两组分的聚氨基甲酸乙酯浆材广泛用在采煤作业申,固结岩石和煤层或者用来止水,也专为隧道发展了特殊的浆材系统,而且已在实际应用中取得成功。本文介绍两组分浆材的化学性质、物理性质及使用方法,并举出一些在不同情况下成功应用的实例。
Two-component polyurethane pastes are widely used in coal mining operations to consolidate rock and coal seams or to stop water, and a special slurry system has also been developed specifically for tunnels and has been successful in practical applications . This article describes the chemical properties, physical properties, and methods of use of the two-component slurry and gives examples of successful applications in different situations.
