On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.

The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.

Now many industrial products will be made of stainless steel wire rope material. In order to identify the fake and inferior stainless steel, certain measures and methods can be taken. But many customers do not know what way to identify, listed the following identification methods for you.

If it is not packaged, then a car of blade thorn rope can not be loaded with many pieces, and it is also relatively occupied and easy to lose in the transportation process. The number of the packed blade thorn rope is 50 bundles, and the volume is reduced after hydraulic compression so that it is more convenient to load and unload, and the forklift can easily load and unload. Under normal circumstances, when exporting, the blade thorn rope will be packaged and sold, so that the volume occupied in the container is relatively small, which can be easily placed and will not occupy much place.

This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.

Hexagonal guardrail network custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break, lose the original protection function.

Galvanized hexagonal mesh features: easy to use; Save transportation costs. It can be reduced into small rolls, and involved in moisture-proof paper packaging, occupying little space. Coating thickness uniformity, corrosion resistance is stronger; Simple construction, no special technology; Strong resistance to natural damage and corrosion resistance and the ability to resist adverse climate impact; Can withstand a wide range of deformation and still not collapse. Play the role of fixed heat preservation and insulation.

3. Acid activation acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts, without excessive corrosion on the matrix.

The invention technology is used to put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and plays an important measure to stabilize the PH value within a numerical range, and also facilitate the filter filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.

In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.

Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Hot dip galvanizing is dipped in zinc liquid melted by heating. It has fast production speed, thick but uneven coating. The market thickness is 45g and can reach more than 300g. The color is dark, the zinc metal is consumed, and the matrix metal is formed into the entry layer, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can adhere to decades.

With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.
