Problems solved by technology

[0002] Polyurethane coating is a kind of coating with excellent comprehensive performance, which is widely used in wood decoration and wooden floor. Since wooden furniture or wooden floor will use adhesives containing formaldehyde in the process of manufacture and use, it will slow down during use. It is released slowly. At present, there is no good way to remove formaldehyde in home decoration. Therefore, the removal of formaldehyde is a matter of great concern to residents. The release of formaldehyde is not conducive to the health of the home environment.
