What are the requirements for the construction of physics laboratory?

The general idea of physics laboratory construction should be scientific, innovative, open and advanced. Providing a good environment for the installation and operation of laboratory equipment, and avoiding the equipment running in harsh environment, not only helps to improve the trouble-free running time of equipment system, but also reduces the occurrence of accidents. A good environment can also extend the service life of equipment. So, what aspects should be considered in the construction of physics laboratory?

First, tables and chairs.

According to the size and environment of the classroom, personalized design can be adopted, such as rectangular, square, oval and L-shaped design methods; The material selection of tables and chairs should be solid, green and easy to clean; The choice of desktop materials is wear-resistant, heat-resistant and corrosion-resistant; The colors of tables and chairs are reasonable, creating a quiet, pleasant and creative experimental atmosphere.

Second, the ground.

It is recommended to use anti-static floor (reconstruction) or plastic floor (new construction). To make the ground fresh, tidy and beautiful, it is recommended to use durable, cost-effective and convenient cleaning materials.

Third, the wall

The setting of the wall should make full use of space and make it a cultural wall, so that it contains cultural elements of modern information technology and experiments. It is infectious and enhances students' awareness of the combination of information technology and routine experiments. The wall is lined with the history of experimental development, picture introduction of various equipment, mainstream information, experimental program chart and so on.

Fourth, lighting.

Natural light and auxiliary lighting are used in the laboratory, and the illuminance uniformity of the operating table should not be less than 0.7, and there is no visible glare indoors, so it has good illuminance. Windows should be fitted with curtains to avoid direct sunlight on the equipment.

V. Air conditioning and ventilation equipment

1. Indoor temperature

According to different equipment, the usual requirement is 5℃-40℃. In general, network equipment should be guaranteed to run at room temperature of 18℃-22℃.

2. Indoor humidity

Depending on the equipment, it is generally 20%-80% without condensation.

3. The laboratory needs to install necessary air conditioning equipment and ventilation equipment. Ensure that the above temperature and humidity conditions are met. The air in the laboratory should also be kept clean, people should change slippers when entering and leaving, and air conditioning equipment and ventilation equipment should have air purification function.

Security measures of intransitive verbs

Equipped with fire prevention, moisture-proof and anti-theft facilities. Power load space should be reserved, strong and weak current lines should be set according to the specifications, air conditioning lines should be laid, leakage overload protectors and reliable grounding protection should be installed. At least one water supply and drainage facility. It is suggested to install smoke alarm to detect fire and ensure safety.

Seven, the total power control

The laboratory student experiment table should supply power to the table, and the teacher demonstration table is equipped with a master power control device to centrally control the student experiment power supply and electric shock protector. The laboratory should be equipped with shading curtains; The power socket should be fixed (or embedded) inside the test bench. The laboratory should be equipped with several network information ports, and the laboratory should be equipped with digital multimedia projection equipment (computer, digital projector, video booth, interactive whiteboard and sound system).

The laboratory is the cradle of science. To do experiments well, we must do a good job in laboratory construction. Therefore, the construction of physics laboratory needs to be carried out in strict accordance with the requirements of all aspects.
