The PP cotton sediment water filter cartridge is made of chemical fiber made of polypropylene resin as raw material, which is formed by winding and bonding of the fiber itself. The excessive precision is 5~10μm, which can screen out fine sand, rust, suspended solids and other residues in the water. Using high-precision layered melt-blown processing technology, a good PP cotton filter has a smooth surface, high winding density and weight in the hand. Give it a pinch to see the hardness. Generally, the heavier the PP cotton, the higher the hardness; the lighter the PP cotton, the softer the hardness. Because under the same water conditions, the softer the PP cotton, the less time it will be used, and the faster the disassembly and replacement cycle. Tear the pp cotton by hand, the good pp cotton sediment water filter cartridge is not easy to be torn off, and the poor pp cotton filter element will fall in pieces.
The over-accuracy of activated carbon is 0.5μm, and it absorbs different colors, odors, and organic chemicals in water, such as chlorine gas, disinfectant water, etc. The best activated carbon in the industry is coconut shell activated carbon. It can be seen with the naked eye that it is characterized by fine and well-proportioned particles, a rounded surface, and it can feel very smooth when touched by hand. Its purity is also very high. Under the microscope, it can be seen that its pores are very concentrated. When it is poured into water, it will bubble like boiling water due to the absorption of pores, while other activated carbons will only bubble a few times, so the adsorption capacity is stronger.
The most critical technology of stainless steel sediment filter is membrane for ro water purifier, which is mainly made of fiber material and is the key component to complete RO reverse osmosis. It is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. This kind of technology is relatively complicated, and it is difficult for people outside the industry to distinguish between good and bad. Then we will look at the screening results of professional institutions.
