Due to the limitations of equipment and technology, a large number of processes that are not conducive to environmental protection still exist in the production process of most barrel factories in China. Some are not yet known to people; some are also promoted as advanced technologies; others have set up corresponding environmental protection facilities but have long been out of use. This situation is gradually improving with the improvement of national environmental awareness and technological progress.
1. The development of the barrel-welding process The development of the barrel-welding process is to pre-treat the seams of the barrel plate joints before the seam welding. Its purpose is mainly to eliminate the oxides, oils, etc. on the edges so as to facilitate the joints. weld. At present, the main process in China is edging, that is, grinding wheels are ground with 4 to 8 sets of grinding wheels. The barrel making industry is called edging.
People who have witnessed edging production will be amazed at the fact that the working environment here is really too harsh, there are deafening noises, there is diffuse dust, there is smoke gas smoke... The noise comes from the grinding wheel and the steel plate; It is the grinding of particles under grinding wheel and steel plate; part of the flue gas is the product of the binder in the grinding wheel at high temperature, and part of the result is the result of vaporization of grease on the surface of the steel plate at high temperature. In such a work environment, environmental protection department inspections will often require rectification as soon as possible.
A variety of new welding edge processes have emerged in the country, proving that people still realize the impact of edging on the environment. These processes include edge milling, cleaning, flexible grinding, automatic high-frequency welding. Milling and cleaning processes eliminate noise and dust, but the cleaning process is based on the use of hydrochloric acid and other corrosion on the welding edge of the oxide and oil, often accompanied by toxic and harmful gases, but also the existence of cleaning waste, or right Environmental protection is unfavorable and therefore cannot be promoted. Only automatic high-frequency welding technology due to its advanced welder characteristics, welding edge generally does not require strict treatment can be welded, remove the processing process, thereby reducing the labor intensity, reducing production costs, environmental pollution has also been improved.
2. Development of steel drum coating production technology Steel drum coating production is one of the greatest environmental hazards during steel drum production. The large amount of waste gas, waste water and waste slag produced by the steel barrel coating production mainly comes from the three wastes produced by chemical treatment methods such as degreasing, rust removal, phosphating, and passivation on the surface before coating; organic solvents and paint mists during the coating process. Dispersion, solvent evaporation and other three wastes generated in the drying process.
If the three wastes in the coating process are not properly and properly managed, the harm to the environmental pollution and operators is serious. It is not allowed by the national environmental protection law, and various effective measures are taken to comply with the national environmental protection. The law stipulates that comprehensive governance will be carried out to minimize or fundamentally eliminate the environmental pollution and harm to human health. However, in the past, the treatment of the three wastes in China was a remedial type, which caused the environmental protection work to fall into a vicious cycle of pollution after the first pollution. Therefore, the use of pollution-free or low-pollution production technology is the real way out.
The environmental protection coating technology at home and abroad has developed rapidly, and various coating methods such as high-pressure airless spray coating, electrophoretic spray coating, electrostatic spray coating, and powder coating with advanced coating technology features such as mechanization and automated assembly lines have been widely used. New pattern. In these modern advanced painting methods, the latest painting techniques of automatic program and robot operation for microcomputer program control and closed-circuit television control have been introduced. The new high-protection, high-decoration, low-toxicity, low-pollution paints and thinners complement the semi-mechanized, mechanized, and automated assembly line painting methods such as dip coating, shower coating, roller coating, and photo-curing, radiation-curing coating. It constitutes the development of a new coating system for modern painting production that is efficient, high-quality, low-cost, energy-efficient, reduces environmental pollution, and improves working conditions.
The extensive use of environmental protection facilities has caused the pollution caused by common spraying methods to be gradually reduced. The new coating process is rapidly expanding its application and continuous improvement. The environmental protection equipment is constantly being developed and put into production. At present, China's steel drum coating technology is trying to catch up with the world's advanced level, people's awareness of environmental protection is constantly strengthening, the prospects for environmental protection are beautiful.
