Why does solid wood flooring have color difference?

Chromatic aberration usually refers to the color difference between two or more adjacent items, in the early days people pursued perfection without chromatic aberration, and over time, contemporary people's pursuit is more natural and casual beauty. Sports wood flooring materials installed on the stages of various stadiums and theaters are often accompanied by color aberration. How to look at the color difference of sports wood flooring:

1. Natural phenomena.

The color difference of sports wood flooring is a normal natural phenomenon. For example, the natural wood color is different due to the different growth environment of solid wood species. In addition, even the same log has different colors in different growth parts.

For example, the core material of the log and the outer material of the log, the color of the lower and upper parts of the log are also different.

2. How to solve it.

Although the color difference of sports wood flooring is a normal natural phenomenon. However, many stadium builders, especially stadium operators, do not see it that way. Customers always want sports wood floors to have no color differences, or as little color differences as possible.

We can understand the principle of wood color difference from the facet of wood. In the process of natural growth, affected by climate change and differences in soil conditions, different parts of the same wood are naturally formed in different colors and textures, so it is normal to have a slight color difference during installation, which is the manifestation of the natural charm of natural wood, and the color difference is the contact point that gives you inspiration and is the embodiment of natural aesthetics.

The reason why solid wood flooring can be deformed is because of the moisture-regulating properties of wood. Wood will change with the humidity of the environment, can absorb or discharge water, when wet, absorb moisture, will make the wood floor expand, such as the environment is too wet, resulting in the floor bulge or curl, when dry, discharge wood moisture, will make the wood floor shrink, if the environment is too dry, the splicing joint of the wood floor will be larger. Of course, it is normal for many rooms to have no gaps or slight curls in the rainy season, and they are very smooth or have gaps in the dry season.

And the key to the quality of wood flooring: wood drying. The purpose of drying is to dry and process the excessive moisture content of the wood itself to a balance moisture content that is compatible with the air temperature and humidity of the area where it is used.

Wood drying is the key to causing shrinkage and swelling as well as cracking of wood floors. In Guangzhou, the annual equilibrium moisture content of wood is about 15%, if the use of European and American standard dry materials (moisture content of 8-10%), the wood will inevitably swell and deform due to water absorption; The wooden flooring with a moisture content of 13% is used in Lhasa, Tibet, which has an annual equilibrium moisture content of 8%, and the opposite will shrink. Therefore, the drying of wood is based on the regional wood equilibrium moisture content.

Due to the vast territory of China and the large climate differences between regions, the production must be adapted to local conditions to ensure the quality of wood flooring.

Logs must have color differences, like the yang and shade sides of a tree, the core and the sapwood, the age of the tree is different, not the same tree, all have color differences. This is an inevitable phenomenon of natural logs. I hope my answer can help you.

Royalstar solid wood flooring is made of pure solid wood, because the natural color and texture of wood will have different degrees of color difference.

"Chromatic aberration" is explained in the sea of words as: the difference between two colors. Color consists of three characteristics: hue, saturation and brightness, and chromatic aberration is the comprehensive difference between these three. When consumers buy flooring, they often find that there is a difference in the color of the floor, which is commonly known as floor color difference.

In the process of production and processing, solid wood flooring is composed of one kind of wood from bottom to surface, and tree production is affected by sunlight to cause the color of the heartwood and the trunk to be different, so the color difference of solid wood floor is inevitable.

What is the reason for the color difference of the floor?

1) Natural factors: In the process of natural growth, trees are affected by climate change and differences in soil conditions, and different colors and textures of different parts of the same wood are naturally formed. Heartwood is usually dark in color and is located inside the cross-section of the trunk, the heartwood is gradually transformed by the sapwood, which is located on the outside of the trunk and is usually light in color.

2) Installation factors: because there is a color difference in the floor itself, if the installation master does not observe and compare the color of the floor during the installation process, put similar or similar colors together, or install the floor with a large color difference to a hidden position, it must cause the owner to feel that the color difference of the floor is large.

3) Environmental factors: Generally, the color of the floor near the window is significantly brighter than the color of the floor in the dark position, which is mainly affected by the visual color difference of the floor caused by sunlight.

It is normal for the floor to have color difference, not a quality problem.

The reason for the color difference of solid wood flooring.

First of all, hardwood flooring is made from vast forests, and with the sharp decline of timber resources and the introduction of international restrictions on timber exports, the scope of timber that can be cut has been greatly limited. This means that the choice of good wood used for flooring production is greatly reduced, and the wood used for the same batch of flooring products may come from different regions.

Secondly, the growth of trees is greatly affected by light, and the wood on the light-receiving and backlit surfaces will show different hues. There is also a difference in color between the wood near the roots and the woods near the treetops, and in general, the wood made of wood closer to the roots and the heart of the tree is darker in color and heavier.

Third, due to the porosity of the wood, different parts are sparse, which makes the degree of absorption of paint inconsistent; The different direction of the floor opening (radial or tangential) will also cause inconsistent floor texture; Different light angles produce different color spots, which is also prone to chromatic aberration.

The raw materials of the basketball court wood floor come from the natural solid wood in nature, because of the different living conditions of the log and the sunshine, so the color difference is inevitable, and some basketball stadium staff do not understand, for the color difference problem, resulting in cognitive confusion, that the color difference is a product quality problem. The specific reasons for the color difference of the wooden floor of the basketball court:

Solid wood sports flooring.

1. The color difference between the roots and the treetops.

The main raw material of the basketball court wood floor is the raw wood material, some of the solid wood flooring is made of tree roots, some are made of tree tops, the color is dark near the roots, and the color is light near the treetops.

2. The color difference between the bark and the heart of the tree.

The wooden floor of the basketball court is made of light color and light weight near the bark of trees; Near the center of the tree, it is dark in color and heavy.

3. The processing method leads to color difference.

The main production material of the basketball court wood floor is logs, and the overall cutting method of the log is different, some are cut by radial, some are cut by chord, the texture of the floor is inconsistent after processing, and the two floors with different wood grains will inevitably have color difference visually.

4. Installation factors lead to color difference.

Because there is a color difference in the wooden floor of the basketball court, if the installer does not observe and compare the color of the floor during the installation process, it will be obvious if the two floors with a large color difference are put together.

5. Environmental factors lead to color difference.

Generally, the color of the wooden floor of the basketball court near the window is significantly brighter than that of the floor in a dark position, which is mainly affected by the visual color difference of the floor caused by sunlight.

As with buying apples, it is impossible for every apple to grow into one apple. Only approximately. Wood is also a natural thing.

1. Through the growth environment.

The surface layer of domestic sports wood flooring is all from the northeast maple forest area. As a high-quality maple production area, the maple here has a shorter growth cycle, longer winters, fine wood structure, and small overall color difference.

Therefore, when you purchase sports wood flooring, you should go to the sports wood flooring manufacturers in the production area with better raw materials.

Hardwood flooring. 2. Harvesting standards.

In addition to the strict requirements for the diameter at breast height and the year of growth, the yin and yang sides of the same batch of felled floors should be consistent. It ensures that the growth conditions of the same sports wood floor are the same, and the color difference can be controlled to a large extent.

3. Floor grade.

Before the installation of the sports wood floor, it will be graded according to the requirements of the site level and the color difference of the sports wood floor. The sports wood flooring with small color difference and good visual effect is selected as the surface layer of professional sports flooring, and the obvious color difference is used as the surface layer of other sports flooring.

1. Internal factors.

The discoloration of sports wood flooring is mainly caused by absorbing sunlight, and the degree of discoloration of the sapwood of the wood is different from that of the heartwood after absorbing sunlight, which will lead to a certain color difference after the pavement. Sports wood flooring is made of solid wood, which has the natural properties of wood, and the photodiscoloration produced is a normal phenomenon, not a product quality problem. The discoloration of most woods changes from light to dark, and only a few woods change from dark to light, and the discoloration on the same floor is basically the same.

Therefore, the paved floor should not be exposed to the sun for a long time, and the necessary shading measures should be taken appropriately.

Solid wood sports flooring.

2. External factors.

In the process of sports wood floor paving, the moisture content of most of the ground is about 20 percent, in the process of floor paving, if the moisture-proof film is damaged, when the geothermal heating, a large amount of moisture escapes into the floor from the damaged place, resulting in a sharp increase in the moisture content of the floor, and some soluble substances in the wood are dissolved and some color-changing bacteria are involved, resulting in wood exhaustion and annihilation or blue displacement.
