Description

산업용 패킹의 제조방법{Manufacturing method of Industrial packing}Manufacturing method of Industrial packing

본 발명은 산업용 패킹의 제조방법에 관한 것으로, 더욱 상세하게는 산업용 패킹 중 석면사, 탄화섬유, 테프론(P.T.F.E.)섬유, 유리섬유, 그라파이트섬유, G.F.O.섬유(P.T.F.E.에 흑연을 분산시켜 만든 첨단의 섬유를 말함), 인코넬(Inconel), 서스와이어(Sus wire)들 중 어느 하나를 선택하여 테프론과 윤활유를 함침시킴으로써, 상기 산업용 패킹을 통해 패킹의 장력을 증대시키고, 산업용 패킹내에 테프론의 흡수율을 증대시켜 내열성, 밀폐성, 내약품성을 증대시킬 수 있는 산업용 패킹에 관한 것이다.The present invention relates to a manufacturing method of industrial packing, and more particularly, asbestos, carbonized fiber, Teflon (PTFE) fiber, glass fiber, graphite fiber, GFO fiber (high-tech fiber made by dispersing graphite in PTFE) By impregnating Teflon and lubricant by selecting any one of Inconel and Sus wire, thereby increasing the tension of the packing through the industrial packing and increasing the absorption rate of Teflon in the industrial packing. The present invention relates to an industrial packing that can increase sealing, chemical resistance, and the like.

또한, 고속회전체에서의 고온 및 고압이 발생되는 부품소재에서 밀봉의 소재로 사용되는 패킹에서 고속회전에서 발생되는 고온 및 고압에 견디는 패킹을 제조하는 데 있다.In addition, the present invention provides a packing that can withstand high temperature and high pressure generated at high speed in a packing used as a sealing material in a component material where high temperature and high pressure are generated at a high speed rotating body.

일반적으로 산업용 패킹은 장력이 우수한 탄화섬유 또는 유리섬유사를 연사하여 직조한 후 테프론에 함침시키거나, 흡수율이 우수한 아크릴사를 연사하여 직조한 후 테프론에 함침시켜 제조하여 고내압성, 내약품성을 요하는 패킹용으로 사용되거나, 내열성 윤활유를 유입하여 윤활성 및 유연성을 요하는 유기용제를 밀폐하기 위해 사용되는 것이다.In general, industrial packing is manufactured by weaving by weaving carbon fiber or glass fiber with excellent tension and impregnating it with Teflon, or by weaving by weaving acrylic yarn with good water absorption and then impregnating with Teflon to require high pressure resistance and chemical resistance. It is used for packing or to seal the organic solvent that requires lubricity and flexibility by introducing heat-resistant lubricant.

하지만 탄화섬유, 석면 및 유리섬유만으로 패킹을 형성하게 되면, 작업공정 중 유리섬유가 비산되어 인체에 매우 유해한 영향을 미칠 뿐만 아니라, 상기섬유들의 테프론 흡수율이 낮아 작업시간이 매우 길어지는 동시에 테프론이 침투되지 못한 부분으로 유기용제가 유출되는 등의 문제가 발생된다.However, if the packing is formed only of carbonized fiber, asbestos and glass fiber, the glass fiber is scattered during the working process, which not only has a very detrimental effect on the human body, but also the Teflon absorption rate of the fibers is very low, resulting in very long working time and penetration of Teflon. Problems such as the outflowing of organic solvents to the parts that do not occur.

또한, 고온 및 고압이 발생되는 점에서 기존의 패킹에 있어서는 표면의 마찰로 인해 패킹의 부식 및 클랙(Crack)이 발생으로 인한 패킹의 피로현상으로 인해 패킹의 잦은 교체가 이루어져야 하며, 작업장에서의 사고의 위험이 발생될 우려가 있다.In addition, in the case of high temperature and high pressure, the existing packing has to be replaced frequently due to the fatigue of the packing due to the corrosion of the packing and the cracking of the packing due to the friction of the surface. There is a risk of the risk of occurrence.
