Applicability of waterborne insulating varnish and motor
Insulating varnish is an important insulating material in the motor production process. It not only involves the motor production and processing process, but also the upstream materials of the motor products. Whether it is for the environmental protection itself or for the occupational health and safety of the operator, the safety and environmental protection of the insulating varnish. It is an inevitable irreversible trend.
At present, the traditional solvent-based insulating varnish used by various motor manufacturers in China contains a large amount of flammable, explosive and toxic solvents such as benzenes and ketone esters. After construction, a large amount of harmful substances are volatilized, which threatens human health and pollutes the environment. Therefore, it will gradually be replaced by water-based insulating varnish. However, for the users of insulating varnish, there are some blind spots for understanding the water-based paint and the process requirements of the later use process, which requires a deeper understanding and running-in. Ms. Participate in the simple exchange of water-based insulating varnish with everyone today.
What is waterborne insulating varnish?
Waterborne insulating varnish refers to insulating varnish with water as the main solvent. Waterborne insulating varnish includes water solubility and water emulsion. Waterborne insulating varnish will have some adverse reactions in the case of improper disposal, mainly in:
(1) The polar group of the water-based paint should be reduced to a lower level during the curing process of the insulating paint. Otherwise, the hydrolysis in the humid environment will seriously affect the insulation performance and mildew resistance of the paint film;
(2) The corrosiveness of water or ionic groups to metals may constitute damage to metal parts to varying degrees. The anti-flashing technology is used in the manufacturing process of the paint to solve the corrosion of the metal parts to a certain extent, but at the same time, the insulation performance of the cured product is lowered.
(3) The mechanical strength and bond strength are worse than those of traditional insulating varnish. Under the action of electromagnetic force and mechanical stress, the winding may be loose or deformed.
