Standard Installation Steps for Cleanroom Sandwich Panel
? Step1: Site Preparation, Survey & Marking before Installing Cleanroom Sandwich Panel Before installing cleanroom sandwich panel, the construction team must complete site inspection and flatness verification of the base floor and structural frame. Uneven ground is one of the primary causes for poor assembly of cleanroom sandwich panel. Workers need to measure the internal dimension of the clean zone accurately and draw positioning lines on the floor and wall to define the layout of cleanroom sandwich panel walls and ceilings.
SAMZOON factory will pre-cut cleanroom sandwich panel strictly according to the construction drawings provided by purification engineering clients. Pre-cutting minimizes on-site cutting work of cleanroom sandwich panel. On-site cutting will generate metal dust and debris, which easily contaminate the clean area and scratch the protective coating of cleanroom sandwich panel. If on-site cutting of cleanroom sandwich panel is unavoidable, workers must take dust collection and surface protection measures to avoid damaging cleanroom sandwich panel.
? Step2: Fix the Supporting Keel Framework for Cleanroom Sandwich Panel The keel frame is the load-bearing foundation of cleanroom sandwich panel. The frame must be level, vertical and firmly anchored to the building structure. If the keel is tilted or loose, the installed cleanroom sandwich panel will be misaligned, forming irregular gaps between adjacent cleanroom sandwich panel. Uneven stress will also make cleanroom sandwich panel warp gradually over time.
All keel installation positions should match the pre-marked layout lines. The spacing of keels is determined by the specification and thickness of cleanroom sandwich panel, especially when cleanroom sandwich panel is used for ceiling. Ceiling-mounted cleanroom sandwich panel has stricter load requirements, so keel spacing must follow the technical specification of cleanroom sandwich panel. SAMZOON technical team can provide keel design suggestions matched with SAMZOON cleanroom sandwich panel for purification projects.
? Step3: Assemble and Fasten Cleanroom Sandwich Panel Start assembling cleanroom sandwich panel one by one along the positioning line. Cleanroom sandwich panel adopts modular interlocking structure, so each cleanroom sandwich panel needs to be locked tightly with adjacent panels by dedicated connectors. During assembly, workers must handle cleanroom sandwich panel gently to prevent scratches, dents and coating damage on the surface of cleanroom sandwich panel. Any scratch will break the protective layer of cleanroom sandwich panel and reduce its anti-corrosion and dustproof capacity.
When installing cleanroom sandwich panel for wall corners, door openings and observation windows, special customized cutouts of cleanroom sandwich panel are required. SAMZOON can prefabricate these special-shaped cleanroom sandwich panel components in factory, greatly simplifying on-site assembly and reducing the risk of damaging cleanroom sandwich panel during processing.
? Step4: Joint Sealing, the Most Critical Process of Cleanroom Sandwich Panel Installation Seam sealing directly decides whether the cleanroom can meet cleanliness standards. All gaps between cleanroom sandwich panel, and gaps between cleanroom sandwich panel and doors, windows, keels must be filled with special clean-grade sealant. Poor sealing leaves hidden crevices where dust, bacteria and particles accumulate. These hidden contaminants will cause particle concentration out of limit and result in GMP inspection failure, even if the cleanroom sandwich panel itself is qualified.
Sealant should be applied continuously without breakpoints, and excess sealant needs to be smoothed neatly to avoid protrusions that collect dust. SAMZOON shares standardized sealing operation specifications for cleanroom sandwich panel with cooperation purification contractors. Our team reminds construction crews to select compatible sealant matching the surface material of cleanroom sandwich panel.
? Step5: Post-Installation Inspection & Protection of Cleanroom Sandwich Panel After all cleanroom sandwich panel is assembled and sealed, comprehensive inspection is required. Check the flatness of cleanroom sandwich panel wall and ceiling, verify tightness of all panel joints, and inspect the whole surface of cleanroom sandwich panel for scratches, dents or coating damage.
After inspection, temporary protective film of cleanroom sandwich panel should be kept intact until the whole purification construction is finished, to prevent subsequent painting, welding and other operations from damaging cleanroom sandwich panel. SAMZOON offers full-cycle remote technical support for cleanroom sandwich panel installation, and supports urgent delivery of cleanroom sandwich panel for projects with tight construction schedules.
