How to choose the right liquid filter bag


Latest company news about How to choose the right liquid filter bag

Water treatment companies use needle-punched filter systems manufactured with special chemical fiber ratios to ensure the balance and precision of filter bags. The opening ratio is stable, the compressive strength is high, and the efficiency is stable. Use longer. The special wool ignition fluid can not only effectively prevent the pollution of the environment from chemical fiber decontamination and excessive leachate, but also prevent the traditional rolling liquid from clogging the filter holes and reducing the service life of the filter bag. In addition, when the liquid flows into the filter bag, due to the principle of depth filtration, the particles will stay on the inner surface and deep level of the liquid filter bag, and the capture efficiency of solid or colloidal solution particles is high.


Polyester (PE) has good performance indicators at room temperature and is a key filter system in basket filters. Under the dry and manic standard, it can withstand the working temperature of 130°C; continuous work over 130°C will harden; fade; ductile, and the temperature will also weaken its compressive strength. Polyester has good organic-chemical reliability, good corrosion resistance and resistance to most strong acids and alkalis. Insoluble in general organic solvents at high temperature, good hydrophilicity. In addition, it also has good electrical insulation, impact resistance and cold resistance. The accuracy range is 1-200 microns.


Polypropylene (PP) has good corrosion resistance and high elastic turnover. It is an excellent thermosetting chemical fiber. Polypropylene felt is commonly used in ultra-low temperature single-pulse liquid filter bags in smelters and chemical industries. Pharmaceutical company's monopulse liquid filter bag. Through the working temperature of 130°C, the temperature resistance is less than that of polyester. Polypropylene is known to have good organic-chemical reliability. Except for sulfuric acid and concentrated nitric acid, other chemical substances are relatively stable and have good antirust effect. While the derivatives of low molecular weight hydrocarbons and aliphatic hydrocarbons can soften and swell PP with an accuracy range of 1-200um.
