Instructions for use

General-purpose graphene powder is a powder material, easy to absorb moisture, please strictly seal and store in a dry environment (humidity < 30%) before use, pre-drying; strictly seal after opening. It is recommended to use shearing, high-speed emulsification and dispersion equipment to improve the dispersion effect of this product in the slurry; before dispersion, please pre-soak the general-purpose graphene powder in the dispersion medium. The following is for reference only: In order to improve the dispersibility of graphene flakes, it is recommended to configure general-purpose graphene powder into a slurry with a solid content of not more than 2.0wt%. The specific dispersion process is as follows:
Step 1: Pre-soak the general-purpose graphene powder in the solvent for no less than 6 hours;
The second step: the pre-soaked graphene slurry is efficiently dispersed by stirring and dispersing and high-speed emulsification. Shearing stirring, high-speed emulsification dispersion and ultrasonic dispersion adopting linkage cycle operation mode is more conducive to the effective peeling and dispersion of graphene sheets. The specific method is that the graphene suspension is stirred, emulsified and dispersed for 30-60 minutes, and then the ultrasonic dispersion device is turned on, so that the dispersion is recycled for 45-60 minutes under the combined action of stirring, emulsifying, and ultrasonic dispersion.


Safe use

Please wear protective equipment such as gloves, protective glasses and face shields when using this product. Do not eat, drink or smoke when using this product. Please wash hands and face thoroughly after operation. In case of skin (or hair) contact, please take off the contaminated clothing immediately and rinse with soap and plenty of water. In case of contact with eyes, please rinse with water for more than 15 minutes. If eye irritation persists, please consult a doctor. If swallowed by mistake, drink water and rinse your mouth immediately, and take it promptly. Do not induce vomiting on unconscious patients.
