| abstract |
One example of the present invention provides a material for anti-caking, delaying or removing, comprising copper sulfide and a polymer resin and being in master batch chip, yarn or fabric form. The material for preventing, retarding or removing algae according to the present invention contains copper sulfide, which can effectively prevent, retard or eliminate algae, and can significantly reduce the cost for preventing, delaying or eliminating algae . In addition, the material for prevention, retardation or removal of algae according to the present invention is formed in the form of a master batch chip, a yarn or a fabric so that it is easy to handle and the copper sulfide is gradually released, so that it can be used for a long time. Further, the filter in which the material for preventing, retarding, or removing algae according to the present invention is accommodated in a predetermined receptacle is easy to install even in a narrow water channel, and the polymer resin can be recycled after the performance deterioration. |
