FRP Mixed Acid Waste Acid Tank
FRP mixed acid waste acid tank is a special storage container made of glass fiber reinforced plastic (FRP), mainly used for the storage and treatment of corrosive mixed acid and waste acid in chemical, electroplating, metallurgy and other industries. Compared with traditional metal storage tanks, FRP mixed acid waste acid tank has excellent corrosion resistance, light weight, high strength, long service life and other characteristics, and has become the preferred equipment for acid medium storage in modern industry.
Features & Advantages
Excellent corrosion resistance
can withstand a variety of mixed acid environments (such as sulfuric acid, hydrochloric acid, nitric acid and other mixed acids), has good resistance to complex components in waste acid, and has a wide range of pH values (1-14).
Excellent physical properties
high strength: tensile strength can reach 200-300MPa, light weight: only 1/4-1/5 of steel containers, anti-aging: adding anti-ultraviolet agents can extend outdoor service life.
Good performance
smooth inner wall, not easy to scale, easy maintenance, local damage can be repaired on site, good insulation performance, non-conductive.
Environmental protection characteristics
no leakage design, avoid secondary pollution, materials can be recycled, and little pollution during the production process.

Production Process
Raw material selection
Resin matrix: usually choose vinyl ester resin or bisphenol A type unsaturated polyester resin with excellent corrosion resistance
Reinforcement material: medium alkali or alkali-free glass fiber cloth, glass fiber mat and surface mat
Auxiliary materials: curing agent, accelerator, anti-ultraviolet additives, etc.
Molding process
Core mold preparation
Lining anti-corrosion layer: resin and short-cut fiber are sprayed at the same time
Structural layer winding (cross winding or hoop winding)
Curing demoulding
Accessory installation
Special process treatmen
Inner lining anti-corrosion layer: adopts resin-rich layer design, and the resin content is more than 70%
Structural reinforcement: key parts adopt reinforcement rib design
Anti-seepage treatment: multi-layer anti-seepage structure design
Quality inspection: including electric spark detection, ultrasonic detection, etc.
Selection and Use Precautions
- Selection considerations: composition, concentration and temperature of storage medium
Environmental conditions for use (indoor/outdoor)
Volume requirements and site restrictions
Requirements of relevant industry standards - Installation requirements: The foundation should be flat and solid, well ventilated, and away from fire sources and high-temperature areas
- Use and maintenance:
Check the tank condition regularly, avoid mechanical impact, clean up sediments in time, and pay attention to antifreeze in winter. - Safety precautions: Set up anti-overflow facilities, equip with necessary safety signs, operators should wear protective equipment, and formulate emergency plans.
With its unique performance advantages, FRP mixed acid waste acid tank will play an increasingly important role in the field of industrial corrosive medium storage, providing reliable guarantee for safe production and environmental protection in various industries.
