| 目的 研究降低酒精润版液中酒精浓度的方法。方法 首先将赛飞扬FS12-100润版液用纯净水配制成质量分数为3%的原液， 测试表面张力； 然后将不同质量分数的酒精和表面活性剂6501分别添加到原液中， 测试表面张力； 最后将不同质量分数的酒精和表面活性剂 6501 同时添加到原液中， 测试表面张力。结果 在原液中添加质量分数为0.1%的表面活性剂6501和5%的酒精， 表面张力最低为 23.37 mN/m， 可将酒精的质量分数由 12%降低到 5%。结论 表面活性剂 6501 与酒精混合配制成新型的低酒精润版液是可行的。 |

| Abstract: |
| Objective To study the way to lower the concentration of alcohol in alcohol dampening. Methods First, FS12-100 dampening solution and pure water were used to make the original solution with 3% of FS12-100 dampening solution and the surface tension was tested. Then different concentrations of alcohol and the surfactant‘6501’were added separately and together to test the different surface tensions. Results Based on the experimental data, addition of 0.1% of ‘6501’and 5% of alcohol in the fountain solution could reduce the concentration of alcohol from 12% to 5%, achieving the lowest surface tension, 23.37 mN/m. Conclusion Preparation of novel low-alcohol fountain solution by mixing the surfactant '6501' and alcohol was feasible. |
