Embodiment 1

[0027] A kind of metal derusting agent is made up of the raw material of following weight part:

[0028] 21 parts of hydrochloric acid,

[0029] 16 parts tartaric acid,

[0030] 5 copies of HS-99,

[0031] Lauryl sulfuric acid 5 parts,

[0032] 11 parts of ethylenediaminetetraacetic acid.

Embodiment 2

[0034] A kind of metal derusting agent is made up of the raw material of following weight part:

[0035] 23 parts of hydrochloric acid,

[0036] 18 parts tartaric acid,

[0037] 8 copies of HS-99,

[0038] 8 parts lauryl sulfate,

[0039] 16 parts of ethylenediaminetetraacetic acid.

[0040] Based on the above, the present invention is prepared by mixing hydrochloric acid, tartaric acid, HS-99, lauryl sulfuric acid and additives according to the weight ratio, and the prepared metal rust remover has strong degreasing and derusting ability, and fast derusting , the advantages of less pickling time and high cleaning rate.

Abstract

The invention discloses a metal rust removing agent and relates to the technical field of machinery. The metal rust removing agent is characterized in that the metal rust removing agent is composed ofthe following raw materials of, by weight, 20-25 parts of hydrochloric acid, 15-20 parts of tartaric acid, 5-10 parts of HS-99, 5-10 parts of dodecyl sulfuric acid and 10-20 parts of an annexing agent. The metal rust removing agent is prepared by mixing the above raw materials according to the weight proportion, and the prepared metal rust removing agent has the advantages of being high in oil dirt and rust removing ability, fast in rust removing, less in acid pickling time and high in cleaning rate.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a metal rust remover. Background technique [0002] Both hot-rolled steel and pipes before cold processing need to be pickled to remove scale. The traditional method is high-temperature pickling, which consumes a lot of energy, is highly corrosive to the steel substrate, has a lot of acid mist, and the speed of rust and scale removal is slow. . Water-based metal cleaning agent is a product with cleaning ability formulated with surfactant as the main component plus additives and other additives. It also has the characteristics of energy saving, non-toxic, less pollution, and low cleaning cost. It cannot meet the current cleaning industry's requirements for metal cleaning agents. Contents of the invention [0003] The problem to be solved by the present invention is to provide a metal derusting agent with strong degreasing and derusting ability, fast derusting, less pickling ...
