What is the paint and what is the purpose of the car paint?

Coating is to treat the surface of the material to be protected according to certain standards, including surface treatment.

Construction protective layer (paint or other media), cathodic protection.

etc., in order to protect the surface from the influence of corrosive media and achieve aesthetic functions.

Painting is a series of processes such as phosphating (or grinding), surface painting (spraying), and drying of the surface of the workpiece.

Surface treatment. Paint process.

Coating is an important part of the surface manufacturing process of construction machinery products. Anti-rust and anti-corrosion coating quality is one of the important aspects of overall product quality. The appearance quality of the product not only reflects the protective and decorative properties of the product, but also is an important factor in the value of the product.

Coating is a systematic engineering, which includes the treatment of the surface of the coated object, the coating process and the drying of the three basic processes before coating, as well as the selection of appropriate coatings, the design of a reasonable coating system, the determination of good operating environmental conditions, and the important links such as quality, process management and technical economy. The anti-rust coating process of construction machinery can generally be divided into surface treatment process before coating and anti-rust primer coating process.

The role of the paint.

1.Protection: Protect metal, wood, stone and plastic and other objects from being eroded by light, rain, dew, hydrated media. Covering objects with paint is one of the most convenient and reliable ways to protect objects and extend their lifespan.

2.Decorative effect: Paint coating can make the object "clothed" with a beautiful coat, with brilliance, luster and smoothness, and the beautified environment and objects make people feel beautiful and comfortable.

3.Special function: After coating the object with special coating, the surface of the object can be made with the functions of fireproof, waterproof, antifouling, temperature indication, heat preservation, stealth, conduction, insecticide, sterilization, luminescence and reflection.

The function of the body painting.

Protective. Automobiles have a wide range of uses, a wide range of activities, and a complex operating environment, and are often eroded by moisture, microorganisms, ultraviolet rays and other acid and alkali gases, liquids, etc., and sometimes are damaged by grinding and scraping. If you apply paint to its surface, you can protect the car from damage and prolong its life. This is because the surface of the body is coated to isolate the basic materials of the parts from the atmospheric environment, which acts as a kind of "shielding" to prevent corrosion.

On the other hand, some coatings can also act as corrosion inhibition for metals, such as phosphating primers, which can react with metals with the help of the chemical composition inside the paint to passivate the metal surface.

decorative role. Modern cars are not only a practical means of transportation, but also a work of art. The color of the body matches the color of the interior of the car, harmonizes with the color of the environment, and adapts to people's preferences and sense of the times. Brilliant colors and beautiful lines are combined to form the plastic art of the car.

Special identification role.

The marking function of the paint is reflected by the color of the paint. Painting cars with different colors and patterns to distinguish cars for different purposes. For example, fire trucks are painted bright red; The postal car is painted olive green, and the font size and car number are white; The ambulance is white and marked with a red cross; The engineering vehicles are painted with yellow and black stripes, and the characters and car numbers are black.

In addition, the role of color in traffic signs such as signs, warnings, prohibitions, and directions is also very obvious.

Ordinary lacquer is the simplest, resins, pigments and additives. Ordinary paint is the most common automotive paint, characterized by low cost and simple process, but its gloss is not very good, the surface hardness is not high, and it is particularly easy to scratch. Therefore, it is rarely used in cars, and even if there are low-grade models, most of them are used in trucks and buses.

2. Metallic paint:

Metallic paint is on the basis of ordinary paint plus aluminum powder, so it looks bright after completion, the biggest feature of metallic paint is not only high brightness, but also its hardness is much higher than ordinary paint, and it is not easy to scrape it off with ordinary objects, so cars, especially high-end cars, basically use metallic paint.

3. Pearlescent paint:

Pearlescent paint uses mica instead of aluminum particles. In its lacquer base is added mica pigments coated with titanium dioxide and iron oxide. When light hits the mica particles, it first takes on the colors of titanium dioxide and iron oxide, and then complex refractions and interferences occur in the mica particles.

At the same time, mica itself has a special, transparent color. In this way, the reflected light has a sparkle like a pearl. In addition, titanium dioxide itself has a yellow color, which changes to light blue when viewed in squint, and has different colors when viewed from different angles.

Hello 1. Protection: all kinds of corrosion (such as acid rain corrosion), solar ultraviolet rays, to prevent rust on the body.

2. Decorative function: reflected in color, pattern and luster.

3. Logo function: special function of the car: police car, fire truck, fire truck, etc. 4, other general use: sealing, heat insulation, sound insulation.

Car painting is not only for aesthetics, but more importantly, to protect the car and prolong the service life of the car.

Although the value of cars is depreciating rapidly, car owners do not want the quality to decline rapidly. Normally, the process of producing the car to the owner's use is experienced by the wind blowing, sun, rain, dry and wet alternately, hot and cold alternately, etc., and the harsh environmental test is not provided, if there is no protection of the car coating, the car will rust and disintegrate in a short period of time, and the service life will be greatly reduced.

The automobile coating process can generally be divided into two parts: one is the surface treatment of the metal before painting, also known as pre-treatment technology; The second is the construction process of coating. Surface treatment mainly includes the removal of oil, dust, rust on the surface of the workpiece, and the removal of the old coating layer during repair operations to improve the surface condition of the workpiece.

This includes machining and chemical treatment of the workpiece surface, such as phosphating, oxidation and passivation, depending on the specific situation.

The purpose of car painting:

1. Protective.

Subjectively, the 90 car was made of steel, and if the car was not painted, you can imagine it. The life of the car is greatly reduced, so it is necessary to paint the car. Coating film can protect the car from corrosion, with the introduction of new materials on the market, the role of coating film protection is increasing, such as:

High scratch resistance, elasticity, stain resistance, etc.

2. Aesthetic effect.

From the beautiful appearance of the lacquer film、The beauty of the gorgeous soft、Colorful and diverse to follow the trend of the atmosphere。

From the 50s of the last century from a single color to the present. Automobile paint from plain paint, metallic paint, pearl paint has also been changed from different perspectives, so as to enhance the beauty of the car, the appearance of the beauty to give people a sense of beauty.

1. Coating refers to the process in which the coating is applied to the surface of the object, so as to form a protective or decorative or specific functional coating.

2. The engineering system involved in the coating engineer in order to realize the coating of the coating on the metal or non-metal surface.

3. Coating is also a general term for the production activities carried out by operators in the whole process of coating.

Automobile coating is a solid continuous film obtained by one-time application of coating, which is a thin layer of plastic coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation, decoration and other purposes. Coatings can be gaseous, liquid, or solid, and the type and state of the coating usually depends on the substrate to be sprayed.

Car modification is the modification of the performance or appearance of a vehicle. However, in the actual sense of automobile or vehicle modification, it generally refers to the modification of the engine.

The definition of automotive painting refers to the imposition of paint on top of a treated object. The process of drying and forming films.

Hello dear, painting is the process of applying paint or paint to the surface of an object with the purpose of protecting the object, increasing aesthetics, improving texture, increasing durability, etc. The main functions of the livery include:1

Corrosion and rust protection: Applying the right coating to the metal surface can prevent air, water, and chemicals, making it less susceptible to rust and corrosion. 2.

Beautify objects: Through painting, they can be matched to add color, shine and texture to the object, making it more attractive and aesthetically pleasing. 3.

Improved durability: Coatings can increase the hardness, abrasion resistance, and weather resistance of an object, making it more durable. 4.

Anti-fouling performance: The coating can reduce the adsorption capacity of the surface, making it less susceptible to pollution and dirt, and it is also convenient for cleaning and serving. 5.

Protecting the environment: Shielding coatings can be used to prevent the release of harmful substances from objects, such as special coatings used in food processing plants and hospitals to prevent the growth and spread of microorganisms. Paints are widely used in many industries, such as automotive manufacturing, construction, aerospace, machine building, and furniture manufacturing.

<> "Hello friends, painting refers to the act of coating a film on the surface of an object to achieve the purposes of anti-corrosion, fire prevention, beautification, concealment, and identification. There are many types of paints, and different formulations can be selected according to the needs, and the purpose of the coating is different from the paint required for the desired effect. For example, in automobile manufacturing, painting is to beautify the appearance of the body, increase the texture, maintain the color for a long time, and also to prevent corrosion and wear; In aircraft manufacturing, painting is to reduce air resistance, stabilize the flight family, make the aircraft more recognizable, and also to protect the aircraft from corrosion, high-altitude environment during flight, etc.

In short, painting plays a very important role in various fields. I hope mine can help you<>
