Specifically talk about the construction points and requirements of the clean workshop
The installation of the enclosure structure of the clean pharmaceutical cleanroom is completed by the main supervisor in the interlayer, and then the indoor floor wall and space are cleaned, and the construction is carried out after there is no dust accumulation, and the parts and the site are cleaned by personnel during the construction process.
1. Before construction, be familiar with the secondary design drawings, complete the site survey, and be aware of the errors of the original civil engineering room. The fixing of the connecting parts with the main structure and the ground, such as hanging, shall be carried out in strict accordance with the requirements of the secondary design drawings.
2. According to the specific situation of the site and the composition of the purification system, the construction is carried out step by step and planned, so that the construction of various types of work can be combined to speed up the construction progress.
3. The ceiling should be arched according to the width of the room, so that the ceiling will remain flat during the use process after being loaded. The surrounding area of u200bu200bthe ceiling should be closely connected with the wall, and the protective film on the surface of the board should not be torn off during the installation process. Do not strike and step on the pedal surface.
4. The material that needs to be pasted on the surface layer, the surface and groove of the sealant are embedded to avoid falling off and accumulating dust, and it needs to be cleaned strictly to remove impurities and oil to ensure that the adhesive is dense and firm.
5. The installation gap of the enclosure structure needs to be sealed with silica gel, and the embedded sealant should be straight, smooth, and should not have any interruptions, such as burrs. The ambient temperature for gluing should be above 0 degrees Celsius.
6. In the case of frequent opening and closing of the door, except for some external doors, in order to avoid the transportation of heavy equipment, etc., the airtight strip is set on the door. Under normal circumstances, in order to prevent the sealing strip from being hand-moulded, stepped on or hit as much as possible, it will be affected by pedestrians and transportation. Small-section elastic sealing strips with a length of several millimeters are laid in the hidden grooves of the gatehouse, and then borrowed The door leaf is closed tightly. The sealing strip should be laid continuously along the perimeter of the movable gap so as to form a sealing line with a closed tooth shape after the door is closed. If the airtight strips are set at the door sill and the door leaf respectively, it is necessary to pay attention to the good connection between the two, and minimize the interruption gap of the airtight strip at the door seam.
7. Pipeline passing: When the pipeline passes through the enclosure structure, it needs to have a good fixed structure, and it cannot be shaken and displaced during use, so as to ensure the effect of the sealing measures. It is necessary to combine both installation positioning and sealing treatment. Therefore, a positioning skeleton is attached to the periphery of each hole opened on the wall plate. If the large-sized air duct is strong, it should avoid front and rear, left and right, and up and down movement. Pad glue or sponge pad in the gap between the duct wall and the wall plate and then use sealant.
8. The floor of the clean workshop is terrazzo floor (before self-leveling), and an integrated manger is used between the ground and the wall to ensure that the siding is not distorted horizontally. Glue needs to be injected at the junction of the manger and the ground. In order to avoid the penetration of water or other liquids from the partition wall position.
9. Before purification and decoration, the indoor space needs to be cleaned to no dust. The color steel plate and accessories should be stored in a clean environment and placed flat on the moisture-proof film to avoid deformation. Siding and accessories should be unpacked in a clean environment. Substandard or damaged products must not be installed.
10. The siding partition wall should be installed flat, and the board seams should be vertical and tight. The fixing and hanging parts of the suspended ceiling can only be connected with the main structure, and cannot be mixed with equipment and pipeline supports. The surface of the siding and ceiling should be smooth, smooth, free from ash, dust-free, corrosion-resistant, impact-resistant, and easy to clean.
11. The corners between the floor and the wall, the wall and the wall, and the wall and the ceiling in the clean room are made of Ru003d50mm aluminum alloy rounded corners and sealed with silicone. R rounded installation needs to be straight and the joints are tight.
12. Sealed windows, clean doors and partition gaps need to be sealed with silicone.
