The powerful oil stain removing agent prepared in the embodiments 1-10 and the comparative examples 1-2 is applied to the treatment of oil stains on the metal surface, wherein the product is powdery, metal parts can be placed in an ultrasonic cleaning device when the metal surface is treated, and then the product is put into the ultrasonic cleaning device; the product can also be dissolved firstly, and then the solution is utilized to treat the oil stain on the metal surface. The test results are shown in Table 1. The results of the detergency tests in the following table are the results of the experiments of dissolving the product and then treating the greasy dirt on the metal surface, and the corrosion resistance tests are the results of the products after treating the metal and then placing the treated metal for 3 weeks.
TABLE 1
| Detergency (%) | Resistance to corrosion | Detergency (%) | Resistance to corrosion | ||
| Example 1 | 99.1 | No rusting | Example 7 | 98.2 | No rusting |
| Example 2 | 99.0 | No rusting | Practice ofExample 8 | 97.7 | No rusting |
| Example 3 | 97.3 | No rusting | Example 9 | 99.3 | No rusting |
| Example 4 | 98.3 | No rusting | Example 10 | 99.4 | No rusting |

| Example 6 | 98.5 | No rusting | Comparative example 2 | 89.6 | No rusting |
According to the test results, the product has good oil stain removal capability on the metal surface, if the proportion of each substance is controlled to reach over 99 percent of oil stain removal capability, and the oil stain removal capability is expected to reach 100 percent by matching with an ultrasonic cleaning device for treatment, the oil stain removal capability is fast, the solution containing the product is only needed to wipe the metal surface, and if the small metal part is directly placed into the ultrasonic cleaning device, the oil stain can be removed more quickly, and the effect is good.
It can be seen from the comparison between examples 1 and 9 and examples 2 and 10 that the degreasing agent added with polyethylene glycol has a more excellent degreasing effect, probably because of the dispersibility of polyethylene glycol, when the powdery degreasing agent is dissolved in water, the powdery degreasing agent can be dispersed uniformly, so that the composite silicate mineral powder and citric acid can be in better contact with the metal surface, and further, the more excellent degreasing effect can be achieved. In addition, because the composite silicate mineral powder is lack of neutralization of citric acid acidity, after metal is cleaned, the citric acid has a certain corrosion effect on the metal, so that the oil stain removing agent cannot well have the anti-rusting effect; the degreasing agent without citric acid is also not harmful to the product in terms of degreasing capability. Therefore, the composite silicate mineral powder and the citric acid are compounded for use, so that the strong oil stain removal effect can be achieved, a certain anti-rusting effect can be achieved, and the composite silicate mineral powder and the citric acid are suitable for the requirements of removing the oil stains on the metal surface at present.
Variations and modifications to the above-described embodiments may also occur to those skilled in the art, which fall within the scope of the invention as disclosed and taught herein. Therefore, the present invention is not limited to the above-mentioned embodiments, and any obvious improvement, replacement or modification made by those skilled in the art based on the present invention is within the protection scope of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
