Problems solved by technology

[0002] With the improvement of people's living standards, all kinds of household appliances involved in life are constantly being updated to meet the various requirements of consumers. Microwave ovens exist in every household and are closely related to our lives. Microwave ovens need Powder coatings have relatively high requirements, but most of the powder coatings used in microwave ovens in the prior art have the following problems: 1) poor high temperature resistance and poor bacteria resistance, 2) powder coatings used in microwave ovens in the prior art contain solvents , which pollutes the environment a lot, and has certain potential safety hazards; therefore, a new technical solution is urgently needed to solve the above technical problems
