    Application of nanotechnology in stone protection
      Source       Views 983       Time 2019/12/12 05:29:41

    Due to the deterioration of the natural environment, dust, industrial waste gas, acid rain and other easy pollution of stone, and some of the stone material itself poor material, and then produce stone water spot dry, white, yellow, rust spots and other stubborn disease.How to control the variation of stone material has become one of the primary concerns of architects, construction companies and owners.

    The development of nanotechnology involves many aspects of our daily life, and stone protection is just one application.Here, we are looking at nanometrics

    A simple analysis is made on the protective effect of stone surface:

    1. The stone surface protection agent using nanotechnology has good waterproof and antifouling effects:

    After the treatment of the stone surface, the protective agent penetrates into the inside of the stone micropore to form a strong and durable protective layer, and the polymer framework group is firmly bound to the stone

    The groups on the side chain of the polymer skeleton form hydrophobic and hydrophobic layers in the outer layer.Add a nanomaterial protector to the stone surface to form one

    Protective layer, when liquid and stone material surface contact, as a result of surface tension decrescent, stone material won't be wetted by liquid, avoided liquid to pass wool stoma to infiltrate stone material interior, solved all sorts of pathological changes of stone material problem thereby.

    2, the use of nano-technology stone surface protection agent has excellent weather resistance. The use of nano-technology stone surface protection agent matrix material for excellent performance of organic polymer materials, with the remarkable characteristics of stable molecular structure

    , good weather resistance, hydrolysis resistance, good chemical resistance, good solvent resistance, stone protective agent therefore has good weather resistance, can protect the stone for a long time.

    3, the use of nanotechnology stone surface protection agent has a very strong permeability nanoparticles are extremely small, viscosity is low, good mobility, with a very strong permeability, can be penetrated into the stone internal micro gap 1~2 cm deep

    .It can maintain the stability of protective property for a long time.

    4, the use of nanotechnology stone surface protection agent has a very strong wear resistance nano particles are extremely small, can penetrate into the stone internal, and stone form a whole, not only in the stone surface formation of film, so has a very good wear resistance, even in the stone after 1 cm can play a protective role.

    5. The stone surface protection agent using nanotechnology has transparency:

    Nano materials in stone material surface film, covering the whole stone material surface, because of the existence of nanoparticles filled stone defects caused by the pore, and the layer surface film does not affect the normal breathing of stone matrix, and the film itself is a colorless, transparent, can guarantee the stone of splendor and moist, won't cause any influence to the appearance of the stone.
