Problems solved by technology

Ordinary water-based cleaning agents cannot meet the requirements in terms of cleaning speed or cleaning strength
[0004] 2. Aluminum and its alloys are extremely sensitive to impurities in air and water, and are prone to discoloration and loss of luster. It is impossible to paint or organically cover immediately after cleaning. If a separate passivation process is set up, the production cost will be greatly increased and the cost will be greatly increased. The process is more complicated
[0005] 3. Large-scale, continuous chemical industrial production requires that the cleaning working fluid has a large cleaning capacity and a long cleaning cycle, while ordinary cleaning agents cannot meet this requirement
So far there is no effective cleaning agent for aluminum and aluminum alloys

example 1

[0047] Prepare cleaning agent according to the following formula:

[0048] Nonylphenol polyoxyethylene ether 100Kg

[0049] Lauryl polyoxyethylene ether 90Kg

[0050] Tomadyne 100 50Kg

[0051] Propylene glycol butyl ether 50Kg

[0052] Glucose 50Kg

[0053] Sodium metasilicate 20Kg

[0054] Water 640Kg

[0055] Stir and mix the above raw materials at 25-35°C until they become transparent. The product is light yellow transparent liquid, density (g / cm 3 ) (specific gravity) is 1.05±0.02.

[0056] Ultrasonic cleaning is used when cleaning engine parts made of a type of aluminum alloy at 50-70°C for about 5 minutes. After cleaning, the surface of aluminum and its alloy parts shall be inspected with bright white light, and there shall be no loose particles with two-dimensional dimensions exceeding 0.05mm and three-dimensional dimensions exceeding 0.02mm, and no fluorescence when inspected with ultraviolet light (wavelength 0.32-0.38um); its surface Good hydrophobicity, no...

Abstract

The invention discloses an aluminium and aluminium alloy abluent, which comprises the following parts: 5-25W% alkyl phenol polyoxyethylene ether, 5-25W% aliphatic alcohol polyoxyethylene ether, 1-10W% cationic modified alkyl phenol polyoxyethylene ether, 2-10W% propanediol butyl ether, 2-8W% glucose, 1-8W% sodium bisilicate and 40-80W% water. The product displays light yellow transparent liquid with density at 1.05+-0.02 g / cm3, which simplifies normal disposal technique.

Description

Technical field: [0001] The invention belongs to the field of detergent compositions, and in particular relates to a surfactant-based composition, especially a mixture of propylene glycol ether, a mixture of nonionic compounds and cationic compounds. At the same time, it also involves the field of cleaning or degreasing metal materials with organic solvents containing carbon and hydrogen compounds. Background technique: [0002] The cleaning of aluminum and its alloys (especially the parts, components and precision instruments made of it) is much more complicated and difficult than that of other metals, because aluminum and its alloys have strong adsorption and active chemical properties. It is difficult to meet the cleaning rate requirements of precision cleaning. This is because: [0003] 1. The functional grease (rolling oil, calendering oil, lubricating oil, etc.) used in the production and processing of aluminum and its alloy parts is difficult to clean. The cleaning ...
