一、发展简史石棉水泥板(Asbestos Cement Shreet简称ac板)具有两个优势,一是材料性能优势——轻质,高强,耐火,抗冻,不燃,热阻电阻高,加工性能好;二是高效率工业化生产方式的优势。由于这些优势的逐步发挥,使产品在建筑技术上的重要作用和经济上的重要意义日益突出,应用范围日益 First, the development of a brief history of asbestos cement board (Asbestos Cement Shreet referred ac plate) has two advantages, one is the material performance advantages - light weight, high strength, fire resistance, frost resistance, non-combustible, high thermal resistance, good processing performance; It is the advantage of a highly efficient industrial production method. Due to the gradual exertion of these advantages, the important role of the product in building technology and the importance of the economy are becoming increasingly prominent.
