Embodiment 1

[0042] Example 1: electro-gold on the surface of jewelry

[0043] When the electroplating layer on the surface of jewelry is a gold-plated layer, the specific process of electro-gold treatment:

[0044] (i) Surface polishing to remove sand holes and file marks on the surface of the workpiece.

[0045] Surface polishing is carried out according to the conventional steps in this field, which can include frying and polishing, polishing and polishing the surface of the workpiece with supporting tools, so that the rough surface of the workpiece becomes smooth and shiny, so as to carry out timely and effective repair; wax removal, repair, Make up for the defects, defects, damage, etc. of the workpiece; glue (oil); sandblasting; oil (nail polish); glue removal, and finally electrolytic polishing.

[0046] (ii) Ultrasonic cleaning; ultrasonic degreasing uses the mechanical force of ultrasonic oscillation to generate tens of thousands of small bubbles in the degreasing solution. , T...

Embodiment 2

[0056] Embodiment 2: the surface coating processing of jewelry after gold-plated treatment

[0057] The specific treatment process includes: spraying nano-coating and optical coating.

[0058] Step (1): Spray nano-coating, the specific process is as follows:

[0059] Need to use special jigs, select the appropriate jigs according to the jewelry that needs to be processed, first install the jigs on the production line, and then wear dust-free gloves to install the products to the production line along with the line. Note that the operator must wear medical gloves when installing the products. , to prevent fingerprints from directly touching the product with hands. Production lines conventionally used in the field for spraying nano-coatings are applicable as long as they can meet the process requirements.

[0060] (1-1) Electrostatic dust removal: Adjust the electrostatic air gun, aim at jewelry products, and remove dust from the products at a distance of 10 cm.

[0061] El...

Embodiment 3

[0081] Embodiment 3: the surface coating processing of jewelry after electro-gold treatment

[0082] The specific details and precautions of the experimental process are the same as in Example 2.

[0083] Step (1): Spray nano-coating

[0084] Select the appropriate jig according to the jewelry that needs to be processed, first install the jig on the production line, and then wear dust-free gloves to install the product to the production line along with the line. Note that the operator must wear medical gloves when installing the product to prevent direct contact with hands Product has fingerprints.

[0085] (1-1) Electrostatic dust removal: Adjust the electrostatic air gun, aim at jewelry products, and remove dust from the products at a distance of 15 cm.

[0086] (1-2) Plasma treatment: The distance between the plasma torch head and the jewelry product is 3mm; the treatment is carried out until the water drop angle is ≤10°.

[0087] (1-3) Spraying: Use multiple spray gun...

Abstract

The invention relates to the technical field of jewelry processing, in particular to a fadeless plating processing technology. The fadeless plating processing technology includes the following steps that (1) a nanometer coating is spayed, specifically, electrostatic dust collection is conducted on jewelry treated through surface electroplating, then the nanometer coating is spayed, and after spraying is completed, the nanometer coating is baked and cured; and (2) optical filming is carried out, specifically, the jewelry sprayed with the nanometer coating is cleaned and then subjected to optical filming through silicon dioxide and AF materials. According to the processing technology, after the nanometer coating and an optical filming layer are added to the jewelry, gold plating of the jewelry has excellent abrasion resistance, high water and oil repellency, and durable anti-microbial performance, anti-pollution performance, and anti-fingerprint capacity; and the surface of the jewelry keeps bright and clean for a long term, and the surface layer is intact, free of abrasion and fadeless.

Description

technical field [0001] The invention belongs to the technical field of jewelry processing, and in particular relates to a non-fading coating processing technology. Background technique [0002] Jewelry surface treatment technology is mainly divided into two categories: mechanical treatment and electrochemical treatment. Mechanical treatment mainly uses relevant mechanical tools to polish, polish, sandblast, etc. jewelry, in order to achieve the required process requirements and effects. Electrochemical treatment is the use of electrochemical methods to corrode, passivate and protect the metal surface, especially for complex-style jewelry and the back of jewelry flower heads that are not easy to be polished and polished. Electrochemical treatment method has its unique advantages. [0003] At present, there are many electrochemical treatment processes, mainly including electroplating (electrogold), electroless plating, and chemical conversion coating technology. In the jewe...
