Epoxy anti corrosion coatings are usually composed of epoxy resin and curing agent. The nature of the curing agent also affects the performance of the paint film. Commonly used curing agents are: aliphatic amines and their modified products, which are characterized by being cured at room temperature, unmodified aliphatic amines are more toxic, and aromatic amines and their modified products, which are characterized by slow reaction, often require heating to cure, and are more toxic Weak, perchlorovinyl paint, polyamide resin, characterized by good weather resistance, less toxicity, good elasticity, and slightly poorer corrosion resistance. Other synthetic resins such as phenolic resin and urea-formaldehyde resin.
Grease paint is a type of paint with drying oil as the main film-forming material. It is characterized by easy production, good paintability, good wettability to the surface, low price, flexible paint film, but the paint film dries slowly, the film is soft, the mechanical properties are poor, acid and alkali resistance, water resistance and resistance Poor organic solvent properties. Dry oil is often combined with anti-rust pigments to form anti-rust paint. It is used in atmospheric environments where corrosion resistance is not required. Raw lacquer, also known as national lacquer or large lacquer, is one of my country's specialty products.
According to the principle of electrochemical corrosion, the corrosion of steel must have the presence of oxygen, water and ions, as well as the passage of ions to conduct electricity. The paint film prevents the existence of corrosive media and the surface of the material, and the passage of the corrosive battery increases the resistance. , The penetration rate of oxygen and ions to the paint film is different. The penetration rate of water is much higher than that of ions and oxygen. It is straightforward to penetrate the paint film less, so it is not necessary to consider their direct effect on the substrate metal.
The sealant has a fine texture and no bubbles, and the taste is very small. It is very convenient to use and dries very fast. The instructions are very detailed. The effect is good after using it.
The packaging of this product is very good, very strict, and the design is very scientific.
The product I bought is really good. The other ones I bought before have a lot of particles in it. They are not smooth to the touch. I don’t know how to use it, and the beauty stitches I bought make it. I really don’t have to say.
The effect is very good! The smell is very small, almost no smell during construction.
The quality is very good. I made it at home by myself. It's okay. The effect is good. The quality is indeed better than the price bought in other stores.
The smell is very small, the gel is translucent, it is smooth to use, and it dries quickly. The anti-mildew effect needs time to test.
Anti-corrosion coatings mainly include: Chuanxing fluorocarbon anti-corrosion coatings, high-temperature anti-corrosion coatings, asphalt anti-corrosion coatings, heat-resistant anti-corrosion paints, etc. According to their performance, they are divided into epoxy anti-corrosion coatings, grease coating raw lacquer, and modified raw lacquer latex paint.
According to the purpose, it can be divided into: anti-corrosion paint for rubber, anti-corrosion paint for pipeline, anti-corrosion paint for furniture, anti-corrosion paint for ships, anti-corrosion paint for metals, anti-corrosion paint for automobiles;
The anti-corrosion principle of general anti-corrosion coatings lies in chemical and physical Principles of Chemistry The chemical principle of anti-corrosion is to neutralize harmful acid-base substances into neutral and harmless substances to protect the materials in the anti-corrosion coating from corrosive substances. Some amphoteric compounds, such as aluminum hydroxide, barium hydroxide and zinc oxide, are often added to anti-rust coatings. These substances can easily react with acid and alkali harmful substances to achieve anti-corrosion effects. Principles of Physics The physical principle of anti-corrosion is to isolate the protected material from external corrosive substances with an anti-corrosion coating. The physical principle of anti-rust paint is to use a film-forming agent to obtain a dense anti-corrosion coating to isolate the damage of the anti-corrosion effect to the protected material. For example, lead-containing paint and oil can form lead soap to ensure the anti-corrosion coating The density.
