PERLITE FILTER AID |
|
Perlite in the natural state is a dense glassy rock formed by volcanic action. When crushed and treated
under proper conditions, it pops like popcorn, expanding to 20 or more times its original volume. A
special milling and classification process gives our perlite filter aids the structure and correct particle size
range distribution needed for optimum performance.
Perlite is an amorphous mineral consisting of fused sodium potassium aluminum silicate. Our perlite filter aids are processed at temperatures exceeding 800°C (1500°F) which eliminates organic matter. They have extremely low solubilities in mineral and organic acids at both low and high temperatures. Solubility in strong alkalis will vary according to temperature and time of contact. Dicalite perlite filter aids do not impart taste or odor to liquids being filtered. A major advantage of Dicalite Perlite Filter aids is that most weigh less per unit volume than standard diatomite filter aids. Pound for pound, this gives up to 20% greater filtering capacity resulting in comparable savings in filter aid usage, especially on rotary vacuum per-coat filters.
