Problems solved by technology

Due to the nature of the sand and liquid commonly used at the present stage, for the waste mortar that has been placed for a long time, there will be problems that the sand will sink to the bottom and it is extremely difficult to stir and disperse again. Therefore, shorten the regeneration cycle and reduce the labor intensity of the workers in the treatment process. Improving the yield of recycled products is a common requirement for sand, liquid properties and regeneration treatment process

Abstract

The invention provides a water-base cutting liquid for hard and brittle materials. The liquid is characterized by comprising the following components in percentage by weight: 70 to 95 percent of poly-alkoxy compound, 0 to 5 percent of extreme-pressure resistant chelating agent, 0.001 to 5 percent of anti-settling re-dispersing agent and 4 to 20 percent of deionized water. The cutting liquid of the invention has the characteristics of no pollution and low metal impurity content; at the same time, the stability of a motar formed by mixing the cutting liquid and grinding material carborundum is high and grinding material carborundum re-dispersing capacity is high; and the cut product has the advantages of high yield, high qualification rate, high surface cleanliness, easy cleaning and the like. The invention also relates to the application of the cutting liquid to processing monocrystalline silicon, polycrystalline silicon, germanium, gallium arsenide, quartz, gallium indium nitride or precious stones.

Description

technical field [0001] The invention relates to a water-based cutting fluid, in particular to a composite water-based cutting fluid for (multi-) wire cutting of hard and brittle materials, a preparation method and application thereof. Background technique [0002] In recent years, as countries around the world attach great importance to solar energy, a green resource, the solar photovoltaic power generation industry has become the focus of common attention worldwide. With the rapid development of multi-wire cutting technology for hard and brittle materials such as polysilicon, monocrystalline silicon, germanium, and gallium arsenide, especially in the solar energy industry, the wafer products of polysilicon materials have transitioned from a buyer's market to a seller's market, and the price of wafer products has gradually increased. As a result, slicing manufacturers are paying more and more attention to costs. Improving product quality, reducing process consumption, increa...
