The addition of rare earth inorganic composite material enables the mineral wool board to have surface activity, strongly adsorbs and decomposes toxic substances such as formaldehyde generated during the decoration process, and has the chemical property of an ion exchanger so as to effectively increase the concentration of oxygen ions in the air. Greatly improved living space. The addition of expanded perlite with fireproof and heat insulation functions effectively reduces the cost of refrigeration and heating and meets the energy-saving and consumption-reducing needs of people in the new era.
