Sodium bentonite brief introduction:

Bentonite is using natural bentonite modification of lithium carbonate with sodium base bentonite 

flooding hydration expansion, performance and characteristics of organic bentonite, both in water and polar organic

solvents such as ethanol swelling can dissolve into colloid or fully that the viscosity of coating. Suitable for 

water-based paint, refractory anti-rusty coating as thickener, suspension stabilizer, make coating viscosity increases 

and making particle surface solvation thin film and the three-dimensional network structure to support and prevent grain sinks. This kind of coatings in metallurgical casting sand

mold surface, because of volatile solvents ethanol can quickly form the dry membrane layer, as well as smelting 

furnace sand mold and making casting more bright and clean.

Bentonite is a kind of extremely valuable, multipurpose non-metallic minerals, enjoy the "universal" clay. 

Its products has excellent performance, such as sexual dispersive, suspension, thixotropy, rheological property, adsorption, bentonite plasticity, cohesiveness, cation 

exchange, etc., can be used as a binding agent, suspending agent, thixotropic agent, plasticizer, thickener, lubricants, 

flocculating agent, stabilizing agent, catalyst, purifying bleaching agent, clarifying agent, filling agent, adsorbent, chemical carrier and other widely used in petroleum, metallurgy, chemical, foundry, construction, plastics, rubber, coating, light industry, environmental protection, etc.

Bentonite is mainly used for various kinds of precision casting industry alcohol-based coating suspending agent, sand binder and many kinds of ceramic colored glaze coating, used as basic material of suspending agent, thixotropic agent, the precipitation agent. Used for latex paint and other daily-use chemical industry, which is then used as a suspension emulsion and paste thixotropic agent, emulsion stabilizers, strong polarity oil solvent of thickener, also can be used as a sizing agent on the fabric.

Method of use: 

(1) Bentonite products lithium modified bentonite to 1:1 than water wetting, fully mixing evenly, make soil paste evenly.

(2)Add a small amount of alcohol solvent mixed pressure, then add the refractory material, binder, additives, such as alcohol solvent to mixed pressure into coating paste.

(3) Join the alcohol solvent dilution, mix into a certain viscosity of coating, coating or coating on surface of molding sand, **4 min after the fire to dry.

(4) do alcohol-based piece of dry coating, the added amount is **4%.of refractory material.
