Core Performance Indicators of Cleanroom Sandwich Panel
? 1. Fire Resistance of Cleanroom Sandwich Panel Fire resistance is always the primary evaluation indicator for cleanroom sandwich panel. Cleanroom sandwich panel deployed in medical buildings, pharmaceutical factories and industrial cleanrooms must comply with local fire protection codes. Many purification projects require Class A non-combustible cleanroom sandwich panel. When fire occurs, qualified cleanroom sandwich panel can block flame spread and suppress the release of toxic smoke, protecting personnel and production equipment inside the clean zone.
Not all cleanroom sandwich panel reaches Class A fire grade. Different core materials decide the fire performance of cleanroom sandwich panel. Rockwool and MGO core cleanroom sandwich panel commonly achieve Class A fire rating, while PIR core cleanroom sandwich panel usually belongs to B1 fire grade. SAMZOON cleanroom sandwich panel can be customized with different core materials to match fire requirements of each purification project. All batches of SAMZOON cleanroom sandwich panel come with complete fire test reports for project inspection and audit.
? 2. Surface Flatness & Low Particle Shedding Property The surface quality defines whether cleanroom sandwich panel meets purification standards. Qualified cleanroom sandwich panel must have compact, smooth and non-porous metal facing. If cleanroom sandwich panel has pits, cracks or uneven texture, fine dust, microorganisms and particulate contaminants will stick and accumulate on the surface. These particles will continuously pollute the clean space and cause failure in cleanliness inspection.
SAMZOON cleanroom sandwich panel adopts high-quality color coated steel or stainless steel facing. The surface of SAMZOON cleanroom sandwich panel is tightly sealed without tiny pores. Under regular wiping and cleaning, the SAMZOON cleanroom sandwich panel will not shed particles. This property makes SAMZOON cleanroom sandwich panel suitable for high-grade clean zones such as pharmaceutical GMP workshops and electronic chip dust-free rooms.
? 3. Chemical & Disinfectant Corrosion Resistance Cleanroom sandwich panel for medical, food and pharmaceutical projects faces frequent disinfection work. Disinfectants including alcohol, hydrogen peroxide and chlorine-containing agents are sprayed or wiped on cleanroom sandwich panel every day. Inferior cleanroom sandwich panel will suffer coating blistering, fading and peeling after long-time contact with these chemical disinfectants. Once the protective layer is damaged, the cleanroom sandwich panel loses its purification function.
SAMZOON provides two mainstream surface options for cleanroom sandwich panel. Color coated cleanroom sandwich panel works well for general disinfection scenarios, while stainless steel surface cleanroom sandwich panel can withstand strong, high-frequency chemical disinfection. Buyers can select proper surface material of SAMZOON cleanroom sandwich panel according to the disinfection frequency of their project.
? 4. Dimensional Stability of Cleanroom Sandwich Panel Temperature fluctuation and high humidity will cause deformation of poor-quality cleanroom sandwich panel. Warping, shrinkage or bending of cleanroom sandwich panel will create uneven gaps between adjacent cleanroom sandwich panel. These gaps become hidden places for dust and bacteria, destroying the integrity of the clean enclosure structure.
SAMZOON cleanroom sandwich panel is manufactured under stable high-pressure production process. The core material and metal facing are tightly bonded. The SAMZOON cleanroom sandwich panel maintains stable size under normal temperature and humidity changes. Before delivery, our factory inspects dimension tolerance of every batch of cleanroom sandwich panel. As Foshan local source factory, SAMZOON also offers construction technical guidance to help engineering teams install cleanroom sandwich panel correctly and avoid deformation caused by improper installation.
? 5. Mechanical Strength of Cleanroom Sandwich Panel Cleanroom sandwich panel needs enough rigidity and impact resistance. During construction and daily operation, minor collision may happen on wall and ceiling cleanroom sandwich panel. Fragile cleanroom sandwich panel will crack easily, damaging the clean enclosure. SAMZOON cleanroom sandwich panel has balanced mechanical performance, suitable for wall and ceiling application in different purification projects.
