This winter, snow seems to fall in love with Chengdu. So far, Snow has visited this city for the seventh time, and its intensity has even surpassed that in 2008, and the temperature has hit the lowest record for the same period in 34 years. It is understood that the floors that can be used in conjunction with ground radiant heating systems in the floor market recently (referred to as "floor heating") are very popular among consumers.
Common wood flooring is divided into solid wood flooring, solid wood flooring and laminate flooring. So what kind of floor is suitable for floor heating? Floor heating floor is not a specific product. Floor heating system is a kind of heating system that uses heating floor to achieve heating. In the process of heating the floor heating system, the floor always maintains a high temperature. Under such circumstances, the ordinary floor is easily deformed. According to this working characteristics of floor heating, the floor heating floor should meet three conditions: First, it can adapt to the characteristics of repeated changes in the heating and cooling system of the floor heating system, with a small amount of deformation; second, it is conducive to heat conduction; and third, it is moisture-proof and waterproof.
Wood is a poor conductor, and the greater the thickness, the less conducive to heat conduction. At present, most floors on the market such as 12mm 18mm thick solid wood flooring, bamboo flooring, and ordinary solid wood laminate flooring with a thickness of more than 8mm are not suitable for floor heating systems, otherwise they will affect heat conduction. In the same environment, the deformation rate of solid wood flooring is the largest, followed by the strengthening of wood flooring, and the deformation of solid wood flooring is the smallest because of the horizontal and vertical staggering between each layer of the base material, the mutual containment, and the dense anti-deformation grooves on the back. The structure helps to decompose the stress generated by the heating surface.
At present, the country has not established relevant standards for floor heating, nor does it have special floor heating. In this regard, the expert's proposal is that solid wood composite, laminate flooring is suitable for floor heating, and solid wood flooring is used with caution.
After integrating various materials, the author discovered that in the process of purchasing floor heating, the following points should be grasped:
The thickness of 6.5 mm 8.5 mm is appropriate; the greater the thermal conductivity, the better the thermal conductivity of the general wood is between 0.17 0.34; the smaller the size, the better the smaller the size, the better the stability; the expansion rate is ≤2.5%. In general, the expansion The smaller the rate, the better the moisture resistance of the floor; the release of free formaldehyde ≤ 1.5 mg/L is as small as possible, and the E0 floor formaldehyde emission is ≤ 0.5 mg/L).
The obvious advantage of warm floor heating is a more comfortable way of heating. The room with a floor heating system has a gradual decrease in temperature from the bottom to the top with an increase in altitude. At the same time, the indoor surface temperature is uniform and the air quality is good. This temperature curve is just in line with the physiological needs of humans and can give people a comfortable feeling of cooling their feet. At the same time, warmth can promote foot blood circulation, thereby improving systemic blood circulation, promoting metabolism, and to a certain extent, can improve immunity. In addition, the "hot foot cold" environment can avoid drowsiness, is conducive to brain memory, improve learning and work efficiency. The traditional heating system or equipment that uses convection as the main heat transfer method, the temperature distribution condition it forms in the room is: the temperature at the top of the room is higher and the temperature at the bottom is lower. This temperature environment not only makes people feel uncomfortable, but also does not help the body.
The most critical market acceptance of floor heating flooring products will always be dazzling consumers, and there is no choice. In this regard, experts advise consumers that regardless of how businesses advertise, consumers must do a good job of acceptance.
Floor warming tests should be conducted after floor warming is completed. After the floor heating installation is completed, in addition to the routine acceptance, the most critical step is to warm up the floor. After the floor is laid or during the heating period after entering the winter, when the floor warming system is operated for the first time, the temperature should be raised slowly. When the base surface temperature reaches 25 degrees Celsius, this temperature should be maintained for 12 hours and 24 hours. Then, slowly increase the temperature at 1 degree Celsius per hour until it reaches the set room temperature of 14 degrees Celsius and 22 degrees Celsius. The surface temperature of wood floors should not exceed 28 degrees Celsius. In a short time, the limit temperature can not be higher than 32 degrees Celsius, the higher the temperature is, the greater the loss of thermal energy and the shorter the life of the thermal system. It is also prone to hidden troubles, and the floor is prone to scooping, twisting, bending and cracking.
After the floor pavement is completed, environmental acceptance should be done. There is a problem of release of formaldehyde in the laminate floor itself, and when it is used as a floor heating floor, the amount of formaldehyde released after heating may increase. Therefore, after paving the warm floor, it is necessary to do environmental protection acceptance to ensure that the release of free formaldehyde meets the standard requirements of the national standard of 1.5 mg/l. To ensure that the floor can meet the functional requirements of floor heating, procurement must be done in two ways: First, the environment should be tested before laying the floor to warm the floor, after the laying of the environmental protection acceptance; Second, the environmental protection indicators must be up to the floor heating accessories.
