蒸压无石棉纤维水泥板鼓泡分层现象原因及解决措施

Causes and Solutions of the Bubbling and Delamination in Autoclaved Asbestos-Free Fiber Cement Board

结合实际生产,分析了蒸压无石棉纤维水泥板生产过程中鼓泡分层现象的原因,并结合实际生产,从提高坯料黏结力(优化原材料加工处理、回水回料控制、外加剂的应用、板材的压制工艺、优化预养、蒸养制度等)和优化养护制度出发,提出了相应的解决措施,以期为蒸压无石棉纤维水泥板的生产提供参考借鉴。

Based on the actual production,the causes of the bubble and layering phenomenon in the production process of autoclaved asbestos-free fiber cement board were analyzed,and in combination with the actual production,in order to improve the bonding strength of the blank(optimize the processing and treatment of raw materials,return water and return material)Control,application of additives,pressing process,optimization of pre curing,steam curing system,etc.)and optimization of curing system,the corresponding solutions are put forward in order to provide a reference for the production of steam pressed asbestos-free fiber cement board.
