Boss Liu is a manufacturer of waterborne paint lines in Nanchang. Waterborne coatings are more popular today because of more environmental protection and safety. At the same time, because of the slow evaporation of water, the drying speed of waterborne coatings is slow, which greatly reduces the work efficiency. Liu has tried natural drying, hot air drying and infrared drying before, these schemes have slow heating rate, external drying and internal drying, resulting in the residual moisture of the film to reduce water resistance and pollution resistance, because these methods are external heating and drying, only after the heat transfer of the product itself can slowly infiltrate into the interior of the material and gradually heat up and dry. As the current drying methods are not satisfactory, so customers on the Internet to understand the microwave technology, with a try attitude, Liu contacted us.

Water-Based Paint
Liu sent some materials and we did the related drying experiment. The experiment found that the microwave drying temperature is fast, but it is easy to deform the dry matter, especially for plastics and wood products, so how to solve the problem?
Through experiment and comparison, infrared ray has good penetration to the object, infrared radiation wants to be heated inside the film from the outside of the film, the heating time is short, the heating is uniform, the moisture volatilization is smooth, and no pores, bubbles, markings and other defects are produced. Combined with the effect of microwave, microwave is heated from the inside. And if we use two kinds of colloid drying, we can give full play to the advantages of the two drying methods, showing that the infrared drying from the outside of the film to the internal heating, can quickly evaporate 60% of the moisture, while microwave drying can ensure the heat diffusion of the film from the inside to the outside, the residual moisture in the film wants the coating to show diffusion, and quickly remove the residual moisture in the film, especially the combined water. These two drying methods combine to give full play to their respective advantages, overcome each other’s shortcomings, reduce energy consumption, and solve the problems of variable lines at the same time.
microwave and infrared drying equipment
Liu appreciates the effect of our experiment, and hopes that we will go to the factory as soon as possible to measure, because our microwave and infrared equipment should be designed on the existing assembly line, that is, to design a new microwave and infrared drying system on top of the current transmission system.
Liu said this is a very large market, this time if we break through this technical problem, we need a large number of microwave and infrared drying equipment upgrading in the future, looking forward to in-depth cooperation in the future.
