Usage areas
Due to its colloidal property and high plasticity, bentonite has the property of binding the sands used as mold material in casting.
It ensures that the drilling mud becomes viscous, the crumbs are carried up and water leaks are prevented.
With the acid activation of Ca-Bentonites, which are used to lighten the color of oils, the surface areas and spaces in the crystal are expanded, Fe, Ti, Ca, Na and K are separated from the crystal lattice structure of clay minerals, H+ - bonds are formed in their spaces, they are converted into bleaching earth and vegetable oils (olive oil) It is used as a filter material in the refining of sunflower, corn, sesame, soybean, palm, canola, cottonseed oils.
Pelletizing of bentonite iron powders with binder and plastic properties is also used.
In civil engineering, in obtaining water and liquid tightness in foundation and dam structures,
In the clarification of wine and fruit juices,
In animal feed production,
As a filling material in the pharmaceutical, paper, rubber industry,
As an additive in the cement industry, in the ceramic industry,
in oil refining,
In the cleaning of waste water,
In paint industry and fire extinguishers,
It is used in fertilizer making and soil improvement.
