改性纸浆废液复合粘结剂

Modified Pulp Waste Liquid Complex Binder

简述了改性纸浆废液复合粘结剂及其用作铸造砂芯粘结剂时的性能。实验表明，该粘结剂的发气量小于合脂砂，溃散性良好，干拉强度为１．７ＭＰａ．

The properties of modified pulp waste liquid complex binder and those of the binder used as cast cores are discussed briefly. The experiment shows that: the gas forming volume of the binder is less than the synthetic fatty residual sand, and its collapsibility is good and the dry tensile strength is 1.7MPa.
