Steel-lined plastic corrosion-resistant storage tanks are also a type of corrosion-resistant storage tank. Under the corrosion and weathering effects of the external environment, the coating may peel off. Inadequate shrinkage of the corrosion-resistant coating is a major cause of cracking, which is why attention should be paid to the drying and curing process of the paint film on steel-lined plastic tanks. Today, let's explore the reasons behind this.

The exterior paint film on steel-lined plastic tanks is too thick during spraying. Generally, the thickness of the epoxy asphalt exceeds 120μm, and it will typically crack.

2. The surface roughness of the tank is too low, especially around the welds, which often leads to uneven roughness.

3. In comparison, the outside, which has a higher humidity and relatively poor ventilation, solidifies quickly, which also leads to the emergence of film cracking.

The above three factors are the causes of paint layer peeling and cracking; only by understanding the causes can we better target our preventive measures.
