Flotal® is an ideal choice for interior applications for making small rooms seem larger, brighter, higher and deeper.
Offering perspective and a new dimension to interior spaces, it is intended for applications in bathrooms, bedrooms, kitchens, stores, sport centers, exhibition centers and kindergartens.
As in flat glass, Flotal®can be cut manually or at the cutting table.
Cutting is the first step of mirror processing. Cutting oil is as important as the cutting diamond (cutting wheel).
Cutting oil used during mirror processing serves many purposes such as;
As a general rule, volatile cutting oil is used for cutting mirrors. Dry or non-volatile cutting oils used for cutting, may cause faults especially at the edges of the mirror.
For the cutting oil includes solvent, the mirror panes should not get into contact with each other when stacking after cutting. The cut size panes should be interleaved with plastic spacers (such as cork) providing the rest of the cutting oil on the mirror to evaporate rapidly.
Edge working processes such as;
can be applied. After each process Flotal® should be washed and the water on the mirror should be removed completely.
Grinding and bevelling processes are grinding of the mirror (glass) edges with diamond wheels. During the grinding process, micro cracks may occur on the painted, copper and silver coated layers of the mirror. These cracks will become larger when inappropriate wheel is used and motor with low speed rate is attached to the wheel. Diamond particle size of the wheel should not be thicker than D=65. Motor speed rates should be at least 2500 rpm. When the diamond wheel is renewed, for the first ½ and 1 hour, it should be used only for grinding the glass edges to protect the coating of the mirror.
Processing wheels are cooled by using coolant agent added water. With these cooling solvents the mechanical stress applied to the mirror edges is minimized and a smooth abrasion is provided. Excessive mechanical stress deteriorates the coated layer and as a result, water and glass dust penetrates between the glass and the coating causing the edge corrosion to begin. During the grinding of the edges, glass particles (dust) causes the pH value of the processing water to rise above 10. Alkaline cooling water with high pH value is the reason for the edge corrosion. The rise in pH value should be avoided by using compatible cooling agents to provide the pH value to be lower than 9. Right after the processing, the mirror should be washed to remove the glass dust (particle) and the cooling water, before drying on the surface of the mirror.
Coolant agent added water used for processing includes sulphate ions. During the process various bacteria are occurred. While reducing the sulphate ions, these bacteria produce sulphur gas in time. Hydrogen sulphur gas causes the silver coating of the mirror to darken. This is prevented by adding appropriate biocides into the cooling water. The bacteria will develop immunity when biocide used regularly. Therefore if the number of bacteria is high then quick freezing should be applied.
It is possible to deposite and to remove the glass particles occurred during grinding and beveling. Proper flocking and hydrocyclone systems are used for this purpose. The depositing agent should not be highly acidic and should not contain chloride. Besides, the depositing agent should not react with the coolant. After the grinding and bevelling processes, mirrors should be washed before the solvents on the surface of the mirror dry. Therefore the corrosive effect of the solvents used for processing is prevented.
Megerle in Germany claims that they produced a transparent paint aiming to avoid liquid and vapor penetration from the micro cracks occurred during the edge processing. Also it is reported that this paint is used in Germany especially for applications in bathrooms with washbasin units. To prevent the corrosion on the bottom edges of the mirror close to the washbasin, clear and transparent paint is applied to the processed edge of the mirror by a sponge with stripes.
Flotal® should not be cleaned with chemical detergents.
