Introduction to the process of surface treatment for fasteners:

Dalian metal surface treatment, fastener surface treatment is the process of forming a coating layer on the surface of the workpiece through certain methods, with the aim of endowing the surface of the product with a beautiful and corrosion-resistant effect. There are many surface treatment methods and processing techniques for fasteners according to their different product requirements. There are many surface treatment methods, such as painting, electroplating, chemical plating, vacuum coating, and other technologies. As a green and environmentally friendly electroplating technology, alloy catalytic solution utilizes chemical displacement reaction to react with the workpiece itself through infiltration and deposition, forming a new alloy layer with stable performance.

After catalytic treatment, the workpiece still has good rust and corrosion resistance in high temperature and high pressure environments. Currently, this technology is widely used in the field of metal surface treatment. In the surface treatment of fasteners, alloy catalytic fluids have gradually emerged, fully leveraging their advantages. When it comes to locks, lighting fixtures, and decorative hardware electroplating, more than half of them used to be exported, mostly to the United States and some Western European countries. This has led to the rapid development of China's electroplating industry, and Shenzhen electroplating is a new generation of electroplating technology independently developed by Shenzhen. Shenzhen electroplating factories are mainly distributed in Dongguan and Xiamen areas. Shenzhen has a fast understanding and response to the processing needs of the domestic electroplating industry.

 

The electroplating substrates of sanitary ware accessories mainly include stainless steel, copper chrome plating, and aluminum alloy. Each of these three types of products has its own advantages. The main characteristics of stainless steel matrix material are high hardness, not afraid of wear and tear, and not rusting. But the processing style is single, and the engineering degree cannot be very precise. The main feature of copper chrome plating as the substrate is that it has more styles and a relatively moderate price. The mechanical method uses mechanical equipment to grind and remove obvious defects on the surface of the product, such as burrs, oxide scales, welding residues, etc.

Mechanical methods include grinding, polishing, rolling, sandblasting, etc. Environmentally friendly metal pretreatment technology: The two in one degreasing, rust removal and purification liquid technology is highly favored by professionals and consumers for its environmental friendliness and simple operation process through the use of a unique environmentally friendly formula. It avoids the environmental pollution caused by the strong acid and alkali reactions used in traditional oil and rust removal techniques. Common acid washing methods include chemical and electrolytic methods. But the anti-corrosion of the pipeline only uses chemical acid washing. Chemical pickling can achieve a certain level of cleanliness and roughness on the surface of steel pipes, facilitating subsequent anchoring lines.

Dalian metal surface treatment is usually carried out as a post-treatment after shot blasting (sand). Alloy catalytic liquid technology utilizes chemical displacement reactions to form a new type of alloy layer through permeation deposition, which is dense, uniform, and has high glossiness. All raw materials are made from commonly used readily available chemical materials, with over 80% being food additives that can be repeatedly added and recycled, greatly reducing the manufacturer's production costs.
