Acenol PG is a powder flocculant for the complete removing of glass particles from the grinding solution while processing glass. It can be easily dosed to the grinding solutions and is virtually dust free. It is used on commercially available as well as suitable self-constructed flocculation systems equipped with a powder dosage device and a corresponding stirrer. It also flocculates itself completely in aqueous solutions even if there are no glass fines. As a result, the danger of overdosing is virtually excluded (repeated overdosing over a longer period should yet be avoided). Acenol PG must be added to the grinding solution only as a powder! Acenol PG was specially adapted to our coolants (Acecool) in order to guarantee that the coolant solutions are not affected adversely by the flocculant. Before using Acenol PG with other coolant concentrates our application laboratory should be contacted.

Acenol PG is added directly into the flocculation tank filled with grinding solution by means of a screw conveyor combined with a vibrator under stirring. Flocculation starts after approx. 1.5 - 2 minutes and is finished after 6 - 8 minutes. During this period continuous stirring is necessary. When the stirrer is stopped, the flakes start settling. After about 8 - 10 minutes a sludge phase is formed which can be removed by means of a scraper or by draining and filtration. Normally, the sludge phase is filtrated (e.g. by vacuum filtration or chamber filter press) and the clean coolant solution is fed back into the circuit.

For initial tests, we recommend to use 200 grams Acenol PG per m3 grinding solution. Depending on the type and amount of glass fines and the desired degree of purity of the grinding solution the use concentration can be varied (the higher the amount of glass particles the higher in general also the amount of Acenol PG). However, the used amount should not drop below of 100 grams per m³ and a quantity of 400 grams per m³ should not be exceeded. According to our experiences the average use concentration is between 150 - 200 grams Acenol PG per m3 grinding solution.

If no flocculation plant is available, a manual processing of the individual tank can also be carried out. For this at the end of the workday a slight amount of Acenol PG is scattered onto the surface of the grinding solution and left overnight. A partial cleaning of the grinding solution is achieved by this procedure; furthermore, removing the glass sludge from the tank is also clearly facilitated.

Safety instructions for the handling can be found in the Material Safety Data Sheet. Stored in well-closed containers at temperatures between 5 and 40 °C the minimum shelf life of Acenol PG is 6 months. Store in a dry place.
