Suitable for wet end addition of various types of paper, selecting modified starch with appropriate substitution degree, and achieving ideal results by adjusting its dosage and addition position.
Features and advantages:
1. Improving the performance of paper: It can significantly enhance the physical indicators such as tensile strength, burst resistance, folding resistance, and ring compression strength of paper, improve the grade of paper, and reduce the proportion of wood pulp.
2. Good retention and filtration effects: using high degree of substitution modified starch can improve the retention of small fibers, increase paper weight, reduce pulp consumption, and lower white water concentration; It can also increase the speed of the paper machine, save energy consumption, and reduce wet end breakage.
3. Improving sizing effect: It can save the amount of sizing agent used, especially as a supporting auxiliary for neutral sizing.
