Shandong Rigang Supply Chain Management Co.,Ltd.The material of the metal woven mesh filter is made of metal wire woven mesh. The materials include carbon steel wire, stainless steel wire, aluminum wire, copper wire, etc. According to different weaving methods, the metal woven mesh is divided into two types: square hole mesh and dense pattern mesh. types. Dense netting can be divided into smooth grain and reverse grain. The square mesh woven by ordinary methods is generally used for coarse-effect filters; the dense mesh woven by inverted weave has high precision, good filtering effect, and high strength, but the porosity is small and the fluid resistance is relatively large.

The mesh number of metal braid is the number of holes, which is the number of holes per square inch. The larger the mesh number, the smaller the aperture. In general, the number of mesh × aperture (micron number) = 15000. For example, the aperture of a 400-mesh screen is about 38 microns; the aperture of a 500-mesh screen is about 30 microns. Due to the problem of opening ratio, that is, because of the difference in the thickness of the wire used in weaving the net, the standards of different countries are also different. Currently, there are three types of standards: the American standard, the British standard and the Japanese standard.
Metal wire screens are not allowed to have serious weaving defects, such as holes, half-cut wefts, serious dense channels, large cracks, severe curling of the mesh surface, out-of-tolerance mesh inclination, severe mechanical damage, and the interweaving firmness of warp and weft does not meet the requirements. wait. However, general weaving defects are allowed, such as single broken wire, nested weft, back nose, small loose thread, small jumper, wrong twist, slightly uneven mesh surface, slight curling, point-like oil stains, small debris woven into the mesh and mild wavy edge etc.
Wire mesh is a large classification of a type of silk fabric, also known as a screen. From the classification of materials, it can be divided into: barbed wire mesh, stainless steel wire mesh, copper wire mesh, rare metal mesh, etc. According to the classification of weaving method, it can be divided into: plain weave mesh. Twill weave mesh. From the classification of production process, it can be divided into: woven mesh, welded mesh, punched mesh, punched mesh. The functional classification is more extensive: filter screen, fence net, road fence net, railway fence net, mine screen, window screen, protective net, stainless steel mesh belt, etc.
Woven mesh is also called filter mesh and screen mesh. Its application fields are all over industry, agriculture, and science and technology. Up to the cutting-edge technology, high-tech industries, down to basic necessities of life, cultural life, and the simultaneous development of the national economy, closely related to the national economy and the people's livelihood. Mainly used in: aviation, aerospace, printing, printing and dyeing, electronics, mining, pharmaceuticals, grain, food processing, chemical industry. The four functions of the screen: sieve, filter, print, solid.
