Indoor installation in clean workshop
The air tightness of the enclosure structure of the clean workshop is an important factor to ensure the indoor cleanliness parameters. The gaps generated by the deformation of the material when the temperature and humidity change cause air leakage and dust generation, so the air tightness should be selected. And the material with small deformation under the action of temperature and humidity changes; the inner surface of the clean workshop should be as smooth as possible to reduce the uneven surface, reduce the possibility of dust accumulation, and facilitate cleaning and disinfection; all structural gaps should be tightly sealed with neutral sealant Blocking, the joints of the wall panels and the top panels should not be in the form of cover seams. The junction between the wall and the ground should be arc-shaped to facilitate cleaning; the skirting should not protrude from the wall, in order to reduce dust accumulation and facilitate cleaning. Clean; at present, the form of skirting is mostly used, such as roll up and paste on the wall board, additional metal arc bead, epoxy mortar or coating, etc.
The ground should be flat, smooth, wear-resistant, easy to clean, and free of cracks. At the same time, it should also meet the requirements of different production processes, such as the production of solid preparations, the material transportation volume is large, the requirements for the ground's wear resistance are high, and the sterile For drug production, the ground is required to have better properties of easy cleaning and disinfection resistance. The ground cushion should be equipped with a moisture-proof layer to prevent groundwater from infiltrating the ground through capillaries, resulting in flooding, bulging and other phenomena, damaging the integrity and durability of the surface layer. sex. The temperature difference may cause condensation on the inner surface, which will bring pollution risks to clean production. The outer windows should be fixed with insulating glass windows, and the operation rooms with higher cleanliness levels should not be equipped with outer windows. The door of the production area should be equipped with a door closer, so that the door can be closed in time to ensure the pressure difference. Generally, the high cleanliness room is relatively positive pressure compared with the low cleanliness room. Opening the door to the high cleanliness room can ensure its airtightness; To avoid the accumulation of indoor dust in the ground gap, and at the same time to facilitate the entry and exit of production and transportation tools, the door of the clean workshop should not be set with a threshold. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and sterile workshops.
In order to ensure that the high-efficiency air filter is not polluted during installation, there are certain requirements for the installation environment. When the high-efficiency air filter needs to be replaced in the technical interlayer, the technical interlayer should be brushed with paint in addition to requiring a smooth surface; It can withstand the load requirements of maintenance personnel and maintenance tools. An inspection aisle should be set up in the technical mezzanine, which should be convenient for maintenance personnel to move in the technical mezzanine, so as to avoid gaps in the ceiling due to repeated trampling and deformation, which will affect its air tightness. The point should be set separately from the hanging point of the suspended ceiling; when the height of the technical interlayer is greater than 3m, the horizontal steel trellis layer should be set at an appropriate elevation, which should bear the load of the suspended top layer and shorten the height of the suspension rod to ensure the integrity of the suspended ceiling.
