It is widely used in our daily life Membrane structure landscape The service life of our membrane structure data is much longer than that of other data, but it is still inseparable from our maintenance. Then let's hurry up and have a look at the content of this aspect with us!
1. The scraper coating method mainly uses a scraper to apply a certain amount of coating liquid on the substrate. The thickness of the coating is adjusted by the gap between the scraper and the substrate. This method can process thin materials, and this method can apply coatings of different materials on both sides of the membrane material.
2. Roller coating method This method is to use several rollers to apply the coating liquid on the substrate while handling.
3. Sculpting roller coating method This method is a combination of scraper coating method and roller coating method. The coating liquid attached to the convex part of the concave convex cutting roller on the surface is scraped off by the scraper, and the coating liquid in the concave part is quantitatively transported to the substrate. Titanium dioxide film material coating is processed by this method.
4. The roller method uses a heating roller to roll the coating liquid into a film. After several rollers combine the coating film with the substrate, this method can be used for thick coating processing, and can also accurately adjust the thickness of the coating.
5. Keep away from acid-base substances. Acid-base substances are the killer of the film structure scene. Acid-base substances have corrosive effects on steel structures and film materials. If the steel structure is accidentally stained with acid (such as sulfuric acid, vinegar), alkali (such as methylamine, soapy water, soda water), immediately flush the dirt with clean water, and then dry it with dry cotton cloth. Avoid acid and alkali corrosion of steel data.
Through the above understanding, we know that these methods can ensure the service life of membrane structure landscape.
