US06995105B1 Use of water-soluble mixed polymers as a flowing medium and/or as a hardening retarder for refractory materials which contain aluminate cement 失效
使用水溶性混合聚合物作为流动介质和/或用作含有铝酸盐水泥的耐火材料的硬化缓凝剂

Use of water-soluble mixed polymers as a flowing medium and/or as a hardening retarder for refractory materials which contain aluminate cement
摘要：
The use of a three-component water-soluble polymer comprising 5–90% by weight of a component a), preferably of the maleic acid, fumaric acid or itaconic acid type, 5–90% by weight of a component b) essentially from the group consisting of 2-acrylamido-2-methylpropanesulfonic acid, vinylsulfonic acid and vinylphosphonic acid, and 5–90% by weight of a component c) comprising acrylic acid, methacrylic acid, acrylamide or methacrylamide, as fluidizer for refractory compositions comprising alumina cement is described. The copolymer, which has a preferred molecular weight Mw of
摘要（中）：

使用包含5-90重量％的组分a），优选马来酸，富马酸或衣康酸的三组分水溶性聚合物，5-90重量％的组分b）基本上由 由2-丙烯酰胺基-2-甲基丙磺酸，乙烯基磺酸和乙烯基膦酸组成的组和5-90重量％的包含丙烯酸，甲基丙烯酸，丙烯酰胺或甲基丙烯酰胺的组分c）作为用于包含氧化铝水泥的耐火组合物的流化剂 被描述。 具有优选的分子量为50,000的共聚物也可以与另外的质量改进添加剂如二氧化硅，石灰或苏打混合，以及用于耐火组合物的进一步的常规添加剂。
