The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use. Selection of low carbon raw materials, through wire drawing, annealing processing, soft and strong tensile resistance. Finished products coated with anti-rust oil, not easy to rust, according to customer requirements into bundles, each bundle of 1-50Kg, can also be made into U-shaped wire, broken wire, internal plastic and external hemp packaging, mainly used for binding silk, construction silk, etc.
Steel mesh manual binding line of the joint simple sliding, steel and concrete strength is weak, simple crack. The welded joint can accept not only pressure but also shear force. Longitudinal and transverse steel bars form a network structure, which plays a bonding anchorage effect. The number of solder joints per unit area is added when the diameter of the wire mesh is small and closely spaced. More conducive to strengthening the crack resistance of concrete, can reduce more than 75 percent of the attack of steel mesh cracks is a new, energy-efficient steel mesh structure, used in beams and columns, floors, roofs, walls, concrete pavement, bridge deck paving and other industrial and civil buildings.
In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.
In general, the cost of hot dipping zinc is lower than that of other maintenance coatings. The reason is very simple. Other maintenance coatings, such as sand painting, are labor-intensive processes, whereas hot dipping zinc processes are highly mechanized and tightly controlled in-plant construction. Hot dip zinc coating can be visually and briefly tested for non-destructive coating thickness.
3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag
With the rapid development of market economy, all walks of life are improving the production process and quality of products, galvanized iron wire industry is of course no exception. However, because of the different types of galvanized iron wire, its characteristics and production technology are also different. Galvanized wire selection of high quality low carbon steel rod processing, is the selection of high quality low carbon steel.
Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction
Second: positive and negative twisting rope cost-effective
First of all: twist and reverse thorn rope durable
Generally, due to wet weather and more precipitation, oxidation and rust of binding iron wire NetEase occurs, so we should better store and use galvanized iron wire to avoid rust as far as possible. About the barbed wire, the surface of the barbed wire attached a layer of galvanized layer, the galvanized layer if too thick will not meet the SGS environmental standards. But if it is too thin, it is easy to oxidize with water molecules and rust.
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.Stainless steel barbed rope is often used in various engineering projects because of its good anticorrosion ability, but it is difficult to be accepted by ordinary families because of its high price. So what material of barbed rope has better anticorrosion ability?
The most obvious gap in a short period of time is the cross section of this piece, hot dip galvanized wire because it is surface anti-corrosion treatment, so in the cross section of this piece will appear rust, and stainless steel wire because the internal raw materials and surface raw materials are consistent, so there is no such situation. All can do spring can be called spring steel wire, and high carbon is the highest carbon content. Features: WITH high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is OK, but welding function and cold plastic deformation ability is poor.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, The softness is also very uniform, the color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry, etc.
Ordinary blades installed on the walls of the barbed wire fence height in two metres of general construction cost in more than a dozen yuan a metre, but if the prison on the height of the wall construction modest have already reached the four or five meters so that every one meter of the cost of construction in 30-40 yuan, mainly because the work high above the risk is bigger. The construction cost is different, but the price of the blade barbed rope is the same. The construction cost is often higher than the product. In this way, the blade barbed rope factory recommends customers to use the blade barbed rope with better quality to avoid the tedious time and cost of subsequent removal and installation.
And the air humidity is large, continuous rainy weather, or the environment with large acidity in the air is easy to rust. 304 stainless steel material, if the surrounding environment is too poor will rust.2, galvanized wire mesh molding sheet storage ground should be flat, according to the symbolic requirements of the accumulation of regular, height should not exceed 2M, and away from heat sources, avoid exposure.
There are various specifications of barbed rope, which can be divided into two categories: ordinary barbed rope and blade barbed rope.
Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives should be used to obtain a coating that meets the requirements of this standard. Light treatment should be carried out after light plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied for activation for 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
