Polishing powders for glass processing

The polishing powders for flat glass processing are used in three different cases.

1. Bevel polishing: in this case the operator or the machine uses a felt (or other material as polyurethane) on which is send a mixing with water and the polishing powder. It is the only way to obtain a perfect bevel polishing on flat glass.
2. The scratches removal: here you have to give again to the glass its former transparency which was cancelled by the abrasive products used to remove the scratches.
3. The glass surface cleaning before a following processing.

To carry out this metallic oxides, natural or not are used, the most known is the cerium oxide (the cerium is a chemical element from the rare earth family).

Polishing products characteristics

1/The product must be mixed with water

These products are generally mixed with water which acts as cooling product. Some additional products are added to the polishing powders to give a good mixing.

2/It must not glue at the back of the tank during the production stops

The polishing powders have to be quickly mixed with the water when the production starts again.

3/They must not be degraded by bacterium

A polishing devices not used for a period (holidays..) can be polluted by bacterium.

4/They have to be efficient for a large temperature scale (from some degrees up to 40 degrees Celcius)
