First, how to prevent?
1. Mining, processing and transportation
1 Pay attention to avoid the influence of rust on machinery and tools on white stone in all aspects of mining and processing. If there is rust, find a way to remove it.
2 Prevent the use of wood in all links to cause pigmentation on the stone. If you can give these woods, you can also apply osmotic protective agents.
3 When doing protection in the factory, it is necessary to abandon the practice of only paying attention to the cost. It is forbidden to use non-professional protective agents and inferior protective agents, and to choose high-quality penetrating protective agents.
2, the installation process
1Be sure to do the six-sided protection of the stone before installation. Moreover, the back side of the protection, it is best to use professional grade stone adhesive to seal.
2 If possible, use an adhesive instead of a cement wet sticker.
3 The stone that was originally protected should be re-cut according to the actual situation, and the protective effect will be lost again. Therefore, as long as there is a cut, the brush is re-applied.
4 When installing, try to avoid the cement spilling onto the stone surface. Because the protection is even better, the stone also has micro-cracks, and the alkaline component of the cement penetrates into the interior of the stone along the micro-cracks, and it will still cause yellowing.
5 When using various types of glue, choose a quality product and follow the specifications.
Second, give us inspiration
We can also see that there are so many links involved in preventing the yellowing of white stone, and the knowledge involved is so wide. And once it goes wrong, the cleaning technology is so complicated and time consuming.
What does this give us?
That is, in the entire stone industry, mining, design, processing, installation, nursing and other aspects involving the whole process of stone application, but also lack of communication and collaboration. If there is good communication and coordination between each other, many stone problems can be solved from the source.
