2015-07-10

In the first half of this year, Linyi City's "iron fist pollution control" paid close attention to environmental protection and dared to show its sword to environmental violations. In the process of development, Kemet Aluminum, which adheres to the concept of "enterprise development, environmental protection first", is responding to the national and government environmental protection policies. Under the condition of environmental protection standards, it has continuously carried out technological environmental protection reforms to add bricks and tiles to Linyi's clear water and blue sky. In this process innovation, the most significant effect is the pre-treatment process reform of the spraying workshop. This process innovation is to change the pre-treatment of spraying from chromium to chromium-free passivation. It has been put into operation since May and has achieved initial results, resulting in good environmental and economic benefits. In terms of environmental protection, the chromating agent used in the previous chromating process contains hexavalent chromium, and the hexavalent chromium compound is toxic and carcinogenic, and has great unsafe factors. It must be specially treated by the Kemet sewage treatment workshop. The process is complicated and a lot of manpower and financial resources are wasted. The newly adopted chromium-free passivation does not contain chromium ions. Chromium-free passivation is an advanced technology both at home and abroad. The generated wastewater can be directly treated with oxidized wastewater without special treatment. After treatment, it will not cause any pollution to the ecological environment and save the sewage treatment cost of nearly 60000 yuan per month. In terms of workshop output, chromium-free passivation and compared with the previous chromizing treatment, the process flow time is greatly shortened. The chromium degreasing time is 30 minutes and chromium degreasing time is 3 minutes, while the chromium-free degreasing time is 8 minutes and the passivation time is 40 seconds, which shortens the process flow time. Not only that, the workload of employees is greatly reduced. Compared with the previous chrome framing method, the chrome-free framing method is faster and easier, and the workshop output is increased by nearly 23%. After 2 months, the operation of the pre-treatment process innovation in the spraying workshop has gradually stabilized, and the chromium-free passivation is better than the chromium treatment in terms of ecological environment, cost and output efficiency. Process innovation is an important way to promote the development of enterprises, and it also has a profound impact on the environment. While maintaining healthy and rapid development, Kemet Aluminum has the courage to assume social responsibility, put the concept of environmental protection in the first position of enterprise development, keep pace with the times, and introduce advanced technology in all aspects, laying a solid foundation for the long-term development of enterprises in the future!!
