The use of spring in a specific environment, there will be some special requirements for steel wire, such as: the use of spring in corrosive media, must have good corrosion resistance function. Precision instruments used in the spring, should have long-term stability and sensitivity, temperature coefficient to be low, high quality elements, after effect to be small, elastic modulus to be stable.
However, because the bath contains highly toxic cyanide, the gas escaping from the electroplating process will do great harm to the health of workers, and its waste water must be strictly treated before discharge. Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be used in some outdoor guardrails or fences, especially on handicrafts, which are also of great use. Galvanized iron wire is not easy to rust and oxidation on the surface.
Barbed wire was used as a barrier to livestock theft, for one thing, because the surface was covered with sharp spikes that made it very difficult to penetrate through the barbed wire. On the other hand, it is because livestock generally have the habit of running into each other, which makes livestock dare not run into each other with the barbed rope, thus saving the user’s use cost.
Galvanized diamond net to reduce the impact of the project on the environment, protect the slope protection area of the land, maintain the rock can be fully strong, slope protection hook net through artificial planting grass planting, the implementation of green function. Suitable for any complex terrain, at the same time, does not destroy the original landform, the product is mesh distribution, visual interference, convenient for artificial afforestation, conducive to the environment, engineering and environment integration system flexibility.
Hook fence is made of hook fence for the net surface of the protective net, barrier grid. Material PVC wire, stainless steel wire, good low carbon steel wire, galvanized wire, iron wire hook mesh is made of hook mesh machine for various materials of wire hook knitting, can be divided into two kinds of folding, screwing lock.
Large roll galvanized wire as a common industrial supplies in daily life, many people will use, but many of them are not standard operation. Cold galvanized wire is one of the many categories of iron wire, widely used, cold galvanized wire is a kind of galvanized iron wire products made of high quality low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes.
2. Use a large pickpocket to stir the zinc ash before the steel wire enters the zinc liquid; Use a small outlet for the galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. After the removal of zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption. This is one of the measures to reduce zinc consumption, but it is also a real problem, which has not been solved for many years.
After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron in the dry air is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements, its production cost is lower, use and scale is wider, better protection function, so it is an important material for iron and steel parts in a strict working environment.
Wire-wall welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold. The coating on the surface of the weld core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
Cold galvanizing is also called electric galvanizing. It is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into the solution of zinc salt, and connect the anode of the electrolytic equipment, place zinc plate on the opposite side of the pipe, and connect the positive pole of the electrolytic equipment to the power supply. A layer of zinc is deposited on the pipe fitting by directional movement of an electric current from the positive pole to the negative pole. Cold plated pipe fitting is processed before galvanizing.
