Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed rope has beautiful, economical and practical, good resistance effect, convenient construction and other excellent characteristics.
The duration of the protective effect of galvanized layer on large roll galvanized wire is closely related to the coating thickness. Generally speaking, in the dry main gas and indoor use, the thickness of galvanized layer only 6-12μm, and in the environment is more severe conditions, galvanized layer thickness needs 20μm “to be up to 50μm”. Therefore, the influence of environment should be considered when choosing the thickness of galvanized layer.
When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well. Galvanized wire, also known as hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.
The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
3, wear gloves, take about a bottle of disinfectant cap, pour into the basin, dilute with water according to the reference ratio. Dip a small brush into the diluted disinfectant solution and scrub the cage.The cooling circulation system uses spray to cool the drawing die, and takes away a lot of heat generated by the drawing machine in high speed drawing in time to ensure the quality of the wire. Control drawing process parameters: drawing speed 10 ~ 12m/s; Winding tension 8 ~ 10N; Measuring length 30km; The mass fraction of lubricant is 3.5 ~ 4.5%; pH value of lubricant 7 ~ 8; Lubricant temperature 30 ~ 40℃.
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.
The chromium-plated layer has good thermal property. When the temperature is heated below 500℃, its luster and hardness are not changed obviously. When the temperature is higher than 500℃, the initial oxidation and discoloration occur, and the hardness decreases when the temperature is higher than 700℃. The friction coefficient of chrome coating is small, especially the dry friction coefficient, which is low among all metals. So the chrome coating has good wear.The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
The national standard 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 is better, I’m afraid is 10×10×0.6.
In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.
The utility of hexagonal net in the playground is very superficial, in the stadium built in each city, are less than the shadow of the hexagonal net. In the stadium around the installation of hexagonal net, not only can improve the stadium of the group image, but also convenient urban residents to implement a row of activities.
