PP filter is made of polypropylene (PP) hot melt method, its micron number from 1um to 300um. The filter element has no inner shaft and adopts the design of inner dense and outer sparse, which can not only maintain stable flow, pressure difference and service life, but also have excellent depth filtration effect and pollutant accumulation. It is a filter element with high efficiency, low pressure difference, long service life and wide applicability. Because the chemical composition of PP is clean, and in line with the food hygiene standards, will not be due to the material and the secondary pollution of the liquid to be filtered, has the characteristics of large flow, high precision, corrosion resistance, high pressure resistance, widely used in PCB, electroplating, pure water, food and drinking water pre-filtration treatment; RO pre-filter processing, etc. PP filter element is made of ultra-fine polypropylene fiber hot melt tangles. Microfiber randomly forms three-dimensional micro...

In the daily use of the core of the east water purifier products lies in the filter core, different levels of filter types and functional characteristics, the replacement cycle of the filter core will be different, so what are the common filter elements of the water purifier? Activated carbon filter (6 months) Activated carbon filter products are mainly divided into two categories, granular activated carbon filter and compressed activated carbon filter two. It is very absorbent to many substances and can change the taste of water. Granular activated carbon filter: can effectively remove the residual chlorine in water, odor, heterochromatic, etc., but also can effectively adsorb some organic macromolecules in water. Simple composition, low cost, but easy to damage carbon leakage, service life and effect is not stable, commonly used as a variety of household water purification equipment diode filtration. Compressed activated carbon filter: can deeply absorb the odor, heterochromic, resi...

The water purifier can purify the water and guarantee the health of the water. Water purifier can purify water because of its filter element, and different filter elements have different effects on water purification. A, water purifier filter element: activated carbon Activated carbon has been used for water treatment since the beginning of the 20th century. It is a carbon with a porous structure. The pores are used to increase the surface area of the activated carbon for absorbing impurities. The physical properties of carbides are closely related to their raw materials and processing processes. At present, common carbon is coal, trees, coconut shells or palm as the main raw materials. Coconut shell sintered carbon has better stability, pore distribution and surface area than other types of activated carbon, which makes it have better performance in water treatment. Activated carbon is on the surface porous tissue adsorption instead of chemical substances, organic pollution sources, ...

With people's attention to the quality of drinking water, water purification system began to enter thousands of households. The filter element of different water purification equipment is different, and the filtration effect is different. Know filter PP fiber filter element Function: The melt-blown filter core is made of polypropylene micro-fiber hot-melt entangle, the fiber randomly forms three-dimensional micro-pore structure in space, and the pore size is gradient distribution along the filtrate flow direction. It integrates surface, deep and fine filtration into one, and can hold back impurities of different particle size, remove suspended matter in water, sediment, rust, etc. The filtration accuracy is 1μm. Application: used for primary filtration of groundwater/surface water, pre-filtration of water purifier, used as the primary filter element of water purification equipment. Activated carbon filter element Function: The main function is adsorption, generally speaking, the la...

The water filter element is used in the filtration system to remove the particles and sundries in the system and ensure the cleanliness of the filtration system. The service life of the water filter element is an important problem in the filtration system, especially in the high pollution working conditions, the failure of the filter element and the resulting failure of the filtration system is particularly prominent. What are the main factors that affect the service life of the water filter element? First, filtration performance of filter element 1. Filtration accuracy: filtration accuracy refers to the filtration capacity of filtration materials for different sizes of particle pollutants. It is generally believed that the filtering accuracy is high and the life of the filter element is short. 2, the amount of pollution The pollution capacity refers to the weight of particle pollution that can be accommodated by the unit area of the filter material when the pressure drop of the fi...

Mention of filters, we are not unfamiliar, if there is no filter in our life and production, then our living environment and health will be greatly affected, it is because of these filters escort our environment will be more beautiful, health will be more secure. Filter element is the core component of filter equipment. Today, I will briefly introduce the steps of filter element cleaning. 1. The pre-processed filter element is put into the baking furnace for curve heating. In order to prevent the phenomenon of flying temperature, the temperature must be recorded every 15 minutes. 2. After the filter element is cooled to room temperature, a 10--15MPa high pressure water gun is used to wash from the outer surface of the filter element, and then reverse rinse from the tube. 3. Use deionized water to prepare 15--20 soda ash solution, the filter element into the solution heated to boiling. 4.Take out the filter element, with 10--15MPa high pressure water gun first from the outer surface of...

The filtration system plays a big role in our life. We need to filter too many impurities. It ensures a greater flow rate per unit area; Smooth external surface, impurities are not easy to stick, backwashing is easy to complete, small outside and large inside the filter precision makes impurities can not be retained in the filter core body, sludge can be pressed to 70% water content. PE filter medium is the core component of microporous filter applied in chemical, pharmaceutical and environmental protection industries. The following is to introduce the performance characteristics of PE filter element? PE filter 1, material performance: PE with UHWM-PE as the main medium has non-toxic, odorless, no foreign body out, physiological safety characteristics, in line with the requirements of GMP. 2, chemical performance: PE filter medium has excellent corrosion resistance, resistance to all kinds of non-strong oxidizing acid, alkali resistance, aldehyde resistance, adiphatic hydrocarbon resi...
