The core value of thermal conductive sheet materials - efficient heat dissipation - relies entirely on the uniformity of mixing between thermal conductive fillers (graphene, alumina, boron nitride, etc.) and substrates (silicone, rubber, resin). Traditional mixing equipment often faces production bottlenecks in industries such as new energy, electronics, and industry due to high thermal resistance and unstable heat dissipation caused by agglomeration of thermal conductive fillers, uneven color, and residual bubbles. The SMIDA
planetary centrifugal mixer is designed specifically to solve the pain points of mixing thermal conductive sheet materials, achieving global homogenization and consistent color, and assisting in the mass production of high-performance thermal conductive sheets.
1、 Mixing of Thermal Conductive Sheet Materials: Differences in Effect between Traditional Equipment and SMIDA
In response to the characteristics of "high viscosity matrix+easily agglomerated filler" in thermal conductive sheet materials, SMIDA has completely solved the traditional mixing defects through the "planetary mixing+vacuum defoaming" technology, and the effect comparison is intuitive:
After traditional mixing, the thermal conductive filler aggregates into blocks, forming a "local insulation zone" with large fluctuations in thermal conductivity; The colloidal color is mottled and the appearance defect rate exceeds 20%; Internal bubbles block the heat conduction path, causing a sudden drop in heat dissipation efficiency and unable to meet the needs of high-power devices.
After SMIDA stirring, the thermal conductive filler is uniformly dispersed in the matrix without any agglomerated particles, achieving "global homogenization of thermal conductive sheet material"; The color consistency has reached a level that is indistinguishable to the naked eye, and the appearance qualification rate has been increased to over 98%; There are no visible bubbles throughout the entire process, with stable thermal resistance and fully compliant thermal conductivity, making it suitable for harsh heat dissipation scenarios.
2、 Core application areas of thermal conductive sheet materials (covering high-frequency search scenarios)
SMIDA mixer deeply matches the production needs of thermal conductive sheets in different industries, solving the pain points of heat dissipation in segmented fields and covering mainstream application scenarios:
1. New energy vehicle power battery field
Adapt to the requirements of "hybrid equipment for thermal conductive sheets of power batteries" and "stirring solution for thermal conductive pads of lithium batteries", used for the production of thermal conductive pads for lithium battery packs and thermal conductive silicone sheets between battery cells. After mixing, the thermal conductive filler is evenly distributed with stable thermal conductivity, which can quickly dissipate the heat of battery charging and discharging, avoid safety hazards caused by local overheating, and help meet the dual needs of "long range+high safety" of new energy vehicles, in line with the "production standards for new energy thermal conductive sheets".
2. In the field of consumer electronics
Targeting the requirements of "CPU thermal conductive silicone sheet hybrid", "notebook heat dissipation thermal conductive sheet device", and "mobile phone core component thermal conductive sheet mixing", CPU/GPU thermal conductive sheets are used for smartphones and laptops. After mixing, the material thickness is uniform, and there are no gaps in the electronic components. The heat dissipation efficiency is improved by more than 30%, solving the problem of "overheating and frequency reduction" in equipment and adapting to the trend of "lightweight+high heat dissipation" in consumer electronics.
3. Industrial equipment field
Suitable for scenarios such as "mixed thermal pads for industrial frequency converters", "thermal pad equipment for server cabinets", and "mixed solutions for industrial grade thermal pads", used for the production of thermal pads for frequency converters, servers, and charging stations. The stirred thermal conductive sheet has excellent high and low temperature resistance, and the uniformity of thermal conductivity ensures temperature balance among various components of industrial equipment, extending the service life of the equipment by more than 50% and reducing maintenance costs.
4. LED lighting field
In response to the demand for "mixed heat dissipation and thermal conductivity sheets for LED lamps" and "high-power LED thermal conductivity sheet equipment", heat dissipation and thermal conductivity sheets are used for high-power LED chips. The heat conductive sheet after mixing is closely attached to the heat dissipation structure of the lamp, quickly exporting the working heat of the chip, avoiding the phenomenon of "light decay", extending the service life of the lamp to more than 50000 hours, and meeting the long-term stable needs of commercial and industrial lighting.
3、 Highlights of exclusive mixing design for thermal conductive sheet materials
PLC control: Suitable for different forms of thermal conductive fillers such as graphene (flakes) and alumina (particles), adapting different parameters to avoid disorderly packing and blocking of thermal pathways, and meeting the requirements of "mixing equipment for different thermal conductive fillers".
Vacuum collaborative defoaming system: Simultaneously vacuuming during mixing, directly breaking down the "wrapped small bubbles" in the thermal conductive sheet material without the need for secondary defoaming, shortening the production cycle, and meeting the core requirements of "bubble free thermal conductive sheet mixer".
Temperature controlled mixing mode: Based on the viscosity characteristics of the thermal conductive substrate (silicone/resin), adjust the revolution/rotation speed to avoid excessive substrate temperature. The temperature control system ensures sufficient mixing in low-temperature environments and is suitable for "multi environment thermal conductive film mixing equipment" scenarios.
