Solid wood flooring with not enough a year, occurs cracking phenomenon, but usually also very focused on protecting, how is there such a phenomenon? In the living home floor production facility we learned that a direct reason for cracking wood flooring is the moisture content of the wood. Typically, the timber and its products will have a certain amount of water, and the weight of water contained in the wood and wood percentage by weight of oven-dry after that moisture content of wood. In order to better adapt to climate wood products and home environment, in the production of wood products, wood drying are carried out according to health and to a moisture content of standards, so that the average moisture content of the atmosphere and the moisture content of wood use area consistent, to ensure stable performance of wood products.
Because there will be differences in different atmospheric average moisture content location, therefore, different regions of the moisture content of wood products for different requirements, such as the average moisture content of the air in Beijing is 11.4%, while in the south, compared with about 14% , specific to the requirements of the product on the local average moisture content of between plus or minus 1, wood furniture quality supervision, inspection Zhanfuzhanchang Li Jiguang representation. Moisture content directly affects the quality of wooden furniture and especially the use of solid wood furniture, low moisture content of the wood will absorb moisture from the air, causing swelling deformation of wood products; and high moisture content, it will face the danger of cracking.
Generally, wood products, especially solid wood furniture, its moisture content is preferably low moisture content than the average local air a little, for example, one or two percentage points. As for the surface decoration materials, living at home floor of the factory manager said that solid wood flooring to ensure good moisture content of timber standardization control, and multi-layer parquet in wood dough is the key to the stability of its size on the impact of the performance of the floor. In the north, in order to prevent cracking and other phenomena in the dry floor heating season, the big brands of wood veneer parquet surface quality professional staff should all piece selection, strict control of its water content. And then made a qualified wood flooring slabs. Since the decorative veneer floor substrate in paste then after pressing, the slab has produced a larger internal stress, such floor slab also need to stand in balance health positions in special temperature and humidity regimen 20 days , thus ensuring the quality of the floor is more stable and effective process to avoid cracking and deformation.
