Next, the drilling equipment must be properly set up and calibrated. This involves ensuring that the drill bit is positioned at the correct angle and depth, and that the drilling parameters (such as rotation speed and feed rate) are optimized for the specific limestone being drilled. It is also important to use a lubricant or cooling fluid to reduce friction and prevent overheating of the drill bit It is also important to use a lubricant or cooling fluid to reduce friction and prevent overheating of the drill bit
The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.
Post time: 14-02-23- 2, can quickly let the dog develop home habits, let it learn to wait for the owner to take it out, prevent it from making the home dirty, dirty its nest.
- ③ Galvanized iron wire shall not be damaged when it is tightened.
- 5, when limited by the terrain, the barbed rope barbed rope protective net before and after the continuous setting, take the place as the end of the barbed rope protective net, and deal with the end of the sealing.
Appellation: Hook fence is a variety of guardrail. The diameter of the opposite side of each mesh is generally 6.5cm-14cm. The thickness of the wire used is generally from 3.5mm to 6mm. Wire material is generally Q235 low carbon wire. The wire is welded by gimmick into decorative hook mesh black. The general size of the net is 1.5 meters X4 meters, 2 meters X4 meters, 2 meters X3 meters. The general surface treatment is cold (electric) galvanized treatment. There are also hot dip galvanizing, dip plastic, spray plastic. But overall, 99 percent is cold (electric) galvanized.

- In fact, although galvanized hook net is a useful material for iron products, but fundamentally speaking, modern hook net through continuous transformation and improvement, even if it seems to be not useful products, also have a role in its use, here we can turn our attention to people abandoned galvanized hook net.
- A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.
- The most obvious gap in a short time is the cross section of this piece, hot dip galvanized barbed wire because it is the surface anti-corrosion treatment, so in the cross section of this piece will appear rust, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.
Unless the stainless steel blade barbed rope produced now is a specially customized model, it is generally produced with a tool length of 22mm, which is what we usually call bto-22 type. It is not necessarily such a specification from 11mm to 65mm there are specifications. Unless the customer insists on customizing the specified length, the barbed rope manufacturer produces the bto-22 stainless steel blade barbed rope.
The whole welding process of galvanized steel wire mesh does not need special technological methods, good weldability. However, in a few cases, the welding process will present difficulties: the converter steel produced by the old smelting method has high nitrogen content and high impurity content, resulting in high cold brittleness, added aging sensitivity, lower quality of welded joints, and poor weldability.
When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.
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.
We must have a certain understanding of the hexagonal network, we are the beautiful appearance of the hexagonal network, hexagonal network is not only very beautiful appearance, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
- Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is to use the lead screw above the zinc pot, the length of the distance to the ceramic sinking roller. Thick wire diameter zinc dipping time should be long, fine wire diameter zinc dipping time should be short, zinc dipping length is in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire, is an aspect of maintaining the uniformity of zinc layer.
High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer machine, we can generally judge whether the quality of galvanized wire is high quality.
Post time: 16-02-23- It is recommended to have a brush, comb or rake ready before bathing your dog; Shampoo, conditioner, shower gloves, tether, bath mat, floor drain lid, spray, towel and shower shower.
- 2, pasture installation of thorn rope spacing, if it is cattle or horses due to the larger size, the spacing can be appropriately relaxed. But if it’s a sheep, it’s a smaller animal and you have to make it a little bit narrower.
Hexagon mesh weight calculation method is: hexagon mesh weight calculation method: wire.× wire.× 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 warp.× Warp.×2x length x width ÷8×3=kg
Post time: 28-07-22- With a large pickpocket used for steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. The extracted zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption. This is one of the measures to reduce zinc consumption, but it is also a real problem, which has not been solved for many years.
Hook mesh we usually see everywhere, in fact, hook mesh is a kind of fence, like the highway, stadium fence, road fence, etc., have hook mesh. So what are the effects and advantages of the use of hook net?
The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the grease should be able to protect the fiber core from decay and corrosion, the iron wire moistens the fiber, and lubricates the wire rope from the inside. The surface is coated with oil so that all the wire surface in the rope strand is evenly coated with a layer of anti-rust lubricating grease, which is used for the mine rope with friction lifting and mineral water, to be coated with black grease with increased wear and strong water resistance. Other uses are coated with red oil oil with strong film and good rust resistance, and require it to have a thin oil layer, which is easy to keep clean during the operation.
With the increasing use of hook mesh, the method of bridge rail is also different. The height of the outer railing of the walkway or seat belt should not be lower than 1.10 meters. 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.
In reinforced concrete structure, the crack width of cold wire drawing is smaller than that of circular steel bar or even that of hot rolled thread bar. So cold wire drawing is more popular in the construction industry. The material for cold drawing is made of steel bars and can be simply explained how it is made, that is, its production process is simple. It’s based on steel bars, which are constantly stretched evenly, stretching the bars into something very thin, like wire drawing, without plasticity.
- The common specifications of small hexagonal mesh in production are: the width is 1.22m, and the commonly used width is generally 1m. In terms of length, there are basically no restrictions on small hexagonal nets. 1-100 meters can be produced. The production wire diameter of small hexagonal mesh is generally No. 27 wire to No. 18 wire, and the aperture size is 0.95cm-5.08cm.
- Packing and binding galvanized wire is in the liquid state of zinc, after a messy physical and chemical effect, not only on the steel plated thick pure zinc layer, and also generate a zinc-iron alloy layer. This kind of plating method, not only has the corrosion characteristics of the electric galvanized wire, and because of a zinc alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali fog and other strong corrosive environment.
