Abstract

The invention relates to a degradable environment-friendly dirt remover which is characterized by comprising the following components in percentage by weight: 70-75% of citric acid, 14-18% of sulfamic acid, 5.0-6.0% of sodium gluconate, 2.8-3.0% of sodium polyaspartate, 1.4-1.6% of thiocarbamide and 1.4-1.6% of 2,2-dibromo-3-nitrilopropionamide. In the invention, environment-friendly solid organic acids are used as the main components, and degradable corrosion inhibitor, dispersant, slime remover and chelator are used as auxiliary components, therefore, the degradable environment-friendly dirt remover is applicable to various types of dirt and various metal materials, and has excellent descaling and corrosion-inhibiting properties. The degradation rate of the degradable environment-friendly dirt remover can be higher than 93% after 28 days, thus, the degradable environment-friendly dirt remover belongs to an environment-friendly product. The product can be used for preferably overcoming the defects of single function, narrow applicability and non-environment-friendliness in the current cleaning agent.

Description

technical field [0001] The invention relates to a degradable and environment-friendly fouling stripper for removing the scale and embroidery scale formed in a heat exchange system. Background technique [0002] In almost all industrial and civil fields such as chemical industry, pharmacy, fertilizer, electric power, printing and dyeing, iron and steel, metallurgy, heating and civil use, after a period of operation of many equipment, a large amount of scale or other types of scale will form on some heat exchange parts. dirt. The formation of these dirts, in the light of cases, will cause the working efficiency of the equipment to drop, shorten the service life of the equipment, increase energy consumption and production costs, and in the severe cases, it may lead to the scrapping of the equipment, production accidents or environmental pollution and other serious consequences, and the economic losses will be huge. Therefore, these devices must be chemically cleaned after a pe...
