With the widespread use of water purifiers, the requirements for filter elements are also getting higher and higher. As we all know, the PP filter element is the core component of the water purifier, and the quality of the PP filter element directly affects the quality of the water produced by the water purifier. So, how could we tell the quality of the purifiers?
PP filter element, also known as melt-blown PP filter element, is a tubular filter element made of non-toxic and odorless polyester fiber particles after heating, melting, spinning, pulling, and receiving forming; if the raw material is mainly polyester fiber, it can be called a tubular filter element. Do PP filter. The main function of the PP filter element is to filter various harmful impurities with a diameter greater than 1 micron in tap water. It can effectively remove various particulate impurities in the filtered liquid; it can be multi-layered deep structure, and has a large amount of dirt; Small; does not contain any chemical adhesive, more hygienic and safe; acid, alkali, organic solution, oil, and has good chemical stability; integrates surface, deep, coarse and fine filtration; Features such as high pressure and low cost. It is used to block large particles such as rust, sediment, and insect eggs in the water. Because there is no sewage function, its service life is generally 3-6 months, so the filter element should be replaced regularly, otherwise it will cause secondary pollution problems, and the water quality cannot be guaranteed. According to the range of use, it can be divided into 10 inches to 40 inches, and can be customized according to special requirements, density, length and weight. First look at the density, according to the difference in aperture, PP can be divided into 1um and 5um, and then look at the weight of about 100g and 110g, the aperture cannot be recognized by the naked eye, and the weight and touch can be distinguished by hand. The quality of the filter element directly affects the quality and filtration effect of the water purifier, so the commonly used 1-micron and 5-micron ones are generally the best choice. At the same time, because the PP cotton filter element is generally used in the first three stages, it must be replaced regularly, otherwise the service life of the RO membrane and the TDS value of the effluent water quality will be affected.
So, is the PP cotton water purifier filter hard or soft? In fact, the higher the density, the stronger the pinch, which means that the compressibility is also high, the filtration accuracy and service life are longer, and the soft PP is in the water pressure. If it is large or used for a long time, it may disperse, resulting in a decrease in filtration degree and affecting the normal operation of the RO machine. Therefore, PP, which has an advantage in quality and price, can fundamentally improve the quality of the entire water purifier.
The quality of the PP filter element is determined by the tightness of its fibers. The internal fibers of a high-quality PP filter element are dense and uniform, and this difference is difficult to distinguish with the naked eye. So how should we distinguish?
First: look at the weight. We can measure the weight with our hands. The heavier the weight, the higher the fiber density of the PP filter element. The quality is also better.
Second: Look at compressibility. Generally, the higher the fiber density of the PP filter element, the better the compression performance, and the better the quality of the PP filter element. We can also judge by hand, the firmer the hand, the better the compression performance.
