石棉水泥波瓦是“轻型屋面”中最主要的建筑材料,它是由石棉和水泥制成的波形薄板,具有耐热、耐侵蚀、耐冻、强度高等物理化学性能.由于它的张幅大、重量轻,并且具有装配性,因而施工中非常方便,不受季节和气候变化的影响,这些性能不但能节约工时,还可以大大的缩短施工进度. 根据波形高度,石棉水泥波瓦在国内一般分大波、中波、小波等三种类型,目前除西安石棉水泥制品厂正式生产大波石棉水泥瓦以外,其他所有企业,都生产小波石棉水泥瓦,这是值得研究和探讨的问题. 大波石棉水泥瓦,是苏联和其他国家大量生产的
Asbestos Cement Bowa is the most important building material in “light roofing”. It is a corrugated sheet made of asbestos and cement. It has heat-resistant, erosion-resistant, freeze-resistant, and high-strength physical and chemical properties. Due to its large width It is lightweight, and it has assembly, so it is very convenient in construction. It is not affected by the seasons and climate change. These performances can not only save man-hours, but also greatly reduce the construction progress. According to the waveform height, asbestos-cement tile is generally used in China. There are three types: Dabo, Zhongbo, and wavelet. Currently, except Xi’an Asbestos Cement Products Factory, which officially produces Dabo asbestos cement tile, all other companies produce wavelet asbestos cement tiles. This is a problem worthy of study and discussion. Dabo Asbestos Cement Watts, produced in large quantities in the Soviet Union and other countries
