Mechanical galvanizing at room temperature, through degreasing, rust and wax steel parts into a rotating plating barrel, adding water and impact medium to form a collision, rub the role of the fluid environment, according to the scheduled Zinc Coating Thickness Zinc powder and chemicals are added to form galvanized layers on the steel surface under physical, chemical adsorption and mechanical impact. Technical advantages of mechanical galvanizing Compared with the traditional zinc plating process, the coating of mechanical zinc plating is uniform and bright. The thickness of the coating can be controlled within the range of 5 ~ 110μM by metering and feeding according to the corrosion conditions of the workpiece service environment, and the coating alloying is easy to realize. In addition, the mechanical plating is not like the electroplating need rectification power supply, unlike the hot dipping need heating device, galvanization process at room temperature, plating no hydrogen embrittlement, nor after tempering softening phenomenon. Parts of the same coating thickness, corrosion resistance and plating and hot dip plating; and the production cost is lower than the plating and hot dip coating. Mechanical galvanized operating environment is good, no high temperature, dust, smoke, after plating wastewater by coagulation - coagulation settlement to achieve emission standards. Mechanical zinc plating is widely used in many fields, such as vehicle manufacturing industry, power grid, construction industry, road transportation facilities, construction hardware, hardware and farmhouse, etc. Generally, workpieces less than 300MM in length and less than 1KG in weight are suitable for machinery plating. Most suitable for mechanical plating of the workpiece ring, bolts, nuts, all kinds of gaskets, springs, self-tapping screws, nailing, cement nails, expansion nails, line fittings, pipe fittings and high-strength fasteners. The workpiece can be used for mechanical plating matrix material: non-alloy structural steel, low alloy structural steel, spring steel, cast iron (malleable iron, gray cast iron, ductile iron), powder metallurgy parts. Mechanical galvanized market prospects According to the statistics, the products suitable for mechanical plating in our country are fasteners for electric power, traffic and machinery, plumbing fittings, nailing, cement nails and ring chains (about 2 million T per year). Currently the actual application of mechanical galvanized only about 1 million T per year of output, mainly to the processing and export. With the development of the market, the requirements for metal surface treatment are getting higher and higher. Mechanical galvanizing will replace traditional plating and hot-dip galvanizing in quite a few categories of galvanized parts, and the metal products in industrialized countries gradually shift to high school Stall product development, low-grade hardware products have been transferred to developing countries set up factory production. Compared with countries such as India, South Korea and Vietnam, China has greater market potential, including domestic and processing export markets. It is now gradually developing into a world leader in hardware processing and exporting. In recent years, with the development of mechanical zinc plating technology in our country, the amount of domestic processing commissioned by foreign countries increases year by year and is distributed in Sichuan, Zhejiang, Henan, Hebei and coastal provinces. Shows that mechanical plating in the country has a huge space for development, coupled with foreign machinery and raw materials expensive galvanizing equipment, process complexity, which are for the domestic mechanical galvanizing process and equipment to create a good opportunity for development. With the enhancement of people's awareness of environmental protection and the implementation of environmental laws and regulations, the development of traditional galvanizing technology will be limited. The mechanical galvanizing technology belongs to the "green" surface treatment technology. Due to the good social and economic benefits, the mechanical galvanizing technology Have excellent application prospects.

Mechanical galvanizing is a new technology introduced by industrialized countries in developed countries in recent years. It can realize the clean production process and is a green surface treatment technology. In the process of mechanical zinc plating need a large number of glass beads and the workpiece into a large mixing tank, the use of pneumatic diaphragm pump can effectively improve production efficiency.
