Recommendations for the application of water-based paint environmentally friendly coatings in coatings.

With the continuous improvement and reform of China's environmental protection regulation system, in order to reduce the VOCs emissions of volatile organic matter, it is necessary to strengthen the development of water-based paint, and only in this way can we ensure the smooth development of follow-up work. Nowadays more and more construction machinery enterprises began to apply water-based paint, and in the future social development, water-based paint will gradually replace oily paint, which will become the inevitable trend of future industry development. On the other hand, water-based coatings play a very important role and effect in reducing pollution and saving resources, and can even improve the surrounding working environment and reduce the pollution

Water-based environmental protection coating in the application of recommendations and countermeasures
First, pre-treatment transformation measures
We all know that heavy machinery industry, construction machinery, etc. belong to the largest number of structural parts used in the production enterprises, but the pre-treatment coating conditions are not very ideal, especially in throwing Prior to the pill, the relevant personnel will not deal with the residue of various chemicals, but these work pieces after the projectile, once the residual chemicals have not been cleaned up, it will directly affect the adhesion of water-dependent primers, in serious cases, other coating defects. Therefore, in the actual work process, should be appropriately increased chemical residue cleaning equipment, such as steam cleaning, spray cleaning, drying equipment, etc. , if it is not possible to increase equipment or retrofit the site, then it is necessary to carry out manual cleaning. Secondly, in the new coating production line, staff must increase the residual chemical treatment process, so as to avoid the treatment and then carry out various links of cleaning, thereby affecting the overall efficiency of work.
2. To strictly control the temperature of the paint room and drying room
With the constant change of temperature and humidity, the evaporation rate of water will also be affected by the temperature and produce a certain degree of fluctuation, so only strictly control the temperature and humidity of the paint room, so as to avoid pinholes, hanging and other problems. In general, the mechanical industry on the paint room temperature requirements will be controlled between 20 degrees C-30 degrees C, and humidity should be maintained at about 30%-70%, because the mechanical coating line is not installed air conditioning system, the temperature and humidity throughout the year is also difficult to achieve the desired effect, so it is also very critical to increase the water-type paint construction temperature air conditioning system. Only by reaching the right temperature and humidity can the increase of moisture be accelerated, thus effectively avoiding all kinds of problems.
Thy, to strengthen the paint room and drying room corrosion-resistant
by comparison found that the original mechanical coating production line is water curtain-type spray paint to expand, and often contact with water grooves and other materials are stainless steel, and only in this way to meet the water-based paint on the material requirements. Effectively avoid corrosion of other parts, functional areas, paint chamber wall panels, etc. need to be anti-corrosion treatment, so as to ensure the smooth follow-up work.
