Really stone paint of the common problems and solutions

Really stone paint from the selection of raw materials, formula, production to the construction of a complete system. Quality control of highly specialized and systematic. Any inappropriate links or minor details will directly damage the decorative effect of the finished product. KeBao edge xiao today to talk to you really stone paint common problems and solving methods: 1. White water, poor water resistance on the market are some really stone paint in flushing after soaking rain will clear white, after the clear weather will recover. This is really stone paint direct expression of poor water resistance. Reason 1: the emulsion with low quality low and low emulsion often add excess surfactant in order to increase the stability of the emulsion. These surfactants can greatly reduce the resistance to water of emulsion itself. Reason 2: the low dosage of emulsion quality latex prices are relatively high. In order to save costs, manufacturers only added a small amount of the emulsion, makes the paint film after drying loose and imperfect. Paint film is bibulous rate is relatively large, bond strength reduced accordingly. If it rains for a long time, the rain will infiltrate the paint film, make the film become white. Reason 3: excessive thickening agent some manufacturers often add a lot of carboxymethyl cellulose, hydroxyethyl cellulose, etc. When making really stone paint is used as thickener. These substances are water-soluble or hydrophilicity. To stay with the coating film, coating, reduce the water resistance of the coating. Solution: 1. Choose high quality latex to choose excellent resistance to water of high polymer acrylic polymer as film forming material, improve the true stone water resistance from the source. 2. Increasing proportion of emulsion latex proportion, adding amount of really stone paint emulsion a large number of contrast test, to ensure that really stone paint after construction can obtain dense complete paint film, prevent water invasion. 3. Adjust the proportion of hydrophilic substances in order to ensure product stability and machinability, it is necessary to add the hydrophilic substances, such as cellulose. The key is to find a precise balance, this requires a lot of repeated trials to study the reasonable proportion hydrophilic material such as cellulose. Can not only ensure the effect of the products, but also to minimize the effect of water resistance. 2. Splash is a serious waste of some really stone paint, can fall in the process of spraying sand splatter everywhere, even in serious cases will waste about one-third. Reason 1: the natural gravel gradation is not really stone paint, gravel particles cannot adopt uniform particle size distribution of particles of different size particles have to mix and match. If the uniform particles or unreasonable particles match, spray flying. Reason 2: the construction of the improper operation may be spray gun diameter is too large, improper selection pressure spray gun, other factors may also cause a splash. Reason 3: improper coating consistency unsuitable coating consistency adjustment will cause in the process of spraying sand and splash, and serious waste of material. Solution: 1. Adjust the gravel gradation excessive use of small diameter natural gravel leads to film surface texture is low; Excessive use of large diameter gravel easy to cause a splash and sand. Only when the mixture in proportion according to certain series, it is uniform. 2. Adjust the operation if it is the cause of the spray gun, need to adjust the diameter and pressure of spray gun. 3. Adjust the consistency of coating. If coating consistency is reason, need to adjust the viscosity. 3: really stone paint flowering reason 1: the influence of ph value is greater than 9 at the grass-roots level will lead to bloom phenomenon. Reason 2: the construction of uneven thickness to blossom. In addition, really stone paint too little and the dosage of paint film is too thin will cause the frosting. Reason 3: in the production process of really stone paint, cellulose high proportion is the direct reason for flowering. Solution: 1. Strict control at the grass-roots level of ph, using alkali resistant seal primer for back cover, prevent precipitation alkaline substances. 2. Strictly carry out the normal dosage, don't cut corners. Really stone paint theory of normal dosage of 4. 5 ~ 5. 3 5 kg/square metre. C major reasons: qualified really stone paint film is very hard, cannot fit with nails. Paint film is too soft, improper selection is mainly due to the emulsion or low levels, leading to insufficient coating sealing film forming process. Solution: to really stone paint manufacturing, should not choose the same emulsion and latex paint manufacturing emulsion used, and should choose higher adhesion, film forming temperature lower composite solution. Above is edge xiao summary for everyone really stone paint common problems and solutions. Really stone paint selection is very important, we must choose a good brand like KeBao.
