Design and Application of Foam Gel Preparation System
摘要
Abstract
The foam-gel preparation system is constructed, and the key equipment includes foam-forming device, double-liquid grouting pump and flow stabilizer. The preparation process of foam gel was determined. After adding foaming agent to water to form the mixed liquid with the dual-liquid grouting pump, the foaming device was used to foam. The formed foam and the added gelling agent mix and gelling reaction occurs to form the foam gel. The working pressure of the double-liquid grouting pump is 0.4 MPa and the flow rate is 100 L/min. Anti-fire test shows that foam gel can quickly extinguish fire and prevent fire from re-burning.关键词
