Stone pollution early prevention of correct design is the key

In general, stone pollution prevention is more important than cleaning. Daily long-term maintenance results are better than sudden acute cleaning. Dirt contamination can be reduced and prevented by proper design and material selection, careful construction and maintenance. The so-called correct design, that is, attention to the following things happen to the pollution of sandstone products:

When the product is subjected to plane processing, externally sloping wall cap stones, the use of wall cavern drainage is not required, the waterway flows into the constricted part of the structure, the water flows through the concrete, glass or other building materials, and the surface of the sandstone is easily exposed to sandstone. Products cause pollution. In special circumstances, materials that match the nature of the stone should be selected. For example, when used as a wall lining, it is necessary to protect the front of the elevator, the vicinity of the lift switch, furniture, and the like. Combinations of incompatible materials are prone to contamination. For example, a car leaks from a liquid on a sandstone surface. The permeable mortar laid on the deck or stairs will become coal-based pollution. Incorrectly cleaned seams are also an important reason.

The correct treatment measures include careful attention to transportation, storage, and construction. Thin panels are not only crisp and fragile, but they are easily stained. Attention must be paid to stubborn stains such as grout, paint, protective layer stains, scaffold rust, and mechanical lubricants.

From the storage period to the end of construction, the stone must be covered with a plastic or anti-fouling cloth as much as possible.

A thorough understanding of the entire service process may result in internal and external contamination due to contamination or human contact. Must be isolated from the source of pollution as much as possible, often removing dirt and so on. In contaminated areas, clean the stains with appropriate paint and construction cleaners. When cleaning the stone, it should be moderate to prevent damage to the environment and workers or damage to the stone itself. Taking into account the cost factor, cleaning should be cost-effective. Therefore, you must be familiar with the following:

1. Clean and convenient methods and places;

2. The feeling of loss caused by the stone when cleaning;

3, the degree of surface contamination;

4, whether it must be cleaned.
