnation machine is an important technical index of the impregnating varnish. The following is a detailed explanation of the viscosity requirements of the vacuum impregnation machine.

  The vacuum impregnation machine  viscosity of the immersion paint is as follows: Coating-4 Viscometer, 25 ± 1 ° C, 25-45 seconds or 30-60 seconds. However, the viscosity index of the impregnating varnish and the dipping of the electronic transformer dipping process are sticky.
Degree is not the same. According to the different electronic transformer products, the requirements for the viscosity of the dip coating are not the same. For products with tight structure requirements and good permeability, the viscosity of the immersion paint is better. The viscosity of the enamel paint is a coating-4 viscometer, 25±1°C, about 20 seconds. Some products only need about 15 seconds. The viscosity is adjusted by special thinner. For products that pay attention to the amount of paint, the viscosity of the dip paint is better. The viscosity of the dip-like paint is coated with -4 viscometer, 25±1°C, 40-60 seconds. Some manufacturers even use 80. - 120 seconds of paint to dip paint. In order to increase the amount of paint, it is also solved by the method of secondary dipping.
