Figure 2.9 and Figure 2.10 are the resin and 2000 times 4000 times magnification scanning photos, you can see, the product has formed a three-dimensional network structure, which is water absorbent resin to the structural causes.

Figure 2.9 and figure 2.10 respectively resin is magnified 4000 times, and 2000 times the scan picture, it can be seen that the three-dimensional dimensional netlike configuration product has already formed, and that is able to absorb water-absorbing resin structural causes of water.

Figure 2.9 and Figure 2.10 respectively is the resin enlarges 4000 time of and 2000 time of scanning pictures, may see, the product has already formed the three-dimensional network structure, this was the structure reason which the absorbent resin can absorb water.

Figure 2.9 and 2.1, respectively, is a resin 4,000 times times and 2000 times scans of photos, we can see that the product has formed a solid network structure, this is the water-absorbing resin to cause water absorption structure.

Figure 2.9 and Figure 2.10 are the resin and 2000 times 4000 times magnification scanning photos, you can see, the product has formed a three-dimensional network structure, which is water absorbent resin to the structural causes.
