Vermiculite Details
Products Description
After the raw vermiculite flakes are calcined at high temperature, their volume can rapidly expand several times to dozens of times. The expanded vermiculite is called expanded vermiculite. It has a layered structure with crystal water between the layers, and the bulk density is 50-200kg. /m3, the thermal conductivity is small, and the surface of the particles has a scale structure, which can reflect heat radiation, so the expanded vermiculite has thermal insulation properties.
Features
1. Lightweight：Expanded vermiculite is relatively light relative to its volume, which makes it useful in some applications where weight savings are required
2.Low thermal conductivity:This makes it excellent in the field of thermal insulation, which can effectively prevent heat transfer, and is suitable for thermal insulation and thermal insulation materials for high-temperature equipment
3.Good chemical stability:Expanded vermiculite has good resistance to many chemical substances, especially high stability to acidic solutions
Application
As a refractory material, vermiculite has a wide range of application scenarios in various high-temperature industrial applications due to its high temperature resistance and chemical stability.
1. Furnace and kiln lining: It is often used to manufacture refractory bricks, refractory coatings and refractory castables, and is used to build linings for high-temperature equipment such as furnaces and kilns. It can withstand chemical erosion and thermal stress in high-temperature environments, ensuring long-term stable operation of equipment.
2. Iron and steel smelting: In the process of iron and steel smelting, it is widely used in the lining of blast furnaces, converters, electric furnaces and other smelting equipment, as well as refractory linings in steelmaking, casting and other processes.
3. Oil refining and petrochemical industry: In oil refineries and petrochemical plants, it is used for the lining of high-temperature reaction equipment such as cracking furnaces, catalytic cracking units, and coking units, as well as the maintenance of petrochemical equipment at high temperatures.
