Solving the problem of color difference really stone paint quality to eliminate from the manufacturers

Off color is the most common problem really stone paint spraying. There are two reasons. One is in the process of construction, really stone paint coating thin and thick. And really stone paint quality problems. Under normal circumstances, it is easier to control the mass production of really stone paint color difference. Fujian KeBaoZhen QiChang production of natural stone really stone paint more master really stone paint production control technology, to prevent the problem really stone paint colour into the market. Really stone paint need to mass production, so really stone paint single cylinder production capacity should be increased. The single cylinder production capacity, the greater the off color is more easy to control. The same number really stone paint production batch is smaller, the smaller the color difference. Really stone paint in order to control the production process, it is suggested that the water first, emulsion and various additives made really stone paint pulp, adjust the viscosity of the slurry, then stir in really stone paint kettle, adding formula of various sand. Sand principle is: first add the fine sand powder, and then with thick sand; If the dose is small, first join; If the dose is very big, will add later. Add white sand, and then wholesale really stone paint, and then add the color sand. In addition, the color sand should have certain allowance, can not add, because the different between mass production and small-scale experiment, especially the fine powder is used for blending, allowance should be bigger. Really stone paint emulsion in content is too low, too fine or sand sand contains more fine powder, even paste used for color mixing, film forming additive, film-forming temperature is too low, paint film emulsion base material with the color sand between there will be a large number of pores, the pore of the refractive index is lower than the base material and sand the refractive index of air ( The refractive index of air is 1, the refractive index of a base material is about 1. 5, packing of refractive index is about 1. 5) The differences, the refractive index increases. Enhanced light scattering, similar to the high PVC latex paint, have a certain degree of dry hiding power; At the same time, the pore size also has a great influence on the scattering efficiency. It was found that the best scattering film pore diameter of 0. 7 microns. Really stone paint used in the color sand is fine, color sand between the pore diameter is smaller, the closer the air the best scattering pore diameter, the stronger the scattering effect. Above is fujian KeBaoZhen stone paint manufacturers no chromatism quality really stone paint production process, from the production details truly improve the quality of the really stone paint. Really stone paint color difference directly affects the appearance of the exterior walls. High quality really stone paint products will attract more attention, fujian KeBaoZhen stone paint is a high quality product.
