Physical Parameters
Physical properties mainly include indicators such as density, moisture content, thickness, and dimensional stability. Different types of boards have significantly different densities; for example, lightweight sandwich panels have lower density, while high-density fiberboard and metal composite panels have higher density. Moisture content is usually controlled within a reasonable range to ensure that the material is not easily deformed or cracked in humid environments. Dimensional stability reflects the degree of deformation of the board under varying temperature and humidity conditions and is an important reference indicator in engineering applications.
Performance Parameters
Mechanical properties mainly include compressive strength, flexural strength, tensile strength, and impact toughness. High-strength boards can withstand greater external forces without failure and are suitable for structural load-bearing and industrial equipment applications. The mechanical properties of boards made of different materials vary significantly; metal and composite boards generally have higher overall strength, while wood-based boards emphasize a more balanced overall performance.
Functional Parameters
Functional performance is an important evaluation indicator for engineering special boards, including fire resistance rating, thermal conductivity, sound absorption coefficient, and corrosion resistance. Fire resistance rating determines a material's safety performance under high-temperature conditions, thermal conductivity is used to evaluate its thermal insulation effect, sound absorption coefficient reflects its acoustic performance, and corrosion resistance determines its service life in chemical or humid environments. These parameters collectively determine the applicable scope and engineering value of the board material.
