Recently, at the 2023 China Membrane Industry Annual Conference, our company's patent "Wet Non woven Fabric and Preparation Method for Water Treatment Reverse Osmosis Membrane Support Substrate" won the 2023 "China Membrane Industry Patent Gold Award". This honor is a high recognition from the Chinese film industry for Nissin Hengli's wet non-woven fabric products and technology.

After several years of development, the Chinese reverse osmosis membrane application market has grown rapidly, accounting for 30.6% of the global reverse osmosis market. At the same time, the pace of domestic substitution is accelerating, constantly breaking through the monopoly of high-end reverse osmosis membrane materials by international brands. However, as a key raw material for reverse osmosis membranes, non-woven fabric is almost completely monopolized by Japanese and American brands. This situation seriously restricts and affects the international competitiveness of terminal products in China's reverse osmosis membrane production industry and water purification industry.

Through more than three years of independent technological research and development, Rixin Hengli has broken through multiple technical barriers, formed a large-scale production technology for wet non-woven fabrics with completely independent intellectual property rights, fully mastered the relevant core technologies from formula, process to production equipment, and achieved mass production of high-end non-woven fabrics with an annual output of 20 million square meters. The product has been verified in large quantities by users and can completely replace imported brands to meet the performance requirements of reverse osmosis membrane materials. The monopoly of international related products in the domestic market has finally been broken. Rixin Hengli is currently the largest wet non-woven fabric manufacturer in China, and also the first wet non-woven fabric manufacturer in China to be widely used in reverse osmosis membrane manufacturing.

The Nissin Hengli wet non-woven fabric is comparable to imported products in terms of breathability, product cleanliness, surface smoothness, tensile strength, and has solved the problem of curling or wrinkling on the coating surface of Japanese non-woven fabric after the coating layer is cured. The product performance has received unanimous praise from multiple reverse osmosis membrane manufacturers. Through recent years of research and development innovation and data accumulation, the company has acquired the ability to customize for customers and develop non-woven fabric products according to their personalized needs.

Rixin Hengli is committed to the research and development, production, sales, and service of membrane materials and components such as microfiltration membranes (MF), ultrafiltration membranes (UF), nanofiltration membranes (NF), reverse osmosis membranes (RO), and special separation membranes (SF). The company focuses on the water treatment industry and has gradually formed a complete portfolio of water treatment products through technological research and cooperation. It will strive to become an internationally leading manufacturer of full film products and an integrated solution service provider.

In recent years, the company has continuously increased its investment in technological innovation, maintaining R&D investment accounting for over 8% of revenue. It has also established an enterprise academician workstation with Professor Chen Feiyong, a foreign academician of the Japanese Academy of Engineering, and a postdoctoral workstation in Zhejiang Province. The company has applied for more than 60 patents and obtained nearly 30 authorized patents. In 2023, the company was awarded the title of National Specialized, Refined, Unique and New "Little Giant" Enterprise.

In the future, the company will use wet non-woven fabric as the carrier, special separation membranes as the entry point, reverse osmosis membranes and nanofiltration membranes as the main focus, and continuously innovate in the fields of household water purification, industrial ultrapure water, zero discharge of industrial wastewater, seawater desalination, special material separation and recycling, salt lake lithium extraction, etc., constantly exploring domestic and foreign markets and contributing to the localization and substitution of China's water treatment membrane industry.
