摘要：
The purpose of this study was to obtain three foam formulations of great foaming and stability based on response surface methodology. The factors of response were SDS, Fc-134, 6501 and mica powder #2000 through signal factor experiments. Foaming height and foam stability were the responses to study the interaction. According to Box-Benhken method, quadratic regression model was established which was significant and reliable. Using the model to predict concentration of these reagents, the optimum concentration of SDS, Fc-134 and 6501 was 2.64%, 0.096% and 3% respectively. The optimum dosage of mica #2000 was 10g. Under the optimum conditions, the predicted value of foaming height and stable time was 1550 ml and 12.8792 min respectively, meanwhile the experimental verification was 1550 ml and 12 min respectively. The error of these was 1.05% and 6.82%.Compared with un-optimized three phases foam, optimal design of three phase foam made improvement in foaming height and stable time which were increased by 14.8% and 26.3%, respectively. Results showed that optimal designed three phases foam has a greater performance of foaming and stability than the un-optimized one. The prediction error is small. It can be used for improving foaming and stability of the three phases fire-fighting foam, providing a reference for three phases foam formulation design. © All Right Reserved.
