brief introduction

smp water thickening agent is a high purity montmorillonite clay, which is purified and nano modified, which is a white or light gray powder, non-toxic and tasteless, soft texture. in water with excellent expansion and colloidal dispersion, suspension, increasing the viscosity and thixotropy is water system of excellent anti settling agent, emulsion stabilizer and rheological additives. this product also has a good adsorption, ion exchange, non migration and adhesion, in the water dispersion system has a wide range of applications.

the main chemical components of smp high purity nano montmorillonite are silica and three aluminum oxide two. by two layers of silicon oxygen tetrahedron sandwiching a layer of aluminum eight surface form single layer, layer stack is formed montmorillonite granules. the single layer thickness is only 0.96nm, which belongs to one dimensional nano inorganic silicate material. the montmorillonite layers with electronegativity, layers and layers with ion exchange, of layers of different types of ion exchange modified montmorillonite flakes layer polarity change. smp high purity nano montmorillonite inorganic silicate layers structure has good thermal stability and application in the field of polymer materials, the montmorillonite layer through fully dispersed with good flame retardant and barrier properties.

pre gel method: weigh quantitative sm high purity montmorillonite, in under the condition of stirring slowly added to the 25 to 35 deg c water, avoid caking, increase the speed to 1500-2000rpm dispersed 20-30min, making montmorillonite fully swell and disperse and form a homogeneous suspension, placing 8-12h. set aside. then under the stirring condition according to the measurement of the bentonite suspension was added to the required system to fully disperse and mix. (general montmorillonite in water pre dispersion concentration in 8-15%). the general pre gel than the direct dispersing method for the dispersion, use the effect will be better.

outside the package of kraft paper bag, the inner packing uses the double layer packing of the polyethylene film bag, or the paper bag packing, the weight is usually 25 0.25kg, or by the user request packing. under the condition of dry condition, the temperature is 0~30, and the quality is 24 months.
