Color coated plate coating is how to form, color coated plate and what kind of function, these are all eager to know, today we mainly talk about the coating of color coated plate is how to form. Coatings are generally formed by film, and substances, pigments, fillers, are composed of five substances, such as solvents and additives, which play a very important role in the use of coatings.
The film-forming material has its own characteristics, and the film-forming material on the coating generally includes grease, natural resin, phenolic resin, asphalt, alkyd resin, amino resin, cellulose, perchloroethylene resin, vinyl resin, acrylic resin, polyester resin, epoxy resin, polyurethane resin, elemental organic compound, rubber, other (inorganic polymer, xylene resin, etc.).
Film-forming materials are generally divided into two categories. The first category does not change during the film-forming process, that is, the film-forming material has the same composition as the coating film. This film-forming material is referred to as unconverted film-forming material. They are thermoplastic, softened by heating and hardened after cooling. The other type means that the composition of the film is changed during the film forming process, that is, the film forming material is completely different from the original composition, and the latter is called the conversion film forming material.
The film-forming substance is hot oxygen or other substance. Under the effect of this substance, it is able to aggregate into an insoluble network polymer different from the original composition. The effect of the film-forming substance is to combine the pigment, filler and resin to form a uniform and fine substance on the substrate. After curing, the coating film constitutes the coating, which is the root of the coating and determines the adhesion of the coating to the substrate., coating physics, chemical and mechanical function.
Characteristic pigments of coloring pigments can generally be divided into two categories: coloring pigments and bulk pigments, also called fillers, which cannot constitute a film on their own. It is the main component of the coating about 70% to 80%. Coloring pigment is a solid powder, insoluble in water, insoluble in oil. Its main function is to appear color, and has the function of maintenance and decoration. The coloring pigment is combined with a binder. This is how the coating of the color coated board is formed. After reading the article, everyone should understand it.
