The chemical composition of diatomite is mainly SiO2, containing a small amount of Al2O3, Fe2O3, CaO, MgO, and organic. Diatomite density 1.9-2.3g/cm3, pile density 0.34-0.65g/cm3, specific surface area 40-65g/cm3 pore volume 0.45-0.98m³/g, water absorption is 2-4 times its own volume, melting point 1650C-1750ºC, can be observed under the electron microscope special porous structure.
Diatomaceous earth filter aids are light in weight, chemically inert, and form high porosity filter cakes to maintain free-flow of the liquid. Specifically, an efficient filter aid is characterized by the following:
The structure of the particles must be such that they will not pack together closely, but will form cakes that are 85% to 95% pore space. This not only permits higher initial flow rates, but also provides pore spaces to trap and contain the filterable solids while leaving a high percentage of channels open for flow.
diatomite powder and diatomite graunles, natural, calcined, and flux calcined
Grade: food grade, industrial grade, chemical grade, agricultural grade .
Diatomite powders / diatomaceous earth powders : white
Diatomite graunles / diatomaceous earth graunles: yellowish
Granular Diatomite have 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.
