When the upward buoyancy force and the downward gravity force of the object are equal, and the center of gravity of the object and the buoyancy center are on the same vertical line, the floating body is balanced. The floating body will tilt after being disturbed by the outside world (such as the effect of wind and waves). After the external disturbance disappears, the ability of the floating body to return to its original equilibrium state is called balance stability. The intersection point M of the buoyancy action line of the buoyant body at equilibrium and at the post-tilt position is called the fixed inclination center. When the M point is higher than the center of gravity C, the gravity and the buoyancy force after tilting constitute a turning moment to restore the buoy to its original equilibrium position , The floating body is in stable balance. Then, the above two forces will form a turning moment that makes the floating body have a more tendency to tip, and the floating body is in an unstable balance.
The balance of the floating body is a very important issue in ship design and caisson floating transportation. It is a medium-density polyethylene floating body. Its performance characteristics are light weight, easy to install and handle, and the material is medium-density polyethylene.
Plastic floating body is medium density polyethylene floating body.
At the end of the 1990s, the China Water Conservancy and Hydropower 13th Engineering Bureau Co., Ltd. rubber and plastic products factory was introduced into the Chinese market and improved to obtain patents.
Basic Information
Plastic float, the shell is made of medium-density polyethylene with excellent toughness, filled with high-strength polyurethane foam. Reasonable structure and excellent performance. As the floating material of the dredging water pipeline in the dredging industry, it has become an alternative to traditional steel buoys.
Product performance characteristics:
1. Good toughness and excellent impact resistance, especially suitable for offshore construction.
2. Light weight, easy to install and carry, low transportation cost.
3. Corrosion resistance and long life. At present, the first batch of floats in our factory has been used for 8 years, and it is still in construction and application.
4. The price is low, and the performance ratio is significantly better than the steel buoy.
