Study on the failure mechanism of a modified hydrophilic polyurethane material pisha sandstone system under dry-wet cycles

HIGHLIGHTS

  • who: Wenbo Ma and collaborators from the School of Mechanical Engineering and Mechanics, Xiangtan University, Xiangtan, China have published the Article: Study on the Failure Mechanism of a Modified Hydrophilic Polyurethane Material Pisha Sandstone System under Dry-Wet Cycles, in the Journal: Polymers 2022, 14, x FOR PEER REVIEW of /2022/
  • what: Montmorillonite is extremely swellable when exposed to water, with a maximum swelling rate of 150%, and is the main reason why the Pisha sandstone is susceptible to collapse when exposed to water . This paper focuses on the failure mechanism of the W-OH . . .
