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 wast...

Abstract
The invention relates to diamond wire cooling liquid as well as a preparation method and application thereof. The diamond wire cooling liquid is prepared from the following raw materials: water, macromolecular polyether, fatty alcohol-polyoxyethylene ether, alkynediol polyoxyethylene ether, organic acid, organic amine and a defoaming agent, and the diamond wire cooling liquid is micro-emulsified diamond wire cooling liquid. According to the invention, water and polyether are taken as main raw materials, the ratio of polyether to water is controlled and the surfactant is added cooperatively, so that in the using stage of the cooling liquid, the micro-emulsifier form enables an emulsion to have good lubricating and cooling effects, and in the recycling stage, the ratio of water to ether in the cooling liquid is changed, the high-molecular polyether is gradually gathered into a macromolecular state from an original micron-sized state, so that filtering removal is facilitated in a filter pressing stage, and the technical purpose of convenience in recycling is achieved on the premise of ensuring the cooling and lubricating effects.
Description
technical field [0001] The invention relates to the technical field of cutting fluids, in particular to a diamond wire cooling fluid and its preparation method and application. Background technique [0002] Diamond wire cutting is a cutting technology that uses a metal wire coated with diamond to achieve slicing at high speed. It has the advantages of fast cutting speed, thin slit, and good surface quality. It is a more sustainable development. Application Technology. The factors that play a key role in cutting quality in 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 or even broken wires. Coolant is a kind of cutting fluid that lubricates, cools and cleans during the cutting process, and at the same time takes away the silicon powder produced by cutting, so that the cutting can be carried out smoothly, thereby obtaining high-...
