Description

내마모성 복합표면처리 롤러{ROLLER COATING TREATMENT CHROMIUM AND POLY TETRAFLUORO}Abrasion Resistant Composite Surface Treatment Roller {ROLLER COATING TREATMENT CHROMIUM AND POLY TETRAFLUORO}

본 발명은 내마모성 복합표면처리 롤러에 관한 것으로, 보다 상세히는 롤러의 이형성이 높고 마찰계수가 낮아 롤러의 유지보수 및 롤러에 의한 처리재의 작업이 원활히 이루어짐은 물론 내마모성이 우수하여 롤러의 사용 수명을 연장할 수 있도록 구성된 내마모성 복합표면처리 롤러에 관한 것이다.The present invention relates to a wear-resistant composite surface treatment roller, and more particularly, high roller releasability and low coefficient of friction to facilitate the maintenance of the roller and the processing of the processing material by the roller, as well as excellent wear resistance to extend the service life of the roller. A wear resistant composite surface treatment roller configured to be capable of

일반적으로 베이스필름이나 제지기 등에 사용되는 롤러는 사용분위기 및 용도에 따라 내구성, 승온 안정성 등이 요구되고 있다.In general, rollers used in base films, paper machines, and the like are required to have durability, temperature stability, and the like depending on the use atmosphere and purpose.

국내에서 사용되는 대부분의 롤러(10)는 도 1a에 도시한 바와 같이 봉 형상인 소지금속샤프트(11)의 표면에 내식성 내마모성이 우수한 경질크롬(12)을 표면에 도금한 크롬도금 롤러(10)가 널리 사용되고 있다.Most rollers 10 used in Korea are chromium plated rollers 10 having plated hard chromium 12 having excellent corrosion resistance and abrasion resistance on the surface of rod-shaped base metal shaft 11 as shown in FIG. 1A. Is widely used.

그러나, 상기 크롬도금 롤러(10)는 내식성 내마모성이 높아 오래 사용할 수 있는 반면 사용 중 이 물질에 의한 표면 오염이 쉽고 베이스필름을 제조하는 경우에는 롤러(10)와 처리재 사이의 이형성이 낮아 크롬도금 롤러(10)에서 처리재가 잘 떨어지지 않기 때문에 처리재가 파손될 수 있는 단점이 있었다.However, the chromium plating roller 10 has a high corrosion resistance and abrasion resistance, and thus can be used for a long time, whereas surface contamination by this material during use is easy, and in the case of manufacturing the base film, the releasing property between the roller 10 and the treating material is low. Since the treatment material does not fall off from the roller 10, the treatment material may be damaged.

또한, 상기 와 같은 단점을 보완하기 위하여 봉 형상인 소지금속샤프트(11)의 표면에 테프론과 같은 불소계수지(13)를 코팅 처리한 불소수지 롤러(10)가 널리 이용되고 있다.In addition, the fluorine resin roller 10 is coated with a fluorine resin 13, such as Teflon on the surface of the rod-shaped base metal shaft 11 in order to compensate for the above disadvantages are widely used.

이러한 불소수지 롤러(10)는 비점착성이 우수하며 이형성이 높고 마찰계수가 낮으며 내화학성이 우수한 장점을 지니고 있어 공업용 표면처리 분야에서 널리 이용되고 있다.The fluororesin roller 10 is excellent in non-tackiness, has high releasability, low coefficient of friction, and excellent chemical resistance, and thus has been widely used in industrial surface treatment.

그러나, 최근에는 생산성의 향상을 위하여 베이스필름과 같은 피 처리재의 폭이 넓어지고 생산속도가 빨라지는 등 불소수지 롤러(10)의 사용조건이 보다 가혹해짐과 아울러 불소계수지(13)의 물성이 약하기 때문에 상기 처리재의 장력이 집중되는 불소수지 롤러(10)의 양측 부분이 오랜기간 지나지 않아 쉽게 마모되어 불소수지 롤러(10)에 의해 이송되는 처리재가 일측으로 편심되는 문제점이 있음은 물론 이를 자주 수정하거나 마모된 불소수지 롤러(10)를 교체하다 보면 도리어 생산의 효율성이 떨어지는 단점이 있었다.However, in recent years, in order to improve the productivity, the conditions for use of the fluorine resin roller 10 become more severe and the physical properties of the fluorine resin 13 are weaker, such as the width of the material to be treated such as the base film and the production speed are increased. Therefore, both sides of the fluorine resin roller 10 in which the tension of the treatment material is concentrated are easily worn after a long period of time, so that the treatment material conveyed by the fluorine resin roller 10 is eccentrically to one side, of course, often modified or Replacing the worn fluorine resin roller 10 had a disadvantage in that the efficiency of production rather than falling.

이에 내마모성이 높으면서도 비점착성이 우수하며 이형성이 높고 마찰계수가 낮으며 내화학성이 우수한 롤러(10)의 필요성이 요구되었다.Accordingly, a need for a roller 10 having high wear resistance and excellent non-tackiness, high releasability, low coefficient of friction, and excellent chemical resistance was required.

본 발명은 상기한 바와 같은 요구에 의해 안출된 것으로, 그 목적은 종래에 경질크롬 롤러와 같은 우수한 내식성 및 내마모성 그리고 종래에 불소수지 롤러와 같은 우수한 이형성 및 비점착성을 동시에 겸비하여 롤러의 수명연장과 유지보수 및 롤러에 의한 처리재의 작업이 원활히 이루어질 수 있도록 구성된 내마모성 복합표면처리 롤러를 제공하고자 하는 것이다.The present invention has been made in accordance with the above-mentioned demands, and its object is to combine the excellent corrosion resistance and abrasion resistance, such as a hard chromium roller, and the excellent releasability and non-adhesiveness, such as a fluororesin roller. It is an object of the present invention to provide a wear-resistant composite surface treatment roller configured to facilitate maintenance and operation of the treatment material by the roller.
