Abstract: A method for manufacturing an open-cell type copper alloy filter is provided to improve the mechanical characteristic of the filter and make the filter useful in adsorbing heavy metals and purifying silver sewage. Urethane filter foam is cut and pretreated. The pretreated urethane filter foam is inputted into a copper plating solution to be basically plated. The urethane filter foam is electroless-plated and electrolytically plated. The plated product is heated at a temperature of 200-300°C for 1-2 hours. The heated product is treated at a temperature of 500-600°C for 1-2 hours, and treated at a temperature of 600-750°C for 1-3 hours. The pretreating of the urethane filter foam is performed by immersing the cut urethane filter foam into a palladium catalyst, and drying the urethane filter foam, and hating the dried urethane filter foam at a temperature of 100-250°C for 10 minutes to two hours.

Abstract translation: 提供一种开孔型铜合金过滤器的制造方法，以提高过滤器的机械特性，使过滤器可用于吸附重金属和净化银污水。 聚氨酯过滤泡沫被切割并进行预处理。 将预处理的聚氨酯滤泡泡沫体输入到镀铜液中，基本镀敷。 氨基甲酸酯滤泡泡沫是无电镀和电解电镀的。 将镀覆产物在200-300℃的温度下加热1-2小时。 将加热的产物在500-600℃的温度下处理1-2小时，并在600-750℃的温度下处理1-3小时。 氨基甲酸酯滤泡泡沫的预处理是通过将切割的氨基甲酸酯滤泡泡沫浸入钯催化剂中并干燥聚氨酯滤泡进行的，并将干燥的聚氨酯滤泡泡沫在100-250℃下搅拌10分钟至2小时 。
