In many types of household products, our usual point of view is: the more natural the raw materials, the higher the environmental performance. But in fact, any natural materials must be processed, and if the method used in the process 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 naturally indispensable. The first is to choose environmentally friendly products. In many types of household products, our usual point of view is: the more natural the raw materials, the higher the environmental performance. But in fact, any natural materials must be processed, and if the method used in the process is not environmentally friendly, it will also affect the environmental performance of the product.
Pressing glue and coloring paint directly affect the environmental protection of the floor
It is said that formaldehyde is the first killer of indoor pollution. Among all the materials used in the decoration, the highest amount of formaldehyde emission is undoubtedly all kinds of bonding glue. In the process of making the floor, especially the floor which needs to be glued to the floor substrate and the skin by the glue, the environmental performance of the glue used directly affects the environmental protection of the floor. In the parquet production plant of the living floor, we can see that all the parquets are made of environmentally friendly glue developed by the Finnish company. It is understood that this glue can guarantee the formaldehyde release of the pressed floor. The amount is within E1 grade, its curing speed is fast, the bonding strength is high, it can be cured at room temperature or high frequency. The rubber does not contain harmful components such as formaldehyde, phenol and heavy metals, and has a long storage period, which is suitable for the bonding of common tree species. High solid content is an important feature of environmentally-friendly and energy-saving adhesives. This feature can fully guarantee the firm pressing of the floor substrate and the skin, while ensuring that the formaldehyde emission is within the environmental standards.
In addition to the glue used for pressing, the paint used for floor sealing and coloring is another indicator of its environmental performance. When consumers buy the floor, they should ask whether the purchased floor is painted with environmentally friendly paint. Determine the environmental friendliness of the floor. For the edge-sealing paint, according to the person in charge of the floor factory of the living room, the chemical element benzene is one of the ingredients, and benzene is a substance harmful to the human body, but consumers do not have to worry about it because the benzene element volatilizes very quickly. Fast, in the process of floor sealing and post-processing, it will continue to evaporate, so it has almost no adverse effect on the health of consumers who buy the floor. For the workers who are working, the factory has to be specialized. Sealing exhaust gas treatment and discharge system to ensure the health of workers.
Wood moisture content affects floor performance
The solid wood floor of the house has not been used for a year, and cracking has occurred. However, I usually pay attention to protection. How can this happen? In the production plant of the living floor, we learned that the direct cause of cracking of the wooden floor is the moisture content of the wood. Usually, wood and its products will have a certain amount of water, and the percentage of the weight of the water in the wood and the weight of the wood after drying is the moisture content of the wood. In order to make the wood products better adapt to the climate and the living environment, in the production of wood products, the drying and curing of the wood will be carried out according to the moisture content standard of one place, so that the moisture content of the wood and the average moisture content of the atmosphere in the use area Consistent to ensure stable use of wood products.
Due to the difference in geographical location, the average moisture content in the atmosphere will vary. Therefore, the water content requirements of wood products vary from region to region. For example, the average moisture content of air in Beijing is 11.4%, while in the south, it is about 14%. According to the requirements of the product, it is between the positive and negative of the local average water content, Li Jiguang, deputy station director of the Wood Furniture Quality Supervision and Inspection Station. The water content directly affects the quality and use of wooden furniture, especially solid wood furniture. If the water content is low, the wood will absorb the moisture in the air, causing the wood product to expand and deform. When the water content is high, it will face the risk of cracking.
In general, wood products, especially solid wood furniture, preferably have a moisture content that is a little lower than the average moisture content of the local air, for example, one to two percentage points. For the floor decoration materials, the person in charge of the floor of the living room floor said that the solid wood floor should ensure the standardized control of the moisture content of the wood, and the solid wood dough in the multi-layer solid wood composite floor is the key, and the dimensional stability affects Floor performance. In the north, in order to prevent the phenomenon of floor cracking during the dry heating season, the wood veneer on the surface of the large brand parquet should be selected by professional quality inspectors, and the moisture content should be strictly controlled. Then make qualified multi-layer parquet slabs. Since the floor substrate is hot pressed after the decorative veneer is attached, a large internal stress is generated inside the slab, and the floor slab needs to be placed in a special temperature and humidity balance health room for about 20 days. In order to ensure the quality of the floor is more stable, effectively avoiding cracking and deformation during use.
