Is the color difference of the floor a product quality problem?

1. Is the color difference a quality problem?

This question has to be divided into two parts. The color difference of one side sports wood floor is a natural phenomenon. Why do you say that, because the main raw material for the production of sports wood flooring is solid wood raw materials.

The growth environment of logs is different, and the color of log materials in different origins is different; Different parts of the same tree have different wood colors. Therefore, there is no such thing as a sports wood floor with no color difference at all;

On the other hand, the color difference of sports wood flooring is also a real annoyance. It is conceivable that in the main sports area of the stadium, if the ground color difference is serious, there will be a sense of intricate and messy. Therefore, the color difference of sports wood flooring still affects the sports environment.

2. Color difference is not a quality problem.

According to the relevant person in charge of the Consumer Association, there have been many complaints about the "color difference" of the floor recently, and some owners have used this as a reason to claim compensation from the flooring business. The person in charge pointed out that under the premise of meeting the quality requirements, the flooring business refused to compensate the other party for losses.

Due to the properties of wood, it is normal for solid wood flooring to have color difference, which generally does not constitute a quality problem, and the "color difference" of the floor is not a quality problem.

At present, neither the national standard nor the enterprise production standard takes the color difference as the standard for testing the quality, and the state has no clear regulations on the "color difference" of solid wood flooring.

Ms. Feng in Beijing bought a solid wood floor of nearly 300 yuan per square meter, after the paving, very troublesome, but there is no problem, just feel that the color difference of the floor is too big, the pattern is in the shape of a big flower face, the psychology is very unbalanced, and the manufacturer is required to replace, but after several complaints, it has not reached a full explanation, that is, the consumer's requirements are reasonable and unreasonable? Or does the state have special regulations on the color difference of the floor? To this end, we visited the Wood Floor Circulation Professional Committee of the China Timber and Wood Products Circulation Association and asked experts to give answers.

The floor is composed of wood, it is processed into wood through trees, and finally made into floor, there is a series of technological processes, then in the growth process of trees, there are core materials, cuts, roots of the tip of the wood, the heating site has a sunny slope, a tree's core material and cut, root and tip wood, sunny slope and shady slope wood because of the difference in light and moisture, the color difference is not the same. Color difference is not only caused by the structure of the tree, but also related to the sawing surface, radial cutting, rotary cutting, oblique cutting will cause color difference changes, about the color difference of the floor, the psychological tendency of consumers is no color difference, in fact, this is an unscientific backward consumption concept, as the wood itself, color difference is allowed, this is a natural attribute, for this reason, the state does not stipulate the color difference of the floor. We believe that laminate flooring can achieve the consistency of the color of the floor, because it applies a printed pattern texture on the surface, but in order to catch up with the fashion and cater to the psychological needs of consumers, consciously artificially create color difference, natural curves, scars, cracks, etc., and these novel floor structures are often recognized and loved by consumers, but they feel that they are very environmentally friendly and fashionable, and the natural solid wood floor has this texture structure, but consumers can not accept it, so there is a contradiction.

First of all, consumers need to change this notion that there is no color difference.

Secondly, we want to have as little color difference as possible, and less is not the same as no color difference. Experts believe that it is natural to allow color difference and free paving, but if you consciously avoid color difference, it is not good.

After the arrival of the floor, we must carry out the quality acceptance, look at a box to check the color difference of the floor and other quality problems, carefully check the color difference of the floor, see whether the color difference is satisfied, do not pave if you are not satisfied, and shop if you are satisfied.

At the laying site, it is recommended that the pavement worker test lay the floor in each house first.

This is not a fake and shoddy product, generally when taking pictures, because of the lighting or camera, the color of the floor will be shallower than the real thing, and the floor has undergone post-processing.

It is not a fake and inferior product, because the log itself has color difference, so the solid wood manufactured will also have color difference.

Yes, if the solid wood floor has a color difference, it means that it is a fake and shoddy product, and you can find a merchant to protect your rights reasonably.

When consumers buy floors, they often find that there are differences in the color of the floors, which is commonly known as color difference. The color difference often becomes the focus of controversy between consumers and merchants, and it is often the worry of buying and the crying of grievances when selling.

In fact, the color difference of solid wood flooring is allowed, and there is no special provision for the color difference in the "National Standard of the People's Republic of China for Solid Wood Flooring".

So what is "chromatic aberration"? How does "chromatic aberration" come about? How to solve the "color difference"?

1. What is "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.

There are generally two ways to express it: one is based on subjective feelings. The color difference is divided into several grades and made into a standard sample card as a basis for relative comparison.

The other is measured with a colorimeter, which is compared by manual calculations or by the instrument automatically displaying the data given. NBS (National Bureau of Standards) color difference unit is commonly used in the world, and the color difference of one NBS unit is difficult to detect under general conditions.

2. Why does "color difference" occur?

From the cut surface of the wood, we can understand the principle of the formation of wood color difference. In the process of natural growth, affected by climate change and differences in soil conditions, different parts of the same wood naturally form different colors and textures.

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. The color of wood is formed by objective factors such as various pigments, resins, gums, tannins and oils contained in wood cells. The wood color of the same tree species varies due to factors such as dryness and wetness, cross-sectional age and location (heart, sapwood), exposure time to the air, discoloration of decay and fungal infection, and height and site.

Some of the floors in a box are made of tree roots, and some are made of tree piggybacks, and the floors near the roots of the trees are dark in color and heavy; Near the treetops are light in color and light in weight; Near the bark of the tree is light in color and light in weight; Near the center of the tree, it is dark in color and heavy.

Therefore, it is found that the color of a box of floors is sometimes inconsistent, and the weight is not the same.

3) "Wood floor color difference" is not a quality problem.

It is unrealistic to demand consistency in the natural color difference of solid wood flooring. Solid wood floor must have color difference, color difference is natural, inevitable, this is determined by natural attributes, therefore, the country in the development of matching standards, there is no requirement for color difference. Therefore, it is normal to have a slight color difference during installation.

4) How to solve the problem of "color difference".

In order to avoid the impact on the overall appearance of the living room due to the excessive color difference of the wood floor, we will carry out trial paving during the paving, and at the same time gradually transition in the paving process, and the floor slabs with similar colors will be spread together, and the rest can be spread under the bed, wardrobe and sofa to reduce the visual 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.

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.

In general, slight color differences are allowed on the floor, but only to the extent that they are difficult to distinguish with the naked eye. If you can intuitively distinguish the excellent difference, and the color difference is serious, it is recommended to contact the seller. Ruicheng flooring screens the floors of the assembly line one by one through manual inspection to minimize the color difference.

The vast majority of floors have color differences.

The color difference of the floor is relatively small.

The general floor color difference is relatively large.

The flooring seller should tell you.

However, the color difference of the same batch of floors is basically the same.

It's just that there will be a little color difference between the sunlight and the backlight.

It shouldn't be much worse.

It is generally not visible to the naked eye.

Hello, first of all, I need to tell you that there is absolutely a color difference in the real solid wood floor, because the raw materials of the pure solid wood floor are generally divided into three kinds of ABC, of which the A board is the best and the heaviest is the most dependent on the roots of your trees, so it also causes the color difference of the pure solid wood floor.

It may be to buy ** low flooring, in fact, you get what you pay for.

If you spend a lot of money, the purchase of the upper level of the floor still has a large color difference, that is the manufacturer's problem, let me explain to you the origin of the color difference.

First of all, a towering tree, the wood of its various parts is not the same, the wood at the root is tighter, harder, and the oil is higher; The wood in the upper part or in the treetops is softer, with less grease and softer wood. Then this big tree is made into logs, and the log dealer cuts it and sells it to the flooring factory, which must be in a batch of goods. Even if the color tone of the paint is exactly the same in the processing process, there will be a variety of color differences in the wood itself in the case of the same color.

After manual selection, the same color is divided into a column. Therefore, when customers buy flooring, in fact, the commodity board has actually been classified. Then there can be quality problems, then there can only be 3 reasons, 1:

The manufacturer's coloring technology is not in place, and it cannot maintain the unity of color in the processing process. In general, the color will become lighter and lighter the more it is processed. 2：

In order to save costs, manufacturers will mix non-conforming products into qualified products for sale, which can save a lot of costs; 3: The brand has a small market share and is unwilling to invest too much money in the diversity of varieties, so it maintains a high color difference in color difference to save the cost of multiple inventory caused by multi-color, so the color difference of each variety is relatively large. 4：

There is an error in the selection of board by factory workers, which is mainly caused by the factory environment, and some small workshops are dimly lit and not suitable for floor processing at all. ——The answer from the swallow mud floor, typing is hard, I hope to adopt. If there are any flooring problems in the future, please go to the local Yanni flooring franchise store for consultation, and we will serve you wholeheartedly.

Many people pursue the same color in the choice of solid wood flooring, in fact, it is normal for solid wood flooring to have color difference, and the solid wood floor without color difference is probably not a good floor!

1. Solid wood flooring is derived from natural wood, and the solid wood floor near the roots of the tree is dark in color and heavy in weight; Near the treetops are light in color and light in weight; Near the bark of the tree is light in color and light in weight; Near the center of the tree, it is dark in color and heavy.

2. Wood is a porous material, and the material density of different parts is different, so the texture is inconsistent; Each part attracts different amounts of light and paint, so the shades of color are inconsistent. In general, the color difference of wood species with large and coarse patterns is larger, and the color difference of wood species with small and delicate grain is smaller. The overall feeling of the floor pavement with large and coarse texture is rough, natural, and has a wild beauty; The small and delicate texture of the floor is refreshing, clean, there is no absolute good or bad, just a different style.

Third, the opening direction of the solid wood floor is different (such as some solid wood floors are cut radially, some are cut by chords), the texture of the solid wood floor is inconsistent after processing, and the color difference will also appear on the visual appearance of two solid wood floors with different wood grains, which requires careful adjustment by the installation workers.
