The dog cage is a resting place for the dog, do not put it in the place where the family is walking, teach the children, when the dog is in the cage, do not disturb the dog.

There are many important details that need to be paid special attention to during the production of barbed rope or blade barbed rope by the barbed rope factory. If any improper, it will cause unnecessary losses.

1, want to a person or friends together, leave the dog a person at home, so that it will not be hurt, the dog is comfortable, safe, but not because of loose and develop bad habits, at this time you can use the pet cage.

Any application environment, users want a better the strength of the welded wire mesh, only need to improve its intensity, will make better the habit of using demand, but to be improved in the strength of this product, also need yo have a variety of conditions, will need to see factory in produce what kind of material, the strength of the product also is the material strength, But a manufacturer in the data does not fit the strength requirements, after all, there is no way to make the strength of the product progress, so this is the condition to.

Different supports are used for different installation environments. In the past, the blade barbed wire was not easy to fix, and the installation environment was often steep. Therefore, special tools must be used to fix the blade barbed wire to prevent it from being improperly installed.

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.

With the increasingly extensive use of hook mesh, the method of bridge rail is also different. The height of sidewalks or seatbelt outer railings should not be lower than 1.10 metres. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.

Raw material of wire mesh sheet cold drawn low carbon steel wire base material can choose low carbon steel hot rolled disk bar or hot rolled smooth steel bar. The base material number and diameter of cold-drawn low carbon steel wire can be confirmed according to the rules in the table below. During the cold drawing process, the surface shrinkage rate of each drawing should not be greater than the wire mesh before cold drawing. Annealing shall not be carried out during wire drawing. If butt welding is required, the same production unit and base material of the same number should be selected. The appearance quality of wire mesh should not affect wire drawing. When the welding function is poor or brittle fracture occurs, special inspection should be carried out according to relevant standards.

The application of electric welding net is more widely, at present it has replaced the use of other parts of the wire mesh, the cost of electric welding net is lower, the production speed is very fast, so it is very popular. Welding net galvanized before the need for processing is recrystallization annealing, because the welding net must maintain a no oxide and no other impurities of pure iron active surface, if you can not keep its surface clean will lead to a bad galvanizing effect, galvanized layer and iron material is not closely combined, so this step is necessary.

The main raw material of blade barbed rope is galvanized wire and galvanized sheet, because the price of galvanized sheet is more expensive than galvanized wire, so it is directly reflected in the price of the sales of blade barbed rope. There is also the difference in processing technology also led to the difference in the price of the blade thorn rope. The traditional barbed rope is mechanically twisted, which uses less labor and has high production efficiency. But the blade is after two mechanical processing in the manual processing operation before the appearance. So whether from the labor force or from the production efficiency also said there is a large gap. These factors lead to the price of blade thorn rope is more expensive the main factor.

Any application environment, users want a better the strength of the welded wire mesh, only need to improve its intensity, will make better the habit of using demand, but to be improved in the strength of this product, also need yo have a variety of conditions, will need to see factory in produce what kind of material, the strength of the product also is the material strength, But a manufacturer in the data does not fit the strength requirements, after all, there is no way to make the strength of the product progress, so this is the condition to.

The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.

The weight calculation method of hexagonal net is: the weight calculation method of hexagonal net: silk meridian.× silk meridian.× base x length x width ÷2=kg base: 1/2′=2.151′=1.273/4′=1.65/8′=1.875/4′=1.091′x1/2′ : 3′=0.4 silk warp. x silk warp. X 2x length x width ÷8×3=kg

Galvanized wire mesh is divided into hot dip galvanized wire mesh and cold galvanized wire mesh. Galvanized steel wire net selects the high quality low carbon steel wire, iron wire factory made by precision of automation machinery welding technology processing, smooth surface, firm structure, integrity is strong, even if the local cutting of galvanized steel wire net, or local also under pressure from loose phenomenon, after molding, wire mesh galvanized corrosion resistance good, has the advantage that the general steel mesh does not have.

In the process of composite plating, it is necessary to stir the plating solution to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire.

Excellent anticorrosive makes its popularity in the feed, the net surface smooth and tidy, increased the look and feel, can be adornment effect, this characteristic makes it to show in the mining industry, due to high quality with low carbon materials as raw materials, to make it unique general iron mesh screen does not have flexibility, determine its plasticity in use process, Thus can be used in the hardware process of deep processing and manufacturing, complex wall batch swing, underground leakage prevention cracking, light mesh body, so that the cost is much lower than the cost of iron screen, more able to understand its economic and practical.

Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
