Q:pelitic siltstone

Sandstone (Sandstone) - a rock formed by the consolidation of sand and sediment through the water and deposited on the bed of the river for thousands of years. The sandstone structure is granular, the permeability is good, the sand particle size is 1/16-2mm, the particle is specially small, for example in the diameter 1/16-1/250mm is called the siltstone. The main components are: more than 52% of quartz composition; clay around 15%; goethite about 18%; other substances more than 10%. If the quartz content is above 90%, it is called quartz sandstone.

This time there should be no radiation.When you want to buy stones must be clear stone radioactive and harmful gas indicators, when used to maintain indoor ventilation. Only open the window ventilation, reduce harm. Put some plants, the air is also helpful to the fresh point, we should pay attention to the selection of suitable for indoor cultivation.

Q:How many tons of limestone does each produce ten thousand tons of cement?

Cement by limestone, clay, iron ore powder mixed in proportion, at this time the mixture called raw materials. And then the calcination, the general temperature of about 1450 degrees, the calcined product called clinker. The clinker and gypsum are then ground together in a mixture, which is called cement. At this time the cement called ordinary Portland cement.

Q:Marble platform should pay attention to what matters

Matters needing attention：1, do not knock, collision marble platform;2, do not put other items on the marble platform;3, the position of the mobile marble platform, the need to re adjust the level;4, the marble platform to choose a small noise, dust, no vibration, temperature stability environment.

Q:Limestone and dilute hydrochloric acid can not make clear lime water becomes muddy, why

Limestone and dilute hydrochloric acid reaction is the production of CO2, and then into the Ca (OH) 2, so that the clarification of lime water turbidity, the formation of CaCO3 precipitation (turbidity). The condition is in the alkaline solution; and can not make clear the water becomes muddy, that is, the solution is acidic will also generate precipitation, can dissolve the reason.

Q:Artificial stone countertops or natural marble countertops good?

Artificial stone：(1) advantages: artificial stone is more wear-resistant, acid resistance, high temperature resistance, impact resistance, compression, bending, anti permeability and other functions are also very strong. Its deformation, bonding, turning and other parts of the treatment of unique; colorful, the overall shape, and can be repeatedly polished renovation. Therefore, pollution resistant, because the surface is not porous, oil, water stains difficult to penetrate them, general stains can be wiped with a damp cloth or detergent; seamless bonding can be any length, with adhesive material grinding, two pieces of adhesive joints without trace all blend into one harmonious whole.(2) disadvantages: the nature is obviously insufficient, the texture is relatively false; the price is higher, even if it is a seamless artificial stone can not withstand the sharp metal, such as". And because of the different processing technology, the quality is also divided into various grades and ranks, so the choice must pick a better reputation, service assurance brand.
