coatings
The sagging and leveling of the coating are two contradictory phenomena, and an excellent rheological additive is needed to balance the two properties of sagging and leveling. When the paint is stored, the rheological additive forms a loose structure inside it, thereby preventing the pigment from settling. After construction, the internal structure is damaged due to external force, and the coating is easy to level. At a certain stage, the internal structure of the wet film slowly recovers the loose network structure, which is beneficial to prevent sagging. Organobentonite has amazing adsorption expansion capacity and thixotropic effect in solvents. It is used as a rheological additive in the production, construction, storage, and film-forming stages of coatings to endow the coatings with structural viscosity at low shear rates.
building materials
The main component of bentonite is lamellar montmorillonite, which is composed of a very thin (10A, 7 atoms thick) and relatively wide diameter (about 1000nm) disc-shaped material. When montmorillonite is mixed with water, it can form a card house structure, which can improve the flow behavior of construction mortar.
water treatment
Bentonite-based paint wastewater purifier, quickly treats water-based industrial paint paint, collects wastewater and recycles it. Reduce the solid content, turbidity and other indicators of wastewater to meet the rapid treatment of different types of coating wastewater.
papermaking
Microbentonite for paper retention and drainage aids is mainly used in paper production. Improve the retention of papermaking fibers, fillers, etc., and improve drainage. And helps to improve the formation of the finished paper, especially in the production of tissue paper. This product also absorbs stickies etc. to prevent resin barriers.
oilfields
High-quality bentonite can produce high-quality mud, which can effectively prevent hole collapse, protect well wall, cool drilling tools, lubricate drill pipe, balance surface pressure and increase drilling rate. When there is external stirring, the suspension appears as a sol solution with good fluidity. After the stirring is stopped, it will arrange itself into a three-dimensional network-like gel without sedimentation and water separation.
pesticides and others
1. Increase the adsorption of pesticides; 2. Bentonite has good hydrophilicity, dispersion and suspension, thereby increasing the stability of liquid pesticides; 3. Filter the impurities in pesticides to produce more pure pesticides.
