What are the types of Sandwich Panels for cleanroom?

Types of Sandwich Panels for cleanroom

Sandwich panels for cleanrooms are specialized components designed to provide structural support while maintaining high levels of cleanliness and controlled environments. The main process types of sandwich panels used in cleanrooms include:

• Handmade Sandwich Panels also named Manufactured Sandwich Panels are constructed manually by workers. While this method offers some customization, it can lead to slight variations in dimensions and potentially less consistent quality. The panels may utilize a galvanized steel frame or rely solely on adhesive bonding between the outer sheets and the core material, affecting overall strength and rigidity. Core material options might be limited due to manual processing, with rock wool and polystyrene being commonly used. Installation may require additional connector elements, such as “+” shaped profiles, which can increase installation time and potentially create small gaps. However, handmade panels offer greater flexibility for on-site modifications, such as cutting panels to specific dimensions. This flexibility requires skilled workers and may compromise the panel’s integrity. Handmade sandwich panels are suitable for smaller projects or situations where on-site customization is needed, such as cleanrooms (especially ceilings), temporary structures, or applications with specific size requirements.
• Machine-made sandwich Panels also named prefabricated sandwich Panels are produced in factories using automated machinery, which ensures consistent quality, precise dimensions, and high production volume. These panels typically feature a prefabricated metal frame sandwiched between two outer sheets, providing additional structural rigidity and strength. Due to specialized machinery, they offer a wider variety of core materials, such as rock wool, polyurethane foam, and polystyrene. The panels often utilize male-female interlocking edges, facilitating quick and easy installation with minimal gaps. Customization is generally limited to size and core material selection because of the prefabricated components. Machine-made sandwich panels are ideal for large-scale projects that require consistent quality, fast installation, and a range of core materials. They are commonly used in warehouses, factories, cold storage facilities, and prefab buildings.

How many types of sandwich panel core material?

• Paper Honeycomb Cleanroom Panel:Carbon honeycomb board is a new high-tech building material, that has gradually replaced traditional composite clips such as rock wool, EPS, PU, and so on. Core plate. The honeycomb board has better performance than the traditional sandwich board: higher flame retardancy, lighter self• weight, and stronger load-bearing capacity. The sound insulation effect is better and the environmental protection performance is stronger. Carbon honeycomb board has been widely used in electronic, and biological. food, pharmaceutical, hospital, military cleaning, etc.Net construction industry is the preferred product of modern architecture.
• Hollow glass magnesium plate core material/MGO Cleanroom Panel:a high-grade fireproofing material of composite plate at present, which meets the requirements of fire protection. Magnesium sulfate glass-magnesium plate is a perfect substitute for the original magnesium chlorideglass-magnesium plate to solve the halogenation phenomenon of corroded steel plate and aluminium alloy caused by chloride ion release. The product has the characteristics of high strength, high bearing capacity, impact resistance, high temperature resistance, quick installation and beautiful appearance.
• Rock Wool Cleanroom Panel:It is suitable for projects with high requirements for fire prevention. Rock wool fibers are perpendicular to the metal face plate, and high density strip rock wool is staggered along the length of the plate, which ensures that the rock wool Purification board has good bearing capacity. Rock wool sandwich board has a significant effect on reducing noise transmission,especially in areas with high requirements for sound insulation. Use grade A of Fireproof rock wool and it has better sound insulation and heat insulation effect.
• MGO Rock Wool Cleanroom Panel:Add Rockwool to fill the Hollow of glass magnesium plate core material. It is obvious improve for fire prevention. Rock wool fibers are perpendicular to the metal face plate, and high density strip rock wool is staggered along the length of the plate, which ensures that the rock wool Purification board has good bearing capacity. Rock wool sandwich board has a significant effect on reducing noise transmission,especially in areas with high requirements for sound insulation. Use grade Aof Fireproof rock wool and it has better sound insulation and heat insulation effect. .
• Magnesium Oxysulfide Purification Cleanroom Panel:Magnesium oxysulfide fireproof insulation board (commonly known as hollow magnesium oxysulfide board) is a special core material for color steel purification board. It is made of magnesium sulfate, magnesium oxide and other materials by lamination method, after pressing and moulding. It is a new type of clean and heat preservation product with green and environmental protection. Compared with other types of color steel plate core materials, it has the advantages of fire prevention, waterproof, thermal insulation, bending resistance, heat insulation, sound insulation, non-toxicity, light weight and neat appearance. It makes up for the shortcomings of some color steel purification plate core materials on the market at present, such as strength, bending resistance, bearing capacity, Excellentstability, especially suitable for some indoor and outdoor partition walls and ceiling for specific geographical characteristics.
• Propor Clean room Panel:PROPOR (No Aging) is a new type of thermal insulation material that utilizes particle fire isolation membrane technology. It employs copolymer modification to impart fire-resistant properties to EPS (expanded polystyrene) beads, and applies micro-phase composite technology to form a fire isolation membrane on the surface of each organic particle, transforming each particle into an independent organic particle fireproof unit. When exposed to flames, PROPOR forms a continuous honeycomb-like structure that provides thermal insulation and fire blockage, preventing combustion.
  PROPOR (No Aging) A-grade fireproof thermal insulation panels can be customized to suit specific project designs, functional requirements, and actual construction conditions, offering high operability. No Aging, also known as “True Gold Board,” is a new type of modified foam board with an A2-grade fireproof core. It provides both thermal insulation and heat insulation, making it widely applicable for partition walls and ceilings in cleanrooms in industries like electronics, food, and beverage, where thermal insulation is essential. Its lightweight nature facilitates easy installation.
• Silica Cleanroom Panel:Silica slabs are mainly made of polystyrene, which is originally a good low thermal conductivity material, and then extruded to form a compact honeycomb structure. Thereby, the heat conduction is effectively prevented, which has the characteristics of high thermal resistance and low linear expansion rate. The difference between rock wool board and rock wool board lies in the temperature resistance, thermal conductivity, and resistance of the board. Temperature limit. Using silica slabs can not only meet the requirements of heat preservation and energy saving but also prevent fire.
• Polyurethane(PU) Cleanroom Panel:PU: PU is short for polyurethane, which is also called Urethane rubber or spring rubber. The full name is polyurethane or isocyanate polymer. Polyurethane is an elastomer between plastic and rubber with a unique combination of their excellent performances.

Conclusion
Both types of sandwich panels have their own advantages and are suited for different applications. Machine-made sandwich panels are ideal for large-scale, cost-sensitive projects requiring uniform quality, while handmade sandwich panels are better suited for customized, high-precision applications where specific design and material requirements are crucial.
