目前有许多石棉水泥制品企业都用玻璃丝代替部分石棉生产石棉水泥管.但玻璃丝表面光滑,吸附水泥颗粒的性能较差,因而使回水浓度增大,造成大量水泥流失.另外,用玻璃丝制石棉水泥料浆时容易打团,难于松解.因此,用玻璃丝生产石棉水泥管时,必须采取一些相应措施.我们采取浓浆低水位的方法就可 Many asbestos cement products companies currently use glass fiber instead of some asbestos to produce asbestos cement pipes. However, the surface of the glass fiber is smooth, and the performance of adsorbing cement particles is poor. As a result, the backwater concentration is increased and a large amount of cement is lost. In addition, glass wool is used to make asbestos. Cement slurries are prone to cracking, making it difficult to release. Therefore, when producing asbestos cement pipes with glass wool, some corresponding measures must be taken. We can adopt the method of thick slurry low water level.
