Preparation method of polycarboxylate superplasticizer powder
The invention discloses a preparation method of polycarboxylic acid water reducing agent powder, which comprises the following steps: carrying out reduced pressure distillation dehydration on a polycarboxylic acid water reducing agent, slicing the dehydrated material, and crushing to obtain the polycarboxylic acid water reducing agent powder. The preparation method of the polycarboxylate superplasticizer powder has the advantages of simple and safe production equipment, high productivity, low production cost, no influence on product quality and the like, is suitable for large-scale production, and is beneficial to reducing the transportation cost of polycarboxylate superplasticizer products.
本发明公开了一种聚羧酸减水剂粉剂的制备方法，其包括以下步骤：将聚羧酸减水剂水剂进行减压蒸馏脱水，再将脱水后的物料切片，再进行粉碎，即得聚羧酸减水剂粉剂。本发明的聚羧酸减水剂粉剂制备方法具有生产设备简单安全、产能大、生产成本低、对产品质量无影响等优点，适合进行大规模生产，有助于降低聚羧酸减水剂产品的运输成本。
