As we all know, the purpose of painting the fence fence factory is to make the product better anti-corrosion effect. So what should we pay attention to in the product painting?

River isolation network because of different regions are not close to the same, some places called river guardrail network, reservoir isolation network and called river bridge guardrail and so on, but they refer to the same kind of product, we all know that the river isolation network fence itself is a kind of obstacle, to prevent people and cars falling into the river, if installed river isolation network will not appear such a problem, Its setting is conditional, generally in the river fence set guardrail and more people and vehicles installed guardrail maintenance, the relative risk of discrimination. As long as the correct planning, guardrail to play its own function and advantages. Today, I will introduce to you the style of the river isolation network.

In general, when exporting and exporting, the blade thorn rope will be packaged and sold, so that the volume occupied in the container is relatively small, which can be easily placed and will not occupy much place.

The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.

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. Also known as: twist flower net, stone cage net, gabion net, flood control network.

It is best to use special columns to fix the barbed rope installation, because the standard column is not only beautiful shape and better protection effect.

In our daily life, what we can bend with our hands is basically galvanized iron wire, not steel wire. It has a high zinc content, which ensures excellent toughness and resilience, as well as ultra-high corrosion resistance, which can be maintained in outdoor environments for decades. There are many practical galvanized iron wire, such as strong reliability, galvanized layer and iron together, forming a special metallurgical structure, in the use and transportation process, can ensure that it will not be mechanical damage.

Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.

Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh boxes, the inside of the filler are selected stones, these stones are not easy to wear, and between the stones and stones will retain some gaps, so it is very good to meet the drainage requirements.

In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.

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.

Hexagonal net structure can be used for slope support, excavation, rock face net mine support form, slope vegetation (green color), railway road isolation block, it can be made into a cage, cushion, used for rivers, flood dam and seawall erosion protection and storage reservoir, river closed cage. Driving and guiding rivers, river flood disaster is a major water and river erosion of destruction, resulting in flooding, resulting in a great deal of loss of property by the amount of soil and water dissipation. Because of this, in dealing with these problems, the application of the habitat grid structure becomes a solution plan, which has the potential to protect the bank forever.

Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it is also necessary to conduct reasonable post-processing to avoid affecting its use effect. Of course, when the black iron wire is galvanized, it is also necessary to ensure the thickness of the galvanized layer, so that it can also reduce the possibility of rust. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.

This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.

Although galvanized iron wire has the protection of galvanized layer, it does not say that it will not rust at all, but delays the time of rust. In general, cold galvanized iron wire can be kept for 1-2 years without rust, hot galvanized iron wire can be used for 8-10 years without rust. If properly maintained, the use time will be longer. So how to prevent galvanized iron wire rust?
