Using silk, silk or synthetic fiber and other raw materials woven, the surface has a uniform and stable ventilation holes, with screening and filtration of industrial fabrics. The mesh of the mesh is customary. The specifications of the screen are often expressed in terms of the number of holes per unit length (mesh), and the width of each hole. China’s national standard is expressed in terms of the number of holes per centimeter, such as 20 holes / cm. Screen according to the raw materials used into silk screen, wire mesh and synthetic fiber mesh three categories. Silk screen According to the specifications of the use of different fineness of the silk with the whole hank yarn organization, semi-hank yarn organization or plain weave woven, woven and mesh cloth similar. When the number of small mesh with a full hank organization, the purpose of a number of hours, with semi-hatching or plain weave. Silk screen specifications are 4 to 62 holes / cm, mostly for the food industry screening, but also for the grinding wheel Shibao factory selection of different thickness of sand. Metal mesh with brass wire, phosphor copper wire, stainless steel wire as raw materials woven into. The thickness of the wire is 0.4 to 0.025 mm. Mostly with plain weave or twill weave. Metal mesh hole clear and correct, flat surface flat, with high temperature, wear and other characteristics, stainless steel screen can also be resistant to corrosion. Therefore, metal screens are used for powder screening and oil filtration. Synthetic fiber mesh with nylon or polyester filament and brown silk two. Filament with 15 to 30 denier monofilament, screen mesh surface smooth, is conducive to filtration. Fabrics can be used with full hank, square and plain, etc., specifications are 19 to 104 holes / cm. Used for printing silk mesh, integrated circuit printed circuit board made, can also be used to filter the tube tube phosphor and magnetic particles such as magnetic particles. Brown silk screen with thick nylon yarn as raw material, diameter 0.55 ~ 0.1 mm, the fabric is mostly plain weave structure, for mineral processing, filter pulp, conveyor belt and so on. Synthetic fiber mesh with no rust, corrosion resistance and other characteristics, can replace part of the metal mesh.
