Do you know why PP cotton is used in the filter element of the water purifier?

Many friends have water purifiers and discovered that the first filter layer is a PP Cotton filter element. People don't know that PP Cotton filter element is the raw material for polypropylene synthetic chemical fiber. PP cotton material is used to fill many things in our daily lives: pillows, plush toys, and air-conditioning blankets.


The water purifier's filter element also uses a PP cotton filter element. The PP cotton filter element can also be known as melt blown PP filter elements. This tubular filter element is made from non-toxic, odorless polyester fibers after heating, smelting and spinning. It also tractions and accepts.


What is the purpose of the PP cotton filter in a water purifier? Why is there so many filter elements in the beginning?


1. Filtering large particles has a positive effect


Layer by layer, the pore sizes of the pp cotton filter elements are stacked. This results in a uniform and dense pore structure and a filtration accuracy as high as 1 millimeter. Bridging occurs when particles pass through the PP filter channels. Layer after layer can effectively block even smaller particles than those at the beginning. Large particles of impurities like sediment and rust can be effectively blocked by pp cotton.


2. Large amount of pollution from multi-layer deep structure


The PP cotton filter element's outer fiber is thicker than the inner fiber. The pore size is smaller the closer the outer layer is to the inner. This multi-layered deep filter structure can be advanced layer by layer, effectively blocking all impurities. It has a high tolerance for impurities and is highly resistant to pollution. This layer filters 80% of impurities that are filtered by the water purifier.


3. Large filtration flow, small pressure difference


We know from experience that water pressure can have a significant impact on filter performance. By self-bonding, the PP cotton filter elements become entangled together to create a three-dimensional curved microporous shape. This structure has large surface area and high porosity. The filter allows water to flow quickly through it, so the difference in height between inner and outer water is minimal and the pressure difference small. Normal circumstances do not call for an additional booster device for the PP cotton filter element.


4. It doesn't contain any chemical adhesives so it is safer


Users can be confident in the PP cotton filter element. It is heat-resistant and can be wire-drawn, wire-sprayed, wire-drawn, and shaped. There is no risk of it being contaminated or affected by other materials. It is safe and secure because it meets all food-grade hygiene standards.


5. It is chemically stable.


The chemical stability of polypropylene is determined by the relationship between polypropylene raw material and polypropylene yarn. Other chemical agents, such as concentrated sulfuric acid or concentrated nitric acids, are stable and resistant to acids, alkalis and organic solvents. Secondary pollution is not an issue as the filter element.


A PP cotton filter element integrates both surface filtration as well as deep filtration. Fine filtration includes the primary filter. It is corrosion resistant, low cost, and has a large flow rate. It is responsible for the first stage in water purifiers.


The PP cotton filter element has 80% of the water purifier's filtering power, which is why it is so easy to filter. It is also very durable. If the water quality is poor, then the filter element will need to be replaced every 3-4 months. The best area should not last more than 6 months. This is primarily based on the current situation.
