Water package features colorful coating and construction problems

Water bag (colorful coating 水- - - - - - 在- - - - - - 水颜色漆) Is a kind of water as solvent or dispersion medium, after a paint coating can get colorful patterns. It is a kind of green building coating, not only conforms to the requirement of environmental protection, energy conservation, and give a person a kind of elegant and magnificent, variety of feeling. Novel, it has the potential to, comply with the coating is the development direction of the future. Aquatic products represented by DAD system of water technology is quite mature products. A, water bag water features colorful coating water bag water important attribute is colorful coating, their color patterns can be obtained after a coating, because the paint is composed of two immiscible phase, a phase is dispersed phase, and the other phase is continuous phase ( Dispersion medium) 。 Dispersed phase consists of two or more different sizes of nonferrous particles, and they contain stabilizers evenly suspended in dispersing medium and in a stable state. Usually, the color will not disappear or change. Metope adornment, with a special gun one-time spraying water-based paint, water-based paint in all sorts of color particles can form a variety of overlapping but have independent color color effects, similar to the natural granite. 2. Water bag colorful coating, prone to the problem of 1. Storage problem because the water bag water color paint is composed of the dispersed phase and continuous phase, the two phase between relatively insoluble form the water bag of colorful coating products. However, due to the proportion of different systems or improper viscosity control, when the long-term storage, dispersed phase sinks, sometimes meet continuous rise, lead to water storage after floating colorful coating layer phenomenon. 2. Cracking problems of water bag while the colorful coating coating has the characteristics of cracking resistance, but can not be used alone to achieve adornment effect. Metope need to adopt a series of reasonable construction technology, such as selection of anti-cracking performance of leveling mortar, alkali resistant, alkali resistant primer, reinforcing materials, weather resistance, intermediate paint, etc. 3. Construction equipment problems due to water bag water color paint for coating equipment, especially iron equipment has certain corrosion resistance and adhesion, easy to dissolve in the pipeline, metal isolated dispersed particles, and produce pitting on the coating. In addition, the water bag water dispersion stability of strong mechanical force colorful coating, when the velocity changes in the pipeline rapidly, dispersed particles are compressed into solid particles, cause pitting coating. 4. Stability effect due to water bag colorful coating, water of high volatile strongly depends on the environment of water, in a low humidity environment can quickly dry, sometimes resulting in crack; In high humidity environment, the film-forming process will be very slow, it is easy to cause the coating sagging. In addition, the new formation of the coating are usually very sensitive to water, the increase of the content of water vapor in the air can lead to coating wrinkling.
