Abstract
The invention discloses aluminium alloy hard anodizing electrolyte which is characterized by comprising the following components: 160 to 250g/L of sulfuric acid, 20 to 30g/L of oxalic acid and 8 to 10g/L of glycerin. After the technical scheme is adopted, the oxalic acid and the glycerin are added into sulfuric acid electrolyte, so that the temperature of the electrolyte can be risen to 0 to 4 DEG C, the ultralow temperature working is avoided and the energy is saved.
Description
Technical field
The present invention relates to a kind of duraluminum hard anodizing electrolytic solution, belong to the field of surface treatment of duraluminum.
Background technology
Hard anodizing commonly used is a sulfuric acid hard anodizing flow-through method, generally is to carry out at low temperatures, therefore, must be equipped with supporting refrigerating apparatus with do not have oil, preferably stir through refrigerative pressurized air, bring certain degree of difficulty to production.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of can be at the duraluminum hard anodizing electrolytic solution of oxidation under the comparatively high temps.
The present invention seeks to realize like this: a kind of duraluminum hard anodizing electrolytic solution, it is characterized in that: electrolyte component is: sulfuric acid 160-250g/L, oxalic acid 20-30g/L, glycerine 8-10g/L.
Adopt technique scheme, in sulfuric acid electrolyte, add oxalic acid and glycerine, can electrolysis temperature be brought up to 0-4 ℃, avoid very low temperature work, save energy.
As preferably: electrolyte component is: sulfuric acid 200-220g/L, oxalic acid 25-30g/L, glycerine 9-10g/L.
The present invention has following beneficial effect: high through electrolytic solution aluminium alloy treated rete slickness of the present invention, thicknesses of layers changes evenly, and thicknesses of layers can reach the 35-45 micron, more than the film hardness Gao Keda HV400.Tank liquor temperature can have been evaded the energy loss that the work of ordinary rigid anode oxidation process very low temperature brings near carrying out under the normal temperature.Only otherwise the inlet diet is not touched human body, in working link, human body is not had injury, the product of producing satisfies country and the relevant environmental requirement in Europe, and save energy is protected environment.
