Introduce what problems natural stone should be paid attention to when purchasing

granite and marble.

1. When it comes to stone, people are most concerned about the radioactivity of stone. In fact, any substance in the world is radioactive, but some radiation does not cause harm to the human body. The radioactivity of stone used in small area home decoration generally does not cause damage to the human body;

2. In contrast: the radioactivity of granite is greater than that of marble, and the "Mongolian black, Chinese black, and Jinan green" we commonly use belong to granite, but they are all relatively "safe" stones, although we can use them with confidence;

3. The most commonly used natural stone for home decoration is mainly black, and the varieties are Jinan green, Chinese black and Mongolian black are the most common, especially Mongolian black. Some people's windowsills, bathroom countertops, and shower retaining strips are all Mongolian black;

4.Before buying stone, the way to distinguish whether it is dyed is: look at the section and the bottom surface, the dyed stone is black as a whole because it has been soaked, and under normal circumstances, the cut surface and the bottom surface are white and gray.

Natural stone is commonly used in locations such as window sills, such as bathroom cabinets, the aforementioned shower retaining strips, and some owner's cabinets are also made of natural stone.

Some experience with stone:

1) The radiation of most of the stone on the market will not pose a hazard to the human body, and the amount of home decoration itself is not large, although it can be used with confidence;

2) Generally speaking, the darker the color of the stone, the stronger the radiation, but it does not refer to the "Mongolian black", "Chinese black" and other types of stone, mainly for the red stone;

3) Rhododendron red is a stone with serious radiation in the stone market, which should be carefully chosen;

4) For owners of natural stone for the preparation of cabinet countertops, it should be emphasized here that granite, not marble, should be used. Because the hardness of marble is lower than that of granite, it is easy to break when chopping vegetables and meat on the marble operating table in the future;

5) Stone is widely used abroad. Among the imported stones, the quality of Shaanna beige is very good, but it is expensive;

6) The same is a crack, for granite is an accident, for marble can be treated by using marble glue to fill the caulk and then use special sandpaper to polish it;

7) The greater the color difference of the marble with rich color and clear texture, the greater the difference in texture, the greater the difference in its components, and the greater the difference in its physical properties, the conclusion is: the more likely it is to crack and fracture. The black and white marble is especially noticeable.

1) Observation. Observe the surface structure of the stone with the naked eye, the uniform fine material structure of the stone has a delicate texture, which is the best product of the stone, and the appearance quality of the coarse and unequal structure of the stone is poor.

2) Listen to the sound.

Listen to the sound of stone knocking Dense and solid stone has a crisp and pleasant sound, and if there are cracks inside, the sound is rough and hoarse.

3) Measure the size.

Measure the size and specifications of the stone The stone with better quality has small size error, less warpage and smooth surface.

Fourth, the quality of the test.

Use ink to test the quality, drop a drop of ink on the back of the stone, if it is quickly dispersed and leached, it means that the quality of the stone is not good, on the contrary, if the ink does not move in place, it means that the stone is dense and has a good texture.

Fifth, according to the color of the purchase.

Generally speaking, red symbolizes auspiciousness and beauty, yellow symbolizes light and nobility, green symbolizes hope and tranquility, black symbolizes power and dignity, and so on. Colors carry people's hopes and wishes, showing people's different aesthetics and psychological expectations.

6. Purchase according to your budget.

For the average family, choosing domestic stone can also achieve a good decorative effect. Domestic stone such as black and white root, silver white dragon, silver gray dragon, kaphoya, melintekin, California beige, Fujian granite stone, bluestone, basalt, shrimp red rust stone, hemp, tiger skin white and other varieties also have strong decoration, and even some are better than imported similar products, but ** is much cheaper.

7. Pay attention to quality indicators.

The use area of stone in home decoration is generally small, and the radioactivity of stone will not cause damage to the human body, but in order to rest assured, when buying stone, you should see if there is a safety license for radioactivity, and choose according to the radiation level of the stone.

When choosing natural ingredients, especially natural stones such as marble, we should pay attention to avoid a certain amount of radiation, as well as the maintenance of the ingredients themselves.

1) Choose the right color and pattern. When you select a color, you can ask the merchant to provide a sample, and check the goods against the sample when picking up the goods, and require the color difference and small patterns to be roughly the same or similar. (2) Pay attention to the reflectivity of the stone.

The reflectivity of high-quality facing stone should be above 95%, consumers can use glass mirrors as a reference, the reflectivity of the mirror is 100%, and the reflectivity of first-class stone floors is 75% 95%. (3) Pay attention to the processing accuracy of the stone floor. Natural stone flooring is machine-sawed, planed or ground and cut.

The finely processed stone should be neat and consistent. Such a stone floor can guarantee the quality of laying. In order to eliminate irregularities, consumers can stack the surface of two stone floors to see whether the specifications around the stone floor are consistent, whether the surface is flat, and whether there are defects such as warping and depression.

In addition, it should also be noted that the surface of the stone floor has defects such as sand holes, cracks, stains and stains, and the above defects are not allowed for high-quality products.

The selection of pro-natural stone should follow the following principles: the first point. Economical.

If conditions permit, try to use local materials to shorten the transportation distance, reduce labor intensity and reduce costs. The second point. Strength & Performance.

The strength of stone is closely related to its durability, wear resistance, impact resistance and other properties. Therefore, according to the importance of the building and the environment in which the building is located, stone with sufficient strength should be selected to ensure the durability of the building. In addition, there have been recent foreign composite plate products combining stone and plastic or aluminum, that is, the back of the marble sheet is bonded with foam polyester or aluminum honeycomb structural materials and glass fiber cotton felt and other materials to form a composite plate with light weight, high strength, and thermal insulation characteristics.

The third point. Decorative. The stone used for the finishing of the building must consider the harmony between its color and natural texture and the surrounding environment of the building, and fully reflect the artistic beauty of the building.

At present, the natural rock veneer used in countries around the world is generally based on the standard thickness of 20 mm, but some Western countries have also produced some natural stone slabs with a thickness of 12 mm and 15 mm because of the decorative effect of using stone in some buildings. At the same time, in some countries and regions with developed stone processing industry, in order to adapt to the decorative effect of high-rise buildings, they pay great attention to the standard requirements of building materials, so they have launched ultra-thin facing slate with a thickness of only 8 mm, 10 mm and 11 mm, which makes the building finish appear particularly beautiful after polishing and polishing, and also saves a lot of raw materials.

Do you have any other questions that you need to consult?

Everyone should know that a lot of decoration materials will be used in decoration, especially after decoration, many materials will be used in decoration, such as wood, tiles and stone. When it comes to stone, many people should have used stone for decoration, especiallynatural stoneNow many people are using it, natural stone is the stone mined from the naturally formed rock, which is a very good decorative material. Let's take a look at the types of natural stone and the precautions when decorating.

First, the type of natural stone.

1. Sandstone. Sandstone is a sedimentary rock that is coarse and loose and deformed if it is wet. However, because its roughness is similar to the roughness of the mountains, it is often used as a decoration for walls.

2. Slate. The morphology of slate is generally tabular and is a rock without crystallization that has undergone metamorphism, and this rock can be cut into very thin sheets. The color of the slate varies according to the impurities it contains, it will be red if it contains iron, and black if it is carbon.

Slate can be used to make many decorative materials, such as roof tiles.

3. Granite.

Granite is a magmatic rock, which is formed by the weathering of rocks on the ground and then slowly moving towards the center of the earth, and melting at high temperatures. Because the density of the magma is lower than that of the surrounding rocks, it is gradually moved upwards to form new igneous rocks.

4. Marble.

Marble is a carbonate type of metamorphic rock that is itself limestone from the seabed, which has been precipitated for a long time to become limestone. When exposed to high temperature and high pressure underground, it changes and hardens, forming the current marble. Its texture contains different impurities when it is generated, so it can form a very beautiful texture, and marble can generally be used for more than 150 years.

Second, the decoration of natural stone precautions.

1. Pay attention to the treatment of the grassroots.

The base layer should be treated very cleanly, there can be no uneven places, and it must be kept clean and tidy, and there can be no mortar or oil stains and other items, and it should be soaked with water.

2. Pay attention to the paving of stone.

When paving stone and tiles, it is necessary to install the standard to carry out the construction, and the standard should be placed at the intersection of the reticles, and then the diagonal installation should be carried out.

3. Soak it.

When paving the stone, it is necessary to pave according to the line prepared in advance, soak the stone in water before paving, and wipe the back clean after drying.

4. Pay attention to maintenance.

After the installation of the stone floor, it is necessary to pay attention to the maintenance work, and sprinkle water on the ground one day after the installation, so that the water can slowly penetrate into the stone.

5. Tests should be carried out.

Before the decoration, it is necessary to test the paving, and after being able to completely dock the color and pattern, and then raise the spine for installation, it should be noted that there is a shell and hollow drum in the installation. Do not step on it within two or three days after installation, and pay attention to protecting the construction ground.

What should be paid attention to in the selection of natural stone in outdoor decoration projects as follows: the choice of stone should be consistent with your economic strength, and then the adaptability of the stone color. Each decoration style has an overall color matching, and it is not that the more expensive the stone, the more suitable.

It is the attribute of the stone variety itself. The natural properties of stone have the time to open the tung burning, which determines that it can not be made of the ground, or can not be wet pasted, or the subsequent use of sequelae (some design and trial parties do not consider this problem), I hope mine can help you <>

Do you have any other questions?

Stone non: natural (granite, marble); Artificial stone (artificial marble, resin artificial stone, cement artificial stone).

Purchase note: 1. View, the surface has a delicate texture of stone, no missing corners, cracks, color spots, and no too much color difference.

2. The quantity, the size deviation is less than 1mm, the thickness deviation is less than, the flatness is less than, the angle difference is less than 3, listen to it, the knock sound is crisp, and it proves that there is no crack inside.

4. Try, the back of the stone is dripping ink, and the ink is not moving to prove that it is dense.

5. Look, radiological test documents, a, b, c belong to that category.

6. With, invoice (with name, specification, grade, quantity) with warranty terms.

It depends on whether the manufacturer has a conscience, and the poor one is a good one to sell, and it is difficult to see that the stone slabs are divided into grades of pennies and pennies, and in the same kind of ** compare the product quality of each manufacturer, you can go to the local stone city to see the quality of the plate at the same time to ask**, who is good to find if the service is about the same. Some small orders of dozens of square meters forget about the stone This kind of thing is dusty and more money will not do it if you.

We have a large order of 10,000 square meters, for the sake of the silver ticket, my brother will help you to select goods on the spot of large manufacturers, of course, regardless of the region, I can help you.

Suppose you want blocks.

In terms of cost, it is best to go directly to the manufacturer with a mine to get the goods.

If you want a large board, it is best to go directly to the manufacturer to get the goods. The selection of manufacturers depends on whether they have various qualifications. For example, ISO, GB, CISE and other standards. If you are in the southwest area, it is recommended to go to Yunnan Red Stone Factory.

Look at the density, drop a drop of water, the fast diffusion is not good, and the slow diffusion is fine.

To select high-quality, high-quality stone, certain principles need to be followed as follows:

1. Follow the principle of economy.

If conditions permit, it is best to choose local materials, which can greatly shorten the transportation distance, reduce labor intensity, and achieve the purpose of reducing costs.

2. Pay attention to check the strength and performance of the stone.

The strength and performance of stone are closely related and very important. According to the importance of the building and the environment in which the building is located, the stone material that meets the requirements should be selected to ensure the longevity of the building.

3. The stone should have a certain degree of decoration.

The natural stone used for the decorative surface of the building must consider the coordination between the color and natural texture of the natural stone and the surrounding environment of the building, so as to bring out the artistic beauty of the building.

How the economy of stone determines whether people are affordable and cost-effective when buying stone, and the strength and performance of stone determine the quality of stone, and the decoration affects the beauty of stone. Therefore, people will be economical and affordable to choose stone in the case of following the above principles.
