DE Absorbent

graininess absorbent is after drying, shivers, griddle, calcined, and regriddle from the natural diatomaceous earth.

According the size of granules, Graininess Absorbent is classified in four grades:

Diatomite graininess absorbent has irregular shape, good adsorption capacity and intensity, fireproofing, innocuity and odorless, and it's easy to reclaim after the operation of water or oil absorption. So the CD™ graininess absorbent is widely used in the following areas:

A. Used as anti-caking agents in anti-deoxy agent of food preservation.
B. Used as desiccant in electronic equipment, precision instruments, medicine, food and clothing.
C. In the area of environmental protection, used as floor absorbent for the penetrated harmful liquid.
D. Used as soil conditioner in the golf course, ball park, and lawn, in order to improve the players' applicability while the climate changed, and to improve the lawn livability and pruning efficiency
E. In animal production units used for the control of external parasites and flies, and as bedding area for pets.

DE Catalyst Carrier

The ideal, inert, porous support—catalyst carrier

The unique physical properties of diatomite fillers make them an ideal support for catalysts in many industrial processes. Available in powder, and pelletized forms, they are widely used wherever an inert, porous silica support is indicated—for the nickel catalyst used in hydrogenation processes, the vanadium catalyst used in the manufacture of sulfuric acid, the phosphoric acid catalyst of the petroleum industry. They are also available as custom-designed supports, in a variety of applications, including the biotechnology industry where catalyst carriers are used for enzyme and microbe immobilization.

With their high porosity and irregularly shaped particle structure,, Diatomite Catalyst Carrier in powder form provide unusually low loose and packed weight densities. This property reduces structural stress and contributes to the economy of reactor equipment design. More weight of active catalyst per unit of catalyst support volume can be packed into a reactor, with more efficient dispersion of the catalyst material. Our diatomite with its relatively large available surface area as compared with that of other inert carriers provide a most efficient means of preparing supported catalyst with high surface area and small pore structure.

Other characteristics of diatomite catalyst carrier include high strength and stability at elevated temperatures. The minute diatomite particles do not break down under heat or steam, or under the most severe operating conditions. The pelletized forms have high compressive strength and are strongly resistant to attrition, even under heavy loading.

DE Filter Aid

DE Filter Aid

Diatomite is porous with lower density and larger surface area; it has relative incompressibility and chemical stability. Diatomite as the important raw materials, after grinding, drying, sorting, calcined, classified, residue removed, we get the thing that can improve the quality and efficiency of filtration is called Diatomite Filter Aid。
