Instructions for correct use of PP meltblown filter element

Instructions for using PP melt-blown filter element: 1. When the pressure difference reaches 0.2MPa, the filter element should be cleaned or replaced. 2. Install the filter element correctly. If the filtered water is found to be polluted, carefully check whether the filter element is skewed, and whether the two ends are strictly aligned and pressed. 3. The filter element is selected according to the precision of the filtered liquid and the impurities contained in it. The viscous liquid can be filtered by the second stage and the first stage of coarse filtration to reduce the resistance and prolong the service life of the filter element (usually 3-4 times). The main functions of pp meltblown filter element: 1. Removal of particulate impurities in tap water Tap water, groundwater, etc. flow from the outside to the inside. After filtering layer by layer, the closer it is to the inner layer of the filter element, the smaller the pore size and the higher the filtering accuracy. Bridging occurs when particulate impurities pass through the PP filter channel. Even particles smaller than the channel can be blocked, thereby effectively removing various particulate impurities in the filtrate. 2. Strong dirt-holding capacity and multi-level structure The outer layer of pp meltblown filter element is thicker, the inner layer is thinner, the outer layer is looser, and the inner layer is tighter, forming a multi-layer gradient structure that gradually tightens. Each layer of this multilayer structure traps and stores impurities in the water. If many layers are added, the amount of contaminants can be large. 3. Large flow and low pressure during purification PP fiber is made of polypropylene fiber, which is entangled with each other by self-adhesion to form a three-dimensional curved diameter microporous structure. It is different from the fiber distribution in traditional fabrics and non-woven fabrics, with larger specific surface area and higher porosity. The large surface area and multiple small holes can make the water pass through the pp melt-blown filter element quickly, and there is not much difference between the inner and outer water heights, so not only the filtration flow is large, but also the pressure difference is small.
