Description
Technical Field

Background
The composite board is generally divided into a metal composite board, a wood composite board, a color steel composite board, a rock wool composite board and the like, wherein the composite board needs a water resistance test, and the water resistance refers to the capability of resisting water damage of the material. The water damage to the material performance is reflected in different aspects, and the most obvious performance is that the mechanical property of the material is reduced. The water resistance is generally expressed by a softening coefficient, which is calculated by the following formula, wherein Kf is the softening coefficient of the material, f1 is the compressive strength of the material in a water absorption saturated state, MPa, and f0 is the compressive strength of the material in a dry state, MPa. After the material absorbs water, the bonding force between the internal particles is weakened, so that the strength of the material is reduced to different degrees. The greater the softening coefficient, the greater the resistance of the material to water damage, i.e. the greater the water resistance. The softening coefficient is between 0 and 1. The softening coefficient is an important criterion for selecting a water-resistant material. The softening coefficient of the material directly used in water or severely affected by moisture is not lower than 0.85, and the softening coefficient of the material lightly affected by moisture is not lower than 0.75. Materials having a softening coefficient of more than 0.85 are generally considered to be water-resistant materials and can be used as waterproof materials.
