In order to remove the photosynovium and oxide remaining on the surface of galvanized iron wire after drawing or heat treatment, it is necessary to do the surface treatment of galvanized steel wire before plating. The common surface of low carbon steel wire is the light synovium or oxide of animal or vegetable oil; Medium and high carbon steel in addition to contain animal or vegetable oil components.
- The acceptance of cold-drawn low carbon steel wire shall be conducted according to the same production unit, the same raw material, the same diameter, and shall not exceed 30T for an inspection lot, and check the base material into the factory or out of the inspection statement. The inspection items for each inspection lot are appearance quality, diameter error, tensile test (including tensile strength and elongation) and repeated bending test.
- Professionals tell us that the surface of high zinc barbed rope is not particularly smooth because of zinc, when holding the two products a comparison, you can find. Although the general zinc cord zinc layer thin but relatively smooth. Another way is to have a special instrument to measure, this kind of equipment is expensive, ordinary users can not buy the measurement. The last method is that there is a level gap in the sense of light, zinc thorn rope is bright and high zinc thorn rope brightness is slightly darker, so customers do not think that the appearance of the better product is good quality when buying.
- 2. Choose the dog cage according to the material
Hot wire mesh in the building wall engineering mainly played the anti-crack effect, inside and outside the use of specifications are not the same. Hot dipped wire material choose low carbon wire, through automation welding precision machinery processing after forming, surface treatment by zinc immersion process, galvanized barbed wire surface smooth and tidy, uniform structure strong, the overall performance is good, even if the local cutting or under pressure will not loose phenomenon occurs, it is the iron mesh strong anticorrosion performance in one of the widely used net class.
- In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The exact amount of stinging and use the warp need to increase after a series of professional measurement on the loss of raw materials and so on factors to calculate.
- 2. Take out the items in the cage. First, rinse most of the dirt off the cage with water, and then wipe the dirt around it with a wet towel; And then clean the cage.
- In order to ensure the electrical conductivity of steel wire, manufacturers need to follow a number of standards and regulations. For example, in the galvanizing treatment of steel wire, the international standard ISO 1461 should be followed to ensure uniform zinc layer thickness and surface gloss. In wire drawing processing, excessive stretching should be avoided so as not to deform the wire or lose its mechanical properties.
The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail and extend the service life of the product.
- 2. When there are channels, ponds, lakes and other natural barriers on the side of the road, there is no need to worry about people and animals entering and illegally occupying the road land.
With the development of mining industry, pig iron classification in Our country has been very extensive, to meet the needs of the machinery industry. Generally speaking, iron wire factory produces galvanized iron wire iron can be divided into two categories, is directly from the iron ore through iron tracing exercise out of the metal, the primary components of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, the elements such as carbon, silicon, manganese and so on are mixed in, so that the refined data is called – like general pig iron, also for the initial grade of the material.
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 tied with a very strong transparent plastic bag. The coated iron wire is wrapped with white braided cloth, and the galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process.
- In want to use barbed wire fence ground road at both ends of each set up a stake, and then from the two stakes, every 30m to set up a stake, until the installation of the line is full of stakes, so installed barbed wire net is a straight line.
Post time: 13-07-22- Combined restrictions of fence network and maintenance network: Plot fence network, garden villa, private swimming pool, courtyard on the lawn, city scene, municipal transportation, sports venues, airport port, office school, military equipment, prison farm, industrial park, tourist resort, distribution center, The specifications and parameters of the fence network are as follows: 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400 (mm) : 2000, 2500, 3000 mesh spacing (mm).
(2) Packing and binding galvanized shaft wire order notes: ① the galvanized iron wire shall not be damaged when the tightening. (2) Stop the use of more than two strands of galvanized iron wire around the operation method. ③ The diameter of galvanized wire for pulling should not be less than 4mm, and the diameter of galvanized wire for binding should not be less than 2.6mm. (4) Galvanized iron wire shall not be used as waist hoop down reinforcement, usually not used as a whole binding. Warehouse galvanized wire is mainly used to block and distinguish the function of the area, warehouse galvanized wire is one of the primary use of galvanized wire, warehouse galvanized wire primary layout features are as follows: layout: Column mesh frame, column to choose square steel pipe, galvanized wire frame is also a small square pipe as the data, column and mesh frame corresponding direction are welded connecting ear piece (flat iron), column and mesh frame through the connection of the ear piece bolt fixed, column bottom welding plate, column bottom plate through expansion bolts and fixed on the ground.
Compared with galvanizing, hot-dip galvanizing has lower production cost and less environmental impact than galvanizing. Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, electric power transmission, shipbuilding and other industries.
Post time: 13-12-22Even so, when they come out, they will uncover the mess, even though they know they will be punished, but only in a cage.) If you have time to refer to some foreign dog books, also strongly advocate cage training as a puppy. Before starting cage training, the cage is padded with a water bottle, some fun toys and bones to chew on. The cage door must be opened. Order the dog into the cage, then lure it into its new den with tasty cookies.
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.

There is also in the use of places, blade thorn rope is generally installed and used for the border, walls, prisons and so on, and galvanized thorn rope is in the orchard, fence livestock and so on a large area of installation, although the use of large, but not as high as the use of blade thorn rope and grade, so this is the main reason for the high price. Finally, for the blade barbed wire, the general installation site has high requirements for the protection level, so the quality of the product is also relatively high. But the ordinary galvanized barbed wire has relatively low requirements for the quality in the processing process due to the casual requirements at the installation site.
- Some herdsmen avoid the intrusion of wild animals and other people’s livestock and from time to time to increase the grassland grassland stainless steel barbed rope fence net, so that the grassland grassland stainless steel barbed rope fence net has become a barrier to all kinds of wild animals. It is in herders’ interests to increase the number of their livestock, but consciously raising barbed ropes not only directly frightens and harms wildlife, but also cuts them off from food and migration.
