Cleaning agent for cleaning dirt on printing and dyeing rotary drums and application of cleaning agent

Abstract

The invention discloses a cleaning agent for cleaning dirt on printing and dyeing rotary drums and application of the cleaning agent. The cleaning agent in a formula comprises, by weight, 5-12 parts of oxygen acid, 0.2-1 part of potassium rhodanide, 2-4 parts of acetic acid, 2-4 parts of nitric acid, 2-4 parts of iron chloride, 0.1-0.8 part of permeating agents, 0.2-1 part of corrosion inhibitors,0.1-0.5 part of aniline, 0.1-0.6 part of emulsifiers and 100-150 parts of water. The mass fraction of the nitric acid is 3-5%. The cleaning agent and the application have the advantages that different types of oxygen acid jointly cooperate with the corrosion inhibitors, the permeating agents and the emulsifiers in the cleaning agent, and accordingly unique permeation, peeling, decomposition and diffusion effects and the like can be realized; decomposition and combination chemical reaction and the like in different forms can be carried out on the cleaning agent and the dirt, and accordingly the purpose of clearing the dirt without damage on the surfaces of equipment can be ultimately achieved by the cleaning agent.

Description

Technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent for cleaning dirt on a printing and dyeing cylinder and its application. Background technique [0002] The surface of the printing and dyeing drums, drying drums, and dyeing and pulping machine drums often used in the textile printing and dyeing industry often adheres to a large amount of dirt. In addition to carbonates and silicates, these dirts also contain a large amount of heavy metal elements and Various dye components are not only complex, but also hard and difficult to remove. [0003] The chemical properties of sulfuric acid are very active. It can react with all metals and their oxides and hydroxides to form sulfates at room temperature, destroying the molecular structure of the elements that make up the dirt. However, due to the poor water solubility of sulfate produced by sulfuric acid descaling, the descaling effect when sulfuric acid is used alone is not ideal. [0004] ...

AI Technical Summary

Problems solved by technology

However, due to the poor solubility of the sulfate salt produced by sulfuric acid descaling, the descaling effect is not ideal when sulfuric acid is used alone

[0004] Acetic acid is an oxygen-containing acid widely used in the chemical cleaning process. It has the characteristics of low cost, simple operation, fast scale dissolution and good surface condition of equipment after cleaning. It can chemically react with calcium and magnesium salts at room temperature to form soluble Chloride, but ineffective against silicate scale

[0005] Most of the existing cleaning agents can only remove light dirt, and the descaling effect on heavy dirt is not ideal

The traditional method can only use manual methods such as beating and scraping to remove heavy dirt, which is not only time-consuming and laborious, but also easily damages the equipment and causes losses to the enterprise
