From the performance results of the fourth to tenth examples, it can be seen that the compound cleaning effect of the alkyl glycoside and AEO-9 is more excellent. The alkyl polyglycoside and lauryl glucoside are not beneficial to permeation due to larger molecular weight than alkyl glucoside, so that the degumming capability of the alkyl polyglycoside and lauryl glucoside is slightly weaker. The alkyl polyglycoside is compounded with the anionic surfactant, so that the solution viscosity is increased, and the removal of glue is not facilitated, so that the performance is relatively poor.

Comparative example 1

The difference from the first embodiment is that the first surfactant triethanolamine is not added, and the rest is the same as the first embodiment, and the description is omitted here. After the workpiece is cleaned and dried by adopting the steps S101-S110, the residual glue of the threaded hole of the workpiece is 3.46%, the residual glue of the outer surface of the workpiece is 80.75%, and the gas defense grade is A grade.

Comparative example No. two

Different from the first embodiment, the second surfactant alkyl glycoside and AEO-9 are not added, and the rest is the same as the first embodiment, and the description is omitted. After the workpiece is cleaned and dried by adopting the steps S101-S110, the residual glue of the threaded hole of the workpiece is 1.64%, the residual glue of the outer surface of the workpiece is 70.94%, and the gas protection grade is A grade.

In the first to seventeenth embodiments, the residual glue for cleaning the threaded hole of the workpiece by the cleaning agent is 0.15-1.67%, and the residual glue on the outer surface of the workpiece is 33.37-50.43%. In contrast, the residual glue of the threaded hole of the workpiece is 3.46% -1.64% respectively, and the residual glue of the outer surface of the workpiece is 80.75% -70.94% respectively. In comparative example one, the large molecules of the polyester-based binder could not be decomposed and dispersed due to the absence of the first surfactant, and the polyester-based binder adhered to the workpiece was hardly dispersed by the molecules of the second surfactant, resulting in a large amount of residual gum. In the comparative example II, due to the lack of the wrapping effect of the second surfactant, the glue is deposited on the screw hole and the outer surface of the workpiece, and more glue residues are generated. The cleaning agent and the cleaning method can accurately clean the threaded holes of the workpieces after vacuum impregnation and residual glue on the outer surfaces of the workpieces, and are high in cleaning efficiency.
