Introduction to low aluminum silica aluminum gel I

Low aluminum silica-alumina gel, as a special silica-alumina gel product, its characteristics and applications mainly revolve around its low aluminum content. The following is a detailed introduction to the knowledge of low-aluminum silica-alumina rubber products:

1. Product Overview

Name: Low Aluminum Silica Aluminum Gel

English name: Alumino sillica gel (the specific name may vary depending on the product)

Appearance: Usually yellowish, granular gel

Chemical formula: It can be expressed as mSiO2·nAl2O3·xH2O, where m, n, and x represent the relative proportions of each component. The n value in low-aluminum silica-alumina glue is relatively small, that is, the aluminum content is low.

2. Main features

Stable chemical properties: Low aluminum silica-alumina glue has stable chemical properties, does not burn, and is insoluble in any solvent except strong alkali and hydrofluoric acid.

High-temperature stability: Even under high-temperature conditions, low-aluminum silica-alumina glue can maintain good stability and is not easy to deform or lose its physical properties.

Pore structure: It has a porous structure and a large specific surface area. This characteristic makes it have strong adsorption capacity.

Water absorption: It has strong moisture absorption capacity, especially under high humidity conditions, its adsorption capacity is significantly higher than that of fine-porous silica gel, so it is very suitable for use as a moisture adsorbent or humidity regulator.

Low aluminum content: Compared with ordinary silica-alumina gel, the aluminum content in low-aluminum silica-alumina gel is lower, which may affect some of its physical and chemical properties, such as adsorption performance and catalytic activity, but may also affect some specific has advantages in application.
