What is Wire Mesh?
The metal wire woven net is made of different materials and different specifications of metal wire by the loom. Screen products with various uses. Among the numerous wire mesh products, the metal wire woven mesh has the largest classification of specifications and materials. The mesh size can be controlled from several hundred meshes to several meshes, the wire diameter range is 0.02-5mm, the width range is 100-3000mm, and the minimum micron level is 5-350 μ M. The material can be steel wire, stainless steel wire, copper wire, aluminum wire, etc. In this paper, we will describe the classification and characteristics of different types of woven fabrics, to discuss how to choose the right metal woven fabrics.
What Are the Types of Metal Woven Mesh?
Woven mesh types are based on their typical application, Including decorative mesh, insect proof mesh, stainless steel mesh, shielding mesh, sintered mesh and metal welded mesh, as well as many other types. Each of these different types of materials will provide different space in the weaving process, and have different uses due to the different density provided by each material.
What are the characteristics and uses of all kinds of metal woven nets?
1) Decorative Mesh
The decorative mesh is composed of a metal bar or metal cable. According to the weaving form of the fabric, it is composed of various patterns of horizontal metal bar passing through the vertical metal cable. The materials used include stainless steel, high-strength corrosion-resistant chromium steel, aluminum wire, and other metals. There are also various other colors on the surface after special treatment of gold, silver, titanium, tin and other elements.
There are many kinds of decorative mesh, including metal mesh curtain, metal vertical curtain, metal curtain, copper curtain, vertical curtain, spiral metal mesh curtain, decorative metal mesh curtain, curtain metal mesh curtain, ceiling, ceiling metal mesh curtain.
It has a wide range of applications and remarkable decorative effects and has become a new favorite of mainstream architectural art. And can be processed into a unique color, these metal decorative nets with color, also, to retain the functional advantages of metal, and easy to maintain, its smooth appearance is easy to clean, better meet the designer's requirements for style and personality.
Metal decoration mesh is widely used in the fields of facade, partition, ceiling, sunshade, balcony and corridor, column surface decoration, rolling curtain, stairway and interior decoration of hotel, office, exhibition hall, shop, etc. it is mainly used for decoration of hotel, opera house, exhibition hall, airport station, office building, restaurant, and other places.
The characteristics of the decorative mesh are not limited by the size of space, easy to install, with lighting will produce a very mysterious effect, a strong sense of modern. It can be said that the structure is beautiful and durable. At the same time, it can also produce metal decorative net with copper or aluminum alloy as the raw material. The finished product can be the original color of metal, or it can be sprayed into ancient copper, brass, red copper jujube or other colors. The height can be specially made according to the needs.
2) Insect Proof Mesh
Insect proof mesh is a kind of net fabric that is made of polyethylene with anti-aging, anti-ultraviolet and other chemical additives as the main raw material, anti-aging, anti-ultraviolet, and other additives, and is drawn. Most of them are 30-40 mesh, with a width of 1-1.8m.
It has the characteristics of heat resistance, tensile strength, UV resistance, stain resistance, anti-aging, non-toxic and tasteless. It is mainly used to cover the doors and windows of the plastic arch shed and the greenhouse, cut off the ways of all kinds of insect pests entering into the spawning and reproduction, larva harm and poison transmission, and realize the pesticide-free cultivation of vegetables.
Therefore, for farmers, it can be used in vegetable cultivation, to achieve the effect of insect control and vegetable preservation.
3 ) Stainless Steel Mesh
The stainless steel mesh is made of 304, 304L, 316, 316L, 310, 310S and other metal wires. The surface is treated by electropolishing technology, and the surface is bright as a mirror. It has the characteristics of no rust, corrosion resistance, non-toxic, sanitary, environmental protection, heat resistance, acid resistance, corrosion resistance, wear resistance, etc.
Because of these characteristics, stainless steel mesh is widely used in mining, chemical, food, petroleum, medicine and other industries, hospitals, pasta, meat barbecue, flower baskets and fruit baskets for daily use are mainly stainless steel mesh. It can also be used for gas, liquid filtration, and other media separation.
4 ) Shielding Mesh
Shielding mesh is a kind of network used for electromagnetic/signal shielding. The densest mesh can be 200 mesh, and the largest mesh can be several centimeters. It has the characteristics of magnetism, wear-resistance, and sound insulation. It is often used as electronic/electromagnetic/signal shield for wall sound insulation, electronic display screen, etc.
5 ) Sintered metal mesh
The sintered metal mesh is a new type of filter material with high mechanical strength and overall rigid structure, which is made of multi-layer metal woven mesh by special laminated pressing and vacuum sintering technology.
The mesh of each layer of wire mesh is staggered to form a uniform and ideal filtering structure, which not only overcomes the shortcomings of low strength, poor rigidity, and unstable mesh shape of common wire mesh but also reasonably matches and designs the pore size, permeability and strength characteristics of the material.
So that it has excellent filtering accuracy, filtering impedance, mechanical strength and resistance The comprehensive properties of grinding, heat resistance and processability are superior to other types of filter materials such as sintered metal powder, ceramics, fiber, filter cloth, filter paper, etc.
Because the filtration mechanism of sintering screen is surface filtration and the mesh channel is smooth, it has excellent backwash regeneration performance and can be used repeatedly for a long time, especially suitable for continuous and automatic operation process, which is incomparable with any kind of filter material. The sintered mesh material is easy to be formed, processed and welded, and can be processed into various forms of filtering elements, such as round, cylindrical, conical, corrugated, etc.
It has high mechanical strength and compressive strength, good processing, welding and assembly performance, easy to use. At the same time, the accuracy is uniform and stable, all the filtering accuracy can achieve uniform filtering performance, and the mesh hole does not change in use. It can be used for filtration in - 200 ℃ ~ 600 ℃ temperature environment and acid-base environment.
The sintered screen is mainly used as dispersive cooling material in a high-temperature environment, gas distribution, liquid bed orifice material, high-precision, high-reliable high-temperature filter material, and high-pressure backwash filter.
6）Metal welded mesh
The welded metal mesh is a kind of metal mesh welded by human or machine. It is made of galvanized wire, stainless steel wire, steel bar, and iron wire.
The diameter of welded mesh reinforcement is 4-14mm, in which 0.5mm progressive diameter can be used. Considering the transportation conditions, the length and width of the welding network should not exceed 12m and 3.4m respectively.
The spacing of steel bars (or longitudinal bars) in the manufacturing direction of the welded mesh should be 100, 150, 200 mm, and the spacing of steel bars in the other direction is generally 100, 150, 200, 300 mm, sometimes up to 400 mm.
It is mainly used in the fields of birdcage, egg basket, passage fence, drainage channel, porch guard fence, rat-proof net, mechanical guard, livestock and plant fence, grid frame reinforced electric welding net Industrial and civil construction, highway, bridge, airport, wharf and breeding fence, various guardrails, etc.
The above is the classification of wire mesh and the characteristics and uses of various types of wire mesh. We can choose the appropriate wire mesh according to the specific use environment.
