Problems solved by technology

In the 1970s, the glued surface of porcelain insulators was often treated with grooves and knurling, but the strength of porcelain insulators treated by this method was not high after glued, and the glued parts were easy to break; The sand treatment method improves the strength of the insulator, and the dispersion becomes smaller, so the sanding process spreads
The square sand has sharp edges and corners, and the size is uneven, so it is easy to pile up sand after glaze and sand; part of the sand is easy to break or fall off due to the sand standing on the glued part, resulting in sand shortage and sand shortage; Hidden defects on porcelain parts due to stress concentration
[0004] According to the client's requirements, the applicant purchased several types of round sand from the market for the preparation of some porcelain insulators, but due to the mismatch in composition or performance, pieces fell off, and there was no sand glaze in large areas of glued parts. , deviated from the fundamental purpose of Shangsha

Abstract

The invention relates to round sand for a porcelain insulator and a preparation method and application of the round sand, and belongs to the technical field of insulators. The round sand for a porcelain insulator comprises the following raw materials in percentage by weight: 31-38% of bauxite, 5-9% of kaolin, 17-23% of flux minerals, 19-26% of elutriated soil, 10-13.5% of calcined talc, 1.5-2.8% of BaCO3 and 3.5-5.3% of a production blank, and the sum of the mass of the raw materials is 100%, and 0.15-0.3% of a dispersing agent is added. According to the round sand for the porcelain insulator,the formula design is simple and scientific, the prepared round sand is uniform in particle size and free of layering and stripping, the phenomena of sand piling and shakeout are avoided in the usingprocess, and the product strength is high. The invention further provides a simple and feasible preparation method and application, and industrial production is facilitated.

Description

technical field [0001] The invention relates to round sand for porcelain insulators, a preparation method and application thereof, and belongs to the technical field of insulators. Background technique [0002] Most insulators are assembled from porcelain parts and metal accessories. Glue binding is an assembly method that permanently joins two or more porcelain parts or porcelain parts and metal accessories with adhesives. Porcelain insulators generally use cement as the adhesive. Since the porcelain parts and metal accessories are circular products, and the surface of the porcelain parts is glazed, its smoothness is relatively high. In order to increase the bonding strength of the assembled products, it is necessary to roughen the glued surface of the insulator. In the 1970s, the glued surface of porcelain insulators was often treated with grooves and knurling, but the strength of porcelain insulators treated by this method was not high after glued, and the glued parts we...
