Cleaning solution for cleaning surface of printing and dyeing equipment

Abstract

The invention discloses a cleaning solution for cleaning the surface of printing and dyeing equipment. The cleaning solution comprises, by weight, 4-16 parts of inorganic acid, 0.2-0.7 part of potassium thiocyanate, 2-4 parts of hydrochloric acid, 2-4 parts of nitric acid, 2-4 parts of hydrogen fluorideammonia, 0.1-0.9 part of penetrant, 0.2-1 part of corrosion inhibitor, 0.1-0.4 part of aniline, 0.1-0.8 part of emulgator, and 100-150 parts of water. According to the cleaning solution for cleaning the surface of the printing and dyeing equipment, multiple kinds of the inorganic acid cooperate with the corrosion inhibitor and the penetrant; special effects such as permeating, stripping, decomposing and diffusing are performed; different chemical reactions such as decomposing and combining are conducted among the inorganic acid, the corrosion inhibitor, the penetrant and dirt; and the purposes that the dirt is cleaned and the surface of the equipment is not damaged are finally achieved.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent for cleaning surface dirt of printing and dyeing equipment. Background technique [0002] The surface of mechanical equipment such as printing and dyeing cylinders, drying cylinders, and dyeing and pulping machine cylinders 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 in composition, but also hard and difficult to remove. [0003] The chemical properties of sulfuric acid are very active. At room temperature, it can react with almost all metals and their oxides and hydroxides to form sulfates, destroying the molecular structure between the elements that make up the dirt. However, due to the poor solubility of the sulfate salt produced by sulfuric acid descaling, the descaling ...

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] Hydrochloric acid is an inorganic 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 easily soluble Chlorides, but ineffective against silicate scales

[0005] Most of the existing surface dirt cleaning agents for printing and dyeing equipment can only remove light dirt, and the descaling effect on heavy dirt is very unsatisfactory

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
