Aqueous rust preventive for detection equipment and preparation method of aqueous rust preventive

Abstract

The invention provides an aqueous rust preventive for detection equipment and a preparation method of the aqueous rust preventive. The aqueous rust preventive comprises the following components: sodium nitrite, anhydrous sodium carbonate, polyethylene glycol, glycerol, triethanolamine, lecithin, alkylphenol polyethenoxy ether, carboxymethyl cellulose, citric acid, 2-phenoxy ethanol, ethanol and deionized water. The preparation method comprises the following steps: adding sodium nitrite, polyethylene glycol, glycerol, lecithin, carboxymethyl cellulose and citric acid into the deionized water, heating, stirring, and then cooling to room temperature to obtain a first mixed solution; mixing anhydrous sodium carbonate, triethanolamine, alkylphenol polyethenoxy ether, 2-phenoxy ethanol and ethanol, heating and stirring under a vacuum condition, and then quickly cooling to 0-5 DEG C to obtain a second mixed solution; and finally, uniformly mixing the first mixed solution and the second mixed solution by stirring to obtain the aqueous rust preventive for the detection equipment. The aqueous rust preventive provided by the invention has good antirust performance, is convenient to use, is stable in performance, cannot cause adverse effects on the equipment, and is suitable for widespread use.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to antirust water for testing equipment and a preparation method thereof. Background technique [0002] There are many types of testing equipment currently used. For example, there are many testing equipment commonly used in factories, including measuring equipment calipers, balances, etc. In addition, quality testing and analysis equipment, material testing, packaging testing equipment, etc. are also common testing equipment. In the packaging process, there are packaging material detectors, metal detection equipment, non-metal detection equipment and non-destructive testing equipment. In order to ensure the safety and sanitation of food, medicine and other products, production enterprises need to carry out corresponding testing on pre-production, production, packaging links and packaged products, so testing equipment must be used. Some sophisticated testing equ...

Problems solved by technology

Some sophisticated testing equipment not only needs to be debugged and calibrated regularly, but also needs to be maintained. In the long-term use process, the corrosion of such equipment will bring different degrees of damage to the equipment, resulting in shortened service life of the testing equipment. The accuracy drops. If cleaning and maintenance are not carried out in time, it will bring great errors to the accuracy of the tested products, which will affect the benefits of the enterprise.

[0003] At present, there are not many reagents specially used to detect the rust prevention of equipment. Most of them are common derusting solutions. These reagents are usually used directly on the surface of equipment for derusting. There are often residues that are not cleaned well in the dead corners, which often have adverse effects on the equipment during long-term use. Therefore, it is necessary to develop a rust removal solution that can not be directly used on the surface of the equipment. It can be used without contacting the equipment.
