PurificationWorkshop decoration requirements
1. The buildings of the workshop should be durable, easy to maintain, easy to clean, and have a structure that can prevent contamination of food, food contact surfaces and inner packaging materials (such as the invasion, habitat, reproduction, etc. of harmful animals).
2. In order to prevent cross-contamination, personnel passages and material transportation channels should be set up separately, and each passage should be equipped with insect-proof facilities such as air curtains (i.e. air curtains) or two-way spring doors and electronic fly (mosquito) devices.
3. The gaps around the pipes, doors and windows and ventilation ducts leading to the outside world shall be completely filled, and all windows, vents and fan openings shall be equipped with protective nets.
4. The height of the production workshop should be able to meet the requirements of process and hygiene, as well as the needs of equipment installation, maintenance and maintenance.
How to achieve dust-free production workshopPurification
In order to obtain the purification effect required by the process, the dust-free production workshop must reasonably understand the required process, purification level and special requirements in the workshop before the construction can be implemented. The most important thing is to correctly use the dust-free production workshop and reasonably maintain the management system of the workshop, so that the dust-free production workshop can achieve a good purification effect and meet the required purification degree.
Dust-free purification workshop purification decoration construction requirements
1. According to the requirements of GMP specifications, the design and installation of the clean room should be considered to avoid the parts that are not easy to clean in use.
2. The gaps between the building decoration and doors and windows should be sealed on the front.
3. The ground treatment is self-leveling ground treatment, and the 2mm thick PVC floor is laid.
4. Pay attention to the protection of the completed working surface, and do not cause the pollution of plate dents, dark cracks and surface decoration due to impact, knocking, trampling, and watery operations.
5. All partition walls, accessories, ceiling fixing and hanging parts can only be connected to the main structure, and cannot be cross-mixed with equipment and pipeline brackets to prevent the loosening of decorative materials and dust falling off due to micro-earthquakes.
6. According to GMP certification inspection standards, interior decoration should meet the following requirements:
Materials with good air tightness and low deformation under changes in temperature and humidity should be selected.
The surface of the wall and ceiling should be smooth, smooth, ash-free, dust-free, corrosion-resistant, impact-resistant, easy to clean, and reduce concave and convex surfaces. The junction of the wall and the ground is made into a radius equal to 50 mm. The color of the wall should be harmonious, elegant, and easy to identify contaminants.
Doors and windows should be straight with the inner wall, and the structure should fully consider the sealing of air and water vapor, so that polluting particles are not easy to penetrate from the outside and prevent condensation due to the temperature difference between indoor and outdoor. Gaps such as internal doors, internal windows, and partitions between rooms with different levels of purification in the room must be sealed.
7. The amount of dust generated in the construction operation should be controlled during construction, especially the hidden spaces such as the ceiling and the inside of the sandwich wall, which must be cleaned at any time.
8. In the room where the high-efficiency filter has been installed, the decoration operation with dust cannot be carried out.
