Case Study: Chemical Plant Scrubber Tower Retrofit
Application: Outdoor Wet Scrubber & Spray Absorption Tower
A chlor-alkali production facility operating outdoor hydrochloric acid mist scrubbers in extreme tropical conditions, exposed to high UV radiation, acid spray, salt fog, and daily temperature fluctuations.
Standard PP sheets showed chalking, micro-cracking, and progressive embrittlement within 2.5–3 years under combined UV and sulfuric acid mist exposure. Repeated failures caused unplanned shutdowns at over $45,000 per tower every three years.
UV-Induced Embrittlement & Thermal Fatigue Failure
Deployed QEEHUA anti-UV modified PP sheets in 20mm heavy-gauge format with proprietary segmented cooling for superior flatness. Paired with motorized butterfly valves for automated flow regulation across the scrubbing circuit.
15-Year Service Design & Zero-Warp Structural Integrity
Service life extended from 3 to 8–15 years through proprietary UV stabilizers that prevent polymer chain scission and surface degradation.
Segmented cooling ensures heavy-gauge 15–25mm sheets maintain absolute flatness, eliminating panel deflection under thermal cycling.
Pain Points & Strategic Solutions
UV Material Aging
Standard PP sheets exposed to intense UV radiation may experience surface degradation, discoloration, and reduced mechanical performance over time, affecting outdoor scrubber reliability.
QEEHUA anti-UV PP sheets incorporate UV-resistant formulations to improve weather durability and maintain stable mechanical performance in outdoor chemical treatment applications.
Structural Warpage——Segmented Cooling Process
A controlled staged cooling process reduces internal stress in heavy-gauge 15–25mm PP sheets, ensuring excellent flatness and dimensional stability across large tower panel spans.
Chemical Mist Corrosion
Excellent resistance to hydrochloric acid, sulfuric acid, and acid mist exposure, providing reliable surface performance in demanding industrial scrubbing applications.
Thermal Cycling Endurance
Withstands UV exposure, temperature changes, and acidic mist in outdoor scrubber applications.
Anti-UV PP sheets provide stable long-term performance in harsh chemical environments.
Industry Requirements
UV Weathering Resistance
Anti-UV PP formulations improve resistance to photo-oxidation, helping maintain surface quality under prolonged outdoor exposure.
Heavy-Gauge Rigidity
15–25mm PP sheets provide high stiffness and dimensional stability for large industrial scrubber structures.
ISO 9001 Certified
Controlled manufacturing processes and material traceability ensure consistent sheet quality across production batches.
8–15 Year Service Life
Designed for reliable operation under UV radiation, salt fog, acid mist, and temperature cycling conditions.
