What are the main characteristics of silk screen printing materials?

Mesh screens commonly used in screen printing are nylon mesh, nylon mesh, polyester mesh, and stainless steel mesh. The main features of various screens are the following.

1 Tensile strength [g (g)/D (diameter)] gauze is 3.7-4.1 g (g)/D diameter), nylon gauze is 4.5-5.8 g (g)/D (diameter) ), Polyester mesh 4.3-5.5g (grams) / D (diameter), stainless steel mesh 1.5g (grams) / D (diameter).
2 Dry-wet strength ratio (%) The net weight is 92% to 100%, nylon mesh is 89% to 90%, polyester mesh is 100%, and stainless steel mesh is 100%.

3 Nodule Strength [g (grams)/D (diameter)] Netting is 2.9 g (grams)/D (diameter), nylon mesh is 4.5-5.4 g (g)/D (diameter), Polyester mesh is 3.4-4.4g (g)/D (diameter).
4 tensile elongation (%) 8-22% of netting, nylon screen 26-32%, polyester screen 16"30%, stainless steel screen 38%.
5 Dry-wet elongation ratio (%) A mesh thickness of 134% for nylon 120, 115" 122% for nylon mesh, 100% for polyester mesh, and 100% for stainless steel mesh.
6 Tensile recovery rate (%, calculated with 3% extension) The stencil net is 80-aluminum material moment of inertia and steel material has a 15.88-centimeter square of inertial moment, and the cross-section of the wooden net frame has a solid rectangle ( 5 x 4 cm), moment of inertia 41.667 cm 4th power.
7 Density in units of grams per cubic centimeter. The wood density is 0.9 g/cm3, the steel density is 7.8 g/cm3, and the aluminum density is 2.7 g/cm3.
8 Thermal expansion coefficient (10`/°C). The thermal expansion coefficient of the aluminum material is 2.410`/°C, the thermal expansion coefficient of the steel material is 1.2 10′/°C, and the thermal expansion coefficient of the wood material is 3.0 10′/°C.
