Problems solved by technology

[0003] At present, equipment and facilities used in industrial wet desulfurization and denitrification methods mainly include GGH heat pipes, desulfurization towers, gas pipes, flues and chimneys, and anti-corrosion materials and methods mainly include lining epoxy (phenolic epoxy, epoxy furan, vinyl ester and other resins) FRP layer, or use epoxy or vinyl ester resin glass flake cement and paint, vitrified bricks, etc. for anti-corrosion protection, but the protective effect is not ideal
In the short period of three to five months, and in the elderly for a year or so, the protective layer will be corroded and peeled off, not only losing its protective effect, but also causing the flue to be blocked due to the accumulation of peeling off. Some use vinyl ester glass flake cement, and even lead to damage on the construction site. Deflagration, a large-scale fire broke out, and the entire desulfurization tower, flue and chimney were burned and scrapped, causing significant loss of life and property

Abstract

The invention provides environment-friendly titanium-based polymer alloy anti-corrosion daub. The daub comprises solvent-free titanium-based polymer alloy anti-corrosion daub and water-soluble titanium-based polymer alloy anti-corrosion daub, belonging to the technical field of novel anti-corrosion materials. The environment-friendly titanium-based polymer alloy anti-corrosion daub consists of a titanium-based polymer alloy copolymer, an auxiliary film-forming matter, an anti-corrosion and wear-resistant filler, a chemical additive, a reactive diluent or purified water and an independent curing agent, and has the characteristics of strong adhesive force, temperature change resistance, wear resistance, corrosion resistance, no pulverization, no cracking and no shedding; construction is easy and convenient, no toxicity or odor exists, flammable and explosive risks do not exist, and safety and environment friendliness are achieved; compared with glass fiber reinforced plastics, layer-by-layer cloth sticking is not needed for the daub; and compared with a vitrified brick, seamless connection and overall protection are achieved, and particularly, acid corrosion in a high-temperature-resistant environment is achieved, and the economic life exceeds 5 years.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion new materials, and relates to an environment-friendly titanium-based high-molecular alloy anti-corrosion cement, including a solvent-free titanium-based high-molecular alloy anti-corrosion cement and a water-soluble titanium-based high-molecular alloy anti-corrosion cement. Background technique [0002] There are currently two methods for industrial flue gas desulfurization and denitrification technology: one is the liquid ammonia desulfurization and denitrification method used in the coal chemical industry, and the other is the calcium oxide desulfurization and denitrification method used in the petrochemical, thermoelectric, and metallurgical industries. These two methods belong to wet desulfurization and denitrification. The resulting high-temperature acidic corrosion environment has a huge impact on the corrosion hazards and economic losses of equipment and facilities. Tens of millions o...
