development of architectural coatings for interior and exterior wall decoration in the United States

[China paint information] the development of architectural coatings abroad has gone through a long historical journey. Especially in developed countries, architectural coatings are used most for interior and exterior wall decoration. At present, the total output of coatings in the world is about 28million tons, of which architectural coatings account for 40% to 50%, about 11-14 million tons. In industrial developed countries, architectural coatings are the largest category of coatings in consumption, accounting for about 50% of the total output of coatings. The annual output of architectural coatings in the United States has remained at about 2.7 million tons for nearly a decade, accounting for 52% of the total output of coatings, of which water emulsion coatings account for 75%; Solvent based coatings account for 25%. The proportion of architectural coatings in other developed countries in the total amount of coatings is: Italy 57%, Germany 55%, France 55%, Japan 40%. In the United States, 45% of the external walls of buildings are decorated with paint. Japan is also a major paint producer in the world, with the output ranking third in the world. The annual output of architectural coatings is about 1million tons, accounting for about 40% of the total output of coatings. The per capita consumption of architectural coatings in the United States and other industrialized countries is more than 10kg, while China is less than 1kg, which is a big gap, but compared with the per capita industrial output value, it is reasonable

now take the United States as an example for a brief introduction:

the United States has a developed economy and many building decoration materials, but the interior walls rarely use expensive decoration materials, mostly architectural coatings. In terms of exterior wall decoration, architectural coatings account for more than 80%. For example, the exterior walls of buildings in Los Angeles are almost completely decorated with architectural coatings, and only a few high-rise buildings are decorated with aluminum-plastic plates. It is difficult to find face brick decorative materials. In New York, we can also see face brick decorative materials, but they are still mainly architectural coatings, especially for new buildings. The colorful exterior wall paint makes the city very beautiful

interior wall decoration is mainly paint and wall wallpaper (cloth). It is rare to see walls decorated with high-grade wood in a large area, while wallpaper (cloth) is only used on other interior walls outside some bedrooms. No matter how high the decoration grade is, almost all of them use paint. It's just that some handicrafts or paintings are used for decoration, and there is no feeling of low grade at all

it is also common to use cement base coating. Many well-known buildings use this kind of coating on the ground, but some carpets are paved in some parts. The floor coating is widely used on the ground of industrial plants, which has the effect of wear resistance, skid resistance and decoration

the total investment of some public projects is planned to reach 3 billion yuan. The walkways of public places, tourist places and other places adopt colored cement floor coatings, such as Disneyland

lithium manganate and lithium iron phosphate of enterprises are mainly used in the field of large-scale energy storage and power batteries; Due to the improvement of the safety technology of lithium battery manufacturing and the requirements of lithium battery for energy density, collectivization and specialization

in the United States, most enterprises form group companies, even originally large enterprises, but in order to cooperate and develop, they also join large groups

RPM group is a group company mainly engaged in the production of coatings. The company is formed by many enterprises. Although some subordinate enterprises have low level and single products, the group is large in scale and high in technology. When participating in the competition, the whole group appears, which greatly improves the competitiveness of products. There is a clear division of labor within the group, so the subordinate companies are more professional. Zinger company is a member of the group. Founded in 1849, it is an old paint production company. It should be said that it has strong paint development and production capacity. However, the company mainly produces more than 70 varieties of primers, while only a few varieties of topcoats. Because of its excellent primer quality, many major coating companies in the United States use Zinsser primer to match it. The company's primers are divided into two categories, namely, water-based and oil-based, and each category is divided into two categories: suitable for general base and suitable for porous base. It is further divided into different varieties according to different grass-roots levels. Each primer has its own scope of use, such as new concrete, old concrete, new wood, old wood, treated walls, untreated walls, etc

pay attention to scientific research and product quality

the competition in the composite material market of the U.S. government scientific research aircraft and aerospace industry is very intense, and there are few testing centers in the industry. Developing new products and ensuring good quality are the needs of enterprises, and every enterprise attaches great importance to it

Rust-olce μ M is a member of RPM group, and its scientific research instruments and equipment are very advanced. The company is small, with a total of 185 people, including 30 scientific researchers, who are mainly engaged in developing new products and improving product quality according to the tasks assigned by the company. The company pays great attention to good quality. Control the whole process of raw material selection, formula design, process flow, packaging, etc

raw materials and finished products are classified with bar codes, production is fully automated, and assembly line operation is adopted. There are only a dozen operators in the whole cart room. In order to timely understand the quality control of each link, there is a channel to the quality control center, from raw material storage tanks, reaction kettles, graphene dispersion tanks in the research on the endurance mileage of new energy vehicles to paint mixing tanks. The center samples and analyzes at any time to ensure product quality

advanced production technology

foreign architectural coating manufacturers have their own core technologies and leading products. In the personnel composition, scientific research and development personnel account for 30-40% of the total number of enterprises; Marketing and management personnel account for 30-40%; Front line production personnel account for only about 20%. From resin synthesis to coating preparation, it is developing towards large-scale and automation. If the reaction device reaches 40~60kl; In addition to high-grade decorative coatings, most of the coating dispersion devices for construction use 10~20kl star dispersion grinding devices, which greatly improves the labor production efficiency. Due to the computer system used in the control, the process control and various parameters are stable, with good repeatability and reliable quality. The closed batching system, automatic conveying and metering system, automatic color matching system, automatic packaging system and so on are used in the coating preparation, and the production environment and production efficiency are satisfactory. In addition, most enterprises have passed ISO9000 series quality management certification, which provides a reliable guarantee for product quality both in hardware and software
