In addition to breaking up hard materials, pneumatic jack hammers can also be used for a variety of other tasks. For example, they can be used to remove old grout or plaster from walls and ceilings, or to break up frozen ground before excavation For example, they can be used to remove old grout or plaster from walls and ceilings, or to break up frozen ground before excavation
The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.
Post time: 02-02-23- Welded wire mesh can be made into mesh form, the net surface jinsu or coating process, can be used in welded wire mesh and surface to form a layer of protective film, can effectively make the wire with the outside world with water or corrosive substances isolation, can achieve the effect of growth time, also can make the mesh surface present a different color, make the mesh to achieve the effect of beautiful. After the dip plastic mesh is usually used for outdoor, and column links, can play a protective effect against theft.
Post time: 29-08-22The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.
Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.
Galvanized wire is divided into hot dip galvanized iron wire and galvanized iron wire according to the production process. It has the characteristics of high tensile strength, good softness, zinc layer uniformity, corrosion resistance, beautiful color, good smoothness, strong adhesion and corrosion resistance. Hot dip galvanizing has better protective properties than electric galvanizing, so it is an important protective coating for steel parts used in harsh working conditions.
You can also buy a cage from other places. You can choose the cage you like or find suitable on the website. For example, a pet store, supermarket, pet products website, etc., it is recommended that you buy metal cage, with a metal tray underneath, of course can also be of stainless steel and plastic, is plastic easily damaged by the dog bite, plastic tray is easy to be a dog of uric acid corrosion, but also show the low end of the plastic products, beautiful, durable.
Post time: 19-12-22- Galvanized hexagonal net is a galvanized metal wire mesh, the shape of the grid is hexagonal.
Post time: 06-01-23- In addition, before the steel wire enters the zinc liquid, covered with a layer of insulation material containing zinc oxide reducing agent, can reduce the heat loss and zinc ash floating. In addition, adding zinc-5% aluminum-mixed rare earth alloy to the zinc solution, when the zinc solution contains 0.002%-0.005% aluminum mass fraction, can obviously increase the brightness of the zinc layer, and prevent the zinc solution surface oxidation caused by excessive zinc ash.
Galvanized wire coating is galvanized, aluminum plated, coated with nylon or plastic, etc. Zinc is divided into thin coating of steel wire after plating and thick coating of galvanized steel wire after drawing. The mechanical properties of thick coating are reduced compared with smooth steel wire rope, which should be used in severe corrosion environment. It is more resistant to corrosion, wear and heat than galvanized wire rope, using the first plating and then drawing method of production. Coated nylon or plastic wire rope is divided into two kinds of coated rope and coated stock after the rope.
- 2, galvanized silk mesh forming sheet storage ground should be flat, according to the symbolic needs of regular accumulation, height should not exceed 2M, and away from heat source, avoid exposure.
- 5, when the terrain is limited, the barbed wire barbed wire protective net before and after can not be set continuously, this is the end of the barbed wire protective net, and handle the end of the sealing.
- At present, some manufacturers also use the process of sandblasting equipment for wire pretreatment, sandblasting process is carried out in the sandblasting room, but in the process of sandblasting, dust will permeate the whole sandblasting room, produce a lot of dust that is not easy to collect, and if the dust will be discharged at will.
- Reverse twisting of the barbed rope: first wrap the barbed wire around the main wire (that is, a single piece of iron wire) and then add an iron wire and twist together to form a double strand of barbed rope.
- 1. The center line of the barbed rope protective net is set within 20 to 50 cm of the road land boundary.
- The form of installation: in the top and the cage tied together at least should be like the stone cage net that is closely combined not easy to use bad. If the local dressing is suitable, the stability of the structure can be increased. There are a lot of mesh edge method, if the stone cage net only hook in the cage edge and not compiled in the cage edge, even in relaxation.
- The utility of the hexagonal net in the playground is very superficial, in each city to build the playground, are less than the shadow of the hexagonal net. In the stadium around the installation of hexagonal nets, not only can improve the stadium group image, but also convenient city residents to carry out a row of activities. Because the size of the plane or the surface of the object in the urban area is relatively small, many stadiums are built in the more prosperous and lively section, with the hexagonal net as a protective barrier, so it greatly reduces the spherical three-dimensional fly out of the field so as to affect the traffic order of bad things.
