As people continue to pursue quality life, the production environment of products in all walks of life is also constantly improving, and clean rooms are also being used more and more. A clean room is an engineering space that maintains very low concentrations of airborne particles. It is well insulated, contamination well controlled, and aggressively cleaned. It must be mentioned here that the important role in the clean room is polytetrafluoroethylene filter paper.
Clean rooms maintain particle-free air through the use of HEPA or ULPA filters that use laminar or turbulent airflow principles. Laminar or unidirectional airflow systems direct filtered air in a constant downward or horizontal direction to filters located on the wall near the cleanroom floor or through an elevated perforated floor to be recirculated. Laminar airflow systems are typically used in 80% of the cleanroom ceiling to maintain constant air handling. Stainless steel or other non-shedding materials are used to construct laminar airflow filters and hoods to prevent unwanted particles from entering the air. Turbulent or non-unidirectional airflow uses laminar flow hoods and non-specific velocity filters to keep the air in the clean room in constant motion, although not all in the same direction. The rough air attempts to capture particles that may be present in the air and push them toward the floor, where they enter the filter and exit the cleanroom environment.
Currently, polytetrafluoroethylene filter paper made of self-developed ptfe microporous film and imported non-woven fabric thermally composited is clean The core material of the chamber filter has a reliable grade of H13-U16 filtration efficiency, meets the filtration requirements of HEPA and ULPA, and has low wind resistance, low energy consumption, wide chemical applicability, and good retention effect. Polytetrafluoroethylene filter paperWidely used in photovoltaic, semiconductor, electronic flat panel and other industries. Interested parties are welcome to enter the store for consultation.
