Bentonite application
Drilling bentonite: Bentonite is the main material of the preparation of slurry. It has the effection of protecting sidewall, upward returing cuttings, cooling and lubricating the bits.
Foundry bentonite: Bentonite is used in agglomerant and lithium bentonite is used in quick-drying coating.
Iron core pelletizing bentonite: It can improve the production capacity by adding 1-2% sodium bentonite in the refined iron-mineral powders. It is widely used in steel mills.
Coating bentonite:Bentonite is used as suspending agent in various coating. It can improve the suspension, adhesion, brushing property and water resistance of the coating.
Animal feed bentonite: Bentonite can be used as additives of animal feed because it contains a lot of microelements such as Fe, Cu, Zn and Mn and it's non-toxic and fine powder.
Fertilizer bentonite: It can improve the fertilizer effection and improve the soil.
Building bentonite: Bentonite has good effection of anti-leakage in construction.
Rubber bentonite: Bentonite has better swelling rate,high water absorption.
