Dye Separation Filter Bag

Wholesale low price Dye separation Filter Bag by Qingdao Star Machine,It is a filter device used for the filtration and separation of liquid substances such as dyes, paints and pigments.

Advantageous features of dye separation filter bags.

1. Precision filtration

The filtration precision of the filter bag covers the range of 0.5-500 microns (e.g. 1μm, 25μm, 100μm, etc. grading), which can retain the dye particles, impurities and suspended matters in the liquid through the pore size sieving effect. Example:

Polypropylene (PP) filter bag can achieve 0.1μm precision (equivalent to more than 1500 mesh) and high efficiency filtration.

Polyester (PE) filter bags are suitable for regular precision requirements (1-300μm).

Note: The filtration precision should be selected according to the size of the impurities, too high will lead to a drop in flow rate.

2. Environmental Adaptability

Support -40℃ to 260℃ working conditions, pressure resistance up to 10bar, specific performance:

High temperature environment: polytetrafluoroethylene (PTFE) filter bag can be used stably under 260℃ for a long time.

Corrosive liquids: plastic ring filter bags are acid and alkali resistant, stainless steel ring filter bags are resistant to oxidation in high humidity.

High-pressure scenarios: wire-stitched sealing filter bags are more pressure-resistant and rupture-resistant than heat-melted ones.

3.Convenient maintenance

Adopt modular design:

Replacement requires only the opening of the filter housing to replace the old bag (Typical No.2 bag flow rate up to 10m³/h).

Polyester/nylon filter bags support water backwashing and reuse, reducing consumable costs.

4.Application Scenarios

Suitable for the dye industry:

Desalination and purification of crude dye solutions (retention of large dye molecules and permeation of inorganic salts)

Dyeing wastewater treatment (removal of suspended matter and unconsolidated dyestuff)

High-pressure and high-temperature dyeing machine circulating filtration system

Service life of Dye separation Filter Bag

The service life varies depending on the material, filtration accuracy, use environment and other factors, in general, its service life can reach several months to several years.

For PE, PP and other materials of the China Dye separation Filter Bag, its service life is usually in a few months to about a year, which mainly depends on the nature of the filter liquid, filtration accuracy, frequency of use and other factors. If the environment is harsh, such as high temperature, high humidity, strong corrosion and other environments, it may shorten the service life of the Dye separation Filter Bag.

For nylon or PTFE and other materials of the filter bag, its service life may be longer, usually in a few years to decades. These materials have better corrosion resistance and high temperature resistance, and durable Dye separation Filter Bag can work well in harsher environments.

In addition, the service life of the filter bag is also affected by cleaning and maintenance. If the filter bag can be cleaned and maintained regularly to avoid overuse and damage, the service life of the Dye separation Filter Bag can be extended.
