Special requirements for geothermal floor pavement
Ground handling before installation should be detailed The ground must be level within a radius of 2 meters, and the height difference must not exceed 3mm. The ground must be completely dry. Before laying the floor, a geothermal heating test must be performed. The inlet water temperature should be at least 50°C to ensure that the heating system operates normally. And to keep warm for more than 24 hours to make the ground dry, to ensure that the moisture content meets standards. The most important details of the installation process, the order of stress It is best to use a suspension type installation method. The floor is closely attached to the ground through the cushion material, there is no gap between the floor and the surface, and more shrinkage gaps are reserved between the floors. Since the amount of tidal gas released by hydrothermal radiation is large, it is necessary to work hard to prevent moisture. When paving, you must first clean the floor. Pay attention to clean the corners and ensure that there are enough expansion joints. The second step is to lay a layer of plastic cloth on the ground to cut off the moisture. The plastic sheet should be 10cm above the ground at four corners. The third step is laying floor mats. Be careful to leave expansion joints, overlap at least 5cm at the interface, and must be sealed with tape. Use a skirting board that is thicker than a normal floor and use it separately. The floor can only warm up after 24 hours of installation. In order to facilitate heat conduction, the cushion material should not be too thick. In addition, the use of special geothermal floor glue; can not be paved; can not play keel, because this will leave air between the gap, the air's low thermal conductivity, is not conducive to heat transfer. Use special paper mats to avoid distortion The floor mat between the floor and the floor can not use the ordinary foam floor mat, must use the geothermal special paper floor mat, because this type of floor mat has fast heat conduction and does not deform. Ordinary foam mats have low thermal conductivity and are exposed to high temperatures for a prolonged period of time, and are prone to harmful gases that endanger the health of users. Surface temperature during construction cannot be too high Whether it is a hydrothermal radiation heating system or a cable heating system, do not produce stoves, electric furnaces, etc. on the ground. If the surface temperature is too high, the aluminum-plastic composite pipeline under the ground may melt. Nature floor del floor
