Abstract

The invention discloses an organic rust conversion agent. The organic rust conversion agent comprises the following components in parts by weight: 5-10 parts of ethanol, 15-20 parts of tannic acid, 0.5-1.5 parts of acetylacetone, 35-65 parts of phosphoric acid, 1-3 parts of methyl gallate, 8-10 parts of sodium benzenesulfonate, and 10-18 parts of water. The rust conversion agent has the advantages of: easiness in taking of raw materials, low cost, capability of increasing the film forming rate and capability of prolonging the service life of equipment. A preparation method is simple; the adopted charging sequence and mixing step are not reported by documents so far; and the preparation method is an innovation, and can increase the film forming rate. An application method of the organic rust conversion agent is simple and convenient.

Description

technical field [0001] The invention relates to the field of chemicals, in particular to an organic rust converting agent and its preparation method and application method. Background technique [0002] In chemical production enterprises, some chemical equipment such as distillation towers, reactors, and conveying pipes are relatively common equipment, but these equipments have experienced chemical corrosion for a long time, which will reduce the service life of these equipments. Therefore, after the equipment has been used for a period of time, it needs to be derusted and maintained. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a low-pollution, easy-to-use rust conversion agent and its preparation method and use method. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] An organic rust con...
