Guar Gel Formation |
| 配制方法： |
The addition of samll amounts of borate ion to an alkaline guar sol causes a cohesive structual gel to form due to the crosslinking of the cis hydroxyl groups of guar with the pentavalent boron. This solution-gel transformation is reversible by adjusting the pH below 7.
the new sol will have the same viscosity as the original sol. |
