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.

Each coil of steel wire shall consist of one wire. The surface of the rod shall not have cracks, folds, scars, ears, layers or inclusions. However, indentation, pits, bumps, scratches and pockmarks are allowed, and the depth or height shall not be 0.2mm. There should be no corrosion and oxidation skin on the surface of the steel wire, and oxidation color is allowed by heat treatment. The surface of the wire is allowed to have scratches not exceeding half of the allowable deviation range of the diameter, and local defects not exceeding the allowable deviation of the appropriate diameter.

Now hexagonal net is used in a large number of Bridges, piers and bridge buttress inclined plane protection, bridge buttress inclined plane there are many kinds, people according to the inclination of the inclined plane to choose the right hexagonal net, when the inclined plane gentle, people generally use gabion slope protection system, and in the case of steep slope, people will use gabion mesh gravity protection wall.

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.

With the improvement of people’s living standards, now many families are raising some small pets, these small pets need a stable nest, pet cage has become a more important choice of people, each pet habits and living habits will choose to adapt to the cage. Pet cage has many types, and selective is bigger, pet cages are generally made of wire, with better coarse, then at the bottom with a wheel base, such a simple pet basket was made, in the wheel at the bottom of the mount is for the convenience of the mobile, a pet cages should also adapt to the location of the production in addition to a door, It is convenient for feeding pets.

Now many hardware manufacturers produce iron wire, and iron wire is very easy to rust, if you need to use in outdoor or humid places, generally customers will require the use of galvanized iron wire equipment to give the wire a layer of zinc, the thickness can be determined according to user requirements. Galvanized iron wire equipment is specially used for the plating of iron. Generally speaking, the stability of zinc is much higher than that of iron, and it will not rust in the daily water vapor or damp place.

Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, it will not rust like the corrosion layer on the surface of hot dip galvanized barbed rope, because the internal material of stainless steel barbed rope is the same as the material on the surface. The most obvious difference in a short time is the cross section of this piece, hot dip galvanized barbed wire because of surface anticorrosion treatment, so there will be rust in the cross section of this piece, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.

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.

Hardness is a commonly used property index in mechanical properties of metal materials. The iron wire factory introduces a fast and economical test method for hardness testing. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.

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.
