Marine paint antifouling agent DCOIT Preservatives
When a ship sails on the ocean, the parts in contact with seawater are not only strongly corroded by seawater, but also fouled by marine organisms. Seawater is a very strong corrosive medium for steel materials, and many marine organisms and microorganisms can It is adsorbed on the surface of ship bottom, propeller, ship pipeline and other metal structures and grows and reproduces. Especially in warm seas and spring and summer, these harmful organisms grow and multiply rapidly, and the pollution is particularly serious. These marine organisms and microorganisms can destroy the corrosion protection layer of the hull surface and cause the paint film of the hull to fall off; adsorb on the bottom of the ship and the surface of the propeller. The resistance of the ship is increased, and the fuel consumption is increased; the adsorption in the ship's pipeline causes the blockage of the pipeline, and some attached organisms themselves have a corrosive effect on the metal.
Sea water and microbial corrosion reduce the service life of ships, increase maintenance and repair costs, and seriously endanger the safety of ships. Therefore, taking appropriate measures to prevent seawater corrosion and marine organism fouling can effectively reduce and inhibit the corrosion of ships, and greatly improve the economy of ship operations, which has important economic significance and practical value.
Our company launched DCOIT Preservatives, which can effectively inhibit or kill green algae. The inhibiting and killing effects of barnacles are also obvious. They can be widely used in paints, coatings, polyethylene, marine paints and other fields. It can replace the poisonous organic arsenic and other compounds.
