What is the difference between zirconia and alumina grinding media?

Yttria-stabilized zirconia beads typically have a density of about 6.0 g/cm³, compared with about 3.6 g/cm³ for high purity alumina. The higher density delivers more impact energy for fine and nano grinding with very low wear, which suits electronic materials, battery materials, inks and coatings. High purity alumina media are more cost-efficient and ideal where trace alumina is harmless, such as ceramics, glazes and alumina-based materials.

Which molecular sieve type should I choose?

4A molecular sieve is used for general gas and liquid drying and for removing water, ammonia and methanol from gas streams. 5A is used in PSA oxygen generators and normal-paraffin separation. 13X has the largest pore opening of the three and is used for air pre-purification (removing H2O and CO2) and as a catalyst carrier. Share your gas composition, pressure and dew point target for a specific recommendation.

What do G3 and G5 grades mean for ceramic bearing balls?

Ball grades defined by ISO 3290 and ABMA standards specify the allowable deviation in sphericity, diameter variation and surface roughness; a lower number means higher precision. G3 and G5 silicon nitride or zirconia balls are used in high-speed spindles, robotics joints, precision instruments and electric motors where low friction, electrical insulation and long service life are required.

Product Description

Applications

It can be widely used in the deep drying of petroleum cracking gas, ethylene propylene gas, hydrogen production, air separation unit, instrument air dryer and fluoride treatment in dioxygen water.
It can also remove sulfur gas hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbon and other pollutants in the waste gas, especially suitable for the defluorination treatment of water containing fluorine.

Activated alumina (molecular formula Al2O3-x(OH)2x, 0<x<0.8) is one of the most widely used inorganic chemical products in the world. Activated alumina has large activity due to its porous structure, high specific surface area and unstable transition state. It is widely used as catalyst and catalyst carrier in petrochemical and fertilizer industry. Activated alumina also has adsorption properties, so it is used as a desiccant of gas and liquid, an adsorbent for gas purification, a defluorination agent for drinking water, and a color and odor elimination agent for industrial sewage. The main industrial activated alumina products available today are produced by rapid dewatering. Activated alumina refers to calcined alumina after full fine grinding, with α-Al2O3 of primary crystal size 1μm as the basic composition (20% to 90%).

Regenerant using sodium hydroxide solution, can also use aluminum sulfate solution. The solution concentration of sodium hydroxide regenerant is 0.75% ~ 1%, and the consumption of sodium hydroxide can be calculated according to the 8 ~ 10g solid sodium hydroxide required for removing 1g fluoride, and the amount of regenerated liquid is 3 ~ 6 times the volume of filter material. The solution concentration of aluminum sulfate regenerant is 2 ~ 3%, and the consumption of aluminum sulfate can be calculated according to 60 ~ 80g solid aluminum sulfate for every 1g fluoride removed.
