Because the contamination degree of the ground is much higher than that of the wall and ceiling, a large number of dust particles are produced by the movement of medical staff on the floor and various equipment, so the ground decoration should be paid attention by designers. The following small edition of the operating room decoration will give you a summary of the requirements of the floor decoration of the operating room!
Ground decoration should be smooth, smooth, wear-resistant, corrosion-resistant (acid, alkali, medicine), easy to clean. Cast-in-situ terrazzo is often used in our country for its smooth, wear-resistant, dustproof, anti-static and easy to clean, but it should not be washed out with peracetic acid diluent, otherwise it will react with alkaline cement and lead to hemp surface. In addition, it is suggested that cement with strength grade 425 or above and stone size d=6-15mm should be used to prevent cracking, pebble dropping and sand blasting. Anti-static terrazzo floor is used in the clean operating room of Yueqing People's Hospital of Zhejiang Province designed by our school. Ceramic tile, mosaic (ceramic brocade brick) and other materials with obvious joints are also used in some low-level clean operating rooms, but generally not recommended.
Rubber, polyurethane paint and resin sheets can be used for high-grade floor decoration. For example, in many medical and surgical environments in Europe, America and Japan, elastic plastic sheets are used as floor materials. Its remarkable advantage is that there are fewer seams (usually hot-melt welding is used to connect the coils, and the welding rod is made of the same plastic material as the coils), which can avoid the accumulation of dirt and bacteria. In addition, it also has the advantages of pollution resistance, cleanliness, comfortable feet, various patterns, easy installation and replacement, which are incomparable with terrazzo. Advantage. Plastic coil floors were used in clean operating rooms of Shanghai Huashan Hospital and Shanghai Oriental Hospital.
In the vertical operating room, if the ground or ditch return air is used, the panel of the return air area should choose the block movable partition floor. Ground leakage should not be installed on the ground. Otherwise, high water-sealed ground leakage should be installed to prevent air permeability from polluting clean indoor air.
