In the woodworking machinery industry, the use of woodworking plywood is essential. Simply put, the proper choice and use of products can turn rot into magic. What are the different aspects to pay attention to when using woodworking plywood?
A detail of woodworking plywood products: temperature
The just-in-time measurement system works in living environments with different temperatures and wood surface temperatures. The temperature determines the speed of crosslinking reaction to a certain extent.
At different temperatures, plywood adhesive can understand different available time; After the time is mixed within 30 minutes (that is, use, the earlier the better), and in the winter a certain temperature is relatively low, the use time of woodworking plywood is 60 minutes.
Woodworking plywood products need to pay attention to some details two: wood moisture content
Under normal circumstances, after the natural moisture return of the dry substrate, the water content of the substrate should be controlled between 7%-12%.
When the moisture content of the substrate is less than 7%, the phenomenon of excessive permeability of the substrate and lack of adhesive surface may occur, resulting in the cracking of the substrate.
If the water content of the substrate is too high, it may lead to poor air permeability, unable to form glue nails, incomplete cross-linking reaction, and the phenomenon of opening glue.
Woodworking plywood products need us to pay attention to the details of the third: the actual economic development of the substrate itself
The bonding surface of the base material has no processing defects such as "nibbling head and biting tail", the square degree of the base material is good, and the bonding surface of the base material has no "planing mark, saw mark, carbonization" and other phenomena. Effective bonding is strictly prohibited between substrates whose bonding surface has been contaminated by grease, dust, etc.
The above is a brief introduction to the details of the use of woodworking plywood products, I hope to help you.
