油墨使用知识十问十答（The use of ink in a knowledge ten）

油墨使用知识十问十答（The use of ink in a knowledge ten） The use of ink in a knowledge ten 2-15 HC screen printing network 1. What is the composition of solvent ink? Whats the function of each? Answer: 1: resin binders, mainly side.this, determine ink smooth, hardness, weatherability, moisture resistance and other properties. The pigment: determine ink fineness, weather resistance and solvent resistance, resistance to drugs and other properties, as well as whether containing heavy metals. The additives: improve the printability of ink. The solvent used to adjust viscosity, conditioning speed, increase and substrate adhesion, dissolved resin links and additives, pigment dispersion. 2, what are the five variables? Answer: scraper hardness, mesh distance, printing speed, scraping pressure, ink suitability. 3, before the use of ink has not stirred, add diluent, right? Why? Answer: not before mixing with thinner is wrong, because the ink in the external force (such as mixing), its viscosity decreases, thixotropic properties of dilute, so any ink cans must be thoroughly agitated after adjusting the viscosity. 4. What is the solvent in the solvent ink? Answer: the dissolution of the resin ink made of adhesive material. The dispersion of pigments and additives dissolved in the ink, improve printability. The solubility and swelling of substrate, improve the ink and substrate adhesion. The adjustment of viscosity, improve the printability of ink. The regulation of drying speed, meet the environmental requirements of screen printing. 5, if the ink quality is no problem, then in the silk screen process, there are bubbles generated by what causes? How to solve? Answer: Causes and solutions: the ink viscosity is wrong, will dilute. The squeegee speed, the network distance, due to screen off the substrate too fast out of the bubble. By using the wrong solvent, and the miscibility of ink, so we must use special solvent ink. The use of quick drying solvents in high temperature and humidity con
