Production process Introduction
Source factory, high quality, and low price.
Calcined Kieselguhr is a type of diatomaceous earth that has been calcined at high temperatures to form a high-hardness, porous structure. It is used to improve solid-liquid separation efficiency and is widely used in food, chemical, and environmental filtration processes.
Advanatges
High filtration efficiency: Multi-stage micropores trap fine impurities, improving liquid clarity.
Strong chemical stability: High SiO₂ content (≥85%), stable structure after calcination, does not react with acidic media, suitable for food and chemical filtration.
Not prone to pulverization: Calcination enhances particle strength, reducing pulverization during filtration.
Safe and environmentally friendly: Natural mineral, treated at high temperatures to remove impurities, free of organic pollutants, suitable for food, beverage, and pharmaceutical production.
Product Technical Data Sheet
Low density, high whiteness, low viscosity, and high purity.
