摘要

由于生物膜的形成，印度各地的船只面临着严重的问题。无论是木质船体还是玻璃钢船体，由于藻类、细菌和其他微生物的积累，生物膜是不可避免的。这最终导致第二阶段藤壶和海草的积累，造成严重的生物污染。由于阻力(相对于流体摩擦)和整体效率，生物污染的船或船面临严重的速度下降。因此，本研究对聚四氟乙烯和环氧树脂等一系列生物膜涂层进行了研究，并进行了相应的污染研究。同时,混合有机农药的影响以及防污剂也进行了研究。实验研究表明:一是不同水样在3个不同阶段(对数、平稳和下降状态)对生物污染因子的影响;二是环氧涂料与有机农药(印楝)的体积分数混合，可以有效地减少船体的生物污染。

Experimental Investigation and Study of Bio Fouling in Marine Applications

Shipping vessels/ships across India face serious issues due to biofilm formation. Irrespective of wooden or FRP boat hulls, biofilms are inevitable due to accumulation of algae, bacteria and other microorganisms. This eventually leads to the accumulation of barnacles and sea weeds in second phase which causes serious bio-fouling. Bio-fouled boats or ships face serious decline in speed due to drag force (respective of the fluid friction) and overall efficiency too. Hence in this study, a series of bio-film coatings such as Teflon and epoxy are performed and corresponding fouling studies are done. Also, the effects of blending organic pesticide along with anti-fouling agents are also studied. Experimental investigation shows that two major benefits, first one is about the performance of bio-fouling factors observed with different water samples in 3 different stages (Log, stationary and declined condition) and second is about epoxy coating blended with organic pesticide (Azadirachta Indica) volume fraction is effective in reducing bio fouling in boat hulls.

期刊介绍： Periodico di Mineralogia is an international peer-reviewed Open Access journal publishing Research Articles, Letters and Reviews in Mineralogy, Crystallography, Geochemistry, Ore Deposits, Petrology, Volcanology and applied topics on Environment, Archaeometry and Cultural Heritage. The journal aims at encouraging scientists to publish their experimental and theoretical results in as much detail as possible. Accordingly, there is no restriction on article length. Additional data may be hosted on the web sites as Supplementary Information. The journal does not have article submission and processing charges. Colour is free of charges both on line and printed and no Open Access fees are requested. Short publication time is assured. Periodico di Mineralogia is property of Sapienza Università di Roma and is published, both online and printed, three times a year.
