Instrument laboratory design and decoration requirements and specifications

Instrumental analysis laboratories generally require more indoors than chemical laboratories. Instrumental analysis laboratories generally have air conditioning requirements, such as constant temperature and humidity, air purification, airflow, and exhaust. Moisture protection is required in humid climates. For early laboratories, several infrared lamps, small dehumidifiers, window air conditioners, and small freestanding air conditioners are used. Modern laboratories conditionally use central air conditioning systems. For instruments and equipment with high anti-vibration requirements, in addition to the consideration of the location of the laboratory, it is necessary to consider the setting of independent equipment anti-vibration foundation and vibration isolation measures. Instrumental analysis laboratories generally require both AC and DC power supplies, as well as single-phase and three-phase power outlets, and often have voltage regulation requirements. Some also have anti-electromagnetic interference requirements, requiring grounding and electromagnetic shielding. Some need cooling water and various gas supplies, including vacuum and compressed air, protective gas and carrier gas. The building decoration standards of the instrumental analysis laboratory are usually considered to be higher: wall paint or paint wall skirt; ground floor, terrazzo floor, plastic floor and marble floor; laboratory test bench: sample processing room The worktable can refer to the chemical test bench; if the workbench for placing the instrument needs to be stable, the terrazzo countertop of the reinforced concrete structure can be used. Similarly, the laboratory requires dust protection and corrosion protection, and should be given sufficient attention and properly resolved.

1. Requirements for instrumental analysis laboratory:

Instrumental analysis experiments mainly include a variety of large-scale precision analytical instruments, as well as ordinary small analyzers. Most of these analysis rooms are composed of several small rooms. The size and number of rooms vary from instrument to instrument; even if they are different types of instruments, their requirements are often different, and sometimes there will be big differences.

2. The composition of the instrument analysis laboratory:

The instrumental analysis laboratory consists of an analytical instrument room, a sample processing room, a dark room, a research room, a dressing room, and a machine room.

3. The layout of the instrument analysis laboratory:

The instrumental analysis laboratory has anti-vibration, dust-proof and relatively constant room temperature requirements and certain humidity requirements. The specific design should meet the requirements of the instrument product specification.

Instrumental analysis laboratories can usually be arranged along the outer wall like the basic laboratory, or they can be concentrated in a certain area, which is conducive to the connection between the various research laboratories and the basic laboratory, and can be considered in terms of air conditioning, protection, etc. Measures. For a certain scientific research project, for the sake of practical research, the instrumental analysis laboratory can also be considered to be distributed according to scientific research projects, so that the same analytical instrument room has multiple groups in one building. In addition, in an experimental building with a centralized air conditioning system, it is advantageous to have no special auxiliary laboratories along the outer wall. Below are several design examples for the instrumental analysis laboratory.

(1) Large-scale spectral laboratory layout

(2) X-ray diffraction analysis room layout

(3) Electrochemical analysis room layout

(4) Electron microscope laboratory layout

(5) Optical inspection room

(6) Mechanical Energy Measurement Laboratory

(7) Thermal performance measurement laboratory

(8) X-ray fluorescence spectroscopy laboratory

(9) ICP spectrometer layout

4. Interior decoration of the instrument analysis room:

4.1 floor

Small and ordinary instrument analysis room can meet the needs with a fixed floor, but for large precision instrument analysis laboratories, such as X-ray fluorescence spectrum chamber, mass spectrometry chamber, ion-controlled needle chamber and other laboratories, because of the large number of cables and complicated pipelines, it is necessary to adopt Overhead floor. When the air supply method of the lower return air is adopted, the space under the overhead floor can also be utilized as the air supply static pressure box. The general floor structure has the following types.

(1) Shield type: When the number of cable lines is small, it can be bundled and bundled, and when it is used for clear wire wiring, in order to prevent the wire from being damaged, a shield can be added to the wire to protect the height of the cover from obstructing the cabinet. The door leaf switch is suitable.

(2) Gutter type: the ditch is made under the floor through which the cable passes. The ditch is generally 250mm wide and 150mm deep. The ditch cover is made into a movable cover after being cut into pieces, and a few aluminum flat handles are attached. Open.

(3) Raised floor: Also known as the assembled floor, it consists of panel blocks of various specifications and materials, adjustable supports, beams, cushions, etc. The movable floor overhead is provided on the floor of the instrument room for installation equipment, laying space for various pipelines, cables and air conditioner static pressure boxes.

The raised floor should have excellent mechanical properties, light weight, high strength, smooth surface, stable size, flexible interchangeability, good decorative and texture, and can meet the requirements of moisture, flame retardant and anti-corrosion. The raised floor is divided into anti-static type and non-anti-static type.

Ø Mobile floor use requirements and features:

1 It can be assembled easily and quickly regardless of the shape and size of the room.

2 Free access to electrical cables and ducts for easy laying and maintenance.

3 bearing capacity ≥ 800kg / m2.

4 meet the fire protection requirements.

5 can discharge static electricity to the ground and reflect electromagnetic radiation.

The 6 floor detachable panels are interchangeable and have a high production precision to achieve the required sealing when using the underfloor space as an air conditioning static pressure box.

7 The board surface is noise-free and wear-resistant. It can be scrubbed or dry (with a vacuum cleaner).

8 Level the unevenness of the ground with adjustable support.

4.2 doors and windows

1 Room doors with air conditioning and cleanliness requirements should be sealed or insulated with one-way spring doors or automatic door closers, and opened indoors. For doors with strong noise and doors to the computer room, a soundproof door should be used.

2 When there is air conditioning and clean room requirements, it should be double sealed window. When aluminum alloy windows and plastic steel windows are used, a single-layer sealing window of insulating glass can be used to ensure the thermal performance of the surrounding wall structure.

3 The outdoor window of the instrument should be facing north. If the conditions are restricted, when the window is opened to the east, south and west, measures such as sunshade and curtains should be taken to prevent direct sunlight and glare.

4 The doors of each room should ensure the convenience of personnel and equipment.

4.3 Interior decoration requirements:

1 The precision instrument analysis room and the main auxiliary room interior decoration should choose easy-to-clean, dust-free and hard-to-burn materials. The surface of the wall and ceiling should be flat, reduce the dust surface, and have the effect of heat preservation, sound insulation and sound absorption. The floor material should be smooth, wear-resistant, easy to dust, and take anti-static measures as needed.

2 The general auxiliary room interior decoration can be designed according to the relevant standards according to the use of the room.

3 Indoor various pipelines should be darkly applied, and technical shafts should be set when the pipelines penetrate the floor.

4 The air outlets, lamps, fire detectors and fire extinguisher nozzles installed on the indoor ceiling should be arranged in coordination with each other on the wall to make them neat and beautiful.

5 partition wall setting, in addition to the fixed partition wall, it is best to use flexible partition to adapt to the needs of instrument renewal and expansion.

6 indoor color should be light and elegant, with a fresh and quiet effect, it is not appropriate to use a large area of ​​strong color. A matt or matt finish should be used in the furniture and in the room.
