Carbon black, also known as carbon black, is an amorphous carbon. Light, loose and very fine black powder with a very large surface area ranging from 10~3000m2/g. It is a carbonaceous material (coal, natural gas, heavy oil, fuel oil, etc.) that undergoes incomplete combustion or thermal decomposition under insufficient air conditions. And the product. The proportion is 1.8-2.1. 　　 The one made from natural gas is called "gas black", the one made from oil is called "lamp black", and the one made from acetylene is called "acetylene black".

Pearlescent powder is composed of several thin layers of metal oxides coated with mica. Changing the thin metal oxide layer can produce different pearlescent effects. Compared with other pigments, the pearlescent powder pigment has an incomparable effect with its unique soft pearl luster. The special surface structure, high refractive index and good transparency enable it to create the same effect as pearl luster in a transparent medium.

Aluminum silver paste, English name: Aluminiumpaste alias: aluminum powder paste, flash paste, silver paste. Its main components are snow flake aluminum particles and petroleum solvent, which are paste-like. Its characteristics are that the surface of the aluminum sheet is smooth and flat, the particle size distribution is concentrated, the shape is regular, and it has excellent light reflection ability and metallic luster. It is mixed with transparent color pigments. The paint film has obvious "different color effect" and the decorative effect is very gorgeous Beautiful.

Aluminum silver paste is widely used in automotive paint, motorcycle paint, bicycle paint, plastic paint, architectural coatings, inks, mobile phone shells and keys, electromechanical shells, electrical shells, metal paints, and many other fields, but it is insoluble in water-based paints and silver pastes. Is solvent-based

The cross-section of pearlescent pigments has a physical structure similar to pearls; the core is mica with low optical refractive index, and the outer layer is wrapped with metal oxides with high refractive index, such as titanium dioxide or iron oxide. Under ideal conditions, the pearlescent pigment is evenly dispersed in the coating and forms a multi-layer distribution parallel to the surface of the substance. Like in pearls, the incident light will be reflected through multiple reflections, and interference will reflect the pearlescent effect.
