Method for producing cement by adding naphthalene sulfonate water reducing agent
The invention belongs to the technical field of preparation of naphthalene sulfonic acid, and discloses a cement production method by adding a naphthalene sulfonate water reducing agent. The method comprises the following steps: adding a naphthalene sulfonate formaldehyde condensate, sulfonated melamine formaldehyde resin and an optional chromium remover into a cement mixture, grinding to obtain cement powder, and weighing and packaging to obtain the cement added with the naphthalene sulfonate water reducer. In the cement grinding process, the naphthalene sulfonic acid formaldehyde condensate prepared by the microwave method is mixed and matched with the chromium removal agent for use, so that a good chromium removal effect is achieved, and the content of polluting chromium in a cement finished product is reduced.
本发明属于萘磺酸的制备技术领域，公开了一种添加萘磺酸盐减水剂的水泥生产方法。该方法包括在水泥混合料中添加萘磺酸甲醛缩合物、磺化三聚氰胺甲醛树脂，以及任选地除铬剂，并进行粉磨加工，得到水泥粉末，经称重、封装，得到所述添加萘磺酸盐减水剂的水泥。本发明在水泥粉磨工序中将经过微波方法制备的萘磺酸甲醛缩合物与除铬剂混合搭配使用，达到了良好的除铬效果，降低了污染性铬元素在水泥成品中的含量。
