As a member unit of the China Rubber Industry Association, Qingdao Huahai Environmental Protection Industry Co., Ltd. has gone through more than a decade hand in hand with the association.Over the past decade, the company has always adhered to the development philosophy of "Environmental Protection Empowers the Upgrading of the Rubber Industry". By deeply integrating into the industrial ecosystem, it has continuously focused on the R&D of rubber environmental protection technologies, the innovation of green products, and the joint development of industry standards, emerging as a crucial driving force for the green and sustainable development of the rubber industry.
Over a Decade of Membership: Growing and Progressing Together with the Industry
Since joining the China Rubber Industry Association, Qingdao Huahai Environmental Protection Industry Co., Ltd. has always actively participated in various activities organized by the association. Through these platforms, the company has timely kept abreast of the latest policy trends, market dynamics and cutting-edge technological information in the rubber industry, and established close cooperative relations with many well-known enterprises and scientific research institutions in the sector.
Core Business Areas: Focusing on Rubber Environmental Protection, Forging Professional Quality
Qingdao Huahai Environmental Protection Industry Co., Ltd. focuses on the R&D and provision of environmental protection solutions for the rubber industry, with its core business mainly covering two major segments:
Qingdao Huahai Environmental Protection Industry Co., Ltd. is a drafting unit for the industry standards?Impregnated Canvas for Rubber Dams?and?Rubber Dam Bags. The process design, manufacturing, inspection, transportation, installation and commissioning of Huahai rubber dams are all strictly implemented in accordance with the water conservancy industry standards?Technical Specifications for Rubber Dams?(SL227-98) and?Rubber Dam Bags.
After long-term research, testing and verification, Huahai has adopted a new technology—specifically the?stepped lap molding method—which is particularly suitable for the production of extra-thick and extra-high rubber dams. This method has achieved a qualitative leap in both the internal and external quality of dam joints: it delivers high bonding strength, a smooth surface finish, an aesthetic appearance when the dam bag is inflated, easy and convenient installation, and excellent water-stopping performance. Huahai’s stepped lap molding technology and raw lap joint technology for rubber dams have obtained national invention patents.
The airbag of Huahai’s air-shield dam adopts the integrated one-time molding lamination and integrated one-time vulcanization process. This technology enables the airbag wall to form a seamless composite structure with excellent air tightness and balanced strength in all directions, which greatly enhances the elasticity of the airbag, improves its burst resistance and impact fatigue resistance, and extends its service life.
After long-term research, testing and verification, Huahai has developed a new technology, and its invention—the anti-tearing rubber airbag for air-shield dams—has obtained a national utility model patent.
Future Outlook: Anchoring the Green Future and Continuing the Chapter of Cooperation
Having been a member of the China Rubber Industry Association for over a decade in a row, this long-standing recognition serves as the best testament to Qingdao Huahai Environmental Protection Industry Co., Ltd.'s strength. Our ability to stand firm amid industry evolution and gain consistent recognition from both the association and peers not only demonstrates our core competitiveness in technological R&D and product quality, but also testifies to the profound foundation of our sound operation and dedicated commitment to the rubber dam sector.
