Epoxy Resin Is Dense, Water-resistant And Anti-leakage

As an anti-corrosion material, epoxy resin not only has the characteristics of compactness, water resistance, good leakage resistance and high strength, but also has good manufacturability such as strong adhesion, normal temperature operation, and simple construction, and the price is moderate. Anti-corrosion projects using such materials generally include: the overall surface layer and isolation layer of FRP lined with resin glue, the block surface layer paved with resin cement and mortar, the block surface layer of resin cement jointing and grouting, resin Single and composite overall surface and isolation layer made of thin cement or mortar, resin glass flake cement surface, etc. Depending on the variety of materials selected, the final product function and scope of application of anti-corrosion engineering will be very different. Experts said that the epoxy resin commonly used in anti-corrosion engineering can be used in combination with resins such as unsaturated polyester resin, vinyl ester resin, phenolic resin and furan resin to form a composite structure to give full play to their respective properties. Advantages, reduce costs, improve product quality, and facilitate construction. It can also be modified with other resins to form modified resins, and the modification methods include physical methods and chemical methods. Epoxidized coal tar is a typical physical modification product of epoxy resin, and its performance is between epoxy resin and coal tar. The secondary resin in the physical modified resin generally accounts for 30 to 50% of the total; after the resin is chemically modified, the properties of the product have undergone fundamental changes, and the vinyl ester resin is essentially the most typical epoxy chemically modified resin. Sometimes two or more resin materials with better comprehensive properties are used. According to their respective characteristics, different structures of different parts of the project are unified in different parts of the project. Constructing in sequence can produce remarkable effects that are difficult to achieve with a single material.
