Liquid filter bags have many applications in chemical industry.For example,chemical catalyst recovery, filtration of piping system impurities, polishing process media, alkaline and acidic liquids, and filtration of solvents, emulsions and dispersions, removal of gel, acrylic and viscose emulsions in resins. In chemical industry, activated carbon or catalyst removal is a typical example of a high standard of applications in chemical processing.
1. Recovery of activated carbon: In the process of chemical production, we usually use activated carbon to absorb the odor and color in the liquid. In this process, the activated carbon will be fully dissolved and dispersed into the liquid, which will require fineness. The chemical filter bag is used to filter the activated carbon in the liquid and fully filter to make the chemical liquid reach the customer’s satisfaction.
2. Catalyst recovery: Catalysts are widely used in the chemical industry – both in wastewater treatment, pharmaceutical industry, and electronics industry. The use of a catalyst to speed up the process will react with the liquid to form a new suspension. At this time, a fine chemical filter bag is used to filter the suspension formed by the catalyst reaction, and the remaining unreacted catalyst remains. Chemical filter bags are the most suitable filtration products.
3. Oil-added coating: Chemical filter bags are the most widely used filtration method in the production of paints and coatings. Since pigments, resins, tackifiers, etc. are added to the special manufacturing process of paints and coatings, it is necessary to use a chemical filter bag to filter the gelatin of the internal resin, grind the particles of the pigment, and store contaminants.
