| 目的 基于Box-Behnken设计和响应面分析，借助表面形貌表征和污损面积占比分析，通过方程拟合和试验验证，探究了超声时间、功率和频率对光学材料聚甲基丙烯酸甲酯(PMMA)表面海洋微观生物污损防除的影响，为超声防污技术在海洋光学仪器水下窗口微观生物污损防除的应用上提供一定的理论依据和数据支撑。方法 以天然海水为介质，采用动态培养的方法构建PMMA表面微观污损，借助激光共聚焦显微镜(CLSM)，综合单因素实验和三因素三水平Box-Behnken设计，考察超声时间、超声功率、超声频率对超声防除PMMA表面微观污损的影响规律，通过响应面分析获取超声频率、超声时间、超声功率之间的超声防污交互作用，建立超声参数对防污效果的回归方程，最后结合实际工况给出具有最佳污损防除效果的超声工作参数。结果 防污效果随超声频率的增加而降低，随超声功率和超声时间的增加而提高。相对超声功率和超声时间，超声频率对PMMA表面微观污损防除的影响更显著。回归方程能够很好地预测不同超声参数下的防污效果，可用于不同污损情况下超声工况的选择设计。当超声时间为5 min、超声功率为40 W、超声频率为40 kHz时，海水动态培养96 h后，PMMA表面的微观污损超声防污效果可达到98.63%以上。结论 基于响应面分析技术，建立超声参数对超声防污效果的回归方程，有助于选择合适的超声工况，从而使超声防污技术应用于海洋光学仪器水下窗口表面的微观生物污损防除。 |

| This paper aims to investigate the effects of ultrasonic duration, power and frequency on the removal of marine microfouling on polymethyl methacrylate (PMMA) surface on the basis of Box-Behnken design and response surface analysis, by analyzing surface morphology characterization and fouling area ratio, and through the fitting equation and experimental verification, thus providing some theoretical and experimental data supports for the application of ultrasonic antifouling technology in microfouling control of underwater window in marine optical instruments. During this period, the microfouling on PMMA surface was firstly constructed by dynamic cultivation in natural seawater. Secondly, the effect laws of ultrasonic duration, power and frequency on the removal of microfouling on PMMA surface were investigated by means of the laser confocal microscope (CLSM), and by single factor experiment and three-factor three-level Box-Behnken design. Further, the ultrasonic antifouling interaction among ultrasonic frequency, ultrasonic time and ultrasonic power was obtained by response surface analysis, and the regression equation of ultrasonic parameters on antifouling effect was established. Finally, the optimum ultrasonic parameters applied for removing fouling were given based on the actual working conditions. The results show that with the increase of ultrasonic frequency, the antifouling effect decreases, but increases with the increase of ultrasonic power and ultrasonic duration. Compared with ultrasonic duration and ultrasonic power, ultrasonic frequency has a more significant effect on the microfouling removal of PMMA surface. The regression equation can well predict the antifouling effect under different ultrasonic parameters, so it can be used for the selection and design of ultrasonic working conditions according to practical requirements of optical instruments. When the ultrasound duration is 5 min, ultrasound power is 40 W and ultrasound frequency is 40 kHz, the antifouling effect on the PMMA surface can reach to 98.63% after the seawater dynamic cultivation for 96 h. Therefore, it is concluded that, the regression equation of ultrasonic parameters on ultrasonic antifouling effect is established base on response surface analysis, which is helpful to the selection of the suitable ultrasound conditions, thus making the ultrasonic antifouling technology applied in the removal of microfouling on the surface of underwater windows of marine optical instruments. |
