Paint brush has a small impact

　　With the continuous improvement of people's living standards, the use of latex paint to decorate the home has become one of today's fashion. Latex paint shows its infinite charm through different construction tools, making latex paint formula chemists use all kinds of raw materials and technology to make imagination impossible. In addition to the common roll coating and spraying, the application of latex paint is also a common construction method.

　　At present, there are three main types of paint brushes sold in the Chinese building materials market:

　　Natural bristle brushes are usually best suited for the application of solvent-based coatings, especially for the coating and finishing of enamels. Natural bristles are hollow, absorb 50% of their own weight, and swell, soften and bend. Therefore, natural bristle brushes are not suitable for the coating of waterborne coatings.

　　The wool brush is used for brushing water-based paints and is suitable for both wall-coating and wood-based paints. Due to the small manufacturing investment and simple process of the brush industry, a large number of inferior wool brushes are flooding the market.

　　Synthetic material brush It is made of synthetic materials such as nylon or polyester, and is mostly used for brushing water-based paints. In North America, construction workers generally use high-quality synthetic paint brushes.

　　In the long-term cooperation and communication with customers, it is found that there are many phenomena in the manufacture of brushes to cut corners. The strict technical processes, such as boiling, degreasing, bleaching and cleaning, are not in place, resulting in a considerable part of the paint quality. Not only the bristles contain a lot of calcium and magnesium ions, but also contain a lot of acidic substances. The inferior paint brush is stiff and stiff. During the construction process, a large amount of water-soluble high-valent metal ions and hydrogen ions enter the latex paint system, breaking the balance of the latex paint system, causing the main components of the latex paint to flocculate and produce coating particles, resulting in serious Affect the appearance and performance of the film. We usually call this phenomenon a stagnation or sticky brush.
