1. Introduction

Metal surface treatment is an indispensable part of industrial production, and its purpose is to improve the corrosion resistance, wear resistance and aesthetics of metal materials. As an important additive in metal surface treatment, corrosion inhibitors can effectively delay the corrosion process of metals and extend the service life of metal materials. As a highly efficient corrosion inhibitor, DMEA (dimethylamine) has been widely used in the field of metal surface treatment in recent years. This article will introduce in detail the basic properties, application advantages, usage methods and market prospects of DMEA.

2.3 Chemical Properties

DMEA is a weakly basic compound that can react with acid to form salts. The hydroxyl groups and amino groups in their molecules make them have good water solubility and reactive activity, and can form a protective film on the metal surface, thereby acting as a corrosion inhibitor.

3. Application of DMEA in metal surface treatment

3.1 Metal Cleaning

DMEA is commonly used in metal cleaning agents and can effectively remove oil stains, rust and other impurities on the metal surface. Its alkaline properties allow it to neutralize acidic substances and prevent further corrosion of the metal surface.

3.2 Metal passivation

DMEA can react chemically with the metal surface during metal passivation to form a dense oxide film, thereby improving the corrosion resistance of the metal.

3.3 Electroplating

DMEA can be used as an additive in the electroplating solution to improve the uniformity and adhesion of the plating layer, reduce pores and defects in the plating layer, and improve the corrosion resistance and wear resistance of the plating layer.

3.4 Paint

DMEA is commonly used in the formulation of metal coatings, which can improve the adhesion and corrosion resistance of the coating and extend the service life of the coating.

4. Advantages of DMEA as a corrosion inhibitor

4.1 Efficiency

DMEA can form a dense protective film on the metal surface, effectively preventing the invasion of corrosive media, thereby significantly extending the service life of the metal material.

4.2 Environmental protection

DMEA is a low-toxic and low-volatility compound, environmentally friendly and meets the environmental protection requirements of modern industry.

4.3 Multifunctionality

DMEA not only has corrosion inhibitory effect, but also has various functions such as cleaning, passivation, electroplating and coating, which can meet the needs of different metal surface treatments.

4.4 Economy

DMEA has a low production cost and a small amount of use, which can effectively reduce the cost of metal surface treatment and improve economic benefits.

4.5 Stability

DMEA can maintain stable corrosion inhibition performance in harsh environments such as high temperature and high humidity, and is suitable for various complex industrial environments.

5. Comparison of DMEA with other corrosion inhibitors

Corrosion Inhibitor	Corrosion Inhibiting Effect	Environmental	Verifiability	Economic	Stability
DMEA	Efficient	High	High	High	High
Benzotriazole	Medium Effect	in	in	in	in
Phosphate	Inefficient	Low	Low	Low	Low
Silicate	Medium Effect	in	in	in	in

From the above table, it can be seen that DMEA is superior to other common corrosion inhibitors in terms of corrosion inhibition effect, environmental protection, versatility, economy and stability.
