To address the common issue of powder falling off from high-performance wooden columnar activated surfaces, Taixin Company has developed a new product - a surface treatment agent. Simply spray the treatment agent onto the surface of the columnar carbon after it comes out of the kiln, allow it to dry naturally, and a very thin protective layer will form. This has little impact on the adsorption performance of the columnar carbon, is environmentally friendly and non-toxic, and can solve the powder falling off problem, improving the appearance of the columnar carbon product.
