为解决采空区内液体阻化剂易从岩石缝流失的问题,通过正交试验、对比试验及热重分析,研究新型液体阻化泡沫的发泡性能和阻化性能.结果表明:当AES、MPS、CMC、MgCl_2质量分数分别为0.5%、0.2%、0.1%、5%时,阻化泡沫综合性能最佳.随着AES或CMC质量分数增大,发泡倍数先增加后减小,泡沫稳定性和保水性降低;随着MPS质量分数增大,发泡倍数降低,析液半衰期和保水性先增加后减小;随着MgCl_2质量分数增加,发泡倍数和析液半衰期先增大后减小,保水性增强;阻化泡沫的阻化效果较好.
In order to solve the problem that the liquid inhibitor in the mined area is easily lost from the rock seams, the foaming property and the resistance-deteriorating property of the new liquid resistance foam were studied by orthogonal test, comparative test and thermogravimetric analysis.The results showed that when AES , MPS, CMC and MgCl 2 were 0.5%, 0.2%, 0.1% and 5%, respectively.The results showed that with the increase of mass fraction of AES or CMC, the expansion ratio first increased and then decreased, Foam stability and water retention decreased. With the increase of MPS mass fraction, the foaming multiple decreased and the half-life and water retention of the liquid increased firstly and then decreased. With the increase of mass fraction of MgCl 2, the foaming multiple and the half-life of the liquid first increased After the reduction, enhanced water retention; resistance of the resistance of the foam better.
