AI Technical Summary

Problems solved by technology

The sedimentation of glass powder is not obvious, and it will cause secondary scratches due to abrasive debris brought by the circulating liquid supply
If the amount of foam is too large, in addition to affecting the cleaning and settling properties of the grinding fluid, the existence of foam at the grinding contact point will cause "dry friction" and cause burns on the workpiece, seriously affecting the grinding efficiency and surface processing accuracy

Abstract

The invention provides a fully-synthetic water-based glass grinding fluid and a preparation method thereof. The glass grinding fluid is prepared from components in percentage by weight as follows: 5%-25% of a lubricating agent, 5%-15% of an anti-rusting agent, 0.25%-5% of a sinking agent, 1%-5% of a sterilizer, 0.25%-2% of a complexing agent, 0.05%-0.5% of a surfactant, 4%-15% of a pH stabilizer and the balance of water. The fully-synthetic water-based glass grinding fluid adopts a low-foam or foam-free raw material additive, and accordingly, the anti-foam and defoaming performance of the grinding fluid is guaranteed from the source; system instability caused by use of an anti-foaming agent in a conventional grinding fluid and the phenomenon of foam 'reemergence' caused by consumption of an antifoaming agent during cycle operation of the grinding fluid are avoided.

Description

technical field [0001] The invention belongs to the field of inorganic material processing, and in particular relates to a fully synthetic water-based glass grinding fluid and a preparation method thereof. Background technique [0002] Materials such as glass and quartz are thermally poor conductors of heat and are not easy to conduct heat. Therefore, the glass grinding fluid used in the grinding process generally chooses a water-based fluid with a large thermal conductivity and good cooling performance. At the same time, due to the hard and brittle nature of the glass itself, cracks are prone to occur, and it is difficult to achieve precision grinding. Therefore, it is required that the glass grinding fluid should have a certain alkali corrosion function: that is, OH - The existence of the glass reacts slowly with the glass, breaks the bridge oxygen bond of the silicon-oxygen tetrahedron in the glass, generates silicate with lower hardness, realizes plastic grinding, and r...
