Cyclohexane white carbon black rubber disperser
White carbon black rubber high-speed disperser, white carbon black disperser, rubber particle disperser, ethane high-speed disperser, styrene butadiene rubber high-speed disperser areTo be used for homogeneous dispersion of white carbon black in solvents such as cyclohexane, preparation of white carbon black slurry, and liquid-phase mixing of white carbon black with solution polymerized styrene butadiene rubber.
White carbon black and adhesive solution are added separately to the pre mixing tank and pre mixed first. Then it is processed in a dual inlet high shear disperser, entering from different material ports and entering the working chamber at the same time. After shearing and dispersing, it can be directly ejected or recycled back to the white carbon black premix tank for further processing.
2.1 Based on the specific materials and working conditions of the research institute, it is recommended to use a dual inlet three-stage online high shear disperser. The disperser has a three-stage structure, with the * stage being a spiral blade, which is beneficial for absorbing white carbon black; The second stage is 6F; the third stage is 8SF. The second and third stages are equipped with dense dispersion disks for better refinement and dispersion of white carbon black slurry.

2.2 Two pre mixing tanks in total
a. White carbon black mixing kettle, used for dispersing white carbon black.
Equipped with a three-layer continuous high shear disperser, it is used for pre dispersion of powders and liquids. After dispersion, it enters the high shear dispersion process, and the piping can circulate; Effective volume is 20L, normal pressure, room temperature -50 ℃, electric frequency modulation stirring at 500r/min, bottom valve discharge, temperature and pressure display, with nitrogen displacement and liquid feeding pipe opening
b. Gel mixing kettle, used for dispersing white carbon black and mixing gel.
Equipped with a three-layer continuous high shear disperser, it is used for pre dispersion of powders and liquids. After dispersion, it enters the high shear dispersion process, and the piping can circulate; Effective volume is 20L, normal pressure, room temperature -50 ℃, electric frequency modulation stirring at 500r/min, bottom valve discharge, temperature and pressure display, with nitrogen replacement and liquid feeding ports.
Grinding and dispersing machine is a high-tech product composed of colloid grinding and dispersing machines.
The first level consists of three-level sawtooth protrusions and grooves with increasing precision. The stator can be infinitely adjusted to the desired distance between the rotors. Under enhanced fluid turbulence. The groove can change direction at each level.
The second stage is composed of a stator. The design of the dispersing head also effectively meets the needs of substances with different viscosities and particle sizes. The difference in the design of the stator and rotor (emulsifying head) between online and batch machines is mainly due to the requirements for conveying performance. It is particularly important to note that the difference between coarse precision, medium precision, fine precision, and other types of working heads is not only the arrangement of specified rotor teeth, but also an important difference in the geometric characteristics of different working heads. The width of the slot and other geometric features can alter the different functions of the stator and rotor working heads.
