Quality inspection of all birch plywood substrate
- The base material of all birch plywood is the same material, with good stability.
two
The density of all birch plywood substrate is higher than that of eucalyptus, with less water absorption and lower coefficient of thermal expansion and contraction.
three
All birch plywood substrate phenolic adhesive is formaldehyde free and environmentally friendly.
four
The base material of all birch plywood, phenolic adhesive, has strong moisture resistance and will not break through the adhesive layer; Ordinary melamine adhesive on the market is not environmentally friendly and has strong water penetration, which can penetrate the adhesive layer and cause the wood skin to turn black.
Disadvantages,
- All birch plywood based furniture has poor fiber shear resistance and is prone to “even stubble breakage”, so birch furniture is not wear-resistant and has weak tensile resistance.
- The base material of all birch plywood has patterns at its roots and joints, and has high moisture absorption. It is prone to cracking and warping when dry, so birch furniture should not be too dry for indoor environment requirements. Not wear-resistant, this is one of the drawbacks.
- The base material of all birch plywood is juicy and often deforms after completion, so it is rare to see tables and chairs made entirely of birch wood.
