The filter characteristics indicators have four, namely, speed, filter speed, efficiency, resistance, and dust. Of course, there are other indicators, such as weight, power and regeneration characteristics, etc. These indicators are mainly related to filter materials, so what filter material manufacturing filter is the most important part of the development of filters. In addition to the determinants of filter materials, the structure of the filter is also an important factor. For example, a filter material makes a flat filter or a multi-bag shape or wedge filter, which is very different in resistance and dust removal, so it is a reasonable and optimal structure, and it is another important part of the development of the filter. . Resistance: The fibers turn the airflow to the airflow to produce minute resistance. The sum of the resistance of countless fibers is the resistance of the air filter. The air filter resistance increases with gas flow, by increasing the air filter material area, the relative wind speed of the filter material can be reduced to reduce the air filter resistance. Space and filter speed measuring filter
There are many kinds of air filters, filtering features, different fields, what is the PTFE high-efficiency filter? Where is his characteristics and application fields? First PTFE is PTFE (Poly Tetra Fluoroethylene), a short written PTFE, commonly known as \"Plastic King \", is a polymer polymer prepared as monomeric polymerization. White waxy, translucent, heat resistance, excellent cold resistance, can be used for a long time of -180 ~ 260oC. Such materials have an antide-resistant alkali, and the characteristics of various organic solvents are hardly soluble in all solvents. At the same time, polytetrafluoroethylene has a high temperature resistant to high temperature resistance, which is extremely low, so it can be lubricated, and it has become an ideal coating of the inner layer of easy cleaning water pipe. The PTFE high-efficiency filter is a high efficiency air filter made of PTFE film filter. He has high efficiency, pressure
1. The basic knowledge of the filter is the main purification device of the clean room, which is the main means of air purification. Therefore, it is very important for the basic knowledge of clean room design, construction, and maintenance management to understand and master the filter. A. The classification of the filter is divided according to the performance of the filter (efficiency, resistance, dust removal), usually divides it into a coarse, alive, high-efficient, sub-efficient, efficient (HEPA) and ultra efficient (ULPA) Six types of filters.
High efficiency filter: Mainly used to capture particulate dust and various suspensions of 0.5 μm or less. Using ultrafine glass fiber paper, rubberized paper, aluminum film and other materials are used as a split plate, and is glued to the outer frame of the aluminum alloy. Each unit is tested by the gas method, with high filtering efficiency, low resistance, and high dust removal. High efficiency air filters can be widely used in optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, medical institutions, air-conditioning ends of dust-free water purification workshops, etc.. Efficient and super efficient filters are used in the end of the clean room, which can be divided into the form of a structure: there is a separator, high-efficient, high-wind, high-efficiency filter, etc. In response to the selection of the initial, medium-end, efficient air filter, should also be made with reference to these four performance parameters. 1 Select a filter with a large filter area. The larger the filter area, the lower the filter speed,
The nylon mesh primary filter is generally used in the primary filtration system of central air conditioners and household air conditioners. It has the advantages of large air volume, low resistance, repeatable cleaning, and long service life.The nylon mesh filter adopts a lightweight plate structure, a reusable metal aluminum frame, wear resistance, long service life, high strength, good comprehensive use effect, simple and beautiful filter structure, low initial resistance, strong dust resistance, and It is cleaned and reused many times, easy to replace and safe, and users can operate by themselves, which is simple and convenient.And non-standard customization can be made according to customer needs, and it can also be used in multiple groups with buckle/handle interconnection, which is easy and safe to replace.
