The most common causes of wood floor cracking are the moisture content of the floor and the dry humidity of the environment. For example, the moisture content of the wood floor is % and the local average moisture content is %. In order to balance the moisture content of the floor and the moisture content in the air, the dry air absorbs moisture from the wood floor, and the wood floor cracks in this processLaminate flooring is suitable for meeting rooms, etc. it can also be used for the ground decoration of medium and high-grade hotels high-definition cleanliness laboratories, restaurants and civil houses.Although laminate floor has moisture-proof layer, it should not be used in wet places such as bathroom and toilet.The first is the type of raw material.When purchasing solid wood multi-layer wood floor, you should pay attention to whether the floor is the same material and whether the surface has defects such as crack, rot, skin clip, dead joint, moth eaten, moldy and so on.The general high-quality solid wood multi-layer wood floor shall have clear lines and bright colors on the surface.Santarem,SPC floor does not use strong glue in the production process, so there is no indoor formaldehyde, benzene and other harmful substances. The real indoor formaldehyde low-carbon environmental protection floor has no damage to the body.The commonly used floor is generally mm thick, the material will not be very expensive, the foot feels comfortable, the service life is relatively long, and it will not be easily damaged.Consumers who use wood flooring in home decoration know that if it is not maintained properly in the process of normal use there will be a series of problems with wood flooring.Floor cracking is a common method.Today, we will discuss why the wood floor cracks.Kakogawa,High concentration formaldehyde is a genotoxic chemical.In animal experiments, high concentration inhalation in the laboratory can cause nasopharyngeal tumors.Defects: poor wear resistance, no fire prevention, no corrosion resistance, very easy to regain moisture, deformation, thermal deformation, folding, etc., and must be polished and waxed on time, which is difficult for medical treatment.Physical and mental health floor is the floor produced according to the production and manufacturing product quality standards and installation and application testing standards (double specifications), which is not easy to cause harmful substances and ensure the health and safety of residential gas.

For laminate flooring,SantaremHow about SPC stone plastic floor, the main standard of floor environmental protection is formaldehyde emission.In terms of the limitation of formaldehyde emission standards, the environmental protection of the flooring industry has experienced three technological revolutions: E, E and FCF.At an earlier stage, the formaldehyde emission standard of wood-based panel is E level (formaldehyde emission ≤ mg / g), and its formaldehyde emission limit is very loose. Even for products meeting this standard, the formaldehyde content may exceed more than three times that of E level wood-based panel, seriously endangering human health, so it must not be used for home decoration.Therefore, there was the first environmental protection revolution. In this environmental protection revolution, the flooring industry implemented the E level environmental protection standard, that is, there are still a lot of free formaldehyde left in the floor.The flooring industry has started the second environmental protection revolution and launched E environmental protection standard, which has reduced the formaldehyde emission of the floor to . ‡ / L.The best way to identify whether the floor is environmentally friendly is to pry the floor from the lock with a screwdriver and hammer,SantaremHow thick is the floor leather,SantaremClassification of floors, so that the floor substrate is exposed in a large area, and then smell it with your nose. A good floor should have a wood smell, but a bad one has a strong pungent smell!Look at the color.The standard laminate floor surface should contain aluminum oxide wear-resistant paper. It has g, g, g, and even lower. It is directly sprayed with aluminum oxide on the decorative paper. The state stipulates that the surface wear-resistant revolution of the laminate floor for indoor use should be more than revolutions. Only the floor with g wear-resistant paper can meet the requirements. The wear-resistant revolution of g wear-resistant paperThe number of revolutions can reach - or even lower than g. It is good if the number of revolutions directly sprayed with aluminum oxide can reach -. For those with low wear-resistant revolutions, the material cost is relatively low; because of its low wear-resistant degree, the tool cost during processing is also low. On the contrary, the cost is much higher if the number of wear-resistant revolutions is high.Quality management,Fourth, wear resistance means that it is not easy to scratch with artifact.In today&#;s building materials industry, there are many incidents of profiteering and even damaging the interests of consumers. The bad atmosphere has led to the reduction of consumer trust.The price is in a state of confusion, and consumers are confused. They don&#;t know whether their pay is worth it. Therefore, they all want to know that there is a relatively transparent price.From to , Chinese traditional pure solid wood flooring and new solid wood flooring, which means three-layer and double-layer solid wood, have been surging in an undercurrent.In recent years, the upgrading of solid wood flooring category caused by new solid wood will become an important driving force to promote the consumption boom of home decorative flooring.The world financial storm has an impact on China&#;s wood flooring industry chain, but it is not rampant only lack of confidence in the market.The operation track of the development of market economy has been advancing in the cycle system of wave soldering and wave trough. The flooring industry is depressed and it is not easy to hold it for a long time. China has a strong foreign demand market, and the demand of China&#;s home building materials market is still very large.

SPC floor has special anti-skid property. The more it meets water, the more astringent it is. Even if you wear running shoes with nails, you won&#;t leave scratches on the floor.Quality risk,Well known brands: LG and Hanhua flooring in Korea, Armstrong flooring in the United States, Jiefu and Tejia flooring in France, fulbo flooring in Sweden, longxilu, tahilong, Dongli flooring in Japan, and domestic bonier flooring.For the pursuit of cost performance, choose Korean brands, Japanese brands for the pursuit of quality, European and American brands for the pursuit of brand effect, and domestic brands for low prices.Convenient installation and operation: the installation of solid wood composite floor is the same as that of laminate floor. It does not strike the ground keel. It only needs the ground leveling, and can also improve the building height.Defects: small blisters can not be repaired after damage and the upper foot is poor.Santarem,The wear resistance of laminate floor mainly depends on the content of aluminum oxide in the surface layer, and a certain number of wear-resistant revolutions corresponds to a certain content of aluminum oxide.For household floors, the number of wear-resistant revolutions is usually more than revolutions, while in public places, it is usually more than revolutions. You can buy it on demand.Direct contact with formaldehyde can cause skin allergy, pigment spots and atrophy. Inhalation of high concentration formaldehyde can cause chronic bronchitis.The surface texture of solid wood floor is clear and natural, and there is no obvious color difference on both sides.Medium and low grade solid wood floors indicate that cracks may occur.If the crack is not a problem between textures
