For a long time, anti-corrosion coatings have been widely used in various fields of the national economy as a simple, economic, and effective anti-corrosion measure. The use of simpler and more economical heavy anti-corrosion coatings has been widely applied and developed rapidly in many fields both at home and abroad in recent years. Let's take a look at it below.
Heavy-duty coating formulations
Epoxy 30%, polyurethane 20%, zinc-rich primer 16%, alkyd 14%, acrylic chlorinated rubber 13%, fluorocarbon 4%, polysiloxane 1%, other %.
The role of heavy anti-corrosion coating
First, the protective effect
Metals, wood, and other materials are often exposed to the atmosphere and are gradually destroyed by the erosion of atmospheric moisture, salt fog, gases, and microorganisms. Coating the surface of the object can block the corrosive medium from the outside, prevent corrosion and prolong the service life.
Second, the decorative effect
The paint has the characteristics of bright, beautiful, bright and beautiful, bright color, etc. It can change the original color of objects, harmonize colors, improve the environment and beautify life. In defense, the protective color of paint is also used as a camouflage covert effect.
Third, the role of the logo
The color of various chemicals, dangerous goods, etc. that can be used in various factories is used as a symbol. The various pipes, mechanical equipment, and signal devices on the ship are coated with various colors of paint as a mark, which allows the operator to easily identify and operate. Traffic lines use different colors of paint to signal warnings, dangers, etc.
Fourth, the special role
Insulating coatings can provide insulation in the electrical industry; anti-fouling coatings can kill or disperse sea creatures attached to the bottom of the ship; some coatings also have special protections such as non-slip, oil resistance and so on.
The role of the paint is usually achieved through a matching coating (such as anti-corrosion paint) or a single coating (powder paint).
Heavy anti-corrosion coating standard
The important sign of the heavy anti-corrosion coating standard is thick film formation. Compared to conventional anti-corrosion coatings from 100 μm to 150 μm, the heavy-duty anti-corrosion coatings have a dry film thickness of 200 μm or more and even some special coatings have an amazing dry film thickness of 2000 μm ( 2mm). The thick anti-corrosion coating provides a reliable guarantee for the long-term life of the coating.
In order to achieve long-lasting anti-corrosion purposes, there are high requirements for the main film-forming substance synthetic resin. First, because of the special nature of the coating industry, the synthetic resin must have good adhesion to the matrix, and it also needs to have a variety of media. Has excellent corrosion resistance, such as chemical atmosphere, salt, alkali and other solvents. For example, epoxy resins used in ordinary anti-corrosion coatings have problems such as poor weather resistance and easy powdering. Heavy-duty coatings for chemical atmospheres in heavy anti-corrosion coatings are modified by adding chlorosulfonated polyethylene rubber and other ingredients. The method, and according to different corrosion environment requirements, will be improved to epoxy heavy anti-corrosion coating products.
Heavy anti-corrosion coating product features
1 It can be used under harsh conditions and has a long-lasting corrosion-resistance life. Heavy-duty coatings can generally be used in chemical atmospheres and marine environments for 10 years or more, even in acid, alkali, salt and solvent media, and in Under certain temperature conditions, it can also be used for more than 5 years.
2 Thick film is an important symbol of heavy-duty coatings. The dry film thickness of the general anti-corrosion coating is about 100 μm or 150 μm, while the dry film thickness of the heavy anti-corrosion coating is 200 μm or 300 μm or more, 500 μm to 1000 μm, or even up to 2000 μm.
