YH series water-based rheological additive

1. RHEOLOGICAL ADDITIVE

YH series water-based bentonite rheological additives (inorganic gel) is a kind of natural aluminum, magnesium silicate, rheological additives. It is a purification of modified montmorillonite clay with the features of gray-white, non-toixc, tasteless, soft texture powder, the main ingredient for the product is hydrophilic, high-purity (modified) montmorillonite, its colloidal system is similar to Vanderbilt and Colloid Company’s Veegum or Magnabrite products. With excellent swellability in water, colloidal dispersion, suspersion, thickening and thixotropy, it is the excellent anti-settling agent, emulsion stabilizers and rheological additive for water-based system, and further it has good adsorption, ion-exchangeablity, non-mogration adhesion, etc. In some areas, it is becoming an excellent assistant new type of alternative materials.The performance of the products in many respects are superior to separate organic polymer such as CMC, HEC.

4. THE MAIN CHARACTER AS FOLLOW:

Strong thixotropic:high shear with low viscosity;low shear with high viscosity.the index of the thixotropy reach to 6.0

Extensive  PH range of application: It will go into effect during PH5-12

Easy dispersivity: Need no pre-gel and active agent.

Stability:fine biochemical stability,and fine heat stability.

Mutual solubility:Easy to dissolve in the alcohols and high polar solvent(glycerin,sorbitol).

Economical Efficiency: it will reduce the cost when using the product alone.Also,Mix with the cellulose aether,acrylic acid will improve the rheological property,and reduce the costs at the same time!

Attention: Recommended viscosity test method: at the temperature of 25℃, make a pre-gel (the amount of bentonite is 5% of the total system) stand it for 60 minutes, test the viscosity with a Brookfield DV II viscometer with the rotor #6, 100 r/min.

Ues method

(1) pre-gel  method:

The YH series bentonite(inorganic gel) rheological additve could be used as pre-gel:the preparation of a pre-gel concentration should be according to the desired viscosity level of the stirring speed and the product of the dispersing device in order  to obtain the best results. Generally speaking,2-10%(mass percentage of the whole system)/ Weigh a certain amount of
the product of the product under stirring slowly added to water of  25-30℃ note avoid caking.After the addition, adjust the speed
to 1000-1200RPM,and disperse it by stirring for 30 minutes,so that products can sufficiently disperse into the water and form a
unform gel ,stand it for 8-24 hours,and use it after the colloidal plays stabilized thckening effect.

(2) Dry powder method:

YH series bentonite rheological additives (inorganic gel) can be directly put into required system and dry powder.Formulated cincentration of the system should be decided according to the needs of the various indicators of the stirring speed and the dispersing device (viscosity level ,thixotropy,ect.)

Attention

(1) YH series inorganic gel will take effect under the condition of dispersing enough. It will increase the function of thickening, anti settling, thixortopy of the gel is proper stored Surface activator, diatomic alcohol will disturb the hydration, it should be added after YH Series dispersed enough.

(2) YH series inorganic gel can be used alone or mixing with thickening agent such as carboxymethyl cellulose,hydroxy ethyl cell ulose, CMHPC,which will acquire best rheological property.It has been found that this kind of product should avoid mixing with the polyurethane thickening agent.
