Embodiment 1

[0021] In the present embodiment, 70% of octylphenol polyoxyethylene (10) ether, 10% of hexamethylenetetramine, 10% of n-butanol, and 10% of sodium benzoate are taken by weight percentage, and these raw materials are uniformly mixed to obtain The anti-scale explosion pickling additive for cold-rolled enamelled steel of the present invention. Adding 1.0% of this additive in hydrochloric acid pickling with a mass fraction of 18% and pickling at 60°C can significantly improve the pickling quality of the steel plate surface and improve the anti-scaling performance of the steel plate.

Embodiment 2

[0023] In the present embodiment, 50% of octylphenol polyoxyethylene (10) ether, 25% of hexamethylenetetramine, 20% of n-butanol, and 5% of sodium benzoate are taken by weight percentage, and these raw materials are uniformly mixed to obtain The anti-scale explosion pickling additive for cold-rolled enamelled steel of the present invention. Adding 1.5% of this additive in hydrochloric acid pickling with a mass fraction of 16%, and pickling at 80°C, can obviously improve the pickling quality of the steel plate surface and improve the anti-scaling performance of the steel plate.

Embodiment 3

[0025] In the present embodiment, 55% of octylphenol polyoxyethylene (10) ether, 10% of hexamethylenetetramine, 15% of n-butanol, and 20% of sodium benzoate are taken by weight percentage, and these raw materials are uniformly mixed to obtain The anti-scale explosion pickling additive for cold-rolled enamelled steel of the present invention. Adding 1.4% of this additive in hydrochloric acid pickling with a mass fraction of 14% and pickling at 75°C can significantly improve the pickling quality of the steel plate surface and improve the anti-scaling performance of the steel plate.

Abstract

The invention discloses a fish-scaling-resistance acid pickling additive used for cold-rolled glassed steel. The fish-scaling-resistance acid pickling additive is characterized in that the additive comprises, by weight, 50-70 percent of octylphenol polyoxyethylene (10) ether, 10-25 percent of hexamethylenetetramine, 10-20 percent of normal butanol and 5-20 percent of sodium benzoate. The additive has the advantages that an acid pickling solution can be stablized, the applicable hydrochloric acid concentration range and the acid pickling temperature range are wide, no strong pungent smell exists, and the operation environment is not affected.

Description

technical field [0001] The invention relates to an anti-scaling pickling additive for cold-rolled enamel steel, which belongs to the technical field of protection. Background technique [0002] Enamel products play a very important role in the national economy and are closely related to people in daily life. They are widely used in household appliances, metallurgy, light industry, chemical industry, construction and other industries, such as sanitary ware, barbecue ovens, kitchen utensils , water heater liner, building decorative panels, chemical reaction tanks, etc. [0003] During the production process of enamel products, hydrogen dissolves into the steel plate in the form of atoms. When the enamel product is cooled to room temperature, the dissolved hydrogen in the steel plate reaches supersaturation, diffuses to the interface between the steel plate and the enamel, and at the pores there, Atomic hydrogen recombines to form molecular hydrogen. These pores may be caviti...
