GMP workshop renovation with Clean, sealed, easy to clean, and contamination-resistant. As a guiding principle, we must strictly adhere to the relevant regulatory requirements and take a holistic approach to control aspects such as material selection, node construction, and detail handling, thereby providing the foundational conditions for a stable and reliable production environment.

Material selection must meet: Corrosion-resistant, scrub-resistant, dust-free, and does not accumulate dust. basic requirements. For walls and ceilings, mechanically cleaned color-coated steel panels are preferred; these panels feature a smooth surface and excellent sealing properties, effectively reducing dust accumulation and bacterial growth. Floors should ideally be made of homogeneous, through-colored PVC flooring or epoxy self-leveling materials, which offer seamless construction, wear resistance, and anti-slip characteristics, making them well-suited to the cleaning and disinfection needs of cleanrooms. Before any material is brought onto the site, its quality certification documents must be inspected to ensure that its performance meets the requirements of the workshop environment.

Pay attention to layout and structural construction. Separation of passenger flow and logistics. To reduce cross-contamination, clearly delineate the various functional zones and establish buffer zones between clean and non-clean areas to create a reasonable pressure differential gradient. Wall, floor, and ceiling junctions feature rounded corners instead of sharp right angles, eliminating dead corners and thereby simplifying cleaning procedures. At wall joints, window and door frames, and pipe penetrations through walls, use sealants to ensure tight sealing, preventing air leakage and dust intrusion.

The installation of doors, windows, and associated fittings emphasizes both airtightness and rationality. Cleanroom doors and windows feature excellent sealing performance, with door frames securely connected to the walls and gaps between doors and windows properly sealed. Cleanroom doors open toward areas with higher cleanliness levels and are equipped with door-closing devices. Observation windows are made of transparent, clean materials that are flush with the wall surface, minimizing dust accumulation areas. Material transfer facilities are fitted with interlocking mechanisms to prevent simultaneous opening on both sides, thereby reducing the risk of cross-contamination.

HVAC and electrical systems will be implemented in coordination with the interior decoration. Purification lamps, switches, sockets, and other fixtures will be of the flush-mounted, clean-design type, featuring smooth, even surfaces that are easy to wipe clean. Conduits will be concealed as much as possible to minimize exposed connections. Supply and return air vents will be installed smoothly and securely, with tight seals at the junctions with the ceiling, ensuring proper airflow organization and meeting environmental purification standards.

Drainage and Clean Floor Drain Installation Standards: In clean areas, floor drains shall be of a clean-design type, equipped with water seals and sealing structures to prevent the backflow of odors and contamination. The floor shall be designed with an appropriate drainage slope to direct water flow toward the floor drain, thereby avoiding water accumulation in the area. The drainage pipes shall be made of corrosion-resistant materials that are easy to clean, with reliable sealing at the joints, meeting the hygiene control requirements of the workshop.

The construction process follows First top, then bottom; first rough packaging, then fine packaging. In accordance with the prescribed sequence, minimize dust generation at the construction site. Ensure smooth and orderly coordination among all work procedures, and take proper measures to protect finished products, thereby preventing scratches and damage to walls and floors. After completion of the renovation, conduct thorough inspections for sealing and cleanliness, carefully verifying key areas such as gaps and corners one by one to ensure that the overall construction quality meets the expected standards.

GMP workshop renovation is a crucial step in ensuring compliance of the production environment. By standardizing materials, strictly controlling key points, and refining processes, we can effectively enhance the cleanliness level of the workshop and provide stable and reliable hardware support for product quality control.
