与一般无机和有机粘结剂相比,有关磷酸水玻璃粘结剂的报道还比较少。磷酸在某些自硬砂中被用作催化荊,但它与水玻璃接触后,会立即使水玻璃析出凝胶而失去作用。我们根据国内外有关信息,对磷酸水玻璃粘结剂进行了有限的实验室试验和生产试验。试验表明,它对需要高温强度、抗高温热震的热工作业,有着潜在的价值。 Compared with the general inorganic and organic binders, there are still few reports on phosphogypsum binders. Phosphoric acid is used as a catalyst in some hard sands, but when it comes in contact with water glass, the water glass immediately precipitates out of the gel and loses its effect. According to the relevant information at home and abroad, we conducted a limited number of laboratory tests and production tests on phosphoric acid glass binders. Experiments show that it has potential value for thermal work that requires high temperature strength and thermal shock resistance.
