Dyne, also known as Corona T, dyne test pen, corona test pen, surface tension test pen, a small branch: 38,40,42,44 Set: 32,34,36,46,48,50,52, 54,56,58,59,61,63,65,67,69,71 舒曼达 because the scope of the pen: can accurately test the surface tension of the plastic film test whether the value of the pen, so that users clearly understand This film is suitable for printing a composite or aluminum vacuum, effectively control the quality and reduce the waste caused by defective material or schedule delays. Description: Corona T (dyne test pen) can accurately test the dyne value of the film surface or surface wetting tension, the foreign advanced technology production. Performance: Can accurately test the surface tension of plastic film whether the test pen value, so the user a clear understanding of whether this film is suitable for printing a composite or aluminum vacuum, effectively control the quality and reduce waste due to material failure caused by or schedule delays. British 舒曼达 due Pen Test Method: In industrial practice, the plastic surface energy (surface tension) was measured by testing the ink in accordance with DIN ISO 8296, a known ink brush on a different surface energy of the film on the proposed measure about 100mm long strip of ink and observed more than 90% of the ink edges within two seconds whether contraction and the formation of drops, if any, the low-level surface can change ink painted ink strip, perform the same observation, does not shrink and appear until the droplet, the ink surface of this test for the corresponding energy that is the surface energy of the film. This method can accurately measure the surface tension of the substrate, the front surface of the wet work force and determines whether the substrate surface elements in order to adjust the ink to meet the requirements, the coating, the desired viscosity to work. Something like 30 or 72 mN / m 21 test ink surface of the seed level (each difference 2mN / m). Dyne test pen (38mN / m) can be used as a corona treated surface can quickly test tools, but not suitable as well have been printed or coated surface of system testing. When the test pen corona treated surface to draw a line, if it is a continuous line, indicating that the surface energy of not less than 38mN / m, such as off not even a line, indicating that the surface energy of less than 38mN / m, inadequate treatment or even untreated, does not meet the requirements of the printing process. Surface tension, surface wet force dyne pen for accurate determination of printing inks and other materials in the surface of the bonding situation is very clear standards, but there are other factors that affect the viscosity, such as static electricity and a lot of additives. However, these factors do not often show in the test Shique, and even test results good but actually undesirable. This requires and raw material suppliers to discuss these technical issues. In general, the above dyne pen testing for them is not going to happen, and the surface value 38-41mN / m that can achieve the viscosity requirements. The surface tension at 37mN / m or less will cause many white pages (no print content), in 35mN / m or less viscosity on the bad. Dyne, also known as Corona T, dyne test pen, corona test pen, surface tension test leads Features: test accuracy, convenience, reduce waste, large capacity, liquid, long service life
