Single S Spunbond Nonwoven Machine
Non-woven machinery mainly includes: non-woven bag machine, non-woven slitting machine, non-woven surgical garment machine, non-woven filter cotton weaving machine, non-woven shoe cover machine, non-woven glove machine, non-woven Cloth cover machine, non-woven doctor cap machine, non-woven nurse cap machine, non-woven pillow cover machine, non-woven eye mask machine, non-woven perforating machine, non-woven rewinder and other machines.The single S non-woven fabric production line is to extrude and stretch the polymer to form continuous filaments, then spread the filaments into a web, and then the web is self-bonded, thermally bonded, chemically bonded or mechanically reinforced. The fiber web becomes a non-woven fabric, which is durable and disposable. Insulating and conductive. Softness and stiffness. Density and expansion. Isotropic, anisotropic. Filterability, breathable and impermeable. Elasticity and stiffness. Light, loose and warm. Thin as a cicada's wings, thick as felt. Waterproof and breathable. Ironing, stitching, and compression molding. Flame retardant and antistatic. Water-permeable, waterproof, abrasion-resistant, and flocking. Wrinkle resistance, good elasticity, high moisture absorption, water repellency and other characteristics. It is mostly used for packaging materials and can be reused. It is an indispensable environmental protection material for the emerging society. The most common is shopping bags.

After more than 20 years of development, China's water treatment equipment is gradually maturing. To catch up with the technological level of the developed countries, under the guidance of water supply and drainage technology theory, we must constantly increase our own research and development capabilities and cleverly select and digest foreign advanced water industry equipment from the late 1990s. The gap between China's water treatment equipment and foreign countries is greater than the gap between water crafts and foreign countries, and the gap between theoretical research and manufacturing of water special equipment and foreign countries is greater than the gap between general equipment and foreign countries. To improve the level of water treatment in China, the key is to improve the level of water treatment equipment, in particular to improve the level of water treatment equipment, which is the top priority for China's water industry.
Many years of engineering practice have clearly demonstrated that the normal operation of water treatment equipment is the basis and guarantee for the completion of the process route. The quality and longevity of the water treatment equipment are the key to the success of the project construction and operation. The price of the water treatment equipment is important for the total project cost. The impact of innovation in water treatment equipment plays an active, complementary and perfect role in the development of new technologies. Therefore, the key to the success of water treatment projects is equipment, which has become the consensus of the industry.
At present, water treatment equipment is generally divided into general equipment and special equipment. General equipment includes pumps, fans and valves. Special equipment is the focus of water treatment research. It mainly includes pollution control equipment, sand and mud scraping equipment, aeration and mixing equipment, pharmaceutical and disinfection equipment, and concentration and dewatering equipment. In recent years, additional membrane processing equipment has been added. Energy-saving and biogas utilization equipment, water reuse equipment, sludge disposal and solid waste treatment equipment.
The overall development direction of water treatment equipment is to develop new types of special equipment for water treatment, and the new type of special equipment for water treatment should fully reflect humanization, environmentalization, and modernization. In terms of sewage treatment and its recycling, the focus is on the following aspects: First, sludge disposal (sludge thermal drying equipment, sludge incineration equipment, etc.), and second, deodorization (chemical deodorization equipment, Biological deodorization equipment), the third is disinfection (UV disinfection equipment, ozone disinfection equipment and chlorine dioxide disinfection equipment), and the fourth is recycling (dosing equipment and membrane processing equipment - microfiltration, ultrafiltration and reverse osmosis devices), the fifth is Energy-saving new technology and support, and sixth, improvement of traditional processing equipment.
The process is the dominant, the equipment is the foundation, the process is the precondition for determining the equipment, and the equipment is the guarantee of the process. The overall trend in China's water treatment is that the practice of importing equipment has gradually shrunk, and localized equipment is rapidly emerging. At the same time, by optimizing the configuration, the configuration is more humanized, environmentalized, and modernized. This is a sign that reflects the modernization level of water treatment, and it is a guarantee for saving investment in engineering, reducing energy consumption, and operating reliability.
After years of hard work, China's technical specifications, standards, and design in the field of water treatment equipment have gradually reached proceduralization and standardization. It can be believed that after the efforts during the “11th Five-Year Plan†period, the overall technical level of China’s water treatment equipment will surely reach the international advanced level.
The Fifth World Water Assembly Equipment Exhibition undoubtedly provided us with a good opportunity to learn from the advanced experience and technology from abroad.
