Cleanliness refers to the degree of dust content in the air environment. In general, it refers to the number of particles of a certain size or larger contained in a unit volume of air. High dust content leads to low cleanliness, while low dust content leads to high cleanliness.

To achieve good cleaning results in a clean room, it is not only necessary to focus on adopting reasonable air conditioning purification measures, but also to require corresponding measures from the process, construction, and other professions: not only should there be reasonable design, but also careful construction and installation that comply with regulations, as well as correct use of the clean room and scientific maintenance and management. In fact, it is difficult to achieve ideal cooperation between different professions, and designers find it difficult to grasp the quality of construction and installation, as well as the use and management situation, especially the latter. In terms of clean room purification measures, many designers or construction companies often do not pay enough attention to their necessary conditions, resulting in unsatisfactory cleaning effects.

1. Supply air cleanliness:

To ensure that the cleanliness of the air supply meets the requirements, the key is the performance and installation of the final filter in the purification system.

2. Airflow organization:

The airflow organization in a clean room is different from that in a general air-conditioned room. It requires clean air to be sent to the operating area first, and its function is to limit and reduce pollution to the processed materials.

3. Supply air volume or wind speed:

Adequate ventilation volume is used to dilute and eliminate indoor polluted air. According to different cleanliness requirements, when the cleanroom height is high, the ventilation frequency should be appropriately increased.

4. Static pressure difference:

Maintaining a certain positive pressure in a clean room is one of the essential conditions to ensure that the clean room is not contaminated or minimally contaminated, in order to maintain the designed cleanliness level.

Installation and use of purification workshop:

1. All maintenance components of the fabricated purification project are processed in the factory according to the unified module and series, which is suitable for batch production, stable quality and rapid supply;

2. Flexible and adaptable, suitable for installation in newly built factories as well as for the renovation of purification technology in old factories. The maintenance structure can also be combined arbitrarily according to the process requirements, and it is easy to disassemble;

3. Requires a small building area and low requirements for the decoration of earthen buildings;

4. The airflow organization form is flexible and reasonable, which can meet the needs of various working environments and different cleanliness levels;

How much does the decoration of Xinyang purification workshop cost per square meterMeasures to ensure the cleanliness and compliance of the purification workshop:

1. Purpose

(1) To ensure the quality of the cleanroom project, the construction, acceptance, and testing of the cleanroom must comply with the "Construction Organization Design", "Good Manufacturing Practice (GMP) 98", and "Cleanroom Construction and Acceptance Specification".

(2) Before the construction of the clean room, a detailed construction cooperation plan must be formulated according to the main construction procedures of the clean room, and the construction must be strictly carried out according to the construction procedures. Each process must undergo intermediate acceptance and recording.

(3) The main materials, equipment, finished and semi-finished products used in the project must comply with the design requirements and have factory qualification or quality documents. If there is no factory qualification or doubt about the quality, they must be inspected and meet the requirements before they can be used. Materials that have exceeded the factory's shelf life are not allowed to be used.

2. Key points of decoration construction

(1) According to GMP regulations, the design and installation of clean rooms should consider avoiding difficult to clean areas during use. During the purification decoration of this project, the gaps between the installation of doors and windows and the building, purification air conditioning, various pipelines, and lighting fixtures should be sealed.

(2) All accessories, partition walls, ceiling fixtures, and hanging parts can only be connected to the main structure and cannot be mixed with equipment and pipeline supports to prevent decoration materials from loosening and dust from falling off due to micro vibrations.

(3) The gaps between building decorations and doors and windows should be sealed on the front.

(4) According to the GMP certification inspection standards, interior decoration must meet the following requirements:

a、 Materials with good air tightness and minimal deformation under temperature and humidity changes should be selected.

b、 The surface of walls and ceilings should be smooth, even, dust-free, corrosion-resistant, impact resistant, easy to clean, and reduce unevenness. Make a rounded corner with a radius of 50mm at the junction of the wall and the ground. The wall color should be harmonious, elegant, and easy to identify pollutants.

c. Doors, windows, and interior walls should be straight, and the structure should fully consider the sealing of air and water vapor, making it difficult for pollutants to penetrate from the outside and preventing condensation due to temperature differences between indoors and outdoors. The gaps between interior doors, windows, and partitions in rooms of different cleanliness levels must be sealed.

(5) During construction, the amount of dust generated should be controlled, especially in concealed spaces such as ceilings and walls, which must be cleaned at all times.

(6) Dust laden decoration work cannot be carried out in rooms with installed filters.

(7) Pay attention to protecting the completed work surface, and do not cause dents, hidden cracks, and surface decoration pollution of the board due to impacts, knocks, trampling, and excessive water work.

3. Key points of air conditioning construction

(1) Ducts and components should be made of coated steel plates, and the inner surface of the ducts must be smooth and flat. Ducts must not be reinforced inside the ducts, and joint joints should be made using joint corner joints. The joints must be coated with sealant. Internal flanges should not be used for air duct connections. The air duct must be equipped with sealed cleaning holes, and there should be air volume measurement holes on the main pipe (as needed on the branch pipe). There should be pressure measuring holes before and after the filter. The bite joint of the exhaust duct in the explosion-proof area should be sealed with solder.

(2) After the installation of the air duct and before insulation, a leak check should be conducted. The air supply and return pipes should be checked for light leakage using the light leakage method, and the air leakage rate of the system air conditioner should not exceed 2%. Wipe the inner surface of the air conditioning system with materials that are not easily prone to fiber shedding.

(3) Before installing the filter, it is necessary to thoroughly clean and scrub the clean room and purification air conditioning system. After meeting the cleaning requirements, the purification air conditioning system should be continuously tested for more than 12 hours before cleaning and scrubbing the clean room again. The filter should be installed immediately.

(4) Before installing the filter, the packaging should be unpacked at the installation site for visual inspection, including whether the paper, filter sealant, frame, geometric dimensions, and smoothness meet the design requirements. Then, leak detection should be carried out. After passing the inspection and leak detection, installation should be carried out immediately. Unqualified products shall not be installed.

4. Key points for lighting construction and installation

(1) According to the GMP standards for pharmaceuticals, the clean room should provide sufficient lighting according to production requirements, and a review should be conducted before construction. The factory building should have emergency lighting facilities.

(2) The installation of lighting fixtures should be easy to clean.

(3) According to the GMP standards for pharmaceuticals, ultraviolet sterilization lamps are installed in workshops that require prevention of microbial growth and contamination.

(4) After the installation of indoor clean lighting fixtures, they should be cleaned in a timely manner.
