Material classification and product use of mesh die-cutting productsIssuing time:2025-03-02 14:10 Mesh count is a unit that represents the density of woven mesh (the number of mesh holes contained between a 1-inch length mesh) 9759彩票集团2-wire diameter The diameter of the silk thread is the thickness of the silk thread. Represented as TD in the figure 9759彩票集团3 thickness Thickness is the measured value of the thickness of the mesh when it is in a tension-free and static state 4 openings 9759彩票集团Openings are a method used to indicate the size of the mesh holes. The opening is determined by the thickness of the silk thread and the mesh size. 5 porosity rate Openness rate refers to the percentage of mesh that occupies the area of gaps per unit area. The larger the percentage, the higher the porosity of the network. 9759彩票集团6 acoustic resistivity Sound resistance=sound pressure/particle velocity. It is the most important parameter related to sound. The smaller the value, the smaller the sound barrier. Material classification of mesh die-cutting products 9759彩票集团Polyester PET 9759彩票集团Features: Low shrinkage, high strength, acid resistant and environmentally friendly 9759彩票集团Not absorbing water on its own After encountering water, the aperture will not change 9759彩票集团Acoustic performance and stability Nylon PA 9759彩票集团Feature: High Elongation Has water absorption properties After encountering water, the aperture will change, resulting in a change in acoustic impedance Unstable acoustic performance 9759彩票集团Classification of uses of mesh die-cutting products Characteristics of dustproof net: 9759彩票集团Accurate and consistent mesh size smooth surface 9759彩票集团Accurate filtering performance 9759彩票集团Dust proof level: IP5X Lighter and thinner Purpose: Mainly used for protection and dust prevention of computers, speakers, mobile phones, and various speakers. 9759彩票集团Excellent dust-proof performance, minimal ventilation, stable transmission loss, and product performance to meet customer needs to the maximum extent possible |
