Design of Zinc Plating Purification Workshop
Introduction
Zinc plating is a widely used post-processing technology in various industries, such as automobile, electromechanical, and aircraft industries. As zinc plating technology plays an important role in the manufacturing industry, it is necessary to design a purification workshop to ensure the purity of the zinc plating. This paper will discuss the design of a zinc plating purification workshop.
Purification Requirements
The zinc plating purification workshop needs to not only ensure the purity of the zinc plating process, but also guarantee the safety of the staff and the quality of the plated products. Besides, the workshop needs to have the ability to prevent pollution sources from entering the workshop and capture particles in order to reduce the amount of contaminants in the plating process.
Design
In the design of the zinc plating purification workshop, the following key considerations must be taken into account:
1. Air pollutions: It is important to control the air pollution within the workshop in order to reduce the risk of metal particles depositing on plated products. The requirement for air pollution control is usually indicated by the numerical value of the mass concentration of various airborne particles. The minimum air quality requirements for the workshop include a particulate concentrate that is no higher than 120 mg/m3 and a fluoride ion concentration that is no higher than 1000 μg/m3.
2. Interior design: There should be two types of areas in the workshop: clean and non-clean. The clean area should be organized in accordance with the requirements of the electroplating production, and must be equipped with air purification and exhaust systems. The non-clean area should be separated from the clean area, with a distance of at least 5 meters.
3. Personnel management: Personnel management should be strictly enforced in the purification workshop. Visitors, personnel from repair and maintenance, or personnel from other workshops should not be allowed to enter, in order to avoid potential pollution sources from entering the workshop. In addition, personnel entering the clean area of the workshop should possess the capability of working in a clean environment? and must comply with the requirements of personal hygiene.
4. Equipment and operations: The purification workshop should use special equipment for the electroplating production, such as purified water systems, anodes, cathodes, and hoists. In order to reduce the pollution of the electroplating solution, the workshop should also employ centralized recycling technology, purification filtration systems, and degassing systems. The staff should be trained in the use of these systems and their operations should be strictly managed.
Conclusion
By properly designing the zinc plating purification workshop, the purity of the plated products and the safety of the staff can be effectively ensured. The key design considerations for the workshop include air pollution control, interior design, personnel management, and equipment and operations. By employing these considerations, a purification workshop that meets the standards of the production line can be designed.
