- 3. The structure of the dog cage should be reasonable
- The production and processing process of the blade thorn rope is complicated, which requires the cooperation of all departments, and the production cycle is relatively long. Whether galvanized rope or stainless steel rope, because of the relatively simple structure, the degree of mechanization in the production process is relatively high, so it is also a relatively big difference in price.
The custom application of hexagonal guardrail network plays a very important role in the channel slope protection work. According to the performance of the network, it can firmly grasp the soil so that it will not be lost, so the customized slope protection effect of hexagonal guardrail network is very significant, but also because of this advantage, it is widely used in such as channel protection, river bank protection, landslide protection. The custom structure of hexagonal guardrail is tightly combined, the appearance is not concave and convex, and it has satisfactory anti-corrosion, anti-oxygen and other capabilities. Construction without a lot of manpower and material resources, can be in the field of actual operation.
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
- National standards on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter size, on the plaster layer to use is mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, light selection diameter is not much significance, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which one is better? 10×10×0.6, I’m afraid.
Galvanized barbed wire (barbed wire) is made of galvanized barbed wire twisted on the main wire, so as to play a protective and isolation role. Among them twist weave way is divided into single twist weave and double twist weave. Construction methods include direct installation and spiral insertion.
- 3, galvanized silk mesh binder transport, storage and use should be in accordance with the relevant provisions to adopt safety, fire prevention methods, so as to be more safe use.
1, galvanized silk mesh molding sheet must be packed with flat hard materials, to avoid improper packaging and cause eternal deformation. It is important that each package and roll of raw material be marked with product name, standard, quantity, trademark, lot number, manufacturer, date of production, packing symbol, inspector code and inspection certificate.
Post time: 07-07-22- Non-proportional extension strength: It is mainly for hard steel without yield point. It is defined as the stress where the residual elongation of the standard distance part reaches 0.2% of the length of the original standard distance.
Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
- The mixture of rare earth and aluminum enhances the fluidity of zinc liquid, makes the coating more uniform, and also reduces the zinc consumption. Hot dip galvanized wire has better protection performance than cold galvanized wire, which makes it good application in chemical experimental equipment. Hot dip wire coating thicker, so that it has good corrosion resistance, can be in the outdoor sun and rain and other harsh environment can be maintained for decades, so hot dip galvanized wire is widely used in construction, traffic guardrail and other outdoor facilities.
The anticorrosion of these raw materials are very different, the use of life is not the same. Cattle fence cold galvanized, also known as electroplating, galvanized little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) zinc content in 60 grams to 400 grams, the use of life is about 20-60 years, corrosion resistance is general.
- The principle of hot dip galvanizing is simply that clean iron parts are immersed in a zinc bath through Flux wetting, so that the steel reacts with molten zinc to produce an alloyed skin film.
- ① The diameter of galvanized iron wire for pulling should not be less than 4mm, and the diameter of galvanized iron wire for binding should not be less than 2.6mm.
- Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
- Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. If it is a hexagonal metal galvanized layer of metal wire, the wire diameter is 0.3mm to 2.0mm metal wire, if it is a PVC coated metal wire braided hexagonal net, the use of 0.8mm to 2.6mm PVC(metal) wire. Twisted into a hexagonal shape, the outer frame edge of the line can be made into a unilateral, bilateral, movable silk.
Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve.
- Reverse twisting of the barbed rope: first wrap the barbed wire around the main wire (that is, a single piece of iron wire) and then add an iron wire and twist together to form a double strand of barbed rope.
First, spray to prolong the service life of stainless steel barbed rope
- If the solder joint is too deep, it is not good, although the welding is more solid, but the bearing capacity of the solder joint is greatly reduced, once the pressure exceeds the load range, it will fracture at the solder joint, so it is more dangerous to use. Large galvanized wire production process of low carbon steel wire cleaning cleaning agent, should have no effect on the binding force of the coating, no corrosion of low carbon steel wire. Production process, acid activation acid activation liquid, should be able to remove the surface of low carbon steel wire corrosion products, oxide film, no corrosion to the matrix.
Wet air in rain and snow climate, steel mesh sheet exposed, easy to rust, to avoid affecting the use of steel mesh, it is necessary to carry out simple rust prevention treatment, of course, slight rust float will not affect the use of steel mesh. Common network site storage, rainy days, heavy snow, rainy days and rainy days, how to better save the steel mesh, this is a lot of friends need to consider.
Galvanized wire according to the production technology can be divided into: hot galvanized wire, electroplating wire hot plating: 8# — 36# (3.8mm,0.19mm) electroplating: 8# — 38# (3.8mm-0.15mm)
As we all know, the mechanism of resistance to atmospheric corrosion of zinc includes mechanical protection and electrochemical protection. Under the condition of atmospheric corrosion, there are ZnO, Zn(OH)2 and basic zinc carbonate protective film on the surface of zinc layer, which to a certain extent slows the corrosion of zinc. When this protective film (also known as white rust) is damaged, a new film will be formed.
- First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.
(1) In the painting construction should pay attention to ventilation, moisture-proof, fire prevention. The working environment and painting tools should be kept clean, the pressure of the air pump should be controlled within 0.63MPa, and the safety valve should be checked for failure.
