Rust protection method for agitator kettle

Abstract

The invention discloses a rust protection method for an agitator kettle. The inner wall of the reaction kettle is firstly cleaned with clear water, air drying is carried out after cleaning, and then the reaction kettle is further dried with low fire, so that it is ensured that no liquid or moisture is contained in the reaction kettle. After drying, the wall of the reaction kettle is coated with a layer of silica gel, and silica gel has the beneficial effects of being high in absorbed humidity amount and small in volume expansion, so that the reaction kettle is prevented from being affected with damp and corroded. In addition, an appropriate amount of anhydrous cupric sulfate which is white crystal is taken to be ground and then scattered on a thin sponge mat, and copper sulfate powder can be located in clearances in the thin sponge mat. The sponge mat has certain moisture absorption capacity, and when the sponge mat becomes blue, it is shown that anhydrous cupric sulfate becomes blue when encountering water, and moisture enters the sponge mat. Therefore, anhydrous cupric sulfate in the sponge mat is used for indicating whether the reaction kettle is affected with damp or not. The thin sponge mat is laid on the reaction kettle, then the outer layer is covered with a plastic film and sealed, so that it is ensured that the reaction kettle is isolated from the outside and prevented from being affected with damp, and the work of damp prevention and rust prevention of the reaction kettle is achieved.

Description

technical field [0001] The invention relates to the field of steel rust prevention and equipment maintenance in the chemical industry, in particular to a rust prevention method for a stirred tank. Background technique [0002] With the development of my country's metallurgical industry. The types, specifications and quantities of steel products used in construction projects have increased rapidly, the quality and performance have been steadily improved, and the application of steel structure technology has become increasingly widespread. Because the steel structure is easy to rust. Therefore, antirust of steel structure has become an indispensable and important part of steel structure engineering. With the advancement of technology and the development of science and technology. There are more and more antirust measures for steel structures. The construction techniques are also different. Depending on the form of the steel structure and the surrounding environment, diffe...

Problems solved by technology

Cleaning agent with low critical concentration, it forms micelles in a dilute solution, so under the same use ratio conditions, there are more parts to be washed with low critical concentration, and the service life is long

[0012] 2. The cloud point is high or low

The hydrophilicity is weakened, the solution is turbid, the surface activity is reduced, and the cleaning ability is reduced
