Pearlescent sand, also known as expanded perlite, is widely used in the insulation box of air separation equipment due to its excellent thermal insulation performance. It has the characteristics of low thermal conductivity, good insulation performance, good chemical stability, lightweight, and easy construction.
Application of pearl sand in the cold insulation box of air separation equipment: 1. Filling material: Pearl sand, as the filling material of the cold insulation box, can effectively isolate the influence of external heat on the low-temperature environment inside the cold insulation box. 2. Cold insulation effect: Due to the low thermal conductivity and good insulation performance of pearl sand, it can significantly improve the cold insulation effect of the air separation equipment's cold insulation box and reduce the loss of cooling capacity. 3. Maintenance cost: Pearl sand has a long service life and is not prone to performance changes during use, which can reduce the maintenance cost of air separation equipment.
Therefore, the majority of the insulation materials filled in the insulation box of the air separation equipment are made of pearl sand, which benefits from its excellent thermal insulation performance and chemical stability.
