What is color paste
Color paste is composed of pigment particles, wetting agents, and dispersants dispersed together and evenly distributed in a solvent. Water-based color pastes use water as the medium, and oil-based color pastes use alcohols, esters, and other JI solvents! Water-based color paste is just like the soy milk that we often eat in our lives. After the soybeans are ground into fine particles, the particles are evenly stored in the water. It looks like an emulsion-like substance! The pigment particles in the water-based color paste are coated with surfactants such as wetting agents and dispersants and then evenly dispersed in the water
What is sex sperm
Color essence refers to a type of pre-dispersed products of metal complex dyes! Its function is to dye! Oil-based color essence is a metal complex dye that is soluble in aromatic solvents, esters, styrene, methyl methacrylate and other solvents (almost insoluble in water). Water-based colorants are metal complex dyes that are soluble in water or alcohol. Color essence exists in a molecular state in the solution and can be used for coloring! Just like sugar dissolves in water, it exists in the water as sugar molecules!
The difference between water-based color paste and color essence
The coloring mechanism is different
1. The color essence is dyed by combining the molecular form with the dyed substance through a chemical reaction!
2. The color paste is in a granular state, with extremely fine particles evenly distributed on the surface of the dyed material. It relies on the matching adhesive to adhere to the surface of the dyed material with fastness.
Different coloring effects
1. The color essence is dyed in a molecular form, so it has good transparency, such as wood paint, metal paint coloring, etc.!
2. Color paste exists in the form of extremely fine pigment particles and has strong hiding power. Therefore, water-based printing paint paste is required to print patterns and text on fabrics such as clothing.
There is a huge gap in environmental protection levels
1. There is a metal complex structure in the color essence, and the presence of heavy metals is unavoidable. In some products that directly contact the skin, it is not recommended to use metal complex color essence as a dye!
2. The color paste uses pigment particles as the coloring body. As long as safe pigments and additives are used, the environmental protection of the water-based color paste is guaranteed. </p
