Mechanism of Organic Grinding Fluid of Ceramics Based on Long Carbon Chain Alcohol and Halogenated Hydrocarbons

摘要

This paper carries out grinding efficiency experiments on various formulas composed of long carbon chain alcohol and halogenated hydrocarbons with the first principle of grinding fluid as main evaluating index and finds via infrared spectrum testing that the conjugating ways of lubricating films between alcohol-type grinding fluid and ceramics is based on chemical adsorption or hydrogen bonding adsorption and generates alkoxy silane or polyalkoxy silane with perfect anti-friction action under the condition of grinding high temperature. With adding of halogenated hydrocarbons, it can further make grinding fluid with perfect extreme pressure property and improves grinding efficiency. Furthermore, this dissertation firstly introduces heat capacity as analysis means and discusses the influential factors on the removal rate of ceramics materials when using abovementioned grinding fluid. It is shown from the result that the material removal rate when silicon nitride ceramics grinding will increase with the augmentation of heat capacity.
