The walls are clean and tidy. The walls and floors of the dispensing room should be clean and tidy, and it is not easy to stick stains. The color of the wall should be suitable for people's vision, with mechanical ventilation facilities (air conditioning, exhaust, electric fan) and air disinfection facilities (such as ultraviolet lamps). As a concentrated place of special vulnerable groups in society, the architectural features of hospitals are quite different from those of ordinary buildings, and the building decoration materials used are also different. The main performance is that the standard requirements of hospital wall decoration materials in cleanliness and hygiene are higher than those of ordinary buildings, such as dust prevention, fire prevention, weather resistance, cleaning difficulty and service life.
