Abstract

The invention provides a cooling liquid for diamond wire cutting. The cooling liquid comprises the following components in percentage by weight: 16-26% of a stabilizer, 0.5-2% of a water-soluble lubricant, 1-4% of an extreme pressure agent, 3-8% of a preservative, 1-4% of a wetting agent, 0.01-0.04% of a defoaming agent and the balance of deionized water. The cooling liquid has the advantages of high efficiency, low toxicity and good water solubility, and can effectively inhibit the damage of microbial growth to the stability of the cooling liquid.

Description

technical field [0001] The invention relates to the field of coolant, in particular to a coolant for diamond wire cutting. Background technique [0002] Diamond wire cutting technology replaces traditional mortar cutting. It uses electroplating technology to bond diamond and steel wire to attach diamond abrasive to the surface of steel wire, and directly acts on the surface of silicon rod or silicon ingot to produce grinding with diamond wire to achieve cutting. Effect. Diamond wire cutting has the characteristics of fast cutting speed, less silicon consumption, and low material loss. Due to the high efficiency of diamond wire cutting and the use of pure water as the main solvent, more heat will be generated on the surface of the wire saw and the silicon rod, which needs to be dissipated and lubricated in time by the cooling liquid; to suppress the reaction of silicon powder and pure water during cutting. Fire accidents; therefore coolant is used in diamond wire cutting te...
