Problems often faced in water-based paint spraying
1. The spraying of water-based paint has high requirements for spray gun atomization technology. In order to create a beautiful water-based paint film, the particles, pearlescent powder, metal silver powder and other components in the water-based paint must be fully atomized through the spray gun to make them arranged neatly and evenly distributed. Moreover, the price of water-based paint is relatively high. Excellent spray gun atomization will reduce the rebound of paint, improve the paint transfer efficiency, and meet the requirements of cost saving and green environmental protection. Therefore, the ideal water-based paint film has very high requirements for the atomization technology of the spray gun.
2. The drying of water-based paint is slow. The drying of water-based paint will be affected by temperature, humidity and wind speed. If it is at high temperature, high humidity or low temperature, the drying speed will be very slow. To accelerate the drying speed of water-based paint, in addition to increasing drying and dehumidification equipment and corresponding measures to adjust the formula of water-based paint, the sufficient atomization degree of spray gun will also affect the drying speed of water-based paint.
3. Corrosivity of water-based paint water-based paint has certain corrosivity to metal. If the equipment used does not have corrosion resistance, it may affect the final paint film effect and will be replaced frequently due to equipment damage.
Through the analysis of several key characteristics of water-based paint, it can be seen that it is still difficult to obtain the ideal film effect of water-based paint. Therefore, the selection of spray gun is more important
1、 The water-based paint can be fully atomized and the particles are evenly arranged to form a high-quality water-based paint film and accelerate the drying of the film.
2、 Stable performance to avoid paint film defects during spraying.
3、 It has excellent paint transfer efficiency to reduce the waste caused by excessive spraying of water-based paint and a large number of paint mist rebound, which is conducive to obtaining a plump paint film effect.
4、 The material and design structure of core components need to be corrosion-resistant and easy to clean.
