Agricultural Machinery/Engineering Machinery and Container Coating Production Line - Liangshi Engineering Machinery Coating
The report of the 19th National Congress of the Communist Party of China proposed that "in order to build a modern economic system, the focus of economic development must be on the real economy, with improving the quality of the supply system as the main direction of attack, significantly enhancing the quality advantage of China's economy", "building a beautiful China, promoting green development, and strengthening the energy conservation and environmental protection industry". In the context of the new economy New Normal, strengthening the real economy, and building a beautiful China with ecological civilization, the development of China's construction machinery coating industry will inevitably enter the New Normal.
With the increasing international competition, construction machinery manufacturing enterprises are not only paying attention to the internal quality of their products, but also paying more and more attention to the appearance quality of their products. Therefore, higher requirements have been put forward for the appearance quality of construction machinery coating.
Analysis of the current situation of painting technology
(1) Low level of automation. At present, the construction machinery coating line has basically achieved streamlined production, but the spraying of the bottom and top coatings still relies on manual work, resulting in unstable spraying quality.
(2) High energy consumption for painting. In addition to consuming a large amount of electrical energy during the coating process, it also consumes a large amount of gas; Among them, the shot blasting process consumes the most electricity, and the operation of related equipment is entirely driven by electricity; The natural gas consumption in the paint and putty drying process is the highest, and gas drying is required after paint spraying and putty scraping.
(3) Environmental pollution is severe. During the coating production process, a large amount of volatile organic compounds and dust will be generated.

Container coating production line
Containers are specialized tools for international transportation and logistics, with the vast majority being made of steel structures. During use, containers must withstand various harsh environmental conditions on Earth: temperature fluctuations from the equator to the frigid zone of -40~+700C; Wind, rain, and strong ultraviolet radiation; Erosion of high salinity marine atmosphere and seawater impact; Corrosion of gases such as SO2, H2S, CO2, dust, and impurities in urban and industrial atmospheres. At the same time, it also needs to adapt to any mode of transportation by sea or land, such as ships, trains, cars, etc. And it can withstand the friction and collision during non-standard handling operations, so the corrosion of container steel structures is the most severe.
In order to control the corrosion rate of container steel structures and ensure their service value, various measures have been taken in the design, production, and manufacturing processes of containers. For example, in order to improve the corrosion resistance of steel used for containers, high-strength weathering steel such as Corten steel and Baosteel B480 is designed for the top plate and door plate, and stainless steel is even used for refrigerators of international standards. In terms of box structure, anti-corrosion structural design has also been strengthened, such as adopting reasonable structural combinations and shapes to prevent galvanic corrosion and stress corrosion; Avoid gaps and dead corners; Minimize wear and corrosion as much as possible.
The purpose of container coating process is to ensure the value of container use, which is reflected in four aspects:
1. Ensure that the coating on all parts of the container has a high anti-corrosion ability.
2. Ensuring the use value of the inner side of the container:
3. Meet the needs of various owners for the color of the outer side of the container:
4. The sandblasting process of container box welds is an effective measure to prevent stress corrosion of welds:
Characteristics of container coating process:
The container coating process not only includes a series of processes such as pre-treatment of the steel surface before painting (shot blasting, welding seam sandblasting), pre coating, painting, drying, etc., but also includes a series of measures related to equipment technology management. After fifty years of development and improvement, compared to the coating technology for ship steel structures, container coating technology is more standardized and advanced. The purpose of container coating process is to ensure the use value of containers, which is reflected in four aspects. It has the following characteristics:
1. Container coating must adapt to the container manufacturing assembly line. As is well known, container manufacturing is a large-scale and efficient production process.
The shot blasting and rust removal process in container manufacturing, as well as the final layer of asphalt paint, are both coatings that not only run through the entire process of container manufacturing, but also adapt to the entire container manufacturing process. In the painting station of the assembly line, if overtime work or defects occur during weld sandblasting, intermediate coating, and topcoat spraying, it can cause production to slow down or the entire line to be paralyzed.
2. Based on the structural characteristics of containers: Container coating technology must be based on the structural characteristics of containers, which is also the key to ensuring the quality of container manufacturing.
3. Environmental protection is the focus of container coating technology. With the development of science and technology and the strengthening of environmental awareness, the International Container Standardization Committee attaches great importance to the development and application of green and environmentally friendly coatings for containers. Container factories have also strengthened their efforts to treat the three wastes in coating.
With the development of science and technology and the strengthening of environmental awareness, the International Container Standardization Committee attaches great importance to the development and application of green and environmentally friendly coatings for containers, and various container factories have also strengthened their efforts to treat the three wastes in coating. Improving environmental friendliness is the development direction of container coating technology
4. Container painting is advanced and normative: compared with the painting process of ships and steel structures, the container painting process is progressiveness and normative.
