Nanotechnology applications in the stone protection

Source: Time:2014-05-01 09:02:48 frequency:

due to the deterioration of the natural environment, dust, industrial waste gas, acid rain and other easily polluted and some stone, stone material itself is poor, and the stone water spots not stem, Bai Hua, spit yellow, rusty spot disease. How to control the variation of stone, has become one of the architectural designers, construction companies and owners of the three parties considered to the first problem.

due to the deterioration of the natural environment, dust, industrial waste gas, acid rain and other easily polluted and some stone, stone material itself is poor, and the stone water spots not stem, Bai Hua, spit yellow, rusty spot disease. How to control the variation of stone, has become one of the architectural designers, construction companies and owners of the three parties considered to the first problem.

Development of

nanotechnology involves many aspects of our daily lives, stone protection is an application of the. Here, we on nanotechnology in the protective effect of the stone surface will make a simple analysis:

Stone material surface protecting agent

1, using nanotechnology has good waterproof and antifouling effect:

stone surface after treatment, protective agents to infiltrate the stone is formed inside the firm, microporous lasting protection layer, polymer skeleton groups and stone firmly, while the polymer backbone side chain groups in the outer layer forming hydrophobic, sparsely reservoir. Protective agent adding nano material to form a protective layer on the surface of the stone, when the liquid and the stone surface contact, due to the surface tension is smaller, the stone will not be liquid wetting, avoiding the liquid through pores into the stone, so as to solve the problem of various diseases of stone.

Stone material surface protecting agent

2, using nanotechnology has excellent weather resistance:

using nanotechnology stone material surface protecting agent with the matrix material for high performance polymer materials, has the advantages of stable molecular structure, excellent weather resistance, hydrolysis resistance, chemical resistance, solvent resistance, stone protective agent which has excellent weather resistance, can be a long time to protect the stone.

Stone material surface protecting agent

3, using nanotechnology has strong penetrability:

nano particles are extremely small, low viscosity, good fluidity, with strong penetrability, which can penetrate into the interior of the stone micro voids in the depth of 1~2 cm. Protective properties can keep stable in a long time.

Stone material surface protecting agent

4, using nanotechnology has extremely strong abrasion resistance:

nano particles is very small, can penetrate into the interior of the stone, forming a whole with the stone, and not just the membrane formed on the surface of the stone, therefore has wear-resisting performance is very good, even in the stone mill off after 1 cm can also play a protective effect.

Stone material surface protecting agent

5, using nanotechnology with transparency:

nano materials in the film covering the entire surface of the stone, the stone surface, due to the presence of nanoparticles, fill the stone defects caused by pore, and this layer of film does not affect the normal breathing of stone matrix, the film itself is colorless and transparent, can guarantee the stone brilliance and moist, not have any impact on the appearance of stone.
