In sum, cooling-lubricant of the present invention is easy to heat radiation because lipid acid or the resinous acid an alkali metal salt that adopts belongs to anion surfactant, and it can improve the wetting action of water to diamond in the saw blade and wedding agent.Again because fatty acid alkali metal salt belongs to the carboxylate salt in the anion surfactant, has wettability preferably, it adsorbs the formation solid lubricant film mutually with diamond surface, reduced rock and adamantine frictional force and sawing temperature, can avoid the diamond oxidation and reduce diamond thermal shocking fragmentation.Also can produce lubricant film between tensio-active agent and matrix, reduce matrix---the frictional force between rock dust.Diamond wedding agent wearing and tearing normally cause by the wearing and tearing of landwaste, and rock is cut in the face of the wearing and tearing of saw blade wedding agent and cooling fluid are extremely accessory to the erosion of wedding agent, during sawing, before rock dust accumulates in cutting blade, causes that wedding agent repeats to grind.Because multiple metal such as W, WC in the diamond saw blade binder alloy and Ni and soap adsorption are very little, though and Cu, Zn, Mn ion have better adsorption with lipid acid and fatty acid sodium salt, but content is very little, so anion surfactant is to wedding agent---the lubrication of rock is all not so good.Adamantinely go out sword, necessarily require the wearing and tearing and the adamantine wearing and tearing synchronised or suitably leading of wedding agent.When wedding agent weares and teares when excessive, it is too high that diamond goes out sword, will diamond particles be come off.And the wedding agent wearing and tearing are relevant with cooling fluid composition, a wedding agent material wear ability and rock dust abrasive lapping ability, take all factors into consideration quality of stone material, diamond segment quality and lubricity, it is vital selecting suitable tensio-active agent, promptly have a critical lubricated concentration value, make adamantine wearing and tearing minimum and diamond to go out the sword cutting ability best.Diamond and wedding agent temperature descend rapidly with the increase of cooling liquid measure, have a critical minimum cooling fluid value.Can generate water-fast fatty acid calcium and fatty acid magnesium with lipid acid resinous acid an alkali metal salt owing to contain the aqueous solution of calcium ions and magnesium ions, produce precipitation; And Ca
2+, Mg
2+The grouan rock dust that ion again can the activated silicates mineral grain be formed makes it absorption and consumes a large amount of cooling fluids, therefore must improve the anticalcium magnesium ability of cooling fluid.Can adopt the method for earlier softening cooling fluid water, prevent the absorption of calcium ions and magnesium ions cooling fluid.Cooling fluid of the present invention adopts the strong nonionogenic tenside of anticalcium magnesium ability, and is composite with lipid acid resinous acid an alkali metal salt, and addition is very little to the oilness influence.Can form the mixing micelle, reduce critical micelle concentration, prevent and disperse fatty acid calcium and fatty acid magnesium precipitation.The cleanup action of stone material sawing cooling fluid is rock dust and the grease on the flushing diamond segment.The sawing heat is taken out of with cooling fluid, in case rock dust forms in a large number, and cooling fluid is when being not enough to remove rock dust, and diamond rises rapidly with the temperature that contacts of rock and rock dust with wedding agent, can produce spark because of rock dust obstruction diamond goes out the sword space, the diamond abrasion are increased.When lipid acid resinous acid generates an alkali metal salt in reaction,, can produce grease, stop up diamond and go out the sword space if the incomplete lipid acid resinous acid of reaction still exists.So should consider to keep a certain amount of rock dust according to quality of stone material, diamond segment quality and cooling fluid lubricity, so that the wearing and tearing wedding agent guarantees that effective cutting blade occurs.Guarantee that in addition enough pressure makes cooling fluid go out sword and directly cool off diamond by small, and wash away rock dust, eliminate grease, prevent to stop up.Consider above factor, according to the condition of production, carry out after specific aim adjusts that use the saw blade of cooling fluid of the present invention, on diamond segment, no grease occurs, it is good that diamond goes out sword, sparkless during use, diamond wearing and tearing and normally damaged.The granite stone powder surface of compositions such as aluminosilicate mineral is negative charge, repels each other to be difficult for precipitation, and sawing rock dust grain is thin, and the precipitation that descends is slow.When the rock dust concentration in the cooling fluid is too high, will increase the diamond segment abrasion, and must in time change, and therefore must take the precipitation measure.Cooling fluid of the present invention is used polymeric flocculant and inorganic electrolyte flocculation sediment rock dust, and rock dust splashes little, through the precipitation of settling tank, descend rapidly, can't be risen by the water pump pump, increase the validity period of cooling fluid, can regularly remove easily through the rock dust of post precipitation.Aspect flocculating effect, have an optimal polymeric flocculant flocculation concentration, surpass this concentration, major part is covered by flocculation agent already on the individual particle surface, have only seldom amount to make the new bonding of formations between particle, cause particle suspension and can not redeposition decline.The present invention utilizes the adsorption bridging effect of the charge neutralization and the polymeric flocculant of inorganic electrolyte, both can obtain good flocculating effect, reduces expenses; Can make rock dust be difficult for bad phenomenon occurring precipitating again because of the polymeric flocculant consumption rises too much or by the water pump pump.
