The type of air filter has a lot of filtering characteristics, field of use are not the same, what filters are PTFE efficient? His characteristics and application areas in which? First, PTFE is polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), a tetrafluoroethylene monomer as the polymerization of the polymer. White, waxy, translucent, heat resistance, good cold resistance, long-term use -180 ~ 260ºC. This material has acid alkali, resistance characteristics of various organic solvents, almost insoluble in all solvents. Also, polytetrafluoroethylene having high temperature characteristics, its low coefficient of friction. Efficient and PTFE / ULPA filter is a high efficiency particulate air filter made of PTFE film. He has a high filtration efficiency, low pressure loss, high dust holding capacity, tough paper, good sealing, compact structure, easy installation, resistance
A ventilation system Rated air volume: In the rated condition, the air volume flow inhaled or discharged within the unit time. Rated wind pressure: When the rated air volume, the device has full pressure. Export wind speed: The average wind speed of the device at the exit. Device resistance: Fully pressure loss diffuser when air flowing over equipment: The air outlet of the blown or smooth diffusion is formed by the fixed blade and the adjustable blade. Adjustable spindle: the air outlet adjustable in the circulation cross section, the direction of the guide. Air curtain (spout machine): consists of a static pressure box of a fan, a flat air flow is formed by sufficient wind speed to isolate the air convection air supply system. Change fans: Device excluding indoor air or delivery in indoor air. two

The installation of the high-efficiency air filter should pay attention to the installation seal of the high-efficiency filter, the sealing method has contact filler seals, and the liquid trough knife seal and negative pressure leak seal. Related Standards: \"Clean Surgery and Medical Design and Installation\" GB / T1355 \"High-efficiency Air Filter\" GB / T6165 \"High-efficiency Air Filter Performance Test Method, Transmission and Resistance\" GB50073 \"Clean Factory Design Specification\" GB50333 \" Hospital Clean Surgery Building Technical Specification \"1. High-efficiency air filter product characteristics and use normal high efficiency air filters are an air filtration equipment in clean systems, which can achieve particulate filtering efficiency of 0.3 μm in the air 99.5 % above. Mainly applied to high cleanliness of electronics, pharmaceuticals, food, precision instruments. Its transportation, installation, etc. must be carried out in strict accordance with this requirements to ensure that the filter can be properly and reasonably used. Second, high efficiency air
High-efficiency air filters have been widely used in clean workshops in medical, electronics, fine manufacture, biomedicine and other industries. High efficiency and ultra-efficient filters are used in the end of the clean room. The seal of the high-efficiency air filter is directly related to the cleanliness of clean space. What method can be used to improve the sealing effect of the high-efficiency filter? The following is a sealing effect of Shandong Xinli to improve the sealing effect of high-efficiency air filters: 1. By using a negative pressure leakage seal method, the pollution air of the positive pressure space is transmitted to the work area. Pressure space to ensure that the work area is not polluted. 2, liquid tank sealing method, this method is in the groove frame, injecting the sealing liquid, insert the mouth of the high-efficiency filter into the sealing liquid, so that the air passage on both sides is blocked, and the sealing purpose is achieved. This sealing method is reliable, and the filter is convenient, usually applied to 100, 10 and higher.
