Q:Characteristics of white hemp granite

Excellent quality, high surface finish, corrosion-resistant acid and alkali, hardness density, iron content is very low, no radioactive, and the United States white linen, a gray background color, color is more uniform. Stone Category: Granite (Granite), commonly known as Chinese white linen, sesame white, national standard Code: G3765 granite Stone features: excellent quality, high surface finish, corrosion-resistant acid and alkali, hardness density, iron content is very low, no radioactive, and the United States white linen, a gray background, color is more uniform. Uses: suitable for external wall hanging, the ground plate and cylindrical processing, is in the high-end green building materials.

Q:What are the types of granite

Electrical granite colors are varied, except for colorless and white, which is extremely rare. This granite type is ideal where there is not much traffic because it is all types of soft. Note: When selecting granite, it is best to distinguish between materials by some companies according to the color of the granite classification. The type of granite divided in this way may have more than 100 kinds of granite.

Q:Are stones belonging to granite or marble?

Marble texture, the majority of fine texture, mirror effect is better. The disadvantage is the texture of the granite than the soft, heavy objects hit the vulnerable vulnerable, more for indoor use.

Q:How is the granite floor refurbished and maintained?

First, the renovation of the granite ground needs to refurbish the speed and weight of the machine, grinding the marble refurbished machine can also but the effect and 260 kilograms of granite grinding machine can not be compared!

Q:Does the smooth granite need to be waterproof?

If you do not do it, it affects the appearance of the effect and life. According to my experience in several projects stone construction, it is best to do six-sided protection, protective agent is best oily, matte, colorless.

Q:What is the hardness range of granite?

The granite has a specific gravity of between 2.63 and 2.75 and has a compressive strength of 1,050 to 14,000 kg / cm2 (15,000 to 20,000 pounds per square inch) because the strength of the granite is greater than that of sandstone, limestone and marble. Granite formation of the special conditions and firm structural characteristics, it has the following unique performance: (1) has a good decorative performance, applicable to public places and outdoor decoration. (2) with excellent processing performance: saw, cut, polished, drilling, sculpture, etc. Its processing accuracy of up to 0.5μm below the luminosity of more than 1600. (3) wear resistance is good, 5-10 times higher than cast iron. (4) thermal expansion coefficient is small, not easy to deformation, and indium steel is similar to the temperature affected by minimal. (5) elastic modulus, higher than cast iron. (6) Rigid, internal damping coefficient, 15 times larger than steel. Can shock, shock. (7) granite with brittle, damaged only partial loss, does not affect the overall straightness. (8) granite chemical stability, not easy weathering, acid, alkali and corrosive gas erosion, the chemical and silica content is proportional to the service life of up to 200 years. (9) granite with non-conductive, non-magnetic, field stability.

Q:How much money is a cubic meter of granite

The final account of both parties will agree on the price of granite stone, but I now make the budget, only the general offer is not bad on the line, but not too much, so want to master for help.

Q:Is the granite floor harmful to the human body?

Red granite, potassium-containing mineral K-feldspar is the main component of red granite, and potassium isotope potassium-40 (40K) itself is a radioactive element. So the more potassium-containing minerals (pale pink, pink, etc.), the more likely to be strong (large). In addition, in the red granite, including gneissic granite and granite gneiss. This ancient rock, which was produced two or three billion years ago, contains not only potassium-containing feldspars, but sometimes also contains a beautiful color (purple, red, purple, etc.) special minerals - zircon (Zr A Sio4). Zircon mineral is often mixed with uranium, thorium and other radioactive elements, so that the red granite red more brilliant at the same time, then also increased the intensity of the radio, which is the famous "Indian red" and "South Africa red" roll intensity is too large (High) the reason.

Q:What is the effect of granite tiles in the room?

Stone radioactive on the human body there are two kinds of harm, one is the stone radionuclide decay release X-ray, causing external exposure to the human body, but the probability of occurrence is very low; the other is the release of radon caused by internal exposure to the human body The Radon is the decay product of radioactive uranium, radium and thorium in the crust, radon is classified as one of 19 carcinogens, mainly induced by lung cancer. According to the test, different colors of the stone is also different radioactivity. The highest is red and green, white, black is the lowest. Therefore, consumers should carefully choose the red, green or with a large spot of red granite varieties. He said that granite should not be used in large quantities indoors, especially in the bedroom, children's room to use.

Q:What is the globular weathering of granite and why is it a "globular" strange name?

Spheroidal weathering (spheroidal weathering): the rock was spherical, from the table and the layers of weathering peeling phenomenon. It mainly occurs in granite, diabase and some sandstone. Fracture cutting in different directions, rock, water, gas and various microbial invasion along the cracks, resulting from the table and the layers of weathering peeling. As the surface area of the rock mass is larger, the strength and depth of the weathering are relatively large, so that the part of the rock mass is not subject to weathering. After the ball-like weathering debris material is stripped, the residual spherical rock block is called "stone egg".
