Abstract

This invention discloses an acidic detergent for carbon steel and its application. The acidic detergent is composed of xacin-series antibacterial drug and 0.1-2 M acid solution at a ratio of 0.010-5.0 kg / L. The acidic detergent can be applied by soaking carbon steel in the acidc detergent at room temperature for 15 min-3 h. The acidic detergent can prevent carbon steel from local or whole corrosion, and has such advantages as low usage amount, high corrosion-inhibiting efficiency, long effective time, no harm to the environment or creatures, etc., thus having good application potential.

Description

technical field

[0001] The invention relates to the technical field of corrosion inhibitor production, in particular to an acid cleaning agent for carbon steel and its application for preventing unnecessary overall corrosion and local corrosion of carbon steel and its products in the pickling process. Background technique

[0002] Carbon steel has good mechanical properties and process properties, and is cheap, so it is more and more widely used in various industries. In the process of product processing and application, dilute sulfuric acid or dilute hydrochloric acid is often used for pickling, which can remove the oxide film or corrosion products on the surface. In order to avoid excessive consumption of metal or acid during pickling and prevent harmful corrosion, acid Adding corrosion inhibitors is an effective means.

[0003] Currently commonly used pickling corrosion inhibitors mainly include inorganic corrosion inhibitors containing toxic chromate and some organic ph...
