purifyCleanliness level requirements for workshop：

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.

Dust-freeTo achieve good cleaning results in the workshop, it is not only necessary to focus on adopting reasonable air conditioning purification measures, but also to require corresponding measures to be taken by 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 clean rooms 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.

1Air supply 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.

2Airflow 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.

3Supply 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.

4Static pressure difference:

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

purifyInstallation and use of workshop:

clean roomMeasures to ensure cleanliness and compliance with standards：

1Purpose:

(1)To ensure the quality of the cleanroom project, the construction, acceptance, and testing of the cleanroom must be carried out in accordance with the "Construction Organization Design" and "Good Manufacturing Practice for Drugs"(GMP)98》And the 'Code for Construction and Acceptance of Cleanrooms'.

(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.

2Key points of decoration construction

（1）According toGMPAccording to regulatory requirements, clean rooms should be designed and installed to avoid areas that are difficult to clean during use. When carrying out purification decoration in 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 toGMPCertification inspection standards, indoor 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 surfaces of walls and ceilings should be smooth, even, dust-free, corrosion-resistant, and impact resistant

Easy to clean, reducing unevenness. Make the junction of the wall and the ground with a radius equal to50mmThe rounded corners. wall

The complexion 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 to prevent pollution particles

The child is not easily infiltrated from the outside, preventing condensation due to temperature differences between indoors and outdoors. Indoor cleanliness varies

The gaps between the interior doors, windows, and partitions of the rooms 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.

3Key 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(There should be pressure measuring holes before and after the filter on the branch pipe as needed. 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 exceed2%Wipe the inner surface of the air conditioning system with materials that are not easily prone to fiber shedding.

（3）Before installing the filter, the clean room and purification air conditioning system must be thoroughly cleaned and scrubbed. After meeting the cleaning requirements, the purification air conditioning system can be started for continuous trial operation12After more than an hour, clean and scrub the clean room again, and immediately install the filter.

（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.

4Key points for lighting construction and installation

（1）According to the medicationGMPStandardize that the clean room should provide sufficient lighting according to production requirements, and conduct a review 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 medicationGMPStandardize the installation of ultraviolet sterilization lamps 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.How much is the decoration cost per square meter for Pingdingshan purification workshop
