本論文主要目的是透過實驗來探討超疏水性塗料減阻效應、表面微結構耐用性、塗料於水中氣體保存的時間以及防止微生物生成效果,並與現今所用之船用塗料比較,以期能實際應用在船用塗裝等用途上,並達到節能之效果。本文可將實驗分為兩大部分:(1)建立一套於船舶實際航行的速度下能夠有效量測減阻效應的機構,並測試超疏水性減阻塗料的表面微結構的耐用性;(2)透過海拋鋼板的方式,來驗證超疏水性減阻塗料,是否能有效防海中微生物生成。
由實驗結果發現,超疏水性塗料在高流速情況下(紊流)未如原先預測具有減阻效果,原因可能在於塗料表面粗糙度差異。但在流速1m/s以下阻力可能小於台船標準塗料,所以未來超疏水性塗料宜朝表面微結構平整方向進行。在耐用性測試方面發現在高流速情況下,超疏水性塗料表面微結構經過6∼8小時於流速1∼6m/s的實驗之後,並不會因此被破壞。最後在防止微生物生成實驗上,型E超疏水性塗料具有較佳表現。
This study is devoted to investigating the effect of the drag reduction, the sustainability for operations and the effects for preventing microorganism from adhering to the surface when superhydrophobic coating is applied. The experiments are divided into two main parts. In the first part, a pipe flow system was established to measure the drag and to test the sustainability of the micro-structure due to superhydrophobic coating at average speeds varying from 1m/sec to 6m/sec. In the second part, we tested the effect for preventing microorganism from adhering to the surface by putting the coating plate into sea water. There are five different superhydrophobic coatings in our study.
The experimental results show that the drag due to the superhydrophobic coating is higher than that due to the CSBC standard coating when the test speed is higher than 1m/s. This pessimistic result occurs probably because the surface roughness plays an important role in turbulent reisitance. However, the drag is probably lower when the test speed is smaller than 1m/s, according to the extrapolation of resistance curve. Our suggestion is that the development of superhydrophobic coating technique should take into account the surface smoothness of microstructure in the future. In addition, in the sustainability tests, we found that the microstructure appears to keep intact after continuous test 6~8 hours with flow speed varying between 1m/s~6m/s. Finally, the sea test shows that the coating of type E is most capable of preventing microorganism from adhering to the surface.
