(1) Moisture in the air (for example, Huang Meitian).
(2) The floor was not dried and the keel was reinforced with cement.
(3) Keel, wool floor is too wet.
(4) Use water-based glue.
(5) The damp environment on the first floor is not subjected to special moisture treatment.
(6) The sections where the stone floor and floor meet are not closed.
(7) Blisters (such as broken water pipes, backwater from balcony, etc.).
In addition, the product itself and improper construction can cause arching. For example, improper drying, insufficient health, too low water content, too shallow backgroove, insufficient clearance for expansion and contraction during construction, and too tight laying;
Tips for choosing floor tips
Home decoration is a whole concept, in which the floor is the carrier and stage of the entire home design. Whether the choice of floor design, color, and style can embody rich connotations is crucial to the overall beauty of the home. So, what should you pay attention to when choosing a floor?
The key to choose the floor is to choose the color and material
In the process of home design and decoration, the selection of floor colors and the choice of materials are very important. Since the floor is the stage of the entire home design, the floor has the largest area of ​​home life, so the color of the floor has become the background and foundation of the entire home design. In addition, the floor design should pay attention to the basic tone, this tone is the mix of colors, but also consider the color purity and brightness. In addition, when designing flooring, it is important to look at the material of the floor. The material of the floor and the material of the furniture and the material of the wall should be well combined. This can give people a sense of change and a sense of depth.
Pay attention to overall harmonious local contrast
The overall decoration style and concept of the home is the primary factor in determining the color of the floor. Dark-colored floor has a strong appeal and expressiveness, distinctive personality characteristics, light-colored floor style is simple, fresh and elegant. In recent years, the appearance of some seemingly awkward wooden floors, such as tree festivals, insect eyes, decayed, cracked texture floors, is a manifestation of people’s emphasis on the concept of nature and returning to nature.
Second, pay attention to the matching of floor and furniture. The color of the floor should set off the color of the furniture and be mainly calm and soft. Because the floor decoration is a permanent decoration, under normal circumstances, it will not be replaced frequently, so choose neutral colors. From the hue, the light-colored furniture can be arbitrarily combined with the light-colored floor, but the dark-colored furniture and the dark-colored floor should be carefully used to avoid the "black" depressing scene.
The room lighting conditions also limit the choice of floor colors. It is not necessary to say that a room with good lighting is free to choose. For a room with a low floor and insufficient lighting, you should pay attention to the floor materials with higher brightness and suitable colors, and avoid using darker materials as much as possible.
For example, the living room was the most public space, but also the main place for daily activities and receive guests, so should adopt high transparency, soft colors, to create a clear, harmonious atmosphere.
The hue of the study strives for elegance. The study is a static working space for people to read, write and learn. People demand calmness, attention and peace. Indoor tone required to elegant, dignified, harmonious tones, so choose gray, brown and gray, brown green, light blue, light green and so is appropriate, choose a dark ground, brown and other colors of the lining, while a small amount of available Crafts Embellishment to increase the contrast of the interior color, can consider the compound floor with the advantage of color.
Color affects people's visual effects, warm colors are expanded colors, and cold colors are shrink colors. Therefore, the floor of the room with a small area should be chosen from the cool colors of the dark colors, giving people the feeling of expanding the area. If you use a brightly colored warm floor, it will make the space more narrow and add to the sense of depression.
Comparison between the IKEA model, you can find a very interesting phenomenon, IKEA basically chosen laminate flooring, laminate flooring has its own advantages in color, relatively simple in color, more harmonious, but by no means simple, simple, light and shadow through The changes show the texture created by the laminate flooring.
Water content of solid wood flooring
There are three forms of water contained in wood. One is the water present in the cell space and intercellular space, that is, the water present in the capillary tube, which is called free water. The second is the water absorbed by the cell wall, called adsorbed water. The third type is the water that makes up the cell tissue called chemical water.
When moist wood moisture evaporates, the first thing that is lost is free water. When the free water evaporates and the moisture content of the adsorbed water is still saturated, it is called the fiber saturation point moisture content.
Fiber saturation point is a turning point in the performance of wood. Above the fiber saturation point, the strength of wood is constant and does not change with the change of moisture content. At the same time, there is no volume change in the wood. When the moisture content falls below the fiber saturation point, that is, when the adsorbed water in the cell wall begins to evaporate, the strength increases with the decrease in moisture content, and the phenomena of bloating and shrinkage also appear clearly. The moisture content of different wood fiber saturation points is between 22% and 33%.
The humidity and temperature in various regions of the natural world are relatively stable in different seasons. Wood is in such a relative temperature and humidity environment for a long time, and its moisture content will reach a relatively constant. The moisture content at this time is called the equilibrium moisture content (for example, the annual equilibrium moisture content in Shanghai is 14.6%).
The equilibrium moisture content of wood varies with the temperature and humidity of the environment in which they are located. When the equilibrium water content and the ambient humidity have differences, they tend to approach the environment. This produces the phenomenon of wood swelling and shrinkage, which is a unique physical phenomenon of wood.
Wood is also an anisotropic body. The moisture content of wood in actual use is below the fiber saturation point, so the gain and loss of water is mainly the adsorbed water of cell walls. The vast majority of wood cells grow longitudinally, and their expansion and contraction are perpendicular to the cell wall direction. As a floor, we can find that there is generally no expansion or contraction in its longitudinal direction, and the shrinkage rate in the width direction is generally 3% to 6% (refers to the change of wood moisture content below the moisture content of the fiber saturation point).
From this, it can be seen that the control of the floor's moisture content in the floor is not only important in the production of the floor, and the floor is more important in the laying of the floor, so that the floor will not be deformed by moisture.
