Improving safety and cleaning work efficiency - Underground tank FRP lining
When cleaning the inner surface of the raw material underground tank, it was being washed with factory water pressure, but there was a problem with poor dirt removal, making cleaning difficult. Additionally, due to the acidic nature of the raw materials, the existing resin coating was prone to peeling, which could lead to the underlying concrete corroding. Issues: 1. Generally, using a high-pressure washer can apply too much pressure, causing the resin coating to peel off. 2. It takes a considerable amount of time to clean (over 2 hours). *Neglecting cleaning can lead to corrosion and aging of the underground pit tank due to hydrogen sulfide and other factors. If left unattended, this can result in the leakage of hazardous materials, leading to serious environmental issues.

basic information
We propose the use of FRP lining (Fiber-Reinforced Plastic) that is strong and acid-resistant. FRP lining made with resins and glass mats excels in water resistance, chemical resistance, and acid resistance, protecting concrete and steel from rust and corrosion. Points: 1. The FRP itself has strength, allowing the use of high-pressure washers. 2. Using a high-pressure washer allows for quick cleaning. 3. It is also excellent in acid resistance, making it less prone to corrosion. This time, we carried out the work using the HL method. * Cleaning → Drying → Filling uneven areas with putty → Applying primer → FRP lining → Top coat.
