Ship Coating

- Mar 29, 2021-

The marine environment is a very harsh corrosive environment. Ships have been in such a marine environment for a long time, and the corrosion is extremely serious, and coatings have always been the most important means of anti-corrosion.

Marine anti-corrosion and anti-fouling coatings form the basis of marine coatings. According to the use environment and requirements of various facilities, various series of products have been derived, such as marine coatings, heavy-duty anti-corrosion coatings for marine engineering facilities, etc. Among them, the ship coating fork is divided into special coatings such as bottom anti-corrosion and anti-fouling paint, hull paint, deck paint, interior paint, and damping noise reduction. Due to the particularity of cabins, people are not only concerned about the corrosion resistance of cabin coatings, but also their toxicity. Because the corrosion resistance of the coating affects the service time and service performance of the ship, and the toxicity of the coating is related to the personal health and safety of the crew. For this reason, while paying attention to the anti-corrosion, water-based and high-solid differentiation of marine coatings, a more comprehensive overview of the safety, anti-corrosion and long-term effectiveness of cabin coatings is made here. Ships will be attached to fouling organisms while they are sailing.

Traditional antifouling coatings for ships mostly use toxic antifouling agents (tin, copper, etc.) to kill attached organisms in order to prevent biofouling. After this toxic antifouling agent enters the marine environment, it is stable and difficult to decompose. It will eventually enter the human body along the food chain and destroy the ecological balance. Organotin antifouling coatings, which have been widely used in the past few decades, have been banned by the International Maritime Organization. People are also aware of the negative effects of cuprous oxide and other similar fungicides, and will eventually abandon the use of such antifouling agents.

In view of this, the research and development of new non-toxic long-lasting anti-fouling coating materials for ships is imminent. New antifouling coatings are also called environmentally friendly antifouling coatings, which mainly include low surface energy antifouling coatings, tin-free self-polishing antifouling coatings, bionic coatings, conductive polymer coatings, silicate antifouling coatings, etc. Because they are non-toxic and non-polluting, they have attracted the attention of researchers from various countries.

At the same time, fires have always been one of the frequent incidents of ships. According to the survey of the International Maritime Disaster Rescue Association, the proportion of maritime accidents caused by ship fires and explosions in various countries has increased year by year, with an average annual increase of 1%. The average annual tonnage of ships is The loss is more than 600,000 tons. In order to reduce the hazards caused by ship fires and protect the safety of people's lives and property, relevant departments and shipping companies have made continuous efforts over the years to improve ship fire-fighting facilities and use a variety of new fire-resistant materials to protect ships from fire.

In recent years, many research institutions in my country have also conducted exploratory research on anti-fouling and drag-reducing coatings that imitate the epidermis of large marine organisms. It was discovered that China Cybutryne CAS 28159-98-0 is a triazine herbicide, which is more and more widely used in ship hull antifouling coatings.
