How to do wood-based panel tensile and bonding tests? Wood based panel gluing, static bending strength test method!

Recently, some friends asked about the test scheme of wood-based panel tensile, bonding, gluing and static bending strength. In order to let you know more about how to do wood-based panel tensile and bonding tests,   wrote this article. Let’s take a look at how to do wood-based panel tensile, bonding, gluing and static bending strength tests?

The following analysis is made on the test scheme and standard of wood-based panel bonding strength measurement and tensile strength, internal bonding strength, static bending strength and elastic modulus, nail holding force, surface bonding strength and surface bonding strength:

1. Test scheme for inner gluing (bonding) strength of wood-based panels and veneered wood-based panels

Internal bonding (bonding) strength: it is the measurement of tensile strength when the surface of the test piece bears uniformly distributed tensile force until it is broken, and it is the ratio of the maximum breaking tensile force perpendicular to the surface of the test piece to the sample area. This scheme is applicable to the measurement of internal bonding (bonding) strength performance of various wood-based panels and veneered wood-based panels.

The test methods for the internal bonding (bonding) strength of wood-based panels and veneered wood-based panels are mainly based on the provisions in GB / T 17657-2013 test methods for physical and chemical properties of wood-based panels and veneered wood-based panels.

2. Test plan for surface bonding strength of wood-based panels and veneered wood-based panels

Surface bonding strength: refers to the bonding strength or bonding quality between the shavings or fibers of the surface layer of the board and the underlying material (uncoated panel) or between the facing material and the base material (decorative panel), expressed by the ratio of the maximum breaking tension of the surface layer perpendicular to the board surface to the bonding area of the test piece. This scheme is applicable to the determination of the surface bonding strength performance of various wood-based panels and veneered wood-based panels.

The test methods for the surface bonding strength of wood-based panels and veneered wood-based panels are mainly based on the provisions in GB / T 17657-2013 test methods for physical and chemical properties of wood-based panels and veneered wood-based panels.
