Rotational molded culturing float ball and production method thereof

Abstract

The invention provides a rotational molded culturing float ball and a production method thereof. The rotational molded culturing float ball comprises a ball body, wherein the ball body is a hollow ball, the outer wall of the ball body is provided with a plurality of rope holes used for rope threading; an inflation port is provided with a gas core component, the outer portion of the inflation portis provided with an external coating layer completely coating the gas core component, and the external coating layer is in seamless connection with the ball body; the ball body is made from polyethylene, and compared with the prior art, photo-oxidation, thermal oxidation and ozone decomposition of the polyethylene are liable to happen, so that the polyethylene has a recycle and recovery function,has very far-reaching value, does not cause white pollution of the ocean, is processed and molded easily, and is soft, tough, lighter than water, non-toxic and light; the outer portion of the inflation port is provided with the outer coating layer completely coating the gas core component, and the outer coating layer and the ball body are integrated, so that the float ball of the structure does not leak air easily and has a long service life.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a rotationally molded culture float and a manufacturing method thereof. Background technique [0002] Breeding floating balls is one of the important breeding methods of aquaculture (such as mussels and asparagus). The upper ends of several floating balls are connected by ropes, and the lower ends are connected to objects used for aquaculture, which are put into the water for breeding. The most important thing is the foam breeding float, which has the following problems: 1. One of the sources of white pollution in the ocean, 2. Short life, 3. It can absorb water, 4. The buoyancy decreases with time. There are also floats made of hard plastic on the market. Balls, but the hard plastic is heavy, and a ball can weigh more than 20 kilograms. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved ...
