1. Tension strength refers to the ability to resist damage when the tensile force, with large tensile strength, which can be made into a high tension network version. Tension is made in N/cm. In addition, the strength change of the silk screen after moisture absorption should be small.
2. Small elongation of fracture
The elongation is the elongation of the mesh fracture as a percentage. The elongation is large and the planar stability is poor, but the silk print also requires the mesh to have sufficient elasticity at a certain tension such as 3%. So the elongation can not be zero, but small.
High tension, low elongation mesh, is a high (elastic) mold mesh, which is crucial to ensure printing accuracy.
3. Good return elasticity
The elastic force refers to the reply ability of the screen after stretching to a certain length (such as extending 3%), when releasing the external force, also known as the elongation response degree, expressed as a percentage. The bigger the value, the better. After the rebound, the imprint edge is clear.
4. Good stability of wet resistance and humidity change
The screen with high softening point can meet the requirements of hot printing screen, with small moisture absorption rate and the quality of printing can be stable.
5. Good passing performance of the ink
6. Good resistance to chemical drugs
Screen will encounter acid, reduction and organic solvents in the printing and printing process, which should have the most sufficient resistance.
