Anti- fouling paint is a kind of special paint that prevents the ship from being blocked due to the adhesion of marine organisms when the ship sails in the ocean. During the struggle with marine attached organisms for thousands of years, it has been found that the use of anti-fouling paint to coat the bottom or underwater facilities is the best anti-fouling measure. Anti-fouling paint can keep the water-soaked part smooth and free from dirt. What is the characteristic of anti-fouling paint ? What are the types of antifouling paints ? Let's take a look with Xiaobian.
Antifouling paint features
1. Antifouling paint can prevent the attachment of marine attached organisms within a certain period of time;
2. The toxic material in the paint film steadily leaks out into the seawater;
3, the film has a certain degree of water permeability, to ensure continuous leakage of toxicity;
4, with anti-rust paint has good adhesion and supporting performance, anti-fouling paint itself should also have good interfacial adhesion and can be slightly soluble with anti-rust paint;
5, the paint film must have good resistance to seawater impact, does not blistering, does not fall off when immersed in water for a long time;
6, in the navigation process, there are different degrees of self-polishing ability;
7. Good storage stability, generally 1 year, antifouling performance does not decrease during storage.
Antifouling paint types
At present, there are many kinds of antifouling paints. The main development directions are as follows: 1 Self-polishing antifouling paint without organic tin; 2 Abrasive antifouling paint of Wuxi; 3 Nontoxic antifouling paint (low surface energy paint, biological antifouling Paint, etc.); 4 conductive antifouling paint.
Commercial antifouling paints can be divided into two major categories: 1 Antifouling paints containing insecticides (hydrated self-polishing antifouling paints, hydrolyzed self-polishing antifouling paints, and hybrid self-polishing antifouling paints); 2 No Antifouling paint containing insecticide (or low surface energy antifouling paint, or fouling release antifouling paint FRC).
According to the antifouling paint development and mechanism of action can be roughly divided into the following three categories: traditional antifouling paint, organic tin self-polishing antifouling paint and new antifouling paint.
In order to effectively control the release of antifouling agents, people adopt different technical approaches and adopt a new type, high-efficiency, non-toxic anti-fouling material for ships, which will not cause any adverse impact on the marine ecological environment. Such antifouling paints can be roughly divided into: 1 base material non-solvent antifouling paint (contact and diffusion type); 2 base soluble antifouling paint; 3 new antifouling paint; 4 marine anticorrosion self-polishing antifouling paint.
The above features about antifouling paints and types of antifouling paints are briefly introduced here. We hope to help you. For more information, please visit this website. Stay tuned.
