Many friends may have discovered this problem. When we buy a water purifier, many merchants will always mention the word Ro reverse osmosis, Ro reverse osmosis membrane The pore diameter is small and the interception effect is good. Filtered water tastes better and is more reliable. As Ro reverse osmosis membrane technology continues to mature, Ro reverse osmosis water purifiers have entered more and more households. This is also inseparable from the role of Japan Ro reverse osmosis support cloth.
Reverse osmosis membrane is the core component to achieve reverse osmosis. It is a kind of simulated biological semi-permeable membrane. Artificial semipermeable membrane with corresponding properties. Generally made of polymer materials. Such as cellulose acetate membrane, aromatic polyhydrazide membrane, aromatic polyamide membrane. The diameter of surface micropores is generally between 0.5 and 10nm, and the size of the permeability is related to the chemical structure of the membrane itself. Some polymer materials are good at repelling salt, but their water penetration rate is not good. The chemical structure of some polymer materials has more hydrophilic groups, so water permeates relatively quickly. Therefore, a satisfactory reverse osmosis membrane should have appropriate permeability or salt rejection rate.
Generally speaking, the RO reverse osmosis membrane filter element is placed in the fourth or fifth stage of filtration of the water purifier, and its service life will be longer than other filter elements. This is because the first few stages of filter elements filter large particles of impurities and protect the RO membrane filter element to a certain extent. However, during the use of the water purifier, you must develop the habit of replacing the filter element in time to ensure healthy water quality, extend the service life of the RO membrane, and overall save the cost of replacing the filter element.
The supplied Japan Ro reverse osmosis support cloth is the support material for RO reverse osmosis membrane filter element, Japan Ro reverse osmosis support Clothis a type ofnon-woven fabric, also called single-component spunbond non-woven fabric. Its raw material is all polyester chips, which is a non-woven fabric made of countless continuous polyester filaments through spunbond hot rolling. Generally, it is a water-repellent non-woven fabric. The water-repellent properties of non-woven fabrics vary depending on the weight. The larger the weight and the thicker, the better the water repellency. If there are water droplets on the surface of the non-woven fabric, the water beads will slide directly from the surface. High temperature resistance. Because the melting point of polyester is around 260°C, it can maintain the stability of the non-woven fabric’s dimensions in environments that require temperature resistance. It has been widely used in thermal transfer printing, transmission oil filtration, and some composite materials that require high temperature resistance. Japan Ro reverse osmosis support fabric is a water-repellent non-woven fabric. The water-repellent properties of the non-woven fabric vary depending on the weight. The larger the weight and the thicker, the better the water repellency. Interested parties are welcome to enter the store for consultation.
