Perlite stone is a natural mineral and a silica volcanic stone. The stone becomes a stone -like structure by removing the gas from the volcanic crater and being located against the dumb air. That is why it is known as volcanic glass. The most important feature of perlite stone is high resistance to heat and humidity. Buying and selling perlite is one of the most important topics in this article as well
What is a perlite stone?
Perlite volcanic stone consists of aluminum silicate and has very high water content. Because it has a magma and is formed with the hydration of ecidine. The formation of this stone is natural and its special feature is its formation and expansion as a result of overheating. The structure of this stone is layered and is a volcanic glass. Although the details of the discovery of this stone are unclear, it was first introduced in the third century AD as one of the silicone stones obtained from volcanic lava.
Properties of perlite stone
Perlite is a thermal insulation and reflects because it has a lot of water content. In this case, it passes the amount of less light. Many energy to enhance the durability of this stone is absorbed by it and is not fragile because of moisture. Although it is obtained at high volcanic temperature, it has preserved structure. Some solid materials inside this stone are formed to heat up to a certain temperature and the glass structure is like a solid.
The formation of perlite in nature
The stone first heats up to 2 ° C and becomes volcanic glass. Due to the heat, the water molecules in these rocks are quickly removed and converted to steam. As a result of heat, seeds such as popcorn explodes. When the temperature rises to 2 ° C, it expands and, depending on the type of combination, is entered with a thermal shock, the volume increases between 2 and 3 times.
Expansion of perlite
For the first time, perlite expansion was accidentally discovered by the dentist in year 2. Expanded perlite is a light material derived from natural perlite. For this purpose, they first crush the natural perlite stone and pass through the tour to grasp. At this time, the resulting perlite is rapidly heating and produced by a low weight, white and high volume. Expanded perlite is caused by water outflow. The peripheral water in which there is a secondary entry.
Perlite stone and various industries
The lightweight perlite is used in the production of light blocks. It is used to produce toothpaste as abrasives and is used in refineries and petrochemicals. It can be used as supplements of fertilizers in agriculture and moisture in plants. The use of this stone is used in the paper, ceramic tile, electrode production, cement production and glass fiber. Expanded perlite is widely used, for example in construction, agriculture, casting, as insulation, and so on.
