Most liquid filter bag filtration surfaces are specially treated by special hair, which can not only effectively prevent the separation of fibers from separating from pollution filter fluid, but also avoid excessive blockage of label filter holes caused by traditional roller treatment, extending the service life of the filter bag. The materials used are all white, and the adhesion is not treated without any special drift dyeing, which fully meets environmental protection standards. It is also because acupuncture feel has very few layer efficiency, making it an efficient filtering material. The thickness of the acupuncture felt is uniform, and the opening valve is good and sufficient to make the filter bag efficiency stable and longer. Five sealing needles are closed to ensure that each filter bag can reach better filtering guarantees. It is widely used and suitable for various industrial liquid filtration.

The liquid filter bag has the following advantages:

1. Using high -speed industrial sewing machines with silicone oil -free cooling to easily solve the problem of silicone oil pollution.

2. After the stitching of the bag of the bag improves, there is no height convex, so that the side leakage has no needle eye to prevent the side leakage.

3. The labels of the product specifications on the filter bag are easy to disassembled, avoiding the pollution of the filter bag and the ink to the filter fluid.

4. The filtration accuracy is from 0.5 microns to 300 microns. The material is divided into filter bags such as polyester and polypropylene nylon.

5. Stainless steel and galvanized steel rings 氩 arc welding technology. The diameter error is only less than 0.5mm, and the level error is less than 0.2mm. The filter bag made of this steel ring is installed in the device.

6, high sealing, reduces the possibility of side leakage.

How to choose the liquid filter bag: First understand the mechanism of the cloth bag filtering system: the liquid flows from the filter bag to the outside of the bag, and the filtered particles will be cut in the bag. The working principle is pressure filtering. The bag filter system is mainly composed of filter containers, supporting net baskets and filter bags.

1. Selection of filter bag material:

First according to the fluid chemical name to be filtered, find the available filtering material according to chemical cooperation taboos, and then use the filter medium temperature, work pressure, pH value, viscosity (CPS), impurities (hard particles, soft particles), impurities (PPM) ), Operating conditions (for example, whether to resist steam, hot water or chemical sterilization, etc.). , Evaluate one by one to eliminate filter materials that are not applicable. Use is also an important consideration. For example, the filter materials used for medicines, food or cosmetics must be materials allowed by FDA; ultra -pure water must be selected from clean filtering materials, which does not contain release materials, which will affect ratio impedance. Level filtering "design and so on.

2. Selection of the accuracy of the filter bag:

This problem is annoying. For example, to remove the particles visible to the naked eye, you can choose a filter bag of 20 microns or 25 microns; to remove the clouds in the liquid, choose a filter bag of 1 to 5 microns; Essence
