What is the difference between the pigment and the dye?
Dye and pigment, it is soluble in water, alcohol, oil or other solvents and other liquids in the color of the material. Dye solution can penetrate the wood, and wood composition (cellulose, lignin and hemicellulose) complex physical and chemical reactions, can make the wood color and not to blur the texture of wood, can make wood dyed and fast s color
Pigment is a fine powdery colored material, generally insoluble in water, oil and solvent, but can be evenly dispersed in them. Pigment is the secondary film forming material of paint, in the wood decoration process modulation primer, putty and wood coloring, but also often use the pigment. Opaque paint due to the pigment, the coating has some color and hiding power. While the pigment can also enhance the durability of the coating, weather resistance, wear resistance and so on.
It is not possible to discolor water as a standard to distinguish between dyes and pigments. The difference is that the coloring of the object is different and the dye can penetrate into the interior of the object, such as inside the fiber, and the pigment can only act on the surface of the object, such as the surface of the fabric.
General: 1, the dye is soluble in water and the pigment is insoluble in water. 2, the dye involved in the chemical reaction pigment is not involved.
Pigments and dyes, pigments, organic pigments and inorganic pigments, the former bright colors, strong coloring, widely used in the ink, such as azo, phthalocyanine pigments; the latter light resistance, heat resistance, solvent resistance, Concealment are better, such as titanium dioxide, cadmium red, chrome green, ultramarine and so on. Pigments are colored in a particulate matter and are not dissolved and are the most commonly used colorants in the ink. The dye in the use of preparation into a solution, was molecular state coloring, the effect is not as pigment. The pigment can give the ink a different color and color density, and the ink has a certain degree of viscosity and dryness
