With the continuous development and progress of the social and economic level, the use of various plates is extremely extensive, especially in the decoration industry, the scope of its use is wider, and it continues to provide rich raw materials, and sufficient human resources have brought advanced productivity to these manufacturers, but also pay attention to the rational use of plates.
When plywood is used as decoration, the requirement is that its surface should be smooth, and the grain must be clear, which is the requirement for its decorative effect, and in terms of its fire resistance and moisture resistance, it must meet certain specifications to ensure that it can have a longer time life, plywood and can ensure our safety. When the plywood is used as a building material, it is necessary to ensure that the thickness of these materials is moderate, the board density is reasonable, and the building plywood has certain requirements for the decorative effect, so its finishing nature must be comprehensive.
The material of the plywood is very uniform and detailed, and the texture of the wood is arranged in a certain way, so that the joint and the edge of the board are balanced with each other, without burrs and planing marks, making the product achieve not only a beautiful appearance, but also a more practical feature.
Poplar plywood is one of the types of plywood, and plywood is one of the first ways to save wood, it is by the poplar wood segment spinning cut into veneer or by wood square planing cut into thin wood, plywood manufacturers and then use adhesive glued into three or more layers of sheet material, usually with odd layers of veneer, and the adjacent layer of poplar veneer fiber direction straight glued to each other. From the point of view of saving resources, as much as possible.
But from the environmental protection point of view to remind us to pay attention to, plywood will use a lot of glue, inferior glue adhesion of the board will have formaldehyde problems, to pay attention to the environmental problems of the board, it is best to let the business supply the testing certificate of the board before the purchase.
Due to the continuous development and progress of the social level, plywood is widely used in the decoration industry, and the hot grinding section is an important production process for plywood manufacturers, which has a lot to do with the good quality of the density board.
If in the hot grinding section due to improper operation, violation of the process rules, do not operate according to the requirements of the process parameter file, it will cause poor fiber quality, fiber shape or moisture content does not meet the relevant process requirements and other problems, if not pay close attention to the drying inlet and outlet temperature, resulting in fiber moisture instability, fiber moisture content continuously exceeds the process provisions, resulting in product grade degradation, etc. When the hot grinding equipment fails to stop, the cooking tank must be empty, and the workshop director must be reported to sign for confirmation when it cannot be empty.
