With the development of the construction industry, more and more building plywood are used. Today, we will talk about the problems and solutions that may be encountered in the use of building plywood.
1. Glue the corners of the plywood
Due to insufficient thermal pressure during the production process, insufficient amount of glue used or poor quality glue, the corners of the building plywood are opened, and the veneer edge peeling pressure is insufficient, so special attention should be paid to these two points in the production process.
2. Bubbles or depressions appear on the surface of the building plywood
Improper selection of the panel, there are many wormholes or gaps on the surface of the panel, or the core board is not a whole core but a patchwork of ordinary board cores, resulting in the internal pressure of the construction cement during the use of the building plywood, which causes the building plywood to appear concave and convex, etc. Phenomenon, the solution lies in the selection of materials. When choosing the building plywood, the whole core must be selected. The surface of the building plywood is well-flattened.
3. Penetration glue
The glue is too thin, the amount of glue is large when the glue is applied, the cracks in the panel are too deep, the core board is not dry enough, the water content is high, and the pressure is too high to cause the glue to penetrate. The solution is to leave the template for a few days and dry it naturally. , Avoid building defacement and beautiful appearance.
4. Low strength
The strength of building plywood affects the service life and the number of uses. The main influencing factors of the low building plywood strength are the insufficient thickness of the building plywood, poor glue quality, insufficient glue quantity and short hot pressing time. Then when selecting materials, choose a thicker building plywood and check the adhesive force of the building plywood.
