Three factors that determine the quality of plywood

In the production of plywood, almost every process affects the quality of plywood gluing to varying degrees. In order to facilitate the purchase of consumers, the treasures of healthy home plates are summarized as follows:

 

First, the quality of the adhesive

It is characterized by the properties of the synthetic resin adhesive for the adhesive, the combination of the components and the rubberizing process.

In recent years, many domestic researches have been carried out on the various components of the plywood and the rubber mixing process. This not only saves a lot of chemical raw materials, reduces the cost of the products, but also improves the performance of the products. This is a performance of technological progress. The synthetic resin used in the production of the health plate is excellent in performance, has sufficient bonding strength, the distribution ratio of each group of adhesives is reasonable, the prepared adhesive has stable performance, the resin content and viscosity are suitable, and the active period is long enough to ensure normal operation. And the indicators of the products meet the requirements.

  

Second, the quality of the board

The quality of the veneer, especially its surface state, has a great influence on the bonding strength.

The quality of the board of Baibao is paid enough attention in the preparation of the wood section and the cutting process of the veneer. The wood softening treatment is well performed, and the conditions of the rotary cutting are controlled to make the indexes of the veneer at the optimum value. The moisture content and flatness of the veneer are also guaranteed.

  

  Third, plywood gluing

Before the rubber pressure, we should pay attention to master the two aspects of the amount of glue and slab aging. The amount of glue is too large, and the cost is high; and the glue layer is too thick, the internal stress is increased, and the glue is easy to penetrate; the amount of glue is too small, which is not conducive to the infiltration of the glue, and the glue layer may be incomplete.

Baibao's plywood has always been suitable for the length of aging, and makes reasonable changes with climate change. The core plate is completely expanded, and the lamination of the core plate and the separation of the seam are reduced.

  

In addition, Baibao's plywood adopts new technology and new equipment, such as high-efficiency jet veneer dryer, core panel stitching machine and core board leveling machine to realize sizing, blanking, pre-pressing and hot pressing continuous operation. The use of mechanized loading and unloading, quick closing hot press, etc., accurately control the process conditions, so that product quality is more assured.
