What should I pay attention to when buying stone? How to choose a good stone

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.

Stone purchase skills.

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.

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

stoneIt is also the material we will use when decorating, whether it is when we decorate the cabinets, or when we decorate the window sill, we will use stone, and there are many types of stone on the market, so those stones are better? What are our skills for buying stone? If you don't know, let's introduce it to you!

First, which stone is better.

1.Artificial stone is beautiful and practical, it has the richest colors, and is wear-resistant; Acid; High temperature resistance; Impact-resistant! Stress resistant!

Resistant! It is also very resistant to permeation and other functions. Using the unique bonding and grinding technology, the artificial stone countertop can be seamlessly spliced, and there is no porosity on the surface, and there is no place for dirt and bacteria.

It is also radioactive and easier to clean, making it an ideal alternative to natural marble. However, the naturalness of artificial stone is obviously insufficient, the texture is relatively fake, ** is high, and the anti-scalding ability is not strong. Objects that are too hot will fade when put on them, and scratches are easy to appear if the hardness is not enough.

2.Natural stone refers to the quarried from natural rock mass, which has high compressive strength, wear resistance and durability. Due to the fine pores on its surface, it is weak in terms of stain resistance.

Although the merchant will treat its surface in terms of color and luster when it leaves the factory, it will reveal its true face after about half a year to a year of use. In interior decoration, marble is suitable for TV countertops, window sills, indoor floors, etc. Thresholds, countertops, and outdoor floors are suitable for granite.

3.Its quartz stone is manufactured under vacuum conditions, such as the inside and outside.

1. Dense and non-porous composite materials, the quartz surface has excellent corrosion resistance to the acid and alkali of the kitchen, and the liquid substances used daily will not penetrate its interior, and the liquid placed on the surface for a long time only needs to be wiped with a rag with clean water or clean and bright detergents, and the retained objects on the surface can be scraped off with a blade if necessary.

Second, how to choose a good stone.

1.That is, to observe the surface structure of the stone with the naked eye. Generally speaking, the stone with uniform fine material structure has a delicate texture and is a good product for stone; The appearance effect of coarse-grained and unequal grain structure of stone is poor, the mechanical and mechanical properties are uneven, and the quality is slightly poor.

In addition, due to the influence of geological action, natural stone often produces some fine veins and micro-cracks, and the stone is most likely to crack along these parts, so attention should be paid to reject. As for the lack of edges and corners, it affects the appearance, and you should pay special attention to it when choosing.

2.Listen, that is, listen to the sound of the stone tapping. Generally speaking, the stone with dense and uniform interior and no microscopic cracks has a crisp and pleasant percussion sound; On the contrary, if there are microscopic cracks or veins inside the stone, or if the contact between particles becomes loose due to weathering, the percussion sound is coarse.

Well, the above has an article on how to buy a good stone and which stone is better, it is introduced here, if you want to buy a good stone, then you must understand before buying, so that you can buy a good stone, I hope this article can help you.

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.

The best quality of stone directly affects the decorative effect, and the stone selected in different areas should also be different, so how to choose stone? It is understood that there are many kinds of stone on the market, and the products are uneven, so we should grasp three points in the selection of stone.

First of all, the surface of the stone should have a uniform fine material structure, with a delicate texture, the general high-quality stone does not contain too much variegation, uniform cloth color, smooth surface, high brightness, and the appearance of the coarse-grained and unequal structure of the stone is poor, and the quality is slightly worse. Also due to the influence of geological action, natural stone often produces some fine pulsations and micro-cracks in it, and the stone is most likely to crack along these parts, lacking edges and corners, so you should pay attention to it when buying.

When buying, you can listen to the knocking sound of the stone, the general stone knocking sound is crisp and pleasant, if there are slight cracks inside the stone or the contact between the particles becomes loose due to weathering, the knocking sound is rough and hoarse, which indicates that the quality of the stone is not good. When purchasing, it is also necessary to measure the size and specifications of the stone, so as not to affect the splicing, or cause the pattern, pattern and line deformation after splicing, and affect the decorative effect.

Finally, when buying stone, the dealer should be required to have a radioactive certificate, try to choose class A products, and marble and granite should be considered first, because under normal circumstances, the radioactivity of granite is greater than that of marble.

The types of stone used in different areas are also different. The TV background wall is the main area of stone decoration, and you can choose granite to do personalized modeling design, and you can also decorate the wall surface such as the entrance. For window sills and balconies, you can choose marble, which is required to be non-slip and wear-resistant, and try to choose brand products with better quality.

As far as the stone laying ground is concerned, it is more appropriate to choose marble, the living room can choose artificial stone with good high temperature resistance, and the bathroom can choose non-slip type of stone, which must be moisture-proof, acid-proof, alkali-proof, high-temperature resistant and other properties. Also because of the high patchwork of stone, the decorative performance in the bathroom is more prominent, so the stone is used more in the bathroom.

Don't be fooled, China's stone industry is informal

In home decoration, stone is widely used, such as: bay window countertops, pass stones, decorative walls, bathroom countertops, cabinet countertops, etc. However, stone as a high-grade decorative material, its own some harmful radioactive substances will cause damage to the human body, so in the decoration of what kind of stone can not only beautify the effect of the room but will not affect the health of the family, today I will teach you how to choose decorative stone.

1. Observe the surface structure of the stone

The quality of natural stone depends on the quality of the blocks and the processing technology. The surface of high-quality stone does not contain too much variegation, the cloth color is uniform, and there is no fainting and thickening, and the quality of the stone will be a lot of unbridgeable after processing. Usually, the uniform fine structure stone has a delicate texture and is the best product of stone; The appearance effect of coarse-grained and unequal grain structure of stone is poor, the mechanical and mechanical properties are uneven, and the quality is slightly poor.

In addition, due to the geological influence, natural stone often produces some subtle cracks in it, which is easy to cause stone cracking, and should be removed.

Second, understand the quality of stone

The material of the stone should be uniform and complete, and problems such as dark cracks, black scars and color differences should be avoided.

1.Pay attention to the composition of the stone, and avoid containing excessive amounts of harmful substances such as iron sulfide, iron oxide, carbonaceous and clay;

2.Pay attention to the radiation level of the stone;

3.Pay attention to whether the stone contains excessive mineral components with high coefficient of thermal expansion, thermal conductivity and electrical conductivity to avoid the danger of cracking, thermal conductivity and electrical conductivity.

3. Understand the durability of stone

Stone with uniform pore distribution, small pore size, low water absorption, high hardness and compressive strength should be selected as much as possible. However, it should be noted that although the strength of stone with large gravity is higher, it will increase the load of the structure and reduce the strength and seismic resistance of the house.

Fourth, measure the size and specifications of the stone

The reason why the size and specifications of the stone should be measured is to avoid affecting the splicing, or causing the deformation of patterns, patterns and lines after splicing and affecting the decoration effect. In terms of plate specifications, the ground should be as much as possible to choose granite sheets (8 12 mm), which is mainly based on the strength of the ground and the load-bearing of the house.

5. Knock on the stone and listen to the sound

Generally speaking, the stone with dense and uniform interior and no microscopic cracks has a crisp and pleasant percussion sound; Conversely, if there are microscopic cracks or veins inside the stone or if the contact between the particles becomes loose due to weathering, the knocking sound will mark the glue coarsely.

Sixth, use simple testing methods to test the quality of stone

A small drop of ink on the ground on the back of the stone, if the ink can be quickly dispersed and leached, it means that the internal particles of the stone are loose or there are microscopic cracks, and the quality of the stone is not good; On the contrary, if the ink drips in place, it means that the stone is dense and the place is good.

Generally, the stove bai table is made of natural marble, such as black du golden sand. Black diamonds, blue diamonds, these granite materials are hard. Not easily impermeable.

Internal oil stains. It is also beautiful and generous, and the capacity is very high-grade. **Also moderate. There is also a medium quartz stone is also very popular. But the quality of quartz stone workmanship market Cen is not even, need to know how to change, what do you don't understand, you can consult me, we are specialized in home decoration stone 18059111256Impression hardcover stone.

01) The brighter the surface, the harder the texture.

When we pick marble in the stone yard, we all see a large piece of stone like this.

The stone is arranged according to the color system and type, and the integrity of the texture should be considered when selecting, and the more detailed the grain is, the better the quality.

Then take a closer look at the surface gloss, the polished surface of the marble can produce a mirror-like reflection.

The brighter the mirror effect, the harder the stone, the higher the structural density, and the better the quality.

02 ) Tap the marble, the crisper the sound, the better.

You can knock on the stone with coins or other items, and the sound is crisper, indicating that the hardness is high, the internal density is also higher, and the quality of the stone is better.

If the sound is muffled, it means that the hardness is low or there are internal cracks, and the quality is poor.

03) Confirm the surface for cracks or bruises.

Marble is a natural product, and there will inevitably be defects on the surface, and some holes are acceptable, which can be repaired by polishing and filling.

However, pay special attention to whether the marble surface is cracked or bruised.

Although marble has high hardness, it is brittle, and if there are cracks, it is not easy to re-process, which also increases the difficulty of construction, and may produce larger cracks in the process, or even a whole piece of fracture.

04 ) Confirm the water absorption rate with drip ink.

Ink drops on the surface or side of the marble can detect the density structure of the stone, the higher the density, the less likely it is to absorb water, and the denser the marble texture.

In addition to testing the quality of stone through the above methods, there are also tips to pay attention to in the selection according to the different areas used, for example, marble is used on the floor, dark colors are better than light colors.

Marble itself has capillaries, pores are many, easy to get stuck in dirt, if you want to use marble to lay the ground, it is recommended that dark marble is better than light color, relatively resistant to dirt.
