Foshan environmental passivating agent - aluminum dedicated Foshan environmental passivating agent magnesium and its alloys piece specifically for passivation, is the latest generation of products in today's magnesium alloy surface treatment, in a leading position in the industry. Workpiece treated with superior corrosion resistance, good electrical properties and excellent paint adhesion, completely replace chromate process. Solution does not contain chromium, manganese, zirconium, fluoride and other harmful elements, and in full compliance with the EU ROHS environmental regulations of the country. No emissions, waste water treatment is simple, and after adding only a small amount of flocculation agent can be discharged, the perfect solution to the chronic problem of health hazards and water pollution. The process is simple, easy operation, easy maintenance, low energy consumption, good stability, product qualification rate, very suitable for industrial production lines, has been widely used in the production of products in line with Samsung, ZTE, Huawei, Foxconn and other multinational companies requirements. 1. Environmental characteristics of Foshan passivating agent does not contain chromium, manganese, zirconium, fluoride and other harmful elements, completely environmentally friendly, in line with the EU ROHS requirements. The film was light gray or dark gray, the film is dense, fine uniform, corrosion resistance, resistance to neutral salt spray more than 24 hours, even up to 96 hours after the neutral salt spray resistant coating 500-1000 hours. At room temperature, save energy, suitable for spray and immersion, and the operating range of easy to control. Binding force and excellent coating metal parts, widely applicable process. Wastewater treatment is simple, and after, plus a small amount of a precipitating agent, can be discharged. 2.
