Embodiment

[0019] In this example, the following method is used to extract the fruit of Gardenia jasmine: Wash the fruit of Gardenia jasmine three times with deionized water, dry it at 353K for 24 hours, and then grind it into powder, heat and concentrate about 50 g of the powder in a container containing 2000 mL deionized water in a large beaker, and then filtered with a filter cloth to finally obtain a concentrated solution of about 15mL, freeze the concentrated solution in a refrigerator, and then dry it in a freeze-drying box for 24 hours to finally obtain a bright yellow substance, that is, yellow gardenia Fruit extract (Gardenia jasminoides fruits extract, GFE), the GFE is stored in a desiccator.

[0020] This embodiment has carried out electrochemical experiment, and the metal material used in experiment is red copper (99.9%), and except working surface, other positions are all cured and sealed with epoxy resin, made as electrode, working area is 1cm 2 . The instrument used for e...

Abstract

The invention relates to the technical field of corrosion inhibitor production, and discloses a gardenia jasminoides fruit extract corrosion inhibitor. The active component of the gardenia jasminoides fruit extract corrosion inhibitor is a water extract of gardenia jasminoides fruits, and applications are also disclosed. According to the gardenia jasminoides fruit extract corrosion inhibitor and the application thereof, the corrosion inhibitor can effectively slow down corrosion of copper in a sulfuric acid corrosion medium within a certain temperature range, raw materials of the corrosion inhibitor are convenient to obtain and rich, the corrosion inhibitor is simple in preparation process, free of pollution, low in cost, natural and harmless in contained components and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of corrosion inhibitor production, in particular to a corrosion inhibitor of gardenia jasmine fruit extract and application thereof. Background technique [0002] At present, the economic losses caused by metal corrosion to the country and the people cannot be ignored. According to the investigation, the losses caused by corrosion in various fields in our country account for about 3% of the gross national product. Therefore, it is urgent to control the corrosion of metals. As an important member of metals, copper has good electrical conductivity, thermal conductivity, high strength and machinability, and can be used for welding; while copper and its alloys have excellent corrosion resistance, anti-fouling properties and other characteristics. Therefore, for a long time, copper and its alloys have been widely used in various fields such as industry, military affairs, and civil use. However, in recent years, ...
