Insulation paint varieties are suitable for different solvents (thinner), but commonly used xylene and No. 200 solvent gasoline
Insulation paint varieties suitable for solvent (thinner) is also different, but commonly used xylene and 200 solvent gasoline, note that they are flammable, tell us about the method and reason for dipping paint, processing the finished transformer to pre-bake temperature deterrence of 105 degrees because lower than 100 degrees water can not be gasified can not withdraw the bottom drying, about 4 hours baking (theory requires regular measurement of insulation resistance, when the resistance is no longer increasing, it is good), and then the temperature down to 60 degrees after dipping into the paint, such as the temperature is too high so that the solvent in the paint evaporates too much so that the paint viscosity is too high next time is not good, due to the transformer 60 degrees dipped into the paint temperature will be reduced, the transformer in the gap to form a negative pressure paint will automatically flow, the paint does not bubble after waiting a bit and then take out the drop of dry paint and then dry, if the quality requirements are high, after the first dip paint drying and then dip a paint drying, the first dip of the paint requires low viscosity in order to The first dip of paint requires low viscosity to flow into the transformer, the second dip of paint requires high viscosity to form a paint film on the transformer surface.
