There are two kinds of poly sandboard base materials, one is the reinforced glass fiberboard with excellent sound absorption and fire prevention as the substrate, this substrate is well known to everyone, and it is also a high-end sound-absorbing material commonly used by many designers; the other is The base material is made of light sand particles with a specific diameter as the raw material. Through polymerization technology, each particle is aggregated together like welding. Due to the irregular shape of the surface of the inorganic particles or the aggregation gap, a large number of irregularities are formed between the particles. and interconnected microscopic pore structures.
When the sound is incident to the surface of the poly-sand board, the sound wave will penetrate the inside of the board and spread in the fine pores, due to the viscosity and frictional resistance of air movement, the sound energy is converted into heat energy and consumed, resulting in sound absorption. The high, medium, and low-frequency characteristics of the sound absorption of the poly-sand board are closely related to the size, number, and structure formation of the fine pores between the sand grains.
During the polymerization process, the size and arrangement of internal pores are controlled by precisely regulating the number of inorganic particles, and the speed, and strength of the polymerization reaction, thus forming finishes with different acoustic and decorative effects, while the surface of each particle is covered with a special maintenance agent, forming a special lotus leaf effect, which makes it impossible for water molecules to enter the interior of the material. This process produces products with high strength, excellent fire resistance, and water, and moisture resistance. And polymerization technology in the polymerization of materials using environmentally friendly plant formula, the finished product without any organic volatiles, is a green acoustic decorative material.
