A kind of low-cost non-drying glue was produced with the waste foamed polystyrene plastics(FPS) as main raw material and reagents such as solvent,plasticizer,emulsifier and thickener.

以废弃聚苯乙烯泡沫塑料为原料,通过对溶剂、增塑剂、乳化剂及增稠剂的筛选,研制出了一种低成本的不干胶,对该不干胶的配方进行优化选择,对其性能指标进行了测试。

In this paper,the method to make non-drying glue by modifying polystyrene foamed plastic waste was presented.

本文介绍了废聚苯乙烯泡沫塑料的资源化再利用—改性制备不干胶的方法;对制备工艺和产品的性能进行了优化;实验结果表明此方法制备的不干胶具有良好的不干性能,粘度大,耐水性好等优点。

Because existing the problem of “inexhaustible pumping”, the foundation pit engineering is still affected by groundwater, and the validity of the soil nailing can be decreased or lost, even .

“疏不干”是基坑垂直井点降水工程中常遇到的一种地质工程现象 ,基坑降水“疏不干”的根本原因是垂直井点降水无法切断待疏干区内外地下水的水力联系 ,区外水不断补给区内 ,并达到补给-疏排动平衡。
