- Introduction of rubber air bag2024-04-25Rubber air bag, also known as concrete prefabricated hollow plate rubber inflatable core mold, bridge inflatable core film, rubber inner mold, is a kind of internal mold of different shapes that can expand and contract by vulcanizing rubber polymer characteristics and high strength fiber cloth. It is mainly used in the casting and forming engineering of the concrete beam of highway bridge. It is also used in culvert drainage projects. After the rubber air bag is filled with compressed air, the air bag stretches and expands to meet the design requirements of its cross-section, and the inflation pressure is determined according to the manufacturer's logo. It is easy to use, economic and durable, can be used repeatedly for nearly a hundred times, soft contraction when not inflated, arbitrary folding, curling, inflation after expansion has enough strength to withstand the pressure of concrete. It can replace the original wooden mold, bamboo mold and steel mold, and can be reused many times. It is a kind of concrete products supporting products to reduce costs and speed up construction progress.
- Current situation and development trend of Chinese rubber industry2024-04-25China is one of the fastest developing countries in the world rubber industry, while the rapid economic growth of the rubber industry, its industrial structure and product structure have been further optimized.
During the "Eleventh Five-Year Plan" period, the annual growth rate of the industrial output value of the domestic rubber industry reached 36%, and the annual consumption growth rate reached 12.25%. Among them, the average annual growth rate of radial tires reached 28.5%, and the annual growth rate of tire exports was as high as 34.94%. - Rubber fender features and applications2024-04-25Solid rubber fender has high energy absorption and reaction, and has the advantages of low cost, long service life, simple installation and maintenance, etc. It is the most installed protective device in docks and shipyards.
Rubber fender, also known as rubber fender, is an energy buffer device used in port terminals or ships to slow the impact or shock of ships and docks or ships and ships when berthing or mooring, so that ships and docks are free from damage.
Rubber fender has the characteristics of good elasticity, high energy absorption, easy maintenance, long service life and easy to produce a large number of types, and is widely used in Japan, Europe and the United States and Southeast Asian countries. Rubber fender can not only protect the ship and the dock, but also reduce the horizontal load acting on the dock, improve the docking capacity of the dock, make the new dock light and reduce the cost.
The size range of rubber fender is large. Conventional size products can be easily selected to match the vulcanization equipment, but the large-scale vulcanization equipment investment required for oversized products is too high, especially in the product batch is small, and it is not cost-effective to invest in buying large-scale vulcanization equipment. Solid rubber fender has high energy absorption and reaction, and has the advantages of low cost, long service life, simple installation and maintenance, etc. It is the most installed protective device in docks and shipyards.
