    The attachment of marine deposits of paint, and suitable living environment-temperature, salinity seawater pH 7 ~ 8, rich nourishment prompted the fouling organisms rapid growth and reproduction, for example, barnacle larvae within 48 hours of a sticky secretion by suckers have glair curing nitration Holy, and its adhesion strength manages 5 nautical miles/h sea water erosion.
    Whereas the diatoms in sea water and various fouling organisms larvae of more than most people might think coatings, so far what attachment order is microbial-animals-plant-or other order is not known, tracking of barnacles mechanism more than half a century and a lot of problems has not yet been resolved, but the main factors affecting the attachment initially fouling organisms summarized some of the types and numbers with sea-level changes in the ecological environment change the same Bay because of the season, biological variation, such as marine pollution levels could of salt content in different between change attachment table anticorrosion coating surface are different in nature, and its attachments are also different adhesion surface properties including, surface roughness, test to prove detrimental to the smooth surface of the attachment of our departure from the requirements of% rent reduction also need the roughness of the surface as low as possible, surface tension.
    Detrimental to the attachment, which is non-toxic low surface energy development-repellent coatings and paint exhibits, rigid and modulus of elasticity and concentration of the existence of the prevention of pollution Agent prevents attachment, which is why antifouling coatings and electrolytic design fundamentals of anti-fouling method, water flow velocity, also have an impact, it is generally believed when the water flow velocity is greater than 5 nautical miles/h fouling organisms cannot be attached at the bottom of the boat, which means that there is no biological under normal speed, in other words one time, such as 48h for the navigation of the attachment of light on f-from attachment to ground the harm to the marine facilities via the test to prove in Qingdao Sino-Hong Kong a growth of our busy season 6 ~ October per square meter to fouling organisms > 20 kg, power station cooling water pipeline in each of the loss of 100 mm diameter 50 ~ there are data suggests million tones of ocean-going round, its bottom defaced 5% fuel consumption will increase by Oh 10% in each of the loss of over US $ 1 million, not being a ship of speed is the foundation of mobility and fighting power, sonar cover of anti-fouling ensures it to be functional, it is also vital.
