types of nails for building

After passivation treatment of galvanized layer, it can generate a layer of bright old and beautiful color passivation film, which can significantly improve its protective performance. There are many kinds of galvanized solution, according to its properties can be divided into cyanide bath and cyanide bath two categories. Cyanide zinc plating solution has good dispersion ability and coverage ability, the coating crystal is smooth and meticulous, simple operation, wide application range, in the production is used for a long time.

Aliases: Gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.

Stainless steel barbed rope service life is, of course, the longer the better. But do you know how to extend the service life of stainless steel barbed rope?

Hexagonal mesh is based on wire mesh prepared by metal wire, wire diameter of 0.3-2.0mm metal wire. Hexagonal mesh is a good choice for breeding cage, he is through hot dip galvanized or PVC coated plastic disposal, the structure is tightly combined with no bump and convex appearance. Keep chickens and ducks, isolate chicken and duck houses, and try to take care of poultry.

In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

For the barbed rope products produced by the barbed rope factory, the number of rotating turns between the two thorns is usually 3-5. What is the internal relationship between this and the length of use?

Cold plating is a physical treatment method, the zinc is simple and uneven, the amount of zinc is also less than in the corrosion and rust prevention and chemical disposal of hot plating; The amount of hot zinc plating is relatively thick, the surface of the disposal is flat on average, and it is not easy to fall off. A layer of alloy composed of zinc and metal has very strong oxidation ability, and there is a layer of pure zinc on the outside of this layer of alloy, which is why hot plating is thicker and stronger than cold plating. Under the condition of high degree of natural recovery, galvanized hook net can play a very good maintenance effect on the environment, it is not afraid of wind and rain, it is the battle machine in the hook net, much stronger than the dip plastic hook net.

Cattle net in the outdoor use of a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know that cattle net if long exposure to harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?

To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the amount of surface-active substances brought in to Z. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

(1) The application method of packaging and binding galvanized shaft wire ordering: ① the pulling position on the goods should be reasonably selected. When used to avoid horizontal movement of goods, the pulling position should be as low as possible; When used to avoid overturning the goods, the pulling position can be appropriately high. ② The use of galvanized iron wire [1] pull reinforcement methods mainly include: figure eight, inverted figure eight, cross, zigzag or reverse zigzag and so on. Various pull methods can be used alone, but also two or more than two kinds of use. The pull should be as symmetrical as possible. (3) When pulling reinforcement, the single or double strands of galvanized iron wire will reciprocate around the goods and vehicles between the two tying nodes, and should be pulled tight galvanized iron wire so that the tightness of each strand is as common as possible, and some of the remaining cross around its own rope rod, and the rest of the tail toward the car.

Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.

Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.
