Water bag sand, water bag colorful easily appear what problem?

Exterior wall decoration is a house coat. It is beautiful, durable and select material are closely related. Today, when the coating is widely used in exterior wall decoration, water package of water and sediment and water bag is becoming more and more popular. However, in the application of the above-mentioned material, must pay attention to the following aspects: 1. Layered stratification refers to the finished product barrels of internal: 1. To protect the emulsion in the upper, and glue color particles sink into the bottom. This product paint must be in construction process, it will damage the particles, affect the definition of color dot, and will inevitably cause color mixing, which directly affect the stability of the product. (2) some particles floating in the protection and the emulsion surface glue, direct contact with air, in the particle surface with a layer of protective film, affect the uniformity of coating and machinability. 'Solution' should be based on color dot particles and protect the proportion of colloidal solution and emulsion thickener and a series of chemical synthesis and physical function related to control, such as the compatibility of them, overlapping, and proportion. Better protect the adhesive has excellent suspension function and package. two Penetration color really paint protection adhesive solution dispersion medium is obvious with color particles mutual penetration, adhesion and color color points not clear. In particular, when the base paint and color mixing, and then use protection rubber granules, granular ooze. In addition, the continuous phase has more bleeding and color mixing, this does not guarantee the original particle size, emulsion adhesive protective medium into a turbid liquid in ivory. The protection of the adhesive solution to replace instability. ( Click to understand protection glue choice) two Permeability colored water bag sand and finished water bag water coating of flocculation, batt form colloid formation, not easy to put all the color particle dispersion and packages in it. Particles and continuous phase into jelly, no viscosity values, the finished coating cannot be used. Solution (1) should choose better silicone acrylic emulsion. two Penetration (3) to protect the choice of adhesive performance is good, wide scope of application in integral formula and production. 4. Colored particles bleak. The finished paint have boiled effect. The color of the particles is not straight, the mixture of particles was not clear. After construction, color particle is fuzzy, no stone effect. Because most of cellulose thickener, defoamer, and some kinds of pigments have extinction effect. Usually white particles have better gloss, and other color of poor luster. Solution to solve the color particle dim and dark, in the production formula, protect glue should contain paste, and should be tolerated powder ( Such as titanium dioxide, sand and packing) To ensure that the mixed color of color points clearly visible. two penetration
