Factors affecting the performance characteristics of PP cotton melt blown filter element
In terms of water quality, the requirements for PP cotton melt blown filter elements are very strict, which may be related to the main performance characteristics of PP cotton melt blown filter elements. Therefore, only by understanding the performance of the PP cotton melt blown filter element can we better control its requirements for water quality.
Main performance characteristics of PP cotton melt blown filter element:
The PP cotton filter element mainly plays the role of pre-purification in the equipment. Generally, polypropylene material is used. The filter element is a precision consumable. It must be replaced after the first stage of use. The replacement time is about 1 year. The specific replacement time should also take into account the local water quality.
Its main function is to remove impurities, bacteria, viruses, rust and other harmful substances in the water larger than 5 microns.
The filter element has a certain service life, so you must operate it correctly in accordance with the instructions during use to avoid damage to the PP cotton filter element, causing the water purifier to be unusable or the water quality does not meet the standard.

The main requirements of PP cotton filter element for influent water quality:
If the inlet water pressure is too high, a pressure reducing valve needs to be installed in front of the water purifier. If the inlet water pressure is too low, a booster pump needs to be added.
The PP cotton filter element also has certain requirements for the inlet water temperature. The inlet must use normal temperature tap water instead of hot water. Install a water purifier before heating devices such as a water boiler;
During installation, the installation position of the water purifier should be lower than the position of the water boiler to prevent the steam from the water boiler from entering the water purifier and causing damage to the filter element.


Where are the advantages of PP cotton filter?
Among all kinds of water filter elements, the PP cotton filter element stands out for no reason, which is inseparable from its advantages. Below, let us take a closer look at the advantages of PP cotton filter in combination with the actual situation.
1. It can remove various particulate matter in water.
The water flows from the outside of the pp cotton to the inside and passes through layers of filtration. The closer to the inner layer of the filter element, the smaller the pore size, the higher the filtration accuracy.
When particulate impurities pass through the pores of the PP filter element, bridging will occur. Even particles smaller than the pores can be blocked, thus removing various particulate impurities in the filtered liquid.
2. Multi-layered deep structure, large pollution holding capacity.
The fiber of the outer layer of the PP cotton filter element is relatively thick, and the fiber of the inner layer is relatively thin. The outer layer of the boiler is relatively loose, and the inner layer is tight, forming a multi-layer gradient structure with a gradually tightening diameter. Each layer of this multi-layer structure can intercept and store impurities in the water, and when many layers add up, the dirt holding capacity will be large.
3. Large filtration flow and small pressure difference.
The polypropylene fiber, the raw material of PP cotton, relies on self-adhesive entanglement to form a three-dimensional tortuous microporous structure. It is different from the fiber distribution in traditional fabrics and carded nonwovens. It has a large specific surface area and a high Porosity.
The large surface area and many small holes allow water to pass through the PP cotton quickly, without too much difference in height between the inside and outside of the water, so not only the filtration flow is large, but the pressure difference is also small.

4. No chemical adhesives, more sanitary and safe.
Polypropylene undergoes melt-blown, traction, and receiving technology to make polypropylene fibers intertwined with each other through self-adhesion to form PP cotton filter elements of different shapes and sizes.
Unlike other filter elements, the bonding of PP cotton filter elements does not require other materials. Because the chemical composition of PP is clean and meets the food hygiene standards, it will not cause secondary pollution to the liquid to be filtered due to the material, and it is more secure to use.
5. Good chemical stability, resistance to acids, alkalis, organic solvents and oils.
The chemical stability of PP cotton is closely related to its raw material polypropylene. The chemical stability of polypropylene is very good, except that it can be corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical agents. Because of this performance, pp cotton is used in various fields such as chemistry and electronics.
6. It integrates surface, deep, coarse and fine filtration.
Due to the multiple advantages of PP cotton, it has the characteristics of large flow, corrosion resistance, high pressure resistance, and its cost is not very high. It is widely used in pure water, food and drinking water pre-filtration treatment, and RO machine penetration pre-filtration. Processing etc.
