Material properties 

• Temperature resistance: Long-term temperature range of -20 to 120℃. Short-term at 140℃, the material will not deform and will not crack at low temperatures. 

• Corrosion resistance: pH 2 - 12. Resistant to strong acids, strong alkalis, salt spray, and chemical solvents; Vinyl FRP is suitable for strong corrosive environments. 

• Mechanics: Fiberglass reinforced, resistant to pressure, water flow impact, and does not collapse when stacked. The strength is three times that of PVC. 

• Heat exchange hydrophilic: The formed corrugated water film is uniform, with a specific surface area of 220 to 300 m³/m³, a porosity of 91% to 94%, and moderate air resistance. 

• Flame retardant and anti-aging: Oxygen index ≥ 32 (B1 level flame retardant); With the addition of UV additives, the lifespan is 8-10 years indoors and 6-8 years outdoors. 

• Shortcomings: The weight is greater than that of plastic fillers, and the procurement cost is higher.

Standard specifications (complying with GB/T 7190 and DL/T 742)

1. FRP corrugated packing (S-wave/triangular slant wave)

• Standard module: 500×1000/1200/1500mm, module height 500mm

• The plate thickness is 1.5 to 3 mm, the wave height is 32 mm, and the plate spacing is 32 to 35 mm

Production Process Description

• Ingredients: Unsaturated polyester/vinyl resin + alkali-free fiberglass mat + flame retardant, hydrophilic, UV-resistant additives

• Process: Raw material impregnation and mixing → High-temperature mold forming (corrugated/honeycomb) → Constant-temperature curing → Edge trimming and polishing → Hydrophilic surface treatment → Module bonding → Finished product inspection and packaging

• Technical Advantage: One-piece molding without delamination, long-term hot water resistance without hydrolysis, stable structure

Structural Description

• S-shaped corrugated packing (counterflow tower): Interlaced concave-convex flow channels for thorough countercurrent contact between water and gas; self-supporting ribs at the base, modular assembly

• Hexagonal honeycomb packing (compact high-temperature tower): Vertically connected hexagonal holes, large heat exchange area, small footprint

• Complement: Matching FRP corrosion-resistant brackets, FRP water collection devices, and a unified full-tower corrosion-resistant system

Installation Instructions

• Early stage: Clean the support beams inside the tower, level the FRP brackets, and remove oil stains and debris

• Prefabrication: Ground adhesive filling module, let it stand and cure for 24 hours before lifting

• Laying: staggered placement from bottom to top to prevent seamless joints; Gap between packing and tower wall ≤ 20mm

• Fixed: Stainless steel threaded rod locking interlayer; Homework must be paved with boards, and it is strictly prohibited to step on the filling material directly

• Direction: The corrugated guide surface is facing upwards to ensure even water distribution; Use nylon sling for lifting

Application scenarios

• Chemical, pharmaceutical, electroplating: acid alkali, high salt, organic solvent circulation cooling

• Power plants, metallurgy, forging: 80-110 ℃ high-temperature turbid water cooling

• Garbage incineration and heat treatment workshop: high temperature, oily and corrosive water quality

• Northern cold factory area, closed high-temperature cooling tower
