Misunderstanding of a European standard E1 is equal to the national standard E1
The European E1 standard European standard EN13329 uses a perforated extraction method.
Perforation extraction method: The tested laminate flooring is 10g absolute plate, which has been chemically/physically extracted;
The content of E1 ≤ 9mg/100g was directly measured.
National E1 Standard At present, the formaldehyde index of China's laminate flooring is GB18580-2001.
The E1 indicator uses a desiccator method, and the amount of formaldehyde released is ≤1.5 mg/L;
E0 indicator formaldehyde emission ≤ 0.5mg/L;
Substrates that meet the European E1 standard for perforation extraction can be used directly in the room even without facings; indoor
Misunderstanding two floor thicker more thermal insulation
Wood is a poor conductor, usually the thermal conductivity of wood material is between 0.17-0.34, while water is 0.5. If the floor thickness is too thick, it is not conducive to the conduction of heat through the floor to the board surface, which is consumed in the conduction process. And because the floor temperature difference between the upper and lower, it will inevitably lead to great deformation of the floor, "heat expansion and contraction" "swelling shrinkage" will cause the floor scoop, twist, bend, crack, dimensional stability can not be guaranteed.
Misunderstanding three floors thicker and more comfortable
Popular saying: Feeling better
The installation of solid wood floor keels only results in a more solid wood floor feel.
When the floor is not suspended by the keel installation method, the floor is in close contact with the ground, and there is no relationship between the thickness and the comfort of the human body; the so-called feeling of the foot is completely psychologically suggestive;
Misunderstanding four belt aluminum floor mat is dedicated for geothermal floor
In the geothermal environment, the heat transfer is mainly radiation, followed by convection, and finally conduction.
If the floor is covered with aluminum foil, reverse radiation will be formed. With the same surface temperature at the same time, the foam pad with aluminum film has a large thermal resistance, while the ordinary foam pad has a small thermal resistance. Obviously, the ordinary bubble
The pad has a better thermal conductivity than a foam pad with an aluminum membrane and is more conducive to heat transfer from the floor to the room.
Misunderstanding 5 does not pay attention to the baseboard and accessories selection
Baseboard to cover and protect the floor and wall joints, and the role of a fixed floor; should be installed with the floor, no post-market floor hidden dangers
Consideration should be given to the environmental protection of skirting boards and other accessories;
Recommendation: special cork floor mats can be used for laying; common foam floor mats have low thermal conductivity and are prone to harmful gases when exposed to high temperatures for long periods of time.
Misunderstanding 6 does not attach importance to the treatment of the ground environment
The ground must be level within a radius of two meters, and the height difference must not exceed 3mm.
The ground must be completely dry;
Before laying floors in winter, a geothermal heating test must be conducted with a water inlet temperature of at least 50°C to ensure that the heating system is operating properly.
And to keep warm for more than 24 hours to make the ground dry, to ensure that the moisture content meets standards.
Misunderstanding seven laminate flooring is also used wax / oil maintenance
The laminate flooring does not require any waxing and oiling maintenance. It only needs daily cleaning.
Floor maintenance refers only to solid wood flooring
Misunderstanding #8 does not attach importance to humidity regulation after installation
After the installation of the floor, the indoor humidity must be maintained between 40-60 degrees;
This is also the most suitable humidity for the human body;
The climate in Northeast China is dry, and geothermal heating is used in winter. The floor is exposed to high temperatures for a long time and it is easy to crack. It is necessary to humidify the room so as to avoid cracking of the floor.

The led solar flood light adopts aluminum alloy shell, which is light and practical. A point light source that can illuminate evenly in all directions, its illumination range can be adjusted arbitrarily, and it is represented as a regular octahedron in the scene.
Led solar flood lights are the most widely used light sources in rendering production, and standard floodlights are used to illuminate the entire scene. Multiple floodlights can be applied to the scene to produce better results. Floodlights are the most widely used light sources in renderings. Multiple floodlights can be used to coordinate in the scene to produce better effects. It illuminates an object uniformly from a specific point in all directions, and it is best to use it as an analogy to light bulbs and candles. Outdoor solar flood light is energy-saving, environmentally friendly and durable.
