With the pressure of environmental protection policies, consumers' environmental awareness has been continuously improved, and the requirements for painting have become higher and higher. Painting should not only ensure good corrosion resistance, high decorative performance, high construction performance, but also use good performance materials and processes to reduce the emission of volatile organic compounds, which brings opportunities for the development of environmentally friendly coatings such as water-based paints. Water-based paint uses water as a solvent, which is harmless to the human body and has a significant effect on reducing pollution and saving resources.
There are many ways to dry water-based paints. Different drying methods have significant differences in the drying speed and film-forming quality of water-based paints. Taking the water-based paint drying of furniture as an example, natural drying has the advantages of simple method and common application, but at the same time has the drawback of slow drying speed. Under natural conditions, temperature and humidity and wind speed are varied, and drying speed and film formation quality are unstable. If the temperature is high or high humidity or the humidity is relatively large, the coating tends to be white and the drying speed is slow; the infrared drying has the advantages of fast curing speed, rapid temperature rise, good curing quality, etc., but when drying the coating by infrared heating, coating The layer has a distinct temperature gradient, and its drying is extended from the surface to the inside, which makes it unsuitable for drying thicker coatings; UV-based paint drying is more suitable for flat panel furniture, while the furniture industry has a three-dimensional structure. Many characteristics, so the UV drying method has considerable limitations in the furniture industry.
