Description

Glass cutting fluid containing gemini quaternary ammonium salt sedimentation agent Technical Field The invention belongs to the technical field of LCD glass processing, and particularly relates to a glass cutting fluid containing a gemini quaternary ammonium salt sedimentation agent. Background In CNC processing, the cutting fluid contains fine solid particles which cannot be filtered, the fine solid particles are pollution sources which directly lead to deterioration of the cutting fluid, once the impurity content in the cutting fluid and the grinding fluid is improperly controlled, the problems of bacterial breeding, pH value reduction, filter blockage, cutting fluid quality reduction and the like in the cutting fluid are caused, and finally, the adverse effects of processing quality reduction, efficiency reduction, cutting fluid spoilage, processing machine tool corrosion and the like are caused, and the fine solid particles mainly come from metal chips generated in the processing, abrasive particles generated by tool wear, grinding wheel sand dust and other impurities (such as guide rail oil, hydraulic oil and the like) mixed in the processing can damage a machine tool, a tool and the cutting tool, and the cleanliness and stability of the cutting fluid are reduced, so that the processing quality and the efficiency are influenced. Therefore, to ensure long-term stability of the quality of the cutting fluid, and to ensure the processing quality and efficiency, these pollution sources must be removed. The grinding of the cutter produces a large amount of fine powder particle scraps such as iron powder and carbon powder, the scraps have good suspension property and are not easy to settle and separate, so that a large amount of powder is adhered to the cutter blade to cause the cutter blade to have insufficient sharpness, the processing speed is seriously affected, meanwhile, the brightness and precision of the processed product are greatly affected, even the defective rate is greatly and rapidly increased, moreover, the powder is mixed in the diluent of the cutting fluid to seriously affect the process monitoring of operators in the processing process, and the glass cutting fluid and the grinding fluid are easy to grow bacteria due to too many impurities, the quality of the glass cutting fluid and the grinding fluid is excessively standard, the performance of the glass cutting fluid is reduced, even the cutting fluid is deteriorated, and the service life of the glass cutting fluid is also affected. In addition, with the development of modern technology and the improvement of environmental awareness, future cutting fluids will trend more and more towards environmental protection, and simultaneously the functions and effects will be more superior. The environment-friendly cutting fluid also has better antibacterial performance, is not easy to grow bacteria and can not cause pollution. In addition, the cutting fluid has multiple functions, so that the machine tool and the cutter can be effectively protected, and the processing quality and the processing efficiency are improved. It is also mentioned that high performance, long life, low pollution cutting fluids and their waste liquid treatment techniques are key directions for future development. The safety and stability control of glass cutting fluids are increasingly strict, not only in terms of protection of operators, but also in terms of protection of equipment and processing materials. In order to meet the requirements, the development direction of the modern glass cutting fluid is more focused on environmental protection and functionality so as to ensure that the processing precision, the efficiency and the yield can simultaneously meet the processing technology requirements of glass under the processing conditions of high rotating speed and high feeding rate. Disclosure of Invention The invention aims to provide the glass cutting fluid containing the gemini quaternary ammonium salt sedimentation agent, which can improve the sedimentation performance of glass powder, solid particles and metal ions, reduce scratches on the surface of glass in the grinding process, ensure the yield of the glass, has excellent lubrication and rust resistance, delays the aging of a cutter workpiece, prolongs the service life of the glass cutting fluid, is nontoxic and does not damage the safety of skin protection operators, and is environment-friendly.
