Fire partitions refer to facilities installed inside buildings to prevent the spread of fire, protect the safety of personnel and property.    
Fireproof partitions, also known as fire-rated compartment elements, are critical architectural features in buildings designed to prevent the spread of fire and smoke, thereby ensuring the safety of occupants and allowing for effective rescue operations. These partitions can be either vertical, such as walls and partitions, or horizontal, like floors and ceilings, and they form boundaries that resist the spread of fire.Here is a detailed introduction：
1.Temperature Control: Insulation in fire partitions is designed to prevent the temperature on the unexposed side (the side away from the fire) from rising significantly. This is important because if the temperature on the unexposed side gets too high, it could cause combustible materials in the adjacent non-fire compartment to spontaneously ignite, spreading the fire even before flames or hot gases penetrate the partition.
2.Fire Resistance Rating: The fire resistance rating of partitions, often expressed in minutes and usually in multiples of 30 minutes, also considers the insulation property. For instance, a partition that can keep flames and high temperatures at bay for at least 60 minutes is labeled as 'EI' 60, indicating it meets both integrity (E) and insulation (I) criteria.
3.Material Composition: The chemical composition of insulation materials plays a significant role in their fire-resistant properties. Materials like mineral wool and fiberglass, due to their inorganic nature, inherently resist combustion and provide reliable protection against fire hazards.
4.Thermal Insulation Effect: Fireproof partitions can be fixed on the surface of structures, such as steel shells, to provide a noticeable fire insulation effect. The thicker the fireproof board, the more pronounced the thermal insulation effect, with the maximum temperature of the steel shell having a quadratic relationship with the thickness of the fireproof boards.
5.Preventing Fire Spread: The insulation function of fire partitions is not just about containing the fire within one compartment; it also helps to prevent the spread of fire to adjacent compartments by controlling temperature rise, thus maintaining the integrity of the structure and safety of the occupants.
6.Safety and Comfort: Good partition insulation ensures a safer and more comfortable indoor environment by providing fire safety along with soundproofing and impact resistance.
In summary, the insulation function of fireproof partitions is vital for maintaining the structural integrity of a building during a fire, preventing the spread of fire to non-fire compartments, and ensuring the safety of the building's occupants.
