The particle surface property analyzer analyzes the dispersibility by the specific surface area of ​​the particles in a solvent. The larger the specific surface area, the better the dispersibility, and the specific surface area refers to the entire area (wet specific surface area) in contact with the solvent. The method can also monitor the dispersibility of the particles in real time, and the dispersant performance can be evaluated by this method to optimize the formulation of the slurry.
The specific surface area of ​​the battery material is particularly important. The specific surface area has a great influence on the preparation of the slurry and the coating of the pole piece, and has a great influence on the first coulombic efficiency and cycle performance of the battery. The porosity is also important for high rate charge and discharge. The effect ultimately affects the cycle life of the battery (such as the graphite specific surface area is too large, resulting in excessive capacity loss for the first time, reducing the service life. And the added binder will be more, resulting in increased internal resistance)

The manufacturing process of the battery pack;
The performance of solar cell photosensitive particles;
Fuel cell production cost control
Application case - graphene dispersion effect test
This method can effectively evaluate the dispersion effect of the dispersant on a specific substance.
Specific surface area test
Uses and functions: It can quickly measure and analyze the surface of particles as small as nanometer size in suspension.
Main properties of particle surface analyzer:
1) The sample does not need to be diluted and no pretreatment is required;
2) directly measuring the contact area of ​​the material with the liquid in the suspended state;
3) The measurement results are obtained in a few minutes;
4) High degree of automation, easy to use, no training required.
The electric Nursing Bed is used for the treatment and rehabilitation of patients or the elderly. At the beginning, it was mainly used in hospitals. With the development of the economy, electric nursing beds have also entered ordinary households, becoming a new choice for home care, greatly reducing the burden on nursing staff.
Electric nursing bed,in addition to lying flat, the back deck of the bed can be raised and lowered within the range of 0°-80°, and the foot deck can be raised and lowered within the range of 0°-50°. Patients can choose a suitable angle of sitting on the bed to meet the needs of eating, taking medicine, drinking water, washing feet, reading and newspaper, watching TV and moderate physical exercise.
Our selection features - Electric Nursing Bed, Manual Nursing Bed, Nursing Home Bed, Hospital Nursing Bed, etc. We really do have a nursing bed to suit anyone and their requirements.
