Problems solved by technology

Due to the large volume and weight of the drying box frame, and the relatively small surface area, the loading ratio in the plating tank is too small, only 0.5-1.5dm 2 / L, it is difficult to guarantee the quality of the coating by using the existing electroless nickel-phosphorus alloy plating process

Abstract

The invention relates to an application of chemical plating nickel phosphorus alloy to a triallyl cyanurate (TAC) film production line and belongs to the technical field of ordinary carbon steel surface treatment. Workpieces subjected to pre-treatment are plated in chemical plating nickel phosphorus alloy liquid with certain composition and concentration to obtain nickel phosphorus alloy plating layers with high smoothness, uniform compactness, high hardness and good corrosion resistance, the phosphorus content of the plating layer is 9 to 12 weight percent, the hardness value is 600 to 800HV, and the time of not generating rust spots in the salt spray corrosion tests reaches 300 to 500 hours. Active metals are bound on the workpieces, and the potential of the workpieces is reduced, so the deposition speed reaches 12 to 15mum / h. The application is particularly applicable to workpieces with a small loading ratio in a plating bath.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of common carbon steel, and particularly relates to the application of chemical nickel-phosphorus alloy plating on a TAC film production line. Background technique [0002] TAC film is an important raw material for the manufacture of polarizers, the core components of liquid crystal displays, and also has important applications in the field of solar photovoltaic panel packaging. The production environment of TAC film contains methylene chloride, which will produce corrosive substances when encountering water vapor in the drying process. This requires workpieces such as drying oven racks used in the drying process to have corrosion resistance. At present, most of these workpieces are made of stainless steel, etc. It is made of alloy steel, but stainless steel is expensive and difficult to cast, and ordinary carbon steel cannot resist chloride ion stress corrosion. To solve this problem, ...
