Active Alumina Balls Categories: Mainly divided into three types, namely, air separation carrier type, purification type, and defluorination type.
1. Oxygen-nitrogen separator carrier type, this variety has an AL2O3 crystal phase structure of x-ρ, and is a white, spherical, porous material. The pores are evenly distributed, with a large surface area and high strength, strong water absorption, and is a stable new desiccant. Mainly used for pressure swing adsorption gas dehydration, oxygen production in air separation units with polypropylene drying, and can ensure an improved purification and separation effect of the molecular sieve on the gas.

2. Purification and Fluoride Removal Type, High Fluoride Water Fluoride Removal Type - A white spherical particle with uniformly distributed pores, non-toxic, odorless, non-powdery, non-fragile, easy to regenerate, and long-lasting, it is a stable new type of fluoride removal agent. Mainly used for fluoride removal in drinking water, with an adsorption capacity of up to 2.4mg/g, its fluoride removal effect is quite remarkable. The purification type crystal phase structure is r, which is a white spherical particle or powder. With uniformly distributed pores, large volume, strong water absorption, low specific gravity, and low wear, it is a stable new type of desiccant. Mainly used for air purification, capable of removing impurities such as water and acids.
