Fake and shoddy laminate flooring usually uses cheap decorative paper made in China. The pattern of this decorative paper is vague, and the biggest defect is that it is generally not resistant to ultraviolet rays and will fade after sunlight. 2. Cheap decorative paper made in China is usually chosen. This kind of decorative paper has a vague pattern, and the biggest defect is that it is generally not resistant to ultraviolet rays and will fade after sunlight. Laminated flooring originated in Europe, which is a new type of flooring based on wood-based panels. Generally, it can be divided into two categories: reinforced flooring based on medium and high density fiberboard and reinforced flooring based on wood shavings. Widely used in family rooms, public places, conference halls, dance halls, hotels and other places.

Focusing on the current floor market, fake and shoddy flooring presents the following five characteristics.
1. Generally, wear-resistant paper with alumina content of about 20g/_ is used, or wear-resistant paper is not needed. Low-density board (rarely used in medium-density board), the wear-resistant revolution is generally between 100-3000. The corners will wear out in a year or two at most.
2. Cheap decorative paper made in China is usually chosen. This kind of decorative paper has a vague pattern, and the biggest defect is that it is generally not resistant to ultraviolet rays and will fade after sunlight. This is also why some consumers have reported that after three or four months of floor installation, the places near balconies and windows become discolored.

3. Poor base material, medium density board or particleboard, unstable quality index, and serious formaldehyde exceeding the standard.
According to professionals, the service life of the floor heating system mainly refers to the service life of the buried pipeline, because the above-ground part can be replaced, and the choice of the floor heating pipeline is the key to the service life. At present, the service life of qualified pipes used in floor heating system can reach about 50 years. Some people in the industry oppose this view. If residents privately change the traditional wall-mounted heating in their homes to floor heating, they must be careful not to buy qualified pipes, but also find installation units with construction qualifications.
Strengthen the floor bit by bit.
Floor heating has both advantages and disadvantages. Many times, it is precisely because of the concealment of floor heating that once there is a problem in the later stage, the maintenance cost is usually high. Because the pipeline embedded in floor heating does not belong to the maintenance scope of heating company, in addition to the cost of replacing pipe fittings and labor costs, it also involves the cost of removing floors, tiles and ground decoration.
The rise of floor heating is not long, and most people see its advantages, but with the increase of service life, it will inevitably involve maintenance. In fact, whenever the heating pipeline of water circulation is used for a period of time, it involves the problem of pipeline cleaning. The floor heating link is often not reminded by residents that the industry engaged in floor heating cleaning has not yet formed a scale, and cleaning has become an "open space" that no one cares about. The use and maintenance of floor heating system need further attention and solution.

Pay attention to the age of the old community.
Many readers have this question. When the heating is used for several years, the pipe fittings will need to be replaced because of their service life.
According to the relevant regulations of national boiler water use, the earliest shelf life of pipe fittings should be more than 15 years, while in recent years, the shelf life of pipe fittings should be more than 25 years, so most owners don't have to worry about water leakage caused by pipe fittings aging. And some old community owners who have used cast iron valves for more than 10 years and have never replaced them need to pay attention to the shelf life.
Because the floor heating is installed on the ground, even if the water leaks when testing the water, unless it causes great damage, such as obvious situations such as the floor being soaked, the owner generally cannot detect it. Generally speaking, if the initial installation of floor heating is qualified and there is no hole in the ground, the design life of floor heating is 50 years. The owner has nothing to pay special attention to, just remember to open the valve before heating.
The most important thing for the owner is to pay attention to the notice of testing water in the community and stay at home to observe whether there are special circumstances when testing water.
Use floor heating slowly for the first time.
If the circulatory system was installed only this summer, this is the first time to use it. Is there anything to pay attention to? "For such owners, the first use of floor heating should pay attention to slow heating. Because cement and other floors can't guarantee that they contain water vapor, in order to avoid floor deformation caused by excessive moisture after heating, the heating of floor heating should be controlled moderately. The water temperature can be raised by 5℃ every two days to gradually dry the ground until it reaches the design water supply temperature. After that, don't bother too much, just do it in one step. "

Filters should be cleaned regularly.
There are suggestions on the internet that the filter should be cleaned regularly when using floor heating. Is this statement correct? How often should I clean it?
Floor heating can be divided into two ways: central heating, household metering and self-provided small boiler heating. If it is the owner of central heating, the hot water is provided by outdoor heating station or residential boiler room, and there will be some impurities or rust in the hot water. Over time, these rust will block the pipeline, thus affecting the indoor heating temperature. If the owner feels that the temperature has been affected to some extent, he can contact the property or the floor heating manufacturer for treatment.
Generally speaking, there is a filter screen when entering the house, which needs to be taken down and cleaned regularly.
If it is your own boiler, you don't have to worry about this problem.
Floor heating 18℃ is the most suitable.
If floor heating is used, what is the most suitable temperature setting? If it is the floor heating of the collective heating in the community, the temperature cannot be controlled. Generally speaking, the water temperature is around 40℃. If central heating is changed to floor heating, because the hot water temperature in the residential area can't be controlled, a backwater center will generally be installed during installation to adjust the inlet water temperature. The actual temperature given by radiation heat dissipation is higher than the actual temperature, which is generally set to 18℃ because the actual temperature is about 20℃. If it is a radiator, the temperature needs to reach 20℃, and people will feel comfortable.

3. The base material is poor, using medium and low density board or particleboard, the quality index is unstable, and formaldehyde seriously exceeds the standard.
4. The machining accuracy is poor, and it is often claimed that it is imported large plates and slotted at home.
5. Rough packaging, poor printing quality of promotional brochures, patchwork of contents, selling one set of advertising language after another, and often stealing the contents of big companies' brochures.

The "secret recipe" for purchasing high-quality laminate flooring
Buy laminate flooring, first look at the surface: the surface material is mainly melamine or alumina, which has superior wear resistance. The thickness of the surface layer is only 1 mm, and the thickness can reach more than 5 mm. You should not only look at the promotional materials of the merchants, but also understand the actual situation of the products. The promotional materials of many merchants indicate that the wear speed is "15000 rpm" and "18000 rpm". Except for a few cases, the products sold normally generally can't reach this speed. Of course, the thicker the same material, the more wear-resistant. The wear resistance is based on "rotation", and the wear resistance can be turned to 4500 rotation, which can be used in bedrooms and has a service life of about five years; 1000 rpm can be used in family living rooms and restaurants, with a service life of about ten years; 1500 rpm is suitable for public places. Secondly, look at the bottom layer: the main function of the bottom layer is to resist the deformation of the composite floor in dry, wet, cold and hot changes. If geothermal heating is used, it is best to use composite floor.

If you don't buy the "three noes" products, you should carefully buy the "all-foreign-language packaging" products, and the regular products should have Chinese logos and related instructions that conform to domestic laws and regulations. High-quality imported laminate flooring generally has the international environmental protection logo Der Blaue Engel pattern, and the authoritative certification body of domestic environmental protection standards is CCEL-China Environmental Protection Logo Product Certification Committee, and the domestic environmental protection logo is the seven-ring pattern. You should buy some products from well-known enterprises. Most of these enterprises have large production scale, advanced production equipment, certain detection means, guaranteed product quality, good after-sales service and easy solution to product quality problems. You can't just buy cheap ones. The comprehensive price of raw material cost, production cost, sales cost and normal profit of merchants of qualified products should be around 60 yuan /m2. Unless there is promotion, the normal price should not be lower than this price. And some cheap products are likely to use unqualified raw materials.

Environmental protection index refers to the formaldehyde emission of strengthened floor. Formaldehyde is an indispensable substance and the most important pollutant in the production of laminate flooring. At present, the domestic formaldehyde emission standard of laminate flooring is 20mg/ 100g, and the international standard is 8mg/ 100g. The less formaldehyde content, the less pollution; Because the production process of laminate flooring contains a large number of high-strength PVC aggregates and high-strength adhesives, its compressive strength and tensile strength can generally meet the use requirements.
The water resistance index of laminated wood flooring is evaluated by the water thickness expansion rate. The lower the water thickness expansion rate, the better the moisture resistance and water resistance. Because the formaldehyde emission of laminate flooring is stipulated in Chinese national standards, it does not exceed 1.5MG/L, which is in line with national standards. Wear-resistant revolutions The wear-resistant revolutions of reinforced floors for home use should be _ 6,000, and those for public places should be _ 1 0,000, otherwise it may be damaged to varying degrees after using 1-3 years. Choosing your favorite color within an acceptable price range is the ultimate goal. Pay attention to whether the pattern is defective when inspecting the goods.
