Abstract: SH is a new polymer solidified material; it may be used for sand fixation in deserts. It is a repairing material for environment. In this paper, modern analytical methods have been used. These research methods include IR spectrum, scanning electron microscope (SEM) and X-ray energy dispersive spectrometer (EDS) techniques. Microstudy of the mechanism about sand fixation with SH has been made. The results show the importance of physicochemical action. This opens out the essence of sand fixation with polymer such as SH. The result indicates that the mechanism of sand fixation by SH is more complicated. It includes a set of physicochemical processes. After SH and sand being combined, the functional group of SH has no chemical bond to sand, it is only little hydrogen bond and Fan force influence of the strength. The strength of SH-fixated sand is the result of physicochemical action such as absorb, bridge, flocculate and ion exchange, etc. SH-fixated sand is not broken out in water, and resistance to wind erosion.

Key words: polymer solidified material, sand fixation, mechanism, IR spectrum, scanning electron microscope, microstructure
