工程を要する。Structures such as the two gymnasiums and heated swimming pools are always coated with zinc plating, which has excellent corrosion resistance. The J# high tension construction method is adopted for the steel frames and steel pipes of these structures. This construction method involves making the parts of the structure that are to be connected unplated in advance, and then overlapping the surfaces of these unplated parts. This is a method of tightening bolts, etc. to increase the friction coefficient due to rusting, thereby strengthening the bond between the two. Masking 1 to obtain this non-plated area has traditionally been a two-component type of epoxy paint. To be used, mix the il + 2 liquids and dilute with bath salt; (
2) Paint this 3-4 times; (3) 3-16 coats per coat
+ 141 hours of curing treatment Because the paint forms a solid layer on the adherend such as an iron vibrator by passing through the galvanizing bath, a complicated process such as scraping off the solid layer paint with a grinder is required.

ヤーブラシなどで簡単県こ取り除かれる。The tape or sheet 1 is not damaged in any way by either the acid treatment S or the flux treatment. In the next plating step, the surface film layer 2 melts and floats on the surface of the zinc yukata. When the sheet-like base material 3 is an organic fiber such as cotton cloth, the sheet-like base material 3 is carbonized with the adhesive layer 4. Since this carbonized layer remains layered in the predetermined mask area, it exhibits the desired masking effect. This part is not plated with zinc. When the sheet-like base material 3 is an inorganic fiber such as a glass nonwoven fabric, the sheet-like base material is supported by the carbonized vlJr of the adhesive layer 4 without being carbonized. In this case as well, the carbide of the adhesive layer 4 forms a layer on the portion to be masked and exhibits the desired masking effect. In the finishing process after plating, this carbide is easily removed using a wire brush or the like.

Next, it was dried at 110° C. for 10 minutes to obtain a cotton cloth-based double-sided pressure-sensitive adhesive sheet with a thickness of 0.2 mm. The above-mentioned 0.05 m low-density polyethylene film was laminated on one side of this double-sided pressure-sensitive adhesive sheet to obtain a bath-dip galvanized masking tape. This tape has a thickness of 4 fields [with a width of 50 m and a length of 4

The surface film, low-density polyethylene film, decomposes in the bath and floats on the surface of the zinc yukata. In the finishing process after plating, this carbonized layer was simply removed with a feather.

Use 30% bath solution of PS-43001 diluted to 20% with doluol. Five glass nonwoven fabrics were immersed in this, and then dried at 120°C for 10 minutes to obtain a glass nonwoven fabric base double-sided sticky layer sheet with a thickness of 0.2 mm.

きた。One side of this double-sided adhesive sheet was laminated with the above tetrafluoroethylene copolymer film to form a masking tape. This tape, J4UL in thickness, was wrapped once around the area to be masked of an iron plate with a width of 50 mm and a length of 400 mm, so as to fit in the gap 4. This was subjected to bath-dip galvanizing in the step shown in the light above.
However, even if the processing temperature and processing time are the most severe conditions, there is no damage to the tetrafluoroethylene copolymer film. Unacceptable force 1 - 0 Next, in the plating process, the adhesive layer is carbonized and this carbonized layer should be used as a predetermined mask.
The entire surface was covered with an amount of 1b, which was supported by the glass nonwoven fabric, and the desired masking effect was achieved. In the finishing process after plating, the carbonized layer was easily removed by lightly rubbing the glass nonwoven fabric with a wire brush.

Add 25g of isocyanate curing agent (trade name: Corofuitol, manufactured by Nippon Polyurethane Co., Ltd.) to the base ratio.
One is equipped. One glass woven fabric layered sheet on one side was obtained.
The strained tetrafluoroethylene copolymer film was laminated with a pressure roll at 100°C in the same manner as in Example 2. After the resulting laminated product was left for 24 hours, synthetic rubber was applied to the exposed surface of the nonwoven fabric. Adhesive′? r: 1 coat applied. All other operations were the same as in Example 2 to obtain a masking tape. As with Example 2, excellent masking effects were also confirmed for this tape.

精度を保持することができる０By using the masking tape or sheet of the present invention, not only can all the steps required for conventional paint-type masking be omitted, but it is also excellent in terms of safety and health as it is free of toxicity caused by organic solvents and hardening agent IC. It is possible to perform production under the environment. Furthermore, since no masking material that would stick to the layer is used in the plating process, the masking part can be easily exposed in the finishing process after plating, which greatly reduces the number of man-hours and prevents damage. 0 that can maintain the accuracy of the attachment
