Energy And Resource Requirements Of Color Coated Aluminum Coil

With the development of economic construction, the market demand of Color Coated Aluminum Coil will continue to increase in the future, and the demand for color and variety will be more and more, and the quality of color coated aluminum coil, especially its service life, will be further improved, which will promote the development of color coated aluminum coil towards diversification and high-grade. In addition, with the aggravation of the shortage of energy and resources in the world and the increasingly serious industrial pollution, new requirements are put forward for the energy and resource saving of color coated aluminum coil industry.

In the pretreatment, for the conventional spray pretreatment system, automatic control devices should be adopted to improve efficiency and save drugs by monitoring the treated solution. In order to save energy, low-temperature degreasing methods, low-temperature degreasing agents and low-temperature phosphating methods will be further studied. In order to eliminate public hazards, we will continue to study the pretreatment and sealing system, so that the pretreatment and wastewater treatment of color coated aluminum coil can be completed in a closed system, and on the other hand, we will explore the chromium-free passivation conversion treatment method.

In the aspect of color coating aluminum coil coatings, the research on quick-drying water-soluble coatings will be strengthened to reduce the use of dilution solvents and meet the requirements of high-speed units. At the same time, the coating with high coating quality and high performance was developed to improve the compactness, processability and corrosion resistance of the coating film. High efficiency refers to the low amount of coating, low baking temperature and short baking time on the premise of ensuring quality.

China's aluminum-plastic plate industry has developed rapidly, and color coated aluminum coil production lines have been introduced from different countries. At the same time, on the basis of introduction, we have developed equipment with considerable level by ourselves. In the next step, we should strengthen the cooperation between enterprises and industries, exchange the experience in the import work, study and solve the existing problems, digest and absorb the imported technology as soon as possible, and lift them off together. We should make a systematic and in-depth study of foreign color coated aluminum coil technology, so as to determine our development direction and development fields, organize forces, work together and carry out research experiments, so as to make China's color coated aluminum coil technology catch up with the world level quickly.
