Widely used in our daily life Membrane structure landscape Its service life is much longer than that of other materials, 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 is mainly to use the 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 be used to 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 uses several rollers to transfer the coating liquid edge onto the substrate.
3. Carving cylinder coating method This method is a combination of scraper coating method and cylinder coating method. The coating solution attached to the convex part of the concave and convex carving cylinder on the surface is scraped off by the scraper, and the coating solution in the concave part is quantitatively transferred 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 killers of membrane structure landscape. Acid-base substances have corrosive effects on steel structures and membrane 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 materials.
Through the above understanding, let us know that these methods can ensure the service life of membrane structure landscape.
