When the grinded perlite is rapidly shocked at a temperature between 800°C and 1000°C the small amount of liquid is evaporated. For this reason, perlite which has high quality expands 20 times more than its unexpanded form.
Since perlite expansion furnaces reach high temperatures, energy has a large part of the production costs of perlite plants. It is great importance to apply heat insulation so as to reduce energy costs.
It is possible to provide insulation up to 1200°C regardless of the surface shape of the furnace by using the Isollat-Effective heat insulation method. Isollat-Effective advantages are as follows;
- The liquid consistency of the insulation ensures good insulation for difficult areas;
- The application process takes a short time;
- No welding is applied during insulation;
- It fits on the surface;
- It is used as a finishing coat;
- It is applied without interrupting the production cycle;
- It protects metal surfaces against corrosion;
- It lasts more than 10 years;
- Coloring is possible.
