a cleaning agent for molybdenum aluminum molybdenum coated glass, hereinafter referred to as "cleaning agent".
Referring to FIG. 1, FIG. 1 is an infrared spectrum of ethylenediamine tetraacetic acid at 3015.86cm -1 The methylene stretching vibration absorption peak is 1669.57cm -1 the-COOH vibration absorption peak was located.

Referring to FIGS. 1-2, the formation of ethylenediamine tetraacetic acid amide can be demonstrated from the difference in infrared spectra of ethylenediamine tetraacetic acid and the reaction product of ethylenediamine tetraacetic acid with monoethanolamine.
As can be seen from the combination of examples 1 to 4 and Table 1, the pH of the 1 to 20% aqueous solution of ethylenediamine tetraacetic acid amide was between 8.5 and 9.0, showing that the alkalinity was moderate and stable within a certain interval.
Referring to tables 2 and 3, ultrasonic cleaning, spray cleaning and soaking test results of the cleaning agents prepared by comparative examples 5 to 7; as the concentration of the ethylenediamine tetraacetic acid amide increases, the pH value of the cleaning agent gradually increases but is stabilized in the range of 8.0-9.0; along with the increase of the concentration of the organic solvent, the contact angles of the cleaned molybdenum aluminum molybdenum coated glass are gradually reduced and are smaller than 20 degrees, which shows that the infiltration wetting capability of the cleaning agent on the surface of the molybdenum aluminum molybdenum coated glass is improved along with the increase of the concentration of the organic solvent. The cleaning agent prepared under the three concentration gradients is used for ultrasonic cleaning and spray cleaning, foam generation is not seen, and after 2 hours of soaking treatment, the corrosion phenomenon of the surface of the molybdenum-aluminum-molybdenum coated glass is not seen. The cleaning agent prepared in the embodiments 5-7 of the application has moderate alkalinity and is not easy to corrode molybdenum aluminum molybdenum coated metal; the organic solvent is used for replacing the surfactant, so that the detergent has good infiltration detergency, is not easy to foam and is convenient for subsequent rinsing; the components do not contain metal ions, and new metal ions are not introduced in the cleaning process, so that hidden danger of metal ion residues is reduced, and the subsequent processing procedures are facilitated.
Referring to tables 2 and 3, examples 7 to 9 were carried out ultrasonic cleaning, spray cleaning and soaking tests on molybdenum-aluminum-molybdenum coated glass using cleaning agents prepared from different co-solvents, and the results show that three cleaning agents have no significant differences in cleaning and decontamination and corrosion effects, indicating that ethanol, propylene glycol and glycerol can be used as co-solvents for cleaning agents for molybdenum-aluminum-molybdenum coated glass.
Referring to tables 2 and 3, examples 7, 10, 11 and 12 were prepared using different organic solvents and were subjected to ultrasonic cleaning, spray cleaning and immersion test, and the results showed that the four cleaning agents were not significantly different in cleaning and corrosion effects; the dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, propylene glycol methyl ether and propylene glycol n-butyl ether can be used as organic solvents of cleaning agents for molybdenum aluminum molybdenum coated glass.
Referring to tables 2 and 3, examples 7, 13 and 14 used different cleaning agents with corrosion inhibitors, and the results of the soaking test on molybdenum-aluminum-molybdenum coated glass showed that three cleaning agents have no significant difference in corrosion prevention effect, indicating that BTA, MTA and TTA can be used as corrosion inhibitors for cleaning agents for molybdenum-aluminum-molybdenum coated glass.
Referring to tables 2 and 3, examples 7, 15, 16 and 17 were prepared using ethylenediamine tetraacetic acid amide obtained under different conditions as a pH stabilizer, and four cleaners were observed, and the corresponding transparency was gradually lowered, indicating that the higher the temperature or the longer the reaction time was, the overall transparency of the cleaner was affected; however, the four cleaning agents have no obvious difference in cleaning effect and corrosion effect on the molybdenum-aluminum-molybdenum coated glass.
Referring to tables 2 and 3, the cleaning agents prepared in comparative examples 7 and 1 had excellent dust cleaning ability and oil stain cleaning effect on the ultrasonic cleaning, soaking test and spray cleaning conditions of the molybdenum aluminum molybdenum glass coated glass.
The cleaning agent of comparative example 1 was added with monoethanolamine having strong basicity as an emulsifier, the pH of the dilute solution of the cleaning agent was 10.5, and the cleaning agent was a strongly basic cleaning agent. The cleaning agent of comparative example 1 is added with fatty alcohol polyoxyethylene ether (AEO-9), coconut oil alkanolamide (6501) and triethanolamine oleate as surfactants, so that the cleaning agent has higher penetration capacity, thereby improving the detergency, but more foam is generated in the ultrasonic cleaning process or the spray cleaning process, which is unfavorable for the subsequent rinsing and easily causes the cleaning agent to remain. EDTA-disodium is added as a metal chelating agent in the cleaning agent of comparative example 1, and new metal sodium ions are introduced during the cleaning process, which is easy to cause subsequent processing risks. After 2 hours of soaking test, a large number of netlike holes appear on the surface of the molybdenum-aluminum-molybdenum coated glass, which indicates that the cleaning agent prepared in comparative example 1 has a corrosion effect on molybdenum-aluminum-molybdenum coated metal due to high alkalinity.
The components of the cleaning agent in the embodiment 7 contain no metal ions or surfactants, but have high penetrating and wetting capacities and do not generate foam, so that the cleaning agent is convenient for subsequent rinsing; the pH value of the diluted solution is 8.91, the alkalinity is moderate, and the molybdenum-aluminum-molybdenum coated metal is not easy to corrode.
Referring to tables 2 and 3, the cleaning agents prepared in comparative example 7 and comparative example 2 were used for ultrasonic cleaning, soaking test and spray cleaning of the molybdenum-aluminum-molybdenum glass coated glass. The cleaning agent of comparative example 2 has poor cleaning ability on greasy dirt in ultrasonic cleaning or spray cleaning, because ethylenediamine tetraacetic acid amide is not added in the cleaning agent of comparative example 2, the pH value of the dilute solution of the cleaning agent is 7.51, and the cleaning agent is neutral; indicating that the detergency of the cleaning agent is reduced under low alkaline conditions.
Referring to tables 2 and 3, the cleaning agents prepared in comparative example 7 and comparative example 3 were used for ultrasonic cleaning, soaking test and spray cleaning of the molybdenum-aluminum-molybdenum glass coated glass. The cleaning agent of comparative example 3 has no obvious difference between the cleaning effect of the molybdenum aluminum molybdenum glass coated glass and the cleaning effect of the cleaning agent of example 7, but a small amount of meshes appear on the surface of the molybdenum aluminum molybdenum glass coated glass after soaking test, which indicates that the cleaning agent has a certain corrosion effect on the molybdenum aluminum molybdenum glass coated metal in the absence of the protection of the corrosion inhibitor.
Referring to tables 2 and 3, the cleaning agents prepared in comparative examples 7 and 4 were used for ultrasonic cleaning, soaking test and spray cleaning of the molybdenum-aluminum-molybdenum glass coated glass. The cleaning agent of comparative example 4 has a lower cleaning effect on the molybdenum aluminum molybdenum glass coated glass than the cleaning agent of example 7, which means that the cleaning agent lacking the cosolvent has poorer fusion property of each component, and the effect of each component cannot be exerted, so that the overall cleaning effect of the cleaning agent is affected.
Referring to tables 2 and 3, the cleaning agents prepared in comparative examples 7 and 5 were used for ultrasonic cleaning, soaking test and spray cleaning of the molybdenum-aluminum-molybdenum glass coated glass. After ultrasonic cleaning and spray cleaning are carried out by using the cleaning agent of comparative example 5, the contact angles of the molybdenum-aluminum-molybdenum coated glass are 31.3 degrees and 35.4 degrees respectively, which shows that the wettability of the cleaning agent of comparative example 5 is poor; oil marks remain after cleaning, which indicates that the organic solvent affects the wetting degree and degreasing capability of the cleaning agent on coated glass, and the incomplete cleaning of the oil stains also affects the cleaning of dust.
The application discloses a cleaning principle of cleaning agent for molybdenum aluminum molybdenum coated glass: the cosolvent promotes the solubility of the cleaning agent and improves the compatibility of all components, so that the cleaning agent is clear, stable and non-layered in appearance; the pH stabilizer ethylenediamine tetraacetic acid amide contains 4 amide groups, so that stable alkaline conditions are provided for the cleaning agent; the corrosion inhibitor forms a physical and chemical mixed adsorption film layer on the molybdenum-aluminum-molybdenum coated glass, so that the corrosion of coated metal by a cleaning agent is reduced; the organic solvent enables the cleaning agent to have higher penetrating and wetting capacity and realize the degreasing effect under the condition of no foaming; the amine atom of ethylenediamine tetraacetic acid amide can be used as a coordination atom for chelating metal ions in water so as to reduce the condition of residual scale after the molybdenum aluminum molybdenum coated glass is cleaned.
