Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.

The strength of the hook mesh should be satisfied: when the vehicle is traveling at 80 kilometers per hour, the hook mesh will not fall into the river when it bumps against the rail at a 15 degree Angle. The shape and color of the hook mesh should be in harmony with the surrounding natural environment. The phenomenon planning of the important Bridges should be done well. When the bridge crosses important traffic lines, such as expressways, urban rail transit, expressways, railway trunk lines, etc., the hook mesh should add the protective mesh on the pavement of the bridge deck.

Open pit coal mine due to poor air quality, a variety of harmful heavy metals are also more, so the corrosion strength of barbed rope products is particularly large, when using galvanized barbed rope must choose hot plating or plastic coated galvanized barbed rope, although the price is slightly higher, but in the long term development is more appropriate. Besides, when the barbed rope is installed near the coal mine, the pile foundation should be fixed to prevent the barbed rope from falling down due to soil erosion, thus losing the protective effect.

Dip plastic six side barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, in particular, is prone to fracture, lose the original protective function.

Bird cage is a kind of pet cage, is the main environment for ornamental birds to carry out activities and habitat, “work to do a good job, must first sharpen its tools” bird equipment is applicable or not, is one of the key to raise ornamental birds. Therefore, only if the appropriate cage and other accessories are prepared first, can the birds be kept healthy and lively, singing freely and suitable for viewing. There are many kinds of cages, depending on their body shape and habits.
