Membrane structure landscape How are materials maintained?
Membrane structure landscape is widely used in people's daily life, and its service life of membrane structure materials is much longer than other materials, but it is still inseparable from our maintenance. So let's learn about this!
1. The scraper coating method is mainly to apply a certain amount of coating liquid on the substrate with a scraper. The coating thickness is adjusted by the gap between the scraper and the substrate. Thin materials can be processed, and the front and back sides of different materials can be coated on the membrane materials.
2. Roller coating method: the coating liquid edge is coated on the base cloth along the transfer edge by a plurality of rollers.
3. Carving cylinder coating method This process is a combination of scraper coating method and cylinder coating method. The convex part of the concave convex carving cylinder on the surface is attached with coating liquid. The scraper scrapes off the coating liquid in the concave part, and quantitatively transfers the coating liquid in the concave part to the substrate. Titanium dioxide film material coating is coated by this method. The roller method uses a heating roller to roll the coating liquid into a film. After several rolls, the coating film is combined with the substrate. This method can be used for thicker coating processing and more accurate adjustment of coating thickness.
4. Keep away from acid and alkali substances. Acid and alkali substances are the killers of membrane structure landscape. Acid and alkali 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, soap solution, soda), the stain should be immediately washed with clean water, and then dried with dry cotton cloth. Prevent acid and alkali corrosion of steel materials.
Through the above understanding, let us know that these methods can ensure the life of membrane structure landscape. Under the premise of good maintenance, the service life of membrane structure landscape can be increased.
