Problems solved by technology

Although traditional cleaning agents have a certain ability to clean dirt, they have little effect on the hard dirt that has been agglomerated. Some cleaning agents need to be treated for a long time to soften the hard dirt, thus prolonging the cleaning time.
In addition, traditional cleaning agents are difficult to achieve the ideal cleaning effect on the workpiece surface with various oil stains

Embodiment 1

[0019] A kind of fast degreasing and descaling cleaning agent of the present invention, its component and weight percentage thereof are:

[0020]

[0021] Dilute the cleaning agent configured above to 5% by weight to obtain a cleaning solution, and use the cleaning solution to clean the workpiece at a temperature of 50°C and a free alkali content of 25 points for 5 minutes.

[0022] The assay method of described free base content comprises the following steps:

[0023] (1) Use a pipette to draw 10ml of the above cleaning solution into a 250ml Erlenmeyer flask, add 2 drops of phenolphthalein with a mass concentration of 1%, shake well, and obtain a red solution to be titrated;

[0024] (2) Titrate the solution to be titrated with 0.1mol / L hydrochloric acid standard solution until the red color of the solution to be titrated becomes colorless as the titration end point, and write down the milliliters of the consumed hydrochloric acid standard solution, which is the cleaning ...

Embodiment 2

[0026] Another quick degreasing and descaling cleaning agent of the present invention, its component and weight percent thereof are:

[0027]

[0028] Dilute the cleaning agent to 8% by weight to obtain a cleaning solution. Under the conditions of a temperature of 45° C. and a free alkali content of 20 points, the workpiece is cleaned with the cleaning solution for 7 minutes.

[0029] The embodiment of the mensuration of described free alkali content is identical with embodiment 1.

Embodiment 3

[0031] Another quick degreasing and descaling cleaning agent of the present invention, its component and weight percent thereof are:

[0032]

[0033] Dilute the cleaning agent to 10% by weight to obtain a cleaning solution. Under the conditions of a temperature of 40° C. and a free alkali content of 30 points, the workpiece is cleaned with the cleaning solution for 6 minutes.

[0034] The embodiment of the mensuration of described free alkali content is identical with embodiment 1.

[0035] Use the cleaning agents of the three embodiments of the present invention to clean the workpieces respectively. The workpieces are workpieces with a large amount of oil stains (mainly hydraulic oil) and a large amount of dirt with unknown components. The cleaned workpieces and the workpieces cleaned with ordinary cleaning agents For comparison, the results are as follows:

Abstract

The invention discloses a cleaning agent for fast deoiling and descaling and a method for cleaning a workpiece by using the same. The cleaning agent comprises sodium metasilicate, sodium hydroxide, sodium carbonate, sodium citrate, oxidizing agents, surface active agents RQ-139 and water, wherein the sodium metasilicate, the sodium hydroxide and the sodium carbonate play emulsifying deoiling roles; the sodium citrate is a complexing agent, has dispersion and suspension functions, can be used for softening hard scale and preventing precipitates from being generated and plays a scale inhibition and dissolution roles; the oxidizing agent plays a fast deoiling and descaling role. The cleaning agent disclosed by the invention is colorless or milk-white without odor, can be used for fast removing the oil stains and scale which are positioned on the surface of the workpiece and has very high cleaning capacity on the surface of the workpiece with multiple oil varieties and much scale and good cleaning effect on hydraulic oil especially.

Description

technical field [0001] The invention relates to a cleaning agent for cleaning parts of automobiles, engineering machinery and agricultural machinery, in particular to a cleaning agent for quick oil and dust removal and a method for cleaning workpieces using the cleaning agent. Background technique [0002] In the process of mechanical processing, mechanical manufacturing, etc., the workpiece is often contaminated with various oil stains and dirt. Some workpieces are hard to remove because they have not been cleaned for a long time. Strong decontamination cleaning is necessary. agent to clean. Although traditional cleaning agents have a certain ability to clean dirt, they have little effect on the hard dirt that has been agglomerated. Some cleaning agents need to be treated for a long time to soften the hard dirt, thus prolonging the cleaning time. In addition, traditional cleaning agents are difficult to achieve the ideal cleaning effect on the workpiece surface with variou...
