磷石膏用作表面施胶剂的研究

The Research on the Application of Phosphogypsum as Surface Sizing Agent

磷石膏作为瓦楞纸专用新型的表面施胶剂替代传统淀粉施胶剂,优势如下:成本低、耐返潮、成纸环压高,完美契合市场需求。通过对磷石膏实验室实验,确定其可替代40%的淀粉用作表面施胶剂,成纸环压提高,成本大幅下降。通过纸厂(河南恒丰纸业)上机试验,确定其可替代25%的淀粉用作表面施胶剂,成纸抗水性增强,环压提高,耐返潮性能提高。

Phosphogypsum,as a new surface sizing agent for corrugated paper replacing the traditional starch sizing agent,has the following advantages of low cost,moisture resistance and high ring pressure,which perfect meets the market demand.Through the experiment of phosphogypsum in laboratory,it is determined that phosphogypsum can replace 40% of starch as surface sizing agent,and the paper ring pressure is increased and the cost is greatly reduced.The paper mill(Henan Hengfeng Paper) was tested on machine,proving that it could be used as surface sizing agent replacing 25% of the starch agent.
