In the entire construction engineering system, clean room engineering can be regarded as a relatively obscure sub-division project. It usually appears in hospitals, pharmaceutical factories, and industrial dust-free workshops. Clean room engineering is a complete system, which includes building structure, building decoration, wind system, gas system, water system, chemical material supply system, power distribution system, automatic control system, equipment installation, fire protection system, and shielding facilities. Big items. Next, follow the HEPA high-efficiency filter paper manufacturer to learn more.
In hospitals, the operating room is often in need of a clean environment, because if the patient becomes infected during the operation, There will be serious consequences. There are three main ways of surgical infection: direct contact infection, patient’s own infection, and infection caused by airborne germs falling into the wound. It is understood that 25% of wound infections in clean operating rooms come from pollutants in the air.
Under normal circumstances, the air must pass through three levels of filtration before being transported to the clean operating room. This is mainly to control microorganisms in the air and Non-microbial particles. The primary efficiency filters out particles and foreign matter above 10 microns, the medium efficiency filters out floating particles within the range of 1-10 microns, and the high efficiency filters out submicron particles below 1 micron. These are particles that cannot be filtered out by the primary efficiency and the medium efficiency. This is also It is a very critical part of the purification air supply system in the operating room. High-efficiency filtration (HEPA high-efficiency filter paper) can filter out particles and tiny bacteria.
From the air supply side to the return side, small bacteria need to be filtered and removed, but the airflow will not change when flowing through the cross section. Under the influence of the air supply static pressure box and the high-efficiency filter to balance the pressure and air flow, the flow rate on the entire clean operating room is uniform and no vortex will be generated. In short, the one-way flow clean room principle in the operating room purification project relies on the push-out effect to discharge the dirty indoor air to the outdoors, so that the indoor air can be purified.
As a high-efficiency separation filter material design solution provider, we are committed to protecting personnel and processes by developing and manufacturing high-quality PTFE air filter membranes and composite materials. and system. And for clean room applications, a clean room high-efficiency air filter material – HEPA high-efficiency filter paper has been specially developed, which can be used as the core filter material of clean room high-efficiency air filters. HEPA high-efficiency filter paper It has a reliable filtration level of H13-U16, low wind resistance and low energy consumption, and is widely used in semiconductor, electronics, flat panel display, photovoltaic and other industries.
