Water bag construction common problems and solutions

As the master of water wall material, water bag than other coating more colorful colorful coating, it is more convenient to construction. Simple coating can achieve unexpected adornment effect, is one of the best materials building exterior wall decoration and renovation. Recently, some customers complain water bag is not satisfactory. Through the investigation, summarizes the water bag in the construction of common four problems and solving methods. Now we share them: question 1: water bag water seepage water material bag coatings gradually presents the color particles with similar color, and cloudy with adhesive solution. Situation is not good, glue solution can appear flake condensation, seriously affect the stability of the effect of spraying and coating. Cause analysis: the main cause of this phenomenon is the color of gel particles protective film strength is not enough, the color of the pigment and filler particles break through the protective film, continue to infiltrate into plastic medium, turbidity and condensation. Solution: in strict accordance with the solvent than standard dilution, packaging color granules as soon as possible. If the color particle concentration is too high, should separate configuration to dilute the same density of adhesive solution. Keep temperature below 30 ℃, and stored at room temperature. Shall not use expired materials. Question 2: water bag water coating layer water bag water floating coating is mainly refers to some particles floating in the protection of the surface of the adhesive solution and form a certain thickness. After mixing floating coating color particles can temporarily uniform distribution in the adhesive solution, let stand after a period of time will still appear floating layer phenomenon. Floating layer evaporation and damaged packages in water-based adhesive protective film on the surface of the color particles, leak a lot of paint but cannot be used, resulting in unnecessary waste of cost. Water bag multicolor coating is a kind of stable suspension, required colour gel coating particles and liquid density between the same. If color gel particle density is greater than the liquid density, can appear floating layer, lead to crust scattered or hardening. If color particle density less than the density of adhesive solution, precipitation occurs, in serious cases, the color particles can't spit out. Solution: must be unified pigment concentration, maintain consistency with adhesive solution. If the specific dose not sure, you can small batch experiment was carried out, to ensure that the granular gel color particles can stably suspended in liquid. Question 3: water bag water color particles dim bag used in the process of preparation of a variety of additives, and some paint on the market most of cellulose defoaming agent, thickener and titanium dioxide with strong acid and strong alkali ingredients, easy to make color particles lose luster. Solution: to control the amount of titanium dioxide in the pigments and fillers question 4: flocculant dispersion medium block and flocculent aggregate finished water bag of aquatic products is condensed, color particles completely wrapped in it. After the test, this kind of phenomenon is the root cause of the dispersed phase and dispersion medium ph difference between phenomenon caused by chemical reaction. If the dispersion medium basicity is too high, usually condensation polymer dispersion medium, cotton wool, the reticular structure of condensation. Solution: check in advance and adjust the ph of the dispersed phase and dispersion medium, to reduce the ph value, control the generation of acid and alkali of reactants. Water bag colorful coating is different from traditional architectural coatings, such as acrylic coating and styrene acrylic coating. These coatings are single phase and monochrome uniform coating products, product quality is relatively stable, and multicolor paint mixed with heterogeneous and multiphase particles coexist, many problems may lead to the stability of product quality.
