GAS LEAKAGE PART REPAIRING METHOD

Japanese Patent JP2017089878

A

PROBLEM TO BE SOLVED: To enable a gas leakage part to be repaired in a short time.SOLUTION: An elastic transparent mat body 2 is mounted at a pressing surface part of light transmittable pressing tool 3, a transparent resin film 1 is applied to cover a surface part of the transparent mat body 2, a pressing surface opposite to a contact surface with the transparent mat body 2 at the transparent resin film 1 is coated with light hardening resin composition 4 mixed with [A] 30 to 40 mass part of bisphenol type A epoxy acrylate, [B] 1.0 to 2.0 mass part of titanocene-based initiator, and [C] 37 to 48 mass part of filler to form non-hardened resin layer adhesion part in advance, the non-hardened resin layer adhesion part is pushed against a gas leakage location 6 at piping facility to form a covering part, light is radiated against the covering part while the transparent resin film 1 is pushed from outside against the gas leakage location 6 against gas pressure through the transparent mat body 2 and the pressing tool 3 to keep air-tightness, light hardening resin composition 4 is reacted in hardening to form a seal part.SELECTED DRAWING: Figure 1
