Read the important properties of container coatings

coating raw materials and equipment network:
china is a large container manufacturing country, about 90% of the world's containers are made in China. Container manufacturing enterprises are mostly concentrated in coastal provinces, mainly in Guangdong, Jiangsu, Zhejiang, Shandong, Shanghai, Tianjin, Liaoning, Fujian and other eastern coastal areas, which provides great convenience for container manufacturing and transportation. Since the 1980s in China's production, container manufacturing industry after more than 30 years of development, has become a very mature industry. According to relevant statistics, China's annual demand for 2.5 million to 3 million TEU (TEU is short for Twenty-feet Equivalent Unit, which is a container volume statistics unit, with a 20-foot container as the standard, a TEU is a 20-foot container) requires about 180,000 to 220,000 tons of paint.​coating refers to the coating used in the inside and outside of the container. Includes workshop pre-coated primer, box paint, outer middle layer of the box, varnish and box-bottom anti-corrosion paint. As containers go through the entire process from land to sea during operation, coatings are required to be highly corrosion resistant under ocean and tropical conditions and can withstand temperature changes of 40-70 degrees Celsius. At the same time to decorate good, unchanged color, non-weathering, wear resistance, resistance to injury, impact resistance, the requirements of trademark adhesives and sealing materials have good adaptability, can withstand the test of harsh conditions, the use of a minimum of 3 years. Container coating is a high-tech, multi-functional coating. Anti-corrosion, thick film, quick-drying, wear resistance, high temperature and humidity, weather resistance and repair resistance are essential performance requirements for container coatings.Anticorrosion:This is the most important performance of container coatings, the life of steel containers is determined by the degree of corrosion protection, requiring steel containers coated with anti-corrosion paint at least 3 to 5 years do not need to be repainted. Container manufacturers from the beginning only focus on box-making prices, and gradually turn to focus on improving the life of the box to reduce the overall cost. They are more concerned with the overall corrosion resistance of the box than ever before.thick film:thickness of the dry film for the first construction is high, which can shorten the construction time and save money.: This islarge-scale container production line, the next process must ensure that the coating is fully dry.wear resistance:containers are often collided during storage and transportation, so container coatings require good wear resistance.high temperature and humidity:Because containers are repeatedly exposed to hot and cold zones, coupled with the large temperature difference between day and night in some areas, this requires container coatings to withstand this environment.weather resistance:strong outdoor sunlight, moisture, sea water can cause paint to fade. The color of the container is important to every company and the owner of the container. Because it symbolizes the company's image in the eyes of users, it is necessary to protect its original color and appearance.repairability:when the paint film is severely scratched and causes peeling rust, it needs to be repaired
