Preventing IBC Pallet Corrosion: Built-In Acid Protection in Modern Tank Manufacturing

In the chemical and liquid storage industries, IntermediateBulk Containers (IBCs) are indispensable tools. These robust containers safely and efficiently transport and store a wide range of substances, from harmless liquids to highly corrosive chemicals. The IBC pallet, as a crucial component, plays a vital role in supporting and stabilizing the container. However, when dealing with acidic substances, pallet corrosion becomes a significant concern. Corrosion can compromise the structural integrity of the pallet, leading to potential leaks, environmental contamination, and costly damage. Fortunately, modern tank manufacturing has introduced innovative solutions with built-in acid protection to address this issue.

• Corrosion Principles and Influencing Factors

Corrosion is a natural process where materials deteriorate due to chemical reactions with their environment. In the case of IBC pallets exposed to acids, understanding the corrosion principles is essential. There are two primary types of corrosion: electrochemical and chemical. Electrochemical corrosion involves the formation of anodic and cathodic regions on the metal surface, leading to electron transfer and metal dissolution. Chemical corrosion occurs when the acid directly reacts with the metal, resulting in the formation of metal salts and hydrogen gas.

Several factors influence the rate and severity of corrosion. The type and concentration of the acid play a crucial role. Strong acids like sulfuric and hydrochloric acid are highly corrosive, while weaker acids may cause less damage. Temperature also affects corrosion, as higher temperatures generally accelerate the reaction rate. Additionally, environmental factors such as humidity and the presence of chloride ions can exacerbate corrosion.
