Dip is one of the anticorrosion methods of galvanized diamond net. For hook mesh immersion is one of the methods of anti-corrosion, now the domestic more mature method is: powder immersion method, it originated from the fluidized bed method, the so-called fluidized bed is used in the Winkler gas furnace on the oil contact decomposition, and then developed the solid-gas two-phase contact process, gradually used in metal coating. So sometimes it is still called “fluidized bed coating method”, the actual process is to add the powder coating to the bottom of the porous, breathable container, the blower from the bottom into the treated compressed air, so that the powder coating turned to the “fluidization state”. It becomes a fine, evenly distributed powder.

Hexagonal guardrail network custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break, lose the original protection function.

Before wall plastering, the wall column is connected to the gap construction wire mesh, which can play a certain strengthening and heat preservation effect. The mesh is hung on the interface surface of different grassroots, and the length of each side should meet the requirements of 100mm, so as to prevent shrinkage and cracking caused by different grassroots. Mesh wire diameter can also determine the effect and efficiency of construction, mesh fine laid up convenient soft, high construction efficiency; Of national standard can assure quality, but laid respect is inferior to fine construction fast.

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.

The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire sales. There is also the difference in processing technology also leads to the difference in the price of the blade barbed rope. The traditional barbed rope is mechanically twisted, with relatively small labor consumption and high production efficiency. But the blade barbed rope is after the second mechanical processing in the artificial processing operations to appear. Therefore, there is a big gap between labor force and production efficiency. These factors lead to the price of the blade barbed rope is more expensive main factors.

Because the large roll galvanized wire alloy element in ore iron, can make copper through the thickness, hardness, impact force, strength, library rate, elongation, so alloy iron in the exercise of good iron, is an important auxiliary element. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.

Packaging is also very important, cut wire to do a good job in the bundle with plastic film tightly packed, and then in the regular box, to fill the whole box is very full and sealed, it is best not to have a half box of conditions, if there is a half box to fill with foam and other things, so that in the transit cut wire will not receive a little damage.

Galvanized iron wire has tolerance and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.

Smelting technology is good, advanced equipment, advanced process of large stainless steel plant whether in the control of alloy elements, impurities removal, billet cooling temperature control can be guaranteed, so the product quality is stable and reliable, good internal quality, not easy to rust. On the contrary, some small steel equipment is backward, backward process, smelting process, impurities can not be removed, the production of products will inevitably rust.

One is to do a good job of galvanized wire packaging, to avoid bumping, to ensure the integrity of the zinc layer;

We have to carefully choose a good cage for the parrot, so that it has a comfortable home.

One: according to the different color of the spray blade, its price is higher than that of the ordinary blade, but the cost performance of the spray blade is much higher.

There are many blade specifications, first of all there are three types: spiral type, straight line, spiral cross type. Different units, the strength of the protection of different rope models. The blade barbed wire is mainly made of low carbon steel wire and aluminum magnesium alloy wire by spraying and welding. The blade material of the blade barbed wire is attached to the core wire made of stainless steel wire with professional mechanical strength, so the blade barbed wire has the advantages of good strength and aging resistance.

Compared with other galvanizing processes, the cleaning requirements for low carbon steel wire before galvanizing are low. However, under the current trend of increasing the quality level of galvanized layer, some pollutants brought into the plating tank are obviously harmful. Because cleaning galvanized coating wastes a lot of time and reduces the production, it is very important to properly clean and effectively rinse the substrate before electroplating.

The electrolytic deposition of large roll galvanized wire zinc-chin layer is basically the following two kinds of electrolyte: zinc is mainly in the form of zinc cation hydration in the solution; Zinc is mainly present in solution as complex anion. Acid electrolyte belongs to one class, complex cyanide and zincate electrolyte, and nickel sulfate electrolyte constitute the second class. Cyanide electrolyte and acid electrolyte are of great significance.

The external environment has great influence on the preservation of galvanized wire mesh. In the rainy season, it is necessary to pay attention to the air humidity of the workshop, warehouse and other departments. It is recommended to use a humidifier. Usually, the moisture absorption of book paper is larger than that of powder paper, and the pH value is higher. Generally speaking, in the normal environment of storage wire, storage time of two years is not corroded wire phenomenon. However, it should be noted that in the process of handling the iron wire, it should be handled gently to avoid the position of the coiling coil, which will cause the smooth pulling of the wire and affect the production.

The surface of the galvanized wire deposition layer before galvanized to remove the surface film layer, surface inclusion and other defects to the local, can be found and treated by conventional technology. Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless.

Arrived in other ways can’t end effect of the inclination of hook flower network structure in essence is void, water permeability, the natural effect of groundwater and filtering effect has a strong inclusive, suspended in the water content and silt accumulation in fill in crevices, applied to mountain protection, is conducive to the growth of natural plant, beautify the grass spraying to arrive late his curing effect, Gradually restoring the original ecological environment is a perfect connection between beautification and protection.

Hot drawing is the heating before the wire enters the die hole, mainly used for high melting point wire drawing; The temperature drawing is carried out by heating the heater to the range of temperature, mainly used for galvanized steel wire, difficult to deform drawing.

(2) can be used as breeding net, sheep net, cattle net, chicken and duck, isolation chicken and duck house, play the role of poultry protection;

Because of the beauty, art, or in specific severe corrosion environment, galvanized layer can be applied to the above paint duplex system, as long as the paint system selection is correct, easy construction, its anticorrosion effect is 1.5~2.5 times better than the single paint and hot dip zinc life combined. With zinc layer to protect iron and steel, in addition to hot dip galvanizing method, there are several other methods, generally widely used, corrosion prevention effect is good and good economic benefits, hot dip galvanizing method.

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.

When the coating of large galvanized wire is blistered in the process of galvanizing, the bath temperature should be checked first. If the bath temperature is not low, and then strengthen the removal of oil before plating, to prevent the base metal in acid corrosion. If you pay attention to these problems, the bubbling phenomenon still exists, it should pay attention to the dosage and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, to reduce the content of additives, observe whether the bubbling phenomenon is improved. If there is no improvement, check whether the additive has been stored for too long or whether it contains too many impurities.

Large volume galvanized wire welding net is made of high quality low carbon steel wire row welding, and then cold plating, hot plating, PVC plastic and other surface passivation, plasticizing treatment, net surface leveling, mesh uniform, welding spot firm, local machining performance is good, stable, anticorrosive, anticorrosive good galvanized welding net types. Galvanized welding net simple and practical judgment quality mainly from the following points:

Spring wire shall have high tensile strength, elastic limit, endurance and fatigue strength, and be resistant to shock and oscillation. The objectives of strength and endurance, especially the prevention of alteration cracks, are key to the consumption of spring steel wires. The inner and outer quality of wire rod directly affect the function of steel wire.
