University/school laboratory is an important base for teaching, scientific research and technological development, and it plays a very important role in cultivating students' innovative consciousness, practical ability and problem-solving ability. The construction of Shanghai CEIDI Xidi Laboratory attaches great importance to laboratory safety construction, and helps the laboratory reduce construction and operating costs in terms of construction material selection, equipment purchase, layout planning, and hydropower design.

I.What are the classifications of university/school laboratory construction

The main categories of university/school laboratories are: Physics Laboratory, Chemical Laboratory, Biological Laboratory, and Psychological Laboratory. Among them, biosafety laboratories can be divided into P1 biosafety laboratories, P2 biosafety laboratories, P3 biosafety laboratories, and P4 biosafety laboratories according to their safety levels. Each university/school laboratory has specific experimental area planning requirements. For example, chemical experiments should include: volumetric analysis, routine analysis, sample pre-processing laboratories, etc.

II.The overall plan of university/school laboratory construction

1.University/school laboratory construction waterway: conventional water includes ordinary tap water, distilled water, and ultrapure water. Reasonable planning should be considered during construction, and the materials, namely water supply pipes and joints, should be selected according to specific experiments. Also consider the separation of water and electricity, the environment around the water pipe, the direction of the waterway, and so on. Sewage is more important, which is divided into polluted water and non-polluted water, such as acidic water, strong alkali water, heavy metal polluted water, etc. These waters need to be treated by environmental protection equipment before they can be discharged.

2.University/school laboratory construction circuit: There should be reasonable planning for the power consumption of weak current, lighting power and experimental equipment, especially the power consumption of instruments and equipment. Insufficient power will affect the service life of the instrument and bring some influence to the experiment. Stability factor. Should also control and reduce the fluctuation of the current, reduce or stabilize the change value of the harmonic, reduce or reduce the interference of the magnetic field, and so on.

3.University/school laboratory construction gas: high-purity gas pollution mainly occurs in the process of storage, transportation and measurement. During use, the airtightness of the gas cylinder and transmission system should be checked frequently. If a leak is found, it should be timely Take measures. In laboratories where conditions permit, a dedicated gas storage room should be set up to separate the oxidizing gas from the reducing gas, and separate the flammable gas from the non-combustible gas to prevent accidents.

4.University/school laboratory construction exhaust: This is a very important part of the laboratory. It is generally divided into local and global. It is perceived as local exhaust. For example, experiments that are prone to produce some harmful gases during operation need to be The exhaust is carried out in the equipment, that is, the fume hood or universal exhaust hood, atomic absorption hood. During the construction, attention should be paid to whether the wind speed of the exhaust is uniform.

5.University/school laboratory construction materials: According to different experimental properties, choose different materials to adapt to the laboratory environment. For example, corrosion depends on whether it is acidic, alkaline, or inorganic. Then select materials suitable for the degree of corrosion resistance to satisfy the laboratory.

6.University/school laboratory laboratory furniture: The teaching system laboratory is mainly set up for teaching purposes, and the experimental process is relatively simple and fixed. The requirements for laboratory furniture are mainly basic laboratory equipment, including commonly used laboratory benches, fume hoods, and utensils Cabinets, central laboratory benches, laboratory benches, etc.

III.Precautions for ventilation of college/school laboratory decoration design

For the university/school laboratory environment, conditions or conditions must be equipped with an air treatment system to avoid harm to the human body due to harmful gases generated in the experiment. Proper ventilation not only removes harmful odors in the laboratory, but also ensures the normal operation of the equipment. The number of air exchanges is currently advocated in general laboratories, in areas where steam and biochemical hazardous agents are used, air exchanges 12 times per hour. The air exchange in the microbiological inspection area reaches 16 times per hour.

1.All the instruments in the laboratory need power and the number of electrical sockets, the layout is reasonable and easy to use.

2.The electrical socket is three-hole or two-hole.

3.The voltage (220v or 380v) and power required by the instrument.

4.Full consideration should be given to the sockets required by the computer.

V,CEID college/school laboratory decoration design case

CEIDI, as an outstanding representative of Shanghai laboratory engineering EPC, has been deeply involved in the laboratory decoration design industry, creating a high-quality, safe and sustainable experimental environment for the majority of laboratory employees. Xidi's past university laboratory engineering projects are, for example,-laboratory transformation-the transformation project of the mechanical processing center of the School of Materials Science and Technology, Shanghai University of Science and Technology.

On July 22, 2019, the transformation project of the Machining Center of the School of Material Science and Technology of Shanghai University of Science and Technology, which was contracted by CEIDI, officially started. The School of Science and Technology of Shanghai University of Science and Technology uses the first-class scientific research facilities of the surrounding Zhangjiang Laboratory to carry out basic and interdisciplinary research. At present, there are three research directions: systems materials science, photon and condensed matter physics, and materials biology. Based on research needs, it is planned to build a precision machining workshop for machining precision parts processing and general operation teaching. The main purpose is to shorten the processing cycle of precision parts and improve the efficiency of scientific research.
