Problems solved by technology

The cooling effect of the cutting fluid enables the entire diamond wire cutting process to be carried out in a low temperature environment. However, in the process of cutting crystal silicon with diamond wire, there will be loss of crystal silicon in the form of silicon powder, which is mixed in the cutting fluid. Some studies have found that, The main components of the waste slurry formed by cutting are: 35%-40% silicon powder, 40%-50% water-based cooling liquid, 1%-3% diamond particles and metal impurities. It is often not recyclable after use. On the one hand, it will cause waste of materials, which is not conducive to the resource utilization of crystal silicon. A diamond wire coolant that is easy to separate and recover is particularly necessary

Abstract

The invention relates to a diamond wire cooling liquid and a preparation method and application thereof. The raw materials of the diamond wire cooling liquid include water, polymer polyether, fatty alcohol polyoxyethylene ether, acetylene glycol polyoxyethylene ether, organic acid, organic Amines and defoaming agents, and the diamond wire cooling liquid is a micro-emulsion diamond wire cooling liquid. The invention uses water and polyether as the main raw materials, and controls the ratio of polyether to water and adds surfactants. In the stage of use as a cooling liquid, the form of the micro-emulsifier makes the emulsion have good lubrication and cooling effects. In the utilization stage, the water-to-ether ratio in the cooling liquid changes, and the polymer polyether gradually aggregates from the original micron-scale state to a macromolecular state, which helps to filter and remove in the filter-pressing stage, and realizes the invention in ensuring cooling and lubrication. On the premise of the effect, it is convenient for the technical purpose of recycling.

Description

technical field [0001] The invention relates to the technical field of cutting fluid, in particular to a diamond wire cooling fluid and a preparation method and application thereof. Background technique [0002] Diamond wire cutting is a cutting technology that uses diamond-coated metal wire to realize slicing at high speed. It has the advantages of fast cutting speed, thin slit and good surface quality. Application Technology. The factors that play a key role in the cutting quality of diamond wire cutting single polycrystalline silicon wafer technology mainly include diamond wire and coolant. If the two cannot achieve a good synergy, there will be various risks of poor cutting and even wire breakage. Coolant is a kind of cutting fluid that plays the role of lubricating, cooling and cleaning during the cutting process, and at the same time takes away the silicon powder produced by the cutting, so that the cutting can be carried out smoothly, thereby obtaining high-quality ...
