Test Method For The Interweaving Firmness Of Metal Mesh Warp And Weft Threads

Cut a piece of 100mm × A 100 mm mesh block is subjected to a weight of 100 g on the diagonal of a square mesh block. Under a gravity of 1 N, the diagonal of the mesh block is stretched, with a specified extension range, such as (154-167) mm. If the diagonal length of the tested mesh block is between (154-167) mm, it is considered qualified.

According to different metal mesh specifications, we can change the magnitude of the diagonal force on the mesh block, and specify the length range of the diagonal under a fixed tension value.

Test method: Place a square mesh block of 100mm × Hang a 100mm corner on the wall and a 100g weight diagonally. When hanging heavy objects, gently hang them on the corner of the net. When releasing the heavy object with your hands, slowly measure the length of the stretched diagonal when the object is stationary.

The firmness of wire mesh weaving can be expressed by the torque resistance at the interweaving point. The theoretical torque resistance can be calculated. Calculate the total fluctuation of torque resistance based on the fluctuation of warp and weft density and bending moment resistance. For a specific specification of woven mesh, developing a scientifically reasonable range of diagonal length is a topic that we need to study in the future.
