[0027] The present invention will be described in detail below with reference to specific examples and drawings.
[0028] A method for repairing thermal insulation structure: processing the damaged part of the thermal insulation structure, and processing the irregular damaged part into a regular-shaped repair hole, and the processing method is low-speed processing, and the radial size of the repair hole is larger than the damaged part The radial size of the repair block is larger than 5mm; the repair block with similar shape to the repair hole is processed, and n glue grooves are set in the longitudinal direction of the repair block; the side and bottom surface of the repair block, and each surface of the repair hole are evenly coated with high-temperature adhesive Place the repair block in the repair hole to ensure that the high temperature resistant adhesive can fill the gap between the repair block and the repair hole; after curing the high temperature resistant adhesive, polis...
