Purification panels are a type of building material commonly used in environments with stringent requirements-such as cleanrooms, laboratories, and medical facilities-primarily for constructing partition walls and suspended ceilings. Their core function lies in leveraging specific material properties and structural designs to deliver performance attributes such as moisture resistance, flame retardancy, and compressive strength, thereby meeting the unique cleanliness and safety demands of these specialized settings.
Structural Composition and Material Properties:
A purification panel is a composite structure consisting of two outer layers of steel sheeting bonded to an inner core material. The steel sheets, typically 0.5 mm in thickness, provide structural support and ensure surface flatness. The core material predominantly consists of expanded polystyrene (with a bulk density of 80 kg/m³), which is introduced via a self-foaming process to create a uniform, closed-cell pore structure. This specific structure serves a dual purpose: it ensures the panel remains lightweight (exemplified by the 1150-type specification with a 100 mm thickness) while simultaneously utilizing the closed-cell pores to block the transmission of moisture vapor and flames, thereby delivering effective moisture resistance and flame retardancy. The panels achieve an "AAA" fire-resistance rating-fully compliant with national standards-and are capable of effectively retarding the spread of fire.
Core Performance Attributes and Applicable Scenarios:
The performance advantages of purification panels are manifested in three key areas: First, moisture resistance-the closed-cell structure of the polystyrene core results in an extremely low water absorption rate, making the panels ideal for environments with high humidity levels. Second, flame retardancy-the synergistic interaction between the core material and the steel sheets enables the panels to satisfy the rigorous fire safety standards required in cleanroom environments. Third, compressive strength-with a compressive strength of 200 MPa, the panels can withstand specific external forces without undergoing deformation that could compromise the integrity of the clean environment. Typical application scenarios include partition walls and suspended ceilings in electronics manufacturing workshops, food processing plants, and hospital operating rooms-areas where strict control over dust and microbial contamination is essential, alongside requirements for fire safety and ease of cleaning.
