Product Introduction
Inert alumina balls are a type of catalyst support and packing material. They have stable chemical properties, good acid and alkali resistance, and high strength. They are widely used in chemical fields such as ammonia synthesis converters, petroleum chemical hydrogen plants, hydrogen peroxide plants, and oxygen production industries. Product implementation standard: HG/T3683.1-2014.
Product Features
Inert alumina packing balls have excellent acid resistance and heat resistance.
Inert alumina packing balls are characterized by high purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal stability, and stable chemical properties.
