Granite curbstone maintenance knowledge

The appearance of the material looks very hard, it seems to be a wear-resistant and corrosion-resistant building material.But because the natural stone itself cracks and pores with adsorption and permeability, this has become the root cause of stone aging and a variety of diseases.And marble is to be composed by calcareous, granite is to be composed by silicate kind mineral, because this is extremely easy with the chemical substance that goes against stone material to maintain produces reaction.The protection of natural stone should be like the protection of our body, if you do not pay attention to maintenance or maintenance methods are not correct, will make the stone natural noble, elegant temperament style disappeared.

Luyandan belongs to a small part of the granite stone, is a kind of pure natural products for a variety of building stone, it has the very strength of texture, acid and alkali resistance, resistance to weathering, colour and lustre is bright, but no matter what kind of stone material have a common weakness, that is, after use, if does not carry on the maintenance, stone will appear all sorts of pathological changes, shorten the life of stone.

So to maintain the granite roadside stone need to master three points;

1, the stone along the road should prevent dry crack

Although the stone environment can not be in a wet and dark place, but also can not be in a particularly dry place, to maintain a certain humidity, but not wet oh, if the stone has been in a dry environment, it will absorb the water inside the stone, the surface of the stone will appear the phenomenon of cracking.

2, stone to prevent heat

Stone if often in the strong photometric exposure, with the rise of temperature, will make the luster of the stone changes.

3, the stone along the road should prevent acid and alkali

Stone material chemical composition is basically neutral, when installation should pay attention to had better not install to the chemical composition of too much, afraid of acid and alkali, stone material come into contact with a lot of acid and alkali ingredients of the material can make the stone found that corrosion, and at the time of curing, curing agent products are not free to use, a lot of products containing alkali ingredients, also have threat to stone.
