Problems solved by technology

[0002] Wood is an indispensable material for modern decoration and decoration projects. The amount of wood used in modern decoration projects is increasing, and the quality requirements are getting higher and higher. It is difficult for ordinary wood to achieve fire resistance, safety performance and decorative effects.
At present, the adhesives used in flame-retardant solid wood multi-layer decorative panels have poor fire resistance, and generally contain formaldehyde solvents, which will affect the human body or the environment.
