A kind of stirring tank antirust method

Abstract

The invention discloses an antirust method for a stirring kettle. Firstly, the inner wall of the reaction kettle is cleaned with clean water, and after cleaning, air-dried, and then the reaction kettle is further dried with a slight fire to ensure that the reaction kettle does not contain liquid or water vapor. After drying, coat a layer of silica gel on the wall of the reaction kettle. The silica gel has the characteristics of large moisture absorption and small volume expansion, so as to prevent the reaction kettle from being corroded by moisture. In addition, take an appropriate amount of anhydrous copper sulfate, which is a white crystal, grind it, and sprinkle it on the thin sponge pad, and the copper sulfate powder will be in the gaps in the thin sponge pad. The sponge pad also has a certain ability to absorb moisture. When the sponge pad turns blue, it means that the anhydrous copper sulfate turns blue when it meets water, and moisture has entered the sponge pad. So the anhydrous copper sulfate in the sponge pad is used to indicate whether the reactor is damp. Spread a thin sponge pad on the reactor, then cover the outer layer with a plastic film and seal it to ensure that the reactor is separated from the outside world and avoid moisture, thus completing the moisture-proof and rust-proof work of the reactor.

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
