大功率超声参量与表面活性剂物化参量的匹配关系

In order to protect the ozone sphere above the South Polar, the ODS (Ozone depleting substance) cleaning method will be forbidden all over the word in 21st century. As the specific action, the ultrasonic cleaning is being to a research focus for replacing the ODS cleaning method in the word. It is independent in old days that study on the ultrasonic cleaning technology and the detergent development. The effect of high power ultrasonic parameters on the sical-chemistry performance of surface active agent used for industrial detergent was studied in this project. Followings are the main:An ultrasonic generator with the automatic control on the equency-tracking and the constant vibration amplitude was developed. Its power could be adjusted from 0-600W..The vibrating internal-loss-heat of some typical metal was studied. High power ultrasonic transducers are developed and the frequency is 25kHz, 30kHz, 40 kHz, 60 kHz and 80 kHz respectively.A measurement method of ultrasonic cavatation intensity was studied based on the analysis of local pressure.The sonochemistry reactor with double temperature control was invented. The key of temperature control of sonochemistry reactor in tank style is solved.The ultrasonic effect on the performance of detergent solutions was studied.The matching between ultrasonic parameters and the parameter of some typical surface active agents were studied.The outcome mentioned above will be active in the fields of matching the relative parameters in ultrasonic cleaning and developing new ultrasonic technology and new non-ODS detergent. They will contribute to protect the ozonesphere above the South Pole and to improve the quality and the competitiveness of the relative production of our country.

主要研究超声空化效应和空化强度测量技术，大功率超声参量对表面活性剂物理化学参量和常用工业洗涤剂性能参量的影响，寻求相关性能参量之间的最佳匹配关系，为高效新型非ODS超声清洗技术和洗涤剂的研制开发提供科学依据。.
