Thermosetting polystyrene board is a common building material, and its specification coefficient is one of the key factors determining its performance and use. This article will provide a detailed introduction to the specification coefficients of thermosetting polystyrene board to help everyone better understand and use this material.

Firstly, we need to understand what thermosetting polystyrene board is. Thermosetting polystyrene board is a kind of rigid foam plastic made of polystyrene resin and other additives by hot pressing process. It has excellent properties such as lightweight, thermal insulation, thermal insulation, sound absorption, and earthquake resistance, and is widely used in fields such as construction, ships, and airplanes.

The specification coefficients of thermosetting polystyrene board mainly include the following aspects:

1. Density coefficient: Density coefficient refers to the ratio of the density of thermosetting polystyrene board to its weight. The magnitude of density coefficient directly affects the insulation performance and strength of thermosetting polystyrene board. Generally speaking, the higher the density coefficient, the better the insulation performance of thermosetting polystyrene board, but the lower the strength; The smaller the density coefficient, the higher the strength of the thermosetting polystyrene board, but the poorer the insulation performance.

2. Compressive strength coefficient: The compressive strength coefficient refers to the ratio of the compressive strength of thermosetting polystyrene board to its density. The magnitude of compressive strength coefficient directly affects the bearing capacity of thermosetting polystyrene board. Generally speaking, the higher the compressive strength coefficient, the stronger the bearing capacity of thermosetting polystyrene board.

3. Tensile strength coefficient: The tensile strength coefficient refers to the ratio of the tensile strength of thermosetting polystyrene board to its density. The magnitude of the tensile strength coefficient directly affects the deformation resistance of thermosetting polystyrene board. Generally speaking, the higher the tensile strength coefficient, the stronger the deformation resistance of thermosetting polystyrene board.

4. Thermal conductivity: Thermal conductivity refers to the thermal conductivity of thermosetting polystyrene board at unit thickness and unit temperature difference. The magnitude of thermal conductivity directly affects the insulation performance of thermosetting polystyrene board. Generally speaking, the lower the thermal conductivity, the better the insulation performance of thermosetting polystyrene board.

5. Water absorption rate: Water absorption rate refers to the percentage increase in the mass of thermosetting polystyrene board after absorbing water. The water absorption rate directly affects the service life and insulation performance of thermosetting polystyrene board. Generally speaking, the lower the water absorption rate, the longer the service life of thermosetting polystyrene board and the better its insulation performance.

Overall, the specification coefficient of thermosetting polystyrene board is a key factor determining its performance and application. When selecting and using thermosetting polystyrene board, the appropriate specification coefficient should be chosen according to the specific usage environment and requirements. At the same time, regular inspection and maintenance should be carried out on the thermosetting polystyrene board to ensure its good performance and service life.
