Problems solved by technology

[0003] Metal workpieces are prone to rust when placed outdoors or in the open air, which not only affects the quality of the workpiece, but also affects the normal progress of painting, bonding and other processes. If it is not handled in time, the materials will be scrapped and unnecessary economic losses will be caused.
At present, the rust remover used often destroys the material of the workpiece itself and causes corrosion while derusting the workpiece, and also produces a large amount of waste gas and waste liquid while derusting, seriously affecting the environment

Embodiment Construction

[0016] A kind of novel derusting agent, used raw material and weight percent are as follows:

[0017] Acetic acid 10-25%

[0018] Citric acid 6~15%

[0019] Hexamethylenetetramine 5 ~ 18%

[0020] Sodium phosphate 11~19%

[0021] Corrosion inhibitor 0.5 ~ 2.6 %

[0022] Herotropine 5 ~ 10%

[0023] Triethanolamine 5 ~ 12%

[0024] water balance.

[0025] The production method of the novel rust remover is carried out according to the following steps: under normal temperature and pressure conditions, add water, acetic acid, sodium phosphate and hexamethylenetetramine into the container, stir and dissolve all of them, then add citric acid, urethane After the rotropine and triethanolamine are completely dissolved by stirring, the corrosion inhibitor is added and stirred, sampling and testing are carried out, and the packaging process is entered.

[0026] The test item indicators are as follows:

Abstract

The invention discloses a novel rust remover. The novel rust remover comprises 10-25wt% of acetic acid, 6-15wt% of citric acid, 5-18wt% of hexamethylene tetramine, 11-19wt% of sodium phosphate, 0.5-2.6wt% of a corrosion inhibitor, 5-10wt% of urotropine, 5-12wt% of triethanolamine, and the balance of water. A production method of the novel rust remover comprises the following steps: adding water, acetic acid, sodium phosphate and hexamethylene tetramine into a container at normal temperature under normal pressure, stirring until complete mutual dissolution, adding citric acid phosphonic acid, urotropine and triethanolamine, stirring, adding the corrosion inhibitor after complete dissolution, sampling, detecting, and packaging.

Description

technical field [0001] The invention relates to the field of fine chemical industry, in particular to a new type of rust remover which is low in cost and does not cause corrosion to the material of workpieces at the same time of rapid rust removal [0002] and production methods. Background technique [0003] Metal workpieces are prone to rust when placed outdoors or in the open air, which not only affects the quality of the workpiece, but also affects the normal progress of painting, bonding and other processes. If it is not handled in time, the materials will be scrapped and unnecessary economic losses will be caused. . At present, the rust remover used often destroys the material of the workpiece itself to cause corrosion while derusting the workpiece, and also produces a large amount of waste gas and waste liquid while derusting, which seriously affects the environment. Contents of the invention [0004] The purpose of the present invention is to solve the above-ment...
