Abstract

The invention discloses a surface treatment preparation for galvanized steel sheet and a surface pretreatment process, belonging to the technical field of steel sheet surface treatment. First, the surface of the untreated steel sheet is ground and processed, and then further treated with a surface treatment agent. The surface treatment preparation for galvanized steel sheet includes the following raw materials: phosphate ester compound, potassium hydrogen persulfate compound salt, hydrogen sulfate salt, quaternary ammonium aniline compound, sodium carbonate, ammonium acetate, hydroxyethylidene phosphoric acid, imidazoline and its derivatives compounds, acid pickling fog suppressants, alkynyl alcohol derivatives, alcohol ether carboxylates, stabilizers, chelating agents, water. The surface treatment preparation for galvanized steel plate provided by the technical solution of the present invention can effectively remove oil stains, oxide films, rust spots and other adhesive impurities on the surface of the steel plate. Volatile substances, wastewater treatment is simple, safe and environmentally friendly. After the steel sheet is treated as above, it helps to improve the quality and efficiency of the galvanized steel sheet.

Description

Technical field[0001]The present invention relates to a surface treatment technique of a steel sheet, specifically a surface treatment formulation and a surface treatment process for galvanizing steel sheets.Background technique[0002]Typically, the surface residual impurities are residual, or the surface is exposed for a long time, and the surface can form a variety of oxide films, rust, etc., which cannot be directly carried out, and surface treatment is required.[0003]Metal surface acid washing treatment is an indispensable process before galvanizing. It is mainly prepared by hydrochloric acid or sulfuric acid on the market. It has the advantages of rust fast, but it has strong corrosion, it is easy to cause corrosion. The subsequent treatment of the metal surface brings a lot of unnecessary trouble and hazards, such as bad problems such as rough steel sheets. At the same time, the treatment of pickling waste after treatment, due to strong corrosion, will cause irreversible hazard...
