Embodiment 1

[0028] A method for electroless silver-tungsten alloy plating on a rhinestone pavilion, comprising the steps of:

[0029] Step 1. Scrub the rhinestones that wrap the crown and expose the pavilion after absorbing the film through a scrubbing machine. During the scrubbing process, circulate and spray the scrubbing solution on the brush through a corrosion-resistant pump; the composition of the scrubbing solution includes in parts by weight: 1 part of alumina powder, 1 part of calcium carbonate powder, 2 parts of gelatin, 2 parts of glycerin, 1 part of sodium lauryl sulfate, 93 parts of water.

[0030] Step 2. Put the water drill treated in step 1 into an ultrasonic wave equipped with a degreasing liquid and clean it for 15 minutes, and then rinse it with clear water; the composition of the degreasing liquid includes by weight: 6 parts of sodium phosphate, 6 parts of sodium carbonate, 1 part of sodium silicate, 87 parts of water.

[0031] Step 3. Put the rhinestones treated in s...

Abstract

The invention discloses a method for chemical plating of a silver-tungsten alloy to a crystal pavilion part. The method comprises the following steps of scrubbing, oil removing, glue removing, neutralizing, roughening, surface active agent treatment, sensitization and chemical plating. The pretreatment technology is improved, meanwhile, the proper roughening and sensitization technology and the proper silver plating liquid formula are adopted, accordingly, the attaching force of a silver plating layer of a product obtained after silver plating is improved, and the phenomenon of yellowing, blacking and whitening of the silver plating layer is avoided. According to the method, the crystal pretreatment technology is further improved, the innovated chemically-plated silver-tungsten plated liquid and the matched reducing liquid formula are utilized, it is guaranteed that blacking, yellowing, whitening and other appearance defects cannot happen to the crystal plating layer, and the appearance quality, attaching force, alkali resistance, acid resistance, high-temperature resisting performance, electric plating resisting performance, salt spray resistance and the like of the crystal plating layer can meet the requirement of the Crystal industry standard.

Description

technical field [0001] The invention belongs to the technical field of rhinestone electroless plating, in particular, the invention relates to a method for electroless silver-tungsten alloy plating on a rhinestone pavilion. Background technique [0002] Rhinestone (crystal, rhinestone) is also known as crystal diamond, rhinestone. The main component is crystal glass, which is a kind of jewelry accessory obtained by cutting crystal glass into diamond facets. This material is more economical and has a diamond-like eye-catching visual effect. Therefore, it is very popular, and rhinestones are generally used in mid-range jewelry design. Classification of rhinestones: According to the color, it can be divided into: white diamonds, colored diamonds (such as pink, red, blue, etc.), colored diamonds (also called AB diamonds), and colored AB diamonds (such as red AB, blue AB, etc.). At present, the manufacturing process of rhinestones is mainly divided into two steps. The first par...
