The spray blade has strong adhesion and mechanical strength, and is widely used in the isolation and protection of the boundary of grassland and railway, as well as the protection of garden apartments, units and prisons. The following Haorong for you to introduce the characteristics of spray blade rope.
- The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tightly bound with a very strong transparent plastic bag. The outer layer of coated iron wire is wrapped with white braided cloth, and the outer layer of galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process. One end of the wire must be clearly marked and the other end left on the outer layer for easy connection by other wires.
- Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. It has strong structure, flat surface, good corrosion resistance, oxidation resistance and so on.

There are many ways to choose the blade stabbing rope, and it is necessary to choose reasonably when choosing. Blade barbed rope is very good in the market reputation, and different types of blade barbed rope can play different roles, so how should we choose blade barbed rope? What are the main points?
-
The galvanized layer forms a particular metallurgical structure that is capable of accepting mechanical damage during transport and use. Every part of the plating can be zinc plated, even in dents, sharp corners and hidden places can be fully maintained. The galvanizing process is more convenient than other coating construction methods, and can avoid the required time after the installation on the site.
- The zinc layer on the galvanized wire has good ductility, can be cold blanking, rolling, bending and other molding without damage to the zinc layer. The zinc layer of galvanized wire with thick zinc layer has fine crystallinity, uniform and no void, and good corrosion resistance. The zinc layer obtained by electrogalvanizing is very pure and corrodes slowly in the gas, liquid and fog of acid and alkali, which can effectively protect the steel matrix. Galvanized layer can also be chromate passivation into a variety of colors, beautiful and generous, with good decoration.
-
- Zinc-coated wire is dipped in molten zinc with high production speed and thick but uneven coating. The thickness allowed by the market is 45 microns, the color is dark, the consumption of zinc metal, and the base metal to form infiltration layer, good corrosion resistance, hot dip galvanizing can be maintained for decades in the outdoor environment.
- Galvanized hook net standard is thorough, mesh planning: 3cm-20cm, wire planning: 1.2mm-4.5mm, galvanized hook net 6000 square meters, some standards have in stock. Benefits: The selection of low carbon steel wire, the surface of cold galvanized (electric galvanized) hot galvanizing anti-corrosion treatment, net wire strong, strong protection, anti-corrosion time is long.
- Stainless steel wire drawing is a metal processing (stainless steel) process, is a popular surface treatment technology in stainless steel and aluminum products industry today. It is a wire drawing effect treatment for stainless steel and aluminum products. So galvanized wire and stainless steel wire are two different products. In order to remove the surface film and surface inclusions on the surface of the deposited layer, the defects can be found and treated by conventional techniques. Excess foam is caused by soap and surfactant saponable fats brought into the tank.

Heavy hexagonal mesh is made of steel wire by special machinery woven hexagonal mesh mesh. This kind of net, after cutting, assembly can be made into fence net, mountain hanging net, vegetation three-dimensional network, combination and so on.
-
The large roll of galvanized wire is violently extinguished in oxygen and sparks radiate, while the sodium block and magnesium bar are extinguished in oxygen and no sparks radiate. This phenomenon is determined by the composition of large rolls of galvanized wire. The large rolls of galvanized wire used in the experiment are pig iron or steel wire, both of which are alloys of iron and carbon (complex substances containing the elements iron and carbon). When the carbon in galvanized wire is extinguished, carbon dioxide will be produced, and the solid will be changed into a gas, and the volume will shrink rapidly.
- 3. The front and back twist barbed wire has a beautiful appearance
-
After the column is installed and secured, the net can be connected directly to the Internet. The tools required for this step must be special spanner, casing and matching screws. Stand the net in the middle of the two columns, and then force upward to align the net with the connecting accessories of the column.
-
Barbed rope is to use iron wire, through winding machine, through a variety of weaving technology, wound in the main line (stranded) made of isolation protection net. There are three ways to twist the barbed rope, as detailed below.
- I’m going to take the middle one. Steel wire galvanized is very important, must master galvanized, galvanized, because there are many methods, but we first must choose hot plate, welding mesh material, and then excitation, and diameter of steel wire is mainly according to the construction requirements, as well as the requirements of the range of application.
- There are generally PVC plastic coating on the cattle net is in the original galvanized steel wire on the cover of a layer of dark green or gray plastic mold, to avoid the corrosion of wire diameter, is conducive to the progress of the anti-rust function of wire diameter. So the better the raw material, the higher the price. Zinc aluminum alloy cattle net is the best metal net on the market, the price is higher than hot dip galvanized raw materials. The service life is about 80-90 years, with excellent anti-corrosion function.
-
The rest of the common application of galvanized iron wire is screen preparation or welding, construction mesh welding commonly used specifications for 2.0mm or 2.5mm wire diameter, welding size of 1M *2m or according to the height of the floor to customize the size. There is another is the use of electric welding net. The wire diameter of the welding net is relatively fine, and is divided into galvanized wire welding and galvanized welding. That is, galvanized wire is directly welded or black iron wire is welded into a net and then in the two galvanized.
-
When large rolls of galvanized wire are used to bind and reinforce the goods, corresponding binding methods should be selected according to the fastening node conditions of the strengthened goods, such as opening binding, opening binding, insertion binding and so on. The insulation layer of semi-hard and soft insulation products shall be based on the diameter of the steel pipe and the size of the equipment. Large rolls of galvanized wire or glue are tied together with a width of 60mm. The binding interval of semi-hard insulating products shall not exceed 300 mm; The larger length of felt and cushion shall not exceed 200mm, and the number of belts shall not be less than 2.
- Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.

2. Check the stabbing rope of the blade on time
- Twisting hexagon mesh production factory is the selection of low carbon steel silk woven, mesh structure he has corrosion resistance, high strength and ductility and so on. The diameter of steel wire can reach 2.0mm-4.0mm. The surface of steel wire is usually used for hot-dip galvanized maintenance. The thickness of galvanized maintenance layer can be made according to the needs of customers.
-
Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.

Choose birds, raise birds before you need to choose the right birds, generally choose young birds, or minor birds, the requirements of health, strong activity, these birds are relatively easy to keep.
-
Speaking of pets, we have to talk about parrots. Because it’s easy to take care of, and it can talk, talk to you, and make you laugh. Parrots love to climb, so there is a cage with bars that are made up of horizontal bars rather than vertical bars, because this makes climbing easier for the parrots.
-
Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.

Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
- 3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag
- Spray hook net wholesale used in the stadium, mainly used to play the role of the game ball isolation block, the field isolation zone. Stadium Seine usually use woven net as the main raw materials, it is different from welding net, woven mesh with mesh uniform, flexible, convenient and has good elasticity, impact resistance, etc. Product characteristics, the stadium fence is divided into two categories, category is packaged stadium fence, also known as Seine bulk type, another kind is with a border plastic spraying hook flower wholesale network. Both kinds of stadium purse Seine have advantages and disadvantages.
- The principle of wire mesh mesh size, wire, square meters of steel content, galvanized amount, etc., to consider the corrosion resistance of wire mesh and the safety of the system! Wire mesh galvanized than wire diameter more fierce, galvanized quantity is very important, must be hot plating, welding after plating than plating after welding, as for wire diameter, induction and consideration of site construction and meet the needs of Ann.
- If adult dogs and puppies touch noses out of love, then adult dog nose touching is more meaningful. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
