PP Melt-blown Cartridge

Introduction

Meltblown cartridge is the use of all polypropylene materials, after heating meltblown, spraying, traction, receiving technology, so that the polypropylene fibers rely on self-adhesion to form each other three-dimensional curvature of the microporous structure, with the distribution of fibers in the traditional fabrics and carding into the network of non-fabrics are different, with a larger surface area, higher pore rate, more subtle aperture, with a high degree of filtration precision, high flow rate, small differential pressure, large dirt-holding capacity, small volume, high pressure resistance, Corrosion resistance and other characteristics. 

Due to the fiber diameter and density in the direction of the diameter of the filter element to change controllably, the finished product made of the filter element will form a multi-layer gradient structure with inner density and outer looseness, the filter element in the premise of ensuring filtration effect, has a long service life, through the improvement of the design of the filter element is impurity-containing fluids are shunted, so that the impurities in the cartridge layer by layer to be retained. The filter cartridge is a multi-layer rolled structure consisting of a polypropylene media and a diversion net. The precise distribution of holes in the media precisely distributed holes in the media help to maximize the flow of fluids between the layers.

Features of meltblown cartridge

1. Extremely long service life, 4 times higher dirt-holding capacity than surface filtration products.

2. All polypropylene material cartridge, wide range of chemical resistance.

3. Wide range of precision options (1-70um).

Application Fields

1. Pharmaceutical industry: pre-filtration of all kinds of injections, medicinal liquids and injection washing water.

2. Food industry: filtration of liquor, beverage and drinking water; and

3. Electronic industry: pre-filtration of pure water and ultra-pure water; and

4. Petroleum and chemical industry: filtration of various organic solvents, acids and alkalis, and filtration of oilfield water injection.

Q&A

Q1: What applications are PP melt-blown cartridges used for?

A: Common uses include:

• Water treatment (pre-filtration for RO systems, sediment removal).

• Food & beverage (pre-filtering liquids like syrup or beer).

• Pharmaceuticals (clarifying process water).

• Industrial fluids (coolants, oils, chemicals).

Q2: How do I choose the right micron rating for my PP filter?

A: Select the micron rating based on your target contaminant size:

• 1–5 microns: Fine particles, rust, or silt.

• 10–20 microns: General sediment removal.

• 50–100 microns: Coarse pre-filtration.

Q3: How often should PP melt-blown filters be replaced?

A: Replacement depends on:

• Flow rate drop (pressure increase).

• Contaminant load (visible discoloration/clogging).

• Application (typically 3–6 months for standard water filtration).
