Description

technical field

[0001] The invention relates to the field of research on the hydration of clay materials under different activity conditions, in particular to a high-precision multi-activity isothermal adsorption experimental device capable of automatically recording and processing data. Background technique

[0002] The water swelling of clay plays an important guiding role in the study of the stability of drilling fluid to the borehole wall and the construction and improvement of drilling fluid system, and isothermal adsorption is an important method to study the adsorption capacity of clay. The isothermal adsorption experiment has very high requirements for accuracy. In the case of a large number of samples, the experiment cycle is very long, and it is greatly affected by environmental factors and human factors. The experimental process is cumbersome, and uncertainties in the middle often lead to experimental failure or experimental result errors. If it is too large, it w...
