摘要： 为提高预制混凝土构件的脱模效果，以乳液稳定性为评价指标，采用三因素四水平正交试验，研究了乳化剂用
量、乳化温度以及乳化速度对生物质柴油乳液稳定性的影响规律。结果表明：乳化剂用量是影响生物质柴油乳液稳定
性的重要因素，而乳化速度对乳液稳定性的影响不明显。得到的生物质柴油乳液最佳工艺条件为：乳化剂用量4%、乳
化温度60 ℃、乳化速度1 400 r/min。加入0.7%的助剂后得到生物质柴油基预制混凝土构件脱模剂。进一步采用直观分
析法和现场施工检验该脱模剂的脱模效果，发现其施工便宜，脱模顺利，得到的预制构件棱角完整，表面光滑、无气孔
麻点，且脱模后的台座表面洁净度高。

Abstract: To improve the release effect of precast concrete components, take emulsion stability as evaluation index,
the influence of emulsifier dosage, emulsifying temperature and emulsifying speed on the stability of biomass diesel
emulsions is studied by three factors and four levels orthogonal test. The results show that the amount of emulsifier is
an important factor affecting the stability of biomass diesel emulsion, while the emulsifying speed has little effect on
the stability of the emulsion. The optimum conditions for the biodiesel emulsion are as follows: emulsifier dosage 4%,
emulsification temperature 60 ℃, and emulsification speed 1400 r/min. After adding 0.7% additives, the biomass diesel
based release agent for precast concrete components is obtained. The demoulding effect of the release agent was
further tested by visual analysis method and on -site construction, and it was found that the construction cost was cheap,
the demoulding was smooth, and the edges and corners of the precast components were complete, the surface was
smooth without any pores and pits, and the surface cleanliness of the pedestal after demouldling was high.
