Clean Room Construction Process

Structural Decoration Construction Process And Introduction

The cleanroom panel is usually sandwich panels. According to the production process of sandwich panels, it is divided into manual panels and machine-made panels, and its contents are divided into rock wool sandwich panels, aluminum honeycomb sandwich panels, phenolic sandwich panels, glass magnesium sandwich panels, foam sandwich panels, etc., the surface spraying of sandwich panels can be single-sided or double-sided according to specific use requirements, and the properties of the sprayed materials include anti-static sandwich panels, anti-salt sandwich panels, and anti-corrosion sandwich panels. The thickness of the panel is conventionally divided into 50mm. 100mm. For example, single-sided antistatic handmade rock wool sandwich panel, d=0.5mm, 50*4100*1180.

Cleanroom Structural Decorative Sandwich Panels

Structural decoration construction process:

1. On-site spot investigation and positioning
2. Installation of anchor groove aluminum and ceiling screw
3. Panel installation
4. Ceiling installation
5. Doors and windows installation
6. Return air column installation
7. Return air louver installation
8. The overall finishing of the installation of the edging and landscaping structure

Clean Room Construction Process-The main structural plate for the decoration of the clean room construction envelope is a color steel plate.

Introduction to the content of clean room structure decoration

Civil And Steel Structures

This content is relatively small in plant decoration and cleanroom construction. It is related to the equipment foundation of public equipment and process room, and the equipment entry space. Before the equipment arrives at the site, according to the construction requirements of the drawings, the equipment foundation needs to be constructed in advance, concrete or steel structure materials can be an equipment platform. According to the situation on-site, there may also be limited access space for equipment. It is necessary to widen the wall, make temporary equipment entrance openings, and work related to the civil partition of the public equipment room. This requires part of the civil construction and steel structure construction in the early stage. Civil construction is mainly in the doorway wall and foundation, and the civil construction of the clean room system engineering mainly focuses on the civil concrete foundation and the steel structure foundation platform. On-site construction needs to plan the size of the relevant foundation according to the size of the equipment, and reserve part of the construction installation surface. The steel structure platform should pay attention to the anti-rust painting treatment, and the foundation of the civil concrete equipment lies in the spacing between the rebar specifications and the rebars. If necessary, the photo process of concealed acceptance, the document should be kept. (Marya doesn’t provide civil construction)

Ground Decoration

The main types of floor decoration are PVC floor, epoxy floor, etc:

1. PVC floor:
In the clean room construction, the PVC floor is generally completed before the equipment enters the site, creating a good environment for equipment installation and debugging, and finishing touches are required after the positioning and debugging are completed later.

The edge processing ensures the beauty and integrity of the ground engineering. Common after-sales maintenance problems are empty drums and damage.

Epoxy floor construction can be divided into three stages: early stage, middle stage, and later stage:

1. Early stage. Before the construction materials and personnel and equipment enter the site on a large scale, when the construction surface is perfect, the civil ground is ground and leveled, and the primer construction is carried out to create a clean room construction surface. Generally, to ensure the relative cleanliness of the main material of the clean room and the construction process, the primer construction can effectively reduce the dust generated by the concrete layer of the civil ground floor during the construction process.

2. Mid-stage. The middle coat and top coat shall be applied before the equipment enters the site. According to the thickness and requirements of each epoxy floor in the construction process, refer to the construction technical requirements and process of the on-site ground construction team, and set aside time for construction and drying, and solidification. (If the equipment enters the site without relevant ground requirements, it can also be delayed. If the ground is done early, there will be a risk of scratches and damage during the subsequent construction process.) After the indoor support and hanger pipes are completed, other construction majors will free up the construction work surface for the ground construction majors. If the construction period is tight, the remaining main works of each major are relatively large, and the construction can also be divided into areas and sections.

3. In the later stage, the floor decoration of the clean room is finished as a whole, and there may be scratches on the ground during the equipment or construction process, the transfer of the equipment position, equipment position transfer, and ground repair after the change, ground reserved equipment or blocking of process interface. In principle, after the epoxy topcoat is finished, dry, and solidified, no large construction equipment such as forklifts, lift trucks, etc. can enter. If it is necessary to enter the venue, the tires need to be cleaned and wrapped in a flexible package to prevent damage to the surface coating. Workers emphasize the awareness of finished product protection in subsequent construction.

Envelope Decoration

The main structural plate of the cleanroom construction enclosure decoration is a sandwich panel, and the splicing method is a conventionally male-female connection or full-female middle-word aluminum connection.

The sandwich material is subject to the design scheme and construction drawings.
The window structure needs to be ordered in advance and integrated with the structural plate.

The door can be reserved for relevant holes for later installation or integrated installation. To prevent subsequent construction damage, holes are often reserved for delayed installation.

The purpose of common clean room enclosure partition structure decoration is mainly to divide Different functional areas to create a clean area. If the wall panel has fire resistance, it can also be used as a fire partition depending on the fire protection regulations.

In the process of construction, special attention should be paid to the protection of finished products. It is often seen that large equipment such as lift trucks and forklifts damaged the panel due to improper operation. There is no repair on site, and the whole panel may only be replaced, which consumes labor and materials and damages the overall aesthetics.

During the construction of the cleanroom, there are many intersections with the fire emergency power supply, sound and light alarms, and fire shutters.

The fire-related end devices will open holes in the sandwich panel, and the exposure of rock wool and other contents will affect the cleanliness of the cleanroom.

Ceiling Structure

The construction of the cleanroom ceiling is generally completed before the entry of the workshop equipment, and the part of the cleanroom ceiling constitutes a complete clean workshop. Multi-purpose sandwich ceiling panel or T-shaped keel ceiling always be used.
The sandwich ceiling panel is divided into two types: surface-mounted and concealed. The basis for the division is whether the hanging beam can be seen at the bottom of the ceiling. The sandwich ceiling panel is mostly used for the cleanroom system of supply and return air + high-efficiency air supply outlet, and the T-shaped keel is mostly used for the new wind FFU cleanroom purification system.

beautification structure decoration

After the main body of the clean room structure is completed, the arc mounting is carried out, and the exposed pipes in the workshop with relevant engineering quantities quotations are wrapped and beautified with color steel plates (mainly risers), and the valve inspection port or operation port in the wall is reserved for packaging. , fire-related fire hydrants, etc. This construction content reflects the overall clean room aesthetics and quality content, and reflects the cleanroom construction quality.
