Surface tension is the attraction between liquid surface molecules. The surface tension of the ink affects the structure of the ink droplets on the print head and the way the ink wets the substrate. How to compare the surface tension of the ink volume? The tension of pure water is high, about 75 (dyne square centimeters). The surface tension of most organic solvents is very low, about 25 (dyne square centimeters). This is why the oily volume is even better. There is a solution called alcohol that can reduce the surface tension of aqueous inks. What is added to the water-based protective film to make it harmonize with the newly sprayed oil-based ink? Aqueous protective film is an aqueous protective film that contains both moisture and alcohol components. Alcohol has three functions: lowering the surface tension; making the water-based protective film compatible with the oily protective film; and making water-based protection faster.

Soft and hard dual mattresses: Soft and hard dual mattresses are made of brown or brown cotton plus springs. A soft and hard side that can adapt to different sleep requirements. You can also change the use of the surface according to their needs in the season, such as the winter cold, with a soft side to increase the degree of warmth; summer hot, ahard side vailable to switch over in order to cool faster and keep cooling in the comfort level.
