Research on the application of water-based paint environmental protection coatings in coating.

Introduction
With the continuous improvement and reform of China's environmental protection regulations system, if the relevant personnel want to reduce the VOCs emissions of volatile organic matter, it must strengthen the development of water-based paint, and only in this way can we ensure the smooth development of follow-up work. It can be seen that now 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 paint belongs to a very small amount of organic solvent coating, which treats water as a thinner, and uses a small amount of low toxic alcohol ether organic solution, but also does not contain toluene, xylene and other harmful substances . In general, the organic solution of water-based coatings needs to be kept between 5% and 15%, which has a very important role and effect on reducing pollution and saving resources, and can even improve the surrounding working environment and reduce air pollution.
Water-based paint environmental protection coating application recommendations and countermeasures
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, then the direct water-water primer adhesion will affect, in severe cases, will also cause other coating defects. Therefore, in the actual work process, the relevant personnel should appropriately increase 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.
To strictly control the temperature of the paint room and drying room
with the constant changes in temperature and humidity, the evaporation rate of water will also be affected by the temperature and produce a certain degree of fluctuations, so the relevant personnel 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, so the temperature and humidity throughout the year is also difficult to meet expectations to go, so it is very critical to increase the water paint construction temperature air conditioning system. Because of the poor coating conditions in heavy machinery and other industries, the temperature in the room is constantly raised, so as to speed up the increase of moisture, so as to effectively avoid the emergence of various problems.
To strengthen the paint room and drying room corrosion protection
by comparison, the original mechanical coating production line is to 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. However, in the future, it is possible to avoid the corrosion of water-like paint on other parts, and the function area, the chamber wall panels of the paint room, etc. need to be anti-corrosion treatment, so as to ensure the smooth development of follow-up work. For example, in the production line planning and design, investment conditions should be used as far as possible stainless steel materials, such as financial constraints must be anti-corrosion treatment.
