Question 1: Can marble be used for outdoor projects? Generally speaking, marble is not suitable for outdoor use. Special varieties or used in special parts can be used, such as white marble railings (commonly known as white marble).
Reasons:
1. The texture of marble is relatively soft, and it is easy to wear when used for floors, etc., and it is easy to knock corners when used for steps;
2. Marble is generally It contains impurities, and its main component, calcium carbonate, is easily weathered and corroded by carbon dioxide, water vapor, etc. in the air.
Question 2: What kind of stones can be used outdoors? Marble and granite are all stones used for outdoor decoration. Secondly, there are various cultural stones, cobblestones, etc.
Question 3: Why is marble not used for outdoor decoration? Marble is more common indoors and rarely used outdoors. Granite is widely used outdoors!
Marble is a metamorphic rock formed by the high temperature and high pressure in the earth's crust. Mainly composed of calcite, limestone, serpentine and dolomite, it is generally softer than granite. Marble containing chemically unstable red, dark red or golden particles with smooth surface will loosen the structure of the marble and produce qualitative changes under the action of sunlight. In addition, marble generally contains impurities, the main component of which is calcium carbonate. It is easily eroded by carbon dioxide, sulfide, water vapor, etc. in the atmosphere, loses surface luster, weathers, and cracks. Therefore, except for a few, such as white marble and moxa leaf green marble, marble generally contains impurities. The relatively stable and durable varieties with pure quality and few impurities can be used outdoors, while other varieties are not suitable for outdoor use and are generally only used for indoor decoration.
Question 4: What standard stipulates that marble stone cannot be used outdoors? Natural marble is divided into two types according to its composition, carbonate and granite. Granite is used outdoors, such as Indian red and Chinese red. Gray hemp, blue hemp, etc., the chemical properties of SIO2 are stable. The main component of carbonate rocks is CaCo3, which is chemically acid-phobic and reacts with acid rain. Not suitable for outdoor use, such as gold thread beige, brown mesh, white marble, etc.! If it is to be used outdoors, a protective layer must be applied, such as waxing, etc.!
Question 5: What are the different treatments for marble and granite used indoors and outdoors? Granite: Granite stone has no colored stripes, most of them only have colored spots, and some are solid colors. The rock is hard and dense, has high hardness, is wear-resistant, and is not easily weathered or deteriorated. Its appearance and color can be maintained for more than a hundred years, so it is often used in high-end building decoration. Engineering, in home decoration, it is more suitable for outdoor balconies, courtyards, guest restaurant floors and window sills. Granite is generally used on exterior walls. After you decorate the granite, it needs to be crystallized and cured. This will protect the granite from being damaged by external pollutants as little as possible. You can set a certain period of time to give it regular treatment. It is crystallized and cured, so that it can maintain its brightness and texture. Generally, if our company does it, it can extend its durability.
Marble: Marble has simple mineral composition and is easy to process. Most of them have fine texture and good mirror effect. Its disadvantage is that its texture is softer than granite, so it is easily damaged when hit by hard and heavy objects, and light-colored stone is easily contaminated. Since marble generally contains impurities, and calcium carbonate is affected by carbon dioxide, carbides, and water vapor in the atmosphere, it is also easily weathered and corroded, causing the surface to quickly lose its luster. Therefore, most marble varieties are not suitable for outdoor use and are generally only used for indoor decorative surfaces. We have to deal with it according to its different symptoms. Generally used for renovation and crystallization maintenance
Determination of stone disease:
Stone disease is caused by many reasons. According to the pollution source, it is divided into rust yellow, plant color pollution, chemical pigment and colloid pollution. , various oil pollution, alkaline return, etc.
Stone protection:
Stone protection uses a special stone protective agent to fully penetrate into the interior of the stone and form a protective layer (water-blocking layer), thereby achieving waterproofing and anti-fouling , acid and alkali resistance, anti-aging, anti-freezing and thawing, anti-bioerosion and other functions, thereby improving the service life and decorative effect of the stone. Stone protection treatment can extend the life of the stone. Generally, it should be redone every 2 years for the best effect.
Performance characteristics of stone protection:
1. After protective treatment, the protective agent penetrates into the interior of the stone to form a deep protective layer to protect the stone from pollution and prevent rust spots. The surface of the stone will be anti-fouling and waterproof. Even if it is contaminated, the dirt will only float on the surface, making it easy to clean.
2. There will be no color change on the surface of the stone and no falling off.
3. The shrinkage rate is significantly reduced, which can prevent the stone from cracking at low temperatures (-10℃--45℃).
4. It can prevent natural weathering, salt water corrosion and other phenomena of stone, reducing the impact of climate on stone. Compared with ordinary stone, the service life of stone after protective treatment is doubled. .
5. The protective agent will not cause damage to the stone surface, and will make the stone highly breathable, will not weather or oxidize, and will increase the gloss.
6. Using special protective agents, you can also achieve the effect of enhancing or deepening the color of the stone.
Stone cleaning:
Under the influence of the outside world, the quality, performance, color and other aspects of stone will be affected, and the decorative effect will also be reduced. The reason is that harmful ion solutions can freely enter and exit through the pores of the stone. In this process, water becomes the carrier of these harmful substances and the main role in participating in the chemical reactions of harmful substances. Generally, physical or chemical removal is used to repair stone diseases and restore the stone. 's original appearance.
Several common stone diseases:
Rusty yellow spots, organic stains, white flowers (alkali return), freeze-thaw, water spots and wet marks, chemical corrosion, oil spots and oil stains The spots are dull, powdery, peeling off, holes, cuts, hollows, and cracks.
Question 6: Why is marble not suitable for outdoor floor paving? Marble is easily crushed by vehicles outdoors.
Question 7: Can natural marble be placed on an outdoor balcony? Natural marble is not recommended to be placed outdoors. Generally, natural marble is used indoors, and granite stone can be used outdoors
Natural marble is an original material in the earth's crust. Metamorphic rock formed by the action of high temperature and high pressure in the earth's crust. It is a medium-hard stone, mainly composed of calcite, limestone, serpentine and dolomite. Its main component is calcium carbonate, accounting for more than 50%. Others include magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. Since marble generally contains impurities, and calcium carbonate is affected by carbon dioxide, carbides, and water vapor in the atmosphere, it is also easily weathered and corroded, causing the surface to quickly lose its luster. Therefore, a small number of relatively stable and durable varieties with pure quality and few impurities, such as white marble and mugwort, can be used outdoors. Other varieties are not suitable for outdoor use and are generally only used for indoor decorative surfaces. Nowadays, traces of him can be seen on marble TV background walls, marble floor mosaics, and stone stair steps in almost every household.
