Description

Improved manufacturing method of oyster shed floats

The present invention relates to a method for manufacturing oyster shed floats, in particular to an oyster shed float made through polyurea resin.

According to the fact that most of the oyster shed floats currently used in the open sea are made of styrofoam materials; the aforementioned materials have a lighter specific gravity than sea water, allowing the oyster shed to float on the sea; in addition, the conventional oyster shed floats are water-resistant, chemical-resistant, and It has excellent heat resistance and impact resistance, so the conventional oyster shed floats are popular with oyster farmers.

However, the components in the sea water are easy to decompose the oyster shed buoys, and the styrofoam is easy to be damaged, and the styrofoam is easy to cause environmental pollution on the coast.

In order to solve the problem of oyster styrofoam polluting the coast, the Tainan city government has banned the use of uncoated styrofoam oyster buoys in October of the Republic of China.

In order to respond to government policies and the serious problem of marine green pollution, many manufacturers have developed several environmentally-friendly oyster shed floats: 1. PE high-density plastic floats, 2. Polymer composite materials coated styrofoam floats 3. EPP foamable polypropylene float.

Although the above three types of environmentally friendly oyster shed buoys emphasize to avoid the easy decomposition of oyster shed buoys and cause marine environmental pollution, they are also light in weight, non-absorbent, strong in material combination, particles are not easy to detach, not easy to proliferate attached organisms, easy to bind, and have recyclable repeatability. Advantages; however, the aforementioned The manufacturing cost of oyster shed floats is still higher than that of styrofoam. If there is no government subsidy for oyster farmers, the cost of breeding will increase significantly.

The main purpose of the present invention is to provide an improved method for manufacturing oyster shed floats, which has the advantages of low cost, high environmental protection, recyclable remanufacturing, and no water absorption.
