What Is Wire Mesh?
Screen is a woven fabric used as a support for screen printing plates, commonly known as silk screen, screen, screen, screen and so on. The screens commonly used for screen printing are natural screens, synthetic screens, metal screens, and special screens. The performance numbers of the screen, such as material, mesh number, opening degree, and aperture ratio, have a great impact on the transfer of screen printing inks. According to different originals, selecting the appropriate screen is to obtain high-quality screen printing replicas. premise. [1]

- The application fields of wire mesh are all over industry, agriculture, technology and national defense. From high-tech, high-tech industries, to food, clothing, housing, cultural life, synchronized development with the national economy, and related to the national economy and people's livelihood. China is the largest wire mesh producer in the world, and our wire mesh production base is Anping, Hebei.
- Wire mesh is a large classification of a class of silk fabrics, also known as
- China's annual imported silk screen volume has reached more than 1 million meters, and the main imported products are polyester screen and nylon screen above 270 mesh. High-density screens with high technical content, high-strength low-extension screens, anti-static screens, calendering and other special treatment screens and polyester high-mesh screens need to be imported.
- Domestic polyester screens and nylon screens have very good sales, and polyester screens still have a small number of exports. However, there are too few types and specifications of domestic screens. High-quality, high-mesh, wide-screen screens need to be developed.
- Foreign countries have developed a new type of non-woven wire mesh, which overcomes the trouble of applying photosensitive tape at the junction of traditional screen warp and weft threads. Modern advanced ultra-fine graphic screen printing, fine-level screen printing, high-precision positioning screen printing, special ink quantitative screen printing and large color tone screen printing, etc., all have higher requirements on the screens used: such as high strength , Low elongation variability, repeatability, consistency, long service life, etc .; such as high-tech products such as printed electronic micro-components, integrated circuits, multilayer printed circuits, fluorescent digital displays, aerospace instrument panel displays, etc. Some screen printing require antistatic, metallization, physical, chemical treatment or special materials.
- The precision of printed circuit boards and electronic components is obvious, and the accuracy of dimensional position is very high. In addition to the polyester, polyamide and stainless steel in the past, there are net yarns with high tensile polyester as the core and polyamide as the core cover. It is made of polypropylene fiber with 330 mesh, long diameter of 23m, and interlacing of 36m. It can obtain high tension. It is truly an epoch-making silk screen. In addition, in order to meet the requirements of precision, the above-mentioned screens are subjected to various processes such as plasma treatment, metal evaporation, and polishing.
