How to deal with the stone Baihua problem?

Stone formation of Baihua factors and water spots are similar, a large amount of water, alkaline metal ions are the cause of Baihua, which plays a role in the destruction of the belt, the basic metal ions after the dissolution of the capillary phenomenon infiltrated into the stone surface or filling is not real, further formation of Baihua.Therefore, the prevention of water and basic metal ions infiltration into the stone surface or filling is not solid, you can prevent the occurrence of Baihua.

Measures to prevent the formation of Baihua are as follows:

One, stone before installation should be applied as a protective engineering (front, five or six sides, depending on the project needs), prevent stone inhalation too much water, prevent from the front of the stone or underground water infiltration of cement mortar under the stone, in order to avoid the basic metal ions of cement mortar infiltration stone, resulting in baihua.

Two, the selection of suitable for stone gap filling materials, and according to the correct construction method to apply.Good quality caulking materials and correct application methods can prevent the occurrence of whiteness at caulking.

Three, in the deployment of cement mortar, the use of low water cement ratio or add water reducing agent.Reduce excessive water content, can avoid a white bloom.

Four, the addition of waterproof agent in cement mortar, can avoid metal ions by a lot of water to dissolve and exudate the stone surface to form Baihua.

Five, the selection of pollution-free aggregate, such as avoid the use of calcium, magnesium, sodium plasma more sea sand, and avoid the use of minerals more groundwater as mixing water, reduce the source of metal ions, reduce the probability of white Chinese.
