(a) the cbsa brand, which belongs to beijing american materials technology ltd., is a science, technology and innovation enterprise focused on the development and design of high-end wall materials, which entered the field of decorative materials and created the cbsa brand in 2009; he is the director of the china association of building and decoration materials, the association of silicon algae industries. The research and development of trans-silican mosaic products has been further upgraded, and the development and introduction of a new generation of "dan-mima" silican mosaics has improved material hardness, water intake and skin-colored products. By 2017, the country was keen to improve its product system and become a leading firm in the development of industrial products, such as silica mosaics, dry powdered silica mosaics, new grey slurries, and processes to imitate natural high-end high-functional products such as jade, water grinding, and hantonstone. To this end, the u. S. Has a series of thousands of colored processes. At the same time, the company's products meet the radiation standards of the silicon algae sludge industry (gb), category a construction materials through rigorous testing. The main raw material of the mesmopolitan mosaic is silican algae, which has been formed over hundreds of millions of years — silican soil — as an algae living in the oceans and lakes. Silicon algae mud uses natural materials derived from the sedimentation of silicate algae, aquatic plankton living millions of years ago, consisting mainly of proteins, rich in a variety of useful minerals, and soft in the mass, with electron microscopes showing numerous tiny holes in the particle surface, with a pore rate of over 90 per cent, up to 65 m2/g above the surface area. The eight functional characteristics of the mesmeric silican mud are: respiration to wet, air purification, fire resistance, noise reduction, heat insulation, release of anaerobic ion, absence of dust, soft colour. It has a coloured soil, high temperatures and colours, a large amount of water sprayed with no color, no mud, and a light stroke of hands, with natural mud effects. The powder, mixing and construction have no scent and no harmful substances have been released. It is fine and has small grains of sand and is suitable for construction on a flat and dry interior wall. Water absorbs, fire does not burn, and does not smell stingy。
