摘要
砂岩环保吸声板是砂粒聚合而成,主体材料为二氧化硅无机物,具有天然的理化性能优势,抗压强度可达29.7 MPa,耐火等级A2,吸声系数可达0.50?0.85,环保性好,耐水耐酸碱,完成面不开裂;并介绍了在保定长城汽车高技术研发中心报告厅的应用。
Host material of sand acoustic panels is of silica inorganic, having natural advantages of physical and chemical properties： compressive strength 29.7 MPa, combustibility rating A2, sound absorption coefficient 0.50-0.85, environmental friendly with water and acid endurance, surface no crack absolutely. There are dozens of applications cases in China, in this paper, an R＆D auditorium of Baoding Great Wall Automobile is discussed in details.
