Q:How to choose artificial marble
Natural stone has a certain amount of radioactivity, but the impact on the human body is not as exaggerated as imagined.Choose marble key to distinguish A, B, C three stone standard. According to the National Building Materials Bureau and the Ministry of Health jointly developed the building materials industry standards JC518-93Natural stone products radiation protection classification control standard "stipulated in the class a radiation is relatively small, the use of unrestricted; class B except not easy for the decorated rooms, available elsewhere; the C class is only available building decoration.In general, the radioactivity of dark marble is relatively high.
Q:Artificial stone is no pollution? Artificial stone and natural marble which radiation is more serious?
We can do a related test, in the family, now the wire, TV, computer monitor screen, mobile phone and so on, have certain radioactive, radioactive, are natural marble, the key is whether you buy the marble over standard. You need the marble in what place. In addition, if you want to control the amount of radiation, do not want to buy high radiation stone, should try to choose imported stone, because in the entry, the customs will be tested on imported stone, to see if the radiation is too high, if exceed the standard,
Q:Is marble good or man-made?
Natural marble is higher than artificial marble, and artificial marble may be more harmful than natural marble. If the conditions permit to ensure that the real thing, or choose a good natural marble. Please remember that regardless of the choice of natural marble or artificial marble, must be selected real material, and selected to the harm of the harm to the human body is still quite large.
Q:Limestone for producing calcium carbonate. Requirements of calcium carbonate content greater than 98%, above, what quality limestone?
You should be the content of calcium in calcium oxide, calcium oxide content of 55% is equivalent to the calcium carbonate content of 98.2%, plus you can go out a part of impurities in the process of burning, so you can fully meet the requirements.
Q:Marble how to maintain?
(1) marble is porous material, it is easy to stain. Clean water should be less. Regularly with a damp cloth wipe with mild detergent. Then dry and polish with a clean soft cloth.(2) serious wear of the marble furniture available to handle, steel wool wipe, and then use the electric polishing machine polishing. Make it dull. Or wipe with liquid detergent. Use lemon juice or vinegar to clean dirt, but should pay great attention to. Lemon stays at the best time not more than 1-2 minutes. Do not place the lemon for a long time to absorb the marble, if necessary, repeat operation. And then clean and dry.
Q:How is marble formed?
Also called marble marble, is formed by sedimentary rocks and sedimentary rocks of metamorphic rocks, usually accompanied by biological remains. The texture is mainly composed of calcite, limestone, serpentine and dolomite, its composition to calcium carbonate, accounting for more than 50%, and magnesium carbonate, calcium oxide, manganese oxide and two silicon oxide. The minerals are mainly calcite, hydrochloric acid occurred bubbles, changing crystal structure with grain or granule, particle size of a marble. Natural decorative stone is one of the main categories, generally refers to a decorative function, can be processed into building stone or crafts have metamorphism or non metamorphic carbonate raw marble. Produced in the Yunnan province of Dali white with black pattern of limestone profile can form a natural landscape painting, ancient times often select has a molded marble used for painting or screen The name of the marble mosaic, later gradually developed into a call all have various color patterns, used for building decoration materials limestone, commonly known as the white marble white marble, but on the translation of Western made of white marble statue called marble. Marble is the name of the commodity, is not defined. Petrology marble is a natural stone building decorated a gate. Class, generally refers to a decorative function, can be processed into building stone or crafts have metamorphism or non metamorphic carbonate rocks.
Q:Does black marble have radiation?
Do not know if you choose a class a marble, if it is a class, you can rest assured that living, but if not, not to say. National standard, class A is the use of residential environment, B class public space use.
Q:Marble surface polishing color becomes dark no light how to restore the original
The ground side evenly sprayed K2, K3 drops, while using marble polishing, cleaning machine with red scouring pad, K2, K3 with the same amount of water drops onto the ground, using 175 RPM wiping machine weight 45KG start grinding, the surface effect of heat the material formed in the crystal surface after the crystallization of stone surface.Add: the whole ground maintenance treatment: if the porosity is large (stone sandstone, travertine marble etc.) to door besmear, after 12 hours, and then washing machine alternately to complete K2, K3 drops mill on the ground, K2-K3-K2-K3-K2 a total of five times, and then put on the white polishing pad, spray a small amount of K1 the potion, RE polishing time, in order to increase the surface hardness of the ground.Ground cleaning maintenance: when the surface of the stone to form crystal mirror, use the vacuum cleaner to suck ground residue and water, and finally the use of polishing pad polishing, the surface is completely dry, bright as a mirror, if the local damage can be the local maintenance, construction completion can always walk on. Note that some of the use of long stone ground height error is larger, this is because of the foundation settlement and external damage caused by factors such as. These floors, such as the reference 2m + 1mm flatness standards, it is difficult to achieve, only through grinding, grinding the focus of the higher part, you can adjust and reduce the flatness error.
Q:What is the best brand
First, import artificial stone brand1, DuPont Corian2, Samsung star capacity3, South Korea LG4, Formica SelidstoneComment: DuPont and Samsung in the retail market is more common, with LG and Formica works, this brand is the representative of the high-end artificial stone.
Q:How to determine the compositional maturity and structural maturity of sandstones and their genetic significance
Gravel clastic sediments: rock conglomerate + quartzite gravel / other rock gravels;Clastic sediments of sand or silt: single crystal quartz / single crystal feldspar; single crystal quartz + flint cuttings;Mud clastic sediments: Al2O3 / Na2O (two chemical analysis results);Detrital composition maturity reflect geological clastic components through time and strength, they are affected by climate and tectonic conditions are largely restricted. Generally, immature sandstone is near provenance deposits, containing many unstable clastic rock debris, such as feldspar and mafic minerals. The high maturity of the sandstone is after a long distance transportation, products suffered transformation, almost all are composed of quartz sandstone types. Therefore, in the presence of debris and detrital minerals and relative abundance, namely composition maturity, is reflect the geological conditions, source area weathering degree and moving distance.Structural maturity refers to the extent to which the clastic material is close to the ultimate structural characteristics under the transformation of weathering, transport and sedimentation, and is usually expressed as the base content, the ratio of sand to mud or the ratio of the particles to the matrix
