Attention should be paid to several aspects when paving ceramics on electrothermal?films: first, is waterproof insulation should deal be well prepared; second, the concrete used to pave ceramics should not be too thick. The thickness should be controlled within 50mm (the thickness of concrete and ceramics
In fact, the steps are very simple. First, pave insulation boards on the ground. Second, put the electrothermal?films into moisture barrier bags and pave them hermetically. Then, pave packaging layers, backfill with cement cushion?ply. Finally, operate according to the common room decoration, lay tiles. After finishing above four steps, the laying of tiles in room with electrothermal?films are finished.
Attention should be paid to several aspects when paving ceramics on electrothermal?films: first, is waterproof insulation should deal be well prepared; second, the concrete used to pave ceramics should not be too thick. The thickness should be controlled within 50mm (the thickness of concrete and ceramics, such thickness is convenient for heat transfer); third, expansion joints of ceramics must be retained(because floor heating system will lead to heat expansion and cold contraction); fourth, the temperature increases slowly which avoids expansion caused by excessive heat; fifth, the electrothermal film power should be controlled within 80W/square meter in accordance with the room size; sixth, load must be calculated before the installation of temperature controller so as to avoid the line fault of temperature?controller; seventh, phase line must be allocated reasonably in accordance with the inlet wire of the room(now the inlet wire uses three-phase four-wire system) so as to save energy, electrothermal film input lines in several rooms should be separately connected to inlet wire, and single-phase overload should be avoided. Remarks： Electrothermal membrane belongs to safety facilities, so the quality of products is in the first place(good quality of electrothermal film, high temperature resistant power line, multi-strand wires and joints should be welded, insulation treatment should be carried out after welding, and luted with glue) and construction quality is in the second place, consider, it should be no risk at all.
