ENVIRONMENTALLY-FRIENDLY FISHING WEIGHT AND A MANUFACTURING METHOD OF THE SAME CAPABLE OF IMPROVING THE SPECIFIC GRAVITY OF THE WEIGHT BY MIXING SILICA CONTAINING CEMENT AND SODIUM SILICATE

摘要

PURPOSE: An environmentally-friendly fishing weight and a manufacturing method of the same are provided to satisfy the demands of users by preventing the destruction of the weight without using pollutant materials.;CONSTITUTION: A manufacturing method of an environmentally-friendly fishing weight includes the following steps: 30-35 volume% of sand, 30-35 volume% of gravel of 5 to 10mm, and 35-40 volume% of cement are stirred; 65-75 volume% of the primary stirred product and 25-35 volume% of liquid sodium silicate are stirred to prepare a secondarily stirred product; the secondarily stirred product is supplied into molding frames(51, 52) to be compressed using a compressive press; a pinhole pin is inserted into the pinhole pin insertion part of the molding frame to form pinholes; the molding frame compresses and combines molded products; the molded products are inserted into a pinhole pin holder and rapidly frozen-dried; and the molded products are coated with liquid sodium silicate.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Third process
