Water is an important resource for people to survive and develop. Life originated from water, and water is the most common component in the human body. Human life activities require the participation of water. A person can go without eating for a week, but he cannot go without drinking water for a week. But now with the development of science and technology and the continuous changes in the environment, our drinking water resources have also been polluted, so purifying water is a very important issue. The purification of water is inseparable from Japan Ro reverse osmosis support cloth.
RO reverse osmosis technology works by pressurizing. Allowing water molecules to pass through the RO membrane (at the same time, it can well remove calcium, magnesium, small bacteria, organic matter, inorganic matter, metal ions and radioactive substances in the water that are harmful to the human body), because the filtration accuracy of the RO membrane is very high High, so it can achieve the purpose of purifying water quality.
Generally speaking, RO membranes are composed of three layers: 1. Polyester material reinforced non-woven fabric (about 120μm thick) with hard, smooth texture without loose fibers surface, which can provide structural strength to the composite membrane. 2. Porous middle support layer of polysulfone material (about 40μm thick)
Because when the very thin separation layer is directly compounded on the non-woven fabric, the surface is too irregular. And the pores are too large, so it is necessary to pre-coat a layer of highly water-permeable microporous polysulfone on the non-woven fabric as an intermediate support 3. The polyamide material has a very thin separation layer (about 0.2μm thick)
The very thin separation layer is the functional layer that truly has separation effect in the reverse osmosis and nanofiltration processes. This high degree of cross-linking also ensures that it has good physical strength and resistance to chemical and biodegradation.
The Japanese Ro reverse osmosis support cloth currently supplied is the support material of Ro reverse osmosis technology, Japanese Ro reverse osmosis support Clothis a kind of non-woven fabric, which directly uses polymer slices, short fibers or filaments to form the fibers into a web through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and then through Non-woven fabric formed by post-finishing. Wet-laid non-woven fabrics open fiber raw materials placed in a water medium into single fibers, and mix different fiber raw materials at the same time to form a fiber suspension slurry. The suspension slurry is transported to the web-forming mechanism, and the fibers are formed into a web in a wet state. Reinforced into cloth. Interested parties can enter the store and contact us.
