PTFE Lined Storage Tank for Ammonium Fluoride

Core Product: Featuring RANA PTFE-backed fiberglass liner as the core material, this solution addresses the corrosive nature of ammonium fluoride (NH₄F) – which hydrolyzes to produce hydrofluoric acid. Through a thermal compression lamination process, the liner achieves seamless integration with the tank body. The PTFE's exceptional corrosion resistance completely withstands both the fluoride and its hydrolyzed byproducts, ensuring safe storage.

Product Introduction

Competitive Edge: The company holds patents including "Manufacturing Process for Large Chemical Equipment and Its Corrosion-Resistant Inner Liners", with products demonstrating world-leading resistance to ammonium fluoride corrosion (unchanged after 3 years of immersion in 40% ammonium fluoride solution). As a member of the China Semiconductor Industry Association, its linings are manufactured in cleanrooms (the largest in the domestic industry at 9,000㎡) to prevent particulate contamination, meeting stringent requirements for electronic-grade ammonium fluoride storage.

Application scenarios: Primarily serves high-end manufacturing sectors including semiconductors and photovoltaics. In semiconductor wafer cleaning processes, this storage tank ensures stable preservation of high-purity ammonium fluoride solution, preventing metal ion contamination on wafer surfaces. During photovoltaic cell etching stages, its advanced high-purity lining technology guarantees solution purity, thereby enhancing the photovoltaic conversion efficiency of solar cells.
