The architectural decoration engineering of clean room mainly refers to the knot of floor and floor decoration engineering, plastering engineering, doors and windows engineering, ceiling engineering, partition engineering, paint engineering, grouting engineering, crevices and various pipelines, lighting fixtures, purifying air conditioning equipment and process equipment with buildings besides the main structure and external doors and windows. Sealing operation of joint gap.
The importance of building decoration in clean rooms is mainly manifested in the following two aspects:
(1) The impact on comprehensive performance: clean room requires no dust production, dust-free structure, tightly sealed and dustproof. Therefore, the decoration of the clean room will directly clean the effect.
(2) Influences on cost: Compared with general office buildings, clean rooms are high-cost buildings.

Material: epoxy composite aluminium plate, rust-proof aluminium plate, stainless steel plate, color steel plate. The base plate of the color steel plate is galvanized steel plate, the lining of the coating is alkyd resin, and the coating surface is thermal hardening acrylic resin or epoxy resin or polyester resin.
_The wall panels of the assembled clean room.
The general characteristics are: assembly cleanroom is a widely used form of cleanroom nowadays, especially suitable for reconstruction occasions. The characteristics of the wall panels vary from material to material. In addition to the characteristics of metal wallboard, double-filled wallboard also has the characteristics of heat insulation, suitable for air conditioning, especially for the occasion of constant temperature requirements. Double-filled panels have high strength.
Material: Wallboard is composed of surface material and core material. It should be selected according to the design object.
Fabrics include laminated wood, aluminium alloy plate, steel plate, color steel plate, etc.
Core materials are as follows:
A. rigid polyurethane foam: Wall foaming, excellent heat insulation. Halogenated organophosphorus compounds can be used as flame retardants. Because of different mixing methods, they can be classified as flammable, flame retardant and flame retardant.
B. Asbestos calcium carbonate: It is made of light calcium carbonate as main raw material, mixed with inorganic fibers and fire-resistant intensifiers to foam, and formed with a small amount of polyvinyl chloride resin as binder. It has good fire resistance and belongs to quasi-non-flammable profiles.
C. Polystyrene clip board: Through glue and pressure, the polystyrene board for thermal insulation is clamped between two steel plates, which will produce irritant gas when burning. The places with high fire protection requirements should not be used in large quantities.
D. clip rock wool board: clip rock wool between two steel plates, suitable for high fire protection requirements. But if the board needs to bear load, it needs to be lined with gypsum board, otherwise it is easy to deform.
E. Paper (aluminium) honeycomb board: The paper (aluminium) honeycomb is clamped between two steel plates. High strength, good fire resistance of aluminium honeycomb.
4. ceiling
(1) General requirements
The ceiling skeleton is light in weight, good in stiffness and convenient in construction.
The ceiling cover panel is less affected by human friction and more affected by vibration such as wind pipe on the ceiling, so it is more important to control the vibration shedding than the rigidity of the material surface.
(2) Species
The ceiling skeleton has:
Lightgage Steel Joist. It is characterized by light weight, less steel, cautious seam treatment, but difficult to master, can not be used as a temporary road and supporting heavy objects, troublesome maintenance.
Section steel keel. The utility model is characterized in that it can adapt to the arrangement of air supply outlets and lamp holes, but the steel consumption is large.
Aluminum alloy keel. It is characterized by the lightest self-weight and cautious seam handling, but it is difficult for the master to be used as a temporary road and a supporting weight, which causes troubles in overhaul.
Cover panels are:
Most of the materials used for wall surface can be used as ceiling cover panel material, in addition, color plastic plate is also a better cover panel material.

Material: Rubber rubber (such as NBR).
6. Special requirements
According to the Code for Construction and Acceptance of Clean Room, attention should be paid to the use of wood and gypsum boards.
(1) The moisture content of the wood used in the clean room should not exceed 16%, and it should not be used outside. Because of the large number of ventilation and low relative humidity in the clean room, such as the large use of wood, easy to crack, deformation, loosening, dust and so on, even if used, it should be used locally, and must do a good job of anti-corrosion and moisture-proof treatment.
(2) Water-proof gypsum board must be used when plasterboard is needed in general clean rooms, while for biological clean rooms, because they are often scrubbed with water and washed with disinfectant, even the water-proof gypsum board is damp and deformed, and cannot bear washing, so it is stipulated that plasterboard should not be used as cover material in biological clean rooms.
