One of the key advantages of using drill extension rods is their versatility. They can be easily attached and detached from the drill string, allowing for quick adjustments to the drilling depth as needed. This flexibility is crucial in complex drilling operations where varying depths are required This flexibility is crucial in complex drilling operations where varying depths are required
Post time: 28-04-223. The transport, storage and use of the binder of galvanized wire mesh should adopt safety and fire prevention methods according to the relevant regulations, so as to be safer.
- Hook net use value is still very high, has a very good sex, and its manufacturing concise generous, beautiful, not in high temperature will fade, you can save a sum of maintenance costs, but also according to the different needs of the site to change the shape, to meet the needs of the site.
- Wire rod to stop normalizing or soxaustenitizing treatment, large specifications with spheroidizing annealing instead. In the middle, especially before the waste product drawing process of thermal disposal throughout the selection of soxaustenitizing disposal. Decarbonization should be prevented during thermal disposal. Sulfuric acid or hydrochloric acid pickling was used to remove the oxide sheet after hot treatment. Coating (see lubrication carrier) can be dipped in lime, phosphating, borax disposal or copper plating.
- Weaving process: plain grain
- The design is designed not only for ease of installation, but also for the ability to achieve such installation in harsh terrain conditions such as cliffs, with little anchorage and little excavation for quick and easy installation. Based on the characteristics of heavy hexagonal mesh double stranded structure, even in the case of wire damage can also withstand the impact of falling rock.
Post time: 25-07-22- 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.
3, pay attention to the width of the cage seam
Now hexagonal net is used in a large number of Bridges, piers and bridge buttress inclined plane protection, bridge buttress inclined plane there are many kinds, people according to the inclination of the inclined plane to choose the right hexagonal net, when the inclined plane gentle, people generally use gabion slope protection system, and in the case of steep slope, people will use gabion mesh gravity protection wall.
Hook mesh wire diameter has thickness, fine wire diameter is generally 0.5mm-2.0mm, thick wire diameter can be in 5mm-22mm. Hook mesh is also customized according to different uses, in general, fine silk can be woven into a relatively small hole, thick silk is generally called heavy hook mesh, mainly used in the screening of stones and coal, in short, hook mesh has an important role in many professions.
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.
First, the effect of tensile strength or hardness of steel wire
The prepared black wire welding net is placed in environmental protection galvanized equipment for galvanized treatment. The surface of galvanized welding net is evenly covered with a layer of metal zinc. The corrosion resistance of zinc is very good and it is not easy to be oxidized. The wire diameter error of galvanized welding mesh is very strict, and the gap should be controlled at about 0.02 mm. But whether the tension of an electric welding mesh is qualified, can only be tested by professional tools.
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
Post time: 08-08-22And the role of wire mesh in the exterior wall plastering if from an Angle to sail a method of anti-falling, the role of anti-cracking is relatively small, because of the problem of orientation; And about the external insulation system is used in the tile veneer, as for the role should also be anti-drop followed by anti-cracking, so the grid should be selected 10×10×0.6, these are some experience selection, grid conversion from the national provisions of the wire mesh standard, choose the level of steel conversion.
- 1, first of all, the net surface is smooth, mesh are four lines, pitch is the same, whether the weft wire bending (note: the net width is the length of the weft wire), normal weft wire passes through the straight wire of welded wire mesh, with accurate time and the silk repeated welding, make the pitch of welded wire mesh is consistent, with smooth surface, into a square hole, when the net vertical position from the top downwards see, weft wire is straight.
Post time: 05-07-22Unless 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.
Post time: 14-06-24- 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.
Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
- 3, whether positive and negative twist, whether bilateral silk is needed.
Post time: 03-08-22Cold wire drawing is a kind of cold processing of metal. The raw material is wire rod, which is produced by peeling, galvanizing and other processes. Galvanized cold drawing is used more in building materials. Its testing standards are also different. The strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction. It saves the construction steel in building materials, and also reduces the cost of the project. It also plays a very important role in the structure of concrete.
On the highway, the barbed wire protective net is generally used to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of highway land and other issues of traffic safety facilities. There are many forms of barbed wire protective nets, commonly used are metal, woven nets, barbed wire and evergreen green gracilaria. In the densely populated areas set up metal woven net, people and animals are less sparse areas of the form of barbed wire, in the toll station, service area and other sections of the structure of hedge and barbed wire. In the past two years, considering the aesthetic problem, some highways in the Pearl River Delta region adopted the fruit plastic spot welding mesh (usually said guardrail mesh), the barbed wire protective mesh is more beautiful, but also durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beauty of the section available.
- 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.
- Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
