Abstract
The invention discloses a steel normal-temperature derusting liquid, which contains the following main components of: by weight, 0.5-0.6% of oxalic acid, 0.4-0.5% of sodium dodecyl sulfate, 2.2-2.5% of phosphoric acid, 50-55% of hydrochloric acid, 0.6-0.8% of fatty alcohol polyoxyethylene ether, 0.4-0.6% of hexamethylenetetramine and 40-45% of water. The derusting liquid prepared in the invention can be used to rapidly remove rust and metal scale on steel, and simultaneously has functions of alleviating steel corrosion, inhibiting acid fog spraying and the like.
Description
Technical field
The present invention relates to a kind of rust cleaning liquid, be specifically related to a kind of iron and steel normal temperature rust cleaning liquid.
Background technology
Usually use the sulfuric acid of heating, the hydrochloric acid or the mixing acid of normal temperature to clean to the treatment process of impurity such as the corrosion of steel surface, oxide debris, but there are a lot of shortcomings in this method, like big energy-consuming, can produce hydrogen embrittlement to the body metal, make steel weightless, produces acid mist etc.
Summary of the invention
Goal of the invention: the present invention provides a kind of iron and steel normal temperature rust cleaning liquid of quick derusting at normal temperatures in order to solve the deficiency of prior art.
The technical scheme that the present invention adopts: a kind of iron and steel normal temperature rust cleaning liquid, staple comprises oxalic acid, sodium lauryl sulphate, phosphoric acid, hydrochloric acid, AEO, vulkacit H, water, the weight percent of said each component of rust cleaning liquid is:
Oxalic acid 0.5-0.6%
Sodium lauryl sulphate 0.4-0.5%
Phosphoric acid 2.2-2.5%
Hydrochloric acid 50-55%
AEO 0.6-0.8%
Vulkacit H 0.4-0.6%
Water 40-45%
As preferably, described phosphoric acid is the solution of concentration 85%.
As preferably, described hydrochloric acid is the solution of concentration 33%.
In the present invention, oxalic acid is as deoiling rust remover, and sodium lauryl sulphate, AEO are as emulsifying agent, and phosphoric acid, hydrochloric acid are as rust remover, and vulkacit H is as acid fog inhibitor.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: iron and steel normal temperature provided by the invention rust cleaning fluid power is removed rusty stain and burning skin on the iron and steel at normal temperatures fast, also has the steel corrosion of slowing down simultaneously, suppresses effect such as acid mist eruption.
