Description:

The Actived Alumina is a good packing media as air & gas desiccant/dryers for distillation plant and other chemical process. The Activated Alumina Ball is applied for absorption the water and TBC (Tert butyl catehol) to purify the styrene, butadiene, cyclohexan, etc. during production. So not only this ball has the same characteristics of heat resistance and high mechanical strength as inert alumina ball, but also it can function as desiccant, filter, disperser of liquid and vapor, cover and support for catalyst.

Applications:

Reactive Aluminas are a fundamental component of high quality shaped and unshaped (monolithic) refractory products.

The fully ground reactive aluminas are especially beneficial for the production of high performance refractories where defined particle packing, rheology and consistent placement characteristics are as important as the superior physical properties of the final product.

Mono-modal reactive aluminas provide the full flexibility in designing the refractory matrix particle size distribution. Multi-modal reactive aluminas can further enhance the performance by optimising the particle size distribution and due to the intensive homogenisation of the super-fine components during co-grinding. CTC 50 and CTC 55 have advantages especially for self-flowing castables. E-SY 1000 and E-SY 2000 contribute to a low dilatancy of castables, which makes them easy to use and to handle.

Advantages:

Reduced water demand Low open porosity Excellent sinter reactivity Excellent wear resistance and mechanical strength Excellent high temperature mechanical performance Especially benefit self-flowing castables Reactive alumina is a key component to achieve soft castable consistency at very low dilatancy Low dilatant mixes allow use of low power mixing equipment and a mix consistency for being shoveled Support silica-free pumpable mixes with superior hot properties, valued as a high performance ladle lining by shot-creting and other applications
