Product function：The main functions are anti sinking, anti sagging, thixotropy, improving construction performance and drying conditions.

product mix：SHV is a kind of montmorillonite with layered "enriched flake" structure, which belongs to silicate products. Its microstructure is characterized by silicon oxygen tetrahedron at both ends and Lu oxygen octahedron in the middle. In water, due to the wetting and continuous "flaking" of the layered "enriched flake" by water molecules, more "flakes" can be dispersed in a certain hydration space, and the "flake" edge can not be separated With positive charge at the edge and negative charge at the end of the plane, SHV is gradually formed into a "stuck structure" under the principle of "positive" and "negative" absorption. The macroscopic appearance is gelatinous, which is pseudoplastic fluid, which is characterized by typical thixotropy, low shear and high viscosity, high shear and low viscosity. It is easy to pass through without being damaged;

The details are shown in the figure below：

The formation of SHV "Ka ha structure" can be seen in
. A good montmorillonite rheological agent is mainly expressed in the same amount of added water. The more stable the "stuck" structure is, the more stable the gel is, the more extensive the "rich slice" is stripped and the more dispersed it is, the more full the structure of the card is, the more efficient the gel thixotropy is.

Typical characteristics of SHV montmorillonite clay gel：
1、Nanostructured flexible sheet
2、There is a negative charge in the middle and a positive charge at the edge
3、The flakes can expand and separate in water and polar solvents
4、High specific surface area
5、Locking water but not absorbing water helps to prevent water separation, but does not affect the drying of the system

Only montmorillonite clay gel like SHV is called high efficiency. Its main performance in the practical application of waterborne industrial paint industry is as follows: (low shear, high viscosity, easy storage, high shear and low viscosity, easy for construction). A. Increase the yield value, increase the sinking resistance and sagging resistance < br/> B. thixotropy thickening, convenient for construction
C. increase the thickness of construction film, easy for thick coating
D. increase the storage stability, convenient for transportation

SHV montmorillonite clay rheology agent is a broad spectrum inorganic thixotropic agent, suitable for acrylic emulsion, waterborne epoxy resin, water dispersible alkyd resin, polyurethane, polyester and other systems, as well as the vast majority of polar cosolvent systems.

spray drying
Pure inorganic materials
5% viscosity is more than 6000 (6 rotor / 60 revolution, standing for 12 hours), while ordinary pure inorganic montmorillonite 5% viscosity is about 1000
The gel has good stability and good viscosity in polar solvents such as alcohols, ethers and esters, while ordinary pure inorganic montmorillonite is layered in polar solvents, and the viscosity is poor.

Specific pulping methods
Prefabricated gel is fully cut (1500 /15 minutes) without adding bactericidal preservatives.Pure inorganic material, can normally participate in sand grinding，When it is used in polar solvent, water is needed to activate and then the solvent system is added。
Recommended addition： 0.3%—2%（ Waterborne zinc rich epoxy resin 1—2%；Other systems 0.3—0.5%）
