Perlite consists of volcanic lava. When volcanic materials are on the ground, they are rapidly cool and frozen. Some of these lava have some water in their structure (about 1 to 2 percent). With the cooling of these materials with water, a dark, gray material is created pre -construction of perlite.
by heating it (temperature between 2 and 2 degrees), the water is removed from the texture and gray matter. It becomes a white, lightweight, lightweight, lightweight stone, with a granular texture called perlite. Perlite is derived from the word Pearl meaning pearl.
perlite is made of silicate. In fact, the time they heat the perlite - the silicate in its structure is soft and the water is vaporized inside. It is also called volcanic popcorn because the process of forming white seeds and steaming out of it is similar to the bursting of corn seeds.
What are the characteristics of perlite that it has used?
What are the uses of perlite?
1. In various parts of agriculture and flower and plant breeding - it is also possible to be used in hydroponic cultivation and soil -free cultivation.
2. Application in Greenhouses
1. In construction (production of materials) and concrete production - helping to lower the weight of structures
1. In the casting industry - metallurgy
1. In the process of filtration in the chemical, pharmaceutical and food industry
6. As insulation - water pipes are insulated with perlite so that the sound of water within these pipes is less heard.
7. As well as use to make jeans ore
What is the perlite block?
Perlite Block is a type of prefabricated shell building blocks based on mineral shells. The perlite block falls into the category of light blocks, which is nowadays highly regarded by engineers for the building wall.
Perlite is a mineral that in volcanic interactions and rapid cooling from 2 to 5 times. The initial volume of the material has become more volume. During volcanic activities, water in the crude material is trapped and, after hot, explosively removes the raw material and causes the perlite foam to form. Perlite foam or shell structure is the main reason for the lightness of this volcanic mineral, which is why one of the most appropriate minerals to replace sand in cement mortar and add to building material mortar, especially blocks.
The physical characteristics of building perlite
Weight of building perlite
According to the researchers' experiments, the chemical compounds have affected the stones. Silica has the largest and biggest effect, followed by iron, lime, magnesium, potassium and water oxide by increasing the specific gravity of silica, potassum and water, and the percentage of iron, lime and magnesium oxides increases.
Specific gravity. It also depends on the amount of water content. High -specific jars contain less water. Those with lower specific weight content contain higher water.
