Introduction to the types and applications of stainless steel screen weaving methods
Stainless steel screen is also known as stainless steel wire mesh, stainless steel filter mesh, stainless steel woven mesh, stainless steel mesh.
Stainless steel screen mesh weaving methods: plain weave, twill weave, dense weave, mat mesh twill weave, double wire Dutch weave, five-harness weave.
1. Plain weave: Each warp wire crosses up and down each weft wire, the diameter wire is the same thickness as the weft wire, and the warp wire and weft wire are at a 90-degree angle.
2. Twill weave: A weaving method in which each warp wire crosses above and below every two weft wires, and each weft wire crosses above and below every two diameter wires.
3. Close-grain weaving: The warp and weft wires have different diameters and mesh numbers. They are characterized by sparse warp and dense weft, thick warp and thin weft. The length direction is warp threads, and the width direction is weft threads. Dense mesh is divided into plain weave and twill weave.
4. Mat-type mesh twill weave: a weaving method in which each diameter wire passes above and below every two weft wires crosswise, and each weft wire crosses above and below every two diameter wires.
5. Double wire Dutch weave: This weave is very similar to the twill Dutch weave. There are two weft threads that can overlap closely with the warp threads. This kind of silk cloth is mostly used for micron level filtration.
6. Five-harness weaving: In this kind of weaving, the warp and weft wires are not single wires but several separate wires. This weave is based on twill weave to provide a stronger and more powerful stainless steel wire cloth.
Stainless steel screen uses: Used in mining, petroleum, chemical industry, food, medicine, machinery manufacturing and other industries. Steel wires that are resistant to corrosion by weakly corrosive media such as air, steam, and water and chemically corrosive media such as acids, alkali, and salts are also called stainless acid-resistant steel wires. In practical applications, steel wires that are resistant to corrosion by weakly corrosive media are often called stainless steel wires, while steels that are resistant to chemical media are called acid-resistant steel wires. Due to the difference in chemical composition between the two, the former is not necessarily resistant to corrosion by chemical media, while the latter is generally stainless. The corrosion resistance of stainless steel wire depends on the alloying elements contained in the wire. Chromium is the basic element that makes stainless steel wire corrosion resistant. When the chromium content in the steel reaches about 12%, chromium interacts with the oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the surface of the steel. ), which can prevent further corrosion of the steel wire matrix. In addition to chromium, commonly used alloy elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. to meet the requirements for the structure and performance of stainless steel wires for various purposes.
