Reference to nanotechnology for stone conservation

Due to the deterioration of the natural environment, dust, industrial waste gas, acid rain, etc. are very likely to pollute the stone, and some of the stone itself is poor in material, and then the stone water spots are not dry, white, yellow, rust and other stubborn diseases. How to control the variation of stone has become one of the top considerations for architects, construction companies and owners.

The development of nanotechnology involves many aspects of our daily lives, and the protection of stone is only one of them. Here, we make a simple analysis of the protective effect of nanotechnology on stone surfaces:

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

After the surface of the stone is treated, the protective agent penetrates into the micropores of the stone to form a strong and long-lasting protective layer. The polymer skeleton group is firmly combined with the stone, and the group on the side chain of the polymer skeleton forms a hydrophobic and oleophobic layer on the outer layer. . The protective agent added with nano material forms a protective layer on the surface of the stone. When the liquid is in contact with the surface of the stone, the surface of the stone becomes smaller, the stone is not wetted by the liquid, and the liquid is prevented from penetrating into the interior of the stone through the capillary hole, thereby solving the problem. Various pathological problems of stone.

2. The stone surface protectant using nanotechnology has excellent weather resistance:

The stone surface protectant using nanotechnology has a matrix material as an organic polymer material with excellent performance, and has remarkable characteristics of molecular structure stability, excellent weather resistance, good hydrolysis resistance, good chemical resistance medium, good solvent resistance, and thus stone protectant It has excellent weather resistance and can protect stone for a long time.

3, the use of nanotechnology stone surface protection agent has a strong permeability:

The nanoparticles are extremely small, have low viscosity, good fluidity, and are extremely permeable, and can penetrate into the microscopic voids inside the stone to a depth of 1 to 2 cm. It is possible to maintain the stability of the protective properties for a long time.

4, the use of nanotechnology stone surface protection agent has a strong wear resistance:

The nanoparticles are extremely small and can penetrate into the interior of the stone, forming a whole with the stone, not just forming a film on the surface of the stone, so it has very good wear resistance, and even plays a protective role after the stone is worn away by 1 cm.

5. The stone surface protectant using nanotechnology has transparency:

The nano-material forms a film on the surface of the stone and covers the entire surface of the stone. Due to the presence of the nanoparticles, the pores caused by the stone defects are filled, and the surface film does not affect the normal breathing of the stone matrix. The film itself is colorless and transparent. To ensure the brilliance and moisturization of the stone, it will not have any effect on the appearance of the stone.

Ming and qing furniture parts name. That is opposite sides-to hold, also called  Lead Screw. Gb did not find the corresponding standard, corresponding DIN975. For different position and different name. Generally refers to surface under the box set connection between his legs and components. A beam waist furniture is in the beam waist the following parts of the main connection parts. In other parts of the general was renamed as a tooth. In addition, still use in architecture, with the most decorated.
