Water sand bag of colorful coating preparation and matters needing attention

Water is water bag after bag sand upgrade the product, it combines the advantages of water bag and really stone paint. Although these three are marble, but water pack sand effect more natural, more vivid, especially for litchi surface stone, water bag of sand can completely reach the level of true and false. The following is a Shared water bag of sand preparation process of colorful coating assembly briefly. 01 adhesive solution preparation according to the formula according to take protect powder, general protection adhesive solution concentration of 5% 25%. ( KeBaoZhen stone coating protection glue is easy to disperse, good stability and good compatibility with other materials in the system. Excellent water resistance, good compatibility with water-based resin, suitable for multicolor coating containing sand mold. ) Stir with a certain amount of water, fully transparent, stirring until solution. Set aside. 02 continuous phase preparation according to the formula of adding water, latex, thickener, and other additives, mixing stir well. Set aside. 03 primer preparation according to the formula of adding water, additives, the material such as titanium dioxide, kaolin, scattered 5 - at a high speed For 10 minutes. Adding cellulose, maintain medium speed and high speed stirring. When material viscosity increased, slowly add emulsion, additives, etc. 15 - continue to stir For 30 minutes. Slowly add preparation good protective glue solution, maintain medium-speed and high-speed mixing state, about 15 minutes, stirring until smooth. 04 toner particles 1 and primer. Will be 20 - 200 mesh quartz sand according to certain proportion to join in the primer, adjust color according to the color of the template. 2. The good color particles according to certain proportion to join protect glue solution. 3. Granulation for later use. 05 finished paint production according to the requirement of the formula ratio, mixing in a specific equipment, the continuous phase and color particle mixing. This is the finished paint. Water bag of sand and water bag color dot grain principle and influence factors are basically the same. The difference between the two is that of water emulsion paint is a kind of pure water, sand and water bag is a kind of sand wall coatings. Therefore, the water sand has higher technical requirements and strong ability of coating color point. The particle size is less than 15 um it can not only cover the paste, can also cover size for 20 - 200 mesh ( The biggest size is 420 um) Sand, which requires the water pack sand color dot has higher toughness and stability. At present, there are many on the market of water and sediment package system. Choosing water pack sand system, should be preferred to package the coarse sand and fine sand with high water sand system. 1. Good system model more extensive stone varieties, can meet the requirements of a variety of texture; 2. Sand production color is more stable, not easy separation, color is not easily broken, especially when in mass production and mix. 3. The cost would be more economical.
