Screen printing machine | silk screen frame material physical properties, main index

Common physical performance index of the frame material is what?
     Silk screen printing are the most common use of net frame aluminum box, there are wooden screen frame, steel net box.The main physical performance index of this several kinds of screen frame has the following several aspects:
    (1) elastic coefficient, measured in newtons/cm.Woodiness material elastic coefficient of 0.12 x 107 n/cm, aluminum material
0.75 x 107 Newton/cm, steel material elastic coefficient of 2.1 x 107 Newton/cm.
     (2) the moment of inertia, the unit with the cm4 said.When the net frame material cross section shape is hollow rectangle (frame size is 5 * 4 cm, wall thickness is 2.5 mm), aluminum moment of inertia moment of inertia and steel material is 15.088 cm4, wooden screen frame section 41.667 cm4 shape.
     (3) density, the unit in g/cm3 (g/cm3) said.Woodiness material density is 0.9 g/cm3, steel qualitative material density is 7.8 g/cm3, aluminum material density is 2.7 g/cm3.
     (4) thermal expansion coefficient (105 / oC).Aluminum material thermal expansion coefficient of 2.4 x 105 / oC, steel qualitative material thermal expansion coefficient of 1.2 x 105 / oC, woodiness material thermal expansion coefficient of 3.0 x 105 / oC.

What are the main property index that are made of silk screen?
That is commonly used in screen printing screen have tulle, stainless steel wire mesh, nylon mesh, polyester silk net.The main characteristics of all kinds of silk screen has the following several aspects.
     (1) the tensile strength/g/d/diameter (g) silk network are 3.7 to 4.1 g/d, nylon network are 4.5 to 5.8 g/d, 4.3 5.5 g/d polyester yarn network, stainless steel wire mesh is 1.5 g/d.
    (2) the dry and wet strength ratio (%) of silk network are 92 ~ 100%, nylon network to 89 ~ 90%, and 100% polyester yarn network, stainless steel wire mesh is 100%.
   (3) nodules intensity of g/d/diameter (g) silk network are 2.9 g/d, nylon network are 4.5 to 5.4 g/d, 3.4 4.4 g/d polyester yarn network.
   (4) tensile elongation (%) of silk network 8 ~ 22%, nylon network 26 ~ 32%, 16 ~ 30% polyester yarn network, stainless steel wire mesh is 38%.
5. Dry wet elongation ratio (%) tulle 120 ~ 134%, nylon network to 115 ~ 122%, and 100% polyester yarn network, stainless steel wire mesh is 100%.
6 stretching response rates (% to 3% for calculation) silk network 80, aluminum moment of inertia moment of inertia and steel material is 15.088 cm4, wooden screen frame cross-section shape into a solid rectangle (5 * 4 cm), moment of inertia is 41.667 cm4
All landowners density, unit expressed in g/cm3.Woodiness material density is 0.9 g/cm3, steel qualitative material density is 7.8 g/cm3, aluminum material density is 2.7 g/cm3.
Today thermal expansion coefficient (10 l/oC).Aluminum material thermal expansion coefficient of 10 l / 2.4 oC, steel qualitative material thermal expansion coefficient of 10 l / 1.2 oC, woodiness material thermal expansion coefficient of 10 l / 3.1 oC.
