Polystyrene board is a commonly used building material with excellent insulation performance and corrosion resistance, and has been widely used in the field of construction. According to different production processes and uses, polystyrene boards can be classified into different categories. In this article, the integration of insulation and decoration will provide a detailed introduction to the classification of polystyrene boards.

Firstly, according to the production process of polystyrene board, it can be divided into two types: extruded polystyrene board and foamed polystyrene board. Extrusion polystyrene board is a production process that involves heating and melting polymer polystyrene particles, and then using an extrusion mold to produce the board. This polystyrene board has a smooth surface, uniform density, high mechanical strength, and thermal insulation performance. Foamed polystyrene board is made by adding foaming agent into polystyrene particles, heating and expanding to form foam, and then molding. This polystyrene board has low density and good sound insulation and thermal insulation properties, making it suitable for thermal insulation of walls and roofs.

Secondly, according to the purpose of polystyrene board, it can be divided into two types: building insulation board and packaging polystyrene board. Building insulation board is mainly used for thermal insulation of building exterior walls, which can effectively reduce the temperature difference between inside and outside the building and improve indoor comfort. This type of polystyrene board usually has good thermal insulation performance and durability, and is an important material for building energy conservation. Polystyrene board for packaging is mainly used to package fragile items such as electronic products, glassware, etc., which can effectively protect items from external collisions and compression.

In addition, based on the density and hardness of polystyrene board, it can be divided into three types: low-density polystyrene board, medium density polystyrene board, and high-density polystyrene board. Low density polystyrene board is suitable for packaging and interior decoration due to its lightweight and excellent shock absorption performance. Medium density polystyrene board has moderate density, high strength and hardness, and is suitable for fields such as building insulation and production molds. High density polystyrene board has a high density, high hardness, and good mechanical properties, making it suitable for making high-strength structural materials.

Overall, polystyrene board is a multifunctional building material that can meet the needs of various purposes according to different classification standards. With the advancement of technology and continuous innovation in material technology, the application scope of polystyrene board will become increasingly widespread, providing more possibilities for the development of the construction industry. I hope that in the future, more people will pay attention to and value the research and application of polystyrene board, bringing more benefits to our lives and environment.
