1. Pressing glue and coloring paint directly affect the environmental protection of the floor.
Wooden floor design, fresh home
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, such as the composite floor, the environmental performance of the glue used directly affects the environmental protection of the floor.
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.
Second, the wood moisture content affects the performance of the floor
Some home solid wood flooring has not been used for a year, and cracking has occurred. However, I usually pay attention to protection. How can this happen? The direct cause of cracking of wooden floors is the moisture content of 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.
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. Solid wood flooring should ensure the normal control of the moisture content of the wood, while the solid wood dough in the multi-layer parquet is the key, and the dimensional stability affects the performance of the floor. 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.
