How to repair curtain walls of different materials?

Building curtain wall as the outer protective structure of the building, its service life will directly affect the service life of the building . Therefore, in addition to strengthening the quality of the project, it is also necessary to strengthen the post-maintenance of the building curtain wall.

How to repair curtain walls of different materials to extend the service life of the building? Yufeng will give you a professional answer.

seven-step detection method

First check

Sampling inspection on the pull-out resistance of the rear embedded parts (anchors) before installation

Second step detection

Silicone building (weather-resistant) sealants should be tested for compatibility with the materials in contact before use<span style="font-size: 16px; /span>

The third step of detection

Silicone structural sealant should be tested for compatibility with its contact materials and peel adhesion test before use , And should re-examine the Shore hardness and the tensile bonding properties in the standard state. Imported silicone structural seals should have a commodity inspection report

The fourth step of detection

The two-component silicone structural sealant consists of two components: a base and a curing agent. Before use The homogeneity (butterfly) test and the pull-off (plastic cup) test should be carried out to check the degree of mixing of the structural adhesive and whether the mixing ratio of the two components of the structural adhesive is correct.

The fifth step of detection

processed hidden frame and semi-hidden frame glass plates, randomly selected 1% for peeling test to test the structure The curing degree of the adhesive and the bonding strength between the structural adhesive and aluminum ore

The sixth step of detection

Aluminum-plastic composite panels should undergo peel strength inspection

The seventh step of detection

Test of bending strength, radioactivity and frost resistance of stone panels. Strength test of structural adhesive for stone curtain wall and pollution test of sealant
