What is full-body marble
Date of issue:2021-07-15 Reading volume:163
There are many types of marble materials, and many people are particularly entangled when choosing them, and don't know how to consider them. If you have troubles in this regard, you can learn more about what is a full-body marble and how to identify marbles, and find the skills to choose, then you can still have a very good help in the future. In addition, no matter which materials you choose, you should analyze which ones are likely to meet your expectations, and don't blindly follow the trend.
 
What is full-body marble
 
  The whole body marble is important in the type of rock, the main component is calcium carbonate, there are many different formation reasons, and there are many characteristics.
 
   Limestone softens under high temperature and pressure, and recrystallizes to form marble when the minerals contained in it change. The main components are calcium and dolomite, with many colors, usually with obvious patterns and many mineral particles. The Mohs hardness is between 2.5 and 5. Because marble generally contains impurities, and calcium carbonate is easily weathered and corroded by carbon dioxide, carbides, and moisture in the atmosphere, and the surface quickly loses its luster.
 
Features of whole body marble:
 
1. No deformation
 
   The rock has been natural aging for a long time, the structure is uniform, the linear expansion coefficient is very small, the internal stress disappears completely, and it is not deformed.
 
2. High hardness
 
   Good rigidity, high hardness, strong abrasion resistance, low temperature deformation.
 
3. Long service life
 
   No need to apply oil, not easy to stick to dust, easy and simple maintenance, and long service life.
 
   There will be no scratches, and it is not blocked by constant temperature conditions, and it can maintain its original physical properties at room temperature.
 
4. Not magnetized
 
  It can move smoothly during measurement, without a sense of stagnation, and is not affected by moisture. The plane is weighed well. Physical properties: specific gravity 2970-3070kg/m3; compressive strength: 2500-2600kg/cm2; coefficient of elasticity: 1.3-1.5×106kg/cm2 water absorption.
