Difficulties in renovation: Building materials market, a variety of solid wood flooring, laminate flooring, bamboo flooring, etc., itself dazzling, coupled with the sales staff of the business are introduced, their floor suitable for "geothermal", there are It simply said that it was the "dedicated conservatory" floor. I really didn't know who the letter was. So, how should we choose a geothermal floor?
Misleading construction of geothermal floor The Ministry of Construction had proposed that the ground-based low-temperature radiant heating system should be strongly advocated. The introduction of this measure has caused many brands of geothermal floors to appear on the market one after another. However, since China does not have relevant standards for floor heating systems and there is no standard for floor heating, it has allowed some companies to take advantage of this.
The reporter saw in a medium-sized building material home improvement market that although there are more than 50 floor manufacturers, they all claim to be able to use geothermal energy. In fact, according to Gao Zhihua, an expert from the Wood Flooring Committee of the China Timber Distribution Association, 55% of these can't be used in heating systems, and 25% can be used for floor heating, but the effect is not ideal. Only 20% are dedicated floor heating systems. . Therefore, to remind consumers to pay special attention to certain misleading claims: If the thicker wood flooring "the thicker the better the feel", "the thicker the more thermal insulation", special geothermal floor foam pad, aluminum foil on the back, on the packaging box It is the geothermal floor that is printed with "heating room only." As everyone knows, these arguments are unreasonable; they only affect the cooling of the ground.
How to choose geothermal floor Because of the special characteristics of geothermal heating, the requirements for the floor are very strict. Therefore, in addition to meeting the conventional quality indicators, the geothermal floor must meet the following four requirements:
Thermal conductivity is better - should not be thin thick. Both wood and bamboo are good natural materials. The ground heat is transmitted to the surface through the floor and there is bound to be heat loss. The ideal floor can minimize these losses. Therefore, in order to reduce the loss of thermal energy and reduce the heating operation and maintenance expenses, the floor heating floor must be "thickness is not selected thick." Optional multi-layer solid wood, bamboo flooring and laminate flooring, the thickness of not more than 8 mm, the maximum can not exceed 10 mm.
The dimensional stability is better—it should not be big. The use environment of the geothermal floor is quite complicated, especially in the northern areas, the ground during the non-heating season is subject to various kinds of moisture, and the temperature of the ground during heating is suddenly increased, and the wooden floor is bound to undergo double changes of “temperature†and “humidityâ€. Therefore, geothermal flooring must be purchased with good stability, such as laminate flooring, multi-layer solid wood flooring, bamboo flooring, these integrated composite flooring.
Moisture and heat resistance is better --- suitable for environmental protection plastic. Integrated composite flooring uses adhesives. The adhesives must meet the three criteria of environmental protection, bonding strength, and high temperature and humidity resistance. In particular, for geothermal floors, it is necessary to go through experiments such as high humidity resistance and low temperature resistance. If ordinary adhesives are used, environmental indicators, moisture resistance, aging resistance, and expansion rate cannot meet the standards. Therefore, when a consumer purchases, it is necessary to check the product report and inspection report of the merchant. Long-term wear resistance. Because the geothermal floor should not be thick, the composite surface layer is generally 0.3-0.6 mm. The main surface of the paint wear resistance than traditional indicators.

TOF (Time of Flight) ranging sensor is a type of sensor that measures distance by calculating the time it takes for a light signal to travel from the sensor to the target object and back. It uses laser or infrared light to emit a signal and measures the time it takes for the signal to return to the sensor. By knowing the speed of light, the sensor can accurately calculate the distance between itself and the target object.
TOF ranging sensors are commonly used in various applications such as robotics, autonomous vehicles, industrial automation, and augmented reality. They provide accurate distance measurements and can be used for object detection, collision avoidance, gesture recognition, and mapping.
Compared to other distance measurement technologies like ultrasonic sensors or infrared proximity sensors, TOF ranging sensors offer several advantages. They provide higher accuracy, faster response times, and can work in various lighting conditions. They are also capable of measuring longer distances and can be used for both indoor and outdoor applications.
Overall, TOF ranging sensors are a versatile and reliable technology for measuring distances and are widely used in many industries for a range of applications.
