Problems solved by technology

Although the performance is excellent, it must be used through the combination of masking materials on the upper and lower surfaces of the honeycomb core. The materials of the masking boards are generally aluminum boards, ceramic tile boards, solid wood boards, gypsum boards, cement boards, magnesium fireproof boards, natural marble boards, composite melamine Plates, etc. The processing procedures of these materials are relatively complicated and the cost of materials is relatively high, which limits the scope of application in some markets
[0004] Generally, the components of the fireproof board are bonded by organic adhesives. The aluminum, plastic, paper materials and adhesive materials in the honeycomb core have poor heat resistance. Cause heavy property damage and other losses
[0005] With the increasingly higher requirements for high-grade fireproof materials in various fields, the traditional honeycomb core composite material combined with the fireproof board of the masked decorative board obviously cannot meet the market demand for high-grade fireproof materials.
