At present, many commercial houses have chosen geothermal heating methods. Compared with traditional heating, the temperature near the ground is higher than the temperature of the ceiling, which is in line with the comfort of the human body. Moreover, geothermal heating has eliminated heating pipes and radiators in the room, which is more conducive to the layout and beauty of the living room. Therefore, this method has been recognized and accepted by more and more people. But it also made a lot of consumers guilty of the decoration: a variety of floors in the building materials market, it is dazzling, coupled with the sales staff of each business, said that their floor is 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?
First, the misleading of the geothermal floor The Ministry of Construction had proposed that we must vigorously promote the use of ground low-temperature radiant heating systems. 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.
Someone once investigated in a medium-sized building material home improvement market. 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 this can't be used in heating systems, and 25% can be used for floor heating, but the effect is not ideal. Only 20% of it is dedicated floor heating. . Therefore, to remind consumers to pay special attention to certain misleading claims: If thicker wood flooring "thicker foot feeling is better," "thicker and more thermal insulation," the back of a foam pad, aluminum foil, printed on the packing box "conservatory "Special" is the geothermal floor and so on. As everyone knows, these arguments are unreasonable; they only affect the cooling of the ground.
Second, how to buy geothermal floor due to the special nature of geothermal heating, the floor is very strict requirements, therefore, in addition to the geothermal floor to meet the conventional quality indicators, but also to meet the following four major requirements:
1, thermal conductivity is better - should not be thin thick.
Since the ground heat is transferred to the surface through the floor, there is bound to be heat loss, and ideal flooring materials 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." Geothermal floor thickness is generally 0.3-0.6 mm.
2, the dimensional stability is better - not small should be large.
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 raised, and the wooden floor is bound to undergo double changes of “temperature†and “humidityâ€. Xinhao Plastic Flooring adopts advanced glass fiber layer, which has good dimensional stability and will not be affected by temperature and humidity. Therefore, geothermal floors must be purchased with good stability.
3, moisture and heat resistance is better - suitable for environmental protection plastic.
Because the geothermal floor must withstand high temperature heating for a long time, it is required that the decorative layer of the product be stable in performance, and that under the condition of long-time high temperature, there will be no fading and rough light. The floor should use adhesives. The adhesives must meet the three major indicators 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, pay attention to whether the adhesive is environmentally friendly.
4, formaldehyde emission can not exceed the standard.
Geothermal floors require that the amount of formaldehyde released does not exceed the limit in the case of prolonged heating. When consumers choose geothermal floor, we must choose the floor with low formaldehyde content as possible, because the higher the temperature, the greater the amount of formaldehyde released, in the relatively closed residential room, together with the release of formaldehyde caused by other indoor articles, indoor formaldehyde has It may exceed the standard and cause harm to the human body. Therefore, when a consumer purchases, it is necessary to check the product report and inspection report of the merchant.
