Screen Printing Mesh Features
1. Nylon screen features:
Nylon screen printing mesh is made of chemical synthetic fibers and belongs to the polyamide system. Nylon mesh has high strength, wear resistance, chemical resistance, water resistance and elasticity. Because of the uniform wire diameter and smooth surface, the ink passability is also excellent. The disadvantage is that the nylon mesh has a greater stretchability. The tension of the screen is reduced for a period of time after the stretcher, so that the screen printing plate is relaxed and the precision is lowered. Therefore, it is not suitable to print a circuit board or the like having a high dimensional accuracy.
2. Polyester mesh features:
Polyester mesh is also made of chemical synthetic fibers and belongs to the polyester system. Polyester mesh 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 the stretchability is small. The disadvantage is that the wear resistance is poor compared to nylon mesh. In addition to the advantages of nylon screen printing, polyester mesh is also suitable for printing printed circuit boards with high dimensional accuracy requirements.
3. Stainless steel wire mesh features;
Stainless steel wire mesh is made of stainless steel. The stainless steel wire mesh is characterized by good wear resistance, high strength and small stretchability; the fineness of the wire is good, the passing performance of the ink is good; the mechanical properties and chemical properties of the wire mesh are stable, and the dimensional accuracy is stable. The shortcoming is that the elasticity is poor 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.
