The soft, natural sedimentary rock is referred to as diatomite powder, and is created from the preserved remains of microscopic organisms known as diatoms. The secret behind this wonder material lies in its amazing ability to possess high porosity, low density, extremely large surface area and its inert chemical characteristics. Using state of the art crushing, grinding, and classification facilities and our ISO9001:2000 certified quality management system, Hebei Hezhen Industrial Co., Ltd. is able to deliver consistent quality diatomite powders with precisely tailored particle sizes to our customers. In this blog article, let’s examine some of the major industrial applications of diatomite powder in chemical process.
High-Efficiency Filtration and Clarification
Perhaps the most widely recognized use of diatomite powder in chemical industry is as filter aid. With the unique and honeycomb like porous structure of diatomite, innumerable micro channels can trap most of suspended solids while permitting liquids to pass through. This property is valuable in clarifying various kinds of chemical fluids, such as acids, solvents, oils, and liquid intermediates. They are also widely used in the food and beverage industry to purify beers, wines, fruit juices, and other sweetening agents, as well as in the pharmaceuticals industry for products requiring critical purity.
Hebei Hezhen provides both natural and calcined diatomite grades. Calcined product has higher flow rate than the natural products for some applications with higher liquid permeation required. Our strictly quality control ensures the high filtration efficiency in all kinds of conditions.
Catalyst Support and Carrier Material
The enormously high specific surface area of diatomite powders—as high as 50 m²/g—or even above, provides an excellent carrier and supporting material for catalysts and reagents. For catalysts, the highly porous structure of diatomite serves as an ideal matrix to evenly disperse and fix active catalytic sites, thereby maximizing the contact surface area with reactants and improving the efficiency of catalysts. Diatomite also works well as a carrier material in liquid or gas phase reagents which need to be released slowly in chemical processes. Its inherent high thermal stability and chemical resistance enable diatomite to perform under stringent operating conditions. Our production techniques allow the production of diatomite with different pore size structures and can fulfill specific customer needs to optimize catalytic processes.
Functional Filler and Anti-Caking Additive
In many chemical processes, diatomite powder can serve as a functional additive to enhance the properties of the products. Diatomite can be utilized as an additive in paints, coatings and plastics for matting, increase the hardness of films, and reduce the gloss of coatings. In powdery or granular products such as fertilizers, pesticides, and detergents, diatomite are excellent anti-caking additives due to their absorptive capacity, effectively preventing the products from lumping and ensuring smooth flow. They also reduce the weight of finished products without compromising their performance as their low density adds volume with minimal weight. Hebei Hezhen produces various grades of diatomite earth with different sizes suitable for the precise formulation requirements in various industries.
Absorbent for Spill Management and Environmental Protection
With their remarkable liquid absorption capabilities—able to absorb liquid at nearly twice the weight of the material—diatomite powders are increasingly being used in chemical spill management and in treatment processes for liquid wastes and hazardous materials. In industrial settings, diatomite powders can be spread over the site of a spill to absorb and contain it, making clean-up and disposal simpler, more effective and much safer. They are used in water treatment to help remove dissolved solids, metal ion pollutants and oil residues. Being non-toxic and chemically inert, it's an eco-friendly solution for pollution control and safety at workplaces. Hebei Hezhen is dedicated to providing highest quality diatomite to safeguard environment for all the chemical related industries. Hebei Hezhen Industrial Co., Ltd. looks forward to welcoming domestic and international partners to visit the workshop for in depth discussions on how diatomite powders and other non-metallic mineral products can help customers improve their chemical processes.
