Are the ink used in printing machines flammable?
Including pigments and dyes, pigments, organic pigments and inorganic pigments, the bright color, strong coloring, dry time is short, so is widely used in inks, such as azo, phthalocyanine pigments; the latter light resistance, heat resistance, solvent resistance, good hiding power, such as titanium white, cadmium red, green, blue and chrome. Pigments are colored and not dissolved. They are the most commonly used pigments in printing ink. Dyes used in the preparation of a solution, in the state of color, the effect is not as good as pigment. Pigment can give ink with different color and color concentration, and make ink have a certain degree of viscosity and dryness.
One of the main components is ink, medium dispersing pigment and auxiliary material, is composed of a small amount of natural resin, synthetic resin, rubber, cellulose derivatives were dissolved in solvent to prepare or drying oil. There is a certain liquidity, so that the ink after printing to form a uniform thin layer, dried after the formation of a certain strength of the film, and the pigment plays a protective role, so that it is difficult to fall off.
