Embodiment 1

[0015] A type cleaning agent for removing organic matter and grease. Its component content is: 1% of disproportionated rosin potassium soap, 1% of sodium carbonate, and 0.002% of organic silicon defoamer (solid content: 30%).

[0016] Use 15% disproportionated rosin potassium soap aqueous solution to prepare, 15% disproportionated rosin potassium soap aqueous solution, boiling point: 102°C (15%); specific gravity: 1.294 (15%) at 20°C; viscosity: 5 at 30°C Centipoise (15%); pH: 9-10 (15% aqueous solution) at 25°C.

[0017] The preparation method is: first dilute 15% disproportionated rosin potassium soap into 1% disproportionated rosin potassium soap solution, then add sodium carbonate to make its concentration reach 1%, add simethicone defoamer (solid content 30% ) to make its concentration reach 0.002%, mix thoroughly and evenly, and quickly seal it for use.

Embodiment 2

[0019] A type cleaning agent for removing organic matter and grease. Its component content is: 5% disproportionated rosin potassium soap, 2% sodium carbonate, and 0.007% organic silicon defoamer (solid content: 30%).

[0020] The preparation method is: first dilute 15% disproportionated rosin potassium soap into 5% disproportionated rosin potassium soap solution, then add sodium carbonate to make its concentration reach 2%, add simethicone defoamer (solid content 30% ) to make its concentration reach 0.007%, mix well and seal quickly for use.

Embodiment 3

[0022] A type cleaning agent for removing organic matter and grease. Its component content is: 12% of disproportionated rosin potassium soap, 10% of sodium carbonate, and 0.01% of organic silicon defoamer (solid content: 30%).

[0023] The preparation method is: first dilute 15% disproportionated rosin potassium soap into 12% disproportionated rosin potassium soap solution, then add sodium carbonate to make its concentration reach 5%, add simethicone defoamer (solid content 30% ) to make its concentration reach 0.01%, mix thoroughly and evenly, and quickly seal it for use.

Abstract

The present invention relates to cleaning agent for removing oil materials and organic materials. The components include that disproportionated rosin potassium soap is 2 to 5 percent, sodium carbonate is 1 to 2 percent, organic silica antifoam agent is 0.002 to 0.007 percent, and others are water. The cleaning agent provided by the present invention has the advantages that the source of the raw material is convenient, the operation is simple, the cost is low, etc., and the cleaning agent is especially suitable for cleaning the organic materials and the oil stain of the inner wall of the industrial equipment, the pipeline of the drainage system or the pipe wall of the culvert.

Description

technical field [0001] The invention relates to a cleaning agent, especially a cleaning agent for cleaning equipment and pipe walls polluted by oil and organic substances, especially a cleaning agent suitable for cleaning the inner walls of equipment and pipelines with a large amount of organic substances and oily substances. Pipe wall cleaning agent. Background technique [0002] "Water Treatment Technology and Pharmacy Encyclopedia" (Sinopec Press, 2002, June) edited by Chen Fu introduced that commonly used alkaline cleaning agents are sodium hydroxide, sodium carbonate, disodium hydrogen phosphate and sodium silicate. Since this type of cleaning agent is alkaline, it can loosen, emulsify, and disperse the deposits in the equipment. Generally, surfactants are added to this type of alkaline cleaning agent to wet the deposits (such as grease, dirt and microorganisms, etc.) to improve the cleaning effect. [0003] CN1420162A discloses an ozone water type multifunctional sca...
