介绍中性造纸专用胶AS39A在亚铵草浆上的应用实验情况,实验结果表明,AS39A应用于难施胶的亚铵草浆,获得了良好的中性施胶效果。适宜的中性施胶条件为:硫酸铝用量1.0%,3901胶料用量0.8%,3902胶料用量0.6%,3903胶料用量0.4%,碳酸钙用量5%-25%,施胶顺序为逆向施胶。
This paper introduces the application of AS39A for neutral papermaking specialty pulp in the process of ammonium sulfite pulp. The experimental results show that AS39A is suitable for the application of hard ammonium glufoma pulp with good neutral sizing effect. The suitable neutral sizing conditions are as follows: the dosage of aluminum sulfate is 1.0%, the dosage of 3901 rubber is 0.8%, the dosage of rubber of 3902 is 0.6%, the dosage of rubber of 3903 is 0.4% and the dosage of calcium carbonate is 5% -25% Sizing.
