(2500g) Sodium Bentonite Clay Powder Drilling Foundry

(2500g) Sodium Bentonite Clay Powder Drilling Foundry DescriptionSodium Bentonite is used in foundry, metallurgy, well drilling slurry, oil, agriculture. Bentonite is also used in chemical industry, environmental protection, zoology construction, ecological construction, building, paper making, textile. Bentonite also can be used in printing & dyeing, ceramics etc. This clay is Engineering grade and suitable for use in engineering projects. It is commonly used for sealing ponds, lakes, landfill sites, lagoons etcSodium Bentonite is not recommended for cosmetic applications.When bentonite is mixed with water, the water molecules will enter between the clay plates, forcing them apart. While the plates are dispersed, the bentonite slurry becomes quite fluid. However, on standing the particles become oriented with the negative surfaces of the plates being attracted to the positive edges. Viscosity increases and a gel is formed – a reversible effect known as thixotropy.
