Washing agent used for metal parts

Abstract

The invention discloses a washing agent used for metal parts, which is prepared from following raw materials, by weight: 10-12 parts of 3,3-dimethylpentane, 9-13 parts of a surface inhibitor, 5-10 parts of sodium hydroxide, 5-10 parts of sodium bichromate, 7-9 parts of deionized water, 2-3 parts of glycol stearic acid diester, 1.5-3 parts of oleamide and 1-2 parts of a hydrophobic modification alkali-swelling thickening agent. The washing agent is scientific and reasonable in formula, is simple in preparation technology and is free of requirement of special devices. The washing agent can be prepared just by mixing the raw materials above at the room temperature. The washing agent is strong in washing performance, is short in washing time, can save labor intensity and working time, can increase work efficiency and has functions of removing and preventing rust. The washing agent is alkaline and is low in corrosion on equipment, is safe and reliable to use and can reduce the equipment cost. The washing agent is a water-soluble liquid so that waste liquid after washing is convenient to treat and discharge in conformity with an environmental protection.

Description

technical field [0001] The invention relates to a cleaning agent for metal parts, which belongs to the field of chemical products. Background technique [0002] Metal materials need to be cleaned before processing, and the amount of ordinary mechanical parts prepared by metal materials and precision components used in other fields is quite large, so the workload of cleaning such metal parts is correspondingly large. The amount of cleaning agent required in the cleaning process must also be quite large. With the stringent environmental protection requirements and standards, the discharge control of industrial wastewater is becoming more and more stringent. Therefore, the discharge of a large number of waste cleaning agents has become an important topic for this industry to study. In addition, most of the existing cleaning agents for metal copper materials are solvent-based, phosphorus-containing water-based cleaning agents, etc. The disadvantages of these cleaning agents are...

Problems solved by technology

In addition, the existing cleaning agents for metal copper materials are mostly solvent-based, phosphorus-containing water-based cleaning agents, etc. The disadvantages of these cleaning agents are that the cleaning effect is not very ideal, and the metal parts after cleaning are prone to black surface layers, which is harmful to the follow-up. Processing brings trouble, especially for the processing of precision components; it is highly corrosive to equipment and increases the cost of equipment; cleaning time is longer
