Filter Bag

Bag filter has the outstanding characteristics of economical filter consumables, small filter pressure drop, and convenient replacement operation. It is suitable for most conventional precision filtration occasions. The filter bag is the core of the BT series of bag filters, which directly determines the filtration performance and product quality. Jiucheng Industrial selects high-quality filter substrates to optimize the ratio, which can fully meet the strict requirements of precision filtration. All filter bags are made in a clean production environment and pass strict quality control procedures.

Filtration performance and stable quality are the two main characteristics of Jiucheng filter bags. Choosing Jiucheng filter bag means choosing a highly effective and reliable filtration process.

Deep filter type and mesh surface filter type

Deep filtration: The filtration layer is composed of fine fibers crisscrossing vertically and horizontally according to specific laws, which is suitable for intercepting small solid particles and some soft impurities, and has an obvious clarification effect. It is a one-time

Filter consumables. Deep space has a stronger ability to hold pollution. Suitable for medium and low viscosity, high-precision liquid filtration requirements. Mesh surface filtration: The filter layer is composed of a smooth mesh woven by monofilament. The surface openings are usually square holes, which are suitable for intercepting larger hard particles. Particles larger than the filter pore size can be completely intercepted, and particles smaller than the filter pore size are better to pass through , Plays the role of fixed value screening, the surface filter cake is easy to peel off and clean, the mesh filter material can be reused several times after cleaning.

High-precision and high-efficiency deep filter bag The filter bag is designed for high-precision filtration. The filtration efficiency is very high, the clarification and filtration effect is good, and the filtration flow of the same-level filter element with expensive filtration performance is 710 times that of a single 40-fold filter element. It is easy to install and replace, and optimize the ratio. The gradient filter layer has a pre-filtering function, which can hold up more dirt and save the cost of consumables.

The filter bag is made of polypropylene filter material and does not contain any release components that may contaminate liquids such as silicone oil, adhesives, etc.; gradient filter layer includes: melt blown polypropylene pre-filter layer, multilayer composite polypropylene fine filter membrane, external protection The layer is good at filtering very fine particles, even soft particles such as colloids, organic impurities, etc., enough depth space can intercept the soft particles in the filter fiber. In traditional filter elements, soft impurities are easy to paste into a layer on the surface, ending the life of the filter element in advance, or squeezing through the filter layer, and the filtering effect cannot be achieved. The filtering area is 0.5 square meters. Optional filter material: PB.

Large flow filter bag The large-flow filter bag is a new product of Jiucheng Company. Compared with the traditional No. 2 filter bag, the outer size of the filter bag is unchanged, but the filter area is doubled, up to 1 square meters, with twice the flow or dirt holding capacity. The large flow filter bag can reduce the frequency of replacement and reduce the downtime and replacement cost, and reduce the waste of liquid stored in the bag when the filter bag is replaced.

The filter bag is used with a specially designed support mesh basket, which has high strength and high safety. Optional filter materials: PP, PE, NO, PB. Deep filtration type filter material, suitable for precision filtration of nominal precision level, removes tiny solid particles, can play a clarification role, and has a large amount of capacity.

The surface of the filter material is treated with advanced calendering and singeing technology to make it smooth and flat to prevent the fiber from falling off. PP polypropylene: used for liquid filtration in the chemical industry, with very good acid and alkali resistance, filtration accuracy 0.5200μm, working temperature <90℃

• PE polyester: commonly used filter material fiber, good chemical resistance, filtration accuracy 0.5200μm, working temperature <150℃.

• NO: Good resistance to chemicals (except acid resistance), filter accuracy range: 251250μm, working temperature <165℃.

• PB polypropylene composite high-precision filter material (code PB).

• Deep filtration type filter material, suitable for high-precision precision filtration, with a precision of 125μm. The filter layer is composed of multiple layers of ultra-fine melt blown fibers and optimized filtration membranes, which can filter extremely small particles with very high filtration efficiency.

1. Corrosion resistance, Good resilience but nylon filter cloth is not acid-resistance.

2. Conductive performance is poor, heat resistant in 130-150 °C.

3. Wear resistance is very good.
