无石棉纤维水泥平板的透水性的比较研究

Comparative Study on the Water Permeability of Non-Asbestos Fiber Cement Flat Sheets

论文讨论了无石棉纤维水泥平板底材对透水性的影响因素,比较了三种使用量最大的底材的外观和特性,介绍了它们的差异和优缺点。测试了三种底材在不同时间的透水值,讨论了透水值的大小和离散程度,评价了底材的质量。通过比较和分析探讨出底材的初始透水性值可能是影响透水性的关键因素。

This paper discussed the influence factors of non-asbestos fiber cement flat sheet substrate on water permeability,compared the appearance and characteristics of three substrates with the largest usage,and introduced their differences,advantages and disadvantages.The water permeability values of three substrates at different times were measured,the size and dispersion of the water permeability values were discussed,and the quality of the substrates was evaluated.Through comparison and analysis,it is found that the initial water permeability of the substrate may be the key factor affecting the water permeability.
