3) Reclaiming agent for de-acidic in transformer oil, and de-arsenic agent in the Acid industry

4) Adsorbent in the production of hydrogen peroxide solution

5) Catalyst for polyhydro-ammonia by substituting silica gel with ball-shaped product

6) Desiccator and purifying agent.

Application

1. used for reclaiming degradation product in the working fluid in hydregen peroxide production by anthraquinone method, especially in the plants of palladium catalyst and three-componet nikel catalyst.

2. used for deep drying of gas or liquid phase of petrochemicals and adsorption drying by automatic instruments.

3. used as defluorination in production of alkylbenzene or fordefuorainting in drinking water. It has been used by some home factories and approved that it accords with the technology demands perfactly.

Advantage

High wear-resistance:
The alumina balls’ wear-resistance is higher than the common alumina balls’. When it is working, the ball won’t pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.

High density
The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.

Available Sizes: 2mm-4mm, 3mm-5mm, 4mm-6mm, 5mm-7mm.
