The arrays were resistant to pH values as low as 4 and as high as 12, temperatures as low as −70 °C and as high as 100 °C, and high salt concentrations of 2 M NaCl and 2 M MgCl 2. At pH 13, only a portion of the arrays were degraded (Figure 2, lane 15).

Mar 21, 2020 · It has been reported that low concentrations of hydrophobic monomers can improve viscosity modification, shear resistance, temperature resistance, and salt tolerance compared to traditional HPAM [12,34,38]. Representative polyacrylamide-based materials are listed in Table 1; acronyms are defined following Table 1. Many of the polymer properties ...

hydrolysis, sunlight, salt. and temperature effects (Azzam et al., 1983; Wallace et al., 1986; Tolstikh et al., is known. When PAM is mixed thoroughly with soil, it degrades slowly (about 10% per year) as a result of mechanical degradation, chemical and biological mandated total maximum daily loads (TMDLs) for specific contaminants.

How does Polyacrylamide works in Bored Piling? There are two usage in bore piling: Polyacrylamide could be used like building glue additive, because of the high viscosity and water retention. So it could be mixed in slurry of borehole wall to get better efficiency. The cationic polyacrylamide is suggested. Slurry is important to protect borehole wall, but surplus slurry …
