among many types of household products, our common view is that the more natural the raw materials, the higher the environmental protection performance. But in fact, any pure natural material must be processed, and if the way used in the processing is not environmentally friendly, it will also affect the environmental performance of the product

as people pay more attention to the concept of environmental protection, most consumers have begun to consume for environmental protection. In the process of home decoration, the requirements for environmental protection are also natural. The first thing is to choose environmentally friendly products. Among many types of household products, our common view is that the more natural the raw materials, the higher the environmental protection performance. But in fact, any pure natural material must be processed, and if the way used in the processing is not environmentally friendly, it will also affect the environmental performance of the product

adhesive plaster and colored paint directly affect the environmental protection of the floor

it is said that formaldehyde is the first killer of indoor pollution. Among all materials used in decoration, there is no doubt that all kinds of adhesives have the highest formaldehyde emission. In the manufacturing process of the floor, especially the floor that needs to be glued with glue to bond the floor substrate and the skin, such as the solid wood composite floor, the environmental protection performance of the glue directly affects the environmental protection of the floor. In the production plant of solid wood composite flooring for living floors, we can see that all solid wood composite flooring uses an environmental friendly adhesive developed by Finland TAIR company. It is understood that this adhesive can ensure that the formaldehyde emission of the pressed floor is within E1 level. It has fast curing speed and high bonding strength. It can be cured at room temperature or high frequency. The adhesive does not contain harmful ingredients such as formaldehyde, phenol and heavy metals, and has a long storage cycle, Suitable for gluing common tree species. High solid content is an important characteristic of environmental protection and energy-saving adhesive, which can fully ensure the firm adhesion of floor substrate and skin, and ensure that the release of formaldehyde is within the environmental protection standard

in addition to the adhesive used for pressing, the paint used for floor edge banding and coloring is another indicator of its environmental protection performance. When consumers buy floors, they should ask whether the purchased floors are colored with environmental protection paint to determine the degree of environmental protection of the floors. As for the edge banding paint, according to the person in charge of the floor factory of lifejia, the chemical element benzene is one of the ingredients, and benzene is a substance harmful to human body, but consumers don't have to worry about it, because the volatile speed of benzene is very fast, and it will continue to evaporate in the process of floor edge banding and post-treatment, so it has almost no adverse impact on the health of consumers who buy floors, For the workers who are working, the factory also needs a special edge sealing waste gas treatment and emission system to ensure the health of workers

the moisture content of wood affects the service performance of the floor

some readers have reported that their solid wood floor has not been used for enough a year, and cracking has occurred. However, they usually pay attention to protection. How can this phenomenon occur? In the production plant of living floor, we learned that the direct cause of wood floor cracking is the moisture content of wood. Usually, wood and its products will have a certain amount of moisture, and the percentage of the weight of moisture in wood and the weight of completely dried wood is the moisture content of wood. In order to make the wood products better adapt to the climate and living environment, when making wood products, the wood will be dried and cured according to the local moisture content standard, so that the moisture content of the wood is consistent with the average moisture content of the atmosphere in the use area, so as to ensure the stable use performance of the wood products

due to different geographical locations, the average moisture content in the atmosphere will vary. Therefore, different regions have different requirements for the moisture content of wood products. For example, the average moisture content of the air in Beijing is 11.4%, while that in southern China is about 14%. The specific requirements for products are between plus and minus 1 of the local average moisture content, said Li Jiguang, deputy head of the wood furniture quality supervision and inspection station. Moisture content directly affects the quality and use of wooden furniture, especially solid wood furniture. If the moisture content is low, wood will absorb moisture in the air, causing the expansion and deformation of wood products; If the moisture content is high, it will face the risk of cracking

generally speaking, the moisture content of wood products, especially solid wood furniture, is better to be a little lower than the average moisture content of the local air, for example, one to two percentage points. As for the floor decoration materials, the person in charge of the factory of living home flooring said that the solid wood flooring should ensure the standardized control of the moisture content of wood, and the solid wood veneer is the key in the multi-layer solid wood composite floor, and its dimensional stability affects the performance of the floor. In the north, in order to prevent floor cracking and other phenomena in the dry heating season, the wood seed veneers on the surface of large brand solid wood composite flooring should be selected piece by piece by professional quality inspectors, and their moisture content should be strictly controlled. Then make qualified multi-layer solid wood composite floor slabs. Because the floor base material is pasted with decorative veneer and then hot pressed, the slab has a large internal stress. Such a floor slab also needs to be kept in a balanced curing barn with special temperature and humidity for about 20 days, so as to ensure that the quality of the floor is more stable and effectively avoid cracking and deformation in the process of use
