Industrial repair glue repair process common defects below to explain the solution for you:
1. Coating sticky: low temperature, not fully cured or not curing; preparation of the repair agent is not uniform; repair agent A, B component ratio improper, B component too little; curing time is not enough.
Solution: to improve the curing temperature; stirring evenly; strictly according to the ratio of weighing; to extend the curing time.
2. The coating is too brittle: too much curing agent; curing speed is too fast; curing temperature is too high, curing.
Solution: in strict accordance with the preparation; reduce the heating rate ladder heating; strictly control the curing temperature, so that below 100 ℃.
3. Coating pores: stirring speed too fast, mixed with air; viscosity is too large, wrapped in air; empty when not pressed hard.
Solution: slow down the mixing speed, stirring in the same direction; improve the construction environment temperature, reduce viscosity; repeatedly press the coating, discharge the air.
4. The coating is loose; the surface treatment is not clean; surface treatment after the parking time is too long; the surface is too smooth; surface treatment is too shallow; coating is not cured, easy to fall off when processing;
Solution: surface thoroughly cleaned; surface treatment immediately construction; surface grinding digestion, processing into a screw or dovetail groove; the scratch at the depth of more than 2mm; improve the curing temperature, to extend the curing time;
5. Coated rough: with glue mixed uneven; repair agent failure, deterioration; coating over the application period; construction temperature is too low, the viscosity of the patch is too large.
Solution: mixing to be uniform; strict attention to the storage period; within the specified time, the construction is completed; sticky surface to warm up or improve the construction environment temperature.
6. Joint dislocations crack: place improper placement, heating too early glue flow; glue volume; pressure pressure too early; no clamping limit.
Solution: put the locations, the initial solidification and then ladder heating; before curing check, lack of glue at the end; early curing, viscosity increases in the pressure; with fixture positioning.
