본 발명은 산업용 다공성 수지필터 박막 소결방법에 관한 것으로, 더욱 상세하게는 HDPE(고밀도 폴리에틸렌)소립분말을 박막형태로 금형에 충전한 후 전자파 조사를 통한 분자운동으로 소결하는 방법으로 기존에 제작이 불가능 했던 박막형의 다공성 수지 필터를 소결하는 방법에 관한 것이다.The present invention relates to a method for sintering a thin film of an industrial porous resin filter, and more specifically, it is impossible to manufacture a conventional method by sintering by HDPE (high density polyethylene) particle powder in a thin film form and then sintering by molecular motion through electromagnetic wave irradiation. It relates to a method of sintering a thin-film porous resin filter.

일반적으로 다공성 수지 필터의 제작은 도 1의 경우와 같이 고밀도 폴리에틸렌(이하 "HDPE"라 통칭함) 분말을 알루미늄 금형에 충전 후 전기열풍로에서 가열하여 소결하는 방식이다. 그러나 이러한 소결방식은 두께 0.25mm 이하의 박막형 필터를 제작하는 대 있어서 HDPE분말의 균일한 충전이 불가능 할 뿐만 아니라, 전기열풍로를 이용하여 외부에서 가열하는 방식이므로 수지소재의 비교적 낮은 열전도성 때문에 통상 1?2시간에 달하는 긴 소결시간이 필요하게 되며, 박막형 필터 소결 시 균일한 소결상태를 기대하기 어려운 문제점이 발생된다.In general, a porous resin filter is manufactured by filling a high-density polyethylene (hereinafter referred to as "HDPE") powder in an aluminum mold and heating it in an electric hot stove as in the case of FIG. However, this sintering method is not only possible to uniformly fill the HDPE powder in the production of thin film filters having a thickness of 0.25 mm or less, but also because of the method of heating externally by using an electric hot stove, because of the relatively low thermal conductivity of the resin material. A long sintering time of 1 to 2 hours is required, and it is difficult to expect a uniform sintering state when sintering a thin film filter.

본 발명은 기존의 산업용 다공성 수지 필터 보다 얇은 박막형의 다공성 수지 필터 생산에 있어서, HDPE 분말을 박막형태로 금형에 고르게 충전함은 물론, 정밀한 규격의 산업용 다공성 수지필터를 효율적으로 제작하는 방법을 제공하는데 그 목적이 있다.The present invention, in the production of a thin-film porous resin filter thinner than the conventional industrial porous resin filter, HDPE powder evenly filled in the mold in a thin film form, as well as providing a method for efficiently manufacturing an industrial porous resin filter of precise specifications. The purpose is.

본 발명은 산업용 다공성 수지필터를 박막형태로 제작하는데 있어서, 박막형태로 HDPE 분말을 충전하기 위해 금형 표면에 접착물질을 도포하는 단계, 금형에 HDPE 분말을 충전하고 이를 적층하는 단계, 적층된 금형을 수분동안 전자파 조사를 통해 내열(內熱)소결 단계, 상기 단계 후 금형을 공랭(空冷)하여 제작된 박막형 다공성 수지 필터를 플레이트 및 디스크로 성형하여 탈락하는 단계로 이루어진 것에 특징이 있다.The present invention is to produce an industrial porous resin filter in the form of a thin film, the step of applying an adhesive material on the surface of the mold to fill the HDPE powder in the form of a thin film, the step of filling the HDPE powder in the mold and laminating it, the laminated mold Heat-sintering step through the electromagnetic wave for a few minutes, characterized in that consisting of the step of forming a thin film-type porous resin filter produced by air cooling the mold after the step to form a plate and a disk dropping.

본 발명은 접착물질을 이용하여 박막형태의 HDPE 분말 충전이 가능함은 물론, 전자파 조사를 통해 HDPE 분말의 내열(內熱)발생을 유도하여 짧은 시간으로 균일한 소결상태를 얻을 수 있음은 물론, 기존에 불가능 했던 두께 0.25mm 이하 박막형 산업용 다공성 수지필터를 저탄소 환경 친화적인 방법으로 대량 제작이 가능하게 되었다.The present invention can be filled with HDPE powder in the form of a thin film using an adhesive material, as well as inducing heat generation of the HDPE powder through electromagnetic radiation to obtain a uniform sintered state in a short time. It was possible to mass-produce thin-walled industrial porous resin filters with a thickness of less than 0.25mm, which was impossible because of low carbon environmentally friendly methods.

본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention will now be described in detail with reference to the accompanying drawings.

도 2는 박막형 수지 필터를 소결하기 위한 강화유리금형과 이에 도포된 접착 제 그리고 HDPE분말의 도포형태를 나타낸 구조도로서, 강화유리로 제작된 금형에 박막형태로 HDPE분말을 충전하는 과정을 살펴보면 다음과 같다. 도 2-a와 같이 평면 형태의 강화유리(1)에 접착제(2)를 도포한다. 그 후에 도 2-b와 같이 도포된 접착제(2)를 이용하여 HDPE분말(3)을 고르게 충전한다. 이때 접착제(2)가 도포된 부분에만 HDPE분말(3)의 충전이 이루 어 진다.Figure 2 is a structural diagram showing the application form of the tempered glass mold, the adhesive applied to it and the HDPE powder for sintering the thin film resin filter, the process of filling the HDPE powder in the form of a thin film in a mold made of tempered glass as follows. same. The adhesive 2 is applied to the tempered glass 1 of the planar shape as shown in FIG. Thereafter, the HDPE powder 3 is evenly filled using the adhesive 2 applied as shown in FIG. At this time, the filling of the HDPE powder 3 is made only in the portion where the adhesive 2 is applied.

그 다음 도 3은 최종적으로 완성한 금형형태를 나타낸 구조도이다. 도 2의 방법으로 HDPE분말(3)의 충전이 완료된 강화유리(1) 사이에 제작하고자 하는 필터의 두께에 대응하는 휠라게이지(4)를 삽입 후 적층하여 금형을 완성한다.3 is a structural diagram showing the final mold shape. The method of FIG. 2 inserts the wheel gauge 4 corresponding to the thickness of the filter to be produced between the tempered glass 1 of which the HDPE powder 3 is filled, and laminates the mold.

다음으로 도 4는 도 3에서 완성된 금형을 전자파조사장치(5)를 이용하여 전자파를 조사하는 과정과 완성된 필터를 성형하는 형태를 나타낸 것이다. 고출력의 전자파를 수 분간 조사하면 HDPE분자의 운동에 의해 내열(內熱) 발생하게 되며, 각 HDPE분말의 접합면이 용융하여 소결되게 된다. 전자파 조사 과정이 끝난 다음 금형을 공랭(空冷)하고 플레이트 및 디스크로 성형하여 탈락하면 박막형태의 다공성 수지 필터가 완성된다.Next, FIG. 4 illustrates a process of irradiating electromagnetic waves using the electromagnetic wave irradiation apparatus 5 and molding the completed filter in FIG. 3. When irradiated with high power electromagnetic waves for several minutes, heat is generated by the motion of HDPE molecules, and the bonding surface of each HDPE powder is melted and sintered. After the electromagnetic wave irradiation process, the mold is air-cooled, molded into a plate and a disk, and dropped out to form a thin-film porous resin filter.

이를 전체적인 과정의 흐름으로 보면 도 5의 경우와 같으며, 도 1에서 볼 수 있는 기존의 알루미늄 금형을 이용한 전기열풍식 소결 방법에 비하여 훨씬 얇고 정밀한 다공성 수지필터의 제작이 가능하며, 짧은 제작시간과 적은 전기에너지 소모로 높은 생산효율 달성 할 수 있다This is the same as the flow of the overall process as in the case of Figure 5, it is possible to manufacture a much thinner and more precise porous resin filter than the electro-hot air sintering method using the conventional aluminum mold shown in Figure 1, short production time and High production efficiency can be achieved with less electric energy consumption
