Preparation process of solid floating ball for marine product culture

Abstract

The invention discloses a preparation process of a solid floating ball for marine product culture. The preparation process of the solid floating ball for marine product culture comprises the followingsteps of floating ball shell forming, jacket mounting, foaming material casting and jacket dismounting. An inner cavity matched with the size of a shell is arranged in a jacket, and a heat exchange mechanism is arranged in the jacket. Through the above manner, the solid floating ball high in external strength and even in internal foaming can be obtained, the service life of the floating ball forculture can be effectively prolonged, and the problem that water enters a hollow floating ball due to shell damage, and consequently the floating ball fails is avoided; and the floating ball can be recycled and then utilized after the floating ball reaches the service life period, and resource and environment waste is further reduced.

Description

technical field [0001] The invention relates to the field of aquaculture floats, in particular to a preparation process of a solid float for mariculture. Background technique [0002] In recent years, my country has paid more and more attention to marine aquaculture and environmental protection requirements. The polystyrene foamed floating balls commonly used in marine aquaculture in the past can not withstand ultraviolet radiation and wind and rain erosion. Under normal circumstances, it will disintegrate and disintegrate in less than two years, and it will be scattered on the ocean to form white pollution. After being swallowed by farmed fish, it will remain in the organism and form a huge threat to the ecological circle. Therefore, this kind of floating ball is urgently needed. Upgrading to meet the dual requirements of environmental protection and production. At present, someone has invented the method of pouring polystyrene foam plastic inside the plastic floating ball, ...

[0002] In recent years, my country has paid more and more attention to marine aquaculture and environmental protection requirements. The polystyrene foamed floating balls commonly used in marine aquaculture in the past can not withstand ultraviolet radiation and wind and rain erosion. Under normal circumstances, it will disintegrate and disintegrate in less than two years, and it will be scattered on the ocean to form white pollution. After being swallowed by farmed fish, it will remain in the organism and form a huge threat to the ecological circle. Therefore, this kind of floating ball is urgently needed. Upgrading to meet the dual requirements of environmental protection and production

At present, someone has invented the method of pouring polystyrene foam plastic inside the plastic floating ball, but this process has not been applied in substantive production, because the second molding of polystyrene requires the mold to press the compression ratio before it can be formed, and the second The temperature during secondary molding is 180°C~200°C. At this temperature, the plastic float shell is easy to melt and deform.
