Description

탄소나노튜브 분산 통합 장치Carbon nanotube dispersion and integration device
본 발명은 탄소나노튜브 분산 통합 장치에 관한 것으로, 보다 상세하게는 탄소나노튜브에 손상을 주지 않으면서 빠르게 탄소나노튜브 다발을 분산시킬 수 있는 탄소나노튜브 분산 통합 장치에 관한 것이다. The present invention relates to a carbon nanotube dispersion and integration device, and more particularly, to a carbon nanotube dispersion integration device capable of rapidly dispersing a carbon nanotube bundle without damaging the carbon nanotubes.
리튬 이온 전지(Lithium Ion Battery)는 양극, 음극 별 활물질 분체를 용액에 분산시킨 슬러리를 만들고, 이를 극판에 코팅하여 건조한 후 분리막을 사이에 두고 제조한 양극, 음극판을 겹친 다음, 용기에 넣고 전해액을 주입하는 공정으로 만들어진다. 이 슬러리를 만들 때 활물질 분체 사이에서 전기를 원활하게 흘려 주는 역할을 하는 도전제를 섞어서 제조하면 전지의 성능을 개선할 수 있다.Lithium ion battery (Lithium Ion Battery) makes a slurry in which the active material powder for each positive electrode and negative electrode is dispersed in a solution, coats it on an electrode plate and dries it. It is made by the injection process. When making this slurry, the performance of the battery can be improved by mixing a conductive agent that smoothly flows electricity between the active material powders.
탄소나노튜브(Carbon Nano Tube, CNT)는 직경 대비 길이가 수 천 배에 이르는 선 형태이고, 전기 전도도가 구리와 비슷하고, 도전제로서의 기능이 뛰어나다. 탄소나노튜브를 사용하게 되면 기존 도전제를 사용했을 때 보다 전지 안에 공간이 확보되며 이 남은 공간에 활물질을 더 넣어서 전지 용량을 늘릴 수 있다. Carbon nanotubes (CNTs) are in the form of lines with a length of several thousand times the diameter, electrical conductivity similar to copper, and have an excellent function as a conductive agent. When carbon nanotubes are used, more space is secured in the battery than when conventional conductive materials are used, and the battery capacity can be increased by adding more active materials to the remaining space.
그러나 탄소나노튜브는 여러 가닥이 다발로 얽혀 있으므로, 이를 사용하기 위해서는 용액에 고루 분산시켜야 한다. 종래 기술에서 사용되고 있는 탄소나노튜브 분산 방법은 초음파나 비즈밀을 이용한 물리적인 분산 방법과, 계면 활성제 등을 이용한 화학적인 분산 방법이 있다. However, since several strands of carbon nanotubes are entangled in bundles, they must be evenly dispersed in a solution to use them. The carbon nanotube dispersion method used in the prior art includes a physical dispersion method using ultrasonic waves or a bead mill, and a chemical dispersion method using a surfactant or the like.
물리적인 방법 중 초음파 분산 방법은 NMP(N-Methyl-2-Pyrrolidone, N-메틸피롤리돈)나 DMF(Dimethylformamide) 등의 유기 용매에 탄소나노튜브 분말을 넣은 후에 초음파를 가하여 분산하는 방법이나, 이 방법은 용액의 안정성이 떨어지는 문제점이 있다. Among the physical methods, the ultrasonic dispersion method is a method of dispersing by adding ultrasonic waves after putting carbon nanotube powder in an organic solvent such as NMP (N-Methyl-2-Pyrrolidone, N-methylpyrrolidone) or DMF (Dimethylformamide), This method has a problem in that the stability of the solution is poor.
한편 물리적인 방법 중 비즈밀이나 고전단 분산기 등을 이용한 방법은 탄소나노튜브의 가닥을 끊어서 길이가 짧아지는 문제점이 있다.On the other hand, among the physical methods, the method using a bead mill or a high shear disperser has a problem in that the length of the carbon nanotube is shortened by breaking the strand.
화학적인 방법은 전지에 필요한 성분 이외의 화학물질을 첨부하고 이를 제거하는 추가 공정을 필요로 하는 문제점이 있다. 따라서 이를 개선할 필요성이 요청된다. The chemical method has a problem in that it requires an additional process for adding and removing chemicals other than the components required for the battery. Therefore, there is a need to improve it.

도 1 내지 도 6을 참조하면, 본 발명의 일 실시예에 따른 탄소나노튜브 분산 장치(1)는 용액수용부(100)와 초음파 진동자부(200)를 포함한다. 1 to 6 , the carbon nanotube dispersing apparatus 1 according to an embodiment of the present invention includes a solution receiving unit 100 and an ultrasonic vibrator 200 .
용액수용부(100)는 CNT 용액(10)을 수용하는 것이다. CNT 용액(10)은 CNT(Carbon Nano Tube, 탄소나노튜브)를 포함하는 용액이다. 용액수용부(100)는 용액수용몸체부(110), 유동관부(120), 나선가이드부(130)를 포함한다. The solution receiving unit 100 is to accommodate the CNT solution (10). The CNT solution 10 is a solution containing CNT (Carbon Nano Tube, carbon nano tube). The solution accommodating part 100 includes a solution accommodating body part 110 , a flow pipe part 120 , and a spiral guide part 130 .
용액수용몸체부(110)는 일면(도 1 기준 우측)이 평면으로 형성되는 반원기둥 형상으로 형성된다. 유동관부(120)는 용액수용몸체부(110)의 내부에 관통 형성되는 것으로, CNT 용액(10)이 유동되는 경로를 제공한다. 유동관부(120)는 일측(도 1 기준 상측)이 입구부(121)이고, 타측(도 1 기준 하측)이 출구부(123)이다. The solution receiving body 110 is formed in a semi-cylindrical shape in which one surface (the right side of FIG. 1 ) is formed as a flat surface. The flow pipe part 120 is formed through the inside of the solution receiving body part 110, and provides a path through which the CNT solution 10 flows. One side (upper side in FIG. 1 ) of the flow pipe part 120 is the inlet part 121 , and the other side (the lower side in FIG. 1 ) is the outlet part 123 .
설정 내경(D)을 구비하는 유동관부(120)에서 유동되는 CNT 용액(10)을 층류로 형성하기 위해, 설정된 속도로 CNT 용액(10)이 유동되면, CNT 용액(10) 안의 개별 CNT는 유동관부(120)의 길이 방향으로 배열되면서 유동관부(120)로 흘러가게 된다.In order to form the CNT solution 10 flowing in the flow tube part 120 having a set inner diameter D in a laminar flow, when the CNT solution 10 flows at a set speed, the individual CNTs in the CNT solution 10 flow While being arranged in the longitudinal direction of the pipe part 120, it flows into the flow pipe part 120 .
CNT 용액(10)에서 구형 알갱이 모양의 덩어리부(15)를 분리할 때는 CNT 용액(10)에 강한 난류를 줄수록 유리하지만, 본 발명에서는 길다란 선형구조를 가지는 CNT를 CNT 용액(10)의 흐름에 평행하게 배치하기 위하여 층류를 만들어 주는 것이다. 층류를 만들어서 CNT 가닥을 CNT 용액(10)의 유동에 평행하게 배치하면, 난류에 의한 전단력에 의해 CNT 가닥이 손상되는 현상을 방지할 수 있다.When separating the spherical granular mass portion 15 from the CNT solution 10, it is advantageous as strong turbulence is given to the CNT solution 10. It creates a laminar flow in order to arrange it parallel to the If the CNT strands are arranged parallel to the flow of the CNT solution 10 by creating a laminar flow, it is possible to prevent the CNT strands from being damaged by the shear force caused by the turbulence.
유동관부(120)를 흐르는 CNT 용액(10)이 층류(Laminar Flow)인지 난류(Turbulent Flow)인지 알아보기 위해서는 다음 수식에서 레이놀즈 수(Reynolds Number, Re)를 계산한다.In order to determine whether the CNT solution 10 flowing through the flow pipe unit 120 is a laminar flow or a turbulent flow, the Reynolds number (Re) is calculated from the following equation.
[수식][formula]
Figure PCTKR2021004816-appb-img-000001
Figure PCTKR2021004816-appb-img-000001
여기에서, μ는 CNT 용액(10)의 점성계수(Viscosity), V는 CNT 용액(10)의 속도(Velocity), D는 유동관부(10)의 내경(Inner Diameter), ρ는 CNT 용액(10)의 밀도(Density)이다.Here, μ is the viscosity coefficient of the CNT solution 10, V is the velocity of the CNT solution 10, D is the inner diameter of the flow pipe 10, ρ is the CNT solution 10 ) is the density of
유동관부(120) 안에서 흐르는 CNT 용액(10)의 경우, 위 수식에 의해 계산된 레이놀즈 수(Re)가 약 2,100 이하일 때 층류를 형성하고, 4,000 이상에서는 난류를 형성한다. Re가 2,000 ~ 4,000 사이는 천이 영역(T/ransition Zone)이라 부른다. 따라서 사용하는 CNT 용액(10)의 점성계수와 밀도를 알면 관로의 직경과 유체의 흐르는 속도를 조절하여 층류 유동을 얻을 수 있다.In the case of the CNT solution 10 flowing in the flow pipe part 120, when the Reynolds number (Re) calculated by the above equation is about 2,100 or less, laminar flow is formed, and when it is 4,000 or more, turbulence is formed. A range between 2,000 and 4,000 Re is called a transition zone (T/ransition zone). Therefore, if the viscosity coefficient and density of the CNT solution 10 used are known, the laminar flow can be obtained by controlling the diameter of the pipe and the flow rate of the fluid.
본 발명에서 유동관부(120)의 내경(D)은 레이놀즈 수(Re)는 4,000 이하가 나오도록 설정한다. 따라서 유동관부(120)를 흐르는 CNT 용액(10)은 천이 영역 내지 층류로 형성된다. In the present invention, the inner diameter (D) of the flow pipe part 120 is set so that the Reynolds number (Re) is 4,000 or less. Therefore, the CNT solution 10 flowing through the flow pipe unit 120 is formed in a transition region or laminar flow.
나선가이드부(130)는 유동관부(120)의 내벽에 형성되어 CNT 용액(10)이 나선형으로 유동되게 가이드한다. 나선가이드부(130)는 유동관부(120)의 내벽에 적어도 2회 이상 회전 방향이 변경되도록 왼나선형과 오른나선형이 교호되게 형성된다. The spiral guide unit 130 is formed on the inner wall of the flow pipe unit 120 to guide the CNT solution 10 to flow in a spiral. The spiral guide unit 130 is alternately formed with a left spiral type and a right spiral type on the inner wall of the flow pipe unit 120 so that the rotation direction is changed at least twice or more.
나선가이드부(130)는 유동관부(120)의 내벽에 오목한 홈 또는 돌기로 돌출 형성된다. 나선가이드부(130)는 유동관부(120)의 내벽에 홈이나 돌기로 나선형으로 형성되어, 총신 내부를 진행하는 총알이 총신 내부에 마련된 강선에 의하여 회전하듯이 CNT 용액(10)이 유동관부(120)의 내벽을 흘러가면서 회전력을 받게 된다.The spiral guide unit 130 is formed to protrude into a concave groove or protrusion on the inner wall of the flow pipe unit 120 . The spiral guide part 130 is formed in a spiral shape with grooves or protrusions on the inner wall of the flow pipe part 120, so that the CNT solution 10 is the flow pipe part ( 120) as it flows through the inner wall and receives rotational force.
유동관부(120)의 내벽에 형성되는 나선가이드부(130)는 설정 길이마다 회전 방향을 바꾸도록, 왼나선형과 오른나선형이 교호되게 형성된다. 나선가이드부(130)는 제1나선가이드부(131), 제2나선가이드부(133), 제3나선가이드부(135)를 포함한다. The spiral guide unit 130 formed on the inner wall of the flow pipe unit 120 is alternately formed in a left spiral type and a right spiral type to change the rotation direction for each set length. The spiral guide unit 130 includes a first spiral guide unit 131 , a second spiral guide unit 133 , and a third spiral guide unit 135 .
제1나선가이드부(131)는 입구부(121)에서 시작되어 일방향으로 꼬인 나선형(도 1 기준 오른나선형)으로 형성된다. 제2나선가이드부(133)는 제1나선가이드부(131)의 일측(도 1 기준 하측)에서 연장 형성되어 타방향으로 꼬인 나선형(도 1 기준 왼나선형)으로 형성된다. 제3나선가이드부(135)는 제2나선가이드부(133)의 일측(도 1 기준 하측)에서 연장 형성되어 일방향으로 꼬인 나선형(도 1 기준 오른나선형)으로 형성된다. The first spiral guide part 131 is formed in a spiral (right-handed spiral type in FIG. 1 ) that starts from the inlet part 121 and is twisted in one direction. The second spiral guide part 133 is formed to extend from one side (lower side of FIG. 1 ) of the first spiral guide part 131 and is formed in a spiral twisted in the other direction (left spiral type based on FIG. 1 ). The third spiral guide part 135 is formed to extend from one side (lower side of FIG. 1 ) of the second spiral guide part 133 and is formed in a spiral twisted in one direction (right spiral type in FIG. 1 ).
본 발명에서 상술한 제1나선가이드부(131), 제2나선가이드부(133), 제3나선가이드부(135)를 포함하는 나선가이드부(130)는 유동관부(120)에 2회 회전방향이 변경되게 형성된다. 입구부(121)로 들어간 CNT 용액(10)은 제1나선가이드부(131)를 지나변서 시계방향(CW)으로 회전하며 움직이다가, 1번 회전 방향 변화점인 제2나선가이드부(133)를 지나면서 반시계방향(CCW)으로 회전한다. 그러다가 2번 회전 방향 변화점인 제3나선가이드부(135)부터는 다시 시계방향(CW)으로 회전방향이 변하게 된다.In the present invention, the spiral guide portion 130 including the first spiral guide portion 131 , the second spiral guide portion 133 , and the third spiral guide portion 135 is rotated twice in the flow tube portion 120 . direction is changed. The CNT solution 10 entering the inlet 121 passes the first helix guide part 131 and rotates in the clockwise direction (CW), and then the second helix guide part 133 which is the first rotational direction change point. ) and rotates counterclockwise (CCW). Then, from the third spiral guide part 135, which is the second rotation direction change point, the rotation direction is changed again in the clockwise direction (CW).
나선가이드부(130)는 상술한 나선형이 계속적으로 왼나선형과 오른나선형이 교호 형성되어 회전 방향의 변경이 증가될 수 있다. In the spiral guide unit 130 , the above-described spiral is continuously alternately formed in a left spiral type and a right spiral type, so that the change of the rotation direction may be increased.
CNT 용액(10)은 유동관부(120) 내벽에서 나선가이드부(130)를 따라 길게 늘어서서 왼나선형과 오른나선형으로 번갈아 가면서 비틀림을 받게 된다. 따라서 CNT 용액(10)은 손으로 비비는 것과 같이 CNT 다발이 풀어지게 된다. The CNT solution 10 is stretched along the spiral guide unit 130 on the inner wall of the flow pipe unit 120 and is twisted alternately in a left spiral type and a right spiral type. Therefore, the CNT solution 10 is released as a CNT bundle by hand rubbing.
유동관부(120)의 홈 또는 돌기의 단면의 형상이 반구형, 원형, 다각형 중에서 가공의 편이성 등을 고려하여 선택될 수 있다. 유동관부(120)의 내벽에 형성된 홈 또는 돌기는 유동관부(120)를 흐르는 CNT 용액(10)을 회전시킨다.The shape of the cross-section of the groove or protrusion of the flow pipe part 120 may be selected from among hemispherical, circular, and polygonal shapes in consideration of ease of processing and the like. The grooves or protrusions formed on the inner wall of the flow pipe unit 120 rotate the CNT solution 10 flowing through the flow pipe unit 120 .
유동관부(120)에서 나선가이드부(130)를 따라 흐르는 CNT 용액(10)은 난류가 발생되기 직전까지 고속으로 흐르므로, 상술한 회전 방향의 변화는 CNT 용액(10) 안의 CNT 다발에 큰 비틀림 운동 에너지를 가하게 된다.Since the CNT solution 10 flowing from the flow pipe unit 120 along the spiral guide unit 130 flows at a high speed until just before turbulence occurs, the above-described change in the rotation direction causes a large torsion in the CNT bundle in the CNT solution 10 . kinetic energy is applied.
유동관부(120)는 직관부(120a)를 구비한다. 직관부(120a)는 유동관부(120)의 하측에 출구부(123) 측을 향해 직선으로 형성된다. 직관부(120a)는 CNT 용액(10)이 출구부(123) 측을 향해 직선으로 유동되게 가이드한다. 직관부(120a)의 길이는 유동관부(120)의 내경(D)을 기준으로 1D 내지 20D로 이루어지게 형성된다. The flow pipe part 120 includes a straight pipe part 120a. The straight pipe part 120a is formed in a straight line toward the outlet part 123 on the lower side of the flow pipe part 120 . The straight pipe part 120a guides the CNT solution 10 to flow in a straight line toward the outlet part 123 side. The length of the straight pipe part 120a is formed to be 1D to 20D based on the inner diameter D of the flow pipe part 120 .
초음파 진동자부(200)는 용액수용몸체부(110)의 외벽에 장착되고, CNT 용액(10)에 초음파를 제공한다. 초음파 진동자부(200)는 용액수용몸체부(110)의 길이방향을 따라 복수개가 배치된다. The ultrasonic vibrator 200 is mounted on the outer wall of the solution receiving body 110 , and provides ultrasonic waves to the CNT solution 10 . A plurality of ultrasonic vibrator units 200 are disposed along the longitudinal direction of the solution receiving body unit 110 .
초음파 진동자부(200)는 유동관부(120)와 나선가이드부(130)에서 CNT 용액(10)의 회전 방향의 변화로 발생된 비틀림으로도 CNT 가닥 사이의 반데르발스 인력(Van der Waals Force)에 의해 분산되지 않은 CNT의 덩어리부(15)를 분산시킨다. The ultrasonic vibrator 200 is a torsion generated by a change in the rotational direction of the CNT solution 10 in the flow tube part 120 and the spiral guide part 130 as well as the Van der Waals force between the CNT strands. Dispersing the lumps 15 of CNTs that are not dispersed by
나선가이드부(130)를 타고 흐르는 CNT 용액(10)은 시계방향과 반시계방향으로 교번되면서 비틀림 힘을 받게 된다. 이때 초음파 진동자부(200)에 의해 유동관부(120)에 초음파 진동을 CNT 용액(10)이 받게 된다. 이 초음파 진동은 반데르발스 인력으로 뭉쳐 있는 CNT 용액(10)의 CNT 가닥들을 떼어 놓는다.The CNT solution 10 flowing along the spiral guide unit 130 receives a torsion force while alternating in clockwise and counterclockwise directions. At this time, the CNT solution 10 is subjected to ultrasonic vibrations in the flow tube unit 120 by the ultrasonic vibrator unit 200 . This ultrasonic vibration separates the CNT strands of the CNT solution 10 that are agglomerated by van der Waals attraction.
즉, 초음파 진동자부(200)는 유동관부(120)와 나선가이드부(130)의 내부의 층류 흐름에 일직선으로 배치되어 흐르고 있는 CNT 다발들에 뭉쳐 있는 방향의 수직 방향으로 초음파 진동이 가해져서 반데르발스 인력을 이기는 힘을 받아 CNT 가닥과 가닥이 떨어지게 된다. 이때 이 분리된 CNT를 포함하는 CNT 용액(10)가 시계방향과 반시계방향으로 계속 비틀림 힘을 교번으로 받으며 이동하기 때문에 일단 분리된 CNT 가닥은 더욱 멀리 떨어지게 된다.That is, the ultrasonic vibrator part 200 is arranged in a straight line in the laminar flow inside the flow tube part 120 and the spiral guide part 130 and the ultrasonic vibration is applied in the vertical direction in the direction in which the CNT bundles flowing are agglomerated. CNT strands and strands are separated by a force that overcomes the Der Waals attraction. At this time, since the CNT solution 10 containing the separated CNTs continues to move while receiving the torsional force alternately in the clockwise and counterclockwise directions, the CNT strands once separated are further separated.
초음파 진동자부(200)는 초음파 진동자몸체부(210)와 접촉부(230)를 포함한다. 초음파 진동자몸체부(210)는 내부에 초음파 진동 발생장치(미도시)를 수용한다. 접촉부(230)는 초음파 진동자몸체부(210)의 일면(도 1 기준 좌측)이 용액수용몸체부(110)의 외벽에 접촉된다. The ultrasonic vibrator part 200 includes an ultrasonic vibrator body part 210 and a contact part 230 . The ultrasonic vibrator body 210 accommodates an ultrasonic vibration generating device (not shown) therein. In the contact part 230 , one surface (the left side of FIG. 1 ) of the ultrasonic vibrator body part 210 is in contact with the outer wall of the solution receiving body part 110 .
접촉부(230)는 초음파 진동자를 CNT 용액(10)이 흐르는 유동관부(120) 측을 향해 용액수용몸체부(110)의 외벽에 부착될 때, 초음파 진동을 유동관부(120)에만 집중적으로 조사하기 위하여 CNT 용액(10)이 흐르는 방향(도 1 기준 상하방향)으로 좁고 길게 형성된다. When the contact part 230 is attached to the outer wall of the solution receiving body part 110 toward the flow pipe part 120 side through which the CNT solution 10 flows, the ultrasonic vibrator intensively irradiates the ultrasonic vibration to the flow pipe part 120 only. To this end, the CNT solution 10 is formed to be narrow and long in the flowing direction (up and down direction based on FIG. 1 ).
접촉부(230)가 용액수용몸체부(110)의 외벽에 접촉되는 폭(W)은 유동관부(120)의 내경(D)보다 작거나, 유동관부(120)의 내경(D)의 2배 이하로 형성된다. The width W at which the contact portion 230 is in contact with the outer wall of the solution receiving body 110 is smaller than the inner diameter D of the flow tube portion 120, or twice the inner diameter D of the flow tube portion 120 or less is formed with
초음파 진동자부(200)는 유동관부(120)를 흐르는 CNT 용액(10)에 초음파를 가하여, 유동관부(120)를 흐르는 전체 CNT 용액(10) 안의 CNT는 모두 고른 초음파 힘을 받게 되므로, 기존의 초음파 분산 방법인 용기 내에 초음파 프로브를 이용하여 초음파를 조사하여 프로브 주위의 용액에 대해서 분산을 실시하는 방법과 달리, 유동관부(120)을 통과하는 유체의 전체 부피에 통하여 초음파를 고르게 조사할 수 있으므로, 단순히 초음파 프로브 하나를 사용하는 기존 초음파 분산기보다 뛰어난 초음파 분산 효과를 얻을 수 있다.The ultrasonic vibrator 200 applies ultrasonic waves to the CNT solution 10 flowing through the flow pipe unit 120, so that all CNTs in the CNT solution 10 flowing through the flow pipe unit 120 receive an even ultrasonic force. Unlike the method of dispersing the solution around the probe by irradiating ultrasonic waves using an ultrasonic probe in the container, which is an ultrasonic dispersion method, since ultrasonic waves can be evenly irradiated through the entire volume of the fluid passing through the flow pipe unit 120 . , it is possible to obtain a superior ultrasonic dispersion effect than a conventional ultrasonic disperser that simply uses one ultrasonic probe.
본 발명에 따른 탄소나노튜브 분산 장치(1)는 원추형 분산부(300)를 더 포함한다. 원추형 분산부(300)는 유동관부(120)의 출구부(123)의 내측에 장착된다. CNT 용액(10)은 원추형 분산부(300)와 충돌하게 되면서 출구부(123)의 외부로 배출된다. The carbon nanotube dispersing device 1 according to the present invention further includes a conical dispersing unit 300 . The conical dispersion part 300 is mounted inside the outlet part 123 of the flow pipe part 120 . The CNT solution 10 is discharged to the outside of the outlet portion 123 as it collides with the conical dispersion portion 300 .
원추형 분산부(300)는 원추형 분산몸체부(310)와 첨단부(320)를 포함한다. 원추형 분산몸체부(310)는 원추형으로 형성되는 것으로, 출구부(123)에 장착되어 출구부(123)의 하측(도 5 기준)으로 하향 경사진 경사면을 구비한다. 원추형 분산몸체부(310)는 용액수용몸체부(110)에서 연장 형성되는 지지대(미도시) 등에 의해 고정된다.The conical dispersion part 300 includes a conical dispersion body part 310 and a tip part 320 . The conical dispersion body part 310 is formed in a conical shape, and is mounted on the outlet part 123 and has an inclined surface inclined downward to the lower side (based on FIG. 5 ) of the outlet part 123 . The conical dispersion body part 310 is fixed by a support (not shown) that is formed extending from the solution receiving body part 110 .
첨단부(320)는 원추형 분산몸체부(310)의 단부(도 1 기준 상단부)에 뾰족하게 형성된다. 첨단부(320)는 출구부(123)를 통해 배출되기 전의 CNT 용액(10)에 충돌하여 CNT 용액(10)의 덩어리부(15)를 풀게 한다.The tip 320 is sharply formed at the end (the upper end of FIG. 1 ) of the conical dispersion body 310 . The tip 320 collides with the CNT solution 10 before being discharged through the outlet 123 to loosen the lump 15 of the CNT solution 10 .
유동관부(120)를 따라 내려오는 CNT 용액(10)은 초음파 진동자부(200)의 초음파 진동과, 나선가이드부(130)에 의한 교번 비틀림 힘에 의해 평행으로 덩어리부(15)로 붙어 있던 CNT 가닥이 풀어지나, 일부 풀어지지 않은 덩어리부(15)는 직관부(120a)를 통해 내려오면서 첨단부(320)와의 충돌되고 강한 유속에 의하여 덩어리부(15) 자체가 당겨져서 풀어지거나 CNT 가닥이 끊어지면서 풀러지게 된다. The CNT solution 10 coming down along the flow pipe part 120 is CNT attached to the lump part 15 in parallel by the ultrasonic vibration of the ultrasonic vibrator part 200 and the alternating torsion force by the spiral guide part 130 . The strands are released, but the lumps 15 that are not partially released come down through the straight pipe part 120a and collide with the tip 320, and the lumps 15 themselves are pulled and released by the strong flow rate or the CNT strands are released. When it breaks, it comes loose.
또한 첨단부(320)의 뾰족한 끝이 CNT 용액(10)이 경로 안 쪽에 있기 때문에, CNT 용액(10)이 출구(123)를 나오기 전에 첨단부(320)에서 압력이 높아지고 유속이 빨라진 상태로 출구부(123)를 빠져 나가게 되는데, 이 때 유체의 압력과 유속이 급격하게 줄어들게 되어서 CNT 덩어리부(15)가 서로 흩어지므로 분산 효과를 얻을 수 있다.In addition, since the sharp end of the tip 320 is inside the path of the CNT solution 10, the pressure at the tip 320 is high and the flow rate is increased before the CNT solution 10 exits the outlet 123. It exits the part 123, at this time, the pressure and flow rate of the fluid are rapidly reduced, so that the CNT lumps 15 are dispersed from each other, so that a dispersion effect can be obtained.
덩어리부(15)가 풀어진 CNT 용액(10)은 원추형 분산몸체부(310)의 경사면을 따라 내려가게 된다. The CNT solution 10 in which the lump 15 is released goes down along the inclined surface of the conical dispersion body 310 .
