Sandwich panels are used for thermal and acoustic insulation of facades and roofs of industrial, commercial, residential and agricultural buildings; chambers, cold rooms, walls of isothermal trucks; boats and offshore platforms; photovoltaic, solar thermal and wind power plants and greenhouses.
TNN FLAT, equipped with high temperature resistant ceramic electrodes, is available for top or bottom treatment of metal sheet. The open design facilitates all maintenance operations and a special system makes it easy to lift the electrode assembly.
The air gap (the space between the electrode and the substrate to be treated) is automatically adjusted according to the thickness of the sheet metal.
TNN FLAT is equipped with a stainless steel discharge plate to avoid jamming of the sheet, which may be curved.
Advantages of corona treating sandwich panels’ sheets
- Allows polyurethane foams to adhere firmly to even the most difficult surfaces
- Prevents delamination of polyurethane foam
- Improves mechanical strength and durability
- Prevents cracking, delamination or separation between layers
