Description

Technical Field [0001] The present invention relates to a rotor-rotor type dispersing and emulsifying apparatus, and more particularly, to an impeller-

The present invention relates to a method of installing and operating an impeller structure system for a rotor-rotor type dispersion and emulsification apparatus, and more particularly, to an impeller structure including a first rotor and a second rotor, Are driven in opposite rotational directions by respective drive motors, and each object to be mixed passes sequentially through the multi-stage impeller parts one-pass at a time, thereby greatly shortening the entire working time for dispersion emulsification processing, The present invention relates to a method of installing and operating an impeller structure system of a rotor-rotor type dispersing and emulsifying apparatus in which uniformity of particle size is improved by finely shearing (cutting) a material (object material)

(Materials) and other materials (substances) selected in the basic material industry in each technical field including food, cosmetics, ink, paint, adhesive, coating agent, fine chemical, medicine, nano- Is used as a base material.

The materials to be mixed as the base material have a significant influence on the quality of the finished product due to the uniformity and fineness of mixing by the dispersing and emulsifying process of each particle, and various dispersing and emulsifying apparatuses suitable for these demands have been developed and used.

Dispersion (homogenization) is a method in which a solid containing a powder is mixed homogeneously in a liquid or a liquid other than the liquid, so that the size of the particle is reduced and uniformly present in a stable state. "And" emulsion "that mixes the" first liquid "and the" second liquid "in which the interface exists.

In other words, dispersion and homogenization means making the particle size small. To make the particle size small, it is necessary to apply the strong energy (driving force) to the material to crush or shear or cut the particle size. Small.

Conventional dispersing and emulsifying apparatus is a high-pressure homogenizer, which converts the kinetic energy of a jet into shear energy by converting the pressure (energy) into a jet to collide or invert the material (material, material) So that dispersion and emulsification are performed. In this method, the pressure and the velocity gradient exist in the reactant (material to be mixed) in the process, so that the air dissolved in the contents generates bubbles, the particles mixed by the bubbles become uneven, And the time required for emulsification is long, resulting in a problem of deteriorating efficiency.

On the other hand, we will look more closely at dispersion versus mixing.

Dispersion is a state in which particles of a substance are made very small and particles and particles are stably and uniformly distributed to each other, and mixing is a simple mutual mixing of a substance (material) and a material (material) unlike dispersion.

When the propeller and impeller are rotated using the mixing equipment such as overhead, the two materials are mixed by the rotation of the impeller blades. This is a simple mixing process in which the particle size is reduced, that is, the homogenization process is omitted.

The unit indicating the degree of particle size reduction in the mixing process is the "shearing force" and the difference between mixing and dispersing is very large as follows.

On the other hand, the viscosity of the object to be dispersed is the most problematic in dispersion performance. Even when the viscosity is higher than about 2,000 mPas, the dispersion efficiency is lowered. When the viscosity is 5000 mPas, dispersion using a general apparatus is not achieved.

Viscous materials increase the rotational speed of the impeller to increase the tip speed of the rotor and provide a fence around the impeller to reduce the numerical value of the clearance or gap The shearing force must be increased.

1 is a functional structural diagram illustrating an ultrasonic dispersion and emulsification method according to an embodiment of the prior art.

As described with reference to the attached drawings, when the ultrasound at 20 kHz is emitted into a solution with a strong intensity, numerous microcavities are generated in the solution. When the microcavities are broken, the high temperature and pressure And the particles of the object to be dispersed are broken up very finely (finely) by the shock wave energy. The dispersing and emulsifying method using ultrasonic waves is very effective and has the advantage of enabling nano-sized dispersion and emulsification. However, dispersing and emulsifying the viscous material takes a long time and has limitations on uniformity and homogeneity of mixing.

2 is a functional structural diagram illustrating a rotor-stator type dispersion and emulsification method according to an embodiment of the prior art.

Referring to the accompanying drawings, particles of a target material (material) passing between a rotor and a stator by a strong shearing force, which is composed of a fixed stator and a rotating rotor and is generated by strong rotational energy of the rotor, It is a rotor-stator system in which dispersive emulsification is performed.

The tip speed of the rotor, which rotates at a speed of tens of thousands of rpm by a motor with a strong rotating force, reaches about 20 m / sec, which allows the dispersed object (material) to pass between the rotor- . At this time, the clearance between the rotor and the stator, that is, the gap of the rotor-stator is about 0.1 mm, which forms a very small gap. When the object to be dispersed passes through the gap between the narrow rotor / stator at a strong rotation speed, a shearing effect occurs and the particle size shear or shear instantaneously to a very small extent.

This rotor-stator method was developed decades ago, and for a long time, Germany's IKA had the patent right, and now the patent has expired and its method is already open.

The advantage of this method is that it can disperse high viscosity and has good dispersing and emulsifying effect from the viewpoint of process convenience. Currently, it is the mainstream of dispersing and emulsifying apparatus based on most rotor-stator methods and there are differences in performance. However, .

However, there is still a problem that dispersion of fine particles at the level of nanoparticles having a small particle size to be mixed is difficult to be mixed and takes a long time to process.

Therefore, rotor-rotor method is adopted instead of the rotor-stator method to improve the uniformity of particles by homogenizing the particles by increasing the shear force, and the processing time is improved even in the case of fine particle dispersion oiling at the nanoparticle level Need to develop.

- High cost if you scale up your existing mixer to more than laboratory.
- The larger the treatment capacity, the more the area of agitation, the lower the quality, the longer the treatment time is required (more than 8 hours)
- Low quality and low yield due to backward process - Dispersion and emulsification with high uniformity by rotor-rotor method.
- Large capacity to small capacity can be processed.
- Reduction of work time by flow-type one-pass process from pre-mixing to input and discharge of raw materials.
- The residence time of dispersing reactor is greatly reduced and no deterioration due to heat generation occurs during dispersion emulsification.

<Ink Mixing / Manufacturing Process>

Inks are manufactured in a conventional manner, and are complicated processes in which materials are mixed, dissolver, 3-roll mill and bead mill are dispersed, varnish is added, additives are added, and dissolving is performed again.

Rotor-Rotor Dispersion Emulsification Apparatus When the impeller structure system 100 is applied to a process, it is possible to shorten the process time by supplying high shear energy in material mixing and dissolver process.

<Additive Mixing Step of Foaming Adiabatic Agent>

A very small amount of the additive for foaming the insulating material in the step of manufacturing a foam insulating material is added. It is relatively difficult to continuously mix the additive added in a small amount in the production stage.

Application of the rotor-rotor type dispersing and emulsifying apparatus impeller structure system (100) to the process enables a continuous production with a constant quality because a small amount of additive and heat insulating material are respectively injected and dispersed and emulsified in one pass. Even in adiabatic performance, an improved synergistic effect of 30% can be obtained.

<Silicon GUM Blending>

Silicon used for adhesives and films has recently been expanding its demand to be used for special protective films for smart phones. However, in the processing process at the production site where the silicon raw material is dissolved from the GUM state, the storage tank is heated to a temperature of 130 ° C. Since it must be cooled after 48 hours of operation, it takes a lot of production time and cost.

Rotor-Rotor Dispersion Emulsification Apparatus When the impeller structure system 100 is applied to such a process, the process can be completed in about 5 hours by the high shear force of the rotor-rotor, and mass production is possible.

But it has a disadvantage that it is difficult to utilize it in real life because it is complicated in production process and difficult to mass-produce.

Rotor-Rotor Dispersion Emulsification Apparatus Using the impeller structure system (100), it is possible to mass-produce with the technology utilizing the high shear force of the rotor-rotor.

<Carbon black>

Industrial carbon black is used in a variety of applications such as printing ink, toner, coating, plastic, paper and construction, and is recently used for exterior coating of smart phones. Carbon black is very difficult to disperse as compared with other pigments, and since the components are carbon and the carbon is coagulated due to the characteristics of carbon, it does not fall off well, so that it is difficult to produce uniform quality products.

Rotor-rotor type dispersing and emulsifying apparatus Using the impeller structure system (100), the high shear force of the rotor-rotor is utilized to handle the dispersion emulsification of carbon, so that the product can be mass-produced in a uniform quality.

<Metal Paste Dispersion>

Nanometer metal paste used for chip capacitor, which is a core part of smart phone, is very important to disperse and it causes electrical failure if nano metal paste is not dispersed well.

Chip capacitors are core components that are used extensively in electronic devices and automobiles, as well as in mobile devices such as smart phones and tablet PCs, and serve to control power supply to be supplied in a timely manner as needed for each component.

Rotor-Rotor Dispersion Emulsification Apparatus The use of the impeller structure system (100) makes it possible to disperse and emulsify the nanometer metal paste by the high shear force of the rotor-rotor, thereby reducing electrical failure and mass-producing chip capacitors with uniform quality.

<Dispersion of medical polymer filler and collagen>

The filler which is frequently used in cosmetic molding means that it is filled in English. In the field of cosmetic molding, it refers to a complementary material that hides wrinkles and scars by injecting or inserting into the skin.

Currently, the filler field is divided into a product using a hyaluronic acid component, which is a biomaterial existing on the skin in the human body, and a product using a biocompatible polymer component.

Unlike hyaluronic acid products, which use biocompatible polymers for 6 months to 1 year, they are effective for more than 2 years through a single procedure. And it is known that it has a natural effect like a real organization.

In the domestic beauty sector, the filler market is about 100 billion won, and the global market is known as a large market with more than 2 trillion won, and it is expected to continue to grow due to aging population and increasing interest in beauty.

Collagen, which is a biocompatible polymer, has a problem in that it is difficult to stir and mass-produce because of its high viscosity, and thus the raw material is very expensive.

Rotor-Rotor Dispersion Emulsification Apparatus The impeller structure system (100) makes it possible to mass-produce the filler by utilizing the high shear force of the rotor-rotor and the ONE-PASS type.

&Lt; Secondary Battery Manufacturing >
