Mesh is the foundation of mesh printing. Choosing the right polyester mesh is an indispensable link. Since the scope of application of polyester mesh is very wide, the factors related to it are various. When selecting a mesh, it is necessary to select a suitable mesh according to the specific conditions and printing requirements.
1) Select the mesh according to the type of substrate, and select according to the fiber accumulation, paper products, glass, ceramics, metal, plastic, wood products, electronic products and so on.
2) The polyester mesh is selected according to the nature of the ink. Different inks have different adaptation characteristics. Therefore, when selecting the Polyester mesh, it is necessary to consider the drying time and color vividness of the ink, and the ink absorption capacity of the substrate.
3) When selecting the mesh according to the mesh material and performance, the mesh itself should be considered, and the corresponding mesh should be selected according to different performance.
4) Screen is selected according to printing standards, and the printing speed, printing pressure, printing plate endurance, and substrate absorption capacity should be considered when selecting.
Nylon mesh is made of chemical synthetic fibers.It has high strength, abrasion resistance, chemical resistance, water resistance, and elasticity.It has a uniform silk diameter and a smooth surface. Excellent. The disadvantage is that the stretchability of nylon mesh is large. In a period of time after the mesh is stretched, the tension is reduced to relax the mesh printing plate and reduce the accuracy. Therefore, it is not suitable to print circuit boards with high dimensional accuracy.
Polyester mesh is also made of chemical synthetic fibers.It has the advantages of solvent resistance, high temperature resistance, water resistance, and chemical resistance.When the polyester mesh is subjected to external pressure, its physical properties are stable and stretched. It is small and its disadvantage is that it has poor wear resistance compared with nylon mesh. In addition to the advantages of nylon mesh printing, polyester mesh are also suitable for printing printed circuit boards that require high dimensional accuracy.
Stainless steel wire mesh is made of stainless steel material. It is characterized by good abrasion resistance, high strength and small stretchability; due to the fine wire diameter, the ink passing performance is stable and the dimensional accuracy is stable. The disadvantage is that the flexibility is not good and the price is more expensive. After the screen is stretched, it cannot be restored. Stainless steel wire mesh is suitable for high-precision printing such as circuit boards and integrated circuits.
