What are the benefits of screen printing?
Today, I will introduce you to the advantages of several kinds of screen printing mesh products. You can choose the products that suit you according to your own situation. I hope this article can help you.
The surface of the nylon mesh is smooth, the ink permeability is good, and the ink with large viscosity and large particle size can be used, so that a fine printed pattern can be obtained; the mesh mesh with a fine mesh is used, which is suitable for the drawing pattern and dot printing of thin lines; High elasticity, suitable softness, good adaptability to substrates, suitable for printing on bumps and curved surfaces; good tensile strength, knot fastness, elasticity and abrasion resistance, long service life; acid resistance, chemicals and The organic solvent has good performance and is easy to regenerate, especially because it has strong resistance to alkali.
2. Polyester mesh
The tensile strength is small and the elasticity is strong. The single-wire mesh is suitable for high-precision printed matter such as printing integrated circuits, thick film semiconductors, scale plates, counting plates, etc.; tensile strength, structural strength, resilience and printing durability are good; Sufficient chemical resistance, especially strong acid resistance, strong organic solvent resistance, recyclable like nylon; low hygroscopicity, almost unaffected by humidity; heat resistance higher than nylon; affected by ultraviolet light Nylon should be small.
3. Stainless steel wire mesh
Stainless steel wire mesh has excellent plane stability and stable pattern size. It is suitable for printing high-precision circuit boards and other products; excellent ink passing performance; good alkali resistance and tensile strength; excellent chemical resistance; Strong, suitable for printing of hot melt printing materials (heating on the screen to melt the printing material). The disadvantage is that it is susceptible to external bending and damage, and the wire is slack due to pressure during the printing process, which affects the printing durability, is expensive, and has high cost.
4. Anti-static screen
The use of a synthetic woven fabric such as nylon or polyester is easy to carry static electricity, which is a big disadvantage. Although there are a variety of methods to prevent charging, they are not perfect, especially when drying, some substrates cannot completely remove static electricity. As shown in Figure 2-4, the anti-static screen is used to make the horizontal wire conductive. The core contains carbon filaments, which is very effective in eliminating static electricity.
