What are the characteristics of melt blown filtration?

2022-01-24 Page view : 38 views

Melt-blown filter element is a tubular filter element made of non-toxic and odorless polypropylene particles after heating, melting, spinning, drawing and receiving. If the raw material is mainly polypropylene, it can be called PP melt-blown filter element.

It is not only used in water purification in large quantities. It also has excellent chemical compatibility and is suitable for filtration of strong acids, alkalis and organic solvents. Strong dirt holding capacity, long service life and low cost.

 

Performance Characteristics:

1.) Using polypropylene as raw material, it is made of continuous polypropylene long fibers produced by melt-blown process.

2.) High filtration accuracy, large flow, uniform structure, large dirt holding capacity and long service life

3.) It has good chemical compatibility, without any additives, the fibers are not easy to fall off

4.) It is widely used

 

High Dirt Retention Capacity:

In the depth of the entire filter element, the effect of grading and capturing particles by density is realized, so that the efficiency of the filter element can be brought into full play; higher dirt retention capacity means long service life, low replacement frequency and cost savings; the surface density of the filter element is The density gradually increases from the surface to the center of the filter element; there are no surface blind spots that reduce the flow rate of the filter element and increase the frequency of replacement.

 

Pure Polypropylene Structure:

High temperature bonding fiber; does not contain humectants, antistatic agents and binders, etc.; a wide range of chemical resistance; easy to handle after incineration; meet the requirements of the FDA food and beverage industry; will not produce leachable and emissions.

 

Technical Parameter:

Filtration Precision: 1μm, 3μm, 5μm, 10μm, 20μm, 30μm, 60μm;

Applicable PH: 1~13;

Maximum Differential Pressure: forward 0.4Mpa;

Working Temperature: under 0.25Mpa, <70°C;

Sterilization: resistant to 126°C, online steam sterilization for 30 minutes;

Endotoxin: The water extract of the filter column is tested by 1AL, and the endotoxin content is less than 0.5EU/ml.

 

Application Field:

Pharmaceutical Industry: pre-filtration of various injections, liquid medicines and injection bottle washing water, pre-filtration of large infusions and various antibiotics and traditional Chinese medicine injections.

Food Industry: Filtration of alcohol, beverages, drinking water.

Electronics Industry: Pre-filtration of pure water and ultrapure water.

Petroleum And Chemical Industry: Filtration of various organic solvents, acids and alkalis, oil field water injection filtration.
