Organic / Inorganic hybrid nanoparticle, supercritical hydrothermal synthesis Momicho series.

Continuous hybrid synthesis which was difficult to make by conventional process.

[NEDO PROJECT] Realizing 10 t/year production

Making particle dispersible in resin by modifying the surface of the thermal conductive filler.

The result of NEDO project [Super hybrid material technology development 2007-2011]
ITEC Co. has developed this system, as a member of the research of JCII (Japan Chemical Innovation and Inspection Institute), jointly with Professor Adschiri of Tohoku University.

Feature of Momicho giga

Momicho giga is a production system for the super hybrid material which is a key for the material processing, for heat dissipation sheet, resin print circuit board,
packaging material and IC sealing material. The surface modification makes the filler dispersible in the resin without damaging the original feature of the resin.For example the surface modification makes the BN and alumina particles more dispersible thus it makes easy mixing and increase the molderbility and reduce void and makes the heat transfer much better.

• 1.Possible to make high degree of crystallinity of organic / Inorganic particles
• 2.Automatic processing is possible including material supply,reaction, collection, concentration and separation.
• 3.Operation and data administrations are prosecuted by LCD touch panel
• 4.High energy saving is achieved by utilizing high efficiency heat exchanger (More than 70% heat exchange).

Supply unit

• 1.Possible to feed slurry / viscos liquid stably
      Possible to feed highly concentrated slurry (35 wt%).
• 2. Easy to flush the pipe line at material change (Auto flushing).
      Possible to flush the line automatically before and after processing.
• 3.Easy disassemble cleaning
      Disassemble cleaning is easy, since the cylinders are designed for simple disassembling.
• 4. Preventing precipitation by stirring
      Specially designed stirrer is equipped inside bottom of the cylinder.
      Thus the slurry is fed homogeneously without precipitating.
• 5. Continuous / high pressure discharge without pulsation
      No spike occurs at cylinder alternation, since stand-by cylinder has been prepared at high pressure, before the alternation.

Reaction unit

• 1.Rapid heating by high functional heater
      Rapid heating is possible by development of super dense heater.
      Possible to heat us to 600℃(Optional heater required)Capacity can be increased by numbering.
• 2.High efficiency is achieved by heat exchange
      High heat recycle is achieved by special heat exchanger for continuous process.
• 3.Easy parameter change and precise control
      Operation parameters, such as pressure, temperature and process time (Reaction coil to
      be changed) are easy to change without losing precise control.
• 4. Easy maintenance
      The reaction coil, reheat coil (including re-heater)and SCW heater
       (optional) are installed on the same ceiling plate. It is easy to take out with
      ceiling plate as one unit for maintenance.

Collection unit

• 1. Stable pressure adjustment
      No plugging or wearing occurs, since the pressure is controlled at water side of the cylinder.
      The product can be collected at high pressure.
• 2.Continuous / high pressure collection without pulsation
      No spike occurs at cylinder alternation, since stand-by cylinder has been prepared at
      high pressure, before the alternation.
• 3. High concentration slurry can be collected
      High concentration slurry can be collected at steadily at high pressure, continuously.
• 4. Easy disassemble cleaning
      Disassemble cleaning is easy, since the cylinders are designed for simple disassembling.

Washing and drying unit

• 1. Continuous operation is possible
• 2. Selection of A basin system, an oil system possible
• 3. Whole amount filtration system is applied
      Energy saving and Separation efficiency are improved.
• 4. Washing solvent (ethanol) is recycled.
      The ethanol, which is used for washing, is recycled by recycler for reuse.
• 5. Waste heat is reused
      The heat is required at drying process is a recycled waste heat from the reaction unit.

Control system

• 1.Safety first electrical design
      In order to make the system safely, circuits are separated unit by nit,
      which makes the ground fault easier. All the units are linked by
      Ethernet for remote control (future arrangement).
• 2.Legible screen and easy operation
      15” screen is equipped for the LCD. Status of the system is
      very easy to see, since all the active devices and lines are lit on the LCD screen.
• 3. Adoption of icon touch system
      Device is operated with touching the icon on the LCD screen.
• 4. Smart data logging
      Status of all the devices and trends can be monitored.

Heat balance sheet

The heat generated at the reaction unit is efficiently recovered by two step of heat exchangers.

• 1.High temperature heat recovery / Low temperature heat recovery
      The high temperature waste heat recovered at the
      product cooling unit will be used at as heater for purified water.
      The medium temperature waste heat coming out from the high temperature heat exchange     will be used at surface modifier heating and raw material heating. (total 55% or over)
• 2.Low temperature heat recovery
      The waste heat coming out from the medium heat exchanger will
      be used for product concentration and drying as cascade heat. (total 15% or over)
