What Factors Affect the Compressive Strength of Machine Made Sandwich Panel? There are many main factors, the most important of which are three factors: the organization, the nature of the cement and the direction of the pressure.

1. Organization

In terms of crystal particle size, some fine-grained rocks or aphanitic rocks tend to have greater compressive strength than coarse-grained rocks. Due to the different types of natural rock used in the production process of the machine-made rock wool board, the crystallization particle size of the produced machine-made rock wool board is also different, but the crystallization particles of the machine-made rock wool board produced by basalt are smaller and are also resistant High compressive strength.

2. Properties of cement

The properties of the cement greatly affect the compressive strength of the insulation material. The adhesive used in the production process of the machine-made rock wool board, according to the structure of the rock wool board, can be known that the machine-made rock wool board has a bonding layer, an insulation layer, Composed of plastering layer, a facing layer and accessories, the bonding layer and plastering layer use adhesives, so their compressive strength should be relatively good, but it should be noted that the quality of the adhesives is different So the actual situation is also different.

3. The direction of pressure

The compressive strength of machine-made rock wool boards also depends on the direction of extrusion stress. The machine-made rock wool board has layers. If the direction of the stress is perpendicular to the layer, the machine-made rock wool board has a higher compressive strength.
