Protection Process for Subway Construction’s Decorative Stone

Updated:2013-02-17 17:15:24
Protectant is a fluoro-containing organic silane, siloxane oligomers, additives, organic solvents, complex environment composed of a single-component product, a colorless and transparent liquid, can effectively penetrate the capillary channel stone infringement, effectively prevent the water stone plaque, not everyone agrees, pitting and other symptoms appear.

You could take the following protective mechanism into account. Permeable protective agent protective process includes the following three phases:

Phase 1 is the infiltration process: In accordance with "Principles of the pores," protective agent through the tiny pores in the surface of stone, penetrating into the stone within the surface appearance of this stage is "adsorption".

Phase 2 is the filling process: namely, the deepening penetration of the process, Protectant stone along the main vein within the capillary pores, penetration into the offshoot, in the stone house has a certain depth within the surface evenly distributed throughout the penetration of the region gradually filled with tiny capillary pores, and attached in the hole, the phase of the appearance of "invasion."

Phase 3 is the crystallization process: the full infiltration of the liquid inside the stone, along the tiny capillary pores begins to crystalize into a tiny crystal ball, and gradually filled the capillary pores by infiltrating the main veins and spur, between the micro-crystal sphere "Qi Lu", its size is about one-thousandth of the diameter of droplets, thus making it difficult to pass water droplets into the stone surface of the porous stone house; the same time, because the size of another 100 times for the air molecules, enabling a smooth stone water vapor within the original along the "air route" Run to the stone surface of the material has not impede the "free breathing" function. Stone not only in order to ensure good air permeability, but also has excellent waterproof, anti-fouling properties.
