water-based resin | water-based industrial coating (a) water paint common problems Water - based paint common problems: bubble - microbubble Microbubbles are tiny bubbles. If there are microbubbles in the varnish layer, this will reduce the "warmness" of the wood. Each microbubble appears to be a small curved lens that reflects and refracts light, summing up, resulting in a yellow and red color reduction on the surface of the wood without increasing transparency. Microbubbles are difficult to remove with antifoaming agents because the microbubbles have low buoyancy and cannot float to the surface. A foam that does not float to the surface cannot be broken by a commonly used defoaming agent. The elimination of microbubbles is absorbed by the surrounding liquid by the microbubbles. Microbubbles can be controlled in the following ways: 1.Control the solid content of the coating High solid content and high density of microbubbles. In a water-based coating, high solids content means less water. If there is less water, the air bubbles will absorb less water. High solid content means less drying time and less bubble dissipation. The difference between 2-3% solids results in a difference between having microbubbles and having no microbubbles. 2.Pay attention to the substrate you are painting A highly absorbent substrate takes water from the first layer of paint it is coated with. This will make the first layer of paint month than later coated with other paint hydroxylamine more easily into hydroxylamine. However, the shortened waxing time and the hydroscopicity of the lignin matrix will increase the probability of producing microbubbles on the hydrophobic substrate of the first layer of lamine hydroxylamine. Maple and birch have more frequent microbubble problems than oak and ash, which are denser. By reducing the solids content of the first coat, the density of the microbubbles is reduced.For example, if the solid content of the primer is reduced from 30% to 27%, this will reduce the number of microbubbles in the primer hydroxylamine. After the substrate surface is sealed with a first coat with a low solid content, subsequent coats may have a higher solid content. 3. Pay attention to the surfactants used in water-based paints Carefully use additives with high surfactants. A small amount of surfactant will cause more microbubbles. Acetylene diol surfactants such as defoamers [do not appear to cause microbubble production and can be used as a substitute for surfactants. 4.Pay attention to the solvents used in water-based paints Solvents can affect the concentration of microbubbles. In some cases, the use of buty1 cellosolve and buty1 carbitol increases the density of the microbubbles of the treated paint film. 5. Pay attention to the adhesion of water-based paint The adhesion of waterborne coatings determines the formation of initial microbubbles. In the process of coating, the larger the number of microbubbles is when the coating is still wet, the more m...

water-based resin | water-based industrial coating (a) water paint common problems Water-based paint common problem: bubble - big bubble Large bubbles are large, visible bubbles that are visible to the naked eye. Bulk bubbles generally occur during the production or application of water-based paints. Possible solutions: 1. Use appropriate defoaming agents In the process of producing water-based paint, when a large amount of air is stirred into the water-based paint,large bubbles may be generated. The addition of a highly effective defoamer to the stirred bottom material serves to remove these large bubbles.These highly effective defoamers are generally able to withstand the effects of cutting during agitation. Continue to work during the agitation process to eliminate foam. Moreover, the agitation process can reduce the chances of these highly effective defoamers eventually causing defects on the surface of the aqueous paint film. In general, highly effective defoamers are not suitable for use with any of the diluents, and defoamers for "quick-acting" defoamers should be used. Defoaming agent can also be "in the tank" defoaming. When choosing antifoaming agent, the balance between the durability of antifoaming agent and the reduction of defects on the surface of waterborne paint film should be considered. Non-silicone defoaming agents cause less side effects of surface defects, but their durability is also poor. In addition, some defoaming agents will cause surface defects of water-based paint film at the beginning,but if you wait 24 hours, let it fully react with the paint, they will cause defects of water-based paint film surface will be reduced. 2. Minimize the surfactant caused by foam. Anhui zhong 'en water-based paint raw material products have a very low tendency to produce large bubbles.One of the reasons for this is the low content of surfactant in the water based paint products of zhongen chemical industry.

Water-in-water multi-color paint spray guns to use most of the spray, for the operation, but also because of the improper use of the gun caused by uneven distribution of the coating, the following together to see how to solve it. The smaller the gun distance, the greater the pressure of the spray, the greater the impact of the product by the pressure of the water, water-in-water colorful paint coating will appear uneven situation, resulting in smearing too thick problem; Gun distance, spray pressure small, easy to drain  paint, so that part of the material is too much spray, smear not reach the specified thickness. Spray the fan and the painted surface is presented in a vertical state. Manual spray gun, the spray width can not  appear toolarge,otherwise there  will be uneven coating problems. Spray gun operation should always be parallel  with the coated surface,perpendicular to the spray fan, the operation rate is  unstable, the coating thickness is not uniform, the operation rate is too fast, the coating is too thin and the running speed is too slow. Different spray details of different patterns, after the construction, some of the things still need to improve the end of the patch,paint and help equipment to clean up, after the use of residual paint to block the reservation, which is the  need to pay attention to the problem. Note: the construction of the way and the density will directly affect the final stone effect.
