Graphene heat dissipation coating ultra high speed disperser

Graphene heat dissipation coating high-speed disperser, graphene powder coating disperser, graphene heat dissipation coating disperser, graphene coating grinding and dispersing machine, high-speed graphene grinding and dispersing machine drives the rotating teeth (or rotor) and matching fixed teeth (or stator) to rotate at high speed through belt transmission. The processed material is pressurized by its own weight or external pressure (which can be generated by a pump) to generate downward spiral impact force. When passing through the gap between the fixed and rotating teeth (adjustable gap), it is subjected to strong physical effects such as shear force, friction force, and high-frequency vibration.

Powder coating is a new type of solvent-free, 100% solid powder coating. Powder coating has the characteristics of solvent-free, pollution-free, recyclable, environmentally friendly, energy-saving and resource saving, reducing labor intensity and coating mechanical strength, etc. Powder coating is a completely different form from general coatings, existing in the form of fine powder. Due to the absence of solvents, it is called powder coating. The main characteristics of powder coatings are: harmless, efficient, resource-saving, and environmentally friendly; Polypropylene powder coating has excellent corrosion resistance, chemical resistance, excellent electrical insulation, and UV radiation resistance. The disadvantage is that the mechanical strength is not high and the adhesion to the substrate is poor. Can be used for chemical tanks, impellers, pumps, pipeline inner walls, instrument casings, metal sheets, refrigerator inner panels, automotive components, etc;

At present, in order to improve the heat dissipation performance of powder coatings, various heat dissipation additives are often added, including carbon nanotubes, aluminum nitride, silicon nitride, aluminum oxide, * * *, magnesium oxide, silicon carbide, etc. The thermal conductivity principle of these traditional heat dissipation additives is roughly as follows: their own high thermal conductivity or the formation of interconnected channels inside the polymer matrix to improve the heat dissipation effect. However, the compatibility between these inorganic fillers and the polymer matrix is poor, which can easily reduce the stability and strength of the coating and reduce the protective effect on the substrate.

However, the heat dissipation coating with graphene added is different. It not only does not have the above-mentioned problems, but also greatly improves its performance.

To ensure the uniform dispersion of graphene in the polymer matrix, it mainly depends on two factors: the selection of dispersants and dispersion equipment. The Taicang Xide XMD2000 series grinding and dispersing machine can effectively solve problems such as easy agglomeration of particles or powder slurry, uneven dispersion and refinement. The SID grinding and dispersing machine has 4-5 times the speed (14000 rpm) higher than the ordinary dispersing machine (high speed 2930 rpm), with stronger force and better shear dispersion effect; The equipment is equipped with a jacket that can heat and cool goods according to demand; The medium in the working chamber and tank jacket can be supplied with water/coolant/liquid medium in the slurry/thermal oil according to the needs; The gap between the stator and rotor is only 0.2-0.4mm (adjustable gap, controllable grinding fineness), while the gap between the stator and rotor of a regular disperser is over 1mm.

The stator has three-stage sawtooth protrusions and grooves with increasing fineness, which can be adjusted wirelessly to the desired distance between the stator and the rotor. Under enhanced fluid turbulence, the grooves can change direction at each stage. This design ensures that when the initial particle size of the material is large, it can smoothly enter the grinding and dispersing machine chamber, and obtain micro - and nano scale material particles through the high-speed rotating grinding head that gradually increases the fineness.

Grinding and dispersing machine level 2Composed of a stator. The design of the dispersing head also effectively meets the needs of substances with different viscosities and particle sizes. The main difference in the design of the working heads of online stator, rotor, and batch machines lies in the requirements for conveying performance. It is particularly noteworthy that the differences between coarse longitude, medium longitude, fine longitude, and other types of working heads are not only in the arrangement of specified rotor teeth, but also in the geometric characteristics of different working heads. The number of slots, slot width, and other geometric features can change the different functions of the stator and rotor working heads. According to past practice, designate a work head based on past experience to meet a specific application. In most cases, the construction of a machine is tailored to its specific application, making it crucial for producing the ultimate product. When it is uncertain whether the construction of a working head meets the expected application.
