Paper

Silicates have a wide range of uses in the paper industry. Apart from serving as a key auxiliary material in cellulose bleaching and waste paper recycling, they are also used as an adhesive in cardboard manufacturing.

 

Cellulose/groundwood bleaching

Sodium silicates are used as bleach stabilizers and activators for the hydrogen peroxide bleaching of cellulose.

INOPLEX silicates differ from standard silicates in that they are specially configured for use in pulp bleaching.

Deinking

Sodium silicates are a key auxiliary material in waste paper recycling. In their standard form, they boast a long track record of proven performance.

For deinking and flotation applications, vanBaerle purpose-developed the INOPLEX product line. INOPLEX silicates differ from standard silicates in that they are specially configured for use in paper recycling.

Cardboard roll adhesive/cardboard

Silicate adhesives are water-based materials and lend themselves to applications requiring high mechanical and bonding strengths.  

The silicates are able to penetrate the surface and dry to form a solid, inorganic, hardwearing adhesive bond. The resulting silicate films are heat- and chemical-resistant.
