Why does sesame black lychee granite fade?
1. The use of sesame black lychee granite stone is not fixed. It has many capillary like structures inside, and various oils and dirt can easily enter its interior through the capillaries. Due to the natural environmental properties of granite stone, some companies are unable to change their internal control structures, and the stone contains a high amount of iron minerals, which can easily cause rusting under the action of water.
2. During the use of stone, fine sand particles or sharp objects may wear down the surface of some stones. In this case, repair and refurbishment are required. Place sesame black granite in areas primarily used outdoors. Due to the influence of natural environment, such as high temperature, acidic gases, ultraviolet rays, water vapor, and weather, the surface changes color and loses luster. Therefore, in order to effectively extend the service life of color retention coatings, we should dye and brighten the stone.
3. Compared with other stone materials, sesame black lychee faced granite stone has high hardness, strength, and is not easily weathered or deteriorated. The processing technology of sesame black lychee granite stone is to cut the ore image of Wulian stone mine into waste, use a large stone saw to cut it into strips, then polish, round, chop the shaft and other treatments, and then burn it into finished products to prevent fading.
