ている。BACKGROUND ART Conventionally, a method of cleaning this type of metal member has been a procedure as shown in FIG. A metal member that is in sliding contact with the magnetic tape and is ground using a water-soluble grinding fluid.
For example, tape guides made of stainless steel with chrome plating and further grinding are placed in a metal mesh basket 1 containing 100 to 1000 pieces, immersed in a washing tank 2, and then immersed in a kerosene tank 3. At this stage, macroscopic dirt and oils are removed.

洗浄される。 Next, the car 1 is immersed in an ultrasonic cleaning bath 4 using trichloroethane, a cooling bath 5 containing a cold solution of trichlorethane, and then a steam cleaning bath 6 that also uses trichlorethane as a cleaning agent.
The sample is suspended in trichloroethane vapor for steam cleaning.
超音波洗浄槽４、冷却槽５及び蒸気洗浄槽６は
通常は１台の洗浄機７として構成されていて、か
ご１は各槽中に0.5ないし３分間程度留まるよう
にして洗浄を行なつている。 The ultrasonic cleaning tank 4, the cooling tank 5, and the steam cleaning tank 6 are usually configured as one cleaning machine 7, and the basket 1 stays in each tank for about 0.5 to 3 minutes to perform cleaning. There is.

ルエタンと共沸してかご１の中のテープガイドに
付着して、テープガイドの表面に分子膜程度の厚
さの被覆を作る。Problems to be Solved by the Invention In such a conventional method, dirt such as moisture, kerosene, and water-soluble grinding fluid adhering to the tape guide and the car 1 is not completely cleaned at each stage and is transferred to the next tank one after another. In particular, the kerosene brought into the liquid 6a in the steam cleaning tank, which is the final process, azeotropes with trichloroethane and adheres to the tape guide in the cage 1, causing a droplet to form on the surface of the tape guide. Create a coating as thick as a molecular film.
液６ａ中には初めは灯油は含まれないが、微少

ープガイド等の表面で冷却されて液化する際にそ
の表面の灯油を溶解して槽６に滴下して、洗浄を
重ねるに従つて液６ａの中の灯油は増加するので
ある。 Initially, liquid 6a does not contain kerosene, but as a result of steam cleaning the tape guide and car 1 to which a small amount of kerosene has adhered, trichloroethane vapor cools on the surface of the tape guide and liquefies. The kerosene on the surface of the liquid 6a is dissolved and dripped into the tank 6, and as the cleaning is repeated, the amount of kerosene in the liquid 6a increases.
液６ａは新液との交換回数を増やすと非経済的
で、実用的でない。 It would be uneconomical and impractical to increase the number of replacements of the liquid 6a with new liquid.
このようにしてテープガイドの表面に灯油の薄
膜が残留していると、テープガイドに磁気テープ
が摺接するときの摩擦係数が高くなつて好ましく
ない。 If a thin film of kerosene remains on the surface of the tape guide in this manner, the coefficient of friction when the magnetic tape comes into sliding contact with the tape guide increases, which is undesirable.
また、灯油の持ち込みを避けるために灯油槽３
への浸漬を行わないと、多量の水分が超音波洗浄
槽４に持ち込まれて溶剤の劣化を極端に早めて好
ましくない。 In addition, to avoid bringing in kerosene, kerosene tank 3
If immersion is not carried out, a large amount of water will be carried into the ultrasonic cleaning tank 4, which is undesirable as it will extremely accelerate the deterioration of the solvent.
本発明はこのような問題点を解決するもので、
表面が高度に清浄な金属表面を得られる洗浄法を
提供するものである。 The present invention solves these problems,
The present invention provides a cleaning method that allows a highly clean metal surface to be obtained.

To explain using the same numbers as in the conventional example, a tape guide that has been ground using a water-soluble grinding liquid is placed in a basket 1. Washing tank 2, kerosene tank 3,
The tape guide 8 is immersed or cleaned in the order of the washing machine 7, and the tape guide 8 is rotated in the direction of arrow B while reciprocating the wiper 9 made of a cellulose-based binder-free nonwoven fabric that does not contain oil or fat in the direction of arrow A. It wipes away the.
