preparation example Construction

[0029] A preparation method of high-efficiency environmentally friendly color tracer acid cleaning agent, including the following steps:

[0030] Step 1. Take the deionized water according to a certain mass ratio, add it to the chemical material kettle, and then sequentially add the compound acid according to a certain mass ratio to obtain a mixed solution A;

[0031] Step 2. Add a chelating agent to the mixed solution A according to a certain mass ratio to obtain a mixed solution B;

[0032] Step 3. Add the surfactant in the mixed solution B according to a certain mass ratio and stir evenly to obtain the mixed solution C;

[0033] Step 4. Add a corrosion inhibitor to the mixed solution C according to a certain mass ratio, and stir evenly to obtain a mixed solution D;

[0034] Step 5. Add an indicator to the mixed solution D according to a certain mass ratio, and stir evenly to obtain a mixed solution E;

[0035] Step 6. Filtering the mixed solution E to obtain the solvent-free high-effi...

Embodiment 1

[0037] A high-efficiency and environmentally friendly color tracer acid cleaning agent, including the following components and mass parts:

[0038] 15 parts of citric acid, 9 parts of p-tert-butyl benzoic acid, 6 parts of oxalic acid, 5 parts of 0810 carbon APG, 20 parts of EDTA-3Na, 1.5 parts of methyl red 0.1% alcohol solution, 2.5 parts of thiourea, cationic imidazoline corrosion inhibition 2.5 parts of deionized water and 38.5 parts of deionized water;

[0039] When the product of the present invention is used for cleaning, the entire industrial circulating cooling water system is cleaned, and water is added from 1:30 to 50 according to the scale of the scale; the entire chilled water system is cleaned with water from 1:100 to 1:150. In order to prevent the medicine from reacting too fast and blocking the system, you can add the medicine 3-4 times at 30 minutes intervals. If the medicine is added again, the medicine solution turns red, indicating that it has been cleaned.

Embodiment 2

[0041] A high-efficiency and environmentally friendly color tracer acid cleaning agent, including the following components and mass parts:

[0042] 15 parts of citric acid, 9 parts of p-tert-butyl benzoic acid, 6 parts of oxalic acid, 2 parts of surfactants, 5 parts of tetrasodium glutamate, 0.5 parts of methyl red 0.1% alcohol solution, 1 part of thiourea, cationic imidazole 1 part of morpholine corrosion inhibitor and 60.5 parts of deionized water.

[0043] When the product of the present invention is used for cleaning, the central air-conditioning host is cleaned, and the water is mixed with 1:20 to 30 times according to the scale of the scale; the first time it is added, the drain will be yellow or other colors. In order to prevent the syrup from reacting too fast and blocking the system, the syrup can be added 3-4 times in 30 minutes. If the medicine is added again, the medicine liquid turns red, indicating that it has been cleaned.

Abstract

The invention discloses a high-efficiency environment-friendly colored tracing acidic cleaning agent, and relates to the technical field of cleaning agents. The cleaning agent comprises the componentsin parts by weight: 20-50 parts of compound acid, 2-10 parts of a surfactant, 5-20 parts of a chelating agent, 0.5-1.5 parts of an indicator, 2-5 parts of a compound corrosion inhibitor and 28.5-60.5parts of deionized water. The prepared cleaning agent is efficient in cleaning, green and environmentally friendly and capable of achieving colored tracing, a user can judge a cleaning end point conveniently and discharge an acidic cleaning liquid out of a system in time, energy is saved, and corrosion of excessive pickling to equipment is effectively avoided; and meanwhile, carbonate scale, sulfate scale, rust scale, sediments of other minerals and silt deposits can be safely, effectively and quickly removed.

Description

Technical field [0001] The invention belongs to the technical field of cleaning agents, and particularly relates to a high-efficiency environmentally friendly color tracer acid cleaning agent. Background technique [0002] At present, domestic acid chemical cleaning agents for central air conditioning circulating water systems and industrial circulating cooling water systems mainly use hydrochloric acid, sulfuric acid, nitric acid, and ammonium bifluoride. Most of these acids have a strong pungent odor and are highly corrosive, which poses safety risks to equipment and operators. Secondly, the commonly used acid cleaning agents can only be used to remove a certain type of scale layer, and the cleaning effect of the system is not obvious for the scale layer composed of multiple components. In addition, it is generally inconvenient to judge the end point of the pickling process. In order to clean thoroughly, an excessive amount of pickling liquid is often used and circulated in th...
