Company Profile
Yantai Sunny Rubber Co., Ltd established in 2005, located in Economic Development Area of Qixia City, Shandong Province. It is high-tech enterprise which shifted from military technology (Belonging to Nuclear industry system previously). Main products are pneumatically operated spillway gate, rubber dam and rubber belt products.
The workshop is 22,000 square meters, equipment 200 sets, workers 230. The company owns 11 patents for invention, 18 patents for utility. Our rubber dams, air bladder support gate have already been included in excellent project tender recommendation directory of national Ministry of Water Resources, passed the technical evaluation of National Water Resources Experts Committee. We provide comprehensive water management services such as river channel improvement, water purification,ecological restoration and landscape enhancement, and are widely used in nuclear power security, power station water storage, water conservancy flood control, sediment dredging and etc.With the full capacity of design, production, installation and after sales, more than 100 spillway gates were built by Sunny in domestic. Our products also export to Italy, Thailand, Philippines, South Africa, Argentina etc.
Rubber dam Classification
Advantages:
Rubber dam has the following characteristics compared with conventional sluice dam:
1. Low cost and capital input, investment reduced by 30%-70%, save steel by 30%-50%, cement saved by about 50%, wood saved by over 60%.
2. Short construction period: air bladder installation generally need only 3-15 days, the project can be accomplished and attract benefits in the same year.
3. Dam body is made of flexible materials with shock resistance and foundation anti-deformation capability, good sealing effect, complete collapse capability, and no water resistance.
4. Used for urban river construction, the colors and beautiful styles are conductive to create features and beautify the environment.
5. The service life is designed up to 15 years, usually with less maintenance and management convenience.
The whole dam air bag strength
The whole dam airbag, also called none overlap joints dam airbag. It produce according to the whole manufacturing technology, which realized by the super large curing press and the patented technology of folding and curing the sulfide. The whole dam bag has no second time splicing and vulcanization process, and the tensile strength of all directions can be consistent, so there is no obvious weak part, which will improve the safety greatly. The service life is fully guaranteed.
1. No weak parts in overlapping, obviously improved in performance, safety and reliability.
2. Flat dam airbag, without "knots" and "bump" phenomenon, more beautiful.
3. The production efficiency is greatly improved, and the delivery is short.
4. Reduce the cost, and increase the investment and comprehensive social benefits.
