Problems solved by technology

[0002] The domestic electroplated diamond grinding wheel has exposed some problems in the process of use, and the outstanding performance is as follows: 1. The life of the grinding wheel is low. The average life of the domestic grinding wheel is only 1 / 3 of that of the German electroplated diamond grinding wheel, and the stability is poor. The main reason is that the domestic electroplating process is not up to standard , the diamond abrasive at the concave surface of the arc is not fixed firmly, it is easy to fall off, and the electroplating layer is often peeled off, which makes the processing impossible; Due to the defects in the electroplating process of domestic grinding wheels, the arrangement of diamond abrasives is too dense, the chip space is small, the grinding wheel is easy to block and slip, and the feed speed of the Borg plate has to be reduced; The proportion of board scrapping is as high as 8%

Embodiment Construction

[0008] Disclosed is a mixed metal abrasive used for surface cleaning of special seawater ballast tanks of ships and double-side sides of bulk carriers. It is characterized in that it is made by mixing low-carbon alloy steel shot and chrome-molybdenum alloy steel grit according to the ratio of 10%-30%:70%-90% by weight.

[0009] The method of the present invention is: after batching according to the above formula, put it into a mixer for mixing, put the mixed mixture into a twin-screw extruder for extrusion, and control the temperature of the first zone of the extruder at: 83±2°C; The temperature in the second zone is controlled at: 95±2°C; after the extruded sheet material is cooled, it is put into the pulverizer to be pulverized and ground into a powder of 140-180 mesh, and packed into the warehouse.

Abstract

A mixed grinding material is characterized by being prepared by mixing low carbon alloy steel balls and chromium molybdenum alloy steel sand according to the weigh proportion of 10%-30%:70%-90%. The mixed grinding material has the advantages of corrosion resistance, wear resistance, and strengthening, and can be used for corrosion resistance in various metal pipelines widely and machines in acid-base environments, can be used for strengthening casting pipes, and used as adhesion agents of rigid materials.

Description

technical field [0001] The invention belongs to the technical field of mixed metal abrasives, and in particular relates to a mixed metal abrasive used for surface cleaning of special seawater ballast tanks of ships and double-side sides of bulk carriers. Background technique [0002] The domestic electroplated diamond grinding wheel has exposed some problems in the process of use, and the outstanding performance is as follows: 1. The life of the grinding wheel is low. The average life of the domestic grinding wheel is only 1 / 3 of the German electroplated diamond grinding wheel, and the stability is poor. The main reason is that the domestic electroplating process is not up to standard , the diamond abrasive at the concave surface of the arc is not fixed firmly, and it is easy to fall off, and the electroplating layer often peels off in pieces, which makes the processing impossible; 2. The processing efficiency is low, about 1 / 2 of the efficiency of the German Burger grinding ...
