Surface treatment and construction process analysis of plastic spray paint elastic coating

2021-07-19 11:14:35

As a volatile paint, elastic paint can form a coating with good hardness, gloss, water resistance, acid and alkali resistance, and pollution resistance during the painting process. However, during the construction of elastic coatings , environmental pollution problems are likely to occur, and the coating has poor air permeability, prone to peeling, peeling and other problems. It is hoped to ensure the beauty of the coating layer and avoid problems such as small cracks during construction, so as to well control the construction quality.

Elastic coating base treatment.

To ensure the construction quality of elastic coatings and prolong the service life of the coatings, the basic treatment of elastic coatings should be strengthened. It can be said that the quality of the basic treatment directly determines the construction quality of the coating. In the treatment of the base layer, it not only has a direct impact on the adhesion of the coating, but also has an impact on the service life of the coating and the effect of the device. Therefore, it is necessary to pay more attention to this process before coating construction, including: substrate, surface treatment methods and requirements.

The first is concrete plastering and concrete base treatment projects. According to relevant national laws and regulations on construction projects, concrete and concrete plastering bases should be smooth on the surface, dense on three sides, and the pH value of the base should be controlled below 10. In addition, the plastering plane should also ensure that the plastering is firm, neat and tidy, and the surface oil, dust, splashes, mortar flow marks and other sundries should be removed in time. The protruding parts and falling objects on the concrete surface should also be removed in time during the actual application process. In the actual construction process, some problems should be dealt with in time. For example, if efflorescence appears on the surface of the concrete plaster base, it can be neutralized with a 3% oxalic acid solution, and then rinsed with water. If the surface of the concrete plastering base layer has hollowing, peeling, sanding, etc., it should be cleaned with a spatula or wire brush. After cleaning, it should be rinsed with water and then fully repaired. If there is a problem with the old grout on the concrete base layer, the surface of the old grout can be washed with clean water to dissolve it, and then use a spatula to scrape off the old grout.

The next step is the treatment of the wooden base. During the construction process, the moisture content of the wooden base should not exceed 12%, and the surface of the wooden layer should be flat and clean, and there should be no dust and oil. The cracks, burrs, fat sacs and other issues on the surface of the wood base should also be paid attention to. Clean up in time, and use putty for smoothing and polishing to ensure that the wood base is clean and tidy. For the cleaning of the wooden base, different cleaning methods are required, such as warm water, soapy water, and alkaline water. For example, when dealing with oil stains and glue stains on the surface of wooden substrates, alcohol, gasoline or other solvents can be used, and then clean with water. If it is to treat the resin dirt on the surface of the wood base layer, alcohol, gasoline, benzene, carbon tetrachloride, etc. can be used, or 4%-5% NaOH solution can be used. To avoid resin exudation fundamentally, shellac paint can be used to remove the resin first, and then shellac can be used to seal the part where the resin has exuded.
