Design requirements of chemical laboratory
Release time:2018-08-02
The chemical treatment and analysis of the samples in the chemical laboratory often use some small electrical equipment and various chemical reagents, such as inadvertent operation and certain risk. In view of these characteristics, we should pay attention to the following requirements in the design of chemical analysis room.
(1) Building requirements laboratory building should be fireproof or built with non-combustible materials, partition and ceiling should also take into account the fire performance. It can be used on terrazzo floor, windows can be dustproof, and indoor lighting is better. The door should be opened outwards, and two exits should be set up in the large laboratory, so as to facilitate the evacuation of personnel when accidents happen.
(2) water supply and drainage must ensure the necessary water pressure, water quality and water quantity to meet the normal operation needs of the equipment. The total indoor valves should be located in easy to operate locations. Sewers should use acid and alkali corroded materials, and floor should have floor drain.
(3) Ventilation facilities often produce toxic or flammable gases in laboratory work, so laboratories should have good ventilation conditions
(4) gas supply and power supply conditional laboratory can be fitted with pipeline gas. The power supply in laboratory is divided into lighting and power consumption. A fluorescent lamp is best used for lighting. In the power supply of the equipment, the electric appliances operated by 24h, such as the refrigerator, are powered separately, the rest of the electrical equipment are controlled by the total switch, and the electric heating equipment such as the oven and the high temperature furnace should have special sockets, switches and fuses. He installed emergency lights in indoor and corridors to prepare for sudden power cuts at night.
(5) the experimental platform of the experimental platform is mainly composed of the platform, the scaffold and the temporary storage cabinet. For the convenience of operation, the drug shelf can be set up on the platform, and the water trough can be installed at both ends of the platform. The experimental table is generally 750mm wide and long. According to the size of the room, it can be 1500-3000mm and high can be 800-850mm. The table is usually made of corrosion resistant veneer plate, corrosion resistant core physicochemical plate, epoxy resin board or high temperature ceramic plate. Ideal mesa should be smooth, not easy to break, acid and alkali and solvent corrosion, heat resistant, not easy to shatter glassware, etc.
