Product Description:

Composite sodium bentonite is produced by processing calcium bentonite through a series of purification techniques, including hand selection, decontamination, crushing, mixing, and extrusion, followed by sodium modification. [Applications] ① In the foundry industry, it can be used as mold sand and binder, overcoming the "sand inclusion" and "peeling" phenomena in castings, reducing the scrap rate of castings, and ensuring the accuracy and smoothness of the castings. ② In the papermaking industry, it serves as a filler for paper.

Product Details

Composite sodium bentonite is produced by processing calcium bentonite through a series of purification techniques including hand selection, decontamination, crushing, mixing, and extrusion, followed by sodium modification.

[Usage]

① In the foundry industry, it can be used as mold sand and binder, overcoming the "sand inclusion" and "peeling" phenomena in castings, reducing the scrap rate of castings, and ensuring the accuracy and smoothness of the castings.

② In the paper industry, used as a filler for paper to enhance its brightness.

③ Utilize the strong bonding properties of this product for the manufacturing of white glue, floor adhesives, paste, etc.

④ Due to its stable suspension and thickening properties, it can effectively float and disperse powders, serving as a thickening and anti-settling additive for water-based paints.

⑤ Leveraging its excellent dispersion and expansion properties, high pulp yield, low water loss, as well as colloidal properties and shear-thinning capability, it can be used as sodium bentonite for drilling mud.
