摘 要: | 分别以玉米淀粉、小麦淀粉、马铃薯淀粉为原料,采用二步法按不同配比制备多层瓦楞纸生产线用淀粉胶黏剂,并对其性能进行研究。结果表明,糊化温度随淀粉胶质量分数和NaOH质量分数的增大而降低;SteinHall黏度随NaOH质量分数增大先减小,当NaOH质量分数超过0.7%时,Stein-Hall黏度迅速增大。在同一温度时,Brabender黏度从大到小依次为马铃薯淀粉胶、小麦淀粉胶、玉米淀粉胶;经过同一放置时间时,Brabender黏度从大到小依次为马铃薯淀粉胶、玉米淀粉胶、小麦淀粉胶。

Properties of Starch Adhesive for Multi-layer Corrugated Paper |
| |
Abstract: | Starch adhesive for the multi-layer corrugated paper line was prepared with corn starch , wheat starch and potato starch as raw starch materials by way of Stein-Hall with different proportion to study the properties of starch adhesive .With the increase of adhesive concentration and the content of NaOH , the pasting temperature was decreased .With the increase of the content of NaOH , the Stein-Hall viscosity was decreased at first and then increased rapidly when the content of NaOH was beyond 0.7%;at the same temperature , the Brabender viscosity in the descending order was:potato starch adhesive , wheat starch adhesive , and corn starch adhesive .For the same storage time , the Brabender viscosity in the descending or-der was:potato starch adhesive , corn starch adhesive , and wheat starch adhesive . |
