Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Introduction: red lead alkyd

painting, the rust, weld coating, welding spatter, oil stain, dust and other sundries of the parts to be painted shall be cleaned ② The quality of base surface cleaning and derusting is directly related to the quality of coating Therefore, the rust removal quality of the base surface of the coating process is divided into two levels ③ In order to ensure the coating quality, the following rust removal processes can be selected according to different needs a Sand blasting derusting is a kind of derusting method that uses the pressure of compressed air to continuously impact the surface of steel members with quartz sand or iron sand, clean up the rust, oil and other sundries on the steel surface, and expose the true color of metal steel This method has high efficiency and thorough rust removal It is an advanced rust removal process b Pickling is to dip the steel members to be coated into the acid tank and remove the oil and rust on the surface of the members with acid The efficiency of pickling process is also high and the rust removal is thorough However, after pickling, the components must be washed with hot water or clean water If there is residual acid, the components will be more severely rusted c Manual derusting is to remove the rust on the steel members by manually using some simple tools, such as scraper, grinding wheel, emery cloth, wire brush, etc This method has low efficiency, poor working conditions and incomplete rust removal 2 Primer coating: ① prepare red lead antirust paint, control the viscosity, consistency and thinness of the paint, and fully mix when cashing, so that the color and viscosity of the paint are uniform ② When the first layer of primer is applied, the direction of application shall be the same and the joints shall be neat ③ When painting, the principle of frequent touch and short brush shall be adopted to prevent the brush from falling due to too much paint ④ After the first painting, a certain time interval shall be maintained to prevent the second painting before the first painting is dry, which will make the paint liquid flow wrinkle and reduce the quality ⑤ After the first drying, brush the second time, and the direction of the second painting shall be perpendicular to the direction of the first painting, so as to make the film thickness uniform ⑥ At least 4-8 hours after the primer is applied, the surface drying can be achieved, and the top coat shall not be applied before the surface drying 3 Finish painting: ① the interval between primer and finish painting of steel structure is generally long Steel members shall be sent to the construction site for assembly after being coated with antirust paint, and the finishing coat shall be applied uniformly after assembly In this way, the steel structure surface needs to be cleaned before the finishing coat is applied, the welding flux of the installation weld shall be removed, and the components burnt or touched with the paint shall also be repainted in advance ② The top coat with the same color shall be selected for the preparation of the top coat, and the prepared diluents shall be suitable The top coat shall be fully stirred before use to keep the color uniform Its working viscosity and consistency shall ensure that there is no sagging and brush marks during painting ③ The finishing coat shall be continuously mixed during use, and the method and direction of application shall be the same as the above process ④ When the coating process adopts spraying construction, the nozzle diameter and spraying pressure shall be adjusted, the spray gun hose can be stretched to the operation area freely, and the air pressure of the air compressor shall be 0.4-0.7 n / mm2 ⑤ The distance between the spray nozzle and the coating shall be kept well during spraying Generally, the distance between the spray gun and the working surface shall be about 100 mm The angle between the spray gun and the base surface of the steel structure shall be kept vertical, or the spray nozzle shall be slightly inclined upward ⑥ During spraying, the nozzle shall move in parallel, and the movement shall be stable, the speed shall be consistent, and the coating shall be uniform However, when spraying is adopted, the thickness of the general coating is relatively thin, so it should be sprayed several times more, and each spraying should be carried out when the upper paint film has dried Application scope: red lead alkyd antirust paint is suitable for steel structures on land, parts above waterline of ships, steel machinery and equipment, etc., and can be used with phenolic, alkyd and other top coats Packaging, storage and transportation: ① red lead alkyd antirust paint shall be stored in clean, dry and sealed containers During storage, it shall be kept ventilated and dry to prevent direct sunlight, and shall be isolated from the fire source and away from the heat source When the temperature is too high in summer, it shall be cooled ② Red lead alkyd antirust paint shall be protected from rain and sunlight during transportation, and shall conform to relevant regulations of transportation department ③ The effective storage period of red lead alkyd antirust paint is 1 year If it exceeds the storage period, it can be inspected according to relevant regulations If it meets the technical requirements, it can still be used Home of
