Many people will have color differences after buying ceramic tiles for a period of time, which makes many people annoyed and puzzled. Obviously this phenomenon did not occur when they purchased it! Why does this happen after use? So, What causes color difference in ceramic tiles?
Zhong Taojun listed the following possible reasons:
1. Improper soaking of porcelain tiles
Due to the high water absorption rate of porcelain tiles, they must be soaked in water before paving. If the porcelain pieces are not fully soaked in water, or the soaking time is very different, the moisture content of the green body will be uneven. There will be "color difference" for a period of time after paving. After natural air drying, this color difference will gradually disappear. In addition, if the waterproof layer is not constructed properly, this type of color difference will also occur.
Solution: When soaking in water, pay attention to the water depth, time, and number of tiles. After the tiles are "full of water", take them out and dry them. There will be no watermark on the surface before paving.
2. Mixing different batches and color numbers together by mistake
Even ceramic tiles of the same model will have a reasonable color difference to a certain extent. If you do not read the packaging clearly before paving, and mistakenly mix ceramic tiles of different batches and color numbers together, it is very likely that the color will be different after the paving is completed. Disconnections and unnatural connections occur.
Solution: Pay attention to the color number and batch before laying, and ensure that the same batch of tiles are laid in the same space.
3. Paving factors
It is said that ceramic tiles are semi-finished products, and only the tiles that have been laid can be considered finished products. Therefore, if there is an error in the laying process, color difference may occur.
4. The color layer is broken due to secondary cutting
The deep processing application of ceramic tiles can show more flexible and changeable paving effects. However, if the cutting operation is improper, the color layer of the product will be broken, resulting in color difference. Or when ordinary paving without trial paving, it will also easily cause The overall effect is inconsistent.
Solution: When paving secondary processing patterns such as parquet, conduct effective trial paving according to the directionality of the texture.
5. Ceramic tile factors
In addition to the color difference caused by improper paving, some ceramic tiles themselves have intentional color difference effects. The purpose is to make the texture more realistic and the connection effect to be harmonious and smooth, just like real stone.
For example, ceramic tile products with imitation marble and jade textures. Since the pieces of natural stone are different and the texture is full of changes, many merchants, in pursuit of this realistic effect, also strive to create a transition between dark and light textures on the ceramic tiles.Inconsistent effects. This "color difference" is by no means a quality problem.
Solution: When selling ceramic tiles, the shopping guide should clearly inform the attributes of the ceramic tile category so that consumers have a clear understanding of this category.
6. Process factors
During the firing process of ceramic tiles, a certain degree of color difference will occur due to various factors such as raw material quality fluctuations, pigments, ball milling fineness, color particle size and gradation, color ratio, forming pressure, firing conditions, cloth, etc. In other words, it is difficult to make identical tiles. Generally speaking, if the overall paving effect is color-coordinated, the texture is consistent and harmonious, and there is no obvious difference, the color difference in this case is not a quality problem.
7. Product instability
Color separation error when shipped from the factory. When ceramic tiles leave the factory, they should undergo strict color separation screening, and products with obvious color differences should be processed. If the graders are "lazy", it may lead to the appearance of ceramic tiles with obvious color differences in the same batch.
8. Other factors
"Color aberration" caused by light differences. Due to the difference in light and shade, the display effects of ceramic tiles will also be different. For example, when the ceramic tiles are displayed in the sample room, the gloss will be brighter, but when they are laid, the brightness of natural light and lights will be different, resulting in differences in visual effects. .
Solution: Consumers should fully consider the visual impact of light. If necessary, they can ask the shopping guide to move the tiles to natural light for display.
The above is about the reasons for the color difference of ceramic tiles. I hope it can be helpful to you. Come on!
