I. Overview:

During the meltblowing nonwoven fabric production process, electrostatic charging is required. We have changed from the previous electrostatic charging to water charging. The water charging process involves using a high-pressure pump to deliver pure water to a fan-shaped nozzle. The fan-shaped nozzle then water-jets through the meltblowing nonwoven fabric, generating an electrical charge through friction between the pure water and the nonwoven. This completes the water-jet electrostatic charging. After the water-jet process, i.e., the friction between the meltblowing nonwoven fabric and specially prepared pure water, a more saturated electrical charge is produced than with traditional electrostatic charging, and it is stable and durable enough!

Pure water equipment is a modern new technology that has developed in our country only in recent years. Reverse osmosis involves applying a pressure greater than the osmotic pressure to a solution, allowing water to pass through a specially designed semi-permeable membrane and be separated from the solution. Since this process is the opposite of osmosis, it is called reverse osmosis. By using reverse osmosis methods that exceed the osmotic pressure of various materials, a solution can be separated, extracted, purified, and concentrated. Reverse osmosis units primarily separate ions from the solution, require no heating, and have no phase change processes, thus consuming less energy than traditional methods. These units are compact, easy to operate, and have a wide range of applications. Using reverse osmosis units for industrial water treatment consumes no large amounts of acids or alkalis, produces no secondary pollution, and has low operating costs.
