Really stone paint quality problem

True stone lacquer is 100% good products, but why some exterior really stone paint engineering will appear yellow, color difference, flowering, water, pollution and so on quality issues? Kebao from all over the country collected 500 cases of true stone paint problem. 25. 6% is due to the emulsion quality is low, 18. 7% is due to the system is not mature, 23. 3% is due to the unreasonable design, 30. 4% is due to the unreasonable construction. The construction of the high quality really stone paint, system factors must be considered. Must choose high quality latex, product system must be mature, a design must be reasonable, the construction must be specification. 1. Emulsion quality is low, short service life, as film forming matter really stone paint, emulsion plays a decisive role on the performance of the coating, directly related to colour retention, resistance to water, stain resistance, flexibility, weather resistance, service life, etc. For a cheaper price on the market of true stone lacquer is usually styrene acrylic emulsion. Styrene acrylic emulsion linear and flexibility is poor water resistance, resistance to ultraviolet, 2 - Three years will cause yellowing, cracking, black coating quality problems. If the poor quality of styrene acrylic emulsion, after two or three months will appear quality problem. If you have some idea of the development history of really stone paint, the styrene - ten years ago Acrylic really stone paint is already listed. At that time, the sand is not really stone paint. Because the water proofing property is poor, easy craze, demand is very low. In recent years, the market recognition of really stone paint and a big increase in demand, is mainly due to the introduction of the pure acrylic and silicon a crylic-acid system really stone paint. Compared with the early benzene c really stone paint, the true, machinability and coating properties of the product and have improve the quality and improve service life. Therefore, really stone paint name widely circulated. Many customers choose styrene acrylic really stone paint because its price is low, mainly because of the lack of the understanding of really stone paint. It's like, touch screen mobile phone is very popular now, but we buy the touch screen mobile phone still use the backward technology five years ago. Second, the system is not mature, quality risk is very big. System refers to the composition of really stone paint raw materials selection and proportion. Mature system refers to all kinds of high quality raw materials according to certain proportion, can make the product has better workability, flexible, waterproof, weather resistance and service life. Immature system mainly refers to the irrational proportion of various materials, such as cellulose, all kinds of additives, etc. Rather than a single the quality and content of the emulsion. High quality does not mean that the system of mature of the emulsion. Choose the high quality the quality problem of the emulsion must be caused by unreasonable system or formula. Really stone paint system is not mature, such as improper control of cellulose content leads to poor water repellency, additive selection or improper proportion, can lead to a short shelf life, film forming difficulties, water mark, the coating cracking, peeling and other serious quality problem. Mature and stable system mainly through repeated field test of the long-term accumulation. 'Only through product test report cannot be accurately system of the maturity of the conclusions. We must do test walls. And the core of the technical services division of product research and development department job requirement is: practice! Practice! Repeated practice, because practice is main criteria of the maturity of the test system. 'Customers when choosing high-grade really stone paint, must carry on the field survey of manufacturers, fully understand its developing history, successful cases and the degree of specialization. To ensure the quality of the products you buy is guaranteed, so that your money is worth it! 3. Stone curtain wall, glass curtain wall and aluminum, unreasonable design of coatings are easy to pollution, if the design is not reasonable, the outer wall will cause serious pollution. Exterior pollution is mainly caused by unreasonable design, such as the parapet roof design, roof and window sill water drip, drip line design, etc. Scientific and rational design scheme can be fundamentally ensure the beautiful and antifouling coatings, improve the construction quality and the grade. If the design is unreasonable, no matter how good or how expensive materials, they can prevent pollution. Reasonable design, of course, also including the color and frame design. If true stone lacquer is not really stone paint exterior wall coating system composed of grassroots, putty, primer layer, middle layer of coating and paint. To ensure the quality of the finished product, every process must be conducted in accordance with the standards of strict construction acceptance. At the grass-roots level, for example, the water content is 10%, and the ph value ( Ph) 9. High water content can lead to depression, coating with high basicity can lead to excessive alkali coating and frosting. Be bored with child cannot batch of scraping too thick; Primer leakage causes basification; The main material of spraying must ensure that the same material, process, thickness, section and human the same wall, avoid the color difference and dizzy. Any non-conformance will result in the process of quality problems. In addition, the construction experience of each key node is very important, such as how to avoid the stubble in the scaffold construction, how to make the line level, flat, vertical, and how to avoid the Yin and Yang Angle seam, etc. True stone lacquer is semi-finished products. Choosing really stone paint, want to consider not only the enterprise's R&D capacity, consider the technical service ability and the construction experience of enterprises. 'Product three points, seven construction' is the importance of professional construction. As a start painting company, division, attaches great importance to service and construction to provide clients with one-stop high quality finished product solution, which is the core of the concept of division sales. To sum up, really stone paint is very professional, need a lot of precautions. Should pay special attention to the quality of the emulsion and the maturity of the system, the reasonable design, professional construction and other factors. Ignore any one aspect, and ultimately affect the quality of the finished product.
