Problems solved by technology

In production, as the concentration of the electroless tin plating solution changes, the immersion time is affected by the concentration of the electroless tin plating solution. If the concentration is high, the immersion time required is short, and if the concentration is low, the immersion time required is long. The required immersion time Difficult to control accurately
In actual production, the zipper color difference often occurs (the zipper is white or yellowish), which causes the zipper to be reworked and affects the production efficiency.

Embodiment 1

[0018] The H65 brass zipper was selected for the experiment, and it was processed according to the following steps:

[0019] (a) Ultrasonic degreasing of the zipper: The parameters of the ultrasonic degreasing liquid are: sodium hydroxide 0.5% (mass fraction, the same below), sodium carbonate 3%, sodium phosphate 0.8%, OP emulsifier 0.8%, temperature 60 ℃. For example, GDS-1036 ultrasonic degreasing machine is used, the ultrasonic power is 2160W, the ultrasonic frequency is 28KHZ, and the size of the inner tank is 650mm (length) × 500mm (width) × 430mm (height). Clean the zipper with clean water after ultrasonic degreasing for 10 minutes.

[0020] (b) Polish the zipper: first immerse the zipper in the polishing solution for 4 minutes to form a layer of purple-red film on the surface of the zipper. The composition of the polishing solution is: 30wt% hydrogen peroxide 600ml / L, 98wt% sulfuric acid 6ml / L, and the balance is water; then place the zipper in a 98wt% sulfuric acid ...

Abstract

The invention relates to a manufacturing method of light-golden zippers, and belongs to the field of zippers. The manufacturing method of the light-golden zippers includes the steps that after the zippers are processed in an oil-removing mode, the zippers are processed in a chemical polishing mode, after the chemical polishing, silver is displaced chemically to form a silver layer, then the zippers are dried in a water-throwing mode, the zippers are baked for 20-30 minutes at the temperature of 120-130 DEG C, and finally, varnish coating and stoving curing are performed. Traditionally, by relying on manual experience, the light-golden zippers are formed in a chemical tinning mode, but according to the manufacturing method, yellowing processing is performed after the sliver is displaced chemically, through accurate control of the baking temperature and the baking time, color difference of the zippers is reduced, reworking is reduced, and the zippers are steadily produced.

Description

technical field [0001] The invention relates to the field of zippers, in particular to a method for making a light gold zipper. Background technique [0002] At present, the zippers on the market are mainly divided into three categories: nylon zippers, plastic steel zippers, and metal zippers. Common metal zippers are generally made of brass substrates, which are mainly oxidized and colored to enrich the color of the zipper and improve the corrosion resistance of the zipper. Among them, the light gold zipper is generally made in this way: after the brass zipper is degreased, the zipper is chemically polished. After polishing, the surface of the zipper is smooth and golden yellow; then the zipper is dipped in chemical tin plating solution. A thin layer of silver-white tin layer is formed on the zipper, and the zipper is quickly taken out for cleaning, so that the golden-yellow zipper is silver-white and becomes light gold. Using this method requires good manual operation ex...
