How to use sulfuric acid paper

Sulfuric acid paper is actually sulfuric acid transfer paper, which is often used in the printing industry. The paper quality of sulfuric acid paper is not only very pure, but also very strong. It also has the advantages of good transparency, no deformation, sun resistance and high temperature resistance, and the anti-aging effect is also very good. Therefore, many people use it for manual drawing, laser printing and art printing, etc. So how to use sulfuric acid paper?

How to use sulfuric acid paper? By understanding the above content, you can master how to use it. Sulfuric acid paper is made of fine plant fibers that are interwoven with each other, pulped in a wet state, without sizing or filling, and paper-made. It is then soaked in 72% concentrated sulfuric acid for 2 to 3 seconds, washed with water, treated with glycerin, and dried to form a hard, film-like material. Sulfuric acid paper is solid, dense and slightly transparent. It has strong resistance to penetration by grease and water, is airtight, and has high wet strength. It is waterproof, moisture-proof, oil-proof, and can kill bacteria and disinfect.
