Post time: 03-02-23 - Copper sulfate point test is a simple way to quickly distinguish ordinary carbon steel and all types of stainless steel wire rope. The concentration of copper sulfate solution used is 5%-10%. Before the point test, the experimental area should be thoroughly removed from the oil or other impurities, and a small area should be polished by grinding machine or soft grinding cloth, and then the test liquid drops to the grinding place. Ordinary carbon steel or iron in a few seconds will form a layer of outer metal copper, and the surface of stainless steel does not produce copper precipitation or display copper color.

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.

Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction.

4. Keep the rinse water clean after pickling the steel wire
- In addition, hot-dip galvanized wire also needs to pay attention to maintenance and maintenance during use. Although it has good corrosion resistance, the zinc-iron alloy protective layer of hot-dip galvanized wire will gradually wear out after a long time of use. Therefore, regular inspection and maintenance of the surface of hot-dip galvanized wire, such as recoating or anti-corrosion treatment, helps to extend its service life.

Factors affecting the corrosion resistance of galvanized wire: The corrosion resistance of galvanized wire is affected by many factors, mainly including the following aspects.
- Selection of cage size tips
- The common type of barbed rope is double-strand barbed rope, and the models are 2.0*2.0mm, 2.25*2.25mm, 2.7*2.25mm, and all of them are galvanized barbed rope (plastic coated barbed rope is rarely used). The barbed distance (that is, the distance between winding wires) is generally 14 cm. Here’s what these models mean:

Post time: 11-10-22 - The electrolytic deposition of large roll galvanized wire zinc-chin layer is basically the following two kinds of electrolyte: zinc is mainly in the form of zinc cation hydration in the solution; Zinc is mainly present in solution as complex anion. Acid electrolyte belongs to one class, complex cyanide and zincate electrolyte, and nickel sulfate electrolyte constitute the second class. Cyanide electrolyte and acid electrolyte are of great significance.

The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.

Are you familiar with galvanized silk mesh? Do you know what to pay attention to in the process of use?

Now when most people buy barbed rope, they choose blade barbed rope. Why is this? From the material, the blade barbed wire process is made of hot-dip galvanized steel plate or stainless steel sheet to press the sharp blade sheet, and the high-tension galvanized steel wire or the blade barbed wire is made of stainless steel wire as the core wire. Because the shape of the gill net is not easy to contact, so it can reach an excellent protective barrier effect.

The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.

Use in daily life does not need to carry out maintenance and maintenance, save a lot of time, but also save maintenance and maintenance costs. The annealed wire has good stability and corrosion resistance, which greatly prolongs its service life. There are many kinds, which can be selected according to different uses. The device for making anneal wire is simple, which improves the utilization rate of the device. The material properties of annealed wire can meet different processing requirements.

- Because of its light weight, strength is relatively large has gradually begun to replace the original column. At the same time, due to the relatively uniform specifications, the barbed rope installation is also more beautiful. The direct spacing of the barbed rope is relatively fixed, which can effectively prevent crossing. At the same time, the mesh at the bottom is relatively dense, while the mesh at the top is relatively loose, which can save resources.
- 4, according to the wire diameter thickness to adjust zinc dipping time
- The small homogeneous particles with large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles will cause explosion. Coating with activated carbon to remove surfactant, or filtering to make the foam less stable, are effective measures. Other measures should also be taken to reduce the amount of surfactant brought in to Z. The speed of electroplating can be significantly reduced by the addition of organic matter. Although the chemical formulation is conducive to high deposition rate, but the organic matter with the coating thickness can not meet the requirements, so activated carbon can be used to treat the tank liquid.
- Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation; Power plant tied pipe, boiler warm; Anti-freezing, residential protection, landscaping protection; Raising chickens and ducks, isolating chicken and duck houses, to protect poultry; To protect and support seawalls, hillsides, roads and Bridges and other waterworks.

It’s not clear why friends would want to use building nets for floor heating. What is its advantage in the floor heating project, the role of steel wire mesh is convenient for construction. Building mesh can better fix the pipe, conducive to the construction of the floor, improve efficiency. Anti-cracking function. The building network can improve the bearing capacity of the foundation of the insulation board, the thicker the diameter of the building steel wire, the greater the bearing capacity, effectively prevent the appearance of cracks and cracks of steel wire mesh can improve the thermal shrinkage and shrinkage of cement, strengthen the tensile strength of cement, improve the quality of the heating project.

Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
