The present invention (Examples 4-1 to 4-6) specifies the catalyst sheet forming step. A number of pores are formed inside the support, and the catalyst solvent is placed in the pores and then dried to form a catalyst layer. In addition, in order to increase the efficiency of the subsequent drying step and ensure a homogeneous thickness of the medium layer, the removal step of the remaining catalyst solvent is implemented continuously. In the impregnation step, the support is introduced and discharged into the impregnation container containing the catalyst material, and while the support passes through the impregnation container, the impregnation material is accommodated in the pores of the support.

A pair of compression rollers located inside the impregnation container compresses and transports the support. During the process of compression by the compression roller, air contained in the pores is discharged to the outside, and during the process of being discharged by the compression roller, the catalyst material penetrates into the pores. In other words, the effect of the catalyst material being easily accommodated inside the plurality of pores can be obtained through the process of the pressing roller. These pressing rollers are formed in large numbers and the process is carried out in multiple stages.

There may be excessively attached catalyst material on the surface of the support due to surface tension. To remove this, a scraper is mounted on the outside of the impregnation vessel. The scraper contacts both sides of the support, and can remove catalyst solvent excessively attached to the surface during the movement of the support. In order to increase the impregnation effect of the catalyst material, a stirrer 850 is installed inside the impregnation vessel to form circulation of the catalyst material, and the temperature of the catalyst material can be kept constant through the temperature control device 860. In addition, impregnation can be performed by oscillating ultrasonic waves using the ultrasonic oscillator 841 mounted inside the impregnation container.

[Example 5-7] The present invention relates to a method for manufacturing a bipolar ion exchange membrane. In Example 4-1, the comma coater, scraper, or sprayer is operated by an actuator 740, and the coating layer thickness is indirectly measured. It is measured by a device, and the thickness controller 750 includes operating the comma coater, scraper, and sprayer in real time by signals from the indirect measurement device 760.
본 발명(실시예 5-1 내지 5-7)은 촉매층 양단에 극이 상이한 이온교환층 형성을 구체화 한다. 즉 촉매층 일측에는 양이온교환막을 형성하며, 타측에는 음이온교환막을 형성한다. 상기 양이온교환막 및 음이온교환막은 동시에 형성됨을 특징으로 한다. 또한, 양이온교환막 및 음이온교환막의 두께를 상이하게 형성하는 특징을 가진다. The present invention (Examples 5-1 to 5-7) embodies the formation of ion exchange layers with different polarities at both ends of the catalyst layer. That is, a cation exchange membrane is formed on one side of the catalyst layer, and an anion exchange membrane is formed on the other side. The cation exchange membrane and the anion exchange membrane are characterized in that they are formed simultaneously. In addition, it has the feature of forming different thicknesses of the cation exchange membrane and the anion exchange membrane.
설정된 두께로 각각의 이온교환막을 형성하므로 두께를 측정하는 단계 및 두께를 제어하는 단계를 동시에 구현해야 된다. 상기 두께설정에 있어서, 콤마코터방식, 캐스팅방식, 분무방식이 사용되며, 캐스팅블레이드의 두께변화, 콤마코터의 축거리 변화, 분무량 변화를 가변적으로 형성하며, 이들은 엑츄에이터에 의해 작동됨을 특징으로 한다. 가변하는 이유는 설정된 두께로 이온교환층을 형성하기 위함이다. 또한 완전하게 이온교환층이 형성되려면, 지지체(촉매층)이 일정한 장력을 유지하여 평평도를 구현해야 된다. 따라서 후술되는 장력유지단계가 동시에 제어됨을 특징으로 한다. Since each ion exchange membrane is formed with a set thickness, the steps of measuring the thickness and the steps of controlling the thickness must be implemented simultaneously. In setting the thickness, the comma coater method, casting method, and spray method are used, and the thickness change of the casting blade, the axis distance change of the comma coater, and the spray amount change are variably formed, and these are characterized in that they are operated by an actuator. The reason for the change is to form an ion exchange layer with a set thickness. Additionally, in order for the ion exchange layer to be completely formed, the support (catalyst layer) must maintain a constant tension to achieve flatness. Therefore, the tension maintenance step described later is characterized by being controlled simultaneously.
음이온교환층 두께가 양이온교환층 두께보다 두껍게 형성됨이 바람직하다. 이는 각각의 이온교환?v 함수율을 동일하게 유지하고자 함이다. 최적의 물분해 효율을 놀치기 위해서는 동일한 함수율을 유지해야 되며, 동일한 함수율이 형성되면, 팽윤율이 동일하다. 이는 촉매층과 이온교환층의 변형을 방지하므로 층간분리를 방지하는 효과를 얻을 수 있다. It is preferable that the anion exchange layer is thicker than the cation exchange layer. This is to keep the moisture content of each ion exchange the same. In order to achieve optimal water decomposition efficiency, the same moisture content must be maintained, and when the same moisture content is formed, the swelling rate is the same. This prevents deformation of the catalyst layer and the ion exchange layer, thereby preventing interlayer separation.
[실시예 6-1] 본 발명은 본 발명은 바이폴라이온교환막 제조방법에 대한 것이며, 실시예 1-1에 있어서, 상기 코팅단계 중, 지지체의 장력을 일정하게 유지하는 장력유지단계(S500);를 포함하는 시계열적 절차로 이루어진다. [Example 6-1] The present invention relates to a method for manufacturing a bipolar ion exchange membrane. In Example 1-1, during the coating step, a tension maintenance step (S500) of maintaining the tension of the support constant; It consists of a time series procedure including.
본 발명(실시예 6-1)은 지지체의 장력을 일정하게 유지하는 목적을 가진다. 지지체의 양단면에 각각의 이온교환층을 동시에 형성하며, 각각의 이온교환층 두께는 상이하게 형성된다. 또한 수평으로 이동되는 지지체는 중력에 대한 영향을 받는다. 이러한 변형조건을 방지하기 위해서는 지지체는 일정한 평행도를 유지해야 한다. 일정한 평행도는 장력유지단계에 의해 제어됨을 특징으로 한다. 따라서, 장력유지단계는 장력측정단계(S510), 장력발생단계(S520)로 구분되며, 장력발생단계는 장력제어단계(S530)에 의해 작동됨을 특징으로 한다. 이를 구현하기 위해서는 기초가 되는 지지층이 일정하게 평행도를 유지해야 한다. 일정한 평행도를 유지하기 위해 장력이 적용되어야 한다. The purpose of the present invention (Example 6-1) is to keep the tension of the support constant. Each ion exchange layer is formed simultaneously on both end surfaces of the support, and the thickness of each ion exchange layer is formed differently. Additionally, supports that are moved horizontally are affected by gravity. In order to prevent such deformation conditions, the support must maintain a certain degree of parallelism. The constant parallelism is characterized by being controlled by a tension maintenance step. Therefore, the tension maintenance step is divided into a tension measurement step (S510) and a tension generation step (S520), and the tension generation step is characterized by being operated by a tension control step (S530). In order to implement this, the underlying support layer must maintain a constant degree of parallelism. Tension must be applied to maintain constant parallelism.
장력제어를 위해 장력측정센서(440)가 상기 지지체 일면 및/또는 타면에 하나 또는 복수로 형성되며, 상기 센서에 의해 검측된 결과는 장력제어기(430)에 의해 전송된다. 장력제어기에 전성된 데이터는 지지체를 이송시키는 구동롤러 및 종동롤러의 압착력 및 속도를 제어한다. For tension control, one or more tension measuring sensors 440 are formed on one side and/or the other side of the support, and the results detected by the sensors are transmitted by the tension controller 430. The data transmitted to the tension controller controls the compression force and speed of the driving roller and driven roller that transport the support.
