First, the basic concept of aluminum paste Aluminum pigments, also known as aluminum powder pigments, are metallic aluminum powders with scaly particle structure and bright metallic luster and other pigment properties. They are mainly used in the production of paints, printing inks, plastic materials and other products, and are already in automobiles, Consumer electronics, home appliances, construction materials, plastic materials, and textiles are widely used. Aluminum paste is an indispensable metal pigment. Its main components are snow flakes of aluminum particles and petroleum solvents. The feature is that the surface of the aluminum sheet is smooth and smooth, the particle size distribution is concentrated, the shape is regular, and it has excellent light reflection ability and metallic luster. Mainly used for automotive coatings, metal industrial coatings, marine coatings, heat-resistant coatings, roof coatings. Aluminum paste is divided into floating and non-floating two major categories. In the grinding process, the replacement of one fatty acid with another will give the aluminum pigment a completely different character and appearance. Because the appearance of each type of aluminum sheet is different from other types, the technical parameters that affect the product's application formulation and end use will also vary depending on the desired effect. Floating Aluminum Silver Paste: In floating aluminum pigments, aluminum flakes are oriented to form an opaque silver film near the surface of the paint film. This opaque property is the main factor that makes the floating aluminum pigment become an important functional raw material. . Floating aluminum pigments are mainly used for roof coating, maintenance, anti-corrosion coating, reflective coating, imitation plating coating, and commercial coating that require high protection. Non-floating aluminum paste has excellent coloring and has a strong hiding power. It is widely used in industrial coatings, auto parts coatings and decorative coatings . The non-floating pigments are evenly distributed in the entire paint film, and the formed coating film has a different appearance from the floating aluminum pigments . Because it can be mixed with a variety of pigments for a variety of systems, it has a unique effect on industrial coatings. Any pigments or dyes used in combination with non-leafing aluminum pigments must be transparent in order to achieve a realistic metallic effect. Non-leafing aluminum pigments have a variety of acid-resistant grades, which can reduce the influence of industrial smog, acid rain, and other adverse environments on the coated parts. In the past two or three years, China's aluminum-silver paste products have also started to use the fine spherical aluminum powder as the raw material direction. There has been a major technological breakthrough in China, but its performance indicators, coating effects and other aspects have not been achieved. The level of similar foreign products. Second, the development of our aluminum pigment industry China's aluminum paste production industry started from the early 1990s, and its production history is relatively short compared with foreign companies. Companies that started earlier are Zhangqiu Metal Pigment Co., Ltd. After the development of domestic aluminum paste in recent years, the quality of domestic aluminum paste has achieved good results on ordinary fine silver, but there are still some gaps between products with high flash point and imported products. Zhangqiu Metal Pigment Co., Ltd. is the most complete product line among aluminum silver paste manufacturers in China. Its products cover both floating and non-floating types, ranging from ordinary aluminum silver paste series, imitation aluminum plating silver paste series, to plastic special aluminum. Pigments, electroplated silver and aluminum silver paste series. The majority of its products are low-end products. Recently, high-end products have increased. The product is very good in metal resistance to chemical and mechanical properties, especially high temperature resistance, especially for metal paints . With the continuous development of China's economy and the continuous increase in market demand, China's paint industry has made great progress in recent years . Last year, the output of the paint industry slowed down, the growth rate of output value declined, and the price of products dropped significantly. However, the increase in corporate profits increased; international and domestic companies promoted environmental protection and energy conservation, and industry enterprises actively cooperated; at the same time as industrial restructuring, the company changed the paint industry. The development approach accelerates the structural and technological upgrading of the paint industry and accelerates the realization of the traditional open process, solvent-based, low-grade, general functional products, to closed, integrated processes, environment-friendly, high-end, and high functionality. Product change. 2013 paint industry demand, China will steadily grow. At present, the domestic aluminum silver paste market demand is 15,000 tons, of which foreign imports are about 4,000 tons . However, we must clearly understand that there are still many factors constraining the sustainable development of the industry in China's paint industry. Compared with previous years, the economic growth rate of the paint industry has slowed down in 2012, and the industry still faces a series of problems in the development process . Such as lagging industrial restructuring, weak technological innovation capabilities, insufficient market demand, increased operating costs, severe product homogeneity, and intensified industrial vicious competition. However, the development of China's paint industry is still in an important period of opportunity. Although many unfavorable factors still existed in 2013, the external environment will gradually improve. The country vigorously promotes the construction of new urbanization and gradually implements the expansion of domestic demand. It can be said that the domestic demand market will continue to provide the paint industry with momentum for achieving stable development. It is expected that the industry will produce and sell this year. The growth rate is expected to increase steadily, the pace of structural adjustment will further accelerate, and the economic operation of the industry will continue to maintain steady growth. Third, the control of aluminum silver paste size The particle size distribution of the aluminum silver paste depends on the production equipment and production process parameters used to manufacture the powder coating. The type and the system are different, and the relative control of the particle size distribution is also different. In general, the smaller the particle size of the powder, the better the leveling property when the coating is cured, and the smoother and smoother the appearance of the coating film, but the powder is too thin and the electrification property is reduced, and the coating application efficiency is reduced. At the same time, too fine powder also increases the difficulty of powder production. The silver particle size detection and control are of great importance to production and application companies. The spraying of white goods and other fields requires high powder particle size, and the wet laser particle size analyzer is the first choice. It is necessary for manufacturers exporting powder coatings to configure a laser particle size analyzer. Zhangqiu Metallic Pigment is currently the largest aluminum silver paste manufacturer in China and is now a professional aluminum pigment production base in China. The high-quality floating and non-leafing aluminum pigments produced by R&D have been recognized by the coatings, inks, paints, coatings, automotive paints, and leather spray industries . The products produced by Jinan Micron Particle Instruments Co., Ltd. serve the various aluminum and silver paste companies in the country and have brought accurate service and testing to customers in the aluminum paste industry.
