With rapid increase of human material and culture living standard. The pursuit of luxury and beauty, advocating a return to nature has become the trend of architectural art, decoration art. Natural stone is a fascinating beautiful material, it has a gorgeous color, unique luster. Elegant, elegant and generous. Can bring the natural and luxurious beauty to ^. From the luxury hotel, shopping malls, to the general family of the ground, there are traces of stone filled everywhere. Natural stone price is more expensive, as a general contracting construction enterprises, especially decoration enterprises, how to maintain the natural beautiful natural stone, is one of the main issues we consider.
With granite, marble as the main natural stone texture. A variety of colors and varieties. Because it has a unique organizational structure, strong and durable, enjoy the eternal beauty of the world, is an ideal building decoration materials. Although the rain, if in accordance with the traditional construction process, this "eternal" is also short. Sheng nearly learned some item of our company. In the stone construction and maintenance has encountered some problems. Below. Write out what I have learned. And share with you.
First, the characteristics of stone
Stone village, due to their infinite variability in water absorption, density, hardness and other properties, looks hard, durable. In fact, Ishimura's pores, such as human skin. Breathing when the bacteria in the air, dust, microorganisms and other suction at the same time, can also be corrosion, weathering. With the development of modern industry, the global environment is becoming worse and worse, exacerbated by the stone village of corrosion and pollution, and then produce water spot does not stem, Baihua (i.e. Fanjian), vomit, rust and other chronic and stubborn disease, stone accelerated deterioration. At present, high-tech stone conservation products and technologies, professional treatment of stone buildings, stone before installation, first on the stone were effective protection processing, after installation of the necessary maintenance, will be "eternal" keep a
Two. Stone conservation products classification and its characteristics
(first) from the functional division
1. A series of protective materials: sealed by penetration of the protective agent, in the stone surface provides a way of long-term, see see, advanced oil proof, waterproof, anti fouling barrier to prevent stone is corrosion, pollution, generally in the construction process using.
2. Stone cleaning series: the use of a variety of material combinations, effectively broken and stripping dirt; or is the use of a substance to neutralize oil. Synthetic compounds can be separated from stone, generally used for wave pollution of stone cleaning, renovation.
Bright, surface strengthening series: coating sealing protective agent of the increacing 3 stone to prevent slippery. To form a surface protective film, with non slip increase bright surface enhancer to non slip brightening and strengthen the intensity of the surface coating, the stone for maintenance.
(two) division from the matrix
1 solvent based protective agent: there are volatile, some smell, on the environment and health hazards.
2 water based protective agent: not as solvent based products in the presence of harmful solvents, the first smell. No harm to the environment and health, green environmental protection products, and visible flame
Three. Standard of good or bad stone protective agent
In the construction enterprise, the most contact should belong to the stone protective agent, its measure is roughly:
1 has a lower water absorption value, and the lower the better, generally 0.11%.15%:
2 have good permeability: (anti aging performance is good)
3 no by-product; (normal byproduct is water and alcohol)
4 fewer residues (for wool board, this requirement is not strict; in the plate residue affect the appearance)
5 higher covering rate:
6 easy to use;
7 low volatility. (mainly refers to the volatile solvent. The most ideal protective agent for the solution
Four. Select the factors that should be taken into consideration in the stone protective agent
1 types of stone, such as: marble, granite, etc.;
2 characteristics, such as surface condition (stone plate, wool board), pore size, density, hardness, stone composition etc.:
3 the selection of the protective agent and the mineral composition of the stone match:
4 environmental conditions, such as: indoor, outdoor, humid environment, climate conditions, etc.;
5 selection of the indicators and service life of the protective agent.
Five. Stone protective agent construction process matters needing attention
1 before the use of protective agents, to confirm that all the required surface has been thoroughly cleaned, without any silt and particles;
2 the protective agent should be brushed on the surface of the stone which is no longer being processed, and not used for re processing of the stone surface. If used for re processing of stone, the application of infiltration, but more waste;
3 in the stone tree processing, feeling washed, dry (about 72 hours), the brush is better;
4 construction, the brush to dip full brush, the stone will be placed better;
5 finished the first brush, after the protective agent into the brush and then brush second times the best;
6 for silicone products, 24 hours after the brush to do waterproof protection;
7 according to the actual situation, to determine the five surface protection or six surface protection:
8 can not use two products at the same time;
9 carefully read the product manual, and strictly comply with the implementation of.
Six, stone cleaning, rust spot
L light stone cleaning agent, singeing plate by high pressure gun cleaning;
2 can not use strong acid cleaning;
3 of foreign oil pollution, do not use oil solvent;
4 available efflorescence acid cleaning agent, good Chen, but can not be eradicated.
Above is my understanding, the accumulation of a bit of knowledge, in the Guanzhuang industrial and Commercial Bank of Xidan and Hong Kong have been used in the building, and achieved good results.
Stone conservation has been widely used in foreign countries, and in our country, it has not attracted the attention of people, whether it is the owner or the construction side, the stone conservation are poorly understood. For architectural decoration construction enterprises to improve their competitive ability, it should absorb the advanced experience and adopting new materials, new processes, from the construction process to create quality, our concept of the "warranty" gradually to "good quality", in line with international standards.
