Just like the yellow color of the safety helmet. What's the name of yellow paint?
Paint as viscous, oily paint, flammable under dry conditions, insoluble in water, slightly soluble in fat, soluble in alcohol, aldehyde, ether, benzene, alkane, soluble in gasoline, kerosene, diesel oil.Regardless of the variety or shape of the paint, it is composed of three basic substances: film-forming material, secondary film forming material and auxiliary film forming material:Film material: also known as binder, film-forming material for most organic polymers such as natural resin (rosin, paint), paint (tung oil, linseed oil, soybean oil, fish oil, etc.), such as synthetic resin mix after high temperature reaction, also paint inorganic composition (such as inorganic zinc rich paint). A variety of film-forming substances according to national standards, a total of xxx. It is the main part of the paint, determines the performance of the film. If there is no film forming material, pure paint and auxiliary material can not form paint film.
Coating usually consists of four parts: film forming material, filler (pigment, filler), solvent and auxiliary agent. Depending on the performance requirements, sometimes the ingredients change slightly, such as varnish without pigments and fillers, and no solvent in the powder coating.Belongs to the organic chemical polymer material, the coating film formed belongs to the high polymer compound type. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a versatile engineering material and an important industry in the chemical industry.
Paint is a kind of chemical mixture coating that can firmly cover the surface of an object and protect, decorate, mark and other special uses. China paint industry authoritative "coating technology" is a Book of this definition: "coating is a kind of material, this material can be used in different construction process of coating the surface of objects, forming solid, solid film having certain adhesion strength, continuous. The film thus formed is commonly referred to as a coating film, also known as a paint film or coating."
Secondary film-forming substances include various pigments, constitutions, pigments, and rustproof pigments. The pigment provides color and hiding power for the paint film, improves the protective performance and decorative effect of the paint, and the paint with good weatherability can improve the service life of the paint. The pigment can increase the film thickness, using its own "flake, needle like structure, the performance of" pigment accumulation overlap, forming ichthyosifo film, improve the service life of the film, improve the waterproof and antirust effect. Antirust pigment through its own physical and chemical anti rust role, to prevent the object surface was atmospheric and chemical corrosion, metal surface corrosion.
Auxiliary film forming material: various additives, solvents, and various additives play a very important role in the production process, storage process, application process, and the formation process of paint film. Although the amount used is very small, it has a great influence on the properties of the film. Even without the film such as: dry, caking, bottom crust.Water paint need more additives to meet production, construction, storage and formation of paint film. The level of paint additives also represents the level of national paint. Solvent, also known as "dispersing medium" (including various organic solvents, water), is mainly diluted into film material to form viscous liquid, so as to facilitate production and construction. A mixture of film forming base material and dispersing medium is often called paint material.
