What maintenance points should be paid attention to before and after installation of cultural stone

"With the development of my country's cultural stone industry, cultural stones are more and more recognized by people. People use more and more cultural stones in their lives. The cultural stones themselves are full of micropores (capillaries), and water invades people. Cultural stone produces the root cause of disease. Therefore, it is necessary to protect the cultural stone before construction. my country's current maintenance products are still in the early stage of development, and their technical performance is uneven. Care must be taken when selecting them. Regarding the protective agent, it is used in large quantities regardless of "green, red and white". Unscientific. 　　The protective effect of cultural stone is related to the performance and quality of the selected protective agent. Existing protective agents are classified into fluoride type and silicone type according to the material."

What maintenance points should be paid attention to before and after the installation of culture stone

With the development of China's cultural stone industry, cultural stone is more and more recognized by people. More and more cultural stones are used in people's life. The culture stone itself is full of micropores (capillaries), and water invasion causes the disease of culture stone. Therefore, it is necessary to protect the cultural stone before construction. At present, our country's maintenance products are still in the early stage of development, and their technical performance is uneven, so we should be careful when selecting them. As for the protective agent, it is unscientific to use it in large quantities without asking "the black and white". The protective effect of cultural stone is related to the performance and quality of protective agent. The existing protective agents are divided into fluoride, organosilicon and resin acrylic according to the materials. The performance of fluoride organosilicon is the best, with strong air permeability, excellent permeability, chemical resistance and weather resistance, which can protect the cultural stone in an all-round way. In addition, the dryness of cultural stone also plays a decisive role in the protection effect of cultural stone. The cultural stone should be dried first, then coated with protective agent, and the effect will be better if it is dried thoroughly and then coated again. Otherwise, it will affect the protection effect. The process dosage of protective agent is an important index of the protective effect of cultural stone. Due to the different structure and pore size of cultural stone, the water absorption is different. Therefore, the determination of the amount of cultural stone protective agent can not be ignored. If the amount is less, the protective effect can not be fully reflected; if the amount is more, not only the consumables and labor costs, but also the aggregate accumulation on the stone surface will affect the appearance. Therefore, we must make a model test on the cultural stone to determine the process dosage. The best dosage is determined by moistening the fossil surface with protective agent until it is completely full. For the cultural stone treated with crystal, the surface of the cultural stone shall be treated with opening pores before applying protective agent; for the cultural stone that has been put into a and has not been used as protective agent, it can be protected with & ldquo; mend the past & rdquo; to prevent the cultural stone from pathological changes. In order to keep its bright appearance for a long time, in addition to reasonable installation, protection, cleaning and routine maintenance of cultural stone can not be ignored. It is believed that after such maintenance, your cultural stone will certainly improve its service life and value. Permeability protective agent can be divided into two types: solvent and water-based. Its protection principle is that the effective substance penetrates into the interior of stone with the solvent. After the solvent volatilizes naturally, the effective substance remains in the interior and surface of stone, forming a protective barrier to prevent the infiltration of external pollution and prevent the seepage of pollution in the interior and bottom of stone, so as to maintain the original appearance of stone and extend the service life of stone The solvent protective agent has strong volatility, flammability, pungent smell, and certain toxicity, so it is necessary to keep good ventilation during construction; while the water-based protective agent is an environmental protection type protective agent, colorless, non-toxic, tasteless, non combustible, and has no impact on the environment. Any kind of penetrating protective agent can not form protective layer on the stone surface.

Why cultural stone attracts people's attention

The origin of Chinese market of a man-made cultural stone 1. the origin of art stone art brick, the stone of artifact culture, was called art stone when it first entered the Chinese market abroad. It originated from the United States fifty or sixty years ago, and it has been popular in the world, and China was introduced into Chinese mainland in 90s. It was used indoors at first Background wall decoration, Wuhan Jiacheng huiran building materials Co., Ltd. developed art stone and put it into the market in 1999. In 2003, it invested a lot of money to study outdoor art stone decoration, to solve the problems of material density and strength, water absorption, anti UV, sulfuric acid rain and reverse alkali and fading after sewage penetration, large-scale production of pattern research and stability of each batch of color, coloring method, thickness and thinness After the introduction of American technology, we will study the method and construction scheme of each type of wall, find out the cause solution after the quality problem occurs, and complete the experiment and practice process. 2. What is art stone and art brick? Art stone is also called man-made culture stone. It is made of natural stone as the matrix, through artistic modeling, and by manually turning the mold, so it is called art stone. Artistic brick is similar to brick in volume and shape, and its surface is made of various textures. Including carving, relief surface, wood grain, stone grain, leather grain, cloth grain, etc. So it's called art brick. 3. What is archaize brick? Antique tiles are as like as two peas, which are made of ancient bricks. They are weathered by weathering and are not uniform. They are made of moulds and silicone rubbers from dozens of years, hundreds of years, and thousands of years. And then through the modulation of antique color to make the same material as the ancient brick, called antique brick. 2、 Is artificial culture and cultural brick environmentally friendly? The art stone and art brick of Wuhan Jiacheng huiran building materials Co., Ltd. are made of inorganic materials. The main materials are high-grade Portland cement and ceramsite (ceramsite is a kind of light thermal insulation material, which is made by firing shale), quartz sand and inorganic iron oxide color powder are made by mixing with clear water. It is a new environmental protection material promoted by the state, which is non-toxic gas and non radioactive. Jiacheng products have passed the national ISO quality system certification, and the quality reputation has passed the 4A level Chinese quality credit enterprise. 3、 Fading of artificial culture and cultural bricks There are many reasons for the fading problem: 1. It is caused by strong ultraviolet, long time of sunlight exposure and rain water washing. 2. The air quality is poor. When it rains, the dirty water on the roof is washed down by the rain. The culture stone is absorbed into the body and covered with color. 3. Solution: cultural stone is generally composed of base color and face color. The base color is the color of cultural stone itself. The face color is used to adjust the color difference and natural sense of cultural stone. The key lies in the production of color paste. The color paste must be thick, wear-resistant and high density. It must be waterproof and UV resistant. The product itself is not anti alkali, anti alkali will also eat the color. 4. To solve the problem of anti alkali: during the production of raw materials, add active resin and other related chemical raw materials, mainly steam and nourish the product after demoulding, and discharge the calcium in the product, so as to avoid anti alkali. After the product is put on the wall, a protective film is made to protect it against sulfuric acid rain, dirty water and ultraviolet rays.

Product advantages of natural cultural stone

　　Natural cultural stone is a stone deposit mined in nature. Slate, sandstone, and quartz stone are processed to become a decorative building material. Natural cultural stone is hard, bright in color, rich in texture and different in style. It is resistant to pressure , Wear resistance, fire resistance, cold resistance, corrosion resistance, low water absorption and other advantages. The main feature of 　　 natural culture stone is durable, not afraid of getting dirty, and can be scrubbed for unlimited times. However, the decorative effect is limited by the original texture of the stone. Except for the square stone, other constructions are more difficult, especially when splicing. The advantage of artificial culture stone is that you can create colors by yourself, even if you don’t like the colors when you buy them, you can also create colors by yourself.

Construction process of cultural stone

The construction of cultural stone is very different from ordinary wall construction. 　　 1. Clean the wall surface and make a rough surface. If it is a low-absorbent smooth surface such as plastic wood, it must be covered with iron wire and a rough bottom surface, and then pave it after sufficient maintenance. 　　 2. Before sticking the rocks, be sure to arrange the rocks on the flat ground to achieve a good effect, and then pave them in the order of arrangement. Do not put rocks of similar size, shape, and color next to each other. 3. White cement above No. 425, ordinary cement (the ratio of cement: sand: 801 glue is 1:2:0.05), ceramic bonding agent (please pay attention to the instructions for use of the bonding agent) high-performance special bonding agent can be used as glue. 4. Fully wet the rock, apply the adhesive at the center of the rock bottom to pile up in the shape of a mountain (a thin layer of adhesive can be applied to the bottom of the brick when pasting antique tiles) If you accidentally soil the surface on a large area, you need to use a brush in time Use after washing. 　　 5. Post the corner first. Press fully to make the adhesive squeeze out around the rock (some products do not need corners). 　　 6. If the construction needs, the rock can be cut to adjust. 　　 Seven. Fill the gap with plastic bags and pay attention to the depth. The deeper the gap, the better the three-dimensional effect of the product. 8. After initial setting of the caulking agent, remove the excess caulking material with bamboo chips, etc., and repair the crack surface with a wet brush. If there is a small amount of caulking agent or adhesive on the rock surface, let it dry After that, remove it with a brush. better. Some products do not require seams. 　　9. When the rock is used outdoors, after the paving is completed, the product and the caulk can be sprayed with a protective agent for protection (waterproof, antifreeze, anti-ultraviolet, anti-alkali, etc.) after the product and the caulking agent are completely dry. 　　10. Treatment of the requirements for remaining joints (1) Randomly shaped rocks-small joints with a circumference of about 10mm, the difference in the size of chaotic shapes should be adjusted with a caulking agent.
