Expansion injection angle code for the central column
1. The expansion adhesive corner code for the center column is a special adhesive used to fill between the corner code and the profile, called group corner adhesive. The central column connector, the central column expansion injection glue corner code, is like a traditional mortise and tenon connection structure. Before connection, high temperature resistant waterproof glue is usually applied to the contact surface between the mortise and tenon joints. This can make the connection more secure and less likely to loosen even under impact; This corner assembly process includes two special technologies: one is the expansion tension fixing technology, and the other is the injection sealing technology. After the injection of glue, it was completely sealed with glue from the inside of the cavity. The gap between the corner code and the profile cavity is completely sealed.
2. This can make it more sealed by filling. The glue used for doors and windows is functionally similar to the traditional Chinese mortise and tenon structure wood glue, both aimed at enhancing the firmness and sealing of windows. After injection molding and curing, it has high hardness, strong strength, good toughness, low elasticity, and excellent waterproof performance. It can make the bonding between the corner bracket and the profile cavity wall a tough connection, thereby repairing and reducing various deformations and cracking conditions, effectively solving problems such as leakage at the corners of doors and windows.
