Problems solved by technology

As the first process of remanufacturing, dismantling directly affects the processing efficiency of remanufacturing and the reuse rate of old parts, because during the use of equipment, due to corrosion, deformation, dust and other reasons, it is difficult to dismantle equipment parts, and the dismantling process It is easy to cause parts to be scrapped and lose opportunities for remanufacturing. For this reason, domestic and foreign remanufacturing fields are researching and developing equipment, technologies and materials for efficient dismantling of equipment parts. Among them, environmentally friendly and efficient cleaning agents are equipment remanufacturing important material in the field
The cleaning agents currently on the market generally only have a single effect in degreasing, rust removal, rust prevention, and penetration, or a combination of the two effects. They often show some defects in use, and it is difficult to achieve fast, efficient, and comprehensive effects. Therefore, the development of A cleaning agent with rust removal, rust prevention, cleaning and strong penetration, which is of great significance to the efficiency and value of equipment remanufacturing

Embodiment 1

[0017] Example 1 Preparation of an environmentally friendly cleaning agent for non-destructive disassembly of equipment parts

[0018] The formula is: oxalic acid, 4%; dodecyltrimethylammonium bromide, 1.5%; hexamethylenetetramine, 0.08g / L; hydroxymethylcellulose, 0.15%; the balance is water.

[0019] The preparation method is as follows: take all the raw materials except water, dissolve them separately, and mix them evenly to obtain the product.

[0020] The method of use is: apply the cleaning agent to the connecting parts of the parts for 1 to 2 hours.

[0021] This example uses the effective compounding of environmentally friendly raw materials to obtain an environmentally friendly and efficient cleaning agent with weak acidity, complexation, high permeability and surface transformation. After use, it can quickly penetrate into the contact parts of parts and remove the contact surface. At the same time, an insoluble oxalate film is formed on the fresh interface, which pla...

Embodiment 2

[0023] Example 2 Preparation of an environmentally friendly cleaning agent for non-destructive disassembly of equipment parts

[0024] The formula is: oxalic acid, 2%; OP-10, 2%; hexamethylenetetramine, 0.05g / L; hydroxymethylcellulose, 0.2%; the balance is water.

[0025] The preparation method is the same as in Example 1.

Embodiment 3

[0026] Example 3 Preparation of an environmentally friendly cleaning agent for non-destructive disassembly of equipment parts

[0027] The formula is: oxalic acid, 5%; polyethylene glycol, 1%; allylthiourea, 0.1g / L; hydroxymethylcellulose, 0.1%; the balance is water.

[0028] The preparation method is the same as in Example 1.

Abstract

The invention discloses an environmental-protective cleaning agent used for lossless disassembly of equipment parts. The environmental-protective cleaning agent consists of following raw materials: 2-5% by weight of oxalic acid, 1-2% of OP-10 or / and dodecyl trimethyl amine bromide and polyethylene glycol, 0.05-0.1 g / L of hexamethylenetetramine or allylthiourea, 0.1-0.2% of hydroxymethyl cellulose and the balance water. The environmental-protective cleaning agent used for lossless disassembly of the equipment parts has a faintly acid property, a complexing property, a high permeability and a surface transformation effect, has a comprehensive effects including loosening, oil removing, rust removing and rust resistance, can increase disassembly efficiency and a reproducing utilization ratio of the parts. A particular use method of the environmental-protective cleaning agent includes a following step of coating joints of the parts by the cleaning agent for 1-2 hours.

Description

technical field [0001] The invention relates to an environment-friendly cleaning agent used in the non-destructive disassembly of components in the equipment remanufacturing process, belonging to the technical field of cleaning and rust prevention. Background technique [0002] Remanufacturing is an emerging industry at home and abroad. Its basic connotation is the processing process of repairing and technologically transforming parts or products that have reached their service life to make them meet or even exceed the performance of prototype products. It is a concrete embodiment of the principle of reuse in circular economy. [0003] The remanufacturing process mainly includes five parts, namely, efficient non-destructive dismantling and sorting recycling technology of waste parts, environmentally friendly and efficient green cleaning technology, remaining life evaluation technology of waste parts, automated surface engineering remanufacturing technology and remanufacturi...
