Alumina is widely used in medicine, microelectronic materials, biofilms, catalysis, optics, etc. because of its peculiar properties such as surface charge properties, thermal conductivity, mechanical properties, high temperature resistance, stability, etc., but the obtained alumina has surface charge. Uneven distribution, poor dispersion, and uneven particle size defects affect the application of alumina.So we need some modification methods to solve this problem, our company's modification machine is just right, our stone grinding mill is also convenient for you to grind alumina.

Modification of alumina powder by modifier

The continuous powder surface modification machine is a deep processing equipment developed by shanghai Clirik, which is specially developed for various inorganic powder surface treatments. It has high production efficiency, advanced technology, low unit energy consumption and convenient maintenance.

Surface coating of alumina powder on polyethylene glycol

Surface electronegativity is an important property of alumina in many fields, but its electronegativity is defective. Therefore, a commonly used non-polluting surface modifier is selected to improve the charge performance of the alumina surface. A macromolecular organic polyethylene glycol (PEG) having a long chain or branched structure therein is often used as a surface modifier.
