Today we simply introduce the characteristics of filter cloth for everyone.
1. Selection of filter First of all, according to the fluid to be filtered under the title of chemistry, chemical taboo to find out the available filter media, and then for its operating temperature, operating pressure, pH, operating conditions (eg, can withstand steam , Hot water or chemical sterilization, etc.), one by one evaluation, and remove the filter does not apply. Use is also an important element of thinking, such as drugs, food or cosmetics used in the filter must be FDA-approved material; ultra-pure water, you have to choose pure, free from emissions will affect the impedance of the filter; filter gas is Must choose the hydrophobic material and the ability to demand "sanitary filter" design and so on. The company is located in:
2. Filtering accuracy This is one of the most disturbing issues. For example, to remove macroscopic particles, choose 25 micron filter; to remove liquid cloud, use 1 or 5 micron filter; to filter out the smallest bacteria need 0.2 micron filter. The problem is that there are two types of filtration units: absolute accuracy / nominal accuracy Absolute accuracy refers to 100% of the particles can be filtered out of the marked accuracy. For any kind of filter, this is simply a specification that is impossible to reach, and not practical, since 100% is a immense value. Commonly known as the market on the absolute filter such as film, etc., strictly speaking, can only be called "approaching absolute" filter, while others are all nominal accuracy, nominal accuracy, this is the main disturbance: "nominal accuracy There is no one industry to identify and comply with the norms. " In other words, Company A can set the nominal accuracy at 85-95%, while Company B prefers to be set at 50-70%. In other words, Company A's 25 micron filter accuracy may be equal to Company B's 5 micron, or finer. For this problem, experienced professional filter providers will help filter the choice of precision, and the basic approach is "trial." The company is located in:
3. According to the viscosity of the filter temperature, professional filtration equipment suppliers to calculate how much demand for the filter installed several filters, how much each filter to bear the flow rate and predict the initial pressure drop some. If you can provide the fluid content of impurities, and can predict the filter life. The company is located in:
4. The design of filtration system The title involves a wider range, such as should choose a source of pressure, how much pressure will be the full use of filter life, the ability to install two filters in parallel, with a suitable continuous operation of the system , A wide distribution of the particle size should be how to match the coarse filter and fine filter, the system can be installed check valve or other installation and so on. These require the use of units and filter cloth suppliers to work closely together to find the most appropriate design.
