Thermal conductive silicone grease, commonly known as heat dissipation paste, is a thermal conductive organic silicone grease composite made from organic silicone as the main raw material and added with materials with excellent heat resistance and thermal conductivity. It is used for thermal conductivity and heat dissipation of electronic components such as power amplifiers, transistors, electronic tubes, CPUs, etc., thus ensuring the stability of electrical performance of electronic instruments and meters. Thermal conductive silicone grease, also known as heat dissipation paste or thermal conductive paste, is a high thermal conductivity insulating silicone material. The product also has the advantages of low oil separation (approaching zero), high and low temperature resistance, water resistance, ozone resistance, and weather aging resistance.

Preparation of thermal conductive silicone grease: Traditional method uses silane coupling agent to treat ceramic powder, continuously stirring, dissolving, adding powder, and continuing stirring; Adjust the pH value to around 10, use a 60 degree water bath, stir for 3 hours, and disperse with ultrasound for 15 minutes. After drying, add fillers and silicone oil in proportion, and put the mixture into a grinder to grind dozens of times to obtain composite materials. This preparation method is time-consuming, labor-intensive, and very cumbersome; The new preparation only requires the mixed fillers and silicone oil to be introduced into the colloid mill in a certain proportion, ground for a few minutes, and cooled to obtain the composite material. After testing, the particles are fine and uniform, and the performance is better.

The colloid mill XMD2000 series is especially suitable for the production of colloidal solutions, ultra-fine suspensions and lotion. In addition to high speed and flexible adjustable stator rotor clearance, XMD operates in a frictional state, also known as wet grinding. There is a wide inlet gap and a narrow outlet gap between the conical rotor and the stator. During operation, the eccentric operation of the dispersing head causes eddy currents in the solution, thus achieving better grinding and dispersing effects. The XM2000 machine adopts a grinding fixed rotor with excellent geometric mechanism, excellent surface treatment and high-quality materials, which can meet various needs of different industries.

Comparison of performance between SID colloid mill and domestic colloid mill:
1、 Rotational speed and shear rate:
SID colloid millGerman mechanical seals can be selected, with a speed of up to 15000 revolutions per minute
F=23/0.7X1000=32857 S-1
F=40/0.7/X1000=57142 S-1
Domestic colloid millMechanical seals can be selected, typically at 3000 revolutions per minute, approximately between 14293-215440 S-1
By comparing the rotational speed, it can be seen that this is an important factor in milk crushing and grinding, which is equivalent to 2-3 times the former compared to the latter

2、 Colloidal grinding head and spacing:
SID colloid millSix different module heads can be selected to achieve multiple functions, such as three-stage emulsification module, ultra high speed module, XMD colloid module, XMD colloid module, batch powder liquid mixing module, and continuous powder liquid mixing module.
Adjustable spacing, capable of processing materials with small particle sizes ranging from 1-10 microns
Domestic colloid millThere is only one type of module head with limited particle size and fineness. It is difficult to achieve particle sizes below 100 microns and has poor repeatability

3、 Mechanical seal:
SID colloid millDouble mechanical seals, easy to clean, reduce leakage, and can operate continuously for 24 hours
Domestic colloid millSingle mechanical seal or shaft seal has a high leakage failure rate, and the product leaks into the motor, causing the motor to burn out

4、 Cleaning:
SID colloid millVertical, belt driven, easy to maintain, can effectively protect the motor and gearbox, prevent damage, comply with fluid flow principles, have CIP/SIP online cleaning and online sterilization functions, no need to disassemble, machine design has no dead corners, vertical structure conforms to fluid principles, cleaning is simpler
Domestic colloid millHorizontal or vertical (motor integrated), the bearing part is subjected to high stress, easy to damage, and maintenance is complex,
Usually, it is necessary to disassemble the machine for cleaning

Features of XM2000 series:
① The fixed rotor is made into a circular cone shape, with three-level sawtooth protrusions and grooves with increasing precision. The stator can be infinitely adjusted to the desired distance between it and the rotor.
②The depth of the tooth row: from 2.7mm at the beginning to 0.7mm at the end, the range is relatively large, and the larger the range, the wider the particle size of the processed material.
③ The structure of the groove is inclined teeth, and the groove depth of each grinding head is different, and the volume of the flow channel of the inclined teeth is from top to bottom.

The main uses of high shear colloid mill are:
High shear colloid millSuitable for ultrafine grinding of wet materials in the pharmaceutical, food, chemical, and other industries, capable of crushing, emulsifying, homogenizing, and mixing various semi wet and emulsion substances. The main technical indicators have reached similar levels abroadThe advanced level of the product.

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.
