Post time: 21-03-23Removal 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. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Two is to pay attention to the storage and use of galvanized wire products, according to the actual environmental standards to choose different specifications of galvanized wire products;
- The management system of the rinsing water after wire pickling should be discharged regularly and regularly, and the rinsing water should be kept clean and low acid value as far as possible. It is more appropriate to control the pH value of 3. The concentration of plating aid should not be too high. The hot plating wire must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is added without reference to the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.
- After a long time of use, it will not rust like the corrosion layer on the surface of hot dip galvanized barbed rope, because the internal material of stainless steel barbed rope is the same as the material on the surface.
For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by the customer. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this is very important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized wire, the weight can reach 300kg/ roll or 800kg/ roll.
- 4, barbed wire protective net and culvert intersection, such as the ditch is narrow, barbed wire barbed wire protective net can be directly crossed, the ditch is wide, barbed wire barbed wire protective net is difficult to cross, can take the treatment method of bridge, channel.
- After the wire mesh appears black spots, you can choose the appearance of treatment to deal with this problem, such as galvanized, paint, dip plastic to deal with, after the appearance of the welding mesh surface smooth and bright, beautiful and generous.
The iron is clean and clean, and then solvent treatment, after drying immersed in zinc liquid, iron and molten zinc reaction to produce an alloyed zinc layer, the process is: degreasing – washing – pickling – assisted plating – drying – hot dip galvanizing – separation – cooling passivation. The thickness of the alloy layer of hot plating wire mainly depends on the chemical composition of the steel silicon content, the size of the steel cross-sectional area, the roughness of the steel surface, the temperature of the zinc pot, the time of dipping zinc, cooling speed, cold rolling deformation, etc.
Fence use: The use of the fence is generally one meter two to two meters a height of the impregnated welding mesh, mesh mostly 6cm, wire diameter from 2mm to 3mm.
If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.
- 3, twisting hexagonal net factory weight, the greater the weight, the more sufficient material.
The barbed wire factory will store the inventory of the barbed wire blade in the appropriate place because of the understanding of the product characteristics.
Cats are agile and good at jumping. Eat fish, rats, rabbits, birds, etc. The reason why cats like to eat fish and mice is because cats are nocturnal animals. In order to see things clearly at night, they need a lot of taurine, and mice and fish contain taurine, so cats are not only because they like eating They eat fish and rats, and they eat because of their own needs. Since cats are widely raised, the market prospect of cat cages is very promising.
Galvanized electric welding mesh refers to the mesh made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, become used in residential communities. Traditional electric welding mesh using iron bars, aluminum alloy materials, need to use welding and other technology, and the texture is soft, easy to rust, single color.
Post time: 19-04-23- Suitable for general engineering building wall, pouring concrete, multi-storey building, etc., in the structure of heat preservation and heat insulation system plays an important role, when the construction will be hot dip galvanized welded wire rack together wall of heat preservation and heat insulation board placement will be concrete pouring mold inside, outside the wall heat preservation and heat insulation board and one kind of live, after ripping into heat preservation and heat insulation board and wall body. The coating on the surface of the welding core is called the coating.

Post time: 20-10-22- Two, cold galvanized wire production process of galvanized. Galvanizing is the core process in the production of cold galvanized wire, mainly by soaking the steel wire in a molten zinc solution to form a zinc layer on its surface.
This process has no mold, low processing cost, easy forming, can process a variety of shapes and other characteristics are widely used. But the products of the guardrail are powder impregnated plastic. According to whether it needs heating, it is divided into hot dipping and cold dipping. According to the raw materials of dipping, it can be divided into liquid dipping and powder dipping. Hot-dip galvanizing, as a metal anticorrosion method, is usually to put the steel structure to be derusted into the zinc liquid at about 500℃, so that the zinc layer is attached to the surface of the steel structure.
- Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by the customer, ensure that the metal wire can achieve the role of rust and corrosion prevention, and meet the service life required by the customer. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound with an inward end to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test. This item is determined according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
Post time: 29-07-22The production of large rolls of galvanized wire iron can be divided into two categories, is directly from the iron ore after iron stroke exercise out of the metal, the composition of the ore is iron oxide, silica and other miscellaneous stone.
Post time: 13-03-23- Now hexagonal mesh is used in a large number of Bridges, piers and bridge buttress inclined plane protection, bridge buttress inclined plane there are many kinds, people according to the inclination of the inclined plane to choose the right hexagonal mesh, and in the case of steep slope, people will use gabion mesh gravity protection wall. As we all know, the use of hexagonal net for protection can protect the natural environment while protecting the bridge, which can not only green the ecological environment, but also prevent soil erosion.
- 5, there are no special requirements: such as whether to shrink packaging.
What kind of wire mesh fence should be used for chickens, ducks, geese and other light poultry? The so-called good refers to the high cost performance, that is, the use effect can be achieved, such as the size of the mesh, the size, etc., and the cost can be reduced to the greatest extent.
