Problems solved by technology

After actual comparison and use, it is found that the development ideas of the existing technical products of the above-mentioned companies are mostly limited to the research of carbon deposit cleaning technology from oil removal, while ignoring the particularity of carbon deposits, resulting in the fact that cleaning agents generally have good oil removal effects, but carbon deposit removal The effect is not good enough, showing that the carbon deposition cleaning technology is still difficult to meet the cleaning needs of aviation equipment

Embodiment 1

[0018] Add two-thirds of the water of the total weight of the composition into the container tank, and preheat the aqueous solution to 45 ° C ~ 55 ° C; , activating agent, and activating agent are poured into a container tank with an aqueous solution, directly mixed together and stirred for more than 15 minutes, fully dissolved, and made into the first group A water-based cleaning agent composition solution.

[0019] Add two-thirds of the water of the total weight of the composition in another container tank, then add corrosion inhibitors, stabilizers and sodium hydroxide according to any specific value in the above weight percentage, and stir for more than 15 minutes, Allow to fully dissolve to form a second Part B water-based cleaner composition solution.

Embodiment 2

[0021] Under normal temperature and pressure, according to the components specified in Table 1, according to the method described in Example 1, the compound CK-1 and CK-2 active agent; the selected sodium silicate synergist is added to ethanolamine The above-mentioned corrosion inhibitor and stabilizer are added to the activator; and methyl cellulose is selected as the thickener, and added into the additive methyl cellulose or ethanol and alcohol ether to prepare a cleaning agent. When in use, the pH value of the cleaning solution diluted to 20% should be between 7.0 and 11.5. The above-mentioned CK-1 and CK-2 are surfactants with good effect compounded by AES, AESA, SDS, LAS, TX-10, and phosphoric acid diesters. Among them, CK-1 is a compound of AESA, LAS, and TX~10 at a ratio of 2:3:5, and CK-2 is a compound of TX~10 and phosphodiester at a ratio of 1:1.

Embodiment 3

[0023] Repeat the method of Experimental Example 1 according to the content of each combination specified in Table 1 below to obtain water-based cleaning agent compositions with different components. The test results are shown in Table 1.

[0024] Table 1 Specific parameters of the example experiment

[0025] components

[0026] Note: in Table 1, the content of various components is the weight % based on the total weight of the composition, and the balance is tap water. When cleaning and using, then dilute to 20% aqueous solution. As can be seen from the test results shown in table 1, the cleaning agent composition provided by the invention can remove 45# steel parts surface and carbon deposit heavy oil dirt in a short period of time, and to 45# steel substrate surface corrosion amount All qualified.

Abstract

This invention claims a water-base cleaning agent composition capable of quickly removing carbon deposit and heavy oil, which can greatly improving performances of removing each heavy oil stain, cleaning dirt, resisting hard water and corrosion inhibition, especially the strongest performance of removing the carbon deposit at the metallic surface, solving the problems the current technology cannot remove each carbon deposit attached to the metal surface and the impurity cannot dissolve. This invention is realized by using following technical scheme: mixing 1% to 5% of synergistic agent, 0% to 10% of sodium hydroxide, 15% to 18% of activating agent, 0 to 5% of energizer, 4% to 8% of inhibiter, 0.5 to 1.5% of stabilizing agent, 0 to 5% of additive with water to prepare the water-base cleaning agent composition. This invention is suitable for cleaning components in the processing processes of each metal, alloy and non-metal in the machine manufacture and maintenance process, and cleaning the carbon deposit and the heavy oil stain. This invention is a non-ODS environmentally friendly water-base cleaning agent.

Description

technical field [0001] The invention relates to a cleaning agent suitable for cleaning parts and products thereof between various metals and alloys and non-metal processing procedures in the process of mechanical manufacturing and maintenance. More specifically, the invention relates to a cleaning agent for removing carbon deposits and Composition of water-based cleaners for heavy oil stains. Background technique [0002] The cleaning of carbon deposits has always been a technical difficulty in the field of aviation maintenance at home and abroad, and it is also recognized by the cleaning industry as the most stubborn dirt removal. It is difficult to carry out non-destructive testing and precision measurement on aero-engine parts without cleaning to remove carbon deposits, let alone repair and repair of parts. It is the first process of parts remanufacturing. To this end, countries all over the world have studied many technological methods, such as: sandblasting, rolling, v...
