How to solve the color difference of really stone paint and stain resistance? 2019 KeBao paint entire network

True stone lacquer is by far the most popular exterior wall coating. Really stone paint color with natural sand and water-based acrylic emulsion as main raw materials. It's hard to keep different batches of really stone paint color. If, however, can effectively control from the source, production and construction, really stone paint color difference can be solved to a large extent. Next, KeBao building materials will share with you really stone paint colour difference and anti pollution solution. The selection of raw material and control the color sand is the fundamental source of really stone paint colour difference. Natural colour sand are mined from natural colored sand, using artificial crushing equipment, filtered according to the different particle size and the packaging. Due to the different growth period, degree of ore, both inside and outside of sunlight, and other natural factors, in the same area of colored sand ore after crushing processing, the color will be different, some can make a big difference. Different mining area of the same colour colour sand is more difficult to ensure the consistency of color. Mass production color identical really stone paint has a lot of difficulties. At the same time, the feature of natural color to the color of natural colored sand sand downstream of the manufacturer or really stone paint manufacturers also have more stringent requirements. Some large color sand maker when delivery on the downstream production requires the use of mixed mixing equipment, guarantee the consistency of large quantities of color sand color, but the corresponding color sand supply cost will increase, so the color sand and the choice of color sand maker and control as the foundation of control really stone paint colour difference. Production of toner technology level to buy really stone paint colour sand, production and research personnel according to customer requirements and the existing palette color sand type. Unlike traditional coating, really stone paint USES natural colored sand, the irregular shape and uneven coating determines its color cannot through professional spectrophotometer computer color matching equipment calibration, can only rely on experience of artificial toning color engineers and correction. The mixed color engineers have relatively strict requirements, such as familiar with raw materials, sensitive to colour experience, accurately mastering really stone paint formula. Production process control really stone paint production is according to the formula developed by small sample, and then scaling up production, and then modified according to customer requirements. On the production of raw materials feeding method should do it properly, it is a principle with shallow after deep first, first, after more than from the shallow to the deep easy, from deep to shallow. For a small number, color dark colour sand, materials to deduct and complementary methods often can be solved to a large extent color correction repetitions. At the same time, various additives added and adjustment and the process control in the process of production is quite fine. Precise process control and rich production experience, the combination of production and sample color difference is small, high consistency of the necessary conditions for really stone paint. Construction method really stone paint colour difference also is closely related to the construction method and the thickness. For the same really stone paint or same barrels really stone paint, spraying and the color of the scratches will be slightly different. Spraying really stone paint film of simple sense is strong, uniform dispersion, color uniform dispersion. However, scraping effect is flat, and tend to collect with large particle size of grains of sand. Fine sand is easy to float on the surface, fine sand as the main color. Of course, it depends on the specific construction requirements and coating effects. Above is KeBao building materials common really stone paint colour difference and anti pollution solution. The thickness of the different colors of paint or scraping also have differences, so construction method should maintain consistency, and as far as possible do construction. I hope this is helpful to everyone.
