In a high vacuum environment, silver target atoms are bombarded and deposited onto the glass surface by magnetron sputtering technology to form a dense silver reflective layer. After being treated with a protective coating, high-performance silver mirrors are prepared.

1. Physical deposition in a vacuum environment: The entire process takes place in a high vacuum chamber, free from pollution by waste liquid or residue from electroless silver plating. Moreover, there is no oxidation reaction during the silver layer deposition process, and the purity of the film layer is high (silver content ≥99.9%).
2. Continuous automated production: With a multi-chamber series design, the entire process of "pretreatment - coating - post-treatment" can be completed without interrupting the transmission of glass. The daily production capacity of a single production line can reach 3,000 to 5,000 square meters (adjusted according to the size of the glass), making it suitable for large-scale mass production.
3. Precise and controllable film layer parameters: By adjusting the sputtering power, transmission speed and gas flow rate through the PLC control system, the thickness of the silver layer (error ≤±1nm) and reflectance (error ≤±0.5%) can be precisely controlled, and the uniformity of the film thickness is ≤±2% (overall consistency of large-area glass).
4. Composite film layer structure design: Supports a composite structure of "silver layer + auxiliary layer + protective coating", significantly enhancing corrosion resistance and wear resistance, and can adapt to complex usage environments.
5. High target material utilization rate: The adoption of a rotating target structure significantly reduces silver material loss, resulting in better long-term operating costs.

1. The product performance far surpasses traditional processes, meeting the strict requirements of high-end scenarios for reflectivity, corrosion resistance, and surface flatness.
2. It completely resolves the environmental protection pain points of traditional electroless silver plating, eliminating the need to treat large amounts of silver-containing wastewater and meeting modern industrial environmental protection standards.
3. It features a high degree of automation, strong stability in mass production, and a product qualification rate of ≥99%, far exceeding that of traditional processes (≤90%).
4. Silver materials have a high utilization rate. Long-term operation can offset the gap in initial equipment investment, making it economically feasible for large-scale application.
