What are the factors that affect the quality of special-shaped steel formwork

In construction engineering, special-shaped steel formwork is a common mold, which is mainly used to make special-shaped buildings. This kind of template is usually customized, so it has high requirements for its own quality. So what are the factors that affect the quality of special-shaped steel formwork? Steel formwork manufacturers believe that these problems mainly exist.

1. Adhesive quality: mainly reflected in the performance of synthetic resin adhesive used for adhesive, the coordination of each component and the glue mixing process.

2. Substrate quality: The quality of the veneer, especially the surface state, has a great influence on the bonding strength of the special-shaped steel template. Therefore, full attention should be paid to the preparation of wood section and the veneer rotary cutting process. The wood softening treatment should be done well, the rotary cutting conditions should be controlled well, and the moisture content and flatness of the veneer should be paid attention.

3. Aging time: The aging time should be appropriate and can be reasonably changed with climate change. To realize the entire core board, reduce the core board delamination and joint separation, pay attention to the secondary and decompression speed of the rubber strip, especially when the slab has more moisture.

4. Adhesive force of steel formwork: Before gluing, attention should be paid to the two links of gluing amount and slab aging. The amount of glue is too large, the cost is high, the glue layer is too thick, the internal stress increases, and it is easy to seep glue; the amount of glue is too small, which is not conducive to glue infiltration, and the glue layer of the special-shaped steel template will be incomplete.
