Sell a piece of leather! How can the motor look more beautiful?
The goods sell a piece of leather, and the motor is no exception. The direct contact of the customer is the most direct sensory surface of the motor. Therefore, different motor manufacturers will take necessary measures in these aspects, such as ensuring fans, hoods, fixing bolts, shaft extension sleeves, etc. It is both integrated and has the overall beauty of the finishing touch.
At present, it is more common to spray the motor main body before installing the fan and the hood, and at the same time, the hood to be installed is sprayed, and the fan and related fasteners are kept in the original color, so that the whole machine is assembled after the appearance. Or the dismantling process will give people a pleasant feeling.
Today's motor sales market, while competing for the performance of the motor, has extended to the industrial beauty of the motor. In the traditional sense of quality content, it has subconsciously increased the appearance, color and other details that do not affect the use of the elements, can be sure In fact, the consumption level of the motor is also advancing with the times. While using the motor, it is also to taste the quality of the product.
Summary of problems that are prone to occur in paint construction
(1) Sagging: There are many reasons for the sag when the paint is applied on the vertical surface, such as the paint is too thin, the paint film is too thick, the construction site temperature is too high, the paint itself is too dry, and the paint is heavy. Excessive pigment or poor adhesion, etc., will cause sag. In addition, the surface of the object to be coated is uneven or has water on the surface, too much paint on the surface, too short a brush, too soft, too much pressure on the spray gun, too close to the surface to be coated, etc., which will cause a hanging flow.
(2) Foaming: There are many reasons for foaming, such as water on the surface of the object to be coated, improper surface treatment, residual acid and alkali, and gas in the surface depression.
(3) Bite bottom: It means that the solvent in the top coat softens or even dissolves the primer paint film, which affects the adhesion of the primer. The reason for this phenomenon is that the bottom paint is not matched, or the primer is not dried, that is, the top coat is applied, so the paint should pay attention to the matching and drying conditions during construction.
(4) Pinhole: A small circle appears on the paint film, there are solid particles in the center, and the phenomenon of concave circles around it is called “pinhole.” The main reason for pinhole formation is the presence of air bubbles, for pigments. Poor wettability.
(5) Discoloration: The main reason is that after the film-forming objects and pigments are exposed to sunlight, aging and decomposition occur due to the action of ultraviolet light.
(6) Loss of light: improper paint formula, less resin content, too much thinner, water content in the pigment, not fine enough to grind, leaving mineral oil, alkali, wax or uneven surface on the surface of the coated object, in the cold Weather construction, condensation surface, different solvents.
(7) Crack: Due to the action of ultraviolet light and oxygen, the paint film loses its elasticity and cracks. The bottom and top coats are not matched. Due to the different composition of the paint, the expansion coefficient is inconsistent and cracks.
(8) Rusty: The surface of the steel is improperly treated, and there is residual rust. The chemical method removes rust, and the surface still has acid and alkali. The paint film is too thin and there are too many pinholes. Solution: Polish and repaint the original paint film.
(9) Hair flower: The pigments in the paint are different in size, the sinking is heavy, the wettability of the pigment is not good, and it is unstable after mixing with the paint, and the moisture absorption and oil absorption of the pigment are large.
(10) whitish: the construction site is too humid, the air contains a lot of water, causing the resin to precipitate in the paint, or the humidity on the construction site drops sharply, the water vapor condenses on the paint film, and the resin is precipitated to form a white, spray tool belt There is moisture, and the paint is applied during the construction, which will also cause the paint film to become white and the solvent and the diluent are not properly matched, and the paint film will be whitened.
(11) Pitting point: refers to the shrinkage of the surface of the paint film after construction, forming spotted spots, revealing the bottom layer, also known as "flower face, pitting or laughing mouth", most commonly in varnish, red lacquer, polyurethane paint, epoxy paint, etc. The main reason is that this kind of wetness to the surface of the coated object is poor, and a uniform film cannot be formed.
(12) Powdering: After the paint film is exposed, the powder layer appears on the surface, and the paint surface is touched by hand, that is, the powder is stuck on the hand, and the paint film is powdered. The cause of the pulverization of the paint film is mainly due to the effects of ultraviolet rays, water vapor, oxygen, marine climate, and chemicals.
(13) Shedding: The film peeled off and the pieces were peeled off and peeled off. The reason is: the primer is not properly selected, the primer gloss is too big, the top coat is not firmly attached, the surface treatment is not good, the bottom paint is improperly matched, and the adhesion is not strong, causing the whole piece to be removed.
