Conductive resistance material high shear disperser

Resistance material dispersing machine，Slurry disperser, resistance slurry disperser, is a slurry used to manufacture thick film resistors with precious metals as the conductive phase. Mainly used as thick film resistors, resistor networks, hybrid integrated circuits, and resistors and electrodes for special purposes.

The production equipment for dispersed conductive paste in traditional battery paste is an intermittent planetary agitator mixing device, which has its relative defects, manifested in:
1. Batch dispersion process, long mixing and dispersion time, high energy consumption.
2. Low mixing efficiency, weak shear force, uneven energy input, wide particle size distribution of the resulting slurry, and unstable product quality.
The 3-electrode powder material is added from the top of the planetary mixer, and dust is prone to fly and float. More importantly, powder is prone to agglomeration when mixed with liquid phase.
4. Materials are prone to residue on the lid, walls, and blades of the planetary mixer, making cleaning operations difficult.
5. Air is easily stored in the dispersion mixing tank, and the generation of bubbles affects the dispersion effect.
6. Batch production is limited due to the batch process, and the production line occupies a large area of land, resulting in high maintenance costs.

The conductive phase includes noble metal conductive components with high diffusion coefficient and low resistance coefficient, as well as platinum group metals or their compound resistive components with high resistance coefficient. Some now use metals, their sulfides, and polymer organic compounds with higher chemical stability as conductive phases. Divided into silver palladium slurry, ruthenium dioxide slurry, ruthenate slurry, and iridium and rhodium slurry. Among them, ruthenium based slurry is used. They have good chemical stability, thermal stability, and moisture resistance, high precision and wide range of resistance values, small temperature coefficient of resistance, high resistance and low noise, and good compatibility with silver based conduction bands. If precious metal powder is added, the resistance range can be widened. Adding MnO2 and CuO can adjust the temperature coefficient of resistance, CdO can improve moisture resistance stability, and Ta2O5 can obtain high-performance high resistance slurries. A mixture powder of precious metals (or their compounds), borosilicate lead glass, and additives is prepared into a slurry using an organic carrier. Mainly used as thick film resistors, resistor networks, hybrid integrated circuits, and resistors and electrodes for special purposes.

Resistance material disperser, resistance slurry high shear disperserThe high-speed ultrafine dispersion mixer is suitable for the process requirements of one-time production and processing with high viscosity. The special multi-layer stator and rotor structure has significant ultrafine dispersion and crushing performance. When the material is automatically sucked into the working chamber from the equipment inlet, it undergoes hundreds or thousands of strong shearing, impact, grinding, and cavity effects through multiple shearing surfaces, achieving sufficient dispersion, crushing, and refinement of the material. Compared with traditional decentralized equipment, it has the advantages of simple structure, fast completion of dispersed and refined processing, significant effect, low energy consumption, and easy maintenance.

High rotational speed and shear rate are important for obtaining ultrafine suspensions. According to some industry specific requirements, Xide Company has developed the XRS2000 ultra high speed shearing emulsifier machine based on the XR2000 series. Its shear rate can exceed 200.00 rpm, and the rotor speed can reach 66m/s. Within this speed range, turbulence caused by shear forces combined with specially developed motors can reduce the particle size range to the nanometer level. The shear force is stronger, and the particle size distribution of lotion is narrower. Due to its high energy density, it can achieve the particle size of a regular high-pressure homogenizer at a pressure of 400BAR without the need for other auxiliary dispersing equipment

Pilot testing refers to the testing of a product before it is officially put into productionThe intermediate stage of a pilot scale experiment is a small-scale trial of a product before mass production. When a company is determining an item, oneTo conduct laboratory experiments; The second step is "small-scale testing", which means scaling up based on the laboratory results; The third step is the 'pilot test', which involves further scaling up based on the results of the small-scale test. After successful pilot testing, mass production can basically begin. The corresponding pilot equipment is specially designed for the characteristics of pilot testing，It can help users obtain complete technical solutions close to industrial level, and can also be used as small-scale production equipment for small batch production.
The drawbacks of traditional small-scale emulsifiers：
Traditional batch emulsifiers used for research and development may achieve the required results, but the equipment parameters explored are completely unusable. Batch emulsifiers cannot be linearly scaled up, so later industrial production needs to re explore parameters, which can lead to low efficiency and high risks.

The three-stage high shear dispersion machine is mainly used for the production of micro lotion and ultra-fine suspension lotion. Since three groups of dispersion heads (stator+rotor) in the working chamber work at the same time, after high shearing, the lotion drops are more delicate and the particle size distribution is narrower, so the stability of the generated mixed liquid is better. The three sets of dispersing heads are easy to replace and suitable for different process applications. The different models of machines in this series have the same line speed and shear rate, making it very easy to scale up production. It also meets the CIP/SIP cleaning standards and is suitable for food and pharmaceutical production.

High rotational speed and shear rate are important for obtaining ultrafine suspension lotion. According to some industry specific requirements, its shear rate can exceed 15000rpm, and the rotor speed can reach 44m/s. Within this speed range, turbulence caused by shear forces combined with specially developed motors can reduce the particle size range to the nanometer level. The shear force is stronger, and the particle size distribution of lotion is narrower.
