In the production and recycling process of circuit boards, efficient separation and recovery of resin powder are key links to improve resource utilization, ensure environmental compliance, and ensure production continuity. The water selection circuit board equipment developed by Jiangxi Mingxin has deeply integrated the filter press into the process system, achieving precise and efficient processing of resin powder filtration, providing a reliable solution for circuit board processing enterprises.1、 Application scenarios and core requirementsThe core of the water separation process for circuit boards is to achieve the separation of metal and non-metal components through water flow separation. Resin powder, as the main non-metal product, has the characteristics of fine particles, low density, and easy suspension. If it cannot be effectively filtered and separated, it will not only cause water pollution, but also lead to waste of resin resources. The pressure filter installed in the Jiangxi Mingxin water selection circuit board equipment is designed specifically for this pain point. It is mainly used for the terminal filtration treatment of wastewater containing resin powder after water selection, as well as the centralized recycling and reuse of resin powder, meeting the strict requirements of enterprises for solid-liquid separation efficiency, filter cake moisture content, and environmental emissions.2、 The core advantages of pressurized filters1. High filtration efficiency, suitable for continuous productionThe pressure filter press adopts the principle of pressurized filtration, applying stable pressure through a closed filter chamber, allowing the sewage containing resin powder to quickly penetrate the filter medium. Compared with traditional vacuum filtration equipment, the filtration speed is increased by more than 30%. The equipment can be linked and controlled with the Jiangxi Mingxin water selection circuit board equipment, automatically adjusting the filtration parameters according to the processing capacity of the water selection process, ensuring that resin powder does not accumulate and sewage does not remain during the continuous processing of the circuit board, effectively improving the operational efficiency of the entire production line.2. Good separation effect and high resin recovery valueIn response to the small particle size of resin powder, the equipment is equipped with high-precision filter cloth, with a filtration accuracy of over 500 mesh, which can effectively intercept more than 99% of resin powder particles in sewage. After filtration, the suspended solids content in clean water is less than 10mg/L, which can be directly reused in water selection processes or discharged in compliance with standards. At the same time, the moisture content of the resin filter cake formed by pressure filtration is as low as 15% or less. The filter cake structure is compact and easy to collect, reducing the cost of subsequent drying treatment. The recovered resin powder has high purity and can be directly used as recycled raw materials in related industries, improving resource recovery efficiency.3. Stable and reliable operation with low maintenance costsThe main body of the equipment is made of corrosion-resistant stainless steel material, which can withstand the erosion of residual chemical agents in sewage and extend the service life of the equipment. The filter cloth adopts an automatic cleaning and unloading device, which can complete backwashing and filter cake peeling at regular intervals, reducing manual intervention and lowering the workload of operation and maintenance. In addition, the equipment control system integrates multiple monitoring modules such as pressure, flow, and liquid level. When abnormalities occur, it can automatically alarm and stop for protection, avoiding the expansion of faults and ensuring safe and stable production operation.3、 Equipment adaptation and environmental valueThe pressure filter in Jiangxi Mingxin's water selection circuit board equipment can be customized according to the actual production scale of the enterprise (daily processing of circuit boards of 50-500 tons) to adapt to water selection production lines with different production capacities. In terms of environmental protection, efficient interception and recycling of resin powder not only reduces solid waste emissions, but also reduces the difficulty of sewage treatment, helping enterprises meet relevant regulatory requirements such as the "Electronic Waste Treatment Pollution Control Standards" and achieve the goal of "reduction, resource utilization, and harmless treatment".In summary, Jiangxi Mingxin has integrated filter presses into the water selection circuit board equipment system, solving the problem of resin powder filtration through process optimization and equipment integration. This not only improves production efficiency, but also achieves resource recycling and environmental protection standards, providing an economical and environmentally friendly solution for the circuit board processing and recycling industry.
