HY series aqueous system bentonite thickening rheological agent (inorganic gel) is a natural aluminum, magnesium silicate thickening rheological agent, is a purified modified montmorillonite clay, gray-white, non-toxic and tasteless, soft texture powder, the main ingredient is hydrophilic high-purity (modified) montmorillonite, its colloid is similar to the Veegum or Magnabhte colloidal products of Vanderbilt and Colloid companies in the United States. It has excellent swelling, colloidal dispersion, suspending, thickening and thixotropy in water, and is an excellent anti-sedimentation agent, latex stabilizer and rheological aid for aqueous systems. It also has good adsorption, ion exchange, non-migration adhesion, etc. In some fields, it has gradually become an excellent new substitute material for additives

First, characteristics:

1. Strong thixotropy: high shear and low viscosity, low shear and high viscosity, thixotropy index up to 6.0

2. Wide range of pH adaptation: Thickening function can be exerted within the range of PH5-12.

3. Easily dispersible: No need to prepare pre-gels or polar activators.

4. Stability: Excellent biochemical stability and good thermal stability.

5. Compatibility: It has good compatibility with alcohols and high polar solvents such as glycerol and sorbitol.

6. Economy: Use alone can significantly reduce costs, and it can be used with cellulose ethers and acrylic thickeners to improve the rheological properties of coatings.

HY series bentonite rheological additives (inorganic gel) quality index

Note: Recommended viscosity test method: 25 ℃, made of 5% uniform colloid, let stand for 60 minutes, with Brookfield Dv II viscometer, 6 #rotor, 100 rpm test.

How to use:

Pre-gel usage:

HY series bentonite (inorganic gel) thickening rheological agent can be used as a pre-gel: the concentration of the pre-gel should be determined according to the stirring speed of the dispersion equipment and the required viscosity of the product to obtain the best effect, generally 2-10% (mass percentage).

Weigh a certain amount of this product and slowly add it to water at 25-30 ° C under stirring, paying attention to avoid agglomeration. After the product is added, adjust the speed to 1000-1200RPM, stir and disperse for 30 minutes, so that the product is fully dispersed in water to form a uniform gel, and then leave it for 8-24 hours. Use it after the colloid has played a thickening role and stabilized.
