Cardboard Interlayer Peel Tester - Technical Literature

Cardboard interlayer peel tester - technical literature Interlayer bond strength refers to the ability of paper or cardboard to resist interlayer separation, which is a reflection
of the internal bonding ability of paper.

Low strength will lead to paper and cardboard, when printing with viscous inks, there will be brushing problems, too high strength will bring difficulties to the production and processing of paper, while increasing the company's costs
.

Evaluation method 1, zero distance bonding index (BI): by measuring the zero-distance tensile resistance of dry and wet paper strips, the percentage of effective tensile strength improvement in bonding is defined as the bonding index
.

2.
Calculated by measuring Z-direction strength (such as Scott bonding), the energy of tearing paper in Scott bonding is determined
by the reduction of the pendulum angle.

When the fibers of the hand-copied paper are arranged in the xy plane, the energy consumed is mainly used for the binding between the fibers, and the fiber length and the strength of the fiber itself have no effect on
the Scott bonding value.

Detection principle Double-sided adhesive-specimen-double-sided adhesive combination forms a sandwich structure, which is pressed between a metal anvil and an aluminum block, the structure
.

Hit the inner surface of the upper part of the aluminum block with a pendulum, flip the aluminum block, and destroy the specimen
in the Z direction.

The energy
absorbed during the destruction of the specimen is calculated by determining the high position of the swing.

Factors influencing the measurement result include: potential energy when placed in a locked state; Swinging in a high position; The energy required to knock off an aluminum block without a specimen; Friction loss; internal vibration loss of the pendulum; viscosity
of double-sided adhesive.
