Abstract

The invention discloses a carbene environment-friendly descaling derusting anticorrosion antirust liquid and a preparation method and application thereof. The carbene environment-friendly descaling derusting anticorrosion antirust liquid is made from, by mass, 1-10% of carbene, 0.1-1.0% of an accelerant, 0.01-1.00% of a dispersant, and the balance of deionized water. Carbene is water-soluble carbene sol, having pH of 0.5-3, electromotive force E of 280-380 mv, particle size phi of 0.3-20 nm, particle size distribution psi of D90-D98, and solute content of 0.1-1%. The carbene environment-friendly descaling derusting anticorrosion antirust liquid has an efficient quick penetration function and a corrosion inhibition function, allows water scale and rust on the metal wall to be washed and removed within a short time, can protect the base metal and impart a corrosion-inhibiting film coating to the base metal, can provide improved corrosion resistance for a material, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an environment-friendly descaling, rust-removing and anti-corrosion solution for treating the surface of metal materials and metal products. Background technique [0002] The descaling, rust, and corrosion prevention of metal surfaces has always been concerned as a technical problem. The heat exchange device with water as the cooling medium will scale in the system after a period of use and form on the wall of the container or pipe, such as the inner wall of the tube of various heat exchangers. The main components of scale are calcium carbonate and magnesium carbonate. At the same time, metal surfaces are prone to oxides, that is, metal corrosion and rust stains. Deposited scale and rust affect heat exchange efficiency. For example, when the fouling reaches a thickness of 0.5mm, it will make the heat exchanger cooling system unable to transfer temperature norma...
