Paint meaning:
paint or coating. Paint is a chemical mixture that can be firmly coated on surfaces for protection, decoration, marking and other special purposes. Coating Technology, a relatively authoritative book in the Chinese coating industry, is defined as follows: "Coating is a kind of material, which can be coated on the surface of objects with different construction techniques to form solid film with firm adhesion, certain strength and continuity. The film formed in this way is known as coating film, also known as paint film or coating."
Coatings are generally composed of film forming materials, fillers (fillers), solvents, additives and other four parts. According to the performance requirements sometimes the composition will be slightly changed, such as varnish without makeup filler, powder coating can be no solvent.
Belongs to organic chemical polymer materials, the formation of the film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a kind of multi-functional engineering materials, which is an important industry in the chemical industry.

Paint function:
Protection function
Anti-corrosion, waterproof, oil proof, chemical resistance, light resistance, temperature resistance, etc. Objects exposed to the atmosphere, oxygen, water and other erosion, resulting in metal corrosion, wood decay, cement weathering and other damage phenomena. Coating on the surface of objects, forming a protective film, can prevent or delay the occurrence and development of these destructive phenomena, so that the service life of various materials. Therefore, the protective effect is a main role of paint.

Decorative function
Color, shine, pattern, smoothness, etc. Different materials of objects coated with paint, can get colorful, colorful appearance, play a role in beautifying human living environment, human material life and spiritual life to make a contribution that can not be ignored.

Other functions
Marking, antifouling, insulation, etc. For modern coatings, this role and the first two roles more and more show its importance. Some modern coating varieties can provide a variety of different special functions, such as: electrical insulation, conduction, shielding electromagnetic wave, anti-static generation and other effects; Anti-mildew, bactericidal, insecticidal, anti-marine biological adhesion and other biochemical effects; High temperature resistance, heat preservation, mild temperature marking, prevent burning, ablative heat insulation and other thermal energy functions; Reflecting light, emitting light, absorbing and reflecting infrared ray, absorbing solar energy, shielding ray, marking color and other optical properties; Anti-skid, self-lubrication, anti-splashes and other mechanical properties; There are anti-noise, vibration, disinfection, anti-condensation, anti-icing and other different effects. With the development of national economy and the progress of science and technology, paint will provide and play a variety of new special functions in more aspects.
