Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter press technology, and in particular to a filter press for preparing electroless nickel plating. Background Technology
[0002] The plating solution generally uses nickel sulfate, nickel acetate, etc. as the main salts, hypophosphite, sodium borohydride, borane, hydrazine, etc. as reducing agents, and various additives are added. The operation is carried out in an acidic solution at 90℃ or a neutral or alkaline solution near room temperature. Based on the different reducing agents used, it is divided into two main categories: electroless nickel-phosphorus plating and electroless nickel-boron plating. The coating shows superior performance in terms of uniformity, corrosion resistance, hardness, weldability, magnetism, and decorative properties. The filter press is one of the important pieces of equipment for nickel production. In the process of production, some existing filter presses require the addition of reaction materials inside the filter press. During the reaction process, the reaction materials tend to accumulate or adhere to the inner wall of the filter press, which prevents the reaction materials from reacting fully and affects the filtration to a certain extent, thereby reducing the effectiveness of the product.
