Abstract

The invention provides inner wall paint for a temperature-resistant corrosion-resistant chemical pump, and belongs to the technical field of paint. The surface of the inner wall of the pump is coatedwith the corrosion-resistant paint, then the paint is cured, dried and annealed, and the process of coating the surface of the inner wall with the corrosion-resistant paint is completed. After the surface of the chemical pump is coated with the corrosion-resistant paint, a coating capable of blocking corrosion media, air and CO2 from diffusing into steel is formed on the surface of the inner wallof the pump, the coating is effectively protected against oxidization at high temperature, the coating is resistant to chemical corrosion liquid erosion, and then the corrosion and production cost ofthe inner wall of the pump are further reduced. According to the corrosion-resistant paint, the coating on the surface of an inner wall substrate is continuous and compact, the chemical stability is good, the preparation method is simple, energy is saved, environment friendliness is achieved, equipment requirements are low, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a temperature-resistant and corrosion-resistant inner wall coating for chemical pumps. Background technique [0002] Corrosion-resistant pumps are used to transport various corrosive liquids such as acids, alkalis and salts. It is widely used in petroleum, chemical and national defense departments, especially in the chemical industry, so it is also called chemical pump. [0003] Chemical pumps are often corroded by chemical atmosphere or corrosive liquids, and they need to be protected with corrosion-resistant coatings, especially to prevent corrosion of corrosive liquids. Using coatings is the most economical method, so corrosion-resistant coatings are one of the most important materials for chemical pumps. First, correctly mastering their performance and construction methods is a necessary condition for carrying out anti-corrosion work. The corrosion resistance of the paint ...
