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
Safety is paramount when using a compressed air jack hammer. Operators require proper training and protective gear, including earplugs, safety glasses, and steel-toed boots, due to the loud noise and potential hazards associated with the tool's operation Operators require proper training and protective gear, including earplugs, safety glasses, and steel-toed boots, due to the loud noise and potential hazards associated with the tool's operation
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.

Post time: 28-06-22As we all know, the mechanism of resistance to atmospheric corrosion of zinc includes mechanical protection and electrochemical protection. Under the condition of atmospheric corrosion, there are ZnO, Zn(OH)2 and basic zinc carbonate protective film on the surface of zinc layer, which to a certain extent slows the corrosion of zinc. When this protective film (also known as white rust) is damaged, a new film will be formed.

Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.
The application of cold wire drawing is very wide today. What problems need to be paid attention to in the acceptance of cold wire drawing in galvanizing plant?
- Hard black galvanized iron wire is made of low carbon steel wire by wire drawing machine. Hard black galvanized iron wire is the first feature of high hardness, bright appearance. It is mainly used for welding clothes hanger, umbrella, metal mesh, basket, basket and other metal products. Soft black galvanized iron wire is made of low carbon steel wire after annealing and softening, and then cold drawing. Soft black galvanized iron wire is the first feature of good flexibility, slightly higher hardness, bright appearance. Mainly used for metal mesh weaving technology, welding net, process products of welding.
Post time: 15-11-22- Compared with electric galvanized iron wire, hot dip galvanized iron wire has higher zinc layer, better anti-corrosion performance, and is suitable for the more important anti-corrosion and anti-rust status.

Post time: 15-07-22Small and medium-sized cat cage, dog cage and fence are mostly pure wire welding, wire diameter is generally between 2-5mm. Of course, the larger the cage, the thicker the wire, because the larger cage has to withstand more force.

Post time: 09-01-23Large roll galvanized wire is like the literal meaning, is wrapped in a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc dissolves easily in acids and alkalis, so it is called a dissoluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.
- In sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, galvanized wire galvanized layer is easy to be corroded. The surface of galvanized wire galvanized layer uniformity and color of galvanized wire, good quality galvanized wire surface galvanized layer uniformity, zinc adhesion is good, and the color is white, no leakage plating and rust points.
Plastic-coated barbed rope is not only used but also beautiful, so it is used in a large number of highway sides, and other special places, so what are the colors of plastic-coated barbed rope? Where are the plastic-coated thorn ropes of no color respectively applied?
- The production and processing process of the blade thorn rope is complicated, which requires the cooperation of all departments, and the production cycle is relatively long. Whether galvanized rope or stainless steel rope, because of the relatively simple structure, the degree of mechanization in the production process is relatively high, so it is also a relatively big difference in price.
As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:
- Galvanized wire for welding is generally required to have a certain hardness, after acceptance of galvanized wire, feel is the first thing to do, in addition to the machine test, because the average user does not have testing equipment, on the machine trial is also a very inconvenient way to test. The diameter of electric galvanized wire is measured with a micrometer, and it is kept at about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no messy wire.
Due to the influence of production process or other factors, the zinc layer of galvanized wire products will be different to a certain extent, especially ordinary galvanized can not reach the beauty of electric galvanized, ordinary galvanized wire zinc layer is mainly for anticorrosion and corrosion prevention. Large volume galvanized wire products refers to the use of high quality low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes, some galvanized wire products are made of iron wire galvanized.
Galvanized wire drawing is more common in our life, galvanized wire drawing refers to the production of galvanized iron wire after a series of processes such as shell stripping. The production process of galvanized wire drawing is more complex, and a series of problems may occur if there is a slight mistake. When the wire factory is engaged in the production of galvanized wire drawing, it is necessary to remove all the tools and piles that hinder activities on the work site and equipment.
- 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.
