How Are Dual Laminate Tanks Made?

May 25, 2023

Dual Laminate tanks have gained significant recognition in various industries due to their exceptional corrosion resistance and durability.

In this article, we’ll talk about the manufacturing process of Dual Laminate tanks, from the selection of materials to the final product.

We will also highlight the advantages of Dual Laminate tanks over other alternatives, making them an excellent choice.

1. Material Selection

The manufacturing process of Dual Laminate tanks begins with the careful selection of materials.

It combines thermoplastic liners (such as polyvinyl chloride (PVC) or polypropylene (PP)), with the structural strength of fiberglass reinforcements.

The liners provide excellent corrosion resistance, while the fiberglass reinforcements offer structural integrity and durability.

2. Mold Preparation

Once the materials are selected, the next step involves preparing the mold for the Dual Laminate tank.

The mold is typically made from materials like fiberglass, steel, or aluminum.

Proper cleaning and treatment of the mold surface ensure smooth demolding and a high-quality tank finish.

3. Liner Application

In the manufacturing process, the thermoplastic liner is first formed and welded to create the tank’s inner surface.

The liner is carefully fitted within the mold, providing an impermeable barrier against corrosive substances.

The liner’s thickness and composition are tailored to the specific requirements of the application.

4. Layering and Resin Application

After the liner is in place, layers of fiberglass reinforcements are added to the mold.

These reinforcements provide structural strength to the tank.

A combination of resin and catalyst is then applied to saturate the fiberglass layers. This creates a strong bond between the liner and the structural laminate.

5. Curing and Consolidation

The tank assembly goes through a curing process to allow the resin to harden and bond with the fiberglass reinforcements.

This step ensures the consolidation of the entire structure.

The curing process may involve applying heat and pressure to optimize the mechanical properties of the Dual Laminate tank.

6. Trimming and Finishing

Once the tank has cured, it is carefully removed from the mold.

Any excess fiberglass and uneven edges are trimmed, and the tank’s surface is prepared for finishing touches.

This may include sanding, buffing, or applying a protective coating to enhance the tank’s appearance and resistance to UV radiation.

Benefits of Dual Laminate Tanks

– Superior Corrosion Resistance: Dual Laminate tanks combine the chemical resistance of thermoplastic liners with the structural strength of fiberglass. This provides exceptional corrosion resistance to a wide range of aggressive substances.

– High Strength and Durability: The integration of fiberglass reinforcements ensures the tank’s structural integrity. This makes it capable of withstanding high internal and external pressures.

– Versatility and Customization: Dual Laminate tanks can be customized to meet specific project requirements, including size, shape, and configuration. This flexibility allows for optimal design solutions for various applications.

– Long Service Life and Low Maintenance: Dual Laminate tanks offer a long service life with minimal maintenance requirements. The materials used are resistant to degradation, resulting in extended durability and cost savings over time.

The manufacturing process of Dual Laminate tanks involves a careful selection of materials, mold preparation, liner application, layering and resin application, curing and consolidation, and trimming and finishing.

Dual Laminate tanks provide a unique combination of corrosion resistance and structural strength, making them ideal for applications in various industries.
