Laboratory decoration due to long experimental time, many people and the experimental process of producing some harmful gases, causing air pollution, adverse to the human body. In order to prevent laboratory personnel from inhaling or swallowing toxic, pathogenic or toxic chemicals and organic gases, the laboratory should be well ventilated and air conditioned if necessary.
Ventilation equipment has ventilation cabinet, ventilation hood or local ventilation device. Need to pay attention to the organic solvent pretreatment and the use of electric furnace ventilation should be dealt with before the cabinet are arranged in different laboratories, local exhaust and exhaust hood must have sufficient power, otherwise difficult to meet the requirements in practical work.
2 humidity and temperature
Laboratory decoration requires proper temperature and humidity. Indoor microclimate, including temperature, humidity, and airflow speed, has an impact on laboratory personnel and instrumentation. Suitable summer temperature should be 18-28 degrees, winter is 16-20 degrees, and humidity is best between 30百分比-70百分比. In addition to the special laboratory, the temperature and humidity have little effect on most physical and chemical experiments, but the balance room and the precision instrument room should be controlled according to the needs of temperature and humidity.
It's important to keep the lab clean often. The outdoor dust in the atmosphere, through the ventilation process will enter the laboratory, the experiment of dust containing amount is too high, the air is not clean, not only affect the detection results, and the particles fall on the element surface equipment, may constitute an obstacle, and even cause a short circuit or other potential danger.
