The pretreatment of painting line
Key words:
The core of cleaner production is "energy saving, consumption reduction, pollution reduction, and efficiency enhancement". It is necessary to adopt advanced technology and materials, select high-end equipment, adopt comprehensive utilization and improve management measures to improve resource utilization efficiency, reduce pollution from the source, and reduce or avoid the generation and discharge of pollutants during the operation of the coating production line. In short, cleaner production does not place the focus on energy conservation and emission reduction at the end, but implements effective management and control throughout the production process. Only continuous technological innovation, improved design, use of clean energy and raw materials, improved management, controlled emissions, and strengthened governance are the means of "clean production". For the German industry 4.0 generation coating production line, the main body of cleaner production lies in planning, design and operation management. This is also the main gap between the domestic brand coating production line and the international advanced level.
Pretreatment System for Painting Line
Before painting/coating, it is necessary to eliminate the oil stains (such as: lubricating oil, emulsion, grease, perspiration, etc.) and dust on the surface of the coated object, so the cleaning is an indispensable process in the pretreatment system before painting/coating. The chemical treatment (conversion film treatment) or mechanical processing (such as shot blasting) for the coated object surface is selected according to the substrate, surface conditions of the coated object or the coating process requirements.
