Abstract
The invention relates to a ceramic grinding agent, belonging to the field of grinding agents. The ceramic grinding agent provided by the invention is mainly used for grinding silicon nitride ceramic balls. The grinding agent consists of the following components in percentage by mass: 5%-50% of diamond particles, 50%-90% of dispersant, 0.1%-3% of calcium hydrophosphate, 0.5%-2% of sodium tripolyphosphate, 0.5%-2% of sodium dodecyl sulfate and 0.5%-2% of sodium silicate. The grinding agent mainly contains the high-strength diamond particles, the dispersant, a grinding assistant and a dispersing assistant. The grinding agent has the advantages that the grinding efficiency is high and is increased by 30%-50%, the pollution to ceramic bodies is little, the grinding efficiency is increased, and the grinding time is shortened.
Description
Technical field
The present invention relates to a kind of ceramic sanding agent, belong to the abrasive field.
Background technology
Ball bearing is a kind of of rolling bearing, and the ball ball is contained in the centre of interior steel ring and outer rim, can bear larger load.Wherein, ceramic ball bearing receives much concern because of its unique characteristics and wide application field.What at present, application was more is silicon nitride ceramic ball bearing.Its advantage is: tripping speed is high, precision stability good, staring torque is little, ceramic ball bearing rigidity is high, dried runnability is good, the life-span is long, is very suitable for keeping high precision, long time running under high speed, high temperature and burn into radiation condition.In addition, the hardness ratio bearing steel of silicon nitride ceramics is high 1 times, and Young's modulus is approximately high by 1/3, and under the condition of same load, the recoverable deformation of silicon nitride ceramics is little, so, use the machine tool chief axis of ceramic ball bearing to have good running accuracy.
For running precision and the work-ing life that guarantees ceramic ball bearing, to the Ceramic Balls sphericity require highly, simultaneously owing to itself being high-strength material, it is ground then more difficult.
Summary of the invention
The purpose of this invention is to provide a kind of ceramic sanding agent, be mainly the abrasive for the polishing silicon nitride Ceramic Balls, this abrasive mainly comprises high-intensity diamond particles, dispersion agent, grinding aid and dispersing auxiliary.It is high that this abrasive has mill efficiency, ceramic body polluted lack, and improves mill efficiency, reduces milling time.
