What are the requirements for the production process of clean room purification engineering design?

When the production process has special requirements for temperature and humidity, it should be determined according to the process requirements. The temperature of personnel purification and living room should be 16-20 degrees in winter and 26-30 degrees in summer. (1) The clean environment serves the production process, and the design of the clean room must meet the environmental requirements of the production process, which is a matter of course. Therefore, when designing a clean room, the production process's requirements for environmental parameters should be realistic. The area, layer height, temperature, humidity, cleanliness, etc. should be high or high, and low or low, not higher is better. On the premise of not affecting the normal operation of the production process, the parameter requirements should be reduced as much as possible, the purification area should be controlled, the scope of the high purification level clean area should be reduced, and the area of ​​the 100-level and higher one-way flow clean area should be strictly controlled. (2) When zoning the production process plane, arrange the clean rooms of the same level as much as possible, set the processes with high cleanliness requirements on the windward side, and place the processes that produce dust, toxic, harmful, flammable and explosive waste gas. Equipment and containers should be placed outside the clean area as much as possible. If they must be placed in the clean area, airtight measures should be taken as much as possible to reduce the emission of dust and exhaust gas. Purification decorative wall and ceiling installation According to the design requirements, the glass-magnesium sandwich color steel plate partition wall and the glass-magnesium sandwich color steel plate ceiling are used. In order to ensure that the room is not easy to accumulate dust and is easy to clean, the corners of the wall are made of R50 arc inner corners, arc outer corners, arc strips and other aluminum alloy high-quality materials, which must be selected strictly according to the design requirements, reasonable settings, and careful installation (as shown in the picture) Technological process: according to the floor plan, the pharmaceutical cleanroom wall is arranged on the ground and the line is positioned on the ground - with the ground manger - put in the U-shaped ground manger and fix the self-tapping Rose on the ground with shooting nails - install the wall decoration and splicing the wall Decorative material - install expansion screws on the floor according to the design requirements - install hanging rods - install hooks on the ceiling decorative material - install hooks on the ceiling decorative material - fix the U-shaped ground manger with rivets on the ceiling decorative material - install the ceiling Decorative materials and splicing ceilings - door frame installation - opening of pipe holes and air supply holes and door installation - installation of arc inner corners, arc outer corners and arc strips - cleaning joints - smearing glass glue at the joints - cleaning the inner wall of the room And the main points of ceiling operation: ① Determine the position of the partition wall according to the design requirements, the line should be straight, the U-shaped ground manger should be fixed by nails or self-tapping, the spacing should be uniform, and it should be fixed in a 'zigzag' shape. ② The wall and ceiling decoration materials should be lifted and handled gently. It is not allowed to bump, collide, scratch or scratch the surface of the color steel plate. It is not allowed to have uneven wall and ceiling decoration materials, uneven splicing and loose joints, and aluminum alloy at the splicing. The profiles are not allowed to have bumps and scribe marks. The decorative steel plate and the sandwich material are firmly and tightly attached, and are not allowed to be broken apart. ③ The splicing position of wall and ceiling decoration materials should be reasonable, and the overall strength should be good after connection. 2. Self-leveling construction technical scheme 3.1 This self-leveling adopts a primer, a middle layer, and a self-leveling flat paint, and the imported epoxy resin self-leveling floor should be used. 3.2 Construction procedures: (1), remove the sundries in the purification area. (2) Use an industrial vacuum cleaner to vacuum the ground to remove the floating dust on the surface. (3) Use a high temperature flame spray gun and solvent cleaning to remove the oil stains on the surface. (4) Use a polishing machine to roughen the surface, especially the polishing of glass strips. (5), vacuum, epoxy resin self-leveling ground construction. (6) The construction of the base oil, after curing, transfer to the next process. (7), the construction of the intermediate layer, after curing, transfer to the next process. (8) For the construction of the self-flowing plane layer, pour the prepared solvent-free topcoat material onto the ground, smooth it with a spatula, and then roll the air with a barbed circulation cylinder. 3.3 Acceptance criteria of the project After the construction is completed, the acceptance shall be carried out according to the following standards: (1) The construction surface is seamless and free of ash; (2) The product does not crack, fall off, or peel, and has good adhesion to the base layer. ; (3), the surface of the product has no bad phenomena such as pinholes, holes, and vortices; (4), the color is uniform, and the gloss is bright (5), the surface of the product is hardened uniformly; (6), the self-leveling floor meets the requirements listed in the product manual standard. 3. Arc and fillet treatment Ground Arc treatment The ground is treated with aluminum alloy double arc strips, which can not only ensure the arc transition of the ground color steel plate, but also fix the color steel plate to ensure that the ground cushion is flat and the walls are not on both sides. Leakage water, in this way, can also ensure that it will not rust. The arc between the wall and the ceiling handles the arc transition between the wall and the ceiling. In order to facilitate installation, the arc transition between the plate and the wall adopts the sky riveting positioning, and the arc strips and arcs are inserted on both sides of the wall. horn.
