As a matter of routine, the acidity of our Tonsil bleaching earths is also inspected. To do this, the residual acid content and the pH value of the aqueous extract is determined. Usually, the pH value is located in the weak acidic range, special qualities may deviate from it.

The humidity of Ihe Tonsil leaching earths is adjusted to 3-9% in our combined grinding and drying facility, and checked on every single consignment at the goods dispatch inspection. If specially requested, a determination can also be made using the Karl Fischer titration method, which, in terms

The Bleaching Activity of a Specific Toasil quality should, as far as possible, remain constant. Guaranteeing this is one of our most important tasks. To determine whether this is being done, bleaching tests are carried out for comparison with a standardised bleaching earth and the bleaching e

Melamine was first synthesized in 1834 by the German chemist Justus von Liebig. In early production, calcium cyanamide was first converted to dicyandiamide, and then it was heated above its melting temperature to produce melamine. Today, most industrial manufacturers use urea to produce melamine in

Various excellent properties make polyvinyl alcohol one of the most popular substances in the world. There are two important indicators of polymerization degree and alcoholysis degree. The textile industry uses slightly lower polymerization degree, the adhesive industry uses high polymerization degr
