Nowadays, the flooring industry can be described as a wide variety. In the face of a dazzling array of goods, the owners of the first renovation can not start, and the floor heating floor is popular in the market. In the face of the essential items for home decoration, we should choose What should I pay attention to? Let’s take a look at this issue with Real Xiaobian.
At present, the flooring on the market mainly includes laminate flooring, multi-layer solid wood flooring, solid wood flooring, bamboo flooring and PVC flooring. In recent years, high-grade cork flooring has appeared. So, what kind of flooring is most suitable for floor heating? ?
1. The floor heating is transmitted to the surface through the heat source of the ground, and the air is heated by the radiation process. Then only the concrete and the floor decoration layer that hinder the heat transfer, the thermal conductivity of the concrete is 0.8~1.4W/(m?k), and the thermal conductivity of the horizontal stripes of the wooden floor is 0.070~0.233W/(m?k) is a poor conductor. Then, in order to achieve the effect, the wooden floor must be reduced in thickness.
The purpose of ground heating is to meet the indoor design temperature. The design temperature of the ground required by the National Ground Radiant Heating Technical Regulations JGJ1402-2004 is 24.28 °C.
The floor thickness of 12 ~ 16mm is suitable for floor heating. If the design is special, it can only increase the water temperature of the floor heating pipe, which will reduce the service life of the floor heating system. If the temperature difference between the upper and lower surfaces of the floor is too thick, the telescopic inconsistency will deform the floor for a long time.
2. The ground temperature of the floor heating is about 30 °C. When the amount of formaldehyde released at 20 ° C is about 10 times that of 15 ° C, then it should be a large value at 30 ° C. The harm of formaldehyde to the human body is the common knowledge of everyone. Why is formaldehyde used in the floor? Because formaldehyde is the cheapest and most suitable for all kinds of gels and paints, the manufacturers only want to reduce costs. The current chemical technology has been able to produce formaldehyde-free products, but at a higher price. The national floor standard stipulates that the E1 level is ≤1.5mg/L, which is the rule in the ordinary floor. The floor heating floor should be formaldehyde-free to ensure the health of the consumer, but it is not impossible. Because there are also a small amount of formaldehyde in natural logs, there will be a small amount of formaldehyde, leather, and water in the new clothes, but their content is small and will not cause harm to the human body.
3. At present, the floor covering method in China is mainly suspended. This method is to lay a layer of floor mat on the ground and then lay the floor on it to solve the sound of floor and ground slamming. The suspension method will produce an air layer on the ground, and the heat transfer performance of the air is very poor, only 0.01919w. k/m, but the suspension method is significantly better than the keel installation, which is more closely connected to the ground than the keel installation.
4, the thermal expansion rate of solid wood flooring is about 1%, this value is in the case of solid wood floor moisture content of less than 15%. The higher the water content, the greater the shrinkage rate, so there is a large expansion joint at the wall when paving. The thermal expansion rate of the industry standard 5.2 is 0.3-0.4%. The expansion stress of the floor heating floor should be released inside. The floor heating special floor does not need to reserve expansion joints when paving.
5. The surface temperature of the floor heating is around 30 °C, which is a challenge for any wooden floor. Will it be deformed at this temperature? To achieve long-term deformation at this temperature, there must be a scientific theoretical basis. The interior of the floor should be well-balanced, so that it will not be deformed only when the texture of the wood is criss-crossed, and it has to be multi-layered and criss-crossed. Only multi-layer solid wood can meet this requirement.
6. The expansion and contraction of the floor paint is different from the expansion of the wood. The paint is small, the wood is large, and it will be more obvious under high temperature conditions until it cracks and falls off. The adhesion of the paint is critical, and the thicker the paint, the worse the adhesion will be.
Based on the above questions, the real floor heating floor should be:
1. The thickness of the special floor for floor heating is preferably 12 to 16 mm.
2, its products must be formaldehyde-free environmentally friendly products.
3. In order to achieve better heat transfer effect, the floor heating floor should ensure as little clearance as possible on the ground.
4, the size of the floor heating floor should not be too large, the smaller the size, the better the stability, and it is best to be a multi-layer solid wood product, this floor does not need to leave expansion joints when paving, its heat expansion Force to offset each other inside the floor.
5. The paint on the surface of the floor enters the interior of the wood by intrusion. It is wear-resistant and will not crack due to high temperature. This immersion technology was developed in Japan in the past two years and is also the experience gained through years of use. This technology has been widely applied to the field of floor heating floor.
The so-called floor heating floor of the market should be called a heat-resistant floor. It has a certain difference from the floor heating floor. It should be carefully purchased, not to listen to the business.
Summary: With the above analysis of the floor heating floor and the precautions when purchasing, I believe that even if the owner of the first renovation will have a lot of thoughts, then when you really buy, you will see more and compare more, I believe this will Less renovations, more renovations.
