Description
[technical field]
The present invention relates to a kind of water-soluble metalworking liquid and a kind of method of cutting hard and fragile material, and be particularly related to a kind of water-soluble metalworking liquid with AS with height cleaning.
[background technology]
The treaty of relevant green subject under discussion; Main purpose is to stablize the content of atmosphere percent of greenhouse gases concentration in the human factor that can prevent dangerous interference weather system; And along with energy-saving and carbon-saving, environmental protection subject under discussion surge forward; Go up successively down in International Crude Oil, energy-conservation and exploitation substitute energy more and more receives international attention.
Solar photoelectric technology (photovoltaic technology) is the important emerging energy-conservation and substitute energy industry of 21 century.The solar photoelectric technology is to utilize sunshine and material to interact directly to produce a kind of pollution-free and reproducible energy of electric power; Especially solar cell can't discharge in use and comprise the gas that not hoping such as carbonic acid gas exists, and so can improve the ecological environment, solve problems such as global greenhouse effect.
The production process of solar cell; Be that raw material from the upper reaches is silicon (Si), by polysilicon long brilliant become crystal bar (ingot) after, process Silicon Wafer (wafer) through after repairing angle, section, etching again; Behind cleaning, printing, vapor deposition, become the main raw material of solar cell (solar cell) again.Because the electric power that single solar cell is exported is limited; For improving generated energy; Usually can many solar cell parallel connections be assembled into module (module), the setter (inverter) of straight/alternating-current power conversion is responsible in collocation at last, builds and is set to solar photovoltaic system (PV System).
Along with the solar photoelectric technical development so far, the scroll saw cutting technique has become the method for present solar monocrystalline silicon and polysilicon section usefulness.Scroll saw is cut with dual mode, and one is to use the cutting of bonded-abrasive scroll saw, and another is to use the cutting of free abrasive scroll saw.Bonded-abrasive adopts diamond fretsaw saw silk usually, and it is that the diamond abrasive grain of high firmness, high-wearing feature is electroplated a kind of parting tool that on the steel wire base material, is made into securely, has remarkable advantages such as high firmness, high-wearing feature.Because diamond abrasive grain is attached after Steel Wire Surface, the steel wire base material does not directly contact with workpiece, thereby the steel wire life-span can be improved greatly, and cutting efficiency and precision are also higher.Person in addition, the action principle of free abrasive scroll saw cutting is that silit (SiC) particulate is cut liquid and brings saw kerf into; The saw silk is applied to the power on the abrasive particle, drives abrasive particle and rolls along cutting surface, and the abrasive particle of extruding simultaneously embeds cutting surface; And then form flakes bits and surface crack, form cutting action.
Generally, the kind of cutting fluid can be divided into haply: oil soluble cutting fluid (or water-insoluble cutting fluid), water-soluble metalworking liquid, gaseous state cutting fluid and semi-solid cutting fluid.In the known technology, the oil soluble cutting fluid mainly is to be basis and the finish that adds elements such as sulfur-bearing or chlorine with MO.The mixture that water-soluble metalworking liquid mainly is made up of water, tensio-active agent, oiliness modifying agent, anti-extreme-pressure additive and rust-preventive agent; In specific words; Water-soluble metalworking liquid can comprise MO, soap or sulfuric ester and compositions such as higher alcohols or fatty ester; Wherein soap or sulfuric ester are as emulsifying agent, and higher alcohols or fatty ester are as wedding agent.Known oil-soluble cutting fluid like that or water-soluble metalworking liquid, in working angles if temperature rises, with have smolder or even danger on fire, so its shortcoming is for only descending use in low cutting temperature operation.
Whether cutting fluid has excellent results, needs usually to consider three factors, and comprise: (1) cutting fluid sole mass comprises: dispersion agent, tensio-active agent, organic bases, permeate agent, lubricant, skimmer, rust-preventive agent, mould inhibitor and emulsifying agent etc.; (2) cutting fluid comprises the influence of environment: nontoxic, harmless, soluble in water, volatility is little, biological degradability is high, to human body can not injure with can not the smell pollution etc.; And (3) cutting fluid various performances of using the back to be showed, comprise: reduce coefficient of friction, reduce cutting resistance, good lubrication effect, good osmosis, good cooling effect and good cleanup action etc.
In the scroll saw cutting technique, lubricating property is extremely important, and the lubrication principle is to utilize the polar group of molecule to be adsorbed on the metallic surface; To form physics and chemical lubricant film; General commonly used lipid acid is as oiliness improver, but when if the temperature in friction zone exceeds 100 ℃, then lubricant film will lose effect; Need to add extreme pressure agent (extreme pressure) this moment and improve the extreme pressure agent such as sulfur-bearing, phosphorus or chlorine element.
Greasing comprises hydrodynamic lubrication usually, the limit is lubricated and three kinds of processes of extreme boundary lubrication.Hydrodynamic lubrication is that lubricating oil is done the physics separation between tool face and workplace, does not have chemical reaction and takes place, and the oil that viscosity is higher or thicker has bigger molecule, and therefore preferred separating effect is arranged.The limit is lubricated to be that polar material is added in the MO, can be formed with the organic film of chemical bonded refractory in workpiece face and tool face, and this film can be attached on the metallic surface; Therefore wear resistance is than the better effects if of isolating workpiece and cutter merely with oil molecule, and in the known technology, lipid material uses already and is the MO additive; Be used for processing the lubricating oil that can produce suitable organic film,, therefore help the prolongation of cutter life because lipid has extremely significant effect to improving cutting; In addition, the lipid additive can produce organic membrane, and it can avoid the direct contact of metal; The fusing point that is increased to film up to temperature all has the protection effect before, and temperature is about 100 ℃ to 200 ℃.And, then need add extreme-pressure additive in the man-hour that adds of more high pressure, high-temperature.Extreme boundary lubrication is in most cut, and cutter front end temperature is higher than the scope of the lubricated temperature in limit, therefore needs to use the additive that can produce the higher melt film.
Extreme-pressure additive is used in extreme boundary lubrication in greasing usually, and this extreme-pressure additive is divided into oil soluble and water-soluble.The oil soluble extreme-pressure additive, main is main with compounds chloride and extreme pressure active elements such as sulphur or phosphorus.When use contained the extreme-pressure additive of chlorine, sulphur or phosphorus and so on, additive can produce chemical reaction with the metallic surface, formed the metal derivative film of one deck low-frictional force.It has the effect of similar dry lubrication, can prevent the wearing and tearing and the fusion of metallic surface, and for example the chlorine film can be anti-600 ℃, and the sulphur film can be anti-1000 ℃.Because adding in the water-soluble metalworking liquid, the extreme pressure agent of sulfur-bearing, phosphorus easily metal is produced corrosion, P contained compound especially, and it because form mikrobe abundant nutrition source easily, and receives strict control when discharging of waste liquid.Chloride extreme pressure agent, clorafin etc. for example, because cheap, effect is also good, though its corrodibility can add suitable inhibiter and be inhibited, can't meet the requirement of international Halogen standard.Another kind of extreme pressure agent is a Water Soluble EP Additives, is that extreme-pressure additive and borate extreme-pressure additive are main with molybdenum mainly.But molybdenum is an extreme-pressure additive to cost an arm and a leg, and borate extreme-pressure additive solubleness is too little.
Therefore, for the problem that solves above-mentioned prior art and for can meet environmental regulations, need exploitation new cut liquid to meet above-mentioned demand.
