습강 무진지의 제조방법{wet strength clean paper manufacture method}Wet strength clean paper manufacture method

본 발명은 무진지를 제조하기 위한 방법에 관한 것으로, 좀 더 상세하게는 원지를 함침하기 위해 습윤지력증강제를 포함하는 1차 및 2차 함침부를 형성시키되, 상기 1차 함침부는 가압롤러와 함침롤러를 각각 형성하여 하단의 제1함침롤러에 묻은 함침액이 제2함침롤러에 전이되어 원지의 일면이 함침되며, 상기 원지는 제1건조기로 이송되어 1차 건조된 후, 2차 함침부에서 원지의 이면이 함침되어 제2건조기를 통과하고, 가이드롤러를 거쳐 다시 감기게 되는 것으로 구성되어, 무진지의 제작시에 원지가 지절되는 것을 방지할 수 있으며, 기존의 재생 무진지 제조 설비를 이용함으로써 재생 무진지와 습강 무진지를 같이 생산할 수 있는 효과가 있는 습강 무진지의 제조 방법에 관한 것이다.The present invention relates to a method for manufacturing dust-free paper, and more particularly, to form a primary and secondary impregnation comprising a wet strength enhancer to impregnate the base paper, the primary impregnation is a pressure roller and an impregnation roller Each impregnation liquid formed on the first impregnation roller at the bottom is transferred to the second impregnation roller to impregnate one side of the base paper, and the base paper is transferred to the first dryer and dried first, and then the secondary paper impregnation The back surface is impregnated and passed through the second dryer, and then rewound through the guide roller, which can prevent the paper from being crushed during the production of dust-free paper. It relates to a method for producing wet steel dust-free paper that can produce both dust-free and wet steel dust-free paper together.

일반적으로 무진지는 종이의 미립자 발생 및 이온성분, 정전기가 최소화 되도록 제어한 특수지로서 반도체 및 첨단전자, 생산공장의 크린룸(clean room)내에서 사용되는 특수 가공지이며, 이러한 무진지는 폴리올레핀계 또는 폴리스티렌계 수지를 이용하여 제조한 합성지가 주로 사용되었으나, 이들은 내열성 부족으로 인한 복사성 불량과 정전기 발생 그리고 발진량의 과다 등의 문제점이 지적되었다.In general, dust-free paper is a special paper that is controlled to minimize the generation of fine particles, ionic components and static electricity of paper, and is a special processed paper used in clean rooms of semiconductors, high-tech electronics, and production plants. Such dust-free paper is polyolefin-based or polystyrene-based. Synthetic paper made of resin was mainly used, but these problems were pointed out such as poor radiation property, generation of static electricity and excessive amount of dust due to lack of heat resistance.

이에, 작금에는 셀롤로오스를 주체로 한 원지에 고분자수지를 함침 또는 도포시킨 함침형 무진지로 대체되어 가고 있다. 상기 무진지는 셀롤로오스를 주체로 하기 때문에 내열성이 우수하고, 지중 중에 함유된 고분자 수지가 지층을 구성하는 섬유의 미세 섬유간의 결합을 강하게 하여 먼지나 미세입자의 발생을 감소시켜 발진성을 매우 낮출 수 있다. Thus, in recent years, it has been replaced by an impregnated dust-free paper in which a polymer resin is impregnated or coated on a base paper mainly composed of cellulose. Since the dust-free paper is mainly composed of cellulose, the heat resistance is excellent, and the polymer resin contained in the ground strengthens the bonds between the fine fibers of the fibers constituting the ground layer, thereby reducing the generation of dust and fine particles, thereby lowering the oscillation property. Can be.

종래의 무진지 제조방법은 도 1에 도시한 바와 같이 원지를 액팬에 완전히 적셔 표면과 이면에 함침한 후, 스퀴즈롤에서 압력을 가해 도공량과 수분을 조절하는 방법이나, 또는 1함침부와 2함침부를 각각 형성하고 전이롤러에 의해 함침액을 전이시켜 코팅하는 재활용 무진지 제조 방법이 있다.
