Coating industry can not be ignored "four kinds of coatings
2018-01-11
As the paint industry is often used in architectural coatings, are generally used for exterior wall decoration and outdoor decoration, but in our daily life there are many small kinds of paint is often ignored, but in our life but plays a big role, the following small series with you to discuss which kinds of paint in our daily play an important role.
container paint
In the early development of the container manufacturing industry in the 1980 s, the container coatings used in China were imported coatings designated by the owners. Such as Denmark's Hep (Hempel) company, Germany's Freilacke company, the Netherlands's Sigma company and so on. With the development of China's container manufacturing industry, more foreign paint factories have entered China's container industry through the relationship with container owners. Since the early 1990 s, Haihong-Hempel, Shanghai-Kansai, Shanghai-Chugoku, Shanghai-IP, Kunshan-K. C.C and other Sino-foreign joint venture container coating companies have been established one after another, using the container coating approval certificate of foreign investment companies to take over the national container coating business.
Since 1993, several research institutes and coating manufacturers have begun to develop container coatings in China. For example, the products of the Ship Technology Research Institute of China Shipbuilding Corporation were also sent to the Kon-standt Laboratory in the United States for testing. The container coating development project of Shanghai Kailin Paint Factory was included in the original key research projects of the Ministry of Chemical Industry and Shanghai's Eighth Five-Year Plan, but it was not implemented for various reasons.
high temperature resistant coating
With the rapid development of the world industry, the production process continues to innovate, the performance requirements of industrial materials continue to improve, and the innovation of industrial materials better demand. Among them, the chemical industry coatings industry to meet this new challenge, we must grasp the pulse of the development of the world's industrial coatings industry, keen analysis of new market trends, the development of high-tech industrial new industrial coatings, timely follow and promote the rapid development of China's industry. It can be said that it is some special needs in the industrial environment to promote the research and development of high temperature resistant coatings. Under the premise of modern scientific and technological progress, the high temperature resistant industrial coatings that have been developed have its uniqueness, which can give full play to the functions of many coating products and equipment, and become an indispensable new variety in the coating industry. Generally speaking, high temperature resistant coatings can be divided into two parts: civil high temperature resistant coatings and industrial high temperature resistant coatings. According to the general definition, high temperature resistant coatings not only cover many fields such as automobile, construction, metallurgy, manufacturing, medicine, transportation, ship and container coatings, aerospace, traffic identification system coatings, but also include various daily production products used by people, such as gas stoves, water heaters, electric heaters, etc, it can be said that high temperature resistant coatings and people's daily life, industrial production interest phase.
The technology of high temperature resistant coatings needs material technology, chemical technology, information technology, biological engineering technology, energy technology, nanotechnology, environmental protection technology, space technology, computer technology, marine engineering technology and other modern high-tech and its industry as a whole. High temperature resistant coatings not only play an important role in promoting and supporting the development of high-tech, but also play an important role in promoting the transformation and upgrading of related traditional industries in China and realizing leapfrog development. From the current development situation, energy-saving environmental protection and low pollution of water-based high temperature resistant coatings are generally believed to eventually replace solvent-based high temperature resistant coatings. According to relevant data, the current industrial high-temperature coatings have accounted for about 20% of the world's industrial high-temperature coatings, and it is estimated that this proportion will rise to 30% by 2010. In the developed regions of Europe, this proportion has reached 30%, and industrial high temperature coatings have broad market prospects.
nano thermal insulation coating
Ms. Wang's family lives on the top floor in Beijing. In summer, the room is hot and stuffy. The temperature can reach 35 ℃. The indoor air pressure is low, which makes people breathless. In order to cool the room, the air conditioner needs 24-hour cooling. The electricity bill in summer is more than 4 times higher than that in winter. This year, Ms. Wang painted nano sunscreen and heat insulation paint on the roof of the building. No matter how hot it is outside, the room is always kept in a constant temperature and cool state, and there is basically no need to turn on the air conditioner for refrigeration.
A logistics staff office in Beijing Economic Development Zone, in May this year, when the weather was not hot, the indoor cumulative temperature could reach 33 ℃ after being exposed to the sun, and the staff could not work normally. In June, after the logistics company painted nano sunscreen and heat insulation coatings on the walls and roofs of the office, although the outdoor temperature was much higher, the indoor temperature was much lower than that in May. After the paint was painted, the indoor temperature dropped by more than 6 ℃, the starting time of the air conditioner was less than 25% of the previous time, and the power saving rate of the air conditioner was as high as more than 75%.
steel structure coating
With the improvement of anti-corrosion requirements for steel structure and environmental protection restrictions, anti-corrosion coatings for steel structure coatings are further developed in the direction of low solvent and high solid components, resulting in coatings becoming more and more difficult to spray with high viscosity and thick slurry. The traditional construction methods are manual brushing and air spraying. Manual brushing is not only inefficient, but also inevitably leaves brush marks, and its paint effect is difficult to satisfy. Air spraying is bound to add a large amount of diluent due to the inability to atomize high-viscosity anticorrosive coatings, resulting in rising costs and environmental pollution, and excessive dilution leads to a decrease in the film-forming ability of the paint and affects the life of the paint coating. But the use of high-pressure airless spraying construction technology, this problem will be solved.
High-pressure airless spraying, its working principle is to pressurize the paint to several hundred kg/cm2 through high-pressure airless spraying equipment, atomize the paint into fine particles through the nozzle, and spray it directly onto the surface of the coated object.
