(1) the upper strata oiliness of manufacturing of the present invention and lower floor's water-based have good lubrication and cooling performance.
Plant oil based lubricant is take the product of plant as the basis.Their moiety can satisfy special processing property and require and technical requirements through refining.By the composite lubricating film layer that vegetables oil provides, its intensity is high, and lubricity is good.Therefore, the lubricity of this class cooling fluid is much higher than other mineral oil.In addition, plant oil based product has more effective and more durable lubricity than other alternative cooling fluids.Even the processing of material requirements heavy cutting, the plant oil based cooling fluid of using also need not add EP (anti-high pressure) additive.Adopt the lubricant of vegetables oil technology, its price is higher than substitute products.In order to improve its biological stability, need the more expensive composition of interpolation expense.But, to compare with alternative lubricant, its extra expense that increases can be by boosting productivity and being offset by the method for other various reduction costs.
The high lubricating property of vegetables oil is determined by the basal component of vegetables oil molecule and the chemical structure of itself.Take the cooling fluid of vegetables oil as the basis, its lubricity results from intrinsic " oiliness " of vegetables oil composition, and this specific character is the result who is directly caused by vegetables oil " clever molecule ".This quasi-molecule is very long, and is very heavy, has bipolarity, that is: the two ends of molecule are with opposite electric charge.Two " extremely " of molecule have very strong chemical affinity to the metallic surface, and they are adsorbed on the metallic surface tightly as small magnet.The vegetables oil molecule is arranged on the metallic surface vertically, closely, equably, and the result forms thick, solid, the durable composite lubricating film of one deck on its surface.The solid composite lubricating film of this layer improved the ability of vegetables oil absorption pressure.
On the contrary, the molecule of mineral oil is not to be with polarity.Their arranged evenly on the metallic surface are irregular, and the lubricant film that therefore produces is relatively weaker.The viscosity index of vegetables oil is higher, just more can guarantee the lubricating property that it is stable in operating temperature range.Along with the raising of processing temperature, the reduced viscosity speed ratio mineral oil of vegetables oil is slow.On the contrary, along with the reduction of temperature, the liquid fluidity of vegetables oil is better than mineral oil, is conducive to separate with workpiece with smear metal.And its fusing point is higher, is conducive to improve metal removal rate, reduces the formation of smog, reduces the danger of presence of fire.
The vegetables oil bulk of molecule is very even, and mineral oil bulk of molecule variation range is very large.Therefore, the physical property of mineral oil, for example its in when evaporation and the viscosity when reaching boiling point be greatly affected.The higher of vegetables oil and larger weight make it extremely low because of the loss that diffuse and evaporation causes.Because its molecular wt is higher, its sediment is limited in the less scope.Can be like this Working environment that people build a health and cleaning, airborne smog reduces in a large number, and vegetables oil can not produce any toxic side effect to environment.
Through experiment, adopt the vegetables oil technology, have sizable superiority cutter life to boosting productivity and improving.In the course of processing, adopt plant oil based cooling fluid can improve smooth finish and the tolerance of dimension of finished surface, improve complete processing level, ability and boost productivity.For example, add man-hour automobile gear is carried out drilling, adopt plant oil based cooling fluid after, can make improve 3 times the work-ing life of drill bit.In addition, when producing titanium metal and stainless steel medical treatment implantation piece, adopt the vegetables oil technology after, made output increased 10%, also make simultaneously the cutter expense reduce by 50%.Also have an example more can describe the problem: in the automotive industry Application Areas, adopt plant oil based cooling fluid after, make the screw tap of machined steel workpieces improve 15 times work-ing life.
In the machining Application Areas, alien crop oil base cooling fluid can make the mechanical cutting performance improve comprehensively.As a technology through practical proof, since the sixties in 20th century, vegetables oil is considered to have super always.Take the lubricating fluid of vegetables oil as the basis, demonstrated the lubricating fluid that its processing characteristics is better than mineral oil and synthesizing formula greatly in the major applications field.These superiority-process-cycle shortens, changes trouble-free operation prolongation pitch time between the cutter, the quality raising-major part of workpiece should give the credit to the use of plant oil based metal working lubricant liquid and higher lubricity thereof.Adopt plant oil based cooling fluid in complete processing, productivity can improve 20%～30%, and cutting-tool's used life can improve more than 50%.Therefore, no matter be the oil in water emulsion of upper strata fatty acids glyceryl ester or the fatty acids ethanol ester of bottom, its oilness and cooling all are justifiable.
(2) upper strata of manufacturing of the present invention and bottom lubricant all have good cleaning.
The present invention crosses the emulsification of heating by the adding tensio-active agent to the vegetables oil back warp to form oil in water emulsion, thereby its surface tension descends, and the nonionogenic tenside itself that adds has hydrophilic and lipophilic group, such as 6501 (the Fatty Alcohol(C12-C14 and C12-C18) alkylolamides) that add, cleaning performance own is just good, degreasing power is strong, and is the major ingredient of preparation industrial cleaning agent.Thereby this lubricant has fabulous cleaning performance.
(3) except above-mentioned functions, also has preferably antirust function.The additive urea, 6501 (Fatty Alcohol(C12-C14 and C12-C18) alkylolamide) that joins in the vegetables oil itself is exactly good rust-preventive agent, and ferrous metal is had stronger antirust function.
