Common knowledge of paint: advantages and disadvantages of waterborne paint

Core tip: in recent years, due to the increasingly serious air pollution, waterborne paint has become the main force in the coating industry The advantages and disadvantages of water-based paint are analyzed as follows: firstly, water is used as solvent in water-based paint, which saves a lot of resources and greatly reduces the potential fire hazard during construction; the air pollution is also greatly reduced A small amount of low toxic alcohol ether organic solvent was used to improve the working environment The organic solvent of general water-based coating is between 15% and 15%, while the current cathodic electrophoretic coating has been reduced to less than 1.2%, and the effect of reducing pollution and saving resources is obvious Secondly, the water-based coating on wet surface and wet Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: in recent years, due to the increasingly serious air pollution, waterborne paint has become the main force in the paint industry The advantages and disadvantages of water-based paint are analyzed as follows: firstly, water is used as solvent in water-based paint, which saves a lot of resources and greatly reduces the potential fire hazard during construction; the air pollution is also greatly reduced A small amount of low toxic alcohol ether organic solvent was used to improve the working environment The organic solvent of general water-based coating is between 15% and 15%, while the current cathodic electrophoretic coating has been reduced to less than 1.2%, and the effect of reducing pollution and saving resources is obvious Secondly, the water-based coating can be directly applied on wet surface and humid environment, which has low requirements for the drying degree of the material surface and strong adhesion of the coating Then the coating tools can be cleaned with water, and the consumption of cleaning solvent is greatly reduced Finally, the electrophoretic coating film is even, flat and well flattened, and each part can be coated with a certain thickness of coating film, which has a good protection The electrophoretic coating has strong corrosion resistance Disadvantages: first of all, the water-based coating has high requirements on the construction process and material surface cleanliness Due to the large surface tension of water, dirt is easy to cause shrinkage of the coating Secondly, the dispersion stability of water-based coating against strong mechanical force is poor When the velocity in the pipeline changes rapidly, the dispersed particles are compressed into solid particles, making the coating produce pockmarks The shape of the conveying pipe is required to be good, and the pipe wall is free of defects Once again, the water-based coating is corrosive to the coating equipment, which requires the use of anti-corrosion lining or stainless steel materials, so the equipment cost is high Stainless steel pipe is also required for corrosion and metal dissolution of water-based coating to transmission pipeline, which makes dispersed particles precipitate and coating produces pockmarks Then the baking type water-based coating has strict requirements on the construction environment, which increases the investment of temperature and humidity regulating equipment, and also increases the energy consumption Finally, the latent heat of water evaporation is large, and the baking energy consumption is large The cathodic electrophoretic coating needs to be baked at 180 ℃, while the latex coating has a long drying time The organic cosolvent with high boiling point produces a lot of oil smoke during baking, which drips on the surface of the coating after condensation and affects the appearance Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
