近年来,石棉水泥波瓦质量下降的原因之一,是大量使用短棉。那么,在大量采用短棉的条件下,通过生产工艺和设备的改进,能不能提高波瓦的质量呢?本文试就这个问题进行讨论。一、石棉纤维分布与石棉水泥制品强度石棉水泥制品中,拉应力主要由石棉纤维来承受。因此,提高制品强度的实质,就是提高石棉与水泥的结合强度,以充分发挥石
In recent years, one of the reasons for the decline in the quality of asbestos-cement pots is the heavy use of short cotton. So, under the conditions of using a large number of short cotton, through the improvement of production processes and equipment, can not improve the quality of the wave? This article tries to discuss this issue. 1. Asbestos Fiber Distribution and Asbestos Cement Product Strength In asbestos cement products, tensile stress is mainly supported by asbestos fibers. Therefore, the essence of improving the strength of products is to increase the bonding strength of asbestos and cement to give full play to the stone.
