研究了添加剂对磷酸盐粘结剂抗湿性的影响。结果表明，添加少量ＹＪＧ有机高分子材料作抗湿剂，可显著提高其抗湿性，同时使其干强度有所提高。 The effect of additives on the moisture resistance of phosphate binders was studied. The results show that the addition of a small amount of YJG organic polymer materials as anti-wetting agent can significantly improve its moisture resistance, while increasing its dry strength.
